Abstract
The utility model provides a butterfly valve. The butterfly valve comprises a valve body, a butterfly plate, a valve rod and a lever. The butterfly plate is arranged in the valve body and fixedly connected with the valve body through the valve rod which is arranged on the valve body. The lever is arranged outside the valve body and fixedly connected with the valve rod. The butterfly valve is characterized in that the butterfly plate is provided with a convex disk and reinforcing ribs, the convex disk is located in the middle of the butterfly plate, one end of each reinforcing rib is connected with the convex disk, the reinforcing ribs are distributed on the butterfly plate in a radial shape, and the butterfly plate is further provided with an abrasion-resisting layer. The butterfly plate is provided with the convex disk and the reinforcing ribs, the strength of the butterfly disk is reinforced, and when water pressure is too high, the phenomenon that the butterfly plate generates large deformation when bearing overlarge force is avoided. The butterfly plate is coated with the abrasion-resisting layer, so that the butterfly valve has good leakproofness; meanwhile, abrasion resistance and corrosion resistance of the butterfly plate are enhanced, and the service life of the butterfly valve is prolonged.
Description
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of butterfly valve.
Background technique
Butterfly valve is one of the most frequently used valve in machinery industry, be widely used in and in engineering system, carry various corrosivity, on the pipeline of non-corrosive fluids medium, at present in the butterfly valve of piping facility uses, great majority are all to adopt Interference size or the single seal ring of sealing to seal, through interim use, the corrosion and seal ring also can be worn, make valve reduce the effect of sealing, easily there is the leakage of fluid and cisco unity malfunction, affect on the one hand the normal production of enterprise, cause serious economic loss, bring great inconvenience also on the other hand people's life.In addition, when carrying flowing medium, butterfly plate is in flowing medium because washing away, wear and tear or corroding, easily cause spool to damage, affected the sealability of butterfly valve, if the flow velocity of fluid is very fast, hydraulic pressure is excessive, after using a period of time, can cause the stressed excessive deformation of butterfly plate, impact is closed, and working life is short.
Chinese patent CN 202280849 U disclose a kind of anticorrosion antiwear butterfly valve, comprise valve body, be arranged on spool (or being valve plate) wherein, the valve shaft being connected with spool through valve body and the spanner that is contained in valve body outer end and is connected with spool, on the face relative with valve body of the outer of spool, be provided with frp layer.Glass fibre reinforced plastics (FRP) light weight is and hard, and non-conductive, mechanical strength is high, corrosion-resistant, and can well seal with butterfly valve outside after spool painting frp layer.After frp layer is coated in the outside of spool, slow down the wearing and tearing of the spool lining of original butterfly valve, can extend the working life of butterfly valve, provided cost savings, but do not solved hydraulic pressure stressed excessive yielding problem of butterfly plate when excessive.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of butterfly valve, comprise valve body, butterfly plate, valve rod, spanner, described butterfly plate is arranged in described valve body, described butterfly plate is fixedly connected with by the valve rod being arranged on valve body with described valve body, described spanner is arranged on outside valve body, and be fixedly connected with described valve rod, it is characterized in that: described butterfly plate is provided with protruding dish and strengthening rib, described protruding dish is positioned at described butterfly plate middle part, one end of described strengthening rib and described protruding dish join, and are distributed in radially on described butterfly plate, are also provided with wearing layer on described butterfly plate.
The number of described protruding dish is more than 1 or 1.
Described strengthening rib is evenly distributed on described butterfly plate.
The number of described strengthening rib is more than 3 or 3.
All there are described protruding dish and described strengthening rib in two surfaces of described butterfly plate.
Described protruding dish and described strengthening rib are symmetricly set on two surfaces of described butterfly plate.
Described wearing layer is arranged on the outer of butterfly plate or butterfly plate on the whole.
Described wearing layer is wear-resistant ceramic layer.
The thickness of described wearing layer is 1mm-6mm.
The beneficial effects of the utility model are: protruding dish and strengthening rib are set on butterfly plate, strengthened the intensity of butterfly plate, when hydraulic pressure is excessive, avoided the moderate finite deformation of the stressed excessive generation of butterfly plate, on butterfly plate, scribble wearing layer, make butterfly valve there is good sealing, also increased wear resistance and the corrosion resistance of butterfly plate simultaneously, extended the working life of butterfly valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of butterfly plate in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further explained to explanation.
In figure, 1, valve body, 2, butterfly plate, 3, valve rod, 4, spanner, 5, protruding dish, 6, strengthening rib, 7, wearing layer.
As shown in Figure 1 and Figure 2, butterfly plate 2 is arranged in valve body 1, butterfly plate 2 is fixedly connected with by the valve rod 3 through valve body 1 with valve body 1, spanner 4 is arranged on outside valve body 1, and be fixedly connected with valve rod 3, protruding dish 5 is set at the middle part of butterfly plate 2, the number of protruding dish 5 is 1, on butterfly plate 2, the outer rim of protruding dish 5 arranges strengthening rib 6, strengthening rib 6 is evenly distributed on butterfly plate 2 radially, the number of strengthening rib 6 is 4, in the outer of butterfly plate 2, coat wearing layer 7, wearing layer 7 is wear-resistant ceramic layer, and the thickness of wearing layer 7 is 2mm, 2 liang of surperficial symmetrical configuration of butterfly plate.
