Abstract

The utility model relates to a device for replacing pipe fittings, which is a pipe fitting replacing device, and comprises a transition pipe and a standard pipe, wherein one end of the transition pipe is provided with a standard pipe mouth, and the other end thereof is provided with a transition pipe mouth the inner diameter of which is equal to that of the transition pipe; the inner diameter of the transition pipe is larger than the inner diameter of the standard pipe mouth; the inner wall of the transition pipe at one side of the transition pipe mouth is provided with at least one lug; a seal ring and a bushing are sheathed on the standard pipe in sequence; the inner end of the standard pipe penetrates through the transition pipe mouth, enters in the transition pipe, and moves along the axis of the transition pipe; and the standard pipe props the seal ring against the lug through the bushing and is fixedly arranged together with the transition pipe. The pipe fitting replacing device has simple structure and convenient use; as an action space is arranged, the pipes do not need to be replaced, or the pipes do not need to be threaded, therefore, the pipe fittings can be conveniently installed, and potential safety hazards are eliminated.

Description

Pipe fitting is changing device more

Technical field

The utility model relates to a kind of device of retubing, and especially a kind of pipe fitting is changing device more.

Background technique

When hot-water heating parts such as replacing tap water or heating installation, when the hot-water heating parts with after pipe is fixedlyed connected, because the silk mouthful size of hot-water heating parts is in that to add man-hour wrong poor, with regard to the other end that has pipe and several millimeters to several centimetres of other connection pipe fitting differences and the problem that does not connect, so just need retube again or give pipe mantle fiber mouth, also have error with regard to time-consuming taking a lot of work like this; Connect by force besides, have serious potential safety hazard like this.

Summary of the invention

The utility model provides more changing device of a kind of pipe fitting, has overcome the deficiency of above-mentioned prior art, and it can solve owing to the pipe fitting error causes pipe fitting and be difficult for the problem that connects.

The technical solution of the utility model is achieved like this: a kind of pipe fitting is changing device more, comprise transition body and standard pipe, end at the transition body has the standard mouth of pipe, the other end at the transition body has the transition mouth of pipe identical with the transition internal diameter of tube body, the internal diameter of the internal diameter overgauge mouth of pipe of transition body, on the inwall of the transition body of the transition mouth of pipe one side, have and be no less than one projection, on standard pipe, be set with seal ring and bushing successively, the inner of standard pipe is passed the transition mouth of pipe and projection and is entered in the transition body and can move along the axis of transition body, and standard pipe withstands on seal ring on the projection and with the transition body by bushing and is fixedly installed togather.

Above-mentioned projection is the annular lug along transition inboard wall of tube body circumference.

Between above-mentioned seal ring and the bushing sealing gland is arranged.

Above-mentioned seal ring adopts the O RunddichtringO.

The utility model is simple in structure, and is easy to use, owing to leave activity space, do not need to retube again or gives pipe mantle fiber mouth, therefore pipe fitting can easily be installed, and also eliminated potential safety hazard.

Description of drawings

Fig. 1 looks sectional view for master of the present utility model.

Fig. 2 looks side view for the right side of Fig. 1.

Coding among the figure is respectively: 1 is the transition body, and 2 is standard pipe, and 3 is the standard mouth of pipe, and 4 is sealing gland, and 5 is projection, and 6 is seal ring, and 7 are bushing.

Embodiment

As Fig. 1, shown in 2, a kind of pipe fitting is changing device more, comprise transition body 1 and standard pipe 2, end at transition body 1 has the standard mouth of pipe 3, the other end at transition body 1 has the transition mouth of pipe identical with transition body 1 internal diameter, the internal diameter of the internal diameter overgauge mouth of pipe 3 of transition body 1, on the inwall of the transition body 1 of the transition mouth of pipe one side, the projection 5 that is no less than is arranged, on standard pipe 2, be set with seal ring 6 and bushing 7 successively, the inner of standard pipe 2 is passed the transition mouth of pipe and projection 5 and is entered in the transition body 1 and can move along the axis of transition body 1, and standard pipe 2 withstands on seal ring 6 on the projection 5 and with transition body 1 by bushing 7 and is fixedly installed togather.

As shown in Figure 1, in order to gain in strength, projection 5 is the annular lugs along transition inboard wall of tube body circumference.

As shown in Figure 1, in order to improve leak resistance, between seal ring 6 and bushing 7, sealing gland 4 can be arranged.

As shown in Figure 1, seal ring 6 adopts the O RunddichtringO.

When mounted, at first the inner of standard pipe 2 is put in the transition body 1, again the standard mouth of pipe 3 is connected with standard body or other standard fittings by screw thread, outer end with standard pipe 2 is connected with valve or other standard fittings then, at last with seal ring 6, sealing gland 4 is put in the transition body 1, at last bushing 7 is tightened.When changing valve or other standard fittings, earlier pine is unloaded in bushing 7, take out bushing 7, sealing gland 4 then, seal ring 6, because the inner of standard pipe 2 can be moved in transition body 1, so very easily the other end of standard pipe 2 is unloaded down from valve or other standard fittings, after more finishing changing valve or other standard fittings, the outer end of standard pipe 2 and valve or other standard fittings are installed together, again with seal ring 6, sealing gland 4 is put in the transition body 1, at last bushing 7 is tightened water-tight getting final product.

Claims (5)

1, a kind of pipe fitting is changing device more, it is characterized in that comprising transition body and standard pipe, end at the transition body has the standard mouth of pipe, the other end at the transition body has the transition mouth of pipe identical with the transition internal diameter of tube body, the internal diameter of the internal diameter overgauge mouth of pipe of transition body, on the inwall of the transition body of the transition mouth of pipe one side, have and be no less than one projection, on standard pipe, be set with seal ring and bushing successively, the inner of standard pipe is passed the transition mouth of pipe and projection and is entered in the transition body and can move along the axis of transition body, and standard pipe withstands on seal ring on the projection and with the transition body by bushing and is fixedly installed togather.

2, pipe fitting according to claim 1 changing device more is characterized in that projection is the annular lug along transition inboard wall of tube body circumference.
