What is the special oxygen globe valve, how to choose?
In the laboratory or industrial production, a variety of gases, such as oxygen, nitrogen, hydrogen, etc., are often used, and the special oxygen globe valve is specially used to stop and control the flow in the pipeline conveying O2. So, what should you know when choosing and using special oxygen valve?
1. What is the special stop valve for oxygen
The special oxygen globe valve is usually used to control the high purity and high pressure O2. The most prominent chemical property of O2 is oxidation, so the material selection of the special oxygen valve must meet the requirements of oxidation resistance and corrosion resistance, and the highest material contains low C content. Oxygen special globe valve material is commonly used low carbon grade stainless steel, such as Austenitic stainless steel.
Special oxygen valve must be made through oil prohibition and degreasing treatment, antistatic treatment. The former is to prevent high purity O2 from oil explosion and fire; Antistatic treatment prevents friction from generating static electricity, which can lead to sparks, a dangerous thing to do at high pressure and high purity oxygen. In the process of use, the special oxygen valve must be strictly isolated grease, anti-static protection, in order to ensure the safety of use.
2. Pay attention to shopping
1) There are many kinds of special oxygen valves in the market, such as special oxygen reducing valve, special oxygen globe valve, special oxygen butterfly valve, oxygen control valve, etc. Specific consulting manufacturers, each manufacturer's products will be different.
2) Model and specification. According to the actual pipe diameter and use demand, select the appropriate specifications and models of oxygen valves.
The special oxygen globe valve is specially used for closure control in pipelines conveying high purity and high pressure O2. Safety and sealing should be paid attention to during the use of the valve, so as to ensure better use.
