It does not require an external power supply or gas source. It is usually used in unmanned places without electricity or gas, and has the effect of convenient operation and saving manpower.

[0003] After searching the Chinese patent number: CN114776860B, a self-operated regulating valve with corrosion resistance function was found. The design scheme uses the linkage design of the flexible tube body and the nozzle, so that the pump body can complete the cleaning of the outside of the pump body without external power. However, the nozzle is a fixed structure, and it does not fully clean the outside of the pump body. Dust is easily accumulated on the outside of the pump body, resulting in poor corrosion resistance. Now there is an urgent need for a self-operated regulating valve with corrosion resistance to solve the above problems. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a self-operated regulating valve with corrosion resistance, comprising a ventilation pipe, a valve body, an exhaust hole, a sealing base, a movable seat, a positioning slider and an air jet hole, a flange base is installed on the upper end surface of the valve body, and lifting slide bars are arranged on the left and right sides of the upper end surface of the flange base, a ventilation pipe is fixed on the upper end surface of the lifting slide bar, a hydraulic cavity connecting flange is fixed on the upper end surface of the ventilation pipe, a hydraulic cavity is fixedly connected to the upper end surface of the hydraulic cavity connecting flange, a liquid inlet pipe is connected to the right end surface of the valve body, and a liquid discharge pipe is connected to the left end surface of the valve body;

[0006] A one-way air inlet pipe is fixed to the lower end surface of the hydraulic cavity, a liquid passage pipe is connected between the upper end surface of the liquid inlet pipe and the hydraulic cavity and a tail end of the liquid passage extends into the one-way air inlet pipe, a flexible pipe body is arranged on the outer side of the annular surface of the one-way air inlet pipe, a sealing base is fixed to the lower end surface of the ventilation pipe, an exhaust hole is provided inside the sealing base, a movable seat is movably connected to the sealing base, positioning sliders are fixed to both left and right end surfaces of the movable seat, and an air jet hole is provided inside the movable seat.

[0007] Furthermore, a sealing gasket is provided between the liquid passage pipe and the liquid inlet pipe, and a sealing gasket is provided between the liquid passage pipe and the hydraulic cavity.

[0008] Furthermore, a sealing gasket is provided between the flexible pipe body and the one-way air intake duct.

This design enables the movable seat 14 to rotate and drive multiple groups of injection holes 16 to clean the outside of the pump body without external power, so that the cleaning is more comprehensive, dust is not easily accumulated on the outside of the pump body, and the corrosion resistance of the pump body is improved.

[0023] As the first embodiment of the utility model: a sealing gasket is provided between the liquid pipeline 6 and the liquid inlet pipeline 7, a sealing gasket is provided between the liquid pipeline 6 and the hydraulic cavity 1, and a sealing gasket is provided between the flexible pipe body 11 and the one-way air inlet pipeline 10. This design allows the water flow of the inlet liquid to enter the hydraulic cavity 1 through the liquid pipeline 6 when the flow rate is large, so that the hydraulic cavity 1 is gradually filled with liquid;

[0024] A vent hole is provided inside the ventilation pipe 3, the specifications of the vent hole match those of the exhaust hole 12, and the two overlap to form an exhaust cavity. This design allows the flexible tube body 11 to expand after being filled with liquid, so that the air inside the ventilation pipe 3 flows into the exhaust hole 12 through the vent hole;

[0025] A circular sliding groove is provided inside the sealing base 13, and the inner diameter of the circular sliding groove is equal to the outer diameter of the movable seat 14, and the two can fit and slide together.

[0026] As a second embodiment of the utility model: when the water flow rate of the incoming liquid is large, the liquid enters the hydraulic cavity 1 through the liquid passage pipe 6, so that the hydraulic cavity 1 is gradually filled with liquid, and the flexible tube body 11 expands after being filled with liquid, so that the air inside the ventilation pipe 3 flows into the exhaust hole 12 through the vent hole, and the air in the exhaust hole 12 flows into the jet hole 16. Since the jet hole 16 is set as an inclined hole, it can drive the movable seat 14 to rotate inside the sealing base 13. The positioning slider 15 is connected with the positioning slide groove by sliding, so that the rotation of the movable seat 14 inside the sealing base 13 is more stable, so that the jet hole 16 can move around the pump body, so that dust is not easy to fall on the outside of the pump body, thereby improving the corrosion resistance of the pump body.
