Description
Technical field
The present invention relates to switching control device technical field, more particularly to a kind of double seals butterfly valve.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in construction, what the switch available for low pressure pipeline medium was controlled
Butterfly valve refers to closure member（Flap or butterfly plate）For disk, a kind of valve of open and close is reached around valve rod 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.
During butterfly plate rotates realization open and close around valve rod, because butterfly plate has certain thickness, rotated
Butterfly plate edge can cause butterfly plate to wear and tear with valve body generation friction unavoidably in journey, be flowed with the extension of use time plus in butterfly valve
The corrosiveness of body, often just occurs that butterfly plate is poorly sealed after closing, the phenomenon that fluid continues seepage occurs.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of double seals butterfly valve, it is to avoid butterfly plate occurs close after closing
The problem of envelope is not tight.
The present invention is achieved through the following technical solutions, and there is provided a kind of double seals butterfly valve, the double seals butterfly valve, including valve
Body, the valve rod for being rotatably connected on valve inner and the butterfly plate being fixed on valve rod, in addition to it is respectively and fixedly installed to valve inner
Semicircle shape sealing ring in the correspondence cambered surface of both sides, the semicircle shape sealing rings of the valve body both sides along valve body axis projection it is non-overlapping and
Formed a full circle, valve body close when, dish plate both sides respectively with corresponding semicircle shape sealing ring fitted seal, formed an entirety
Sealing ring；The semicircle shape sealing ring outer arc degree is adapted with valve inner cambered surface radian, the semicircle shape sealing ring inner arc
Face extends along valve body axis direction；The butterfly plate two ends are respectively equipped with chamfering, the both sides semicircle shape sealing ring and butterfly plate two ends
Sealing slope is respectively equipped with chamfering mating surface.
When direction where butterfly plate is in 90 degree of angles with direction where valve body, now butterfly plate is in opening, and liquid is just
Permanent current leads to, when butterfly plate is rotated counterclockwise into 90 degree, and now surface chamfer is distinguished with surface chamfer on rear side of butterfly plate right-hand member on front side of butterfly plate left end
Contacted with both sides semicircle shape sealing ring, chamfering coordinates with sealing slope, realizes sealing, now butterfly plate is closed, liquid
Can not normally it circulate.
Preferably, the chamfering is provided with the Anti-seepage mechanism for playing sealing function with semicircle shape sealing ring mating surface.
Preferably, the Anti-seepage mechanism includes the hole for injecting glue being arranged on body wall and is arranged on semicircle close
Annular seal groove and ring-shaped pouring glue groove in seal, the annular seal groove are connected with ring-shaped pouring glue groove by glue injection channel, institute
Hole for injecting glue is stated to connect with ring-shaped pouring glue groove.If, which there is leakage, in valve by hole for injecting glue to be injected into ring packing by fluid sealant
Sealed in groove, so that the problem of effectively solving valve leaks.
As an improvement, the annular seal groove is located on sealing slope.
As an improvement, the semicircle shape sealing ring is provided with connecting portion, the connecting portion and sealing inclined along valve body horizontal direction
Domatic is into turning, and the annular seal groove is located at corner.
Preferably, the Anti-seepage mechanism includes elastic sealing gasket and the pressing plate for fixing elastic sealing gasket.Elasticity
Sealing gasket and pressing plate, which coordinate, can play secondary seal effect, even if butterfly plate is connected not close with semicircle shape sealing ring, also will not
There is fluid seepage.
As an improvement, sealing slope end is provided with shoulder, the elastic sealing gasket is located in shoulder, and the pressing plate is consolidated
Dingan County is outside elastic sealing gasket.
As an improvement, sealing slope end is provided with shoulder, the elastic sealing gasket includes base portion and affixed with base portion
Empennage together, forms angle between the base portion and empennage, the base portion is located in shoulder, and the empennage is located at sealing inclined
On inclined-plane where slope, the pressing plate is fixedly mounted on elastic sealing gasket base exterior.The plane where butterfly plate is parallel with valve body
When, butterfly plate chamfering compresses empennage so that empennage is close to seal slope, so as to play sealing effectiveness.
Beneficial effects of the present invention are：
1st, set semicircle shape sealing ring itself can just play sealing well with butterfly plate cooperation in valve inner cambered surface to imitate
Really, plus the setting that ramp structure and the chamfer of butterfly plate two are sealed in semicircle shape sealing ring, the cooperation of sealing slope and chamfering
Sealing effectiveness is further enhanced, is sent out while the setting of the chamfer of butterfly plate two avoids butterfly plate in rotation process with valve interior wall
Raw friction, has fundamentally prevented butterfly plate abrasion, has improved butterfly plate service life.
2nd, fluid sealant can be injected into annular seal groove by hole for injecting glue and be sealed when valve is revealed, so that
The problem of effectively solving valve leaks, it is easy to operate without carrying out valve body dismounting.
3rd, elastic sealing gasket and pressing plate, which coordinate, can play secondary seal effect, even if butterfly plate is connected with semicircle shape sealing ring
It is not close, be also not in fluid seepage.
4th, simple in construction, using effect substantially, with extensive economy and social value.
