Detailed Description
Embodiments of the present invention are described in detail below with reference to the accompanying drawings.
The present invention relates to a pipe member including a metal part inside a body made of plastic so that the pipe member can be prevented from being twisted when the pipe member is combined with a pipe or other pipe members.
When the main body is made of metal, although the strength is excellent and twisting can be prevented, it is difficult to process the main body into a desired shape and the manufacturing cost is high.
Further, in the case where the main body is made of only plastic, although the processing and manufacturing unit price can be easily reduced, the pipe may be twisted when it is joined to a pipe or another pipe, and the pipe may be broken.
Accordingly, the present invention discloses a pipe fitting which is easy to process, has a low manufacturing unit price, and can prevent twisting.

The pipe fitting of the present invention is a pipe connector, and refers to a member to be coupled to a pipe, other pipe fittings, and broadly all devices having a flange, for example, a pipe such as a pipe, and may be named as a pipe coupling device. Wherein the tube may be made of plastic or metal, i.e. there is no limitation on the material. The tube includes all structures capable of moving fluid through the interior.
Referring to fig. 1 to 5, the pipe of the present embodiment is an elbow pipe, and may include a

The main body part 100a may have a streamlined shape. At this time, the main body portion 100a may have a 45-degree elbow structure as shown in fig. 3, and may also have a 90-degree elbow structure as shown in fig. 6. That is, when the main body 100a has a streamlined shape, the curvature may be variously modified.
The 1 st body flange portion 100b is formed at one end of the body portion 100a, and is a portion to be coupled with a pipe or other pipe.

As a result, the pipe can be joined to the pipe. Of course, the process of joining the pipe with other pipes is similar. The pipe of the present invention can be combined with all devices having flanges, and the combining process can be similar to the above-described combining process.
The 2 nd body flange portion 100c is formed at the other end of the body portion 100a, and is a portion to be coupled with a pipe or other pipe member. The bonding process is similar to that of the 1 st body flange portion 100 b.

The
The liner body portion 102a is formed inside the main body portion 100a and may have a curved shape.
The 1 st liner flange portion 102b has a width wider than that of the liner main body portion 102a, and is arranged inside the 1 st body flange portion 100b, and one side surface thereof is exposed to the outside.
The 2 nd liner flange portion 102c has a width wider than that of the liner main body portion 102a, and is arranged inside the 2 nd main body flange portion 100c, and one side surface thereof is exposed to the outside.
The metal member, which surrounds the
According to one embodiment, the metal parts may include a 1 st sub-metal part 400 and a 2 nd sub-metal part 402. For example, the metal part may be composed of two sub-metal parts 400 and 402 of the same structure. The sub-metal members 400 and 402 are separate members.
The 1 st sub-metal part 400 may be formed in a single body, and may surround half of the
The 1 st sub-body portion 400a surrounds half of the liner body portion 102a and may have a curved shape.
The 1 st-1 st sub-flange 400b is connected to the end of the 1 st sub-body 400a and may be arranged directly below the 1 st liner flange 102 b. Specifically, the concave curve 410 formed in the center of the 1 st-1 st sub-flange portion 400b surrounds half of the liner body portion 102a directly below the 1 st liner flange portion 102b, and the curvature of the concave curve 410 may be the same as or similar to that of the liner body portion 102 a.
According to one embodiment, the width of the 1 st-1 st sub-flange part 400b is wider than the width of the 1 st liner flange part 102b, and as a result, when the 1 st-1 st sub-flange part 400b surrounds the liner main body part 102a, as shown in fig. 5, the 1 st-1 st sub-flange part 400b supports the 1 st liner flange part 102b and at least a part of the 1 st-1 st sub-flange part 400b can protrude outward of the 1 st liner flange part 102b in the width direction. Wherein the 1 st liner flange portion 102b may be more protruded than the 1 st-1 st sub-flange portion 400b in a length direction.
Only, the 1 st-1 st sub-flange part 400b can directly surround the 1 st liner flange part 102b, but in this case, there is a space between the
And, at least one hole 430 may be formed on the 1 st-1 st sub-flange part 400b, such a hole 430 being a hole for a coupling member to pass through. That is, the coupling member penetrates the hole 110 of the 1 st main body flange portion 100b and the hole 430 of the 1 st-1 st sub flange portion 400b when the pipe is coupled to the pipe.
The 1 st-2 nd sub-flange 400c is connected to the other end of the 1 st sub-body 400a, and may be arranged right below the 2 nd liner flange 102 c. Specifically, the concave curve formed in the center of the 1 st-2 nd sub-flange portion 400c surrounds half of the lining body portion 102a directly below the 2 nd lining flange portion 102c, and the curvature of the concave curve may be the same as or similar to that of the lining body portion 102 a.
According to one embodiment, the width of the 1 st-2 nd sub-flange part 400c is wider than the width of the 2 nd liner flange part 102c, and as a result, in the case where the 1 st-2 nd sub-flange part 400c surrounds the liner body part 102a, as shown in fig. 5, the 1 st-2 nd sub-flange part 400c supports the 2 nd liner flange part 102c and at least a part of the 1 st-2 nd sub-flange part 400c can protrude outward of the 2 nd liner flange part 102c in the width direction. Wherein the 2 nd liner flange portion 102c may be more protruded than the 1 st-2 nd sub-flange portion 400c in the length direction.
Only, the 1 st-2 nd sub-flange part 400c can directly surround the 2 nd liner flange part 102c, but in this case, there is a space between the
Also, at least one hole for passing the coupling member may be formed on the 1 st-2 nd sub-flange part 400 c. That is, the coupling member penetrates the hole of the 2 nd main body flange portion 100c and the holes of the 1 st-2 nd sub flange portions 400c when the pipe fitting and the pipe are coupled.
Sub-metal 2 component 402 may be formed as an integral body surrounding the other half of
The 2 nd sub-body portion surrounds the other half of the liner body portion 102a and may have a curved shape.
The 2 nd-1 st sub-flange portion is connected to the end of the 2 nd sub-body portion, and may be arranged right below the 1 st liner flange portion 102 b. Specifically, the concave curve formed in the center of the 2 nd-1 st sub-flange portion surrounds the other half of the lining body portion 102a directly below the 1 st lining flange portion 102b, and the curvature of the concave curve may be the same as or similar to the curve of the lining body portion 102 a.
According to an embodiment, the width of the 2 nd-1 st sub-flange portion is wider than the width of the 1 st liner flange portion 102b, and as a result, when the 2 nd-1 st sub-flange portion surrounds the liner body portion 102a, the 2 nd-1 st sub-flange portion supports the 1 st liner flange portion 102b and at least a part of the 2 nd-1 st sub-flange portion can protrude outward of the 1 st liner flange portion 102b in the width direction. Wherein the 1 st liner flange portion 102b may be more protruded than the 2 nd-1 st sub-flange portion in the length direction.
However, the 2 nd-1 st sub-flange portion can directly surround the 1 st liner flange portion 102b, but in this case, a space exists between the
Also, at least one hole 432 may be formed on the 2 nd-1 th sub-flange part, and such hole 432 is a hole for a coupling member to pass through. That is, the coupling member penetrates the hole 110 of the 1 st main body flange portion 100b and the hole of the 2 nd-1 st sub flange portion when the pipe fitting and the pipe are coupled.
In addition, the 2 nd-1 th sub-flange part has a multi-maid shape with half cut away, except that the end surfaces 420 and 422 of the concave curve can be connected to the end surfaces 414 and 416 of the 1 st-1 st sub-flange part 400 b. That is, the metal member may surround the
The 2 nd-2 nd sub-flange portion is connected to the other end of the 2 nd sub-body portion, and may be arranged right below the 2 nd lining flange portion 102 c. Specifically, the concave curve formed in the center of the 2 nd-2 nd sub-flange portion surrounds the other half of the lining body portion 102a directly below the 2 nd lining flange portion 102c, and the curvature of the concave curve may be the same as or similar to that of the lining body portion 102 a.
According to an embodiment, the width of the 2 nd-2 nd sub-flange portion is wider than the width of the 2 nd liner flange portion 102c, and as a result, when the 2 nd-2 nd sub-flange portion surrounds the liner body portion 102a, the 2 nd-2 nd sub-flange portion supports the 2 nd liner flange portion 102c and at least a part of the 2 nd-2 nd sub-flange portion can protrude outward of the 2 nd liner flange portion 102c in the width direction. Wherein the 2 nd liner flange portion 102c may be more protruded than the 2 nd-2 nd sub-flange portion in a length direction.
However, the 2 nd-2 nd sub-flange portion can directly surround the 2 nd liner flange portion 102c, but in this case, there is a space between the
And, at least one hole may be formed on the 2 nd-2 nd sub-flange part, the hole being a hole for a coupling member to pass through. That is, the coupling member penetrates the hole of the 2 nd main body flange portion 100c and the hole of the 2 nd-2 nd sub-flange portion when the pipe fitting and the pipe are coupled.
In addition, the 2 nd-2 nd sub-flange part has a multi-maid shape with a half cut away, except that the end surface of the concave curve can be connected to the end surface of the 1 st-2 nd sub-flange part 400 c. That is, the metal member may surround the
In the case of the manufacturing process, the metal member may be formed inside the
At this time, at least one hole other than the hole for coupling the coupling member to the flange portions 400b, 400c, etc. of the metal member may be formed such that the metal member is firmly fixed to the
Also, at least one protrusion may be formed on the metal parts if the bonding is to be more firmly performed.
The reason why the metal member is formed as the two separate sub-metal members 400 and 402 is to arrange the lining 102 inside the metal member. In the case where the metal member is formed in an integral structure, the width of the flange portion 102b or 102c of the
In summary, it is possible to include the sub-metal members 400 and 402 in the
In the case where the metal member does not surround the liner but directly surrounds the liner as a plastic body, when the flange of the pipe and the flange of the pipe are coupled by the coupling member, the pipe may be twisted in a direction opposite to the coupling direction due to the coupling force of the coupling member.
In contrast, in the case where the
Of course, in the case where the body is formed of metal and the liner is arranged inside the body, the pipe is prevented from being twisted even when the pipe is coupled with the pipe, but it is difficult to process the body and the manufacturing unit price may be greatly increased. Also, the pipe can corrode and have a shortened service life.
Therefore, the
The flange portion of the
The foregoing has described that the metal member is composed of the two sub-metal members 400 and 402 having the same shape and arranged symmetrically with each other, but the metal member may be composed of three or more sub-metal members separately. Wherein the inner portion of the sub-metal part lines up the
For example, three sub-metal parts of the same shape, which may be formed to be separated at 120 degree intervals, surround the
However, in consideration of ease of engineering, the metal member is most effectively formed of the two sub metal members 400 and 402.
According to other embodiments, the tubular may not include a liner. That is, the pipe may be composed of a main body and metal parts having a 1 st sub-metal part and a 2 nd sub-metal part, and does not include a liner.
