Description
Technical field
A kind of valve is the utility model is related to, more particularly to a kind of gate valve.
Background technology
Valve is the control unit in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the function such as overflow pressure relief.Gate valve is widely used one kind in various types of valve.Gate valve is mainly by valve body, bonnet, hand
Wheel, valve rod, flashboard, valve seat are formed, by the lifting of flashboard come the keying of control gate valve.Gate valve flow resistance is small, is not likely to produce
Water hammer, simple in construction, both sides are symmetrical, and the scope of application is very wide.Existing gate valve flashboard and valve seat in opening-closing process produce
Friction sealing surface is caused to wear, decline Gate-valve sealing, shorten the service life of gate valve.
Utility model content
Based on above mentioned problem, the utility model purpose is to provide a kind of gate valve, and it is right in opening-closing process to solve gate valve
The problem of sealing surface wear is big, improve the service life of gate valve.
For problem above, there is provided following technical scheme：A kind of gate valve, including valve body, valve rod, medium runner, valve plate
And the valve seat coordinated with valve plate sealing, the valve plate include the left valve plate coordinated with the sealing of valve seat both ends of the surface and right valve plate, institute
The bottom for stating valve rod is provided with the axle sleeve being slidably matched with it, and at least two companies are respectively provided between the axle sleeve and left and right valve plate
Fitting, the both ends of the connector are movably hinged with axle sleeve and left and right valve plate respectively, the connector relative to axle sleeve to
Outside, down-set, at least two connectors are set in the plane in parallel of the length direction along valve rod, and the gate valve also includes valve
Supporting surface on body immediately below the valve plate, when the lower surface of left and right valve plate moves to supporting surface, the left and right valve plate to
Valve seat direction is mobile and coordinates with valve base sealing, and the both ends on the valve rod positioned at axle sleeve are respectively equipped with convex platform and lower convex platform,
The distance between described upper and lower boss is more than the length of axle sleeve, and compression spring is provided between the axle sleeve and convex platform.
The utility model is further arranged to, and the lower convex platform is detachably connected with valve rod.
The utility model is further arranged to, and the valve seat is provided with O-ring seal.
The utility model is further arranged to, the valve seat or left and right valve plate built-up welding STL.
The beneficial effects of the utility model, compared with existing gate valve, gate valve of the present utility model by with positioned at valve rod
On the connector that is movably hinged of axle sleeve and left and right valve plate, when valve rod moves upwards, axle sleeve together rises with valve rod, from
And drive left and right valve plate to rise and shrink, prevent that the friction of valve plate and valve seat from causing the destruction of sealing surface, when valve rod moves downward
When, left and right valve plate is stopped by the supporting surface on valve body, it is impossible to continues to move downward, but valve rod is passing through handwheel energy band moving axis
Set continues to move downward, and the lengthwise movement of valve rod is changed into the transverse movement of left and right valve plate by connector by valve rod, make it is left,
Right valve plate moves to valve seat direction and forms tight seal with valve seat.

Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
A kind of gate valve as shown in Figure 1, including valve body 1, valve rod 2, medium runner 3, valve plate and being sealed with valve plate coordinate
Valve seat 4, the valve seat 4 is provided with O-ring seal 41, and the valve plate includes the left valve plate coordinated with the sealing of the both ends of the surface of valve seat 4
5 and right valve plate 6, the bottom of the valve rod 2 is provided with the axle sleeve 21 being slidably matched with it, the axle sleeve 21 and left and right valve plate（5、
6）Between be respectively provided with least two connectors 7, the both ends of the connector 7 respectively with axle sleeve 21 and left and right valve plate（5/6）It is living
Dynamic be hinged, the connector 7 is outside, down-set relative to axle sleeve 21, and at least two connectors 7 are in the length side along valve rod 2
To plane in parallel set, the gate valve also includes the supporting surface 11 on valve body 1 immediately below the valve plate, when left and right valve plate
（5、6）Lower surface when moving to supporting surface 11, the left and right valve plate（5、6）Seal to the movement of the direction of valve seat 4 and with valve seat 4
Coordinate, the both ends on the valve rod 2 positioned at axle sleeve 21 are respectively equipped with convex platform 22 and lower convex platform 23, the upper and lower boss（22、
23）The distance between be more than axle sleeve 21 length, compression spring 24 is provided between the axle sleeve 21 and convex platform 22, it is convex under described
Platform 23 is detachably connected with valve rod 2, the valve seat 4 or left and right valve plate（5、6）Built-up welding STL,.
Gate valve of the present utility model by with the axle sleeve 21 on valve rod 2 and left and right valve plate（5、6）It is movably hinged
