I. Overview of GWP type high flow combined exhaust valve

GWP high-flow combined exhaust valve: It is used for the highest point or elbow on the pipeline or where there is air tightness, to exclude the gas in the pipeline to clear the pipeline and achieve normal work. If this valve is not installed, the air resistance of the pipeline will occur at any time, which will cause the water capacity of the pipeline to fail to meet the design requirements. Secondly, a blackout of the pipeline when the pipeline is running and a negative pressure in the pipeline will cause the pipeline to vibrate or rupture. 可防止浮球在高速气流中被吹起而堵塞排气口,造成排气阀失效。 GP4X power type high-speed exhaust valve can prevent the floating ball from being blown up in high-speed air flow to block the exhaust port and cause the exhaust valve to fail.

Working principle

When water enters the pipeline, the plug stops at the lower part of the positioning frame for a large amount of exhaust. When the air is exhausted, the water enters the valve to float the ball, and the plug is closed to stop the exhaust. During normal operation of the pipeline, a small amount of gas will naturally be generated, and these gases will collect to the upper part of the tube. To a considerable extent, the water level in the valve will drop, and the floating ball will be discharged along the water from the small hole. Negative pressure occurs at any time, and the float drops down the water. Opening the small holes drives the large holes for a large amount of air intake to ensure the safety of the pipeline.

Fourth, installation requirements

1. Before installation, please check and remove the sundries in the main body.
2. Install a gate valve in front of the valve for next installation and maintenance. If the valve is installed in the shadow well, there should be enough space to accommodate technicians' adjustment and maintenance work.
3. If the high-flow combined exhaust valve is installed outdoors, please pay attention to the thermal insulation of the valve to prevent the water in the valve from freezing or cracking the valve.
4. If the pipeline where the exhaust valve is located sends water frequently, it is recommended to install a buffer valve in front of the exhaust valve.
