Problems solved by technology

[0002] During the water injection process of the pipeline, the water flow will continue to change with the water pressure. At present, when the water is injected, people will adjust the size of the water flow through the valve, and when the water pressure is high, it will cause damage to the pipeline. When adjusting the flow rate, people need to adjust according to the flow rate of the water flow, which will increase the labor intensity of people. In order to reduce the labor intensity of people, people will set a constant flow rate. When the flow of water flow changes too much, People adjust the valve, which will increase the workload of people

Abstract

The invention relates to a control valve, in particular to a flow control valve, and aims to provide the flow control valve which can prevent a pipeline from being damaged and reduce the labor intensity. According to the technical scheme, the flow control valve comprises a valve body, connecting nuts, a valve seat, a clamping sleeve, a valve pipe, a first piston, a connecting rod, a chuck, a firstcompression spring, supporting legs, a hydraulic oil tank, a first one-way valve and the like. The connecting nuts are arranged at the left and right sides of the valve body, the valve seat is connected to the left side at the bottom in the valve body, and the clamping sleeve is connected between the left side of the top in the valve body and the top of the valve seat. Through a liquid pumping device, the chuck can move downwards to block the water flow, and the blocking of the water flow can be relieved through the upward movement of the chuck, so that the intermittent cutoff of the water flow can be achieved through the cyclic reciprocating operation, the water pressure can be intermittently reduced, the water supply of a pipeline is guaranteed, the pipeline damage caused by the overlarge water pressure can be prevented, and the labor intensity can be reduced.

In order to reduce the labor intensity of people, people will set a constant flow rate. When the flow of water flow changes too much, People adjust the valve, which will increase the workload of people. Contents of the invention [0003] In order to overcome the shortcomings that the pipeline will be damaged when the water pressure is high, and when the flow of the water is adjusted, people need to adjus...
