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:How are the types of valves classified?
- In addition to the cylinder or hydraulic cylinder piston to drive, but also the use of pneumatic film driven, because of its small stroke and driving force, it is mainly used for regulating valves.Manual valveThe manual valve is the most basic way of driving the valve. The utility model comprises a hand wheel, a handle or a plate hand, and is driven directly and driven by a transmission mechanism two kinds. When the starting torque of the valve is large, it can be driven by gear or worm gear to achieve the purpose of omitting. Gear drive, spur gear drive and bevel gear drive. Gear reduction ratio is small, suitable for gate valve and stop valve, worm gear drive is relatively slow, suitable for cock flashing, ball valve and butterfly valve
- Q:Valve connections - two how do different connections work?
- The connection of two different connection forms is achieved by a transition conversion connector
- Q:How do you understand the valve Z41X-16?
- This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron
- Q:What is the use of each brand in the super high-rise, commercial complex, hotel? Price comparison of each brand? In the general valve, balance valve, electric valve, who did the best? Any knowledge about the valve, please ~ ~ thank you for your generous with your criticism
- Johnson, SIEMENS, Honeywell is mainly in the electric valve inside, because they themselves do automatic control system, so the electric valve matching is strong, but also manufacturers own production, other types of valves they several brands are generally looking for OEM agents do, is not recommended.
- Q:What are the most common types of valves?
- Gate valve, ball valve, butterfly valve, stop valve, these are the most common, but also the largest amount
- Q:Which valves are installed in a directional manner?
- There are balance valve, safety valve, pressure relief valve
- Q:Why is the valve on the pipeline not the same size as the pipe, and how much of a crude pipe can be given? Thank youI'm sorry, I didn't make it clear that when doing pipe work in the factory, for example, 60 of the pipe, and in this pipeline to install the valve to choose DN50, and so on.
- The valves on the pipe should be of the same size, which saves costs and reduces head loss.
- Q:What are the production equipment in valve shop?
- Gold processing equipment, such as cars, milling, drilling, grinding, slotting machines with little,Special equipment, welding machine, test press, grinding machine, painting line, shot blasting machineAuxiliary equipment, air compressor, grinder,
- Q:someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency
- You should live in a high-rise, if there is no power failure, that is, the water tank pump failure, and urge property repair is.I hope I can help you
- Q:What kind of valves are best used for sand drain valves?
- Looking at the domestic sand discharge conditions, the more commonly used plate valve and butterfly valve these two, but generally reflect the service life is not long, it will not be long before the sand leakage, the need for regular maintenance, low efficiency, affecting production. In recent years, the industry has also appeared in various kinds of new type of valve, take little effect, but also has a valve using the excellent response, talent shows itself, long service life, no maintenance, model for the special valve industry Yu powder FQD672 and FQD643,It is understood that the valve industry has been to focus on Yu powder (sand) on body condition, especially the delivery of viscous pneumatic conveying system, special valve type FQD672 and type FQD643 powder successfully developed specifically for the design of sand material conditions, erosion resistant, anti adhesive seal design, automatic compensation, to ensure zero leakage absolutely, efficient and longevity, is applied to the resin sand casting industry (coarse sand) sand core shape of the high-speed exhaust conditions, you can try to understand Baidu......
