The working principle and structure of stainless steel oxygen globe valves

Oxygen valve structure:

1 Globe valves structure in the form of the end, the end of the year, DC and rectangular. Straight through processing is the most common structure, but its fluid resistance.

2 DC resistance is a kind of liquid, containing solid particles or liquid viscosity. A forged angle body right, compared with the common way for small

The high pressure stop valve.

In the liquefied petroleum gas (LPG) in the reservation station, which is the oil refineries, chemical plants, petrochemical plants, liquefied petroleum gas, as a control valve used for lifting equipment.

Two, the working principle and structure

1 rotate the hand wheel clockwise, stem moves down, down to close the valve sealing surface, by cutting. The reversal is open, the highest point in the mentioned stem sealing work.

2 the valves is increased by a larger signs. There are two countries open the valve sealing, packaging and protective packaging layer.

3, the valve and the surface of the nylon products, the formation of filling filling sealing soft elastic material, good sealing performance.

Properties of oxygen valve closed

(1) simple structure, production of the door, and easy to maintain.

(2) the sealing surface is not easy to wear and abrasion, valves and valve sealing surface, open and close the sliding abrasion between the seal is good

Okay, good sealing performance, long service life.

(3) to open and close the valve stroke, thereby closing the valve height is less than the door, but the door structure.

(4) to open and close torque to open and close more effort, opening and closing time of directors.

(5) and the fluid resistance is small, the valve channel of communication, more twists and turns, small fluid resistance, energy consumption.

(6) when the common method of flow direction, downward nominal pressure PN ≤ 16MPa communication valve, pressure class under the guidance of the valve, the general use of communication management. In order to improve the seal. Cut-off media only one-way flow valve in use, you can't change the direction of water flow.

(7) the position is usually subject to erosion
