Abstract
A kind of two-way hard seal butterfly valve with elastic seat, comprise valve body, valve rod, butterfly plate, described valve rod is fixedly connected with butterfly plate through valve body, valve body is fixedly connected with valve seat, valve seat and butterfly plate fitted seal, valve seat is made up of C shape coil support and C shape eyelet, C shape coil support is C shape structure, to be fixed on valve body by cold setting and and form cavity between valve body, C shape eyelet is arranged in cavity, and have part surface to contact with butterfly plate sealing surface to form sealing pair, the opening end of C shape eyelet and the opening end of C shape coil support are oppositely arranged, the end face of remaining silent of C shape coil support at least has 1 through hole.The beneficial effects of the utility model are: the structure adopting C shape eyelet, can realize two way sealed, and itself has elastic characteristic, can auto-compensation wear extent, ensure the sealability of valve.
Description
Art
The utility model relates to a kind of valve, particularly relates to a kind of two way sealed hard seal butterfly valve.
Background technique
Current existing hard seal butterfly valve, valve seat is all pile-up welding hard alloy usually, easily leaks during use, and can not realize two way sealed, also cannot auto-compensation after Long-Time Service wearing and tearing, and maintenance cost is higher.
Model utility content
In order to overcome the above-mentioned shortcoming of existing hard seal butterfly valve, the utility model provides a kind of and realizes two way sealed and can the hard seal butterfly valve of auto-compensation.
The utility model solves the technological scheme that its technical problem adopts, a kind of two-way hard seal butterfly valve with elastic seat, comprise valve body, valve rod, butterfly plate, described valve rod is fixedly connected with butterfly plate through valve body, valve body is fixedly connected with valve seat, valve seat and butterfly plate fitted seal, valve seat is made up of C shape coil support and C shape eyelet, C shape coil support is C shape structure, to be fixed on valve body by cold setting and and form cavity between valve body, C shape eyelet is arranged in cavity, and have part surface to contact with butterfly plate sealing surface to form sealing pair, the opening end of C shape eyelet and the opening end of C shape coil support are oppositely arranged, the end face of remaining silent of C shape coil support at least has 1 through hole.
Preferred version is, C shape eyelet is through Wear-resistant Treatment.
The beneficial effects of the utility model are:
(1) structure of C shape eyelet is adopted, when medium positive flow is out-of-date, because C shape eyelet has certain elasticity, realize forward seal, when medium flows counterflow through, due to C shape coil support being at least provided with a through hole with butterfly plate close contact, after medium enters C shape eyelet through through hole, make C shape enclose accumulation of energy, thus it is more tight that C type eyelet is contacted with butterfly plate, realize oppositely sealing.
(2) when after Long-Time Service, C shape eyelet weares and teares, due to the elastic characteristic of itself, can auto-compensation wear extent, and ensure the sealability of valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment;
Fig. 2 is that in Fig. 1, sending out of I place is schemed greatly.
In figure: 1. valve body; 2. valve seat; 3. butterfly plate; 4. valve rod; 5. C shape coil support; 6. C shape eyelet; 7. cavity 8. butterfly plate sealing surface; 9. through hole.
Embodiment
As Fig. 1, shown in 2, a kind of two-way hard seal butterfly valve with elastic seat, comprise valve body 1, valve rod 4, butterfly plate 3, described valve rod 4 is fixedly connected with butterfly plate 3 through valve body 1, valve body 1 is fixedly connected with valve seat 2, valve seat 2 and butterfly plate 3 fitted seal, valve seat 2 is made up of C shape coil support 5 and C shape eyelet 6, C shape coil support 5 is C shape structure, to be fixed on valve body 1 by cold setting and and form cavity 7 between valve body 1, C shape eyelet 6 is arranged in cavity 7, and have part surface to contact with butterfly plate sealing surface 8 to form sealing pair, the opening end of C shape eyelet 6 and the opening end of C shape coil support 5 are oppositely arranged, the end face of remaining silent of C shape coil support 5 at least has 1 through hole 9, preferred version is, C shape eyelet 6 is through Wear-resistant Treatment, wear extent can be reduced, long service life.
Claims (2)
1. one kind has the two-way hard seal butterfly valve of elastic seat, comprise valve body, valve rod, butterfly plate, described valve rod is fixedly connected with butterfly plate through valve body, described valve body is fixedly connected with valve seat, valve seat and butterfly plate fitted seal, it is characterized in that: described valve seat is made up of C shape coil support and C shape eyelet, described C shape coil support is C shape structure, to be fixed on valve body by cold setting and and form cavity between valve body, described C shape eyelet is arranged in cavity, and have part surface to contact with butterfly plate sealing surface to form sealing pair, the opening end of described C shape eyelet and the opening end of C shape coil support are oppositely arranged, the end face of remaining silent of described C shape coil support at least has 1 through hole.
2. the two-way hard seal butterfly valve with elastic seat according to claim 1, is characterized in that: described C shape eyelet is through Wear-resistant Treatment.
