Abstract
A flat-wedge type gate valve of zero friction, which mainly solves the problem that the current gate valve is easy to be abraded and frozen in, has a high construction cost, and unlocking and servicing is inconvenient in valve well. The utility model is characterized in that a flashboard (2) has 2 sealing surfaces, namely a plane (3), and an inclined plane (4); the plane(3) is fixed with a resilient gasket (6) by means of screw(s); the valve base (1) end face tangent to the inclined plane (4) is provided with a gasket (7). The flat- wedge type gate valve of zero friction features an abrasion resistance and a frozen-in resistance.
Description
Technical field:
The utility model relates to the used gate valve of oil transportation in the oil recovery field, oil field, does not especially have friction flat-wedging type gate valve.
Background technique:
In oil recovery field, oil field, gate valve is the important component part on pipeline and the container.Used gate valve roughly is divided into flat gate valve and Wedge gate valve on pipeline and container at present, flat gate valve is owing to be equipped with spring on the valve seal seat, when opening flashboard both sides sealing face all the time with the spring friction, flashboard both sides sealing face is easy to wear like this, accelerate flashboard both sides sealing face rate of decay, shortened the working life of gate valve; Wedge gate valve is when opening, and is easily stuck because the flashboard both sides are the conical surface, need beat with hammer, makes and opens inconvenience, is unfavorable for applying.
The model utility content:
In order to solve the easy to wear and easily stuck problem of existing gate valve, the utility model provides a kind of nothing friction flat-wedging type gate valve, and this nothing friction flat-wedging type gate valve has not easy to wear and is difficult for stuck characteristics.
The technical solution of the utility model is: this nothing friction flat-wedging type gate valve comprises screw, valve seat and flashboard, and flashboard two sealing surfaces are respectively plane and inclined-plane, and by the flexible sealing gasket of screw, the valve seat end face that contacts with the inclined-plane is fixed with sealing gasket on the plane.
Elastic sealing gasket in the such scheme is a rubber; Screw has bearing up and down.
The utlity model has following beneficial effect: this nothing friction flat-wedging type gate valve is owing to take such scheme, because of flashboard one sealing surface is the plane, another sealing surface is the inclined-plane, just reduced the friction to flashboard when opening gate valve, flashboard is difficult for stuck, has prolonged the working life of gate valve, and be equipped with bearing up and down at screw, make and open conveniently, safe and reliable, help applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-valve seat among the figure, 2-flashboard, 3-plane, 4-inclined-plane, 5-bearing, 6-elastic sealing gasket, 7-sealing gasket.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: by shown in Figure 1, this nothing friction flat-wedging type gate valve comprises screw, valve seat 1 and flashboard 2,2 liang of sealing surfaces of flashboard are respectively plane 3 and inclined-plane 4, by screw rubber gasket 6 is arranged on the plane 3, valve seat 1 end face that contacts with inclined-plane 4 is fixed with sealing gasket 7, and bearing 5 is arranged on the screw.Because of flashboard 2 one sealing surfaces are planes 3, be added with rubber gasket 6, so just reduced wearing and tearing to flashboard 2, another sealing surface is inclined-plane 4, on valve seat 1, be fixed with sealing gasket 7, eliminated flashboard 2 stuck phenomena and produced, easy to operate, reduce maintenance load, prolonged the working life of gate valve, and on screw, be equipped with bearing 5, made and open conveniently, safe and reliable, help applying.So this nothing friction flat-wedging type gate valve has not easy to wear and is difficult for stuck characteristics.
Claims (3)
1, a kind of nothing friction flat-wedging type gate valve, comprise screw, valve seat (1) and flashboard (2), it is characterized in that: flashboard (2) two sealing surfaces are respectively plane (3) and inclined-plane (4), go up by the flexible sealing gasket of screw (6) on plane (3), and valve seat (1) end face that contacts with inclined-plane (4) is fixed with sealing gasket (7).
2, nothing friction flat-wedging type gate valve according to claim 1, it is characterized in that: elastic sealing gasket (6) is a rubber.
