SCAR series sewage combined exhaust valve
Overview:
The principle of sewage combined exhaust valve is the same as that of clear water combined exhaust valve, except that the structure is slightly modified, that is, the valve body is lengthened, and the lever mechanism is slightly modified, so that the dirt only accumulates in the lower part of the valve body, and does not affect the exhaust gas. Leaking water.
Main specifications:
Pressure rating: PN10
Nominal diameter: DN50-200mm
ARSX/ARSH series micro-exhaust valve ARSX/ARSH series under normal circumstances, the water contains about 2VOL% of dissolved air. During the water delivery process, these air are continuously released from the water and gather at the high point of the pipeline to form The air bag (AIR POCKET) makes water delivery difficult, and the system's water delivery capacity can be reduced by about 5-15%. The main function of this micro-exhaust valve is to eliminate the 2VOL% dissolved air, and it is suitable for installation in high-rise buildings, factory piping, small pumping stations to protect or improve the system's water delivery efficiency and save energy.
SIMPLE LEVER TYPE micro-exhaust valve is an elliptical valve body. All internal parts including float ball, lever, lever frame and valve seat are 304S.S stainless steel. The internal exhaust standard is 1 /16", suitable for working pressures up to PN25. Main specifications:
Nominal diameter: DN15-DN25
Nominal pressure: PN10 PN16 PN25
CARX series compound exhaust valve
Construction and use:
The valve is a barrel-shaped valve body, which mainly contains a group of stainless steel balls (STAINLESS STEEL BALL), rods (FLOAT ARM) and plugs (POPPET). The valve is installed at the pump outlet or in the water distribution pipeline to remove a large amount of air collected in the pipe, or a small amount of air collected at a higher point of the pipeline is discharged to the atmosphere, so as to improve the efficiency of the pipeline and the pump, and When a negative pressure is generated in the pipe, the valve quickly inhales the outside air to protect the pipeline from damage caused by the negative pressure.
Operating principle:
When the water injection starts in the tube, the plug stays in the open position and performs a large amount of exhaust. When the air is exhausted, water accumulates in the valve, the float is floated, the plug is driven to the closed position, and a large amount of exhaust is stopped. During normal transportation, if a small amount of air accumulates in the valve to a considerable extent, the water level in the valve drops, and the float ball descends. At this time, the air is discharged from the small hole. When the pump stops, the water in the tube is empty or a negative pressure is generated in the tube. At this time, the plug is quickly opened and air is sucked in to ensure that the pipeline is complete.

The exhaust valve is an indispensable auxiliary component in the pipeline system and is widely used in boilers, air conditioners, oil and gas, and water supply and drainage pipes. It is often installed at the commanding heights or elbows to eliminate excess gas in the pipeline, improve the efficiency of the pipeline and reduce energy consumption.
