Water Pressure Hydraulic Control Valve for Water

Product Description

Hydraulic control valve is the water pressure control valve, hydraulic control valve by a main valve and its attached catheter, guide valve, needle valve, ball valve and pressure gauge and other components. According to the use purpose, function and place of different, can be evolved into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, relief valve, hydraulic electric control valve, pump control valve, etc.. The filter should be installed before the hydraulic control valve, and it should be convenient for sewage discharge. This type of valve should be installed horizontally in the pipeline.

Principle & Structure

Hydraulic control valve is a valve which uses the medium pressure of the pipeline as the power to start, close and regulate. It consists of a main valve and attached to the catheter and needle valve, ball valve and pressure gauge, etc. according to the purpose and function of the different places, can be turned into a remote control float valve, relief valve, relief valve closed, flow controller, pressure relief valves, hydraulic control valves, emergency shut down valve. Change the pilot valve with the medium level and pressure action, as many types of pilot valve can be used alone or in combination, you can obtain the main valve separately and combined adjustment function of water level and water pressure and flow etc.. But the main valve similar to the cut-off valve, the valve fully open, the pressure loss is much higher than the other valve, and opening all the more with the loss coefficient close to the fully closed state, the more dramatic increase in valve diameter the greater the more significant.
Valves with the above characteristics, in the approaching valve action acceleration, prone to water hammer impact, close to the full closed, the valve action as slow as possible, so you can set throttle device on the valve disc. In addition, the pilot valve throttling and action part should try to avoid setting small caliber orifice, so as not to plug. Filter network is necessary, periodic maintenance and bypass piping are necessary. Control diaphragm type and piston type two hydraulic valve, the working principle is the same, the upstream and downstream pressure difference as the driving force, a pilot valve control, the diaphragm (piston) hydraulic differential operation, fully automatic adjustment by the water, so that the main valve is fully open or fully closed or in regulation.
When entering the diaphragm (piston) pressure control room above the water is discharged to the atmosphere or the downstream effect under the low pressure area valve and diaphragm low value is greater than the pressure above the pressure value, which will be the main valve to the full open position: when entering the diaphragm (piston) control room pressure at the entrance and exit pressure value since the middle of the main valve, the valve is in regulation, combined with control effect of needle valve and pilot valve the regulation depends on the location of the catheter system.
The pilot valve can open or close its own small valve port through the change of the downstream pressure, thereby changing the pressure value of the control chamber above the diaphragm (piston), and controlling the regulating position of the main valve clack. It can be used in domestic water supply, fire protection system and industrial water supply system.
