[0002] With the implementation of the country's strict water resources management system, a water-saving society, especially agricultural water-saving projects, will develop rapidly. Pipeline irrigation, as the main form of agricultural water-saving projects, is particularly suitable for field crop water-saving projects. The water supply valve, as a key component of field water use, is the most critical ancillary facility in irrigation projects.

[0003] Existing farmland irrigation water supply valves are generally external pressure water stop, butterfly valve or gate valve type. The existing technology generally sets a water outlet on one side of the valve body, a valve stem on the top, and a water stop valve at the lower end of the valve stem. The manufacturing materials are mainly cast iron, steel and fiberglass, etc., which leads to problems such as large investment, easy theft, easy rust and poor sealing performance. In addition, since the water valve needs to be opened and closed with the help of electricity, it has the problem of poor practicality. Therefore, we urgently need a farmland irrigation water supply valve with upper and lower body threaded connections to solve the above problems. Utility Model Content
