Description
Technical field
The utility model relates to a kind of butterfly valve that uses in the carbon black industry, especially a kind of butterfly valve with the anti-jamming outside fix guide structure of transmission shaft.
Background technique
Along with the progress of science and technology, the industrial automation controlling level is in continuous improve, thus to the requirement of the reliability of modulating valve in the process control, Economy also in continuous raising.This just also has higher requirement to the valve body structure.In the carbon black industry oil system, the temperature height, pressure reduction is big, and it is big to contain its hardness of fine particle, and erosion is strong.In the air system, temperature is higher relatively, and wind-warm syndrome is up to more than 600 degrees centigrade.In prior art, position structure in existing carbon black transmission shaft position structure adopts, under the situation of some high temperature because the material non-homogeneous expansion is even, locating piece and guide sleeve easily and axle kills, increased the frictional force with transmission shaft, transmission shaft easily twists off.Particle in the medium is easy to enter into locating piece and guide sleeve in addition, and cover is easily stuck with transmission shaft, causes the valve cisco unity malfunction, and device stops and causes great economic loss.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and can effectively reduce the stuck phenomenon that valve occurs in running, increase work efficiency, increase the service life, be convenient to process, assemble, change the butterfly valve with the anti-jamming outside fix guide structure of transmission shaft of valve body structure quick-wear part.
The technological scheme that provides according to the utility model, described butterfly valve with the anti-jamming outside fix guide structure of transmission shaft, comprise butterfly valve body, butterfly valve plate and transmission shaft three big main parts, transmission shaft passes valve plate and is fixed into one with pin, assemble with valve body, upper fixed has upper junction plate on the top of butterfly valve body, upper junction plate is fixed on the valve body by last attachment post, in the installation through hole of upper junction plate, the top outboard bearing is installed, the tip portion of described transmission shaft is installed in the bearing hole of top outboard bearing, below the bottom of butterfly valve body, be fixed with lower connecting plate, lower connecting plate is fixed on the valve body by following attachment post, the bottom outboard bearing is installed in the installing blind of lower connecting plate, and the bottom of described transmission shaft is installed in the bearing hole of bottom outboard bearing.
Be provided with seal ring at the butterfly valve body internal fixation, described seal ring and butterfly valve plate are and are sealed and matched.
Compared with the prior art the utility model has the following advantages:
1, owing to adopt the anti-jamming outside fix guide structure of carbon black, transmission shaft does not have stuck phenomenon, has improved the butterfly valve plate Location accuracy, guarantees the stable work of butterfly valve valve, prolongs its working life.
2, the friction between the part reduces, open and close more flexible, thereby the wearing and tearing that reduce part have reduced the probability of maintenance, have reduced cost, bring bigger economic benefit.
3, this structural orientation is reliable, and steering capability is good, has solved easy the to be stuck problem of butterfly valve in the carbon black industry effectively.
4, this structure has reduced the assembling of part in assembly process, assembles more simply, time saving and energy saving, improves efficiency of assembling.
