Water conservancy water flow control valve

Abstract

The invention discloses a water conservancy water flow control valve. The water conservancy water flow control valve comprises a water inlet pipe, magnetic control valves, shunt pipes and a water outlet pipe. The four shunt pipes are uniformly and fixedly welded to one side of the water inlet pipe. The water outlet pipe is fixedly welded to the ends, far from the water inlet pipe, of the shunt pipes. The magnetic control valves are fixedly mounted in the middles of the shunt pipes. Each magnetic control valve comprises a valve shell, and a valve water inlet is fixedly formed in the center of the side face, close to the water inlet pipe, of the valve shell. According to the water conservancy water flow control valve, liquid passes through the water inlet pipe and is divided into four partsto flow through the four shunt pipes; each shunt pipe is independently controlled by one magnetic control valve so that a user can adjust the quartered water flow. When needing a quarter of water flow, the user just needs to turn on one magnetic control valve; when needing two-fourths of water flow, the user just needs to turn on the two magnetic control valves, and so on. Through the magnetic control valves, the water conservancy water flow control valve is high in turn-on and turn-off speed and high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of flow control valves, in particular to a flow control valve for water conservancy and water flow. Background technique [0002] Flow control valve, also known as 400X flow control valve, is a multi-functional valve that uses high-precision pilot mode to control flow. It is suitable for pipelines that need to control the flow and pressure of the water distribution pipe, keep the predetermined flow constant, limit the excessive flow to a predetermined value, and appropriately reduce the upstream high pressure, even if the pressure upstream of the main valve changes, it will not affect Flow downstream of the main valve. The connection method is divided into flange type and thread type; welding type. The control and adjustment methods are divided into automatic and manual. [0003] However, traditional flow control valves have some disadvantages during use, such as: [0004] Traditional flow control valves...

AI Technical Summary

Problems solved by technology

[0004] Traditional flow control valves are divided into two modes of operation, automatic and manual. However, the opening and closing speeds of the two flow control valves are very slow. When it is necessary to control the water flow in time, the efficiency of the traditional flow control valve is low.

[0005] Most of the traditional flow control valves can only control the flow, but cannot prevent the backflow phenomenon. When the liquid in the pipeline backflows, the traditional flow control valve cannot stop the backflow in time, which may cause safety hazards
