And O-shaped sealing rings for adjusting the sealing performance of the valve seat and the valve seat sealing ring are also arranged between the valve seat and the valve body and between the valve seat and the hot melting socket joint.
The valve seat is provided with a mounting groove, and the valve seat sealing ring is arranged in the mounting groove.
The valve seat is also provided with a groove, and the O-shaped sealing ring is arranged in the groove.
The surface of the sphere is polished.
The utility model has the advantages that: the utility model provides a socket joint formula plastic ball valve, including the valve body, the outside of valve body is equipped with hot melt socket joint, is equipped with spheroid and disk seat in the valve body, and the disk seat setting is equipped with the disk seat sealing washer between spheroid and hot melt socket joint on the disk seat, sealed cooperation between disk seat sealing washer and spheroid, valve body and disk seat between pass through threaded connection, the upper end of valve body still is equipped with the lock nut who is used for fixed valve body and hot melt socket joint, threaded connection between valve body and lock nut, screw thread direction of rotation between valve body and disk seat and valve body and lock nut between screw thread direction of rotation opposite, these two kinds of screw thread reverse structure designs, when lock nut and valve body erection joint, can not lead to the disk seat to be driven slack, produce sealing performance and reduce, and only can only revolve tight more.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The valve comprises a valve body 1, a hot-melting socket joint 2, a ball 3, a valve seat 4, a locking nut 5, a valve seat sealing ring 41 and an O-shaped sealing ring 42.
Detailed Description
Now combine fig. 1 to explain further the utility model discloses a socket joint formula plastic ball valve, including valve body 1, the outside of valve body 1 be equipped with hot melt socket joint 2, valve body 1 in be equipped with spheroid 3 and disk seat 4, disk seat 4 set up between spheroid 3 and hot melt socket joint 2, disk seat 4 on be equipped with disk seat sealing 41, disk seat sealing 41 and spheroid 3 between sealed cooperation, valve body 1 and disk seat 4 between pass through threaded connection, the upper end of valve body 1 still be equipped with the lock nut 5 who is used for fixed valve body 1 and hot melt socket joint 2, valve body 1 and lock nut 5 between threaded connection, the screw thread direction of rotation between valve body 1 and disk seat 4 opposite with valve body 1 and lock nut 5 between the screw thread direction of rotation. The valve body 1 and the valve seat 4 are provided with right-handed threads, and the valve body 1 and the locking nut 5 are provided with left-handed threads. The two reverse structural designs of the thread can not lead to the valve seat being driven to be loosened and the sealing performance to be reduced when the locking nut is installed and connected with the valve body, and only the locking nut is screwed more and more tightly.
And O-shaped sealing rings 42 for adjusting the sealing performance of the valve seat 4 and the valve seat sealing ring 41 are also arranged between the valve seat 4 and the valve body 1 and between the valve seat 4 and the hot melting socket joint 2. Set up EPDM material O type circle behind the disk seat can be better the sealing performance of regulating valve spheroid and disk seat sealing washer. Especially in corrosive media with particles, the ball and the valve seat sealing ring may be abraded for a period of time, so that the optimal sealing effect is achieved through adjustment of the O-ring behind the valve seat.
The valve seat 4 is provided with a mounting groove, and the valve seat sealing ring 41 is arranged in the mounting groove.
The valve seat 4 is further provided with a groove, and the O-shaped sealing ring 42 is arranged in the groove.
The surface of the ball body 3 is polished, so that the friction force between the ball body and the valve seat seal is reduced, the surface abrasion of the ball body is reduced, and the operation torque is reduced.
