Abstract
The utility model provides a sealed vice structure of butterfly valve sealed firmly, includes valve body, valve rod, butterfly plate, the valve rod runs through inside the valve body, fixedly connected with dish board on the valve rod, dish flange reason is last to have the butterfly plate sealing washer through the clamping ring crimping, and is formed with the pretension space between clamping ring and the dish board, valve seat insert in the valve body connects through the build -up welding. The clamping ring compress tightly butterfly valve sealing washer and butterfly plate through the screw. The dish board through promoting fixed connection. The beneficial effect of the utility model: the utility model provides a sealed vice structure of butterfly valve sealed firmly sealing performance is good, and the valve plate is high with disk seat faying face superficial hardness, and the wearability is good.
Description
Technical field
The utility model relates to valve technology field, particularly a kind of hard seal butterfly valve sealing pair structure.
Background technique
It is reliable not that valve sealing structure under prior art designs, and the increase along with service time easily causes valve to leak, and causes the generation of the wasting of resources or harm.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of hard seal butterfly valve sealing pair structure.
To achieve these goals, the utility model solves the technological scheme that its technical problem adopts: a kind of hard seal butterfly valve sealing pair structure, comprise valve body, valve rod, butterfly plate, described valve rod is through valve inner, described valve rod is fixedly connected with dish plate, described dish panel edges is crimped with butterfly plate seal ring by trim ring, and is formed with pretension space between trim ring and dish plate, the valve seat insert in described valve body is connected by built-up welding.
Furtherly, butterfly valve seal circle and butterfly plate are compressed by screw by described trim ring.
Again furtherly, described dish plate is fixedly connected with by distribution.
The beneficial effects of the utility model: this hard seal butterfly valve sealing pair sealing structure performance that the utility model provides is good, valve plate and valve seat junction plane surface hardness high, wear resistance is good.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is the partial enlargement structural representation of Fig. 1.
