 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

Q:What do the Z, J, H and D represent in the valve type?
Valve type code Z, J, L, Q, D, G, X, H, A, Y, S, respectively:Gate valve, globe valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, pressure reducing valve and steam trapThe connecting codes for valves are 1, 2, 4, 6 and 7, respectively:1, internal thread, 2, external thread, 4, flange, 6, welding,
Q:What does the RF of the valve mean?
The RF of the valve represents the form of the sealing surface, which means: protrusion.
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 does 3/4''mean in the name of the valve?
Valve diameter, that is, we often say 6 points valve, used in English units, with metric units should be DN20.2 points DN84 points DN156 points DN20 (3/4'')1 inches DN251.2 'DN321.5 'DN402 'DN502.5 'DN653 'DN804 'DN1005 'DN1256 'DN1508 'DN20010 'DN25012 'DN300Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.Because the units have metric (mm) and British (inch) distinction, there are the following methods of address.1., based on the metric system (mm), called DN (metric unit)2., on the basis of the British system (inch), called NB (inch unit)DN (nominal, diameter)NB (nominal, bore)OD (outside, diameter)4. [case]Galvanized steel pipe DN50, sch 20Galvanized steel pipe "NB2", sch 205., the outer diameter and DN, NB relationship is as follows:------DN (mm), --------NB (inch), -------OD (mm)15-------------- 1/2--------------21.320--------------3/4 --------------26.725-------------- 1, ----------------33.432-------------- 1, 1/4, -----------42.240-------------- 1, 1/2, -----------48.350-------------- 2, -----------60.365-------------- 2, 1/2, -----------73.080-------------- 3, -----------88.9100-------------- 4, ------------114.3125-------------- 5, ------------139.8150-------------- 6, ------------168.3200--------------- 8------------219.1The above data is referenced only in ASTM A53. Please note that there are some differences in external diameter with different specifications.
Q:How are the types of valves classified?
Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion.
Q:How to suppress the valve?
How does the valve press the pressure test pump?. How much pressure do you need to use the pressure pump for the corresponding specifications?. There is a specially suppressed machine pressure test pump. How much pressure do you need to use the pressure pump for the corresponding specifications?
Q:How to identify a good or bad valve?
You can see what the material inside the valve ~ basically copper heart relatively durable, solid ~!
Q:High and low pressure valve is how to distinguish?
Ultra high pressure valve nominal pressure PN = 100MPa; high pressure valve nominal pressure PN10.0MPa ~ 80.0MPa; medium pressure valve, nominal pressure of PN2.5MPa ~ 6.4MPa; low pressure valve, nominal pressure PN is less than or equal to 1.6MPa
Q:What's the difference between a valve and a valve?
The correct unit should be called "group". A set of threaded valves include valves, live connections, and short tubes. A set of flanged valves consist of a pair of flanges (including bolts, gaskets, rubber pads), and short tubes".
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
