The inlet and outlet is connected, and the valve rod lower end is equipped with valve plug, and valve plug is extend into the valve chamber of valve body, and the valve plug is equipped with
Conical chock plug, the side of valve plug are set as the conical surface, and the valve chamber is corresponding to the contact surface of valve plug to be set as the conical surface, and valve plug connects with valve chamber
Touching, which is formed, to be tightly connected；The upper end of the valve plug is cylindrical plugs neck, fills in and is arranged with sealing ring on neck.
As the preferred technical solution of the present invention, the exit of the valve body is equipped with cap nut, is equipped in cap nut
Connector, the tail portion of connector are equipped with pipeline and connect locking strap.
As the preferred technical solution of the present invention, the outlet of the valve body is set as cone shaped opening, and the connector is set as
Taper joint, taper joint are mutually adapted with valve outlet.
As the preferred technical solution of the present invention, it is flexibly connected between the valve rod and valve deck by screw thread formation, valve rod
It can move up and down with respect to valve deck.
As the preferred technical solution of the present invention, the valve deck upper end is equipped with centre bore, and bushing, lining are equipped in the centre bore
It puts on and is equipped with clamp nut；Valve body import and valve outlet coaxial line.
As the preferred technical solution of the present invention, the upper surface of described valve plug plug neck is sealing station terrace, the sealing ring with
Sealing station terrace pastes connection.
The beneficial effects of the present invention are: compared with the existing technology, valve plug of the present invention is using conical chock plug and sealing ring, no
Easily leakage.Bushing is provided in the centre bore of valve deck, valve plug is adapted to the centre bore of valve chamber and forms good sealed connection.This
It is invention intensity height, good seal, compact-sized and long service life, easy for operation.
