Main application for pressure relief valve

Technical water supply system.

After the combination of pressure relief valve after the fluid through the filter, and then through the water control valve to enter the water point. If the pipeline overpressure, pressure relief valve will be fully open and timely release pressure.

1, the combination type pressure reducing valve in the premise of ensuring the unit with water, to provide stable and reliable low pressure cooling water. Its decompression ratio is up to 12:1. Combination type pressure reducing valve on the back of the system can be applied to the recoil of the poor media, the security lock system can ensure that the system is severely damaged when the outlet pressure is still maintained low pressure.

2, the technical water supply system installed on the water filter, you can provide clean water for the unit to prevent impurities into the unit damage. After the filter is installed in the combination type pressure reducing valve, the user can choose a smaller pressure level filter, but too many impurities will affect the performance of the pressure relief valve to play.

3, the technical water supply system on the hydraulic control valve can be quickly opened and closed to achieve the purpose of cutting off the flow of media and eliminate water hammer pressure pipeline. Good performance of the hydraulic control valve in the open and close at the same time can be carried out back to the sewage, to ensure that the conditions are not stuck.

4, the technical water supply system on the pressure relief valve can accurately maintain the safety pressure of the pipeline, once the pipeline exceeds the set pressure, the pressure relief valve will fully open and timely release pressure. Good performance pressure relief valve in addition to the feedback system, but also with a forced open handle, in case of failure can be switched feedback system or direct manual discharge.

Combined  pressure relief valve

Combined type pressure reducing valve is designed for vacuum equipment supply system tailored for the complex condition, the outlet pressure feedback locking system, and the main valve body. The difference between the combined valve and the valve is normal:

1, feedback system of mutual standby for downtime;

2, counterflush system applicable to more poor quality;

3, the outlet pressure locking system can lock the outlet pressure limit;

4, the decompression value can reach 12:1 is the largest, the highest application head 320 meters (JINGGANGCHONG Hydropower Station)

5, the maximum flow rate of more than 5000m /h 800MW fand stand-alone applications, the largest (Xiangjiaba Hydropower Station)

Acting pressure relief valve

The most simple valve, direct acting valve, with a flat diaphragm or bellows. Because it is independent of the structure, so there is no need to install an external sensing line downstream. It is a three volume valve in the smallest and most economical use, designed for low flow. Direct acting valve is usually the accuracy of the downstream set point +/-10%.

Piston type pressure relief valve

The two types of valve sets a valve pilot valve and main valve - in one. Pilot valve design and direct acting valve similar. The discharge pressure from the pilot valve acting on the piston, the piston to open the main valve. If the main valve is large, can not directly open, this design will open the main valve entrance pressure. Therefore, this type of valve, compared with direct acting pressure reducing valve in the same pipe size, the capacity and accuracy (+/-5%) higher. The same with direct acting pressure reducing valve is the internal perception of the pressure relief valve, install the sensor without external line.

Film type pressure relief valve

In this type of valve, double diaphragm instead of the inner guide valve in the piston. This increases the area of the diaphragm to open the main valve, and in the same pipe size, the capacity of Binet guide valve piston greater. In addition, the diaphragm is more sensitive to pressure, accuracy up to +/-1%. Higher accuracy is due to the positioning of the downstream sensing line (valve external), their location less volatile gas or liquid. The valve is very flexible and can be used by different types of valves (such as temperature, air pressure valve, valve loading valve, solenoid valve or several valves at the same time supporting the application).
