Civilian irrigation water stop valve

Abstract

The invention discloses a civilian irrigation water stop valve, and belongs to the field of agricultural irrigation. The civilian irrigation water stop valve is composed of a connection pipe head, a thread, a cylinder body, locating base plates, bolts, a filtering cover, filtering holes, a sliding groove, a rotary water drainage knob, a rubber pad, a locating column, a nylon rope, a valve, a stop block, a supporting rod, a universal joint, an installation protrusion block, a rotating shaft and a rope lug. Through cooperation among the valve, the supporting rod and the stop block, water leakage is avoided in the irrigation process, the water release work can be completed by rotating the rotary water drainage knob after irrigation is completed, the operation is efficient, convenient, fast and easy, the problem that leakage occurs in traditional structures because of wrong placement positions of valves can be avoided even if a water pump stops drawing water in the middle, the device modification structure is simple, the operation is easy and the popularization performance is good.

Description

technical field [0001] The invention relates to a civil irrigation water stop valve, in particular to a civil irrigation water stop valve which can facilitate water discharge after use, and belongs to the field of agricultural irrigation. Background technique [0002] Now with the development of the country's agricultural water conservancy construction, part of the irrigation of rural fields has realized automatic agricultural irrigation, but a considerable part of it uses traditional agricultural irrigation. The traditional irrigation mode is to use self-priming pumps to transfer irrigation water through nylon hoses. Pumping from the river to the farmland for irrigation, the end of the nylon hose pumping water is often equipped with an irrigation water stop valve. When watering the ground, because the airtightness of the agricultural equipment is not good enough, the water is often poured into the nylon water pipe through a self-priming pump first. Then, the self-priming pu...

[0002] Now with the development of the country's agricultural water conservancy construction, part of the irrigation of rural fields has realized automatic agricultural irrigation, but a considerable part is using traditional agricultural irrigation. The traditional irrigation mode is to use self-priming pumps to transfer irrigation water through nylon hoses Pumping from the river to the farmland for irrigation, the end of the nylon hose pumping water is often equipped with an irrigation stop valve. When watering the ground, because the airtightness of the agricultural equipment is not good enough, the water is often poured into the nylon water pipe through a self-priming pump first. Then, the self-priming pump is driven by the internal combustion engine to pump water. During the irrigation process, the water in the nylon water pipe often leaks back into the river. This is usually caused by the incorrect valve position of the irrigation water stop valve, and it is disassembled after the irrigation. Nylon water pipes often need to be drained. During the draining process, since there is a large amount of water stored in the nylon water pipe, it is often necessary to place both ends of the nylon pipe at the same position, and then use a tool to pry open the valve to drain and drain the water. Finally, put the nylon water pipe back. This process is very cumbersome, and even splashes water on the body and wets the clothes. This process is often labor-intensive, and it is easy to cause damage to the irrigation water stop valve.
