 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

1. Customized is allowed.
2. Installing in welding or bolts.
3. Factory price.
4. Stock any time.
5. Positive rating:100%.
6. Neccessary device in storage silo.

Q:How do you see the valve number?
The meaning of valve number:Valve type Z, J, L, Q, D, G, X, H, A, Y and S respectively: gate valve, globe valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, relief valve, drain valve.The connecting codes for valves are 1, 2, 4, 6, 7, respectively: internal thread, 2, outer thread, 4, flange, 6, welding, 7, pair.Valve transmission mode code 9, 6, 3, respectively, said: 9, electric, 6, pneumatic, 3, turbo worm.Body material Z, K, code Q, T, C, P, R and V respectively: grey cast iron, malleable cast iron, ductile iron, copper and alloy, carbon steel, stainless steel, chrome nickel chromium nickel molybdenum stainless steel, chromium molybdenum vanadium steel.Seat sealing or lining R, T, X code, S, N, F, H, Y, J, M, W respectively: austenitic stainless steel, copper alloy, plastic, rubber, nylon plastics, fluorine plastic, Cr stainless steel, hard alloy, rubber lining, Monel alloy, valve body material.
Q:Pressure gauges, safety valves and other safety accessories and the cylinder can be installed between other valve components,
The lower part of the pressure gauge installed water pipe, there are water, avoid high temperature, medium pressure gauge contact directly cause damage, so regular cleaning, in order to avoid congestion, three way plug function is used for flushing, please see "how to operate them.".
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:How can I install the water pipe valve?
Look, the valve you bought looks like PVC hot melt.. If the old valve and the elbow must be rejected with a hacksaw, hot melt and buy a new elbow and PVC section pipe for hot melt machine welding. From the picture didn't see traces of the thread,
Q:Is there any problem with connecting the geothermal valves with other geothermal pipes?
Can be universal,Material is the same, the fuse will not cause shrinkage when you can use
Q:What do the D373W and D373H of the valve mean?
Butterfly valve, worm drive for the folder inclined plate, H alloy steel lining, W for the valve body directly processing sealing surface.
Q:How much is the 150LB of the valve?
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.
Q:What are the production equipment in valve shop?
Machining equipment: CNC, universal car, milling machine, drilling machine (rocker arm drill), wire cutting, grinding machineTest equipment: valve test press according to the production of valve pressure, specifications, types of procurement.
Q:How many triangular valves and other valves are used in kitchen and toilet decoration?
The best way is to ask the master to calculate, you go to purchase!!
Q:What is the difference between low pressure valves and medium pressure valves and high pressure valves?
In fact, this is only the valve industry sector argument, not necessarily to distinguish between very clear.As long as the customer pressure requirements, we give him the drawings on it.Valve flange thickness and valve thickness are not standardized, according to pressure requirements.The flange thickness of 6.4Mpa and 10Mpa is completely different from that of valve body.For example: general gate valve, the most basic pressure 1.6MPa, according to GB/T139272008 and JB/T90921999 standard castingGenerally selected 1.6MPa, when the highest pressure pressure is 1.6X1.5=2.4MPa, if you exceed this pipeline pressure is not, there are now many manufacturers in order to save costs, the valve wall is thin, a conventional valve pressure 1.6MPa is a bit difficult.My own boundaryVacuum negative pressure 0.05Mpa-0.5Mpa0.6Mpa-1.6Mpa belongs to normal pressure (low pressure)2.5Mpa-4.0Mpa belongs to medium pressure6.4Mpa-10Mpa-16Mpa-25Mpa-32Mpa-42Mpa belongs to high pressure50Mpa-80Mpa belongs to supercritical high pressure valve
