To limiting slot and the limit flat key being mounted in radial direction limiting slot composition.
Preferably, limit flat key is inlaid in the radial limiting slot of right flashboard, and thickness, which is less than in right flashboard, radially to be limited
The depth of slot, and be greater than the depth of radial limiting slot in left flashboard, right flashboard radial direction limiting slot slot bottom and limit flat key it
Between spring is installed.
The utility model has the advantages that left flashboard and right flashboard are connected with each other using guide tracked T-type button, during the shutdown process
Left flashboard and right flashboard can generate small relative displacement under valve rod thrust on valve rod centerline direction, make left lock
Plate and right flashboard paste tight sealing engagement with import valve seat and outlet valve seat respectively, eliminate left flashboard and right flashboard and import valve seat and
Outlet valve seat sealing surface processing and installation error influences flashboard and valve base sealing matching property.Small with small product size, at low cost,
The features such as installation space is small, good seal performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Electronic double buckle type high-temperature and high-pressure wearable gate valves as shown in Figure 1, including valve body 1, valve seat 2, flashboard 3, valve rod 4,
Valve deck 5, bracket 6, transmission device 8, valve seat 2 are made of import valve seat and outlet valve seat, are separately mounted to valve body 1 and are imported and exported channel
Interior, the sealing surface of two valve seats constitutes v-shaped structure, and flashboard 3 forms double disc structure, two ram seals using left flashboard and right flashboard
Face, which is constituted, has resistance to height using self sealing structure between valve deck 5 and valve body 1 with two sealing surface of seats mutually matched v-shaped structure
Performance is pressed, stuffing seal is set between 4 middle part periphery of valve rod and valve deck 5,4 upper end of valve rod passes through valve stem nut 7 and passes
Dynamic device 8 connects, and transmission device 8 uses electric device, and 3 sealing surface of flashboard and 2 sealing surface of valve seat use built-up welding stellite,
With high temperature resistant, wear-resisting property；It is characterized in that left flashboard and right flashboard are connected with each other using guide tracked T-type button, the guide tracked T
Type buckle by the T-type in the right plane of left flashboard perpendicular to 4 centerline direction of valve rod buckle and right flashboard left plane in perpendicular in valve rod 4
The T-type guide rail in heart line direction forms；There is the T-type window that cooperation is mutually embedded in T-type guide rail, T-type guide rail is embedded on the inside of T-type button
In the T-type window, left flashboard and right flashboard are mutually snapped together, it is left using the installation of flashboard frame to solve the prior art
The shortcomings that right flashboard, increase small product size and cost, T-type button is matched on 4 centerline direction of valve rod using gap with T-type guide rail
It closes, makes left flashboard and right flashboard that can eliminate automatically 3 He of flashboard in closing process with micro movement on 4 centerline direction of valve rod
2 processing and installation error of valve seat causes the influence to sealing matching property；Radial limit is set between left flashboard and right flashboard
Device, the radial limiting device are perpendicular to the limiting device in 3 diametrical direction of flashboard of 4 center line of valve rod, prevent left lock
Plate is diametrically displaced with right flashboard.
The T-type button is elastic buckles, and epicoele 11 and cavity of resorption 10 are constituted between outside and left flashboard and right flashboard, for elasticity
Button provides the elastic deformation space along 4 centerline direction of valve rod.This, which is elastically snapped into 3 closing process of flashboard, makes left flashboard and You Zha
Small axially opposing displacement is generated between plate, the axially opposing displacement refers to the displacement in 4 centerline direction of valve rod, automatically
It adjusts V-arrangement between left flashboard and right gate sealing surface and import valve seat and outlet valve seat sealing surface and matches close angle, compensation or elimination lock
3 sealing surface of plate and 2 sealing surface of valve seat are because of mismatch error caused by mismachining tolerance and rigging error.
The radial limiting device is limited by the right plane of left flashboard and the radial of right flashboard left plane corresponding position setting
Slot and the limit flat key 12 being mounted in the radial direction limiting slot form.The radial direction limiting slot refers to flashboard 3 perpendicular in valve rod 3
The diametric limiting slot of heart line, limit flat key 12 are inlaid in the radial limiting slot between left flashboard and right flashboard, prevent
The two radial displacement.
Limit flat key 12 is inlaid in the radial limiting slot of right flashboard, and thickness is less than the depth of radial limiting slot in right flashboard
Degree, and it is greater than the depth of radial limiting slot in left flashboard, pacify between the slot bottom and limit flat key 12 of right flashboard radial direction limiting slot
Shock mount 9.When left flashboard is aligned with the radial limiting slot of right flashboard, limit flat key 12 is pushed into the radial direction of left flashboard by spring 9
In the radial limiting slot of limiting slot and right flashboard, prevents left flashboard from generating with right flashboard and be diametrically displaced.
4 lower end of valve rod and 3 upper end of flashboard use inverted T shaped connection, and the radial limiting device is by being inlaid in 4 periphery of valve rod
Radial limit sleeve composition between flashboard 3.The radial direction limit sleeve is by the nut press mounting that is threadedly engaged with valve rod 4 outside valve rod 4
Between disc and the radial limit hole of flashboard 3, left flashboard is prevented diametrically to be displaced with right flashboard.
