 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

Table 10 the sealing surface of the valve seat sealing surface or liner material code or liner material code sealing surface or lining material code or code of lining material tin based bearing alloy seal (Babbitt) B Monel M alloy T enamel C nylon plastic rubber X N steel boriding nitriding steel D P hard alloy Y fluorine plastic lining F lead Q ceramic G austenitic stainless steel R Cr13 stainless steel H S note: the plastic body directly processed seat sealing surface material code with "W". When the sealing surface of the sealing material is not the same, the material name is indicated by the material with low hardness. The value of the nominal pressure of 10 times, according to the number of MPa (1MPa=106Pa). The valve body material code represented by the letter, in accordance with the provisions of table 11. Table 11 the valve body material body material material code code code C chromium nickel molybdenum stainless steel R Cr13 stainless steel H S plastic steel chromium molybdenum copper and copper alloy I T malleable cast iron titanium and titanium alloys K A L Aluminum Alloy CrMoV V Cr Ni stainless steel P Z gray cast iron ductile iron Q. In the original standard of nominal pressure equal to or less than 1.6MPa gray cast iron and the nominal pressure is greater than or equal to 2.5MPa carbon steel valve omitted the code.
Q:What is the main function of the valve?
Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. 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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:What are the other valves used for the control of dual-use items?
This is the export licence for dual-use items and technologies.The electronic key issued by Beijing is only qualified for this certificate.We can do that
Q:Is there a one-piece, two linkage valve?
Yes, three ball valves (T and L) are two. Switch more complex point of the valve is basically ball valve, such as central air-conditioning commonly used to the four - way reversing valve.
Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
Q:Remove the handle and lever the stem rotation with a wrench,
Monel alloy is mainly applied to the valve in the medium containing hydrofluoric acid.6, Hastelloy alloy is mainly used in the valve of strong corrosive medium such as dilute sulphuric acid7, titanium alloy is mainly applicable to all kinds of strong corrosive medium valveRecommendations for the GB standard of steel and ASME second A copies at American Standard. For American Standard steel can also see ASME B16.34
Q:What is the flow medium of the valve?
Just like the one in your bottle, then the medium in your bottle is water
Q:What is the difference between a stop valve (a power station valve) and other valves?
High pressure, special material, complex structure, seldom manual operation.
Q:The water pipe in the house is broken.
In general, a unit has a total valve. From this start, find it, find a less water when passing the total valve home to change, more energy, save trouble later. Or find the person of the company to deal with tap water.
Q:How to quickly identify the types of valves?
There are many kinds of valves, such as butterfly valve, ball valve, globe valve, gate valve, check valve, plug valve, plunger valve and diaphragm valve...... Pneumatic, electric, worm, or handle......There are also pictures on the Internet, you can search their respective pictures, shape is visible
