 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

Q:How to check the quality of the valve?
First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level.Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem.Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.Valve (Famen) 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.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
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:What are the types of valves?
1.1 classification by purpose and functionx09 (1) cut-off valve is mainly used to cut off or switch through the media flow, including gate valve, globe valve, diaphragm valve, ball valve, plug valve, butterfly valve, plunger valve, ball plug valve, needle type instrument valve, etc.x09 (2) control valve is mainly used to regulate the flow of medium, pressure, etc., including regulating valve, throttle valve, pressure reducing valve and so onx09 (3) check valves are used to prevent backflow of media. Check valves with various structures are includedx09 (4) diverter valves are used for separation, distribution, or mixing of media, including distribution valves and traps for various structuresx09 (5) safety valves are used to protect the medium against overpressure. Various types of safety valves are included1.2 classify by main parameters
Q:Dalian hi Max Valve Co., Ltd.
Oh, the above two estimates are bullshit I know domestic listing only Guangdong pearl valveI do the valve, looking at the landlord's points, I do the valve industry, let me talk about itDalian high valve plant mainly produces valve forged steel production is especially good at 800 pounds of power station gate valve globe valve check valve many Wenzhou doing this type of valve is to take his product imitation
Q:Is there a one-piece, two linkage valve?
In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.
Q:What's the valve as a unit?
Business now there are many valve manufacturers, with the rapid expansion of SMEs, SMEs are more ~!
Q:How does the valve rust die?
Go to the hardware store to buy derusting lubricant, W40 is fine.
Q:What do you mean by the 16 bit coding of the valve type?
Not regular encoding. Regular encoding is usually 11 bit and sometimes 13-14 bit
Q:Hydrant valve leaks, how do you close other valves? Specific steps?
Hello my name is Baidu know the long days of high water leakIn the vicinity of a common fire hydrant, there is a valve, which is convenient for fire hydrant maintenance, because fire hydrant repairs need to close the water source. Look around, it should be easy to find the valve. Switch valve is very simple, and the direction of the twist screw is the same, clockwise turn off, counterclockwise is open. Closed valve, fire hydrant will not leak, you can feel relieved to repair. I guess your fire hydrant is sealed rubber pad, aging causes leakage, it is a common disease of fire hydrants.
Q:What is the difference between the adjustable range of valve 50:1 and 100:1?
Said is the valve bar, adjustable valve range refers to the adjustable ratio, that is, the maximum flow control valve can be controlled with the minimum flow ratio.The regulating ratio of the regulating valve is the ratio of the maximum flow and the minimum flow that the control valve can control.
