 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:What is valve packing used for?
Mainly from the role of sealing, to prevent leakage of the valve conveying medium, stuffing commonly used PTFE, graphite, asbestos packing three.
Q:What is the KVS in the valve parameter?
The Kvs of the valve reflects the passing capacity of the valve
Q:How to use current to control valve opening and closing?
You don't know if the precision requirement of high precision can be used for high requirements of valve control valve (4-20mA) control but need converter needs the temperature signal into your current signal control valve (4-20mA) valve door factory will not have this thing you can ask to do control system manufacturers (in tell you part of the valve switch and adjust the price of at least 1000 points (OH) to not give me angry) is something you can ask me the valve factory
Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
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 to open the gas valve?
Are you talking about using air? Or your valve is a pneumatic emergency shut-off valve
Q:Which industries need valves?
Valve application industryValve users in a wide range of industries, can be divided into petroleum, petrochemical, chemical, metallurgy, electricity, water conservancy, urban construction, machinery, coal, food and other. Among them, the machinery and chemical industry users are most concerned about the valve market, and their requirements for the valve is also higher. The largest users of valves are the petrochemical industry, the power sector, the metallurgical sector, the chemical industry and the urban construction sector.Valve application typeIn the application of the types of valves, machinery, metallurgy, petrochemical, chemical, urban construction and other industries, the application of the valve classification of the most. Especially in the machinery industry, all kinds of valves are basically applied. In addition to the mechanical industry, the safety valve is mainly used in chemical industry; butterfly valve is mainly used in petrochemical and metallurgy; diaphragm valve is mainly used in metallurgy, electric power and chemical industry; check valve is mainly used in metallurgy, chemical and petrochemical; valve mainly used in petroleum and chemical industry; the cut-off valve is mainly used in metallurgy, petrochemical, chemical and power sewage; valve is mainly used in petrochemical and chemical industry; the ball valve is mainly used in petroleum, chemical and metallurgy; valve is mainly used in chemical industry, electricity and construction; the valve is mainly used in chemical, metallurgical, power and food; used in petrochemical and metallurgy main plunger valve; plug valves are mainly used in chemical and metallurgical valve; mainly used in petrochemical, chemical and metallurgy; steam traps are mainly used in chemical and petrochemical.
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:The valve of the solar energy was broken by me. Do you know what is called?
An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.
Q:What are the valve types H, F, and Y? What are the meanings of these 3 letters?
Please refer to "JB/T308-2004 valve model preparation method"Sealing surface material codeH Cr13 stainless steelF fluoroplasticY cemented carbide
