Description
Technical field
The invention belongs to valve field more particularly to a kind of wedging type flat gate valves.
Background technique
Wedging type flat gate valve is generally made of main gate-board and auxiliary gate-board, and inclined-plane or K are used between main gate-board and auxiliary gate-board
Shape inclined-plane cooperates, and main gate-board and auxiliary gate-board be mounted in flashboard frame, and when unlatching, main gate-board rises to be detached from auxiliary gate-board inclined-plane
Auxiliary gate-board is pulled to be promoted together again afterwards, when closing, auxiliary gate-board is strutted after in place by the wedging of main gate-board inclined-plane and seat compression seals
Cooperation, reduces the abrasion in opening-closing process between gate sealing surface and sealing surface of seat.Its major defect is, long-term in gate valve
Under closed state, mutual bonding force is easy to produce between main gate-board and the inclined-plane of auxiliary gate-board, unlatching moment is big, leads when valve rod pulls
When flashboard rises, the bonding force between main gate-board and auxiliary gate-board inclined-plane causes the two that cannot disengage in time, is easy to drive secondary
Flashboard is mobile simultaneously, produces gate sealing surface and sealing surface of seat and wears, influences product hermeticity energy and service life.
Summary of the invention
The present invention is directed to disadvantage of the existing technology, and it is small to provide a kind of unlatching moment, in valve opening, main gate-board with
Auxiliary gate-board can be disengaged reliably, and sealing performance is reliable, elastic wedging type flat gate valve with long service life.
Technical solution of the present invention includes valve body, valve seat, valve deck, valve rod, flashboard, and flashboard is by main gate-board and auxiliary gate-board group
At, between main gate-board and auxiliary gate-board using inclined-plane mutual cooperation contact, main gate-board upper end center is connect with valve rod lower end, in main switch
It is equipped with the limit plate being fixedly connected with auxiliary gate-board above plate, guide pile is set in body cavity bottom；Mainly main gate-board with
Elastic release unit is equipped between auxiliary gate-board, the elasticity release unit is used installs hook-type bullet between main gate-board and auxiliary gate-board
Spring, one end of the hook-type spring are pressed in the made hook groove in main gate-board inclined-plane side, and the other end passes through auxiliary gate-board, and by nut
It is fixedly mounted on the made installation inclined-plane in auxiliary gate-board sealing surface side.
Preferably, the hook-type spring one end in main gate-board hook groove is T-shaped structure, is pressed on the upside of T-shaped structure
Between the left side wall and slot bottom of main gate-board hook groove.
It preferably, is clearance fit between the two sidewalls of main gate-board hook groove and the T-shaped structure end of hook-type spring.
Preferably, hook-type spring is being uniformly arranged several perpendicular to valve rod centerline direction.
Compared with the prior art, the present invention has the advantages of between main gate-board and auxiliary gate-board setting be made of hook-type spring
Auxiliary gate-board is connected on main gate-board by elastic release unit by hook-type spring, when valve rod drives main gate-board to open, hook-type spring
Elastic force to upper left generated to main gate-board, and to auxiliary gate-board generate to the right to pressure, push main gate-board and secondary lock
Plate reliable separation reduces unlatching moment, and shrinks the axial width of main gate-board and auxiliary gate-board composition flashboard, realizes that flashboard two sides are close
Cover and sealing surface of seat are opened and closed without friction, and opening and closing is light, sealing performance is reliable, long service life.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Elastic wedging type flat gate valve as shown in Figure 1, including valve body 1, valve seat 2, flashboard, valve rod 8, valve deck 9, flashboard by
Main gate-board 4 and auxiliary gate-board 3 form, and are contacted between main gate-board 4 and auxiliary gate-board 3 using inclined-plane mutual cooperation, 4 upper end center of main gate-board
It being connect with 8 lower end of valve rod, main gate-board 4 is fixedly connected relative to 8 axis direction of valve rod, and relative to the radially movable connection of valve rod 8,
The limit plate 11 being fixedly connected with auxiliary gate-board 3 is equipped with above main gate-board 4, limit plate 11 is equipped with limit and adjusts screw 10, should
Limit adjusts screw 10 and is adjusted axially the radial disbalance moving distance between main gate-board 4 and auxiliary gate-board 3, axial tune mentioned here
Section refers to the adjusting along valve rod centerline direction, and radial disbalance moving distance refers to main gate-board 4 with respect to auxiliary gate-board 3 in valve rod
Guide pile 12 is arranged in 1 intracavity bottom of valve body in the distance that heart line direction moves up；It is characterized in that in main gate-board 4 and auxiliary gate-board 3
Between be equipped with elastic release unit, the elasticity release unit is used installs hook-type spring 6 between main gate-board 4 and auxiliary gate-board 3,
One end of the hook-type spring 6 is pressed in the made hook groove in 4 inclined-plane side of main gate-board, to main gate-board 4 under flashboard closed state
The elastic force to upper left is generated, the unlatching moment of main gate-board 4 is reduced, the other end passes through the spring eye on auxiliary gate-board 3 to secondary lock
3 sealing surface side of plate, and be fixedly mounted on the made installation inclined-plane 5 in 3 sealing surface side of auxiliary gate-board by nut 7, hook-type spring 6
Act on installation inclined-plane 5 on elastic force to auxiliary gate-board 3 generate to the right to pressure.Main gate-board 4 is pulled to rise in valve rod 8
When, the elastic force at 6 both ends of hook-type spring compresses main gate-board 4 to the left, and auxiliary gate-board 3 compresses to the right, keeps main gate-board 4 and auxiliary gate-board 3 de-
It is opened from sealing surface of seat；When flashboard is closed, 3 lower end of auxiliary gate-board is pressed on guide pile 12, and valve rod 8 pushes main gate-board 4 and secondary lock
Plate 3 is strutted to be sealed with 2 sealing surface compact of valve seat.Hook-type spring 6 can use V-arrangement spring.
6 one end of hook-type spring in 4 hook groove of main gate-board is T-shaped structure, is pressed on main gate-board on the upside of T-shaped structure
Between the left side wall and slot bottom of 4 hook grooves.
It is clearance fit between the two sidewalls of 4 hook groove of main gate-board and the T-shaped structure end of hook-type spring 6, makes hook-type spring 6
Space with flexible deformation.
Hook-type spring 6 is being uniformly arranged several perpendicular to 8 centerline direction of valve rod, keeps main gate-board 4 in opening-closing process
With the concentricity of auxiliary gate-board 3.
