Abstract
The invention discloses a swing vortex check valve. The valve comprises a valve body, a valve cover, a valve flap and a valve plate, wherein the upper and lower inner walls of an inlet part of the valve body have an asymmetric structure, and the front side of the valve flap is provided with an oval concave surface, so that fluid forms a vortex field to increase seal moment. The invention has the advantages that: the swing vortex check valve has new breakthrough in aspects of mechanisms and processes, and the characteristic that the check valve can realize seal pressurization by means of backflow of a medium is achieved; and through implementation, compared with the conventional product, the swing vortex check valve has incomparable advantages in aspects of cost price and performance.
Description
Technical field
The present invention relates to a kind of valve, particularly a kind of rotary-open type eddy current safety check.
Background technique
Existing safety check is made up of valve body, flap, pin, valve gap, and valve body is up and down that arc symmetry, flap are the planes.This valve ubiquity complex process, the defective that processing cost is high; And the difficult acquisition excellent sealing performance of this structure; Cause the backflow of high-density medium easily; Therefore will improve constantly the requirement to check valve structure design and processes manufacture view, the especially development of structural design is so that valve technology is easy, cost is low, close tolerance seal etc.
Summary of the invention
To the deficiency of existing technology, the present invention provides a kind of processing cost low, the rotary-open type eddy current safety check of good seal performance.
To achieve these goals, the technological scheme that the present invention taked is:
A kind of rotary-open type eddy current safety check, the import position that comprises valve body, valve gap, flap and valve plate valve body up and down inwall is a non-symmetry structure, and the flap front is provided with oval concave surface, and making fluid form the vortex field increases sealed force moment;
Furtherly, pin, fork, nut and flap adopt the integrally casting structure, and technology is easy, cost is low.
Furtherly, valve plate upper end is connected with the axle of integral type, and spool with the valve plate plane parallel; Be provided with the groove of a placement axle in the valve body bonnet; Groove is other to have a lug edge, and a breach is arranged on the edge, and the link between valve shaft and the valve plate is positioned at breach; Axle rotates in groove, realizes the switching and the closure of valve plate;
Furtherly, the spill of the surface of the fluid inlet end of valve plate for from the center to the edge, shoaling gradually;
The flap joint is provided with compensating platform, makes flap can adjust sealing station voluntarily, very easily obtains higher sealed precision and economic processing technology.
Furtherly, the position that contacts with valve body of said valve plate is provided with a circle groove, is filled with rubber in the groove.
Described groove the best is a U type groove, and rubber seal increases sealability.
Beneficial effect of the present invention: rotary-open type eddy current safety check has all had new breakthrough from mechanism, on the technology, and has realized that safety check self can realize the characteristics of sealing supercharging, the enforcement of this patent by the backflow of medium; Be cost price, performance on year-on-year basis existing product all have incomparable advantage; Therefore, the development and application of this valve becomes novel product truly; It will replace the leading position of existing old product gradually; And increase foreign exchange earnings from exports, the outlet of homemade valve is significant, these research and development to rotary-open type eddy current safety check simultaneously have very important and practical meanings and academic significance.
Description of drawings
Fig. 1, structural representation of the present invention.
The structural drawing of Fig. 2, valve plate of the present invention.
Embodiment
A kind of safety check comprises valve body 1, valve gap 2 and valve plate 3, and the import position 11 upper and lower inwalls of valve body 1 are non-symmetry structure; Last inwall is the inclined-plane; Following inwall is the plane, and fluid comes in from import position 11 to increase the sealed force moment to valve plate 3 in vortex field of formation, back; The sealing effect of valve plate is better, longer service life.
Furtherly, valve plate 3 upper ends are connected with the axle 31 of integral type, and axle 31 is integral structures with valve plate 3; And axle 31 with valve plate 3 plane parallel, the inside of valve body 1 bonnet 2 be provided with one place axle groove 4, groove 4 is positioned at the top at fluid output position 12; There is a lug on groove 4 sides along 13, and a breach is arranged on the edge, and the link between valve shaft 31 and the valve plate 3 is positioned at breach; Axle rotates in groove, realizes the switching and the closure of valve plate;
Furtherly, the spill (similar be a pot shape) of the surface of the fluid inlet end of valve plate 3 for from the center to the edge, shoaling gradually.Reduce the impact of fluid like this, just in time form the vortex field together with non-symmetry structure.
Furtherly, the position that contacts with valve body 1 of said valve plate 3 is provided with a circle groove, is filled with rubber in the groove, like this and the contact position of valve body through rubber seal.Groove the best is a U type groove.
Beneficial effect of the present invention: valve body entrance point inwall adopts non-symmetry structure, makes fluid form the vortex field, increases sealed force moment; Valve plate adopts the suspension type framework, and is easy to process, and machining accuracy reduces, and valve board structure is simple, and cost is low, and spill and rubber seal increase sealing surface.
