The use of unloaders should follow the following rules:
(1) the action must be slow when the oxygen cylinder is deflated or the pressure reducer is opened.If the valve is opened too quickly, the temperature of the air in the decompression part is greatly increased due to adiabatic compression, which may cause the parts made of organic materials such as rubber packing, rubber film fiber gasket to burn out on fire, and may cause the decompression to burn out completely.In addition, due to the rapid discharge of static sparks and pressure reducer has oil, etc., will also cause the fire to burn the pressure reducer parts.
(2) precautions before installation and opening cylinder valve: before installation of the reducer, slightly beat the cylinder valve door to remove dirt and prevent dust and moisture from taking into the reducer.When opening the cylinder valve, the outlet of the valve should not be aligned with the operator or others to prevent the high-pressure gas from rushing out and injuring people.The joint between the air outlet and the gas rubber hose of the pressure reducer must be tightened with the iron wire or clamp;Prevent the danger of release after air supply.
(3) precautions during loading and unloading of unloader: when loading and unloading of unloader, attention must be paid to prevent screw slipper of pipe connector, so as to avoid injection due to unsecured screw assembly.In the process of work must pay attention to observe the pressure value of the working pressure gauge.When stopping work, loosen the pressure-regulating screw of the reducer, and then close the oxygen cylinder valve, and slowly exhaust the gas in the reducer, so as to protect the spring and pressure-reducing valve from damage.At the end of the work, the pressure reducer should be removed from the cylinder and stored properly.
Good Service We are committed to providing the best service! We can also customize for you. If you are interested in our products or you have any ideas about us, please feel free to contact us and we will make sure all your approaches will be dealt with professionally and promptly!
Q1. What products can you provide? Answer: High pressure regulator, cylinder gas regulator, ball valve, needle valve, compression fittings(connections).
Q2. Can you make the products based on our requests, such as connection, thread, pressure and so on? Answer: Yes, We have experienced techincal team and can design and produce the products according to your requirements. Take a pressure regualtor for example, we can set the range of pressure gauge according actual working pressure, if the regulator is connected to a gas cylinder, we can add an adaptor such as CGA320 or CGA580 to connect the regulator with the cylinder valve.
Q3. What about the quality and price? Answer: Quality is very good. Price is not low but pretty reasonable at this quality level.
Q4. Can you provide samples to test? For free? Answer: Of course, you can take several to test firstly. Your side shall bear the cost due to its high value.
