Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to an automatic pressure regulating valve for sewage treatment. Background Art

[0002] An automatic pressure regulating valve is a device used to automatically adjust and maintain stable fluid pressure. It is usually composed of a valve body, a valve core, a spring and a control element. The working principle of the automatic pressure regulating valve is to sense changes in medium pressure and adjust the opening degree of the valve core to achieve a set pressure value. When the medium pressure exceeds the set value, the valve core is pushed to close the valve; when the medium pressure is lower than the set value, the spring pushes the valve core to open the valve, allowing the medium to flow and increase the pressure to keep the pressure in the system stable.

[0003] The existing Chinese patent publication number CN220361596U is an automatic pressure regulating valve for sewage treatment, which includes a valve body, a pressure gauge is installed in the middle of the front end face of the valve body, a fixing plate is equidistantly welded to one side of the outer surface of the pressure gauge, a fixed guide rail is fixedly installed between one end of the inner wall of the fixing plate and the outer surface of the pressure gauge, a rotating groove is opened in the middle of the top end of the fixed guide rail, a sliding part is movably installed inside the rotating groove, a placement rack is welded in the middle of the top end of the sliding part, a placement slot is opened in the middle of the top end of the placement rack, a sliding block is movably installed inside the placement slot, a support plate is installed on one side of the sliding block through the outside of the placement rack, and a cleaning brush is welded to the middle of the bottom end of the support plate.

[0004] Another problem with the above device is that when the glass cover installed on the outside of the pressure gauge is not parallel to the outside of the pressure gauge, the outer edge of the pressure gauge will be relatively protruding. When the cleaning brush is recovered into the placement rack, the cleaning brush will contact the raised outer edge of the pressure gauge, causing the dust on the cleaning brush to fall back to the outside of the pressure gauge.
