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.

Customers’ Guidance:
Please leave the following info in inquiry
1. What’s the raw material ( carbon steel or stainless steel )
2. What’s the entrance diameter( 508 mm /273 mm or customized)
Because with these factors, we are able to give you a fast answer.
- Q:The difference between fire general valve and fire fighting special valve
- Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.
- Q:What's the advantage of using three way valves?
- A valve can be used to turn on and off and change the flow direction of the medium.
- Q:Look at the flow chart, some of the valves are marked with FV, and some are marked with XV. What does that mean?And what do you mean by the Cv value on the valve nameplate?I hope the heroes give a clear explanation ah, it is best to give an introduction of this knowledge of the web site oh.Thank again.
- Is the flow through the valve. That is to say, when the valve is fully open, flow through the valve size.
- Q:How to better maintain the valve?
- How to maintain the valve?Enter the same as other mechanical products, but also the need for maintenance. This work well, can extend the service life of the valve, the following will introduce the valve maintenanceStorage and maintenanceThe maintenance of the purpose is to keep the valve in the custody of the damage, or lower quality. In fact, improper storage is one of the important reasons for valve damageThe valve custody, should be arranged in good order, a small valve on the shelves, large valves can be neatly arranged in the warehouse on the ground, not arbitrary lumber pile, do not let the flange face contact with the ground. This is not only for beauty, mainly to protect the valve, not to touch badBecause the storage and handling properly, hand wheel broken, crooked stem touch the fixed nut hand wheel and stem loosening loss and so on, these should avoid unnecessary losses.We temporarily on the short-term use of the valve, should remove the asbestos packing, in order to avoid electrochemical corrosion damage to the valve stem.I just entered the library on the valve, to conduct inspections, such as during transport into the water or dirt to wipe clean, re storedThe import and export of valves to use wax paper or plastic sheet sealed to prevent dirt insideThe valves on the machined surface rust in the atmosphere should be coated with anti rust oil, protectI placed outside the valve, must be covered with linoleum or tarpaulins like rain, dust items. Keep the storage of the valve clean and dry
- Q:Valve category can fill the trunk door, branch valve Mody?
- Valve category refers to the type of valve, the big species are divided into: butterfly valve, gate valve, globe valve, ball valve, check valve, control valve, trap and electric valve,
- Q:What are the key valve enterprises in China? Mainly in those areas?
- Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same
- Q:Is there any difference between the valve and the water valve?
- There is no difference between the low pressure lubricating oil pump, as long as the excuse right on the line, not to pressure, design pressure ball valve common does not exceed 3MP, the maximum pressure of only small gear pump vane pump is 2.5MP, the other piston pump, gear pump, the pressure is above 6.3MP. Certainly not. Unless using high pressure water pipe valve.
- Q:What does the whole copper valve mean?
- Except the handwheel, all the material of the valve body is copper
- Q:Representation of several types of valves
- Valve body material:Z grey castings (usually not shown)X malleable ironQ nodular cast ironT copper alloyB lead alloyII chromium molybdenum alloy steelL chrome alloyP chromium nickel steelV (II) chromium molybdenum vanadium alloy steelR cr.ni.mo.ti steelF fluoroplasticP leather (Shen Penggang)S plasticD nitrided steelCJ lining adhesiveTC magnetic boringCS lined plasticCQ lined with leadW sealing ring is machined from valve body, C carbon steel (generally not shown)G ferrosilicon
- Q:What is the KVS in the valve parameter?
- KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
