YJ41FPN16~40- Oxygen stop valve is widely used in steel, metallurgy, petrochemical, chemical and other oxygen engineering pipe network. In addition to the function of ordinary valves, this type of product has its own characteristics. Strict oil prohibition measures during manufacturing, and parts are strictly degreased before installation. It is mainly used to connect or cut off the medium in the pipeline, generally not to adjust the flow rate, and the applicable pressure range is very wide. It is a valve specially designed for oxygen pipe network, widely used in steel, metallurgy, petrochemical, chemical and other oxygen engineering pipe network.
Structural characteristics
1, for nominal pressure PN≥ 1.6MPa, DNl25 ~ 200 internal bypass structure; DN250 ~ 500 with external bypass valve structure. The purpose is to reduce the pressure difference in front of the valve and behind the valve to avoid high flow rates, high scour and prevent high temperatures, thus ensuring the safe operation of the oxygen network and reducing the operating torque.
2. Medium flow direction: PN≥ 1.6MPa, DN≤100 medium flows from the bottom of the valve disc into the top of the valve disc (that is, low entry and high), DN≥125 medium flows from the valve disc square into the bottom (high entry and low exit)o For DN≥125 valve medium high entry and low exit flow, on the one hand, the internal bypass valve structure needs, On the other hand, due to the effect of medium pressure, the closing force of the valve is greatly reduced.
3, the valve is equipped with electrostatic safety device, can avoid electrostatic spark.
4. Compared with the ordinary stop valve, the support part of the stop valve for oxygen pipeline is fully enclosed, and the protective cover plate on the support can be opened when the packing is pressed, which plays the role of oil and dust prevention. And there is a clear oil prohibition mark.
5, all parts of strict degreasing treatment.
