Abstract
A butterfly valve with a diversion protective ring comprises a valve body, a butterfly plate, a valve rod, a driving mechanism, an upper lining, a lower lining, a bottom cover, a valve seat and the diversion protective ring, wherein the diversion protective ring is fixed on the inner cavity wall of the valve body and located on the same plane with the central line of the inner cavity of the valve body. The butterfly valve with the diversion protective ring has small overflowing resistance so that the butterfly plate is free of erosive wear caused by fluid and is effectively protected, and the sealing performance of the butterfly valve can be kept for a long time. A soft seal part can be positioned on the butterfly plate. The butterfly valve with the diversion protective ring is especially suitable for the fluid with hard particles.
Description
Technical field
The utility model relates to a kind of butterfly valve, particularly relates to a kind of butterfly valve that the water conservancy diversion guard ring is installed.
Background technique
Butterfly valve because simple in structure, volume is little, easy to operate; In pipe-line system, be used widely, but no matter be centre-pivoted butterfly valve or eccentric-butterfly-valve, soft sealing butterfly valve or hard seal butterfly valve; Under open mode; The high-velocity fluid of pipeline center is washing away the cylindrical sealing surface of butterfly plate constantly, if fluid contains hard particles, then erosive wear is particularly serious; So there is following problem:, will make the sealability variation owing to the wearing and tearing of butterfly plate sealing surface after use a period of time even 1. new butterfly valve seal performance is good; 2., because the butterfly plate sealing surface is not wedge angle type, slight drag structure such as streamlined, caused flow resistance big; 3., now soft sealing butterfly valve can only place soft seal on the valve seat, can not place on the butterfly plate complex structure.
Summary of the invention
The utility model technical problem to be solved is: solve the problem that above-mentioned existing technology exists, and provide a kind of and cross that flow resistance is little, butterfly plate does not receive the fluid scouring wearing and tearing, effectively protect butterfly plate, be particularly useful for having the water conservancy diversion guard ring butterfly valve of hard particles fluid.
The technological scheme that the utility model adopts is: this water conservancy diversion guard ring butterfly valve; Comprise valve body, butterfly plate, valve rod, driving mechanism, go up lining, following lining, bottom, valve seat; And the water conservancy diversion guard ring is installed; The water conservancy diversion guard ring is fixed on the internal chamber wall of valve body, and the lumen centers line of water conservancy diversion guard ring and valve body is in same plane.
In the technique scheme, the water conservancy diversion guard ring is made up of 1 or 2 semicircular ring.
In the technique scheme, when butterfly plate was in maximum opening, the periphery radial spacing of the internal surface of water conservancy diversion guard ring and butterfly plate was the 3-30 millimeter.
In the technique scheme, the outside of water conservancy diversion guard ring is tapered slope or V-type face or streamline surface.
In the technique scheme, the two ends of water conservancy diversion guard ring embed the groove on the body cavity wall, are screwed.
In the technique scheme, the inner surface configuration of water conservancy diversion guard ring is corresponding with butterfly plate cylindrical shape.
In the technique scheme, the tapered inclined-plane that stream is met in the water conservancy diversion guard ring outside is processed into cutting edge.
1., fluid resistance is little the utility model has the advantages that:; 2., effectively protect butterfly plate cylindrical sealing surface not receive fluid scouring to wear and tear long service life; 3., keep good seal performance for a long time; 4., soft seal can place on the butterfly plate simplified structure; 5., be applicable to the fluid that contains hard particles.
Description of drawings
Fig. 1 is the utility model structural profile schematic representation;
Fig. 2 is A-A generalized section of Fig. 1.
Among the figure: 1-valve body, 2-water conservancy diversion guard ring, 3-butterfly plate, 4-valve rod, 5-stop pin, 6-driving mechanism, the last lining of 7-, 8-Sealing, lining under the 9-, 10-bottom, 11-valve seat.
Embodiment
Embodiment 1:Water conservancy diversion guard ring butterfly valve with single semicircular ring.
The water conservancy diversion guard ring butterfly valve of the utility model comprises valve body 1, water conservancy diversion guard ring 2, butterfly plate 3, valve rod 4, stop pin 5, driving mechanism 6, goes up lining 7, Sealing 8, following lining 9, bottom 10, valve seat 11, and the utility model has been set up water conservancy diversion guard ring 2 on the basis of existing butterfly valve; Water conservancy diversion guard ring 2 is one or two semi-circle structure, and for one-way fluid, water conservancy diversion guard ring 2 is provided with a semi-circle; For bidirectional fluid, water conservancy diversion guard ring 2 is provided with two semi-circlees, and water conservancy diversion guard ring 2 is the semicircle sheets that radius ratio butterfly plate 3 external diameters are big 3～30 millimeters; Its two ends are provided with the connection projection; During installation the projection at water conservancy diversion guard ring two ends is embedded in the groove that is provided with on valve body 1 internal chamber wall, be screwed, be installed in water conservancy diversion guard ring and valve body 1 lumen centers line on the valve body 1 in same plane; When butterfly plate 3 is in maximum opening; When just the lumen centers line of butterfly plate 3 and valve body 1 was in same plane, water conservancy diversion guard ring 2 just in time covered the cylindrical sealing surface of butterfly plate 3, and the periphery of the internal surface of water conservancy diversion guard ring 2 and butterfly plate 3 is apart from being 3～30 millimeters; Just in time protect butterfly plate 3 cylindrical sealing surfaces not worn and torn by fluid scouring; The fluoran stream surface of water conservancy diversion guard ring 2 cross sections is processed tapered inclined-plane or V-type face or streamline surface, can reduce on the one hand the resistance of convection cell, but foreign material such as cut staple, wire on the other hand; Ensure the proper flow of fluid, exempted the harm that fiber, wire twine butterfly plate.
Each processes a groove earlier in valve body 1 inner chamber fluoran stream surface both sides, and also each produces a projection earlier at the two ends of water conservancy diversion guard ring 2, projection and groove can form little Spielpassung, and projection is embedded in the groove and is screwed.The tapered face that stream is met in water conservancy diversion guard ring 2 outsides is processed into cutting edge; When butterfly plate 3 is in the maximum opening place; Water conservancy diversion guard ring 2 just in time covers the periphery of butterfly plate 3, and the periphery of the internal surface of water conservancy diversion guard ring 2 and butterfly plate 3 distance is 10 millimeters, and other structure is with to have butterfly valve now identical.
Embodiment 2:Water conservancy diversion guard ring butterfly valve with two semicircular ring.
Referring to Fig. 1, in two semicircular ring that water conservancy diversion guard ring 2 is installed at valve body 1 inner chamber two ends simultaneously, be applicable to the fluid of two-way flow, other structure is identical with embodiment 1.
