Abstract
The utility model discloses a novel butterfly valve, including valve body, valve rod and butterfly plate, the upper portion of valve rod is connected with the turbine case, the lower part of valve rod links to each other with the butterfly plate, the valve body is equipped with the seal receptacle with the butterfly plate contact site, be equipped with the recess on the seal receptacle, install the elastic component in the recess, the sealing washer is installed to the top of elastic component, the butterfly plate surface coating has corrosion -resistant layer. The utility model provides a valve can be after the sealing washer weares and teares, and the elastic component on the seal receptacle can push up the elastic ring to the butterfly plate under the elasticity of self, gives a compensation, guarantees sealing between butterfly plate and the seal receptacle, the corrosion -resistant layer on butterfly plate surface can improve the resistant corrosive effects of butterfly plate, increase of service life.
Description
Technical field
The utility model relates to a kind of production tree equipment, is specifically related to a kind of novel butterfly valve of production wellhead.
Background technique
Butterfly valve open-shut device is a discoidal butterfly plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.Butterfly valve standard-sized sheet is normally less than 90 ° to complete shut-down, and butterfly valve and butterfly bar itself do not have self-lock ability, in order to the location of butterfly plate, will install worm speed reducer additional on valve rod.Adopt worm speed reducer, butterfly plate not only can be made to have self-lock ability, make butterfly plate stop on arbitrary position, the operating characteristics of valve can also be improved.Traditional butterfly valve, generally include valve body, valve rod and butterfly plate, valve stem tip is connected with Worm gear case, Worm gear case is provided with its operation handwheel, the corresponding valve rod bottom position of valve body is provided with bottom, and valve body is corresponding with the place of connecting part, butterfly plate periphery is provided with seal ring, and seal ring can produce wearing and tearing in Long-Time Service process, the sealing effect of valve reduces, and can produce draining phenomenon.
Summary of the invention
For solving the problem, the utility model discloses a kind of novel butterfly valve, not only can locate the position of butterfly plate, and good sealing effect, extend the working life of valve.
A kind of novel butterfly valve, comprise valve body, valve rod and butterfly plate, the top of described valve rod is connected with turbine box, the bottom of described valve rod is connected with butterfly plate, described valve body and butterfly plate contacting part are provided with sealing seat, and described sealing seat is provided with groove, are provided with elastic component in described groove, the top of described elastic component is provided with seal ring, and described butterfly plate surface is coated with anti-corrosion layer.
As further improvement of the utility model, described butterfly plate is connected with valve rod by bolt.
As further improvement of the utility model, described elastic component is spring.
As further improvement of the utility model, described anti-corrosion layer is zinc coat or chromium coating.
Compared with prior art, the utility model tool has the following advantages and beneficial effect: after ring wear, the elastic component on sealing seat can under the elastic force of self by elastic ring top to butterfly plate, to a compensation, ensure the sealing between butterfly plate and sealing seat; The anti-corrosion layer on butterfly plate surface can improve the anticorrosion effect of butterfly plate, increases the service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is partial structurtes schematic diagram between butterfly plate and valve body in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
As shown in the figure, a kind of novel butterfly valve, comprises valve body 1, valve rod 2 and butterfly plate 3, and the top of valve rod 2 is connected with turbine box 4, is realized the location of butterfly plate by turbine box 4, prevents butterfly plate 3 from rotating under impact force.The bottom of valve rod 2 is stretched in valve body and is connected with butterfly plate 3, by bolt, butterfly plate 3 is arranged on stem bottom in the present embodiment.
In order to ensure the sealing between valve body 1 and butterfly plate 3, prevent oil gas from leaking from gap location, contact place at valve body 1 with butterfly plate 3 and be provided with sealing seat 5, sealing seat 5 is provided with groove, elastic component preferred spring in elastic component 6(the present embodiment is installed) in groove, the top of elastic component 6 is provided with seal ring 7, after there are wearing and tearing in seal ring, seal ring can eject to butterfly plate 3 under the elastic force of spring, compensate to valve body 1 and butterfly plate 3 one, ensure sealing effect, increase the service life, reduce the number of times just having changed seal ring.
In order to improve the decay resistance of butterfly plate 3, ensure that butterfly plate can use under the condition that corrosivity is strong, being coated with anti-corrosion layer 8 on butterfly plate 3 surface, can be zinc coat, also can be chromium coating.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises the technological scheme be made up of above technical characteristics combination in any.
