Description

Technical Field

[0001] The utility model relates to a high-efficiency sealed bellows stop valve, in particular to a high-efficiency sealed bellows stop valve. Background Art

[0002] High-efficiency sealed bellows stop valve is a valve that uses a unique bellows structure to achieve high-efficiency sealing. When the valve is closed, the bellows is deformed by pressure and fits tightly to the sealing component to ensure that the fluid does not leak out. When it is opened, the bellows returns to its original state and the fluid can flow smoothly. High-efficiency sealed bellows stop valve completely eliminates the possibility of steam leakage from the valve stem. The valve opening and closing operation is very flexible, and it does not require frequent maintenance and replacement of packing. The service life is more than 5 years.

[0003] When in use, the existing bellows stop valve needs to be connected to a high-density pipe. The high-density pipe is generally heavy and large, and it is very difficult to connect it during installation. The position needs to be constantly adjusted to align the fixed port on the pipe with the fixed port of the bellows stop valve. Constant adjustment and movement will cause wear to the pipe, thereby affecting the service life of the pipe. In addition, the threaded rod and the control valve of the adjusting bellows are exposed to the outside, which is easy to be entered by sand and other debris, thereby blocking the rotation gap between the threaded rod and the control valve, making the control valve unable to rotate, affecting the use of the bellows stop valve.
