Description
Technical field
The present invention relates to sealing valve technical field, is specially a kind of new soft sealing butterfly valve.
Background technology
Valve industry, as an important step of equipment manufacture, plays very important in the national economic development
Effect.Since the country of China valve manufacture industry level still has certain gap, a lot of high parameters, high temperature compared with international most advanced level
High pressure, the critical valves original of high pound level rely on import always, such as Europe OMAL brands are always state's inner valve application industry
Main selecting object.
Butterfly valve is called flap valve, is a kind of regulating valve simple in structure, what the switch available for low pressure pipeline medium controlled
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, a kind of valve of open and close is reached around valve shaft rotation, valve can
For controlling all kinds such as empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium
The flowing of fluid.It is main on pipeline to play cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Rotated around the axis of its own, so as to achieve the purpose that keying or adjusting.Butterfly valve standard-sized sheet is typically less than 90 ° to fully closed, butterfly valve
There is no self-lock ability in itself with butterfly bar, for the positioning of butterfly plate, to install worm reducer additional on valve rod.Using worm gear reducer
Device, can not only make butterfly plate have self-lock ability, butterfly plate is stopped at an arbitrary position, moreover it is possible to improve the operating characteristics of valve.
The characteristics of industrial special butterfly valve can high temperature resistant, be applicable in that pressure limit is also higher, and valve inside nominal diameter is big, and valve body uses carbon steel system
Make, the sealing ring of valve plate replaces rubber ring using becket.Large high-temperature butterfly valve uses steel plate welding manufacture, is mainly used for high temperature
The cigarette air passage of medium and gas piping.
At present, the butterfly valve used on medical equipment has good sealing performance, but after its long-time use, leakproofness
It can reduce, cause service life short, and be easily caught broken medicine.
The content of the invention
It is an object of the invention to provide a kind of new soft sealing butterfly valve, to solve proposed in the above background technology ask
Topic.
To achieve the above object, the present invention provides following technical solution：A kind of new soft sealing butterfly valve, including upper valve body,
Lower valve body, handle and valve rod, the upper valve body and lower valve body one end are fixed by clip, and the clip is equipped with draw ring, described
Upper valve body and the lower valve body other end are fixed by slip-knot bolt, and the slip-knot bolt is movably arranged on lower valve body tip inside pin
On, collar nut is movably installed with the slip-knot bolt, the ball to match with slip-knot bolt is fixed with the collar nut
Head, butterfly plate is respectively and fixedly provided with the upper valve body and lower valve body, and square tube seat, the square tube are fixed in the upper valve body and lower valve body one end
Seat inner cavity sets valve rod, the handle outside valve rod connection；The positioning pin also sets up O-shaped sealing with square tube seat junction
Circle；Butterfly plate is made of flexible material, and the upper valve body and lower valve body fix contact position and be installed with sealing ring.
Preferably, the butterfly plate is porous plate, is coated with rubber layer.
Preferably, the quantity of sealing ring is 2, and material is polytetrafluoroethylene (PTFE).
Compared with prior art, the beneficial effects of the invention are as follows：
（1）Structural principle of the present invention is simple, easy to use, good seal performance, and service life is grown.
（2）In the present invention, rubber layer is coated with butterfly plate outer wall, can effectively prevent from being caught broken medicine.
