 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.

4.Features

1. Customized is allowed.
2. Installing in welding or bolts.
3. Factory price.
4. Stock any time.
5. Positive rating:100%.
6. Neccessary device in storage silo.

Q:What kind of valve is it? How do you see the status of the switch?
Globe valve, not ball valveClockwise (Bell) needle to reduce the flow to the end of the shutdown, the counter clockwise to open. You can turn the multi circle plate will also lift up and down. The spindle, to the top is open, down to the edge off.The ball valve has a strip handle, the line is connected, and the cross is turned off
Q:Where is the Shanghai valve? What brand is good?
A lot of Shanghai brand brand of Shanghai KaiWeiXi, Department of finance the Kemei high Lidun Shanghai Karon these are good
Q:The difference between fire general valve and fire fighting special valve
Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.
Q:Can the gas valves be switched off regularly?
The small valve called skin stopcocks, his design is often switch, but for the sake of safety, natural gas company also installed a lock valve in front, once the leak immediately close the valve, the valve once closed to find a Gas Co came to open, so it is not necessary the case don't go off.What we usually need to pay attention to is..:1, every time you finish cooking, you must close the pipe plug valve (the valve you said).2, regular inspection of the skin tube leakage (3 months 1 can be this).3, the leather pipe and the leather pipe plug valve connected to the place has a ferrule, inspection found loose, must be tightened with a screwdriver, in case of leakage.4, the use of gas should pay attention to indoor ventilation, winter must open lampblack machine, in case of poisoning.Don't worry as long as you do the above.
Q:How big valves are used in a DN159 pipe?
Nominal diameter DN150 corresponds to the outer diameter of De159To say DN159 is wrong, because DN is the nominal diameter (diameter in the middle of the tube wall)De159 refers to the outside diameter (outside the diameter of the wall)DN39 should be DN32. Nominal diameter 32, outer diameter 39.
Q:What is called protective valve, and other valves what is the difference?
Protection valve should be in the air defense valve, can be copper gate valve. (according to the specific use of civil air defense requirements, design institute does not count).2, while the protection valve should be a locking device with the valve, not the general valve can be replaced.
Q:Which industries need valves?
Valve as a general component, widely used in various industries, but there are three main purpose of application in various industries:1, routine inspection needs;2, new projects supporting;3, emergency reserves.Valve market trendsDue to changes in user demand, the market trend of valve products will also change accordingly. In the future, the main trends are as follows:1 with the transfer of oil development to the mainland oil fields and offshore oil fields, and the power industry under the 300 thousand kilowatts of thermal power to more than 300 thousand kilowatts of thermal power and hydropower and nuclear power development, and valves should be changed based on device applications and the corresponding changes in its performance and parameters;2 urban systems generally use a large number of low-pressure valve, and to the development of environmentally friendly and energy-saving, low iron gate that is used in the past gradually shifted the environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and the center line butterfly valve seal transition, oil and gas pipeline projects to develop in the direction, which in turn requires a large number of flat gate valve and ball valve the;
Q:What valve is the FCV?
It's FCU, Fan, Coil, Unit, fan coil valves
Q:Chinese valve and a valve which is better?
Look what valve you use, ah, these two can be ah!
Q:Valve difference
