Description

Technical Field

[0001] The utility model belongs to the technical field of ball valves, and particularly relates to a ball valve. Background Technique

[0002] A ball valve is a valve in which the opening and closing member (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat with surfacing hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels.

[0003] After the ball valve is used for a long time, more impurities will accumulate inside it, which will cause it to be blocked. Therefore, in view of the above situation, there is an urgent need to develop a ball valve that is convenient to disassemble and clean, so as to overcome the deficiencies in current practical applications and meet the current requirements. Summary of the Invention

[0004] The purpose of the utility model is to provide a ball valve that is convenient to disassemble and clean in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A ball valve includes a valve body. A valve ball is arranged inside the valve body. An inlet pipe for water inlet and an outlet pipe for water outlet are arranged on the valve body. It is characterized in that a connecting part communicating with the inside of the valve body is arranged at the lower end of the valve body. The connecting part is communicated with the inlet pipe through a connecting pipe. A filtering device is detachably and fixedly installed on the connecting part. The filtering device consists of an installation part and a filter net. A fixing rod is arranged on the connecting part relative to the filtering device. An opening for the fixing rod to pass through is arranged on the installation part. A positioning mechanism is arranged on the fixing rod. The filtering device is fixedly installed on the connecting part through the positioning mechanism. The positioning mechanism includes a positioning part and a connecting spring. An installation groove for installing the positioning mechanism is arranged on the fixing rod. The positioning part expands and contracts in the installation groove under the action of a return spring to fix the filtering device on the connecting part.

[0006] In the above-mentioned ball valve, one end of the positioning part extends out of the installation groove and abuts against the installation part in the filtering device, and the other end of the positioning part extends into the installation groove and is connected with the connecting spring.

[0007] In the above-mentioned ball valve, a stepped part is arranged on the installation part, and a stepped groove matching with the stepped part is arranged on the connecting part.

[0008] In the above-mentioned ball valve, the connecting pipe is arranged in an L-shaped structure, and the internal channel of the valve ball is arranged in an L-shaped structure.

[0009] In the above-mentioned ball valve, an abutting ring for the filter device to abut against is arranged on the inner wall of the connecting part.

[0010] Compared with the prior art, in this ball valve, the liquid entering the valve ball is filtered by the filter device arranged at the water inlet, avoiding the problem that a large amount of impurities will accumulate inside the ball valve after long-term use, which will cause its blockage.
