Abstract
The utility model relates to a zero-friction flat wedge gate valve, and mainly solves the problem that the gate valve existing in the prior art is worn and deadlocked easily. The zero-friction flat wedge gate valve is characterized in that seal surfaces on the two sides of a flashboard (2) are a flat surface (3) and an inclined surface (4) respectively, an elastic sealing gasket (6) is fixed on the flat surface (3), the end surface of a valve seat (1) which is in contact with the inclined surface (4) is parallel to the inclined surface (4), and is fixed with a sealing gasket (7). The zero-friction flat wedge gate valve has the characteristic that the zero-friction flat wedge gate valve is not easily worn and deadlocked.
Description
Technical field
The utility model relates to the used gate valve of a kind of petroleum pipeline in the oil recovery field, oil field, particularly a kind of nothing friction flat-wedging type gate valve.
Background technique
In the 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.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the easy to wear and easily stuck problem of the existing gate valve that exists in the background technique, and a kind of nothing friction flat-wedging type gate valve is provided, and this nothing friction flat-wedging type gate valve has not easy to wear and is difficult for stuck characteristics.
The invention for solving the technical problem can reach by following technical solution: this nothing friction flat-wedging type gate valve comprises valve body, screw, valve seat, flashboard, described flashboard both sides sealing face is respectively plane and inclined-plane, be fixed with elastic sealing gasket on the plane, parallel with the valve seat end face of inclined-plane contact and be fixed with sealing gasket with the inclined-plane.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this nothing friction flat-wedging type gate valve is owing to adopt said structure, 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.
Among the figure: 1-valve seat, 2-flashboard, 3-plane, 4-inclined-plane, 5-bearing, 6-elastic sealing gasket, 7-sealing gasket, 8-blowdown valve, 9-valve body, 10-screw, 11-U type groove.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As shown in Figure 1, this nothing friction flat-wedging type gate valve comprises valve body 9, screw 10, valve seat 1, flashboard 2, and flashboard 2 tops connect screw 10.Described flashboard 2 both sides sealing faces are respectively plane 3 and inclined-plane 4, and by the flexible sealing gasket 6 of screw, described elastic sealing gasket 6 is a rubber pad on the plane 3; Parallel with valve seat 1 end face of inclined-plane 4 contact and inclined-plane 4 and be fixed with sealing gasket 7; Described screw 10 has bearing 5 up and down, blowdown valve 8 is equipped with in described valve body 9 bottoms, a free U type space is arranged at valve bottom is U type groove 11, use a period of time after, when U type groove 11 inner products have a large amount of mud to influence flashboard to close, open blowdown valve 8, can directly impurity be drained, improve the activity space of flashboard 2, make good sealing effect, if get pipeline medium when chemical examination on a small quantity, in blowdown valve, can easily take a sample.
When moving upward by the drive of the rotation between screw mandrel and the screw 10 flashboard 2, sealing gasket 7 tows out at once with inclined-plane 4 and contacts, and makes flashboard 2 without any under the friction situation, moves up easily, and valve opening makes medium pass through valve.Otherwise when the rotation drive flashboard 2 of screw mandrel and screw 10 moved downward, valve was closed immediately when the inclined-plane 4 of valve flashboard 2 contacts with sealing gasket 7, and friction is reduced to minimum.Also have elastic sealing gasket 6 simultaneously on flashboard 2 planes 3, make sealing effect more remarkable.Be equipped with bearing 5 on screw 10, make and open conveniently, safe and reliable, it is not easy to wear that this does not have friction flat-wedging type gate valve, is difficult for stuck.Easy to operate, reduce maintenance load, prolonged the working life of gate valve.
