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.

Customers’ Guidance:
Please leave the following info in inquiry
1. What’s the raw material ( carbon steel or stainless steel )
2. What’s the entrance diameter( 508 mm /273 mm or customized)
Because with these factors, we are able to give you a fast answer.
- Q: Where is the Shanghai valve? What brand is good?
- Shanghai has four well-known valves: Shanghai high valve group Co. Ltd., Shanghai Valve Co., Ltd. Shanghai Jinggong valve factory, Shanghai Valve Factory Co., Ltd.
- Q: What are the other valves used for the control of dual-use items?
- That is to say, your valve needs to be used as dual-use items and technology import and export licenses. Shanghai import and export can find me. We have electronic keys for dual-use items
- Q: What courses in the University involve valves?
- Fluid mechanics, "material mechanics", "mechanical design" and other courses on the design of the valve are helpful.
- Q: 1/2, what does 1/4 valve mean? I don't understand. What does this number mean? Have a valve to introduce me, do not copy a pile of online introduction, I want to concise
- I have to answer a simple 1/2 1/4 is American Standard valve diameter to the national standard to calculate it is 1/2=DN15 1/4=DN8Also on the valve size of the meaning of the Wenzhou essence valve factory for you to answer
- Q: 1) the valve plate, valve gate valve, the difference (my personal understanding is that if it is on the ball, called the valve, if the valve is called the gate, is actually a meaning in different valve called, please help me understand it right?)2) valve clack. What's the spool?3) the valve seat is welded inside the valve, or is it directly installed inside without welding?4) when opening the valve, if the valve seat is not welded, then, under the pressure of the medium, why not open the seat?.5) excuse me, pressure self sealing (my personal understanding is that when the valve is closed, the valve plate and valve seat depend on the pressure of the media, and they fit together to seal the effect
- 1. can be understood that way2, check valves, stop valves, and throttle valves are called valves3., welding, thread, and there is a cylindrical indentation, as well as plastic deformation press in4, without opening, there is a sphere or other block, open the moment, the pressure will come down, the media through the channel, attack or blocked by the ball, huh, huh5, the pressure self tight refers to the middle flange, where the greater the pressure, the more reliable sealing, within a certain rangeWhen the cut-off valve diameter is less than 150, the medium is low, the inlet is higher and the outlet diameter is greater than 200Some of them are self locking by thread, and some of the globe valves are equipped with locking devices
- Q: How do I open the gas valve?
- Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all. 1, according to the routine, now the handle position shows that the valve is open. 2, if the handle rotated 90 degrees, the gas pipeline gas has no change, should be the stem slipped, can not drive the valve ball rotation. Try rotating several times. If it still doesn't work, ask a professional to check it out.
- Q: What valve is the YQZ45X-16Q?
- Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.
- 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 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: How are the types of valves classified?
- Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion.
