Description

Technical Field

[0001] The utility model relates to the field of ball valves, in particular to a ball valve with an anti-blocking function. Background Technique

[0002] A ball valve is a valve whose closing part is driven by a valve stem and rotates around the axis of the ball valve. It can be used for the regulation and control of fluids. The ball valve is mainly used in pipelines to cut off, distribute and change the flow direction of the medium. It only needs a 90-degree rotation operation and a very small rotational torque to close tightly. The ball valve is most suitable for use as a switch and a cut-off valve.

[0003] At present, the liquid flowing through the ball valve will carry impurities. After long-term use, the impurities are likely to accumulate between the ball valve and the valve body. However, the current ball valve does not have an anti-blocking structure. Subsequently, the blockage of impurities inside the ball valve will affect the opening and closing operation and the sealing performance of the ball valve. For this reason, we propose a ball valve with an anti-blocking function to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a ball valve with an anti-blocking function to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A ball valve with an anti-blocking function includes a valve housing. The right end of the valve housing is fixedly communicated with a connecting pipe. The right end of the connecting pipe is fixedly communicated with a filtering pipe. The outer surface of the filtering pipe is threadedly connected with a first sealing cover. The upper surface of the first sealing cover is fixedly installed with a driving cover. The inner top wall of the driving cover is fixedly installed with a driving motor. The upper surface of the first sealing cover is fixedly inlaid with a first bearing. The inner ring of the first bearing is fixedly connected with a rotating rod. The output end of the driving motor is fixedly connected with the top end of the rotating rod. The inner ring of the filtering pipe is fixedly installed with a filter net. The outer surface of the rotating rod is fixedly connected with a plurality of cleaning brush plates. The upper surface of each cleaning brush plate is in contact with the bottom surface of the filter net. Two water passing holes are opened on the outer surface of the filtering pipe. A valve ball is installed on the inner wall of the valve housing. A controller is fixedly installed on the outer surface of the valve housing.

[0007] In a further embodiment, the outer surface of the filter net is fixedly inlaid with a second bearing. The bottom end of the rotating rod penetrates through the second bearing and extends below the second bearing.

[0008] In a further embodiment, the outer surface of the filtering pipe is threadedly connected with a second sealing cover. The bottom end of the second sealing cover is fixedly connected with a rotating plate.

[0009] In a further embodiment, an annular sealing gasket is fixedly connected to the inner bottom wall of the second sealing cover, and the upper surface of the annular sealing gasket is in contact with the bottom end of the filter pipe.

[0010] In a further embodiment, a water outlet pipe is fixedly communicated with the left end of the valve housing, and a water outlet flange is fixedly communicated with the left end of the water outlet pipe.

[0011] In a further embodiment, a water inlet pipe is fixedly communicated with the right side surface of the filter pipe, and a water inlet flange is fixedly communicated with the right end of the water inlet pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the filter screen arranged inside the filter pipe, the present utility model can filter the flowing water body, block the impurities in the water body at the bottom of the filter screen, and avoid the problem of blockage inside the valve housing. By removing the second sealing cover and simultaneously driving the rotation of the rotating rod and the cleaning brush plate by the driving motor, the bottom of the filter screen can be cleaned, thereby achieving the effect of self-cleaning of the filter screen. Thus, the ball valve has an anti-blocking structure, ensuring the opening and closing operation and sealing performance of the ball valve. BRIEF DESCRIPTION OF THE DRAWINGS

The inner ring of the first bearing 7 is fixedly connected to a rotating rod 8. The output end of the driving motor 6 is fixedly connected to the top end of the rotating rod 8. A filter screen 9 is fixedly installed in the inner ring of the filtering pipe 3. A plurality of cleaning brush plates 11 are fixedly connected to the outer surface of the rotating rod 8. The upper surface of each cleaning brush plate 11 is in contact with the bottom surface of the filter screen 9. Two water passing holes 14 are formed in the outer surface of the filtering pipe 3. A valve ball 18 is installed on the inner wall of the valve housing 1. A controller 21 is fixedly installed on the outer surface of the valve housing 1. Through the filter screen 9 and the two water passing holes 14 arranged inside the filtering pipe 3, the flowing water body can be filtered. The impurities in the water body will be blocked at the bottom of the filter screen 9, avoiding the problem of blockage inside the valve housing 1.

[0023] In a further embodiment, a second bearing 10 is fixedly inlaid on the outer surface of the filter screen 9. The bottom end of the rotating rod 8 penetrates through the second bearing 10 and extends below the second bearing 10.

[0025] The working principle of the present utility model is as follows: First, it is connected and installed with a pipeline through the water inlet flange 13 and the water outlet flange 20. Then, the driving motor 6 is connected to a power source. Subsequently, water will flow inside the filter pipe 3 and be filtered through the filter net 9. Impurities in the water can be blocked at the bottom of the filter net 9. Subsequently, when controlling the water flow, the problem of blockage inside the valve housing 1 can be avoided. When cleaning the bottom of the filter net 9, remove the second sealing cover 16 and start the driving motor 6 to rotate, which can drive the rotating rod 8 and the cleaning brush plate 11 to rotate, enabling the bottom of the filter net 9 to be cleaned and the impurities to flow downward.
