in the present embodiment, as shown in fig. 3 and 4, the mounting plate 71, the valve plate 72, the abutting assembly 8 and the stretching assembly, which are bilaterally symmetrical to the inside of the left lateral core tube 43, are also provided inside the right lateral core tube 43 on the basis of the first embodiment. When the valve body 5 is lifted or lowered, the components in the left and right lateral core tubes 43 are also symmetrically moved in opposite directions. When the valve core 5 descends to close the left side and the right side of the vertical core pipe, the transverse core pipe 43 on the left side and the right side can close the outer end parts of the left side and the right side, so that the flow of liquid in the flow channel on the lower end part of the vertical core pipe 42 can be more effectively prevented, and the sealing performance of the invention is further improved.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
