Abstract
The utility model discloses a valve core mounting structure of a soft seal butterfly valve, which includes a valve core body, wherein a mounting base is arranged on the outer side of the valve core body; vertical mounting holes are formed at the upper and the lower end of the mounting base respectively; a cavity is formed between the mounting holes at the upper end and the lower end respectively; and an upper half shaft and a lower half shaft are fitted in the vertical mounting holes respectively. The valve core mounting structure has the advantages of high temperature resistance, high tightness, light operation, no abrasive friction during open and close, capable of compensating the tightness along with increase of the torque of a transmission mechanism during close, and capabilities of improving the tightness of the butterfly valve and prolonging the service life thereof.
Description
Technical field
The utility model relates to the spool mounting structure of soft sealing butterfly valve.
Background technique
The butterfly plate of the spool mounting structure of soft sealing butterfly valve is installed on the diametric(al) of pipeline.In the butterfly valve body cylindrical channel, the disc butterfly plate rotates around axis, and angle of swing is between 0 ° ~ 90 °, and when rotating to 90 °, valve is the board full-gear.
At present, the spool mounting structure of soft sealing butterfly valve obtains using very widely in many fields such as oil, chemical industry, metallurgy, water power as a kind of parts that are used for realizing pipe-line system break-make and flow control.In known butterfly valve technology, its seal form adopts sealing configuration more, and sealing material is rubber, teflon etc.Due to the restriction of structure characteristic, be not suitable with high temperature resistant, high pressure and corrosion-resistant, the industry such as resistance to wear.
The model utility content
The purpose of this utility model is to provide a kind of spool mounting structure of soft sealing butterfly valve, has high temperature resistantly, and sealing is strong, operate light, open and close without friction, come compensation sealing along with the moment of driving mechanism increases when closing, improved the sealability of butterfly valve and the advantage that increases the service life.
The technical solution of the utility model is as follows:
The spool mounting structure of soft sealing butterfly valve, include the spool body, outside the spool body, with fitting seat, described fitting seat upper and lower end has vertical mounting hole, have cavity between the vertical mounting hole of upper and lower end, be combined with respectively semiaxis, lower semiaxis in vertical mounting hole.
Described spool body outer side wall has groove.
The utlity model has high temperature resistantly, sealing is strong, operates lightly, opens and closes without friction, comes compensation sealing along with the moment of driving mechanism increases when closing, and has improved the sealability of butterfly valve and the advantage that increases the service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, the spool mounting structure of soft sealing butterfly valve, include spool body 1, spool body 1 outside is with fitting seat 2, fitting seat 2 upper and lower ends have vertical mounting hole, have cavity 3 between the vertical mounting hole of upper and lower end, be combined with respectively semiaxis 4, lower semiaxis 5 in vertical mounting hole, spool body outer side wall has groove.
Claims (2)
1. the spool mounting structure of soft sealing butterfly valve, include the spool body, it is characterized in that: the spool body outside is with fitting seat, described fitting seat upper and lower end has vertical mounting hole, have cavity between the vertical mounting hole of upper and lower end, be combined with respectively semiaxis, lower semiaxis in vertical mounting hole.
