Description
Technical field
The utility model is related to valve field, and in particular to a kind of gate valve.
Background technology
Gate valve is an opening and closing element flashboard, and the direction of motion of flashboard is perpendicular with flow direction, when gate valve is closed, sealing surface
Seal by pressure medium, the sealing surface of flashboard is pressed to into the valve seat of opposite side to ensure the sealing of sealing surface, here it is from
Sealing.Flashboard will be pressed to valve seat by most of gate valve by force using during forced seal, i.e. valve closing by external force, with
Ensure the sealing of sealing surface, when opening and closing, valve element and sealing surface of seat are contacted all the time and phase mutual friction gate valve, thus
Sealing surface easily weares and teares, and particularly when valve is in close closed mode, pressure reduction is very big before and after valve element, and sealing surface wear is just more
Plus it is serious, but sealing surface wear easily causes leak or phenomenon of getting rusty, and keeps in repair relatively difficult, so as to shorten the use longevity of valve
Life.
The content of the invention
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of gate valve, its simple structure,
Switch is light and handy, sealed reliable, be difficult to get rusty, long service life.
In order to solve the problems of background technology, the utility model is to employ the following technical solutions：A kind of gate valve, it
Including valve body；Include valve seat, flashboard, valve rod, valve gap on described valve body；Described valve gap is arranged on valve body；Described valve
