 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:Which brand of electric valve is good?
Electric valve does not need to use imported, domestic boutique can meet.
Q:Is the filter also valve?
Filters are generally used in the pipeline, are ancillary products, strictly divided, it does not belong to the valve category
Q:How to check the quality of the valve?
First, visual inspection of the valve appearance, followed by a spectrometer to check the material, material, and then look at the hydraulic test pressure, whether there is leakage.
Q:What is the difference between a stop valve (a power station valve) and other valves?
The cut-off valve is low in and out of the structure, usually used in the case of pressure loss, the cut-off valve is not through the form. Gate valve is straight through type.
Q:What valve does the high pressure by-pass valve DN254 * 800 belong to?
This is because the bypass valve is a special valve and other valve type theory.This is custom-made valves, generally no inventory, and may not have the material you need. So it needs to be customized.I remember the German HORA had the valve, but the price was sky high.
Q:What does "TD671F" mean?
Refers to the pneumatic centerline of the clip butterfly valve, but I really do not know what the T represents what, but also may be some manufacturers own company's product specific model, do not understand.
Q:What is the difference between low pressure valves and medium pressure valves and high pressure valves?
According to the GB standard test pressure GB/T13927, "industrial valve pressure test" valve in accordance with the pressure can generally be divided into the following categories:(1) vacuum valve: refers to the working pressure is lower than the standard atmospheric pressure valve.(2): refers to the low pressure valve nominal pressure PN valve is less than 1.6Mpa.(3) medium pressure valve: refers to the nominal pressure of 2.5Mpa, PN, 4.0Mpa, 6.4Mpa valve.(4) high pressure valve: refers to the pressure valve PN 10.0Mpa 80.0Mpa valve.(5) super high pressure valve: nominal pressure PN = 100.0Mpa valve.Normally the stresses are actually pressure (force per unit area). Is generally used to gauge our living environment under 1 standard atmospheric pressure as reference 0 (reference point 0), and the difference between the value of the gauge (pressure gauge usually display is the gauge). But in fact we live in 1 atmospheric environment, coupled with the income of the 1 gauge pressure value is the absolute value of pressure.Standard atmospheric pressure actually has standard engineering atmospheric pressure at (kgf/cm2) and standard physics atmospheric pressure ATM, the former used in the early years, and now generally use the latter. 1atm=1.0332at=1.01325bar (bar) =101.325kPa=0.101325MPa.The valve pressure mainly focus on two parameters: rated working pressure, such as PN16, said the rated working pressure is 16bar (1.6MPa); the maximum permissible pressure difference (this value, the greater the actuator thrust torque required with the larger).
Q:What does "DN15" mean? What does "PN 16" mean?
Valve DN15 refers to the nominal diameter of the valve 15mm, PN, 16 refers to the pressure of the valve is 1.6MPa.Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter). DN is the nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of the general caliber. The pipes with the same nominal diameter can be connected with each other, so they are interchangeable. It is not the actual diameter or diameter of the pipe, although its value is close to or equal to the diameter of the pipe.
Q:What is the difference between the valve before the pump and the valve after the pump?
Pump front valve: current limit; pump rear valve: limit pressure.Pump operating procedures: the pump must be closed before and after the valve, open the pump, slowly open the pump front valve, pump pressure normal, slowly open the pump, valve until all open. If the pump is in front and rear valves are opened, the pump is very easy to burn the motor.
Q:What's the valve as a unit?
Generally used as a unit of measurement
