Description
400X hydraulic flow regulator control valve
400X hydraulic flow regulator control valve Principle
hydraulic flow regulator control valve When the valve is supplied with water from the inlet end, the water flows through the needle valve into the main valve control room, and flows out of the main valve control room through the pilot valve and ball valve to the outlet. At this time, the main valve is in a fully open or floating state. Setting the flow regulating valve on the upper part of the main valve can set a certain opening degree of the main valve. Adjusting the opening of the needle valve and adjusting the spring pressure of the pilot valve can keep the opening of the main valve at the set opening, and the pilot valve will automatically adjust when the pressure changes to keep the flow constant.
Characteristic
hydraulic flow regulator control valve easy to install and easy to use. The control part has no complicated electric sensing mechanism. It is not easy to break down, set simple, and automatically complete the adjustment function after setting. No manual operation or other power source is required.
hydraulic flow regulator control valve is installed in the situation where the water pipe line needs to control the flow, so as to keep the predetermined flow rate unchanged, the excessive flow is limited to a predetermined value, and the upstream high voltage is reduced to the lower pressure. Even if pressure changes upstream of the main valve, it will not affect downstream flow.
