Abstract
The utility model discloses a taper type circular arc buffering butterfly valve sealing washer, wherein, a taper type circular arc buffering butterfly valve sealing washer includes the valve body, the inside butterfly plate that is provided with of valve body, be provided with the butterfly valve sealing washer between butterfly plate and the valve body, be the great circular arc recess in the middle of the butterfly valve sealing washer outer lane, the inner circle sealing washer both sides of butterfly valve sealing washer are the transition of big inclination conical surface and sealed face circular arc respectively, the butterfly valve sealing washer is hunch-up and butterfly plate linear seal in the middle of the arc with butterfly plate contact department, one side fixedly connected with handle of valve body. Through the structure, the contact interference fit area of the butterfly plate and the butterfly valve sealing ring is reduced in the process that the butterfly plate rotates in the butterfly valve sealing ring, so that the friction force generated when the butterfly plate rotates in the sealing surface of the butterfly valve is reduced, and the torsion of the butterfly plate rotating in the butterfly valve sealing ring is reduced.
Description
Technical Field
The utility model relates to a butterfly valve technical field, in particular to oblique cone formula circular arc buffering butterfly valve sealing washer.
Background
The butterfly valve is a regulating valve with simple structure, and can be used for on-off control of low-pressure pipeline media. The closing member (valve clack or butterfly plate) is a disc and rotates around a valve shaft to achieve opening and closing. Mainly comprises a valve body, a butterfly ring, a butterfly plate and a driving device. The butterfly plate is sleeved in the butterfly ring, two ends of the butterfly ring are pressed by the two valve bodies, the upper end of the butterfly plate is connected with a handle (a manual driving device), the butterfly ring is made of rubber, and the valve is sealed by depending on the compression amount of an inner hole of the butterfly ring and the outer ring of the butterfly plate.
The inner ring of the butterfly valve sealing ring of the existing butterfly valve is a cylindrical straight surface, the outer ring of the butterfly valve sealing ring of the existing butterfly valve is two small arc grooves, when the butterfly plate rotates, the inner ring of the butterfly valve sealing ring and the outer ring of the butterfly plate are in interference fit all the time, the opening and closing torsion of the valve is increased, and the service life of the butterfly valve sealing ring is shortened; the variable space pressed by the outer ring of the butterfly valve sealing ring and the valve body is small, and the service life of the butterfly valve sealing ring is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tapered circular arc buffering butterfly valve sealing washer to solve the problem that proposes in the above-mentioned background art.
In order to realize above-mentioned purpose, provide a tapered circular arc buffering butterfly valve sealing washer, include: the butterfly valve comprises a valve body, wherein a butterfly plate is arranged in the valve body, a butterfly valve sealing ring is arranged between the butterfly plate and the valve body, a large-arc groove is formed in the middle of the outer ring of the butterfly valve sealing ring, and two sides of the inner ring sealing ring of the butterfly valve sealing ring are respectively in arc transition between a large-inclination conical surface and a sealing surface.
According to the oblique cone type arc buffering butterfly valve sealing ring, the contact position of the butterfly valve sealing ring and the butterfly plate is in an arc shape, the middle of the contact position is arched, and the contact position is linearly sealed with the butterfly plate.
According to an oblique cone type circular arc buffering butterfly valve sealing ring, one side fixedly connected with handle of valve body.
According to the oblique cone type arc buffering butterfly valve sealing ring, the butterfly valve sealing ring is annular.
The utility model discloses an aim at solves one of the technical problem that exists among the prior art at least, provides a tapered arc buffering butterfly valve sealing washer, main innovation point:
1. compared with the prior art, the oblique cone type arc buffering butterfly valve sealing ring has the advantages that the contact interference fit area of the butterfly plate and the butterfly valve sealing ring is reduced in the rotating process of the butterfly plate in the butterfly valve sealing ring, so that the friction force generated when the butterfly plate rotates in the sealing surface of the butterfly valve is reduced, and the torsion force generated when the butterfly plate rotates in the butterfly valve sealing ring is reduced.
2. Compared with the prior art, this tapered circular arc buffering butterfly valve sealing washer, butterfly valve sealing washer outer lane are equipped with the orthodrome recess, and when butterfly valve sealing washer inner circle excessively extruded with the butterfly plate, the orthodrome recess can be out of shape to the outside, alleviates butterfly plate and the excessive extrusion of butterfly valve sealing washer inner circle, and it is longer to improve butterfly valve sealing washer life.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
