Abstract
The utility model discloses and a kind ofly connect wall-hung boiler loose joint ball valve that is reliable, good sealing effect.It comprises valve body, is located at the water outlet of valve body one end, described water outlet end is provided with articulating joint, described articulating joint comprises metal connecting piece and plastic fastening, described metal connecting piece periphery is provided with dovetail groove, described plastic fastening inner circumferential is provided with dovetail flange, and the dovetail groove of described metal connecting piece periphery and the dovetail flange of plastic fastening inner circumferential engage each other.The utility model is applicable to the ball valve with loose joint on wall-hung boiler.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of ball valve being applicable to loose joint connection on wall-hung boiler.
Background technique
Ball valve is gained the name because its closure member adopts spheroid, its working principle is that spheroid reaches unlatching around valve body center line do rotation, closes object, ball valve is mainly used to the flow direction cutting off, distribute and change medium in pipeline, it only just can need close tight by the operation of 90-degree rotation and very little rotatory force, and it uses usually used as switch, cut-off valve.Also ball valve can be used in wall-hung boiler, metallic material is originally all adopted to make, because tradition is for thermal recovery metal tube, thus there is thermal conductivity strong, the defect such as perishable, have a strong impact on heating efficiency and the working life of heating system, there is energy consumption large simultaneously, utilization ratio is low waits deficiency, so gradually substitute by plastic pipe, and plastic pipe cannot be connected with metal valve, the metal insert with plastic melting fitting can only be adopted directly could to be connected with metal valve, but due to metal and plastics, to there is expansion coefficient different, in use, easily produce between metal insert with plastic melting fitting be connected insecure, and due to sealing configuration simple, cause connecting the aging generation seepage in sealing position, impact is normal to be used.
Model utility content
The technical problems to be solved in the utility model is to provide and a kind ofly connects wall-hung boiler loose joint ball valve that is reliable, good sealing effect.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises valve body, is located at the water outlet of valve body one end, described water outlet end is provided with articulating joint, described articulating joint comprises metal connecting piece and plastic fastening, described metal connecting piece periphery is provided with dovetail groove, described plastic fastening inner circumferential is provided with dovetail flange, and the dovetail groove of described metal connecting piece periphery and the dovetail flange of plastic fastening inner circumferential engage each other.
As preferably, described metal connecting piece periphery is provided with seal groove, is provided with seal ring in described seal groove.
As preferably, described metal connecting piece periphery is provided with bulge loop, and described bulge loop end face is provided with seal ring.
The utility model compared with prior art, has following obvious advantage and beneficial effect:
1, connect reliably.Because metal connecting piece in the utility model and plastic fastening adopt mutual embedded structure, thus improve the reliability of connection.
2, good sealing effect.Because articulating joint in the utility model and valve body adopt double sealing structure, effectively improve sealing effect.
