Description
Technical field
It the utility model is related to plug valve, and in particular to a kind of turbine type cutting ferrule soft sealing plug valve.
Background technology
Soft sealing plug valve is used mainly for opening and closing pipeline and equipment medium, and soft sealing plug valve is usually used in corroding
Property, severe toxicity and height endanger the severe rugged environments such as medium, the strict occasion for prohibiting leakage, although existing valve is with good sealing
Property, but after long-time use, the gap between valve element and valve will constantly increase, so that liquid overflows from gap
Go out, it is impossible to meet people for the demand of the valve required compared with high leakproofness.
The content of the invention
In order to solve the above problems, the utility model provides a kind of turbine type cutting ferrule soft sealing plug valve.
The technical solution of the utility model is：A kind of turbine type cutting ferrule soft sealing plug valve, including valve body, cock stem, card
Set, valve rod, O-ring seal, wedge, pad, gland, bonnet, valve stem connection, turbine box, cock is provided with valve body
Bar, cutting ferrule are set on cock stem, and the outer face of cutting ferrule is in contact with the medial surface of valve body, under the upper end and valve rod of cock stem
The junction of end connection, cock stem and valve rod is provided with O-ring seal, and O-ring seal is set on valve rod, O-ring seal
Periphery wall is in contact with wedge, and wedge is arranged between cock stem and pad, and end is provided between pad and gland
Spherical bearing, bonnet are fixed on the upper surface of gland, and the upper end of valve rod is provided with valve stem connection, valve stem connection and turbine box
Connection.
Further, the outside wall surface of the wedge and the medial surface of pad are brought into close contact, and the bottom face of wedge is tight
It is close to be fitted on the upper surface of cock stem.
Further, the cutting ferrule is made up of PTFE.
Further, the cock stem is molded with valve-stem integrated.
Further, the valve stem connection is connected with turbine box by flat key.
The beneficial effects of the utility model are：The utility model uses cutting ferrule soft seal, improves sealing property, effectively keeps away
Exempt from medium leakage.
