Abstract
The utility model discloses a double inclined plane parallel wedge disc gate valve comprising a hand wheel 1, a valve cover 2, a valve seat 3 and a valve rod 4, wherein the bottom end of the valve rod 4 is connected with a wedge disc 5, the wedge disc 5 takes the shape of a cone frustum and is externally sheathed with a cylindrical sealing surface 11, an inner contact surface of the sealing surface 11 is matched with an external contact surface of the wedge disc 5, the sealing surface 11 is movably connected with an upper cover 10 through a screw 9, the bottom end of the sealing surface 11 is connected with a bottom plate 7, the upper and lower parts of the interior of the sealing surface 11 are respectively provided with an upper positioning pin 8 and a lower positioning pin 10, and the wedge disc 5 respectively penetrates through the upper positioning pin 8 and the lower positioning pin 10. The double inclined plane parallel wedge disc gate valve has the beneficial effects that in the starting and closing processes of the valve, the abrasion between the sealing surfaces of the valve is small, the sealing performance is reliable and the service life of products is long.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of parallel flashboard gate valve.
Background technique
Problems such as the flashboard of tradition double-flashboard gate valve is parallel, and in the opening-closing process of gate valve, the sealing surface of flashboard and the sealing surface of valve seat have wearing and tearing, cause sealing surface wear fast, and the working life of valve is short.
Summary of the invention
At the existing shortcoming of existing parallel flashboard gate valve, the utility model provides a kind of novel parallel flashboard gate valve.
Technical solution adopted in the utility model is:
The parallel flashboard gate valve of double inclined plane lock, it comprises handwheel 1, valve gap 2, valve seat 3, valve rod 4, the bottom of valve rod 4 is connected with flashboard 5, flashboard 5 is round table-like profile, be with cylindric sealing surface 11 outside the flashboard 5, the interior surface of contact of its sealing surface 11 matches with the outer contacting face of flashboard 5, and sealing surface 11 flexibly connects by screw 9 and loam cake 10, and the bottom of sealing surface 11 is connected with base plate 7, sealing surface 11 inside are respectively arranged with locating stud 8 and following locating stud 10 up and down, and flashboard 5 passes locating stud 8 and following locating stud 10 respectively;
Described locating stud 10 down is provided with spring 6.
The beneficial effects of the utility model: wearing and tearing are little between the valve sealing face in the opening-closing process of valve, and sealability is reliable, long product lifecycle.

Embodiment
See also its implementation process of description of drawings:
The parallel flashboard gate valve of double inclined plane, it comprises handwheel 1, valve gap 2, valve seat 3, valve rod 4, the bottom of valve rod 4 is connected with flashboard 5, flashboard 5 is round table-like profile, be with cylindric sealing surface 11 outside the flashboard 5, the interior surface of contact of its sealing surface 11 matches with the outer contacting face of flashboard 5, and sealing surface 11 flexibly connects by screw 9 and loam cake 10, and the bottom of sealing surface 11 is connected with base plate 7, sealing surface 11 inside are respectively arranged with locating stud 8 and following locating stud 10 up and down, and flashboard 5 passes locating stud 8 and following locating stud 10 respectively; Described locating stud 10 down is provided with spring 6.During Open valve: rotate handwheel 1, handwheel 1 drives valve rod 4 and rises, and the sealing surface 11 that is attached thereto simultaneously, flashboard 55 etc. rise in the cavity below the valve gap 2 together, and last locating stud 8 valve openings rising plays the role of positioning.During throttle down: counter-rotation handwheel 1 moves downward valve rod 4 and flashboard 5, spring 6 together.When sealing surface 11, flashboard 55 etc. moved to the bottom together, when can not descend, valve rod 4 drove flashboard 5, sealing surface 11 continues to move downward again.When just flashboard 5 is put into, the sealing surface 11 on both sides is strutted automatically, this moment, base plate 7 played the positioning action of flashboard 5 on earth the time.The effect of screw 9 fixed valve flashboards 5, screw 9 can about movable.Flashboard 5 is withstood and can not continue to move downward again.The sealing surface 11 on both sides seals with the pipeline opening of valve seat 3, just reaches the purpose of throttle down.Following locating stud 10 is provided with spring 6, is exactly flashboard 5 when moving downward, and a buffer function is played in the back on earth.The beneficial effects of the utility model: wearing and tearing are little between the valve sealing face in the opening-closing process of valve, and sealability is reliable, long product lifecycle.
Those skilled in the art's simple replacement and replacing all are within the protection domain of this patent in related domain.
