Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to an automatic valve for water conservancy irrigation. Background Art

[0002] The delivery of irrigation water is a necessary task in water conservancy and irrigation work. Therefore, it is necessary to use valves to deliver irrigation water in water conservancy and irrigation work. Automatic valves can control the flow of irrigation water and make irrigation work more smoothly.

[0003] Chinese patent authorization application number: CN202122170493.1 provides an easy-to-install automated valve. The solution is to set a left clamping plate and a right clamping plate on the front tightening adjustment device and the rear tightening adjustment device, and then limit the left clamping plate and the right clamping plate by a limit rod. The adjusting rod is rotated to make the left clamping plate and the right clamping plate approach each other under the action of the positive thread groove and the reverse thread groove, which can improve the tightness of the connection between the water pipe and the valve body, and at the same time reduce the difficulty of installation and disassembly of the entire valve, and reduce the workload of the installer.

[0004] The existing automatic valves have certain drawbacks when in use. First, the irrigation water contains certain impurities during the irrigation process, and the automatic valves cannot filter the impurities. This causes the automatic valves to require frequent maintenance, affecting the smooth operation of the automatic valves. For this reason, we propose an automatic valve for water conservancy irrigation. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide an automatic valve for water conservancy irrigation. By setting a filter ring and a positioning rod, the filter ring can perform filtering work at the inlet end and the outlet end of the automatic valve, so that the valve can effectively filter impurities during operation and reduce irrigation blockage. The positioning rod with a T-shaped structure is separated from the clamping block, so that the filter ring can be easily disassembled as a whole, which is used to solve the problem that the automatic valve cannot filter and is easy to be blocked; by setting a movable part and a clamping block, a pair of movable parts and a clamping block are installed at the inner end of the positioning frame, and the movable part and the clamping block contact the clamping groove at the inner end of the positioning rod. The movable part clamps the clamping block at the inner end of the clamping groove under the elastic force, so that the filter ring can be stably installed at the inner end of the valve body; a sealing part is set, and the sealing part allows the valve core to cooperate with the clamping sealing ring to increase the sealing effect of the valve, increase the sealing performance of the valve when it is closed, and reduce fluid leakage.
