Abstract

The utility model relates to a z-pipe connecting member which is used for a water-supply pipeline and a gas pipeline when the water-supply pipeline and the gas pipeline are required to break and bend back and forth for installing, in particular that the utility model is used for the interconnection of a heating pipeline and a radiator when the heating pipeline and the radiator are required to bend back and forth for installing. A z-shaped main body member (1) is a malleable cast iron or gray iron model. Two end openings of the main body member are not on a shaft line. The angle of a z-shaped pipe is equal to or smaller than 90 DEG. The long thread side of the z-shaped main body member (1) is provided with an inner connecting head (2) and a locking nut (3) which are connected and formed integration. The z-pipe connecting member is divided into an inner thread, an outer thread, an inner-outer thread and a long thread which form the movable type z-pipe connecting member.

Description

Z-pipe connecting member

The utility model relates to a kind of installation that is used for indoor Pipeline, gas pipe line, particularly interconnects need carry out bending back and forth and install the time second shape pipe joint of use at hot duct and radiator.

At present in the installation of carrying out indoor Pipeline, gas pipe line, particularly when hot duct and radiator interconnect, the installing engineering of some radiator need be used second shape pipe joint, now the second shape pipe joint that uses is with manual the bending of steel pipe and forms, when the second shape pipe joint that bends more than 20 millimeters, because the technical difficulty that requires is bigger, and up-to-standard rate is not high, when carrying out being connected of hot duct and radiator, also to be equipped with simultaneously the union of all size, be used for finishing the work that is connected of hot duct and radiator.So both increase the workload and the difficulty of installment work, wasted pipe joint again.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art, is intended to provide a kind of operation and difficulty that reduces pipe fitting, saves material the second shape pipe joint of increasing work efficiency.

The purpose of this utility model can reach by following measure.

Second shape pipe joint described in the utility model, can be by malleable cast iron or gray cast iron moulding, the second shape main component of all size, two port is not on a shaft axis, the angle of second shape pipe can be equal to or less than 90 degree, can be divided into internal thread, outer silk, inside and outside silk second shape pipe joint, both two of second shape tube body spare ports were that internal thread or outside thread or a port are that another port of internal thread is an outside thread, long filament shape loose joint formula second shape pipe joint, a port is internal thread or outside thread, and another port is connected as one by second shape tube body spare (long filament side) and spigot and locking nut.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Second shape pipe joint described in the utility model, form by second shape main component (1), spigot (2) and locking nut (3), its second shape main component (1) is by malleable cast iron or gray cast iron moulding, two ports are not on same shaft axis, and the angle of second shape pipe is equal to or less than 90 degree.Second shape pipe joint described in the utility model is divided into internal thread, outer silk, inside and outside silk second shape pipe joint and internal thread long filament shape, outside thread long filament shape loose joint formula second shape pipe joint, with reference to accompanying drawing 4,5, second shape main component (1) is become one with spigot (2) and locking nut (3) by internal and external threads.

Fig. 1 is the profile and the part sectioned view of inside and outside silk second shape pipe joint described in the utility model, and port of its second shape pipe joint is an internal thread, and another port is an outside thread.

Fig. 2 is the profile and the part sectioned view of outer silk second shape pipe joint described in the utility model, and two ports of its second shape pipe joint are outside thread.

Fig. 3 is the profile of internal thread second shape pipe joint described in the utility model and partly cuts open figure that two ports of its second shape pipe joint are internal thread.

Fig. 4 is the profile of internal thread long filament shape loose joint formula second shape pipe joint described in the utility model and partly cuts open figure, long filament side one end of its second shape main component (1) is connected with locking nut (3) with spigot (2), and the another port is an internal thread.

Fig. 5 is the profile of outside thread long filament shape loose joint formula second shape pipe joint described in the utility model and partly cuts open figure, and long filament side one end of its second shape main component (1) is connected with locking nut (3) with spigot (2), and the another port is an outside thread.

Fig. 6 and Fig. 7 be second shape pipe joint described in the utility model spigot (2) the plane and partly cut open figure.

Fig. 8 and Fig. 9 be second shape pipe joint described in the utility model locking nut (3) the plane and partly cut open figure.

When carrying out the installation of indoor Pipeline, gas pipe line, hot duct, when both the pipeline that need carry out bending back and forth of interconnecting between pipeline and the pipeline is installed, use the internal thread in the second shape pipe joint described in the utility model, outer silk, inside and outside silk second shape pipe joint just can finish.Carrying out pipeline that interconnecting between hot duct and the radiator need carry out bending back and forth when installing, can use internal thread long filament shape described in the utility model or outside thread long filament shape loose joint formula second shape pipe joint.During operation, as radiator is outer filate, available internal thread long filament shape loose joint formula second shape pipe joint, earlier the port of internal thread one end and the outside thread of radiator are interconnected, spigot (2) with internal thread long filament shape loose joint formula second shape pipe joint docks with the outside thread of heating pad pipe again, bite spigot (2) to counterclockwise rotation with box spanner, at this moment the internal thread of spigot (2) is connected with the outside thread of hot duct gradually, screw locking nut (3) subsequently, give spigot (2) fastening.When being interior filate as radiator, available outside thread long filament shape loose joint formula second shape pipe joint interconnects.

Second shape pipe joint described in the utility model is compared with traditional similar link, can guarantee the quality of the ellipse garden rate of bend pipe, and fitting operation is easy, reduces labor intensity, and saves material, and reduces cost.
