 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:Several problems about valve parameters
Is the flow through the valve. That is to say, when the valve is fully open, flow through the valve size.
Q:Is the valve galvanized?
Butterfly valve gate, some hot-dip galvanized, and other valves are not.
Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
The use of the same difference, you can see the shape
Q:Standard and specification for pressure test of valves
Welcome to Beijing Shan'er pipeline control components Co. Ltd. consulting
Q:I want to act as a proxy valve
As the saying goes, the valve does not break up. The type of valve is too much, I do not know what you want to proxy valveIf you want to take advantage of the price, please go to Tianjin, or go to the township of Henan valve to see the followingIf you want to take advantage of quality, please go to Henan's Gaoshan Valve Co., Ltd., Yu Ming Valve Co., Ltd., Zhengzhou high and low pressure valve Co., Ltd... I am the valve distributor in Shenyang
Q:How does the valve rust die?
The treatment of valve rust is as follows:1, use corner grinder cut off valve, and then a small mill grinding wheel cutting residual film cut pipe installed in the screw part, when the attention of cutting depth.2, with the amount of hydrochloric acid corrosion and rust of the valve, until the rust completely removed, rinse with water.3, on the newly purchased valve galvanized, can effectively prevent rust.Valve (Famen) 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.
Q:What is the normal temperature on the valve?
At normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
Q:What does LBC mean in a valve?
Z: gate valve6: connection form for welding1: wedge type single gateY: the sealing surface is cemented carbide800LB: nominal pressure is 800 poundsP: the valve body is made of chrome nickel stainless steel20: nominal diameter is 20 millimetersLB refers to the nominal pressure of the valve, how many pounds, C, P refers to the body material, C refers to carbon steel, and sometimes can be omitted
Q:How does the valve close?
Rotate it, turn it clockwise. Spherical valve, then hit a cross shaped on the line.Valve (Famen) is a control component in the fluid delivery system.

Q:What is a lift rod valve?
Lever valve stem nut in the valve plate, it with the disc (hand wheel) to open the turn, its stem pull the valve head and higher than the valve disk, also known as the bar valve. It is different from the dark rod valve, dark rod valve stem nut in the valve body, when the disc rotates, the stem will not rise.
