Description
Technical field
The present invention relates in valve field, particularly relate to a kind of gate valve.
Background technology
Gate valve passes through the flashboard mobile realization along the lock seat guide-track groove above-below direction cut-out to pipeline.Gate valve has that fluid resistance is little, the advantage such as unrestricted that flows to of medium is 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 along with the prolongation of the time of use can increasing, the valve increasing leakage of generation can be caused；Two is that flashboard exists friction during opening and closing all the time with lock seat guide-track groove, and therefore operation moment of torsion is big, and is easily generated cut on flashboard and lock seat guide-track groove faying face, causes valve leak.
Summary of the invention
This is the most practical for the deficiencies in the prior art, proposes a kind of to operate high sealing, the wear-resisting type 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 sealing, wear-resisting type oil cargo tank gate valve, including regulation screw mandrel, handwheel, bearing, framework, flashboard, hanger, lock seat；Described bearing is fixedly connected in framework upper cross-beam；Described hanger is fixedly connected on flashboard upper end；Described regulation screw mandrel is vertically arranged, runs through bearing, a framework upper cross-beam, and threadeding with handwheel in upper end, lower end is hinged with hanger；Described flashboard, lock seat are placed in framework；Described flashboard is vertically arranged, and is plugged in from top to bottom in the guide-track groove that lock seat is vertically arranged, and with guide-track groove matched in clearance, can move up and down along guide-track groove；It thes improvement is that: be provided with chock in described lock seat guide-track groove；Described chock is arranged on flashboard, lock seat guide-track groove along between the fit clearance in media flow direction；Described lock seat, chock are respectively equipped with the cammed surface of phase wedging, and wherein the wedge surface of chock is shaped as up-small and down-big wedge shape.
In said structure, described lock seat, chock phase wedging cammed surface on all scribble wearing layer.
In said structure, the lock seat guide-track groove cell wall at the described chock back side is provided with some regulation bolts, and the end of described regulation bolt is resisted against the chock back side, can regulate chock along media flow direction.
In said structure, the cell wall of described lock seat guide-track groove both sides is provided with clamping screw；Described clamping screw runs through the cell wall of lock seat guide-track groove both sides, and its end can be resisted against the side of flashboard.
The present invention compared with prior art, has the positive effect that:
1. the present invention is provided with chock at flashboard, lock seat guide-track groove between the fit clearance in media flow direction, flashboard is when upwardly opening, and flashboard is rapidly separated with the cammed surface of chock phase wedging, it is to avoid phase mutual friction scratches, and operation moment of torsion is little；When flashboard cuts out downwards, flashboard and the rapid wedging of cammed surface of chock phase wedging, reliably seal, sealing will not be affected because using time length, therefore, significantly improve sealing reliability.
2. all scribble wearing layer in the cammed surface of lock seat, chock phase wedging, significantly improve the wearability in the cammed surface of lock seat, chock phase wedging, thus significantly improve the service life of gate valve.
3. the lock seat guide-track groove cell wall at the chock back side is provided with some regulation bolts, can regulate chock along media flow direction, so can regulator seat, the degree of tightness of chock phase wedging as required, improve the reliability sealed further.
4. the cell wall of lock seat guide-track groove both sides is provided with clamping screw, can lock flashboard when flashboard is closed.
