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.

Air Evacuation Valve with Solar Water Heater Exhaust Valves and Solar Water Heater Parts

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 are the main equipments for valve production?: Press machine, CNC lathe, instrument lathe, drilling machine, machining center, assembly line, pressure test bench, plane, measuring instruments, etc.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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q: The expert can tell me how to install this valve, and what fittings to use on both sides: It looks a bit like the butt weld butterfly valve. The two sides are welded to the pipe. There is a step on either side of the valve. Overhead welding

Q: Hydrant valve leaks, how do you close other valves? Specific steps?: Crown valve pressFirst, make sure the front of the fire hydrant has a gate valve or butterfly valve Yes, it will be closed and replaced by the lineNo, then useSecond, the pressure of the pipeline to see how big, and if it is rare, replace it with water

Q: Is the valve galvanized?: Butterfly valve gate, some hot-dip galvanized, and other valves are not.

Q: The valve is rusty and can not be opened. What shall I do?: There are pictures, for different valves, then choose different ways of opening.

Q: What is a heavy body valve?: You should be asking what a heavy-duty valve is.This is only in the ordinary gate valve and cut-off valve on the distinction. Nowadays, ordinary gate valves and cut-off valves are divided into heavy-duty ones. Medium and light three kinds ~!

Q: How big valves are used in a DN159 pipe?: DN159 is the valve with the DN150 in the outer diameter of the pipe.The valve size of the pipeline is classified by nominal diameter:1, the small diameter valve: nominal diameter DN = 40mm valve.2, medium diameter valve: nominal diameter DN from 50 to 300mm valve.3, chase diameter valve: nominal valve DN for 350 ~ 1200mm valve.4, large diameter valve: nominal diameter DN = 1400mm valve.The components of the valve must be handled following process before they are assembled:1, according to processing requirements, some parts need polishing, surface processing burr can not be;2. All parts are degreased;3, after degreasing, pickling and passivation, the cleaning agent does not contain phosphorus;4. After pickling, rinse with pure water, no residue of medicament, and carbon steel parts shall be omitted;5, one by one parts with non-woven fabrics dry, not cable, hair and other retained parts of the surface, or with clean nitrogen drying;6, with non-woven fabrics or precision filter paper, stained with pure alcohol, wipe parts by one, until there is no dirty color.

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.: If the valve from the opening and closing role, then the valve bore should be the same diameter with the pipe, big waste, small, increase resistance.If the role of the valve is adjusted, and that caliber will be different from the pipe diameter, this is not to reduce the cost of the problem, is a result of calculation, and this calculation results with flow, pressure drop and valve resistance curve.For example, control valve, usually smaller than the pipe diameter, such as pressure reducing valve, will be smaller than the pipe diameter to two.
