Abstract
The utility model provides a soft sealing butterfly valve, which consists of a valve body, a butterfly plate and a rubber sealing ring, and is characterized in that the valve body and the rubber sealing ring positioned on an inner side wall are adhesively bonded into a whole. The adhesive bonding can be achieved in the process of hot pressing vulcanization. The utility model has no occurrence of the deformation of the sealing ring, avoids the problems of difficult opening and closing of the butterfly plate and water leakage etc., and has the advantages of simple production process, low failure rate in the long-term use, greatly reduced maintenance and reduced the using cost.
Description
Technical field:
The utility model relates to the butterfly valve in the medium transport pipelines such as being applied in tap water, sewage, weak acid or weak base.
Background technique:
Butterfly valve is to be made of valve body and butterfly plate, and week offers seal groove in valve body, embedded sealing ring in the groove.The structural type of this setting-in, not only manufacturing process complexity, seal ring are installed difficulty, and, in long-term using process, usually occur, and cause that butterfly plate is opened difficulty, problem such as leak because of the seal ring distortion.
Summary of the invention:
Technical problem to be solved in the utility model provides that a kind of manufacturing process is simple, the soft sealing butterfly valve of good seal performance, keying reliable in function.
The technological scheme that the utility model technical solution problem is adopted is:
The utility model is made of valve body, butterfly plate and rubber seal.
Structural feature of the present utility model is described valve body with being positioned at rubber seal on its madial wall bonding is an integral body.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, rubber seal and valve body form overall structure in the utility model, thereby the seal ring distortion can not occur, and the butterfly plate of having avoided therefore bringing opens and closes difficulty and problem such as leak.
2, the utility model can pass through hot-press vulcanization technology, with mould shape, directly will be bonded in as the rubber body of seal ring on the valve body madial wall, production technology is simple.
3, rate of fault is low in the long-term using process of the utility model, can greatly reduce amount of maintenance, reduces user cost.
The drawing explanation:
Accompanying drawing is the utility model structural representation.
Embodiment:
Referring to accompanying drawing, present embodiment is made of valve body 1, butterfly plate 2 and rubber seal 3.
Shown in the figure, in the present embodiment, valve body 1 is an integral body with being positioned at rubber seal 3 on its madial wall bonding.
In concrete the enforcement, between rubber seal 3 and valve body 1 adhesive layer 4 is arranged, adhesive layer 4 is a tackiness agent.Can in the hot-press vulcanization process, directly carry out bonding.Specific practice be with rubber through vulcanizing autoclave by hot vulcanization, be bonded on the valve body madial wall that scribbles tackiness agent.
During experiment hydraulic pressure, pressure reaches 20Mpa does not still have water leakage phenomenon, keeps its excellent sealing performance.
