 Air Evacuation Valve  Specifications

1. good structure
2. pressure and impact
3. stability performance

Air Evacuation Valve Status: when the pressure is lower than the Standard Atmospheric Pressure in the ash silo, it generates vacuum in the silo. Then the film works and adjusts the air pressure back into the safety range.   

2.Product Introduction 

Air Evacuation Valve (So-called Ash Silo Relief Valve or Ash Silo Vacuum Relief Valve): is mainly used on the top of the Steel Silo or Ash Silo to release the extra pressure so that it will stay at a safe range all the time. Vacuum Relief Valve is made up of lid, spring ring, movable ring, film, spring of the retainer ring, retainer  ring, valve lid, Valve base. 

 Air Evacuation Valve is considered as a must-have facility for the ash silo.The pressure may change when the air stream inflows the ash silo or outflows, or the temperature rises or reduces. Release Valve protects the silo from safety hazard

3.Working Principle 

 1.Static status: Once you set up a pressure range. Normally,  pressuer could be maintained at a stable level in the ash silo.The valve lid keeps static, and the whole valve is completely sealed.

2.Pressure-Release Status: when the pressure rises upon the setted range, the valve lid would be opened automatically to release the extra airstream.As the pressure goes down to the standard level, the valve lid would be closed automatically.

 3.Vacuum-Released Status: when the pressure is lower than the Standard Atmospheric Pressure in the ash silo, it generates vacuum in the silo.Then the film works and adjusts the air pressure back into the safety range.So that, Relief Valve protects the silo from safety hazard.

Q:What are the general types of valves?
Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Function and use(1) cut off categories: such as gate valve, globe valve, plug valve, ball valve, butterfly valve, needle valve, diaphragm valve and so on. Cut off valve, also known as closed-circuit valve, stop valve, whose role is to connect or cut off the pipeline medium.Check valves, also known as check valves or non-return valves, check valves belong to an automatic valve, its role is to prevent the pipeline medium backflow, to prevent the pump and drive motor reversal, as well as the leakage of container media. Pump water off the bottom valve check valve also belongs to class.The function of the relief valve is to prevent the medium pressure in the pipeline or device from exceeding the required value so as to achieve the purpose of safety protection.Control valve, throttle valve and pressure reducing valve, its role is to regulate the media pressure, flow and other parameters.(2) vacuum type: such as vacuum ball valve, vacuum flapper valve, vacuum air charging valve, pneumatic vacuum valve, etc.. Its function is to change the direction of the air flow in the vacuum system, adjust the air flow rate, cut off or connect the vacuum system of the pipeline, and the component is called the vacuum valve.(3) special uses such as pigging valves, vent valves, drain valves, exhaust valves, filters, etc.. The exhaust valve is an essential auxiliary component in the pipeline system. It is widely used in boilers, air conditioners, petroleum, natural gas, water supply and drainage pipelines. Often installed in the commanding heights or elbows, etc., to exclude excess gas pipeline, pipe road to improve the use of efficiency and reduce energy consumption.
Q:Heating pipes, in addition to the living room,
It is loaded against the supply and return water pipe is not underground do in next time if it is to see if there is any water on the side of the baffle remember from the baffle recently if it is normal that is motivated next must put off the baffle
