Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

The embodiment of the utility model provides a do:

referring to fig. 1 to 4, a novel lifting stop valve includes a valve body 1, the valve body 1 is made of plastic, the valve body 1 has a first connection port 11, a second connection port 12 and a medium flow channel 13 connecting the first connection port 11 and the second connection port 12, a third connection port 14 communicated with the medium flow channel 13 is arranged on the valve body 1, specifically, the third connection port 14 is distributed between the first connection port 11 and the second connection port 12, a central axis of the third connection port 14 is perpendicular to a central axis of the medium flow channel 13, a metal connection ring 2 is embedded in the third connection port 14, an internal thread 3 is arranged on the metal connection ring 2, abrasion of the internal thread 3 is prevented for multiple times, durability is improved, a valve seat 4 is connected to the third connection port 14 through a thread, a valve rod 5 is arranged on the valve seat 4, a plug 6 is arranged at a lower end of the valve rod 5, the plug 6 is vertically moved by rotating the valve rod 5, opening/closing of the medium flow channel 13 is realized, and a twist handle 7 is arranged at an upper end of the valve rod 5, so that rotation is facilitated and convenience in use is improved.

Referring to fig. 5, in this embodiment, the valve rod 5 includes a first rod 51 and a second rod 52, the first rod 51 is rotatably disposed on the upper portion of the valve seat 4, the second rod 52 is slidably disposed on the lower portion of the valve seat 4, the first rod 51 is in threaded connection with the second rod 52, the second rod 52 in threaded connection with the first rod 51 slides in the axial direction by rotating the first rod 51, specifically, the first rod 51 has a first external thread 53 at the lower end thereof, the second rod 52 has a connection hole 54 at the upper end thereof, a first internal thread 55 matching with the first external thread 53 is disposed in the connection hole 54, and the second rod 52 is in a prism structure, preferably a hexagonal prism structure, and the rotation of the second rod 52 is limited by the arrangement of the prism structure, and since the first external thread 53 on the first rod 51 is connected with the first internal thread 55 in the connection hole 54 of the second rod 52, the second rod 52 is driven to move in the axial direction when the first rod 51 is rotated, and further drive the plug 6 to move up and down, thereby opening/closing the medium channel 13 is realized.
