 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.

Q:Can the gas valves be switched off regularly?
Now gas stoves have valves, do not have to pass the gas valve, valve, he has the life of the use of frequency, although the switch is not good, long time no operation is not good
Q:How do you calculate the flow of the valve?
Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
Q:How do I open the gas valve?
Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all. 1, according to the routine, now the handle position shows that the valve is open. 2, if the handle rotated 90 degrees, the gas pipeline gas has no change, should be the stem slipped, can not drive the valve ball rotation. Try rotating several times. If it still doesn't work, ask a professional to check it out.
Q:What kind of industry does valve belong to?
Valves are machinery and industry equipment;Valve belongs to general mechanical equipment
Q:G what's the meaning of the valve?
Valve with other function or with other special mechanism, fill in a Chinese language before the valve type code number
Q:Which industries need valves?
Valve as a general component, widely used in various industries, but there are three main purpose of application in various industries:1, routine inspection needs;2, new projects supporting;3, emergency reserves.Valve market trendsDue to changes in user demand, the market trend of valve products will also change accordingly. In the future, the main trends are as follows:1 with the transfer of oil development to the mainland oil fields and offshore oil fields, and the power industry under the 300 thousand kilowatts of thermal power to more than 300 thousand kilowatts of thermal power and hydropower and nuclear power development, and valves should be changed based on device applications and the corresponding changes in its performance and parameters;2 urban systems generally use a large number of low-pressure valve, and to the development of environmentally friendly and energy-saving, low iron gate that is used in the past gradually shifted the environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and the center line butterfly valve seal transition, oil and gas pipeline projects to develop in the direction, which in turn requires a large number of flat gate valve and ball valve the;
Q:The valve of the solar energy was broken by me. Do you know what is called?
An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.
Q:What is a lift rod valve?
The valve stem and valve plate are relatively fixed, and the valve stem rises up when the valve plate is raised
Q:What does the valve stroke mean?
The distance from one position to another. Usually in the first position of the cut position, the second position is put through the position. Unless the valve has 3 positions.
Q:What are the technical requirements of valves, such as "Z15W-25T"?
The first Z represents the gate valve;The second bit is omitted, indicating the handle or handwheel;Third bit 1, indicating internal thread connection;Fourth bit 5, indicating dark wedge rigid single gate;Fifth W, which means the sealing materials are the main body material of the valve;The second paragraphThe first 25, said the nominal pressure is 2.5MPa (valve used in accordance with the pressure level of GB/ 1048, the use of GB/T 1048 standard 10 times the unit of MPa (MPa) value, otherwise the unit value is MPa. If it is a power station valve, the unit value is MPa.)Second bit T indicating copper and copper alloy for the valve body.
