Product overview:
400X flow control valve, is a high-precision pilot way to control the flow of multi-function valve. It is applicable to pipelines where the flow and pressure of the distribution pipe need to be controlled. The predetermined flow should be kept unchanged, the excessive flow should be limited to a predetermined value, and the upstream high pressure should be lowered appropriately. Even if the upstream pressure of the main valve changes, the downstream flow of the main valve will not be affected. 400X flow control valve to change the conventional throttle valve using orifice plate or pure mechanical zang small watershed area principle, the use of related guide valve, reduce the energy loss in the throttling process. In case of emergency 400X flow control valve can cut off the flow to avoid loss. High control sensitivity, safe and reliable, easy debugging, long service life.
Structural features and USES:
The 400X flow control valve consists of the main valve, flow control valve, needle valve, guide valve, ball valve, microform filter and pressure gauge. Hydraulic automatic operation is used to control and adjust the opening of the main valve so that the flow through the main valve remains unchanged. The 400X flow control valve is controlled by hydraulic power by itself without other devices and energy. It is easy to maintain and stable flow control. This series 400x flow control valve products are widely used in high-rise buildings, living areas and other water supply network systems and urban water supply projects.
Working principle:
When the valve feeds water from the inlet end, water flows through the needle valve into the main valve control room and out of the main valve control room to the outlet through the guide valve and ball valve. At this time, the main valve is in a fully open or floating state. Adjust the flow control valve of the upper part of the main valve, the main valve can be set a certain degree of opening. By adjusting the needle valve opening and the spring pressure of the guide valve, the opening of the main valve can be kept at the set opening, and the guide valve can be automatically adjusted when the pressure changes to keep the flow constant.
Scope of use: the product can be used in production, living and fire water supply and drainage system.
The product conforms to the standard: GJ/T 219 JB/T 10674.
