The globe valve refers to the valve that the closing part (valve disc) moves along the axis of the seat, and the globe valve is mainly used for cutting off the pipeline. Because the seal is reliable, the opening and closing stroke is short, the pressure on the valve stem directly presses the sealing surface, and there is almost no friction on the sealing surface when sealing, so the vacuum valve is often used as a stop valve. Generally, there is only one sealing pair, good manufacturing process, and the seat and valve disc are also easy to repair and replace. Due to the limitation of the shape inside the body cavity, the flow resistance of the medium is larger and the pressure loss is serious.

 

 

1, according to the sealing surface material is divided into:

Soft seal stop valve, hard seal stop valve

2, according to the structure of the valve disc is divided into:

Disc balance type stop valve, disc non-balance type stop valve.

3, according to the flow path form is divided into:

Straight flow stop valve, straight through stop valve, Angle stop valve, three way stop valve, etc.

4, according to the structure of the opening and closing parts:

Needle globe valve, plunger globe valve, bellows globe valve, etc.

5, according to the type of sealing can be divided into:

Plane seal stop valve, cone seal stop valve, guided seal stop valve, spherical seal stop valve, etc.

6, according to the position of the trapezoidal thread of the valve stem can be divided into:

Upper thread stem stop valve, lower thread stem stop valve.

7, according to the use of mining is divided into:

Low temperature stop valve, high temperature and high pressure power station stop valve, oxygen line stop valve, liquefied petroleum gas stop valve, hydrocracking device stop valve, insulation jacket stop valve, etc.

8, according to the combination with other valves to form a multi-functional globe valve, such as throttling globe valve, filter globe valve, etc.
