Structural characteristics of 1, the nominal pressure PN ≥ 1.6MPa, DNl25 ~ 200 used within the bypass structure; DN250 ~ 500 with a structure outside the bypass valve. Its aim is to reduce the valve before the valve after the pressure difference in order to avoid the high-velocity, high erosion, as well as to prevent the generation of high-temperature, oxygen in order to ensure the safe operation of pipeline networks, but also reduces the operating torque.
2, medium flow: PN ≥ 1.6MPa, DN ≤ 100 media from the valve below the top of the inflow valve (that is, low into the higher), DN ≥ 125 medium from the inflow valve to the bottom of Pu (high into the lower) o for the DN ≥ 125 using the valve into the lower medium high-flow bypass valve on the one hand, foot structure needs, on the other hand, as a result of media pressure forces the closure of the valve greatly reduced.
3, the valve has a guide of electrostatic safety devices to prevent sparks from static electricity.
4, compared with the general cut-off valve, oxygen valve line with part of the stent-wide enclosed structure, and packing can be pressed to open the protective cover on the stent, dust and oil have played a role. And a clear cut oil marker.
5, all the parts dealing with the use of strict skim.
