Description

The utility model relates to pipe connections and can be used, for example, when a pipeline (gas, oil, water) is inserted into the line on the heads and covers of wells.

Couplings from IDRO GAS ENG are known. EUROPA, Italy, mod. TREPI, INOXGIS, ETERNO, consisting of two or three segments, used for connecting pipes (see prospectus of IDRO GAS Engineering Europa, Italy, bg, bd). Couplings from Viking Johnson, Great Britain, containing a body with a bell and a flange, a sliding flange with a seal chamber, in which a sealing element and fasteners are placed, are also known (see Prospectus from Viking Johnson, Netherlands, Great Britain, used, .).

The closest analogue to the claimed coupling is the coupling (see https://yandex.ru/video/search?text=%D0%BC%D1%83%D1%84%D1%82%D0%B0%20%D1% 81% D0% BE% D0% B5% D0% B4% D0% B8% D0% BD% D0% B8% D1% 82% D0% B5% D0% BB% D1% 8C% D0% BD% D0% B0% D1% 8F% 20% D0% B4% D0% BB% D1% 8F% 20% D1% 82% D1% 80% D1% 83% D0% B1 & path = wizard & noreask = 1 & filmId = 12718440038535658895- prototype) containing a housing with a working and sealing parts, a nut screwed onto the housing from its end.

The disadvantage of these analogues, including the prototype, is that they are not reliable enough and convenient to use, especially on the heads and covers, where the pipe is cut and fixed rigidly from the bottom of the head to the coupling. To reduce the immersion depth of the pump, it is necessary to remove (unscrew) the head or cover of the well from the casing, then unwind this sleeve and cut the pipe, and then screw (attach) the head or cover onto the casing again and firmly fix the feed pipe. If it is necessary to increase the immersion depth of the pump - then this is even more difficult - you must again remove the head (cover) from the casing and grow the pipe with a sleeve or brazing, then put the head (cover) back on the casing. All these connections remain under the head (cover) inside the pipe without the possibility of subsequent tightness control. This can lead to a breakdown of the pump automation and the pump itself, as all this is done on weight, with great physical effort (the weight of the pump and equipment can reach up to 200 kg). The pipe joints and couplings remain under the borehole cover and this is bad, they always put the whole pipe in such places without any connections (to avoid possible leaks and leaks).

The task in creating the coupling was the development of a product for connecting pipes, incl. and on the heads and covers of the wells, and the technical result is an increase in reliability and ease of use.

The specified technical result is achieved by using a pipe coupling containing a housing with a working and sealing parts, a nut screwing onto the housing from its end, in which, according to a utility model, the inner diameter of the coupling housing, along its entire length, is made not less than the outer diameter inserted into the pipe coupling, the inner diameter of the working part of the coupling equal to the outer diameter of the pipe inserted into the coupling, in the sealing part of the body there is a sealing ring with a spacer insert and a split insert a, his shoulder cooperating with a nut and a nut on the opposite end of the housing to the mounting part, is threaded down to the existing shoulder thereon with grooves

The coupling is illustrated in the drawings of FIG. 1-3, on which:

FIG. 1 - coupling for pipes (cut),

FIG. 2 - coupling for pipes (general view),

FIG. 3 - coupling for pipes (section), where:

D is the inner diameter of the coupling body,

1 - the working part of the housing,

2 - sealing part of the housing,

3 - mounting part of the housing,

4 - nut

5 - a sealing ring,

6 - spacer insert

7 - split insert,

8 - collar split insert,

9 - thread

10 - shoulder of the body with grooves,

11 - grooves in the shoulder of the housing.

The pipe coupling contains a housing with a working 1, sealing 2 and fixing 3 parts, a nut 4 screwed onto the sealing part of the housing 2 from its end, and the inner diameter of the coupling body, along its entire length, is made not less than the outer diameter of the pipe inserted into the coupling (the pipe in Fig. 1-3 is not shown), and the inner diameter D of the working part of the coupling body 1 is equal to the outer diameter of the pipe inserted into the coupling, in the sealing part of the housing 2 there is a sealing ring 5 with a spacer insert 6 and a split insert 7, with its shoulder 8 interacting with aykoy 4, and at the opposite end from the nut body 4, on the mounting part 3, has a thread 9, up to the shoulder formed on the housing 10 with the slots 11.

Before starting work, the coupling body by means of a thread 9, using a shoulder 10 with grooves 11, is mounted on the head or cover of the well (not shown in Figs. 1–3). The coupling is assembled, and without tightening the nuts 4, a pipe with an external diameter D is inserted into it of the required length, which is connected to the pump and other necessary equipment. Then the pipe is sealed by tightening the nut 4. At the same time, the spacer insert 6 presses on the sealing ring 5, and in turn with its collar 8, the split insert 7, which, compressing, gives mechanical rigidity to the connection.

If it is necessary to change the immersion depth of the pump, the nut 4 is unscrewed, the pipe mount is loosened, and it easily moves along the inner diameter D of the coupling in one direction or another, while remaining solid (without connections), and then sealed in the same way.

Thus, using the claimed technical solution, the claimed technical result is achieved - improving the reliability of operation and ease of operation.
