First, the structural characteristics and usefulness of 500X pressure relief valve
 

由主阀、泄压/持压导阀针阀、球阀、微形过滤器和压力表组成水力控制接管系统。 The 500X pressure relief valve consists of a main valve, a pressure relief / hold pressure pilot valve, a ball valve, a micro-filter and a pressure gauge. Utilizing hydraulic automatic operation, it can be used as both pressure relief valve and holding pressure valve.
When used as a pressure relief valve, the pressure of the water supply line can be maintained below the set safe value; as a holding valve, it can maintain the water pressure upstream of the main valve above the set value and maintain the water supply pressure upstream of the main valve. This product uses hydraulic self-control,
No other devices and energy are needed, easy maintenance and multiple valves. 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。 800X differential pressure bypass 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 500X pressure relief valve
 

1. As a pressure relief valve: When the pressure relief / hold pressure pilot valve is adjusted to a pressure relief state, water flows to the outlet through the needle valve, main valve control room, ball valve A, pressure relief / hold pressure pilot valve, and ball valve B. At this time, The main valve is open.
When the inlet pressure exceeds the safety value set by the pressure relief / hold pressure pilot valve, the pressure relief pilot valve will automatically open, and some water will be discharged through the ball valve C to release the pressure in the pipeline. When the pressure returns to a safe value, the pressure relief valve closes automatically.
When used as a pressure relief valve, each ball valve is always open.
2. As a holding pressure valve: When the pressure relief / holding pilot valve is adjusted to a holding state, as long as the inlet water pressure of the main valve is lower than the set value of the pilot valve, the pilot valve is closed. The main control room is boosted and the main valve is closed. When the water supply pressure upstream of the main valve
When the pressure set by the pilot valve is exceeded, the pressure-holding pilot valve can be opened. The water in the control room is discharged to the outlet through the ball valve. When used as a holding valve, the ball valve C is normally closed
Or replace it with a wire plug.
