Abstract

The utility model relates to a three-way valve pipe which can be enabled to be directly mutually matched with other various pipeline couplings mainly by separately arranging outside thread parts on the two joint points of the three-way valve pipe without the connecting use of a hollow pipe is not additionally required, achieving the purposes of rapid assembly and pipe arrangement, material saving and manufacturing cost saving.

Description

Three-way valve pipe

The utility model relates to a kind of Three-way valve pipe.

Employed various pipeline mostly is to be screwed together mutually with screw thread in the pipe distribution operation of aspects such as freezing, water power now, a kind of Three-way valve pipe is wherein arranged, it not only can connect the pipeline of three-dimensional, and in Three-way valve pipe, be provided with one and flow to control valve, coming the flow direction of pilot line inner fluid, is a kind of valve pipe quite widely that uses in the refrigerating and air conditioning operation.

Traditional Three-way valve pipe structure can be referring to shown in Fig. 5, this Three-way valve pipe 50 all is formed with internal thread part 54 on three place's joints 52, the hollow tube 44 that can supply all to have external thread part 46 with two ends screws togather mutually, and then by hollow tube 44 in addition the external thread part 46 of end screw togather with other pipeline valve pipes, to finish pipe distribution operation.

Yet traditional Three-way valve pipe 50 structures, because of its pipe joint 52 all is to form internal thread part 54, therefore when it is connected with other pipelines, all need to have the hollow tube 44 of external thread part 46 as media by one, the user is when pipe arrangement, between each valve pipe, all need to be connected with hollow tube 44, so not only can cause user's suitable trouble and inconvenience when the assembling pipe arrangement, need many manpowers of cost and man-hour, more can be because of the too much setting of hollow tube 44, cause the raising of cost of material, and improve whole manufacture cost.

Main purpose of the present utility model is to provide a kind of Three-way valve pipe, can reach to make the Three-way valve pipe assembling quick, with low cost the purpose of increasing economic efficiency.

Secondary objective of the present utility model is to provide a kind of Three-way valve pipe, reaches the purpose that enlarges the Three-way valve pipe using scope.

The technical solution of the utility model is to provide a kind of Three-way valve pipe, in the joint of Three-way valve pipe two ends, is provided with the external thread part that can supply with the direct screw lock of other valve pipes.

Aforesaid Three-way valve pipe, can be provided with one in the joint of Three-way valve pipe and form the female collar, end at the collar is formed with a shoulder, in the collar, be provided with a connecting tube that passes collar shoulder again, be formed with a protuberance that is resisted against collar shoulder inner side edge at an end of connecting tube, and be formed with an outside thread that can be screwed with other valve pipes at the end in addition of connecting tube.

Aforesaid Three-way valve pipe can be provided with a packing ring between connecting tube and Three-way valve pipe joint.

Design features of the present utility model is that it mainly is to be provided with external thread part 14 at two end connectors, 12 places of Three-way valve pipe 10, and the external thread part 14 that can utilize joint 12 directly and other valve pipes 40 combined, need be by the winding (as shown in Figure 5) of a hollow tube 44, flow process of assembling in the time of so not only pipe distribution operation can being simplified and required manpower and man-hour, more can reduce manufacturing and assembly cost because of reducing the number of components; In addition, the utility model can utilize a collar 26 to come the less connecting tube 20 of winding one diameter, matches with the valve pipe 40 of other diameters less than Three-way valve pipe 10 by connecting tube 20, so can suitably enlarge the using scope of Three-way valve pipe 10 again.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.

Brief Description Of Drawings:

Fig. 1 is the perspective exploded view of the utility model when matching with other pipelines.

Fig. 2 is the utility model embodiment's a perspective exploded view.

Fig. 3 is the utility model embodiment's a three-dimensional combination appearance figure.

Fig. 4 is the utility model embodiment's a partial cutaway schematic.

Fig. 5 is the perspective exploded view of traditional Three-way valve pipe when matching with other pipelines.

Referring to Fig. 1, it is the perspective exploded view that the utility model and other valve pipes cooperatively interact, by seeing among the figure, Three-way valve pipe 10 of the present utility model, joint 12 places at its two end all are formed with external thread part 14, then be formed with internal thread part 18 to 16 places, termination that are provided with being vertical with two joints 12, so can utilize external thread part 14 direct being screwed of two joints 12 to be connected with the internal thread part 42 of other valve pipes 40, and also can utilizing its internal thread part 18 and the hollow tube of tool external thread part to be screwed, 16 places, termination are connected, so Three-way valve pipe 10 of the present utility model is when assembly, can directly match with the valve pipe 40 of other tool internal thread parts 42, and do not need as (as shown in Figure 5) as traditional Three-way valve pipe 50, need to be connected by a hollow tube 44, so can simplify the work procedure of pipe arrangement, save material, assembling and manufacture cost.

Referring to Fig. 2,3, they are the utility model embodiment's perspective exploded view and combination appearance figure, by seeing among the figure, respectively be provided with a collar 26 that is formed with internal thread 28 at Three-way valve pipe 10 2 end connectors 12 places, side at this collar 26 is formed with the shoulder 262 of a tool than the minor diameter perforation, in the collar 26, then be equipped with a diameter and perforation connecting tube 20 slightly together, end at this connecting tube 20 is formed with an annular convex 22, in order to be resisted against the inner edge surface of the collar 26 shoulders 262, connecting tube 20 end in addition then is formed with outside thread 24, can be connected so as to being screwed with connecting tube 20 valve pipe 40 slightly together with other diameters, then with the collar 26 screw locks on the external thread part 14 at Three-way valve pipe 10 joints 12 places, make Three-way valve pipe 10 be able to connect mutually with less connecting tube 20 and other valve pipes 40 of diameter, to cooperate different pipe distribution operations, enlarge the using scope of Three-way valve pipe 10; In addition, 12 of joints at connecting tube 20 and Three-way valve pipe 10 can be provided with a packing ring 29, the adaptation when making up to increase each pipeline.
