Background

As is known, a ball valve is a valve in which the closure member (ball) is driven by the valve stem and rotates about the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline. The ball valve is divided into: pneumatic ball valves, electric ball valves, manual ball valves.

The patent numbers are: the invention of CN103047463B discloses a multi-style ball valve, which comprises a body, a valve ball, a valve rod, a handle, two anti-diarrhea rings, a rotation limiting sleeve and a connecting sleeve. The body is provided with a flow passage and a mounting hole; the anti-diarrheal rings and the valve ball are positioned in the flow channel, and the valve ball can be rotatably positioned between the two anti-diarrheal rings; the valve rod is connected with the valve ball, the handle is connected with the valve rod, and the handle rotates to drive the valve ball to rotate through the valve rod so as to control the flow passage; the flow passage is provided with a front section and a rear section, and a forward step surface is arranged between the front section and the rear section; the connecting sleeve is connected with the front section so as to position the two antidiarrheal rings and the valve ball between the end of the connecting sleeve and the stepped surface; the inner hole of the connecting sleeve and the inner hole of the rear section are set to be the same connecting structure which can be connected with an external pipeline. It has the following advantages: the inner hole of the connecting sleeve and the inner hole of the rear section are set to be the same connecting structure capable of being connected with an external pipeline, so that the ball valve and the external pipeline are convenient to connect, the ball valve and the external pipeline are firm and reliable to connect, the sealing performance is high, parts are few, and the cost is low.

However, the present invention still has disadvantages, for example, when in use, the circulation of the ball valve can be controlled by directly pushing the handle, and the circulation inside the ball valve can be changed by touching the handle by a worker unintentionally, which hinders the circulation inside the ball valve, and when the ball valve is connected with a pipeline, the sealing effect of the connection is not good due to the direct threaded connection, and so on, so that a solution capable of alleviating the above problems is urgently needed.

At this time, when the push handle 514 is pressed downward, the push handle 514 drives the gear shaft 511 and the hollow tube 57 to move downward, when the hollow tube 57 drives the moving block 510 to move to one side of the fixed plate 54, the fixed plate 54 presses the moving block 510 toward the inside of the moving groove 58, the moving block 510 compresses the spring 59 inward, when moving to the lower end of the fixed plate 54, the spring 59 bounces outward, the moving block 510 moves to the lower end of the fixed plate 54, the gear shaft 511 moves to the lower end of the internal gear tube 515, if the push handle 514 is rotated at this time, the gear shaft 511 rotates on the inner side of the rotating shaft 51 of the lower end of the internal gear tube 515, the gear shaft 511 rotates on the lower end of the internal gear tube 515, the gear shaft 511 does not drive the rotating shaft 51 to rotate, at this time, the push handle 514 cannot change the circulation inside, when the ball valve is to be closed, the push handle 514 is, so that the moving block 510 presses the spring 59, the moving block 510 moves to the lower end of the second moving ring 55, and is pulled up to the push handle 514, so that the moving block 510 compresses the spring 59 inwardly through the second moving ring 55 and the fixed plate 54, and moves to the upper end of the fixed plate 54, so that the gear shaft 511 moves to the inside of the internal gear tube 515, then the push handle 514 is rotated, because the inner gear tube 515 is meshed with the gear shaft 511, the rotation of the push handle 514 causes the gear shaft 511 to rotate the internal gear tube 515 about the fixed shaft 513, which in turn causes the rotation of the rotation shaft 51, causing the rotation shaft 51 to rotate in the inside of the bearing 56, and the rotation of the control ball 2 is carried out, so that the ball valve is closed, the gear shaft 511 is moved to the lower end of the internal gear tube 515 by pressing the push knob 514 downward, the purpose of preventing the staff from rotating the push handle 514 to close the ball valve in an unintentional situation can be achieved.

The outside of control ball 2 and the inboard swing joint of connecting ball 1, the outside of connecting ball 1 and the inboard fixed connection of protection tube 3.

The protective effect of the connecting ball 1 can be achieved by the protective tube 3.

The working principle is as follows:

when in use, the first threaded rod 46 is firstly rotated, because the first threaded rod 46 is in threaded connection with the first nut 47, the first threaded rod 46 is rotated to enable the first threaded rod 46 to move outside the first nut 47, the second fixing ring 44 and the first fixing ring 42 are fixed together with the first nut 47 through the first threaded rod 46, the second nut 414 is fixed, the second threaded rod 412 is rotated to enable the fixture block 410 to rotate in the fixing rod 49, because the second nut 414 is in threaded connection with the second threaded rod 412, the second threaded rod 412 is rotated to enable the second threaded rod 412 to move upwards, the second threaded rod 412 drives the first moving ring 48 to move upwards through the fixing rod 49, the first moving ring 48 is enabled to press the sealing strip 43 upwards, the sealing strip 43 is enabled to close a gap between the first fixing ring 42 and the connecting pipe 41, the first moving ring 48 is enabled to press the sealing strip 43 by rotating the second threaded rod 412, the purpose of sealing the gap between the first fixing ring 42 and the second fixing ring 44 can be achieved, and the problem of poor sealing effect is effectively solved; at this time, when the push handle 514 is pressed downward, the push handle 514 drives the gear shaft 511 and the hollow tube 57 to move downward, when the hollow tube 57 drives the moving block 510 to move to one side of the fixed plate 54, the fixed plate 54 presses the moving block 510 toward the inside of the moving groove 58, the moving block 510 compresses the spring 59 inward, when moving to the lower end of the fixed plate 54, the spring 59 bounces outward, the moving block 510 moves to the lower end of the fixed plate 54, the gear shaft 511 moves to the lower end of the internal gear tube 515, if the push handle 514 is rotated at this time, the gear shaft 511 rotates on the inner side of the rotating shaft 51 of the lower end of the internal gear tube 515, the gear shaft 511 rotates on the lower end of the internal gear tube 515, the gear shaft 511 does not drive the rotating shaft 51 to rotate, at this time, the push handle 514 cannot change the circulation inside, when the ball valve is to be closed, the push handle 514 is, so that the moving block 510 presses the spring 59, the moving block 510 moves to the lower end of the second moving ring 55, and is pulled up to the push handle 514, so that the moving block 510 compresses the spring 59 inwardly through the second moving ring 55 and the fixed plate 54, and moves to the upper end of the fixed plate 54, so that the gear shaft 511 moves to the inside of the internal gear tube 515, then the push handle 514 is rotated, because the inner gear tube 515 is meshed with the gear shaft 511, the rotation of the push handle 514 causes the gear shaft 511 to rotate the internal gear tube 515 about the fixed shaft 513, which in turn causes the rotation of the rotation shaft 51, causing the rotation shaft 51 to rotate in the inside of the bearing 56, and the rotation of the control ball 2 is carried out, so that the ball valve is closed, the gear shaft 511 is moved to the lower end of the internal gear tube 515 by pressing the push knob 514 downward, the purpose of preventing the staff from rotating the push handle 514 to close the ball valve in an unintentional situation can be achieved.
