CARX composite exhaust valve is the most commonly used exhaust valve in our country, which is improved on the basis of float and float lever exhaust valve. Floating ball lever exhaust device for micro venting under pressure; Float device for a large amount of intake and exhaust air for the first time under water or other conditions. Can increase the size of the exhaust port, making the intake and exhaust speed has greatly improved.
CARX composite exhaust valve body is barrel-shaped, the valve trim includes stainless steel ball, stem and disc. The valve installed in the pump outlet or send water distribution pipeline, used to exclude the accumulation of air in the tube to improve the efficiency of the use of pipelines and pumps, when the tube once the negative pressure, the valve quickly inhaled outside air to prevent The pipeline is damaged by negative pressure.
When the tube began to inject water, the valve flap in the open position, a lot of exhaust, when the air row is exhausted, the valve filled with water, the float rises and drives the valve closed, stop the exhaust, when the tube of water normal delivery, such as There is a small amount of air gathered in the valve to a considerable extent, the valve water level drops, the float along with the decline, this time the air from the hole discharge. When the pump stops, the tube water flow empty tube or negative pressure within the tube, then plug quickly open, inhale the air, to ensure pipeline safety.
working principle:
The utility model mainly utilizes the buoyancy effect of water on a floating ball. When the water level of the exhaust valve rises, the buoyancy effect of the floating gas on the same as the floating gas is automatically floated until the sealing surface of the exhaust port is connected to a certain pressure Automatically shut down, when the valve to reduce the water level, the ball will drop with the water level down, then the pipeline will be injected into the exhaust through a large amount of air, the valve belongs to the automatic valve.
When gas is spilled in the system, the gas will climb up the pipe and eventually gather at the highest point of the system. The exhaust valve is usually installed at the highest point of the system. When gas enters the valve cavity of the exhaust valve and collects in the exhaust valve In the upper part, as the gas in the valve increases, the pressure rises. When the gas pressure is greater than the system pressure, the gas will lower the water level in the chamber. The float will descend together with the water level to open the exhaust port. After the gas is exhausted, the water level will rise. With the rise, turn off the exhaust. By the same token, when negative pressure is generated in the system, the water level in the valve chamber drops and the exhaust port opens. Since the ambient atmospheric pressure is larger than the system pressure at this time, the atmosphere will enter the system through the exhaust port to prevent negative pressure. If you tighten the valve cap on the exhaust valve body, exhaust valve to stop the exhaust, under normal circumstances, the bonnet should be open. Exhaust valve can also be used with the cut-off valve supporting the exhaust valve for easy maintenance.
