 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:Which direction is the valve? Which direction is it?
Ball valve: handle and Guan Daocheng 90 degrees for the pass, 180 degrees to open (ie in line with the direction of the pipe open)The gate: clockwise, counterclockwise.
Q:What is the BV valve?

Q:What is the difference between a stop valve (a power station valve) and other valves?
Power station cutoff valve advantages editor1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.2., simple structure, small size, light weight.3., reliable and reliable, the current gate valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., easy maintenance, simple valve structure, sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
Q:Our company is doing valve exports,
If the customs clearance order is required, the boxes, invoices, and contracts will not be needed. If the customs clearance is made, which port should be provided, the value of the goods, the weight, and the HS code for those
Q:Suddenly no water at home, asked about the property,
You should live in a high-rise, if there is no power failure, that is, the water tank pump failure, and urge property repair is.I hope I can help you
Q:What does the valve specification "3/4CL150" mean?
3/4 is the caliber, that is, DN20, CL150 is the pound, American Standard, and Kg is 16-20Kg.
Q:Who knows what the DE stands for in the valve DE50?
Back valve, DE50 balance valve, DE25 stop valve, DE75, what do you mean by "de"?Diameter DEThe diameter of a general plastic tube is indicated by DE in EngineeringNominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.
Q:Valve should be strictly marked according to the direction of instructions and media flow direction to determine the installation direction,
From the literal explanation, the strong counterpart connection is different from the normal connection. Valves are naturally connected to pipes or equipment, including threaded connections, flanged connections, clamp connections, welding, butterfly valves, clamp connections, etc..Strong mouth connection, similar to the butterfly valve on the clip connection, just outside of clamping method used in other valves (not seen on the clip connection with other valves), so this will depend on external interface of the valve (wafer type butterfly valve, said strong counterparts except).
Q:What's the caliber of the valve 1/4?
1 inches, =25.4 millimeters, 1/4 inches, =2/8 inches, =2 minutes, =DN8 (mm)3/8 inches =3 points =DN10 (mm)1/2 inches, =4/8 inches, =4 minutes, =DN15 (mm)3/4 inches, =6/8 inches, =6 minutes, =DN20 (mm)1 inches =DN25 (mm)1 1/4 inch =DN32 (mm)1 1/2 inch =DN40 (mm)2 inches =DN50 (mm)
Q:In the fire drawing, what valve does the following valve represent?
This is definitely the sprinkler system. It's a drain valve, a ready valve. You check it. I can't remember it. It has not been drained for a long time.
