Description
Technical field
The utility model is involved in valve field, particularly relates to a kind of gate valve.
Background technique
Gate valve is by the mobile cut-out that realize pipeline of flashboard along lock seat guide-track groove above-below direction.Gate valve has that fluid resistance is little, the advantage such as unrestricted that flows to of medium is widely used, but there is lower column defects in gate valve: one be between flashboard and lock seat guide-track groove in the gap in media flow direction along with the prolongation of service time can be increasing, valve can be caused to produce increasing leakage; Two is that flashboard exists with lock seat guide-track groove all the time and rubs in opening and closing process, therefore operates moment of torsion large, and easily produce cut on flashboard and lock seat guide-track groove junction plane, cause valve leak.
Summary of the invention
This is practical for the deficiencies in the prior art, proposes a kind ofly to operate the high-performance oil cargo tank gate valve that moment of torsion is little, sealing reliability is good.
The utility model is achieved through the following technical solutions technical goal.
High-performance oil cargo tank gate valve, comprises and regulates screw mandrel, handwheel, supporting base, framework, flashboard, hanger, lock seat; Described supporting base is fixedly connected in framework upper cross-beam; Described hanger is fixedly connected on flashboard upper end; Described adjustment screw mandrel is perpendicular to be put, run through supporting base, framework upper cross-beam, and upper end is threaded with handwheel, and lower end and hanger are hinged; Described flashboard, lock seat are all placed in framework; Described flashboard is perpendicular to be put, and is plugged in lock seat from top to bottom and erects in the guide-track groove put, with guide-track groove Spielpassung, can move up and down along guide-track groove; Its improvements are: be provided with chock in described lock seat guide-track groove; Described chock be arranged on flashboard, lock seat guide-track groove along media flow direction matching gap between; Described flashboard, chock are respectively equipped with the cammed surface of phase wedging, and wherein the wedge surface shape of chock is up-small and down-big wedge shape.
In said structure, the cammed surface of described flashboard, chock phase wedging all scribbles wearing layer; The junction plane of described flashboard and lock seat also scribbles wearing layer.
In said structure, the lock seat guide-track groove cell wall at the described chock back side is provided with some adjusting bolts, and the end of described adjusting 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 lock bolt; Described lock bolt 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 utility model compared with prior art, has following good effect:
1. the utility model flashboard, lock seat guide-track groove along media flow direction matching gap between be provided with chock, flashboard is when upwardly opening, and flashboard is separated rapidly with the cammed surface of chock phase wedging, avoid phase mutual friction scratch, and operation moment of torsion little; When flashboard cuts out downwards, flashboard and the rapid wedging of cammed surface of chock phase wedging, reliably seal, and can not affect sealing, therefore, significantly improve sealing reliability because service time is long.
2. the cammed surface of flashboard, chock phase wedging all scribbles wearing layer, significantly improves the wear resistance in the cammed surface of lock seat, chock phase wedging, thus significantly improve the working life of gate valve; The junction plane of flashboard and lock seat also scribbles wearing layer, significantly improves the wear resistance of flashboard and lock seat junction plane, improve the working life of gate valve further.
3. the lock seat guide-track groove cell wall at the chock back side is provided with some adjusting bolts, can regulate chock along media flow direction, like this can the degree of tightness of regulator seat, chock phase wedging as required, improves the reliability of sealing further.
4. the cell wall of lock seat guide-track groove both sides is provided with lock bolt, can lock flashboard when flashboard is in closed condition.
