Description

Technical Field

[0001] This utility model relates to the field of three-way ball valve technology, specifically an anti-clogging three-way fixed ball valve. Background Technology

[0002] A three-way ball valve is a type of valve that controls the flow of media between three pipes. By rotating the ball, it can achieve the functions of splitting, merging, reversing, or cutting off the flow of media. It is widely used in industries such as petroleum, chemical, metallurgy, power, and water treatment.

[0003] When liquids are transported via a three-way ball valve, impurities in the liquid can accumulate in the valve cavity when they enter the ball. This significantly reduces the efficiency of medium flow, causing abnormal system pressure or flow fluctuations, affecting the stability of the process. Jamming between the ball and the valve seat can prevent the valve from switching flow direction or closing completely, affecting system control accuracy. Regular cleaning is necessary, but disassembly is cumbersome. Therefore, we propose an anti-clogging three-way fixed ball valve. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging three-way fixed ball valve to solve the problems mentioned in the background art.

[0005] A clog-resistant three-way fixed ball valve includes a ball with a valve seat rotatably connected within it. The ball has an inlet, and a filter unit is located at the inlet for filtering the liquid. A discharge unit is located on the outer wall of the ball for discharging impurities. The filter unit is connected to the discharge unit. The filter unit includes:

[0006] A filter frame, located in the liquid inlet, is used to filter the liquid;

[0007] A guide frame, which is installed on the front of the filter frame, is used to guide the liquid flow;

[0008] The mounting base is fixedly connected to the liquid inlet, and the filter frame and guide frame are fixed to the filter frame and guide frame by bolts.

[0009] Preferably, the guide frame is tapered to store impurities in the liquid within the filter frame.

[0010] Preferably, a connecting seat is fixedly connected to the bottom of the filter frame, and the connecting seat is used to connect the discharge unit and the filter frame.

[0011] Preferably, the discharge unit includes a collecting pipe, which is inserted into the sphere, and one end of the collecting pipe is connected to the connecting seat.

[0012] Preferably, the outer peripheral wall of the collecting pipe is provided with a fixing pipe, which is fixedly connected to the outer wall of the sphere.

[0013] Preferably, a sealing seat is installed on the bottom end face of the fixing tube, and the sealing seat is used to seal the fixing tube.

[0014] Preferably, the outer wall of the fixed tube is provided with an air inlet.

[0015] By adopting the above technical solution, impurities can be collected and removed periodically, effectively preventing impurities from entering between the valve seat and the ball, and facilitating quick and easy processing of impurities.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this anti-clogging three-way fixed ball valve,

[0017] The system is equipped with a sphere, within which a valve seat is rotatably connected. An inlet is located on the sphere, and a filter unit is installed at the inlet to filter the liquid. A discharge unit is located on the outer wall of the sphere. When liquid enters the sphere through the inlet, it passes through a guide frame and enters the filter frame for filtration. Impurities are collected between the filter frame and the guide frame, and simultaneously collected by the discharge unit. This discharge unit periodically removes impurities, effectively preventing them from entering the valve seat and causing blockage. It also effectively prevents impurities from remaining between the valve seat and the sphere, which could lead to wear or jamming of the valve seat and affect the normal opening and closing of the sphere.
