Advantages and disadvantages of the shut-off valve and installation precautions

The globe valve has the following advantages:
1. The stop valve has a simple structure and is convenient to manufacture and maintain.
2. The working stroke of the stop valve is small, and the opening and closing time is short.
3. The sealing valve has good sealing performance, small friction between sealing surfaces and long service life.
The disadvantages of the globe valve are as follows:
1. The fluid resistance of the shut-off valve is large, and the force required for opening and closing is large.
2. The shut-off valve is not suitable for media with particles, high viscosity and easy coking.
3. The shut-off valve has poor regulation performance.
The type of the shut-off valve is divided into an external thread type shut - off valve and an internal thread type shut - off valve according to the position of the stem thread. According to the flow direction of the medium, there are straight-through stop valves , DC-type shut - off valves and angle-type shut-off valves. The shut-off valve is divided into seals, with a packing seal shut-off valve and a bellows seal shut-off valve.
The following items should be noted for the installation and maintenance of the shut-off valve:
1. The handwheel and handle operated shut-off valve can be installed at any position of the pipeline.
2. Handwheels, handles and aerodynamic mechanisms are not allowed to be used for lifting.
3. The flow direction of the medium should be consistent with the direction of the arrow shown in the valve body.
