Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the following description of the preferred embodiments of the present invention is provided in conjunction with the specific examples, but it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent requirements of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The invention will be further described with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 1 to 2, the mechanical locking valve structure according to the present embodiment includes a pipe body 11 connected in series with a ball valve 10, where the ball valve 10 has a valve handle 12 for controlling the pipe body 11 to open and close, and the valve handle 12 is provided with a rotation limiting portion 13 that rotates horizontally and circumferentially along with the valve handle 12;

still include locking mechanical system 20, locking mechanical system 20 includes locking frame 21, is equipped with on the locking frame 21 to be located with the epaxial last sliding sleeve 22 of perpendicular and lower sliding sleeve 23, it blocks the rotation limiting portion 13 and makes pivoted gag lever post 24 to go up sliding sleeve 22 and the 23 sliding connection in lower sliding sleeve, it is equipped with the driven ring 25 of rigid coupling on gag lever post 24 to go up sliding sleeve 22 and lower sliding sleeve 23 within a definite time, still the cover is equipped with reset spring 26 of sliding sleeve 23 under one end butt driven ring 25, the other end butt on the gag lever post 24.

In this embodiment, firstly, the ball valve 10 is in a non-conducting state, the pipeline body 11 cannot realize gas-liquid conduction, and at this time, the rotation limiting part 13 abuts against the top end of the extended limiting rod 24, so that the valve handle 12 cannot rotate horizontally and circumferentially; when the pipeline main body 11 needs to be conducted, the limiting rod 24 is moved downwards, the top end of the limiting rod is made to descend to the position where the rotation limiting part 13 is not blocked any more, and then the valve handle 12 is manually rotated, so that the ball valve 10 can be opened, and the pipeline main body 11 is conducted.

If the reset is needed, the limiting rod 24 still needs to be pressed down, the valve handle 12 is reset firstly, and after the limiting rod 24 is reset again under the action of the reset spring 26, the rotation of the valve handle 12 is limited, and the mechanical locking of the ball valve 10 is realized.
