Embodiment

[0031] like figure 1 and figure 2 As shown, the embodiment of the present invention discloses a hydraulic control valve with hydraulic control opening pressure, which is used for hydraulic control, and is especially suitable for controlling water flow and water pressure in river dams. The hydraulic control valve with hydraulic control opening pressure includes: The valve body 10, the valve core 20, the water pressure control assembly and the cover; specifically, the valve body 10 has a water inlet 13 and a water outlet 14, and a stopper 11 is formed inside the valve body 10, and the stopper 11 is provided with a The guide hole 12 that communicates with the water inlet 13 and the water outlet 14; the valve core 20 blocks the guide hole 12 by moving to cut off the water inlet 13 and the water outlet 14, or moves away from the guide hole 12 to make the water inlet 13 and the water outlet 14 cut off. The water outlet 14 is turned on; the water pressure control assembly is used t...

Abstract

The invention discloses a hydraulic control valve for hydraulically controlling opening pressure, which is used for hydraulic control. A valve core; and a water pressure control assembly. Due to the fact that the water pressure control assembly is arranged in the valve body of the hydraulic control valve capable of hydraulically controlling the opening pressure, the opening pressure of water corresponding to the valve element can be controlled by setting the elastic coefficient and the compression amount of the spring. And the compression amount can be changed by rotating the adjusting nut, so that the preset pressure is changed, and the opening pressure of the valve element is adjusted. Pressure water can be introduced into the control port, after entering the control cavity, the pressure water pushes and abuts against the valve element through the bag wall, and the pressure water and the spring push and abut against the valve element together, so that the valve element abuts against the stop part at a certain pressure, and the opening pressure of the valve element is controlled.

Description

technical field [0001] The invention relates to the technical field of water conservancy control, in particular to a water conservancy control valve with hydraulically controlled opening pressure. Background technique [0002] The hydraulic control valve with hydraulic control opening pressure is the valve controlled by hydraulic pressure. The hydraulic control valve consists of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to the purpose, function and place of use, it can be evolved into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc. [0003] A filter should be installed before the hydraulic control valve with hydraulic control opening pressure, and it should be convenient for sewage discharge. This type of valve should generally be installed horizontally in the pipeline. Hy...
