Description

Technical Field

[0001] The utility model relates to the technical field of check valves, in particular to a sewage pipe check valve. Background Art

[0002] A check valve is a valve with a circular disc as the opening and closing part. It blocks the backflow of the medium by its own weight and the pressure of the medium. It is an automatic valve, also known as a non-return valve, one-way valve, reflux valve or isolation valve. The disc movement mode is divided into lifting type and swing type. When discharging sewage, a check valve is required to prevent the backflow of sewage in the sewage pipe.

[0003] After searching the Chinese patent "Sewage Pipe Check Valve", the publication number is "CN219994473U". This patent fixes the first port of the valve core tube to the first port of the cylinder body through a pressure cover, and movably connects the second port of the valve core tube to the water stop head, and connects the second port of the cylinder body to the installation port, thereby realizing a sewage pipe check valve with a simple structure and reliable water stop. The installation is simpler and the use is more convenient. However, when the device discharges sewage, impurities in the sewage are easily blocked at the valve port, and it is inconvenient to clean the impurities blocked at the valve port, resulting in poor anti-backflow effect of the check valve.

[0004] Therefore, a sewage pipe check valve is proposed to solve the above problems. Utility Model Content

[0008] Preferably, two compression springs are arranged between the cleaning plate and the mounting block. When the valve port is closed, the cleaning plate cooperates with the compression springs to move into the sealing plate to prevent a gap from appearing at the valve port.

[0009] Preferably, the inner wall of the valve body is rotatably connected to a cleaning ring, the outer wall of the cleaning ring is fixedly connected to a plurality of evenly distributed tooth blocks, and one side of the cleaning ring is meshingly connected to a gear, which can drive the cleaning ring to rotate to prevent impurities from accumulating at the valve port.

[0010] Preferably, a second turbine is rotatably connected to one side of the inner wall of the valve body, and one end of the second turbine is fixedly connected to a gear, so as to drive the cleaning ring to rotate.

[0011] Preferably, a coil spring is arranged between the sealing plate and the valve body, and a protective tube is arranged on the outer wall of the coil spring to protect the coil spring and prevent the spring from being damaged during long-term use.

[0012] Preferably, the filter assembly includes a filter tube arranged at one end of one of the conduits, the inner wall of the filter tube is provided with two filter plates, and an activated carbon adsorbent is arranged between the two filter plates, which can filter impurities in the sewage and prevent the impurities from being blocked at the valve port.

[0014] The beneficial effects of the utility model are:

[0015] By setting up an anti-clogging mechanism, when sewage is discharged, the sealing plate moves upward by the impact force of the water flow to discharge the sewage. When the sewage is discharged, it is driven by the first turbine and the second turbine to rotate. The first turbine cooperates with the mounting block to drive the cleaning plate to rotate, which can prevent impurities from adhering to the sealing plate and improve the sealing performance of the valve port. The second turbine drives the cleaning ring to rotate through the cooperation of the gear and the tooth block to prevent impurities from being blocked in the valve port and prevent the device from backflowing. The sealing plate can seal the valve port through the coil spring, and the protective tube can protect the coil spring to increase the service life of the coil spring, which can prevent impurities from being blocked at the valve port, facilitate quick cleaning of impurities, and prevent sewage from flowing back.

[0016] By setting up a filter assembly, when sewage is discharged, the two filter plates on the inner wall of the filter tube cooperate with the activated carbon adsorbent to filter impurities in the sewage to prevent impurities from being blocked at the valve port, thereby improving the sealing performance of the device. The filter tube is connected to one of the conduits through a fixed sleeve, and the filter tube can be quickly installed and disassembled. The sealing ring can improve the sealing effect between the filter tube and the conduit, and can filter impurities in the sewage to prevent impurities from being blocked at the valve port.
