 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.

Q:Pump, valve, these belong to the material?
Pumps, valves are electromechanical equipment, belonging to a class of hardware fittings, but not material!
Q:What's the difference between valves and valves without valves?
The advantage of carrying valves and venting valves is that they control the amount of exhaust and prevent other fluids from flowing out.
Q:How about the valve?
In 1998 began the formal production of valves. As the company expanded in size, in September 2003, changed its name to the British HV VALVES LIMITED (HUDDERSFIELD), referred to as the United kingdom. The design and production of various types of valves, widely used in power, oil, chemical, offshore platforms and other fields, with its excellent quality and service to win the praise of the vast numbers of users.
Q:What does the ZH41 valve ZH41 mean, and what other specifications?
Is the model wrong? The correct one should be Z41HGate valve, hand flange connection name, rod type single gate, sealing surface is alloy steel
Q:Who knows which kind of water valve is good?
Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.
Q:What valve is the DN 25?
This is only the aperture of the valve. It does not represent the form of the valve.
Q:Internal structure of valve
To answer your question was the top valve is not open on the thread of an analogy between ordinary wood screws and nails is a straight out of another can only rely on the screwdriver to turn out the cut-off valve is from the mechanical analysis of text as a specific principle is not specific
Q:What does the RF of the valve mean?
The valve sealing surface in the form and code summary: sealing surface - RF - plane surface process FF ring joint face - RJ - TG groove convex surface - MFM applies to the following: PL flat plate flange hubbed welding neck flange with SO WN IF socket SW screw flange butt welding Th ring loose PJ/SE welding-on collar loose PJ/RJ flange cover BL lining flange cover BL (S) American Standard hubbed SO American Standard wn WN
Q:What valves are needed on the construction site?
Order valves1, according to the use of place, use, and understand the relevant laws and regulations, specifications, standards, policies, approval may be used after the selection of valves suitable for various requirements;2, confirm the working conditions of valve, applicable medium, working pressure and medium temperature;3, determine the nominal diameter corresponding to the pipe: DN (mm), NPT, NPS (");4, determine the way to connect with the pipe: flange type, internal (external) thread type, welding type, clamp type, clamp type, card sleeve type, etc.;5, determine the valve operation mode of driving: manual, worm gear drive, pneumatic, electric, hydraulic, electromagnetic, electro hydraulic, etc.;6, confirm the types of valves: gate valve, globe valve, throttle valve, plunger valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, drain valve, pressure reducing valve and other special valves;7, determine the use of valves: switching type, adjustment type, safety type and so on;8, determine the valve shell and internal parts of the material: carbon steel, alloy steel, stainless steel, ductile iron, gray cast iron, copper alloy, aluminum alloy, plastic and so on;9, determine the valve sealing performance requirements, sealing level or sealing leakage;10, determine the valve coating requirements, packaging requirements, transportation requirements;11, special needs of the valve should also be determined: structure length, valve height, appearance size, flow resistance, emission capacity, flow characteristics, protection level, explosion-proof performance and other parameters;12, determine the valve installation position and posture.
Q:What does valve 41F-40C mean?
Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C
