Abstract
The utility model provides a vulcanized rubber's skew seal face central line butterfly valve body, because the special shape of the sealed face of vulcanized rubber central line butterfly valve body, solved rubber seal uncompensable, the butterfly plate closes the easy position of crossing, the leakage problem that rubber wear arouses, its technical scheme is: the valve comprises a rubber inner cavity and a valve body outer wall, wherein the rubber inner cavity is provided with a sealing surface and a non-sealing surface, the sealing surface is positioned between the non-sealing surfaces, the sealing surface and the valve body drift diameter axis have a certain inclination, and the sealing surfaces are parallel to each other. The advantages are as follows: the butterfly valve is simple and reasonable in structure, low in cost and reliable in sealing performance, friction in the rotation process of the butterfly plate is reduced due to the inclined surface adopted for rubber sealing, torque and rubber abrasion are reduced, and the service life of the valve is prolonged; the butterfly plate cannot be over-positioned when closed, and meanwhile, the leakage problem caused by abrasion can be solved through adjusting the closing position of the butterfly plate.
Description
Technical Field
The utility model relates to the valve field, specific central line butterfly valve body that says so.
Background
The valve is used as a control element in a pipeline, can be used for pipelines of various types of fluids such as air, water, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like, and mainly plays a role in cutting off and throttling. The center line butterfly valve is the most basic and common valve in the valve and plays an important role in daily life of people, and the rubber is used as an important sealing element in the soft sealing center line butterfly valve and directly influences the sealing performance of the butterfly valve.
Fig. 1 is a vulcanized rubber center line butterfly valve body widely used in the existing valve industry, and thus similar vulcanized rubber center line butterfly valve rubber seals uncompensable, and a butterfly plate is easy to be over-positioned when closed, and repeatedly rubs with the butterfly plate in the opening and closing process to cause abrasion, so that the sealing performance of the valve is reduced, the service life is seriously shortened, and once leakage occurs, a new valve body needs to be replaced, so that unnecessary economic loss is caused.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a vulcanized rubber's skew sealing face central line butterfly valve body has solved rubber seal uncompensable because the special shape of the sealed face of vulcanized rubber central line butterfly valve body, and the butterfly plate is closed and is crossed the position easily, and the leakage problem that rubber wear arouses.
The utility model discloses an above-mentioned problem is solved through following technical scheme: the utility model provides a vulcanized rubber's skew seal face central line butterfly valve body, includes rubber inner chamber and valve body outer wall, and the rubber inner chamber is equipped with sealed face and non-seal face, and its characterized in that sealed face is located between the non-seal face, and sealed face has certain inclination with valve body latus rectum axis, and sealed face is parallel to each other.
The utility model has simple and reasonable structure, low cost and reliable sealing performance, and the inclined plane adopted for sealing the rubber reduces the friction in the rotation process of the butterfly plate, lightens the torque and the rubber abrasion, and prolongs the service life of the valve; the butterfly plate cannot be over-positioned when closed, and meanwhile, the leakage problem caused by abrasion can be solved through adjusting the closing position of the butterfly plate.
Drawings
FIG. 1 is a view of a vulcanized rubber center line butterfly valve seat that is now widely used in the valve industry.
Fig. 2 is a schematic structural diagram of the present invention.
Part names of each serial number in the figure: 1. rubber inner cavity 2, valve body outer wall 3, valve body drift diameter axis
1-1, sealing surface 1-2, non-sealing surface.
Detailed Description
As shown in figure 2, the center line butterfly valve body of the oblique sealing surface of vulcanized rubber comprises a rubber inner cavity 1 and a valve body outer wall 2, wherein the rubber inner cavity 1 is provided with a sealing surface 1-1 and a non-sealing surface 1-2, and is characterized in that the sealing surface 1-1 is positioned between the non-sealing surfaces 1-2, the sealing surface 1-1 and a valve body drift diameter axis 3 have a certain inclination, and the sealing surfaces 1-1 are parallel to each other.
During the use, the contact time of butterfly plate and rubber reduces at the closing in-process, reduces the friction, because sealed face has the inclination, when the butterfly plate takes place to leak after closing 0, can close the butterfly plate to negative angle, can also realize sealing, the life of extension valve.
Finally, it is noted that the above examples are only intended to illustrate the technical solutions of the present invention and not to limit the same, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
