Description

Technical Field

[0001] The utility model relates to the field of pressure reducing valves, in particular to a pressure reducing valve that prevents blockage. Background Technique

[0002] A pressure reducing valve is a valve that reduces the inlet pressure to a required outlet pressure through adjustment and relies on the energy of the medium itself to automatically maintain the stability of the outlet pressure. From the perspective of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction. Then, relying on the adjustment of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain error range.

[0003] At present, the application environment of pressure reducing valves is mainly for the transportation of gases and liquids. The current pressure reducing valves have a relatively simple structure, and their main function is to control the pressure of gases and liquids. However, since gases and liquids may carry particulate matter, if not cleaned, it will cause blockage of the pressure reducing valve, and in severe cases, it will cause damage to the pressure reducing valve. Therefore, we propose a pressure reducing valve that prevents blockage to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pressure reducing valve that prevents blockage to solve the problems raised in the above background technique.

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

The inner ring of the sealing bearing is fixedly connected to a spiral conveyor rod. A rotating motor is fixedly connected to the left side surface of the pressure reducing valve body. The output end of the rotating motor is fixedly connected to the left end of the spiral conveyor rod.

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

[0013] By providing a pressure reducing valve body, a sealing bearing, a screw conveyor rod and a rotating motor, the rotation of the rotating motor can conveniently drive the screw conveyor rod to rotate within the inner ring of the sealing bearing, and the rotation of the screw conveyor rod can assist in conveying the particulate matter accumulated inside the pressure reducing valve body, avoiding the situation of particulate matter blocking the pressure reducing valve body. At the same time, in cooperation with the pressure reducing pipe, the adjusting rod, the connecting rod and the scraper, it can not only conveniently adjust the pressure of the pressure reducing valve body, but also clean the inner wall of the pressure reducing valve body, avoiding the situation that particulate matter adheres to the inner wall of the pressure reducing valve body and affects the pressure control, thereby improving the functionality of the device.
