Abstract
The utility model discloses a flange-type single-ball air valve which comprises a valve body and a medium-pressure plate; the medium-pressure plate and the valve body are in sealed connection; a vulcanized sealing piece is coated on the sealing surface of the medium-pressure plate, and the sealing piece and the sealing surface are connected together. Compared with the prior art, the medium-pressure plate of the flange-type single-ball air valve does not need to be processed, the sealing piece can be directly vulcanized onto the medium-pressure plate, so that the processing and assembly are simple and easy, the production efficiency is improved, and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to water supply line valve, and specifically, the utility model relates to a kind of flange-type list ball air valve.
Background technique
Flange-type list ball air valve comprises valve body, valve gap, valve courage, ball float and center platen, between center platen and valve body, is tightly connected.
At present, the center platen of flange-type list ball air valve and the sealing of valve body realize by Sealing, but for fit seal, need to first process center platen, refill and join Sealing to center platen sealing surface, cause course of working complicated, and manufacture cost is high.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of flange-type list ball air valve, makes the processing and assembling of center platen and Sealing simple, reduces manufacture cost.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of flange-type list ball air valve, comprise valve body and center platen, between center platen and valve body, be tightly connected, on the sealing surface of center platen, be coated with sulfuration Sealing being attached thereto and be integral.
Described center platen is ring.
Described sulfuration Sealing is coated on the end face of the inner side surface of described center platen and a side of close described valve body.
Described center platen is bolted on described valve body.
The utility model adopts technique scheme, and compared with prior art, the center platen of this flange-type list ball air valve does not need processing, can directly allow Sealing vulcanize to center platen, make processing and assembling simple, improved manufacturing efficiency, reduced manufacture cost.
Accompanying drawing explanation
Fig. 1 is the half sectional view of flange-type list ball air valve of the present utility model;
