 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:Where is the valve used?
Oil and gas pipelines, gas stations, gas stations, petrochemical plants, water works,
Q:What does the "PN" mark on the valve mean?
The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
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:Which valves are used in the power station?
Power gate valve, also known as power station valve, is mainly used in various pipelines of fire power plants, cutting off or connecting pipeline medium.Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.Compared with other valve products, the gate valve of the power station is characterized by high temperature and high pressure. If only the pressure is lower than that of the universal valve, the temperature is lower than that of the general valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.
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
Q:What are the definitions of internal, external and leakage valves?
Outside leakage generally refers to the valve and connecting flange or threaded connection between the seal and guide...
Q:Who knows what the DE stands for in the valve DE50?
Nominal 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.De is the nominal diameter, that is, the outer diameterGenerally speaking, from small to large specifications are as follows de (mm)De20, de25, de32, DE40, de50, de63, de75, de90, de125, de110De160 de200 de250 de315...... Until de800
