Description
Technical field
This utility model is related to a kind of valve, more particularly to a kind of gate valve.
Background technology
Valve is in fluid system, for controlling the device of the direction of fluid, pressure, flow, is to make pipe arrangement and equipment
Interior medium (liquid, gas, powder) flows or stops and can control the device of its flow.Valve has many types, such as gate valve,
Choke valve, ball valve, butterfly valve, diaphragm valve, plunger valve, plug valve etc..Gate valve is an opening and closing element flashboard, the direction of motion of flashboard with
Flow direction is perpendicular, and gate valve can only make standard-sized sheet and fully closed.Gate valve flow resistance is little, is not likely to produce water hammer, simple structure,
Both sides are symmetrical, and the scope of application is very wide.But, in gate valve opening-closing process, sealing part abrasion is serious, and most gate valves are all because sealing member is damaged
Bad, leakage, finally cannot just be continuing with；This serious curtailment service life of gate valve, limits the application of gate valve.
Content of the invention
This utility model provides a kind of gate valve for solving above-mentioned technical problem.
Technical solution adopted in the utility model is：A kind of gate valve, including valve body, valve gap, handwheel, valve rod and two shoe brakes
Plate, also includes middle frame of the section in up big and down small H-shaped；The valve rod bottom is connected on the middle frame horizontal component；Two pieces
The flashboard is respectively slidably connected to the middle frame both sides；The flashboard is in tetragon, the tactile side with the middle bridge joint
Fit with the middle frame；Limiting plate is provided with the flashboard relative position in the valve body.Handwheel is rotated, valve rod declines, and drives
Middle frame and flashboard decline；When flashboard lower surface contact limiting plate upper surface after, flashboard cannot decline together with middle frame, flashboard with
There is relative slip in middle frame；As middle frame is up big and down small, therefore as middle frame is moved down, flashboard is pushed to both sides, until being against valve
On seat, the closing of gate valve is realized；In middle frame is relative to flashboard folding process, as flashboard is fitted with middle bridge joint contacting surface, protect
Card ram movement is translation, does not rotate.In this utility model gate valve opening-closing process, flashboard is alleviated close with valve seat without friction
The abrasion of sealing, extends gate valve service life.
If the contact surface of limit flashboard and limiting plate is plane, flashboard when spacing plate surface is moved to valve seat resistance compared with
Greatly, limiting plate pressure is also larger so that limiting plate is fragile, therefore preferably, the flashboard and the limiting plate
Contact surface is inclined-plane, near valve body center one end higher than near one end of valve seat.
Preferably, the middle frame two side is provided with spherical sliding block near lower edge, the flashboard relevant position is provided with
Groove of the section in major arc shape, the groove closed at both ends.Groove provides space for spherical sliding block, and groove upper end closed is
Flashboard can be driven after spherical sliding block moves to groove upper end in gate opening to rise；Groove lower end closed is in order to lock
Plate level position do maximum spacing, in order to avoid with valve seat apart from too small and damage sealing member by pressure.
Preferably, the spherical sliding block totally 8, is symmetrically distributed in the middle frame both sides, 4 spherical cunnings per side
Block is in matrix distribution.It is that it is to increase stress point that horizontal direction sets two in order to prevent flashboard from overturning that vertical direction sets two.
Preferably, the groove lower end is provided with rubber blanket.So that flashboard is in level maximum spacing place slightly surplus, to control
Sealing member processed presses degree.
This utility model has the advantages and positive effects of：As this utility model is using as above technical scheme, rotate
Handwheel, valve rod decline, and band disorder of internal organs frame and flashboard decline；After flashboard lower surface contacts limiting plate upper surface, flashboard cannot be with
Middle frame declines together, and flashboard is relative with the generation of middle frame to slide；Due to middle frame up big and down small, therefore as middle frame is moved down, flashboard quilt
Push both sides to, until being against on valve seat, realize the closing of gate valve；In middle frame is relative to flashboard folding process, due to flashboard with
Middle bridge joint contacting surface fits, it is ensured that ram movement is translation, does not rotate.In this utility model gate valve opening-closing process flashboard with
Valve seat alleviates the abrasion of sealing member without friction, extends gate valve service life.
Except this utility model described above solve technical problem, constitute technical scheme technical characteristic and by
Outside the advantage brought by the technical characteristic of these technical schemes, other technologies problem that this utility model can be solved, technology
The advantage brought by the other technical characteristics included in scheme and these technical characteristics, makees into one hereinafter in conjunction with accompanying drawing
Step detailed description.

Specific embodiment
For content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and is coordinated
Accompanying drawing describes in detail as follows：
As shown in figure 1, the present embodiment is a kind of gate valve, including valve body 1, valve gap 2, handwheel 3, valve rod 4 and two shoe brake plates 5,
Also include middle frame 6 of the section in up big and down small H-shaped；4 bottom of the valve rod is connected on 6 horizontal component of middle frame；Two pieces
The flashboard 5 is respectively slidably connected to 6 both sides of middle frame；The flashboard 5 is contacted with the middle frame 6 in tetragon
Fit with the middle frame 6 side；Limiting plate 7 is provided with 5 relative position of the flashboard in the valve body 1.The flashboard 5 with described
The contact surface of limiting plate 7 is inclined-plane, near 1 center one end of the valve body higher than near one end of valve seat.
As shown in Figures 2 and 3,6 two side of middle frame is provided with spherical sliding block 8 near lower edge, and the flashboard 5 is corresponding
Position is provided with groove 9 of the section in major arc shape, is that spherical sliding block 8 provides space；9 closed at both ends of the groove.The ball
Shape slide block 8 totally 8, is symmetrically distributed in 6 both sides of middle frame, and 4 spherical sliding blocks 8 per side are in matrix distribution.Described recessed
9 lower end of groove is provided with rubber blanket 10.
The course of work of the present utility model is：Handwheel is rotated, valve rod declines, band disorder of internal organs frame and flashboard decline；When under flashboard
After surface contact limiting plate upper surface, flashboard cannot decline together with middle frame, and flashboard is relative with the generation of middle frame to slide；Due in
Frame is up big and down small, and therefore as middle frame is moved down, flashboard is pushed to both sides, until being against on valve seat, realizes the closing of gate valve；Gate valve
Open and close process will not be described here conversely, principle is similar.
Above embodiment of the present utility model is described in detail, but the content has been only of the present utility model preferable
Embodiment, it is impossible to be considered as limiting practical range of the present utility model.All according to this utility model application range made equal
Deng change and improvement etc., still all should belong within patent covering scope of the present utility model.
