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

A kind of flange-type list ball air valve
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;
Mark in above-mentioned figure is: 1, valve body; 2, ball float; 3, valve courage; 4, center platen; 5, valve gap; 6, sulfuration Sealing.
Embodiment
Be illustrated in figure 1 a kind of flange-type list ball air valve of the present utility model, comprise valve body 1, ball float 2, valve courage 3, valve gap 5 and center platen 4, ball float 2 is arranged in valve courage 3, valve courage 3 is arranged in valve body 1, center platen 4 is positioned at the end of valve courage 3 and valve courage 3 is played to the effect of stop bit, valve gap 5 covers center platen 4 in valve body 1 outside, and valve gap 5 and valve body 1 are also bolted.Center platen 4 is bolted on valve body 1, between center platen 4 and valve body 1 and for being tightly connected.On the sealing surface of the center platen 4 of this valve, be coated with sulfuration Sealing 6 and be attached thereto and be integral.
As shown in Figure 1, this center platen 4 is ring.Sulfuration Sealing 6 is coated on the inner side surface and the end face near a side of valve body 1 of center platen 4, and sulfuration Sealing 6 is whole is the circular ring of convex shape for longitudinal section.
The material of the valve body 1 of this valve, valve courage 3, center platen 4 and valve gap 5 is cast iron, and the material of ball float 2 is ABS, and the material of sulfuration Sealing 6 is rubber.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
