Detailed Description

The invention will be further described with reference to preferred embodiments.

As shown in fig. 1 to 3, the small-sized magnetic filtering angle valve comprises an angle valve body 1, wherein a through hole 10 is formed in the tail end of the angle valve body 1 and connected with a magnetic filtering component 2, the magnetic filtering component 2 comprises a visible transparent cover 20, a protective cover 21 for fixing the transparent cover 20 to the tail end of the angle valve body 1, a separable magnetic block 3 is further arranged between the transparent cover 20 and the protective cover 21, a shuttle-shaped flat filter screen 22 is arranged in the transparent cover 20, a visible groove 23 is formed in the protective cover 21, a valve ball 3 is arranged in the angle valve body 1, and a flow guiding layered plate 30 is arranged in the valve ball 3.

The flow direction of the fluid medium of the angle valve has directionality, and the fluid medium enters horizontally from the water inlet end 12 and vertically comes out from the water outlet end 13 at the upper part. Therefore, under the user state, the handle 5 and the valve rod 6 of angle valve set up down, and this structural setting is mostly different with the use custom of prior art valve, because this valve dress is in hanging stove below, and the water trend of cominging in and going out is with hanging stove cooperation, and hanging stove liftoff has certain height for handle 5 reasonable in design down.

The through hole 10 and the water inlet end 12 are in the same axial position.

The magnetic block 3 is arranged between the transparent cover 20 and the protective cover 21, and the magnetic block 3 is easy to demagnetize under a high-temperature medium. The magnetic block 3 in the structure can be taken out, and the magnetic block 3 is convenient to replace due to the independently designed structure. In the drawing, the magnetic block 3 is arranged at the middle part of the leftmost end, and can also be arranged at the bottom part and is positioned between the transparent cover 20 and the protective cover 21.

The transparent cover 20 is made of transparent and high-temperature-resistant plastic material such as PPSU, PA12, PSU, etc., and may also be made of glass material. The transparent cover 20 and the protective cover 21 are made of non-metal materials, so that the heat conduction is slow, and the scalding of an operator can be prevented when the operator touches the transparent cover. And the transparent cover 20 and the protective cover 21 are separated from the heat source fluid medium, so that the heat insulation effect is better, and the disassembly, assembly and maintenance are safe.

As shown in fig. 3 to 5, the main plate 31 of the flow guiding and laminating plate 30 in the valve ball is composed of a left horizontal portion 32 and a right upward inclined portion 33, and divides the flow path into an upper flow path 34 and a lower flow path 35 in the valve ball 3. The design of the upward inclined part 33 makes the inflow water flow large, and the flow passage has no convex part, the medium flows smoothly, and the noise is greatly reduced.

The right end of the flow guiding layering plate 30 is also provided with a limiting ring 36 matched with the inner wall of the valve ball 3. The limiting ring 36 makes the diversion layering plate 30 concentric with the valve ball 3, and is also provided with a limiting strip 38 for limiting the front, back, left and right rotation of the diversion layering plate 30. The flow guiding and layering plate 30 in the valve ball 3 can also be formed by injection molding.

The left end face of the flow guiding layered plate 30 is provided with an arc structure 37, and the arc structure 37 does not protrude out of the excircle of the valve ball 3, so that the valve ball 3 cannot be clamped when rotating, and the size of the valve ball 3 is as large as the excircle of the valve ball as possible. The right end face of the filter screen 22 is provided with an inner concave arc structure 24, and the inner concave arc structure 24 is matched with the arc structure 37 and is provided with a movable gap structure 4. The clearance structure 4 may be as small as possible to prevent fluid medium from entering the upper flow passage 34 directly without passing through the filter screen 22. However, the existence of the movable gap structure 4, the direction of which is vertical, is different from the flow direction of the fluid medium, has little influence on the filtration, and in case of blockage of the filter screen 22, the movable gap structure can open the channel to prevent the channel from being blocked, thereby having the existing function.

As shown in fig. 2 and 3, a horizontal limiting block 25 is arranged on the outer wall of the transparent cover 20 and is matched with the horizontal limiting groove 11 of the angle valve body 1; the inner wall of the transparent cover 20 is provided with a filter screen limiting groove 27. The horizontal limiting block 25, the horizontal limiting groove 11 and the filter screen limiting groove 27 are symmetrically arranged on two sides, and play a role in limiting and positioning. The filter screen of the angle valve has directionality, and the arrangement of the magnetic block 3 is also elaborated, so that the transparent cover 20 needs to be positioned.

As shown in fig. 5, the filter screen 22 is surrounded by a flexible frame 26 which can be sealed and attached to the inner wall of the transparent cover 20. The filter screen 22 is an unconventional structure, has a plane structure and an arc-shaped edge, and is obliquely arranged in the transparent cover 20, so that the impurities 9 can fall below the transparent cover. The prior art filter screen structure is mostly cylindrical or rectangular, which is different from the invention.

The protective cover 21 is provided with a visual groove 23, and the condition of the impurities 9 can be checked through the transparent cover 20. In the dismounting maintenance process, the valve ball 3 is required to be closed firstly through the handle 5, the protective cover 21 is screwed out and the magnetic block 3 is taken out, iron impurities 9 adsorbed near the magnetic block 3 fall in the transparent cover 20, the transparent cover 20 is pulled out, the impurities 9 are poured out, and meanwhile the filter screen 22 can be pulled out for washing. When the angle valve is installed back, the filter screen 22 is installed in the filter screen limiting groove 27 of the transparent cover 20, the horizontal limiting block 25 of the transparent cover 20 is matched and positioned with the horizontal limiting groove 11 of the angle valve body 1, and the protective cover 21 is screwed tightly.

According to the magnetic filtering angle valve with the novel structure, the independent visible impurity storage cavity is adopted, so that the pipeline is prevented from being blocked by impurities, and the maintenance and the removal are more thorough; the special valve ball structure of reposition of redundant personnel for when fluid medium 90 degrees turns, the flow resistance is little, and the noise is little, and it is smooth and easy to flow. The filtering angle valve is small and reasonable in overall structure, is particularly suitable for use occasions of wall-mounted furnaces, and has market popularization value.
