1. The connection structure is simple, only need to tighten with thread shorting, manufacturing and maintenance is also more convenient.

2. It has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

3. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the function of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.

4. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.

5. It is widely used in oil and water steam pipelines such as petrochemical industry and thermal power plants to connect or cut off the intermediate quality of pipelines. The sealing surface of the opening and closing device has compact structure and reasonable design.

6. Fast and easy installation, strong steel. Both ends of the valve and the pipe are connected and sealed. For low pressure conditions, the sealing pipe thread connection is adopted. For high pressure conditions, the spherical active contact is combined with 0 type rubber sealing ring, especially for the occasions where the center requirements of both ends of the pipeline are not high.
