Its structure is as follows:
1. Valve body:
The valve body of the plug valve is generally cylindrical, and is generally divided into two types: straight-through type and angle type. The inlet and outlet of the straight-through plug valve are on the same axis, while the inlet and outlet of the angle plug valve are at a 90-degree angle.
2. Valve:
The valve of the plug valve is conical or spherical and can be rotated 90 degrees to achieve on-off control.
3. Gasket:
There is a sealing gasket between the valve and the valve body to ensure the sealing performance of the valve.
4. Valve stem:
The valve stem connects the valve and the handwheel. The valve can be opened or closed by rotating the handwheel.
5. Hand wheel:
The handwheel is the operating component of the plug valve, and the valve can be opened or closed by rotating the handwheel.
The above is the basic structure of the plug valve. Plug valves can usually be used in high-pressure and high-temperature environments and have a long service life.
