Abstract
The utility model provides an elastic sealing butterfly valve, which comprises a valve body and is characterized in that a butterfly wrench is connected to the inside of the valve body via an upper rotary shaft and a lower rotary shaft, a sealing support and a retaining ring are disposed between the valve body and the butterfly wrench, one side of the sealing support near the inner end face of the valve body is equipped with a plurality of blind holes, springs contacting with the inner end face of the valve body are installed inside the holes, a seal base is disposed at a contacting position of the sealing support and the butterfly wrench, a groove is disposed on the outer lateral surface of the sealing support contacting with the valve body, an O-shaped ring is arranged inside the groove, the blind holes are arranged at equal intervals, and the springs include a pressure spring and a pull-type spring. Compared with the existing similar valves, the elastic seal butterfly valve has the advantages of having safe and reliable seal, increasing seal service life of 3-5 times, effectively prolonging the service life of the valve, having the springs with pre-compression capability capable of resisting over 1.5 times of the highest pressure of pipeline media and realizing the effect of wear compensations.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of elastic packing butterfly valve.
Background technique
At present in the valve of piping facility uses, substantially all carry out powerful contact seal,,, leakage occurs because that abrasion deformation causes is poorly sealed through interim use by the interference size of sealing.And the interference size that seals between paying can't compensate, and makes valve reduce the effect of sealing, can not work normally, enterprise's ordinary production of valve is used in influence greatly on the one hand, and cause serious economy loss, on the other hand, brought inconvenience also for the normal life of the people.
Summary of the invention
At the deficiency on the valve mechanism in the prior art, this practical purpose provides a kind of rational in infrastructure, and sealing is reliable, the elastic packing butterfly valve of long service life.
For achieving the above object, the technical solution adopted in the utility model provides a kind of elastic packing butterfly valve, the sealing butterfly valve includes valve body, in valve body by on rotating shaft and lower rotary shaft be connected with butterfly and pull, between pulling, valve body and butterfly be provided with sealed support and back-up ring, wherein: lean on a side of valve body interior edge face to have a plurality of blind holes at described sealed support, the spring that contacts with the valve body interior edge face is housed in this hole, pull the contact position sealed support and butterfly and be provided with sealing seat, on sealed support and outer side surface that valve body contacts, be provided with groove, O type circle is housed in this groove.
Described a plurality of blind hole is impartial the setting.
Described spring is pressure spring, pull the formula spring.
Effect of the present utility model is that this elastic packing butterfly valve is compared with existing similar valve, sealingly secure is reliable, can improve sealing life-span 3-5 doubly, effectively prolong the working life of valve, the precompressed ability of spring is wanted to resist more than 1.5 times of pipeline medium maximum pressure, and has the function of wear compensation.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated elastic packing butterfly valve structure of the present utility model.
As shown in Figure 1, 2, there is shown elastic packing butterfly valve structure of the present utility model, it comprises parts such as lower rotary shaft 1, valve body 2, O type circle 3, spring 4, sealed support 5, ring washer 6, sealing seat 7, butterfly are pulled 8, go up rotating shaft 9, pin 10.
Elastic packing butterfly valve structure of the present utility model, the sealing butterfly valve includes valve body, in valve body by on rotating shaft 9 and lower rotary shaft 1 utilize pin 10 to be connected with butterfly to pull 8, valve body 2 and butterfly are pulled 8 and are provided with sealed support 5 and back-up ring 6, lean on a side of valve body 2 interior edge faces to have a plurality of blind holes at described sealed support 5, these blind hole equalizations are arranged on the sealed support 5, the spring 4 that contacts with valve body 2 interior edge faces is housed in this hole, pull 8 contact position sealed support 5 and butterfly and be provided with sealing seat 7, on sealed support 5 and outer side surface that valve body 2 contacts, be provided with groove, generally be provided with two grooves, O type circle 3 is housed in this groove.
Elastic packing butterfly valve function of the present utility model is to realize like this.
Start transmission device, comprise manual, electronic, pneumatic, driving butterflies by last rotating shaft 9 pulls 8 and is rotated and closes, when rotating to when contacting with sealed support 5, driving sealing seat 7 trace moves, arrive closed position, pull 8 sealing surface and sealing seat 7 by butterfly and under the pressure of spring 4, seal, pass through the sealing of 5 of O type circle 3 guarantee valve bodies 2 and sealed supports simultaneously.
Butterfly is pulled 8 rotation when opening, and breaks away from sealing seat 7 gradually, and sealing seat 7 is moved forward under the pressure effect of spring 4, stops moving after touching ring washer 6, after butterfly is pulled 8 arrival enable possitions, finishes a circulation.
Such wearing and tearing that circulation produced all can be compensated by the precompression hydrodynamic reciprocating sealing seat 7 of spring 4, can improve the whole service life of sealing life and valve greatly, guarantee that sealing is reliable.
The scope that the utility model elastic packing butterfly valve uses is very extensive, can adopt unlike material to valve body 2, and as materials such as cast iron, copper, steel and stainless steels, its operating temperature is-150-+400 ℃.Sealing seat 7 materials of elastic packing butterfly valve can comprise: soft seal, as rubber, plastics, graphite and other flexible material; Also can seal firmly, as copper, stainless steel, titanium steel and can make the other materials of hard sealing.
Spring 4 in the illustrated elastic sealing structure of the utility model elastic packing butterfly valve can adopt pressure spring, pull the spring of formula spring and other form.
The utility model elastic packing butterfly valve is applicable on the pipeline of all different size calibers.
Although in conjunction with the accompanying drawings the utility model butterfly valve preferred embodiment is described above; but the utility model butterfly valve is not limited to above-mentioned embodiment; those skilled in the art is under enlightenment of the present utility model; do not breaking away under the scope situation that this practical information aim and claim protect; can also make a lot of forms, these all belong within the protection of the present utility model.
