Abstract
More particularly to a kind of soft sealer of the utility model.Including valve body, butterfly plate is provided with valve body, valve interior wall is provided with the valve seat coordinated with butterfly plate sealing, and valve seat is provided with the seal for coordinating with butterfly plate sealing；Seal includes front-end and back-end, and front end seals with the butterfly plate and coordinates, and rear end is provided with external screw thread, groove is provided with seal rear end corresponding position on valve seat, and the internal thread being engaged with external screw thread is provided with groove；Thread locking adhesive is coated with the external screw thread of seal rear end.The utility model can reduce the medium punching press that seal is subject to, so as to mitigate the abrasion of seal, extend the service life of seal；And seal and butterfly plate corresponding position are set to zigzag, improve sealing effectiveness；Meanwhile, this soft sealer by setting ultrasonic transmitter and ultrasonic receiver, can the timely early warning when butterfly valve seal effect declines, so as to facilitate user to be changed to seal or searched the sealing problem of butterfly valve presence in time.
Description
Technical field
The utility model is related to valve field, more particularly to a kind of soft sealer.
Background technology
In the prior art, butterfly valve due to small volume, lightweight, installing space it is small, and bore specification is far longer than other
The advantages of valve class, it is increasingly becoming the most wide valve of range of application.Its sealing ring of most butterfly valve is arranged on butterfly plate at present,
Being washed away by medium during valve opening influences larger, and sealing ring is easily damaged, so as to influence the sealing of butterfly valve to imitate
Really.Meanwhile, seal and butterfly plate correspondence position are circular arc in the prior art, are very easy to abrasion, can further influence butterfly valve
Sealing effectiveness.
Utility model content
The utility model provides a kind of soft sealer, solves the problems, such as techniques discussed above.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of soft sealer, including valve body, it is described
Be provided with butterfly plate in valve body, the valve interior wall is provided with the valve seat coordinated with butterfly plate sealing, the valve seat be provided with for
The seal that the butterfly plate sealing coordinates；The seal includes front-end and back-end, and the front end seals with the butterfly plate and coordinates,
The rear end is provided with external screw thread, and groove is provided with seal rear end corresponding position on the valve seat, is set in the groove
There is the internal thread being engaged with the external screw thread；Thread locking adhesive is coated with the external screw thread of the seal rear end.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the seal front end and the butterfly plate correspondence position are zigzag.
Further, sealing clamping ring is provided with the groove, the seal rear end is fixed on described by sealing clamping ring
In groove on valve seat.
Further, the material of the sealing clamping ring is NBR, EPDM or PTFE.
Further, also including ultrasonic transmitter and ultrasonic receiver, the ultrasonic transmitter is arranged on outside valve body
On side, the ultrasonic receiver is arranged on valve seat at seal.
The beneficial effects of the utility model are：Be arranged on seal on valve body by the utility model, reduces seal and receives
The medium punching press arrived, so as to alleviate the abrasion of seal, extends the service life of seal；And by seal and butterfly plate pair
Answer and zigzag is set at position, improve the sealing effectiveness of butterfly valve in the case of sealing part abrasion；Meanwhile, this soft sealer leads to
Cross setting ultrasonic transmitter and ultrasonic receiver, can the timely early warning when butterfly valve seal effect declines so that convenient use
The sealing problem of butterfly valve presence is changed or is searched to seal in time in family.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model soft sealer.
Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in figure 1, be the structural representation of the present embodiment soft sealer, including valve body 1, is provided with the valve body 1
Butterfly plate 2, the inwall of the valve body 1 be provided with the butterfly plate 2 sealing coordinate valve seat, the valve seat be provided with for the butterfly plate
The seal that 2 sealings coordinate；The seal include front-end and back-end, the front end and the butterfly plate 2 sealing coordinate, it is described after
End is provided with external screw thread, is provided with groove 3 on the valve seat with seal rear end corresponding position, be provided with the groove 3 with
Sealing clamping ring, the seal rear end are provided with the internal thread that the external screw thread is engaged, groove 3 described in the utility model
By the way that in the groove 3 that sealing clamping ring is fixed on the valve seat, the material of the sealing clamping ring is NBR, in other embodiments,
The material of the sealing clamping ring is EPDM or PTFE.Thread locking adhesive is coated with the external screw thread of the seal rear end simultaneously,
Fixed effect of the seal on the valve seat is further increased by setting sealing clamping ring and thread locking adhesive, sealing is prevented
Part comes off in the valve seat.Preferably, the seal front end and the butterfly plate correspondence position are zigzag, accordingly even when close
Sealing weares and teares in use, and the sealing influence on butterfly valve is also smaller.In another preferred embodiment, also sent out including ultrasonic wave
Emitter 4 and ultrasonic receiver, the ultrasonic transmitter 4 are arranged on valve body outside, and the ultrasonic receiver is arranged on
On valve seat at seal, by setting ultrasonic transmitter and ultrasonic receiver, can decline in butterfly valve seal effect
When timely early warning, so as to facilitate user to be changed to seal or searched the sealing problem of butterfly valve presence in time.
Be arranged on seal on valve body by the utility model, the medium punching press that seal is subject to is reduced, so as to alleviate
The abrasion of seal, extends the service life of seal；And seal and butterfly plate corresponding position are set to zigzag, carry
The sealing effectiveness of butterfly valve in the case of sealing part abrasion high.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
