Oxygen dedicated ball valve Oxygen turbine ball valve YQ341F

Date:[2016-10-20]    hits: Oxygen dedicated ball valve Oxygen turbine ball valve YQ341F

Oxygen turbine ball valve YQ341F

Nominal diameter: DN15-600

Nominal pressure: 0.6Mpa-4.0MPa

Applicable temperature: ≤ 150oC

Applicable medium: oxygen, nitrogen and so on

Inspection standard: JB / T9092-89

Body material: 0Cr18Ni9

Structure length: JB, GB, ANSI, BS, API, ISO, DIN, NF


Oxygen valve characteristics: the main features

1, the valve mainly by the valve body, bonnet, valve and other parts of the spherical valve body, even force.

2, the valve for manual operation, clockwise hand wheel, the valve is closed, counterclockwise rotation hand wheel, the valve opens.

3, DN50 the following ball bearings, DN150, DN200, DN300 and other large-caliber valve additional valve flap. Media flow from the top of the valve flap to the bottom.

4, in order to achieve good sealing performance in the structural design to guide the movement of the valve so that it can accurately fall on the valve seat, the valve flap in the body-oriented, the valve by the lateral flow of medium driving force , By the valve body and not by the stem to bear, which further increases the sealing performance and the possibility of packing seal.

5, the stem is designed to lower the stem, that is, when the stem does not turn when the lift, the valve with its movements, once again reducing the valve seat in motion and the friction seat to reduce the wear of the filler, while the seal wear may Reduced to a minimum.

6, in the body of the flange on the ground bolts are equipped with a bolt to be connected by wire to avoid sparks caused by static electricity explosion, the exposed parts of the stem are protective measures to prevent dust and oil , Stent bearings lubricated with fluorinated grease, frame frame installed plexiglass cover, there is a clear "ban oil" mark, to remind the attention of the scene.


First, the stainless steel ball valve oxygen Features:

Oxygen valve as the metallurgical industry in the delivery of oxygen pipeline on the opening and closing devices, compared to other common valves have many particularly stringent requirements. Because oxygen is flammable and explosive dangerous goods, it is necessary to prevent leakage, anti-static, anti-sparks, in order to avoid accidents. In the structure, the design is: valve stem open and close only when the stem does not rotate, effectively reducing the wear of the seal, packing wear and wear on the seal; side flange is equipped with grounding screws, to avoid static sparks; stem The exposed part of the sealed with plexiglass cover, to dust and oil. Technical parameters Valve body material 1Cr18Ni9Ti Nominal pressure PN (MPa) 2.5 Nominal diameter DN (mm) 15-400 Performance Description Features With a sealing performance, light and flexible operation, safe, reliable, long life and other advantages.
