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: Proportional valve why than other small pipeline valves
- 3.8 valveGraphical representation of numbers, names, symbols3.8.1 angle valve at room temperature3.8.2 cold angle valve for low temperature use3.8.3 stop valve at room temperature3.8.4 ball valve often 9 temperature3.8.5 valve at room temperature3.8.6 butterfly valve at room temperature3.8.7 check valve flow from blank triangle to non empty triangle3.8.8 pressure reducing valve, small triangle for high voltage end3.8.9 throttling valve is needle valve3.8.10 three-way valve for normal temperature use3.8.11 four way valve used at normal temperature3.8.12 safety valve spring type safety valve3.8.13 trap actual drawing, you do not have to draw arrows3.8.14 inflator, cold box, little gas huff and puff, safe useValve for normal temperature of regeneration valve of 3.8.15 reverse stop valve3.8.16 reverse loading cold angle valve
- Q: Where is the filling portion of the valve?
- The middle of the screw down valve handwheel saw packing gland generally about two screws fixed or fixed on the pressure cap down is the appearance of the packing is not seen inside if leakage occurs usually filler filler fastening screws, general pressure valves are graphite filler
- 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 valve is the DN 25?
- DN25 is just a caliber, a variety of valves, depending on your actual needs to buy Valves, water or gas, or other special functions, are the basis for the purchase of the valve must be provided
- Q: How about leaking water pipe valve?
- It depends on where the place is leaking.1, if it is household valveA, the valve and pipe connections at the leakage, in the connection, do not rub tape (the best counter clockwise direction, so that when the valve is connected, the more twisted the more tight) ;B, if the valve itself in the leak, there are ways, it is necessary to open the valve, in which to add sealed or O ring, but it is recommended to replace a more convenient.2, if it is industrial valvesA, industrial valves leaking, if not the valve itself in the leak, then in the valve and pipe connections to join the sealing ring,B, if the valve itself is leaking, it is best to return to the manufacturer for maintenance, if not convenient, then only the manufacturers to come here for maintenance.
- Q: Can other valves be used instead of 10?
- An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.
- 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
- The first question is basically the same, and you can understand that for the secondThe 3,4 problem, there are several seat connections, such as thread connection (threaded, the valve seat is connected with the valve), modular connection (such as adding the cage to a fixed seat, the crushed) as one of the body and there is (some welding). The valve seat must be fixed.The fifth question, you are right!
- Q: What does the "Z45T-16" valve mean?
- Z - gate valve4 - flange connection5 - Dark pole, stem non lifting (gate valve structure)T - copper alloy, valve sealing face code16 - pressure code, 1.6MPaMaterial code for grey cast iron valves of nominal pressure less than or equal to PN16 shall be omitted in model preparation.May refer to JB/T 308 valve model compilation method
- Q: What should be checked before using the valve?
- The valve must be tested before installationI. examination of documentsThe valve must check the quality documents before installation, the valve manufacturer should be nameplate, nameplate and the body should be the name of the manufacturer, valve type, nominal pressure, nominal diameter and logo, must comply with the "universal valve logo" GB 12220.Two, appearance inspection
- Q: What are the ten major brands of China's valves?
