100mm Explosion - Proof, Anti - Flow, Anti - Fall Eight Heavy Insurance Series Decompressor Pressure Reducer

Explosion - proof, anti - flow, anti - fall Eight heavy insurance series decompressor,pressure reducer

 Performance is introduced

 For medium gas flow requirements, including gas welding, cutting, etc.
it also applies to industrial manufacturing, agricultural maintenance,
laboratory testing, medicine, health, electronics industry and so on.

 Matrix, front cover

 All of them are forged by high quality brass, with the front cover under
pressure of 16MPa.

 The front cover is made of high quality rubber diaphragm and high purity
stainless spring to make the pressure adjustment smoother and smoother.

 The air inlet joint is equipped with a new type patent for dialysis.

 The pressure gauge is subjected to 25, 000 fatigue tests, with a built-in buffer
and a protective sheath.

 It has two anti-insurance, 8 heavy insurance functions:

 Explosion-proof security

 Safety valve overload fuse one insurance.

 Deflated hole pressure 2 insurance.

 Head shock buffer 3 insurance.

 The contact nut does not crack four insurance.

 Antigravity function

 Dialyzed gas 5 insurance.

 Ultrasonic vacuum cleaning 6 insurance.

 Decompression spring no rust 7 insurance.

 Defensive function, eight insurance protection cover

 Accord with Korean KS, comply with UL safety standard.

 The use of the decompressor should be performed as follows:

 (1) the action must be slow when the oxygen cylinder is released or the
pressure reducer is opened.
 If the valve opening speed too fast, working pressure reducer parts of
the gas temperature because of adiabatic compression, and greatly
improved, so has the potential to parts made of organic materials such
as rubber filler, rubber film fiber liner fire burn out, and can make the pressure
reducer completely burn out.In addition, due to the excessive discharge of the
electrostatic spark and the pressure reducer, such as oil pollution, also can cause
ignition to burn the decompressor parts.

 (2) precautions before installation and opening of the cylinder valve: before
installing the pressure reducer, use the valve door to blow out the dirt to prevent
dust and moisture from being brought into the pressure reducer.
 When opening the cylinder valve, the valve outlet must not be aimed at the
operator or other person, in case the high pressure gas suddenly burst out of
the person.
 The outlet of the pressure reducer must be tightened with a wire or clamp that
is overfired.
 It is dangerous to take off after air supply.

 (3) matters needing attention during the loading and unloading of the decompressor
and the handling of the decompressor must be paid attention to prevent the thread
of the pipe joint from slipping, so as to prevent the slipping of the screw.
 It is necessary to observe the pressure value of the work pressure gauge during the
working process.When stopping work, loosen the pressure screw of the decompressor,
then close the oxygen cylinder valve, and slowly release the gas in the pressure reducer
so that the spring and pressure relief valve can be protected from damage.

 (4) the pressure reducer must be fixed regularly, and the pressure gauge must be
inspected regularly.This is done to ensure the reliability of the pressure adjustment
and the accuracy of the pressure gauge reading.In the use of such as the detection
of air leakage, pressure, pressure, and so on, should be repaired in time.

 (5) treatment of decompressor freezing.In the process of use, the pressure reducer
is frozen, thawed with hot water or steam, and must not be roasted with flame or
red iron.
 When the pressure reducer is heated, the residual moisture must be blown off.

 (6) the reducer must be kept clean.The pressure reducer should not be contaminated
with grease or dirt. 

 (7) all kinds of gas pressure reducers and pressure gauges should not be replaced.
For example, the decompresser used for oxygen cannot be used in acetylene, LPG
and other systems.

 
 We are the specialized manufacturer and supplier of pressure gauges,
regulator and welding torch .
 During our 25 years in the industry,we have managed to earn over
100 patents in mainland China, setting our products apart from those
