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:How do you understand the valve Z41X-16?
- This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron
- Q:How to carry out the valve strength test and air tightness test?
- All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed
- Q:What does the valve QF mean?
- Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
- Q:What's the sewage treatment valve with?
- Sewage treatment system valve requirements are not high, the use of butterfly valve is one of the most cost-effective.
- Q:What does the ZH41 valve ZH41 mean, and what other specifications?
- Is the model wrong? The correct one should be Z41HGate valve, hand flange connection name, rod type single gate, sealing surface is alloy steel
- Q:What does the PN on the valve mean?
- 1, mark "ON25" and "PN16" respectively what does that mean? 2, the valve above has an outer six corners, so PN16 refers to the nominal pressure of 16 kg valve. Valves on the fittings are standard parts, special
- Q:What does "DN15" mean? What does "PN 16" mean?
- DN15 refers to the diameter of the valve, that is to connect the caliber of the pipe.PN16 means pressure, that is, 16 kilograms (1.6MPa).
- Q:What do you mean by the 16 bit coding of the valve type?
- What kind of coding do you mean? Valve type? Stress? Do you have these?Profit ZF43Y-250C-DN50.. Do you mean this one? ZF43Y valve type. Flat gate valve250C. Refers to the 250 pressure, C is carbon steel, DN50 refers to the caliber of the valve specificationsI hope you mean this one
- Q:How to open the gas valve with drawings
- It's different from place to place. Some are pulled out half, and some are pulled out. 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
- Q:What's the difference between a valve and a valve?
- The correct unit should be called "group". A set of threaded valves include valves, live connections, and short tubes. A set of flanged valves consist of a pair of flanges (including bolts, gaskets, rubber pads), and short tubes".
