CARX composite exhaust valve is cylindrical, valve parts, including stainless steel floating ball lever and valve. This valve is installed at the outlet of the pump or water distribution pipelines, to exclude accumulation in the air in the tube, to improve the efficiency of the use of pipeline and pump, when the tube once produced steel pressure, the valve quickly inhale outside air, to prevent the pipeline from being damaged due to negative pressure. When the water starts the tube when the valve is in the open position, a large number of exhaust valve, when water filled the air drained when the floating ball rises and drives the valve closed, exhaust pipe when the water stop, normal transport, such as a small amount of air accumulation to a considerable extent on the valve, the water level dropped valve at this time, the air discharged by the hole. When the water pump stops, the water in the pipe is empty or a negative pressure is generated in the pipe. At this time, the plug head is opened quickly, and the air is sucked in to ensure the safety of the pipeline.
Water control valve is the pipe medium pressure as the driving force for opening and closing, regulating valve. It consists of a main valve and attached to the catheter and needle valve, ball valve and pressure gauge, etc. according to the purpose and function of the different places, can be turned into a remote control float valve, relief valve, relief valve closed, flow controller, pressure relief valves, hydraulic control valves, emergency shut down valve.
Hydraulic control valve action:
1, It can be used in domestic water supply, fire fighting system and industrial water supply system.
2, hydraulic control valve to use the pilot valve to control the opening and closing of the valve, saving energy.
3, can replace other valves, large electric device.
4, hydraulic control valve products are widely used in high-rise buildings, living areas and other water supply network systems and urban water supply projects.
