Abstract
The utility model relates to the field of industrial pipeline valves, in particular to a soft seal eccentric butterfly valve. The soft seal eccentric butterfly valve comprises a valve body, a valve plate is arranged in the valve body, an upper rotary shaft and a lower rotary shaft are arranged on the upper portion and the lower portion of the valve body respectively, the valve plate is respectively fixed with the upper rotary shaft and the lower rotary shaft through an upper fixing pin and a lower fixing pin, the lower rotary shaft is connected with the bottom of the valve body through a lower shaft sleeve, sealing packing is arranged at the contact portion of the upper rotary shaft and the valve body and is compressed and fixed through an upper gland arranged at the top of the valve body, and a high temperature resistant sealing ring is arranged on the end face of the valve plate. The soft seal eccentric butterfly valve has the advantages that soft seal of the high temperature resistant sealing ring is adopted by the eccentric butterfly valve, when the eccentric butterfly valve is closed, the butterfly valve sealing ring and the valve body are in contact closing, the eccentric valve plate is not in direct contact friction with the valve body, therefore, the valve plate cannot be extruded and scratched by the valve body, the service life of the valve plate is prolonged, the sealing performance is improved due to the utilization of the soft seal of the high temperature resistant sealing ring, and therefore the service life of the eccentric butterfly valve is prolonged.
Description
Technical field
The utility model relates to industrial pipeline valve field.
Background technique
Eccentric-butterfly-valve is applied to metallurgy at present, electric power, petrochemical industry, and on draining and urban construction industrial pipeline, as adjust flux and block fluid use, mainly to be used widely on some Urban High Temperature pipeline base facilities and high temperature chemical engineering industry pipeline base facility, therefore, working life to eccentric-butterfly-valve and sealability require high, hard sealing structure and present stage is applied in that eccentric-butterfly-valve on these fields adopts in order to adapt to hot environment, hard sealing structure is that eccentric butterfly plate contacts closure with valve body, due to the eccentric butterfly plate of this sealing configuration with valve body all the time in pushing, scraping state, resistance is apart from large, friction is fast, therefore working life is not long, and cause sealability to reduce.
Summary of the invention
The purpose of this utility model is: provide a kind of soft seal eccentric-butterfly-valve, good sealing effect, long service life.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of soft seal eccentric-butterfly-valve, comprise valve body, in valve body, be provided with valve plate, it is characterized in that: described valve body is respectively equipped with rotating shaft and lower rotary shaft up and down, described valve plate fixes with upper rotating shaft and lower rotary shaft respectively by upper fixing pin and lower fixing pin, and described lower rotary shaft is connected with valve body bottom by Lower shaft sleeve, is provided with stuffing box packing in upper rotating shaft and valve body contacting part, and the upper press cover being provided with by valve body tip position is fixed, above-described valve plate end face is provided with refractory seal ring.
Above-described valve body top is also provided with handwheel, and described handwheel is connected with upper rotating shaft, and can drive rotating shaft rotation.
The effect that the utility model reaches is: due to the soft seal of eccentric-butterfly-valve employing refractory seal ring, when closed eccentric-butterfly-valve, butterfly valve seal circle contacts closed with valve body, eccentric valve plate not with the direct contact friction of valve body, therefore valve plate can be by valve body extruding scraping, increase the working life of valve plate, and utilized high temperature resistant cushion rubber soft seal sealability also to improve, therefore made increase the working life of eccentric-butterfly-valve.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1. handwheel; 2. upper press cover; 3. stuffing box packing; 4. go up rotating shaft; 5. valve body; 6. go up fixing pin; 7. valve plate; 8. descend fixing pin; 9. lower rotary shaft; 10. Lower shaft sleeve; 11. refractory seal rings.
Embodiment
From accompanying drawing 1, the utility model comprises valve body 5, in valve body 5, be provided with valve plate 7, described valve body 5 is respectively equipped with rotating shaft 4 and lower rotary shaft 9 up and down, described valve plate 7 fixes with upper rotating shaft 4 and lower rotary shaft 9 respectively by upper fixing pin 6 and lower fixing pin 8, described lower rotary shaft 9 is connected with valve body 5 bottoms by Lower shaft sleeve 10, be provided with stuffing box packing 3 in upper rotating shaft 4 with valve body 5 contacting parts, and the upper press cover 2 being provided with by valve body 5 tip positions is fixed, above-described valve plate 7 end faces are provided with refractory seal ring 11.Above-described valve body 5 tops are also provided with handwheel 1, and described handwheel 1 is connected with upper rotating shaft 4, and can drive rotating shaft 4 to rotate.
When use, clockwise rotate the first run 1, valve plate 7 refractory seal ring 11 above departs from valve body 5 inside, eccentric disk version is opened, at this moment pipe interior fluid flows through eccentric-butterfly-valve, rotate counterclockwise handwheel 1, valve plate 7 refractory seal ring 11 is above close to valve body 5 inside, make valve plate 7 and valve body 5 tight closed, fluid is tightly dammed, because adopting the soft seal of refractory seal ring 11, eccentric-butterfly-valve designs, when closed eccentric-butterfly-valve, butterfly valve seal ring contacts closed with valve body 5, valve plate 7 not with the direct contact friction of valve body 5, therefore valve plate 7 can not pushed scraping by valve body 5, increase the working life of valve plate 7.
Claims (2)
1. a soft seal eccentric-butterfly-valve, comprise valve body, in valve body, be provided with valve plate, it is characterized in that: described valve body is respectively equipped with rotating shaft and lower rotary shaft up and down, described valve plate fixes with upper rotating shaft and lower rotary shaft respectively by upper fixing pin and lower fixing pin, and described lower rotary shaft is connected with valve body bottom by Lower shaft sleeve, is provided with stuffing box packing in upper rotating shaft and valve body contacting part, and the upper press cover being provided with by valve body tip position is fixed, above-described valve plate end face is provided with refractory seal ring.
2. soft seal eccentric-butterfly-valve according to claim 1, is characterized in that: described valve body top is also provided with handwheel, and described handwheel is connected with upper rotating shaft, and can drive rotating shaft rotation.
