Description
Technical field
The present invention relates in valve field, more particularly to a kind of gate valve.
Background technology
Gate valve passes through cut-out of mobile realization of the flashboard along lock seat guide-track groove above-below direction to pipeline.Gate valve have the advantages that fluid resistance it is little, it is medium flow to it is unrestricted be widely used, but column defects in the presence of gate valve：One be between flashboard and lock seat guide-track groove media flow direction gap as the prolongation of use time can be increasing, valve can be caused to produce increasing leakage；Two is that flashboard exists all the time with lock seat guide-track groove during opening and closing and rubs, therefore operates moment of torsion big, and is also easy to produce cut on flashboard and lock seat guide-track groove faying face, causes valve leak.
The content of the invention
This is practical for the deficiencies in the prior art, proposes a kind of operation high-performance oil cargo tank gate valve that moment of torsion is little, sealing reliability is good.
The present invention is achieved through the following technical solutions technical goal.
High-performance oil cargo tank gate valve, including adjust screw mandrel, handwheel, fulcrum bearing, framework, flashboard, hanger, lock seat；The fulcrum bearing is fixedly connected in framework upper cross-beam；The hanger is fixedly connected on flashboard upper end；It is described regulation screw mandrel be vertically arranged, through fulcrum bearing, framework upper cross-beam, upper end is threadedly coupled with handwheel, and lower end is hinged with hanger；The flashboard, lock seat are placed in framework；The flashboard is vertically arranged, and during the guide-track groove that lock seat is vertically arranged is plugged in from top to bottom, coordinates with guide-track groove gap, can move up and down along guide-track groove；It is theed improvement is that：Chock is provided with the lock seat guide-track groove；The chock is arranged on flashboard, lock seat guide-track groove between the fit clearance in media flow direction；The flashboard, chock are respectively equipped with the cammed surface of phase wedging, and the wedge surface of wherein chock is shaped as up-small and down-big wedge shape.
In said structure, in the flashboard, the cammed surface of chock phase wedging wearing layer is scribbled；Wearing layer is also coated with the flashboard and the faying face of lock seat.
In said structure, the lock seat guide-track groove cell wall at the chock back side is provided with some regulating bolts, and the end of the regulating bolt is resisted against the chock back side, can adjust chock along media flow direction.
In said structure, the cell wall of the lock seat guide-track groove both sides is provided with clamping screw；Through the cell wall of lock seat guide-track groove both sides, its end can be resisted against the side of flashboard to the clamping screw.
The present invention compared with prior art, has the positive effect that：
1. the present invention is provided with chock in flashboard, lock seat guide-track groove between the fit clearance in media flow direction, when upwardly opening, flashboard is rapidly separated flashboard with the cammed surface of chock phase wedging, it is to avoid phase mutual friction is scratched, and operates moment of torsion little；When closing downwards, flashboard and the rapid wedging of cammed surface of chock phase wedging are reliably sealed flashboard, will not affect to seal because of use time length, therefore, significantly improve sealing reliability.
2. wearing layer is scribbled in flashboard, the cammed surface of chock phase wedging, the wearability in lock seat, the cammed surface of chock phase wedging is significantly improved, so as to significantly improve the service life of gate valve；Wearing layer is also coated with flashboard and the faying face of lock seat, the wearability of flashboard and lock seat faying face is significantly improved, the service life of gate valve is further improved.
3. the lock seat guide-track groove cell wall at the chock back side is provided with some regulating bolts, can adjust chock along media flow direction, so can as needed regulator seat, chock phase wedging it is elastic, further improve the reliability of sealing.
4. the cell wall of lock seat guide-track groove both sides is provided with clamping screw, and flashboard can be locked when flashboard is closed.
