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.

Customers’ Guidance:
Please leave the following info in inquiry
1. What’s the raw material ( carbon steel or stainless steel )
2. What’s the entrance diameter( 508 mm /273 mm or customized)
Because with these factors, we are able to give you a fast answer.
- Q:What does 3/4''mean in the name of the valve?
- Valve diameter, that is, we often say 6 points valve, used in English units, with metric units should be DN20.2 points DN84 points DN156 points DN20 (3/4'')1 inches DN251.2 'DN321.5 'DN402 'DN502.5 'DN653 'DN804 'DN1005 'DN1256 'DN1508 'DN20010 'DN25012 'DN300Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.Because the units have metric (mm) and British (inch) distinction, there are the following methods of address.1., based on the metric system (mm), called DN (metric unit)2., on the basis of the British system (inch), called NB (inch unit)DN (nominal, diameter)NB (nominal, bore)OD (outside, diameter)
- 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:Z11H/Y forged steel gate valves H/Y what does that mean?SZ45H S what do you mean?Blow 2Z41YGY-40P, what do you think?What does NKZ61H vacuum valve NK mean?What does DS/Z64H water seal valve DS mean?Specific valve number how to see ah, detailed information, thank you!
- 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:Hydrant valve leaks, how do you close other valves? Specific steps?
- Crown valve pressFirst, make sure the front of the fire hydrant has a gate valve or butterfly valve Yes, it will be closed and replaced by the lineNo, then useSecond, the pressure of the pipeline to see how big, and if it is rare, replace it with water
- Q:What do O and S mean on the valve?
- Generally used in process valves, operating conditions required to open and close, especially in the case of pneumatic actuators installed, the loss of power and gas supply valve when the state
- Q:Who knows which kind of water valve is good?
- Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.
- Q:What is the normal temperature on the valve?
- 3. classification by operating temperature(1): ultra-low temperature valve for medium temperature of t< DEG C; 101 valve.(2): used for medium temperature valve operating temperature 101 C = t = 29 C valve.(3) at room temperature for medium temperature valve: the valve 29 <t<120 DEG C.(4) the temperature valve for medium temperature 120 = t = 425 DEG C valve(5) high temperature valve: valve used for medium temperature t>425 degrees celsius.If it helps, see it
- Q:Where is the valve used?
- Water treatment, chemical, petroleum, biological pharmacy and so on are more used
- Q:How to identify the good or bad of the valve, without pressure test and instrument?
- You can see what the material inside the valve ~ basically copper heart relatively durable, solid ~!
- Q:So how does the valve turn on?
- The handle of the valve is opened along the pipe and perpendicular to the pipe
