Valve for JY41 oxygen pipeline is according to the operation characteristics of oxygen pipe network and considering the characteristics of oxygen medium flammable, safe and reliable and superior performance for the design principle, and with reference to the People's Republic of China Ministry of metallurgical industry to develop "Oxygen safety regulations" regulations and design and manufacturing to ensure the safe operation of the special valve oxygen pipe. The main material is made of stainless steel or copper alloy excellent flame resistance, sealing surface of the body or welding D802, other internal parts of stainless steel or copper alloy; lubrication transmission parts with grease non flammable, and marked a clear ban on oil mark. In the structure, the bracket adopts full closed seal, and has an electrostatic removing device, and the valve stem is provided with a dust-proof cap.
Order note:
If there is no selected model, please provide detailed parameters, such as medium, temperature, pressure, caliber, material and so on. Our technicians will select for you
Two. Provided that the selected model is available according to the selected model
Three, non standard products need to provide samples or confirmed by drawings
Note: the information is for reference only, or incomplete, so please feel sorry for the inconvenience. The company can choose according to different requirements and parameters. The company has a variety of sizes, pressure, different materials, connections, drive mode, to meet the different needs of various types of gate valve. Please contact 021-6651 8677 or consult online.
1. Internal bypass structure is adopted for nominal pressure PN≥ 1.6mpa and DNl25 ~ 200; DN250 ~ 500 adopts external bypass valve structure. The purpose is to reduce the pressure difference between front and back of the valve to avoid high flow rate, high scour and high temperature, thus ensuring the safe operation of the oxygen network and reducing the operating torque.
Flow direction of medium 2, PN acuity 1.6 MPa, DN acuities were below the 100 medium by the disc into the disc above (i.e., higher than that of low into), DN 125 medium by disc BuFang inflows or below (high in low out) o for DN 125 valve adopts medium or high in low flow, on the one hand, foot in the need of by-pass valve structure, on the other hand, due to the effect of medium pressure valve closing force greatly reduced.
3. The valve is equipped with a safety device for conducting static electricity to avoid sparks caused by static electricity.
4. Compared with the ordinary globe valve, the bracket part of the globe valve for oxygen pipeline adopts a completely closed structure, and the protective cover plate on the bracket can be opened when the packing is pressed, so as to prevent oil and dust. And has the obvious oil prohibition mark.
5. All parts shall be degreased strictly.
