Description
Technical field
The utility model relates to a kind of valve, especially a kind of new-type gate valve.
Background technique
Gate valve is an opening and closing element spool, and the direction of motion of spool is vertical with flow direction, and traditionally gate valve is due to transport
The reason of fluid media (medium), will cause gate valve pivot region there is a situation where getting rusty, to cause artificially to be difficult to the case where opening hair
It is raw, sometimes, need to carry out using tool to agitate and can open reluctantly, when emergency occurs, the small and weak old man of body,
Child and women are difficult to open the valve of help, and such case is quite dangerous, can not in time, quickly open and get rusty
The valve of state will cause property loss and will cause the problem of human life can not ensure safely.
Utility model content
The utility model will solve the disadvantage that the above-mentioned prior art, provide it is a kind of can easily, facilitate the new-type of opening and closing
Gate valve, meeting in case of emergency being capable of quick, easily Open valve demand.
The utility model solves the technical solution of its technical problem use: this various new-type gate valve, including valve body, on valve body
It is provided with runner, the spool for opening and closing runner is longitudinally plugged on valve body, the top of spool is fixed with mast, and top end of the valve body is fixed
There is pedestal, pedestal is equipped with the driving mechanism that mast can be driven to move up and down;Driving mechanism includes the cavity opened on the base, chamber
It being equipped in vivo and is fixed on the transverse slat on mast top, the arranged on left and right sides of mast is designed with the first threaded rod at cavity, and two the
The top and bottom end of one threaded rod are all fixed with the round bar with the coaxial arrangement of the first threaded rod, and the cross section of bottom end round bar is less than the
