There are many kinds of structural forms and specifications of the globe valve, and new products and new structures will appear. So, what kind of structure does the existing shut-off valve have? In addition, what should you pay attention to when installing and maintaining?
The structural form of the globe valve:
The structure of the shut-off valve body is straight-through, direct-flow and right-angle. Straight-through is the most common structure, but its fluid resistance is greatest. DC fluid resistance is small, and it is mostly used for fluids containing solid particles or high viscosity. The right angle valve body is mostly forged, suitable for small through, high pressure shut-off valves.
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.
For those who are constantly in contact with the shut-off valve, the protection of the shut-off valve is more conducive to its service life.
