是国内著名〖 200X减压稳压阀 〗制造商,也是国内大型【 水力控制阀 】生产商之一,公司自成立以来始终围绕客户的需求并持续创新,为广大的代理商和企业客户提供〖200X减压稳压阀 〗解决方案,质量可靠,价格实惠,故畅销全国各地,欢迎新老客户来电,来函,我们将为您提供最优质的服务。 Hushan Valve Manufacturing (Shanghai) Co., Ltd. is a well-known manufacturer of 200X pressure reducing regulators in China and one of the large domestic manufacturers of [ hydraulic control valves ]. The vast number of agents and corporate customers provide the "200X pressure reducing and regulating valve" solution, which is reliable in quality and affordable, so it sells all over the country. Welcome new and old customers to call and email us, we will provide you with the best service.

First, the structural characteristics and usefulness of 200X pressure reducing valve
 

由主阀、导阀、针阀、球阀、微型过滤器和压力表组成水力控制接管系统。 The 200X pressure reducing and stabilizing valve is composed of a main valve, a pilot valve, a needle valve, a ball valve, a micro filter and a pressure gauge. In use, when the outlet pressure is adjusted, it can automatically maintain a stable outlet pressure.
This product uses pilot valve self-control, no other devices and energy are needed, easy maintenance, high accuracy of pressure control, little effect of inlet pressure and flow, reliable pressure reduction and voltage stabilization. 广泛用于高层建筑、生活区等供水管网系统及城市供水工程。 400X flow control valve is widely used in high-rise buildings, living areas and other water supply pipe network systems and urban water supply projects.
 

Working principle of 200X pressure reducing regulator:
 

When the valve feeds water from the inlet, water flows through the needle valve into the main valve control room, and the outlet pressure acts on the pilot valve through the conduit. When the outlet pressure is higher than the pilot valve spring setting, the pilot valve is closed. Control room stops draining
At this time, the main valve controls the pressure in the room to rise and closes the main valve, and the outlet pressure no longer increases. When the valve outlet pressure drops to the pressure set by the pilot valve spring, the pilot valve opens and the control room drains downstream. Due to the pilot valve system
The amount of water is greater than the amount of water entering the needle valve, and the pressure in the control room of the main valve drops. The inlet pressure opens the main valve. In a stable state, the inlet and outlet of the control room are the same, the opening degree of the main valve is unchanged, and the outlet pressure is stable.
Adjust the pilot valve spring to set the outlet pressure.
