Abstract
The utility model discloses a seal structure for valve seats of soft seal butterfly valves. A groove is disposed between one side wall of a valve seat and the outer wall of a valve body, the groove is provided with a seal ring, a pressure bushing is disposed on the outside of the sealing ring, bolt holes are formed between the pressure bushing and the valve seat, and the bolt holes are corresponding to each other. The seal structure for valve seats of soft seal butterfly valves has the advantages of high temperature resistance, good sealability, convenient operation, no friction once opened and closed, and when closed, sealability is improved with the increase of the moment of the transmission mechanism, thereby improving sealability of the butterfly valves and prolonging service life of the butterfly valves.
Description
Technical field
The utility model relates to the valve base sealing structure of soft sealing butterfly valve.
Background technique
The butterfly plate of the valve base sealing 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 then.
At present, the valve base sealing 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.Because 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 provides a kind of valve base sealing 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 valve base sealing structure of soft sealing butterfly valve is provided with groove between valve seat one sidewall and the valve outer wall, is provided with seal ring in the groove, and the outer side pressure of seal ring is equipped with gland, has mutual corresponding bolt hole between gland and the valve seat.
Described gland has the pressure tongue that is complementary with groove, presses the tongue top to be pressed on the seal ring outside.
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
