Abstract

A connecting joint of heater water pipes comprises a tubular plug-in body, a locking nut installed on the plug-in body, a locking member inserted between the plug-in body and the locking nut, and a water pipe joint arranged in the front end of the plug-in body. The connecting joint is characterized in that the outer wall of the water pipe joint is conical whose front portion is narrow and rear portion is wide, that the locking member is arranged between the water pipe joint and the locking nut, the inner surface of the locking member is a conical surface which matches with the outer surface of the water pipe joint, and a blocking edge which is blocked between the locking nut and the plug-in body is arranged in the lower part of the locking member. The connecting joint of the utility model has the advantages that the structure is simple, the connection is rapid, the water flow is smooth so that heating effects are not influenced, and scales and impurities are not easy to accumulate to block the water pipe.

Description

The Heater hose jointing
Technical field
The utility model belongs to a kind of pipeline connecting parts, particularly a kind of Heater hose jointing.
Background technique
Existing heating pipeline link comprises that two ends process threaded tubular insert body; Be provided with waterpipe jointing at plug body one end; Said waterpipe jointing is provided with two annular grooves; In each groove, be provided with seal ring, corresponding waterpipe jointing place is connected with locking nut on plug body, between waterpipe jointing and locking nut, is provided with the elasticity locking element.During installation; Earlier, plastic-aluminum interface tube inwall is used the rounding device full circle, in the plastic-aluminum interface tube of then insertion of the waterpipe jointing on plug body rounding being crossed at plastic-aluminum interface tube place suit locking nut and elasticity locking element; The rotation lock nut makes between plug body and the plastic-aluminum pipe through the seal ring sealing.The problem of its existence is: owing on waterpipe jointing, be provided with groove, so waterpipe jointing is the undergauge interface, during water supply, because the waterpipe jointing internal diameter less than the plastic-aluminum bore, causes hot water flow less than normal; After long-time the use, the impurity in incrustation scale and the water is trapped in the undergauge jointing and forms the water route obstruction easily.
Summary of the invention
The purpose of the utility model is to solve the problems referred to above that existing technology exists, provide a kind of simple in structure, connect fast, current are unobstructed, use incrustation scale and impurity to be difficult for piling up for a long time, do not stop up the hot-water heating pipeline connection plug-in unit in water route.
The utility model is achieved in that it comprises the tubular insert body, is installed in locking nut on the plug body, is located at the locking element between plug body and the locking nut; The plug body front end is provided with waterpipe jointing; Its special way is that the outer wall of said waterpipe jointing is beloid taper shape; Between waterpipe jointing and locking nut, be provided with locking element; The conical surface of locking element internal surface for matching with the waterpipe jointing outer wall, the bottom of locking element is provided with the card edge, and said card is along being stuck between locking nut and the plug body.
The utility model has the advantages that: simple in structure, connect quick; Owing to directly contact between waterpipe jointing outer wall and the plastic-aluminum pipe internal surface; And the conical inner surface through locking element is compressing and realize sealing therebetween between waterpipe jointing outer wall and the plastic-aluminum pipe internal surface, and therefore, the waterpipe jointing inwall does not have undergauge; The internal diameter that makes waterpipe jointing is identical with internal diameter with the plastic-aluminum pipe of its cooperation; Guarantee that current are unobstructed, use incrustation scale and impurity to be difficult for piling up for a long time, do not stop up the water route.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Among the figure: 1 one locking elements, 2 one heating installation interfaces, 3 one locking nuts, 4 one plug body, 5 one card edges, 6 one conical surfaces, 7 one waterpipe jointings, 8 one plastic-aluminum pipes.
Embodiment
As shown in Figure 1; The utility model comprises tubular insert body 4, and locking nut 3 is installed on plug body 4, and plug body 4 front ends are provided with waterpipe jointing 7; Said waterpipe jointing 7 outer walls are beloid taper shape; Between waterpipe jointing 7 and locking nut 3, be provided with locking element 1, the conical surface 6 of said locking element 1 internal surface for matching with waterpipe jointing 7 outer walls is provided with card along 5 in locking element 1 bottom; Card edge 5 is stuck between locking nut 3 and the plug body 4, is provided with the heating installation interface 2 that is connected with heating installation in the rear end of plug body 4.
During installation; Earlier, the port inner wall of plastic-aluminum pipe 8 use the rounding device full circle, in plastic-aluminum pipe 8 ports of then the 7 insertion roundings of the waterpipe jointing on the plug body 4 being crossed at the jointing suit locking nut 3 and locking element 1 of plastic-aluminum pipe 8; Rotation lock nut 3; Make locking element 1 compress plastic-aluminum pipe 8, and then realize being connected and sealing between waterpipe jointing 7 and the plastic-aluminum pipe 8 that the heating installation interface 2 with plug body 4 the other ends is connected with radiator then.
