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

Air Evacuation Valve with Solar Water Heater Exhaust Valves on Sale from China

Q: Which industries need valves?: 3., the other side of energy development is energy conservation, so from the perspective of energy conservation, it is necessary to develop steam traps, and to sub critical and supercritical high parameter development;4., the construction of power stations to large-scale development, so the use of large diameter and high pressure safety valve and relief valve, but also need to quickly open and close the valve;5., for the needs of complete sets of projects, the supply of valves from a single species to more varieties and specifications. The valve required for an engineering project is growing with the full availability of a valve manufacturer.In the next few years, the overall trend in demand for the valve for the upward trend, the valve of this large volume of industrial supplies, its demand in steady growth. Among them, the demand for a larger number of valves in turn are: ball valve (15.5%), cut-off valve (12.9%), safety valve (12.5%), gate valve (12.5%), butterfly valve (10.6%), regulating valve (8%) and check valve (6.1%).

Q: 1/2, what does 1/4 valve mean? I don't understand. What does this number mean? Have a valve to introduce me, do not copy a pile of online introduction, I want to concise: Valve international universal caliber national nominal diameter1/4 inches, =2/8 inches, =2 minutes, =DN8 (mm)3/8 inches =3 points =DN10 (mm)1/2 inches, =4/8 inches, =4 minutes, =DN15 (mm)3/4 inches, =6/8 inches, =6 minutes, =DN20 (mm)1 inches =DN25 (mm)1 1/4 inch =DN32 (mm)1 1/2 inch =DN40 (mm)2 inches =DN50 (mm)

Q: The valve is rusty and can not be opened. What shall I do?: Remove the handle and lever the stem rotation with a wrench,

Q: What are the production equipment in valve shop?: CNC machining center, double control vertical lathe, CNC lathe, CNC machine tools, heavy vertical double column lathe, spherical lathe horizontal boring machine, surface grinder, cylindrical grinder, lathe, milling machine, hydraulic head full bed, gate valve grinding machine, grinding machine, lathe, radial drilling machine,Powder plasma arc welding machine, thyristor rectifier, DC DC arc welding machine, welding machine, drying machine, trolley type resistance furnace, hook type shot blasting machine, medium pressure compressor, crane, pneumatic label printer, printer, compressed air sprayer spraying water line, air pressure box type resistance furnace. Forklift lifting platformLow temperature test equipment, metal and low temperature impact test machine, quantitative spectrometer imported carbon sulfide analyzer, microcomputer analyzer, spectrum analyzer, X-ray flaw detector X-, permeability detector, magnetic particle detector, ultrasonic thickness meter, digital ultrasonic flaw detector, metallographic microscope, hardness tester, precision analysis balance (hydraulic material testing machine), hydraulic valve testing machine hydraulic valve testing machine, submerged valve testing machine, steam trap test machine, valve testing machine, pressure testing machine temperature test machine

Q: What's the name of the valve?: This is the discharge valve, the lower part of the handle protruding part of the valve is the sealing device. The overall material should be brass, which is typically made by equipment manufacturers.

Q: The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.: Are you talking about using air? Or your valve is a pneumatic emergency shut-off valve

Q: How to better maintain the valve?: Use and maintenanceThe maintenance of the aim is to extend valve life and ensure reliable opening and closingThe stem threads, often with the stem nut friction, to a little yellow dry coating oil, molybdenum disulfide or graphite, lubricationWe do not often open and close the valve, but also on a regular basis handwheel on the stem threads to add lubricant to prevent bitingThe outdoor valve, to increase the protection sleeve on the stem, to rain, snow, dust and rustIf the mechanical valve system to be fixed, to add time to the gearbox oil

Q: How can the material be checked by valve approach? What experiments do you need?: (8) the throttle valve does not test the tightness of the closing parts, but the strength test and the tightness test of the stuffing and the gasket shall be carried out.(9) the pressure test, the valve closing force only allows a person's normal physical strength to close; not augmented with tools like leverage (except torque wrench), when the hand wheel diameter is greater than the wait at 320mm, allowing two common off.(10) with a sealed valve, should be taken out of packing for sealing test, sealed after the official closed, check whether leakage. When gas is used as a test, check the water in the stuffing box. When sealing test is carried out, the upper seal is not allowed to be in the tight position.(11) when the valve with drive device is tested and its tightness is tested, the sealing test shall be carried out by using the driving device to close the valve. For manual drive units, seal test shall also be done with the actuating closing valve.(12) the by-pass valve installed on the main valve after the strength test and the sealing test. The strength and tightness test of the main valve is carried out. The main valve should be opened when the closing member is opened.(13) iron valve strength test, the application of Pratia tapping valve and valve cover, check whether there is any leakage.(14) the valve test, in addition to the provisions of the plug valve to allow sealing surface oiling, other valves are not allowed in the sealing surface of the oil test.(15) when the valve pressure test, the blind plate on the valve pressure should not be too large, so as to avoid deformation of the valve, affecting the test results (cast iron valve if pressed too tight, will be damaged).(16) after the valve test pressure, should promptly remove the water and clean the valve, should also be prepared for the test record.
