Less than good solution, the heat supply in winter phase, it can often see in the street, steam explosion, because valve uses a period of time
Afterwards, poorly sealed, the leakage phenomenon of appearance, the energy loss that these leakages are caused is considerable.In addition, spreading all over the water supply in city
Pipe network similarly has the phenomenon of the not tight caused evaporating, emitting, dripping or leaking of liquid or gas waste water resource of valve seal.Passed for poisonous and harmful medium
Defeated pipe network, with greater need for prevent leakage.Large bore valves once with heat supply or water supply line, it is most of open and close several times after will
Generation leakage phenomenon.Hundreds of times are undergone when dispatching from the factory and opens and closes experiment, but that is entered under conditions of valve both sides are without pressure difference
Capable, often there is larger pressure difference in valve its both sides in heat supply pipeline opening-closing process.Contain in medium molecule and medium
Contaminant particles wash away valve sealing face at a high speed, cause sealing surface to destroy.The process used time is turned off or on due to smaller diameter valve
Shorter, the time that medium washes away sealing surface is shorter, therefore the sealing surface of smaller diameter valve is hardly damaged.Large bore valves are not only closed
Close or open that the used time is longer, medium is longer to sealing surface flushing time during being turned on and off, and large diameter valve door sealing
The area in face is big, and sealing surface is somewhat destroyed, and is easy for forming larger leakage rate.

Heaved in the middle part of the medial surface of rubber blanket, it is to avoid sealing rubber pad excessive wear, the problem of effectively can solving in background technology.
To achieve the above object, the utility model provides following technical scheme：One kind is without infiltration flange butterfly, including valve
Body, the bosom position of the valve body is fixed with ring packing rubber blanket, and the lateral surface top of valve body is fixed with axle sleeve, valve body
Inner bottom be provided with axle bed, the inner rotation of axle bed is connected with rotating shaft, rotating shaft set through circular baffle plate of the upper end of rotating shaft, ring
Shape sealing rubber pad, valve body and axle sleeve and the top for extending to axle sleeve, the upper end of rotating shaft are fixed with square column, ring packing rubber blanket
Internal symmetry offer two air cavitys, two air cavitys are connected by air guide channel, positioned at rear side air cavity by valve cock and
Ft connection, the inside of two air cavitys is respectively and fixedly provided with support plate.
As a kind of optimal technical scheme of the present utility model, the quantity of the support plate is 12, and 12 support plates
Central axis around ring packing rubber blanket is angularly distributed.
As a kind of optimal technical scheme of the present utility model, the lateral surface left side of the ring packing rubber blanket and right side
Four retainer rings are equidistantly fixed with, the position of the medial surface correspondence retainer ring of the valve body offers neck.
As a kind of optimal technical scheme of the present utility model, circular baffle plate is consolidated by bolt in the side of the rotating shaft
It is fixed.
As a kind of optimal technical scheme of the present utility model, the left and right ends of the valve body are arranged with flange.
Compared with prior art, the beneficial effects of the utility model are：This without infiltration flange butterfly, good seal performance,
The dwell time of ring packing rubber blanket is longer when valve is closed, when flange butterfly is closed, air cavity inflation so that
Ring packing rubber blanket and circular baffle plate sealing are tight；Support plate prevents the inner side of the ring packing rubber blanket caused by bernoulli principle
Middle face is heaved, it is to avoid sealing rubber pad excessive wear.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：It is a kind of without infiltration flange butterfly, including valve body 2,
The bosom position of valve body 2 is fixed with the left of ring packing rubber blanket 7, the lateral surface of ring packing rubber blanket 7 and right side is equal
Four retainer rings 11 are equidistantly fixed with, the position of the medial surface correspondence retainer ring 11 of valve body 2 offers neck, the He of retainer ring 11
Neck is used cooperatively, and prevents ring packing rubber blanket 7 from sliding, and the lateral surface top of valve body 2 is fixed with axle sleeve 5, the left and right of valve body 2
