[0001] The utility model relates to the technical field of globe valves, in particular to a globe valve with a cleaning and filtering effect. Background Technique

[0002] A globe valve is a forced-sealing valve, and its opening and closing member is a plug-shaped valve flap. The sealing surface is a plane or a conical surface. The valve flap moves linearly along the center line of the fluid. The movement form of the valve stem is a rising and falling rod type or a rising and rotating rod type;

[0003] The existing globe valve does not have a filtering mechanism inside, so it does not have a filtering effect. Moreover, if a filtering mechanism is externally added to the surface of the globe valve, some sundries will adhere to the filtering mechanism after long-term use and it is difficult to clean, and the external installation and removal of the filtering mechanism are very inconvenient. Therefore, it is necessary to design a globe valve with a cleaning and filtering effect to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a globe valve with a cleaning and filtering effect to solve the problems put forward in the above background technique.

[0006] One side of the filter plate is rotatably connected with a rotating rod through an opening. The left end of the rotating rod is fixedly installed with a cleaning plate that is used in cooperation with the filter plate. The right end of the rotating rod is fixedly installed with a square rod. A collar is slidably connected to the surface of the water outlet pipe. The right side of the collar is rotatably connected with a rotating sleeve through a bearing member. A square sleeve is fixedly installed on the right side of the inner cavity of the rotating sleeve. The right end of the square rod extends into the inside of the square sleeve.

[0010] Preferably, a sewage pipe is communicated with the left side of the valve body.

[0011] Preferably, a second solenoid valve is provided on the surface of the sewage discharge pipe.

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

[0013] 1. For the globe valve with cleaning and filtering effects, the water can be filtered by setting a filter plate. After the filter plate is used for a long time, the collar can be sleeved on the surface of the water outlet pipe and then the threaded cylinder is rotated.
