Abstract

The utility model provides a pipeline connector and a corresponding combined structure thereof, wherein the pipeline connector is provided with at least one male screw section; at least one corresponding combined piece opposite to the male screw section of the pipeline connector is provided with a screw hole to form a screw-connection state. The utility model is characterized in that the front end of the male screw section of the pipeline connector is sheathed with a first O-shaped ring, the tail end of the male screw section is connected with an annular ring part on which a second O-shaped ring is arranged, and the corresponding combined piece corresponding to the annular ring part is provided with an inner edge part tightly contacted with the second O-shaped ring so as to block leakage caused by pressure impact in pipelines.

Description

Pipeline connecting parts and corresponding composite construction thereof

Technical field

The utility model relates to a kind of pipeline connecting parts technology, particularly relates to a kind of leakproof of strengthening pipeline, to block pipeline connecting parts and the corresponding composite construction thereof that the seepage situation takes place.

Background technique

Required water in our daily life, all need to reach the facility of water by the configuration of pipeline, though and this pipeline can provide people to take the convenience of water, part often has the situation of seepage to take place but pipeline is connected with other link, the end of pipeline especially, the compression shock that is brought because of the hydraulic pressure shakiness, the main cause of seepage takes place especially, and in order to prevent the generation of aforementioned percolating water, the mode that adopts has following two kinds at present, and division is as follows:

One, before pipe arrangement, on the external thread section of link, twine a few waterstops (Tape Seal), treat with the space between the elimination screw thread, to reach the purpose of leakage proof with after corresponding link makes up; But this kind mode not only leakproof weak effect and take a lot of work outside, this waterstop and can't reuse (or secondary construction), and cause the waste of material.

Two, as shown in Figure 1, before pipe arrangement, at the solid O shape ring of the end of link A external thread section cover A1, after utilizing this O shape ring A1 and corresponding link making up, with the generation of obstruct seepage; Yet, finding that on practice this O shape ring A1 often is exposed to the outer or peritreme place, hole of corresponding link, and in case when meeting the impact of hydraulic pressure, this O shape ring A1 promptly can be toward direction slippage outside the hole one apart from (be commonly called as and move back tooth), and the liquid in the pipeline is leaked out by this place.

Summary of the invention

The purpose of this utility model is to improve part not to the utmost in view of prior art still has, and it is further improved, thereby a kind of pipeline connecting parts and corresponding composite construction thereof are provided, to block the facts that seepage takes place in the pipeline.

The purpose of this utility model realizes by following technical proposals, a kind of pipeline connecting parts provided by the utility model and corresponding composite construction thereof, and wherein this pipeline connecting parts is provided with a male threaded section at least; At least one corresponding assembly parts is established a tapped hole with respect to the male threaded section place of this pipeline connecting parts, can form the state of screwing togather, and of the present utility model being characterised in that: the front end sleeve of the male threaded section of this pipeline connecting parts is provided with O shape ring, the end of this male threaded section is equipped with a loop portions again, be arranged with the 2nd O shape ring on it, and should corresponding this loop portions of correspondence assembly parts be provided with one with the mutually closely connected inner edge portion of the 2nd O shape ring, to block the seepage that compression shock was caused in the pipeline.

Further specify content of the present utility model, feature and effect by the following examples and in conjunction with the accompanying drawings, make it possible to the utility model had further be well understood to.

Primary clustering symbol description: 1 pipeline connecting parts; 11 male threaded section; 12 the one O shapes ring; 13 loop portions; 131 grooves; 14 the 2nd O shapes ring; 2 corresponding assembly parties; 21 tapped holes; 22 inner edge portion.

Embodiment

See also Fig. 2,3, and cooperate shown in Figure 4ly, the utility model provides a kind of pipeline connecting parts and corresponding composite construction thereof, and it mainly comprises:

One pipeline connecting parts 1;

The outer rim of this pipeline connecting parts 1 is provided with a male threaded section 11, and the front end sleeve of this male threaded section 11 is provided with O shape ring 12; The end of this male threaded section 11 is equipped with a loop portions 13 again, the diameter dimension of these loop portions 13 outside dimensions and this male threaded section 11 is basic identical, this loop portions 13 is equipped with a groove 131 again, and intrinsic the 2nd O shape ring 14 of cover on this groove 131, and the 2nd O shape ring 14 exceeds trough rim one distance of this groove 131.

One corresponding assembly parts 2;

Corresponding assembly parts 2 is established a tapped hole 21 with respect to male threaded section 11 places of this pipeline connecting parts 1, screw togather state with formation, the position of loop portions 13 that again should correspondence assembly parts 2 corresponding these pipeline connecting parts 1 is provided with inner edge portion 22 mutually closely connected with the 2nd O shape ring 14, and when the corresponding assembly parts with this of this pipeline connecting parts 12 is combined, can encircle 14 configuration by O shape ring 12 and the 2nd O shape, and block the seepage that compression shock caused in the pipeline fully; In addition, this correspondence assembly parts 2 can be any pipe joint or the accessory of other pipeline such as chassis of drinking machine etc. with female thread.

See also Fig. 3 to shown in Figure 4, it is should correspondence assembly parts 2 matched combined L type pipeline connecting parts in the utility model and the embodiment of T type pipeline connecting parts; Seeing also again that this is shown in Figure 5, is the embodiment of the corresponding assembly parts of L type pipeline connecting parts matched combined Nipple type in the utility model.

Continue to see also shown in Figure 6, it is that the corresponding assembly parts 2 with this of this pipeline connecting parts 1 is used in the enforcement aspect of forming on the drinking machine as shown in the figure.

The effect that the utility model construction features are produced

One, the 2nd set O shape is encircled in the structure of the present utility model, is closely to fit on the inner edge portion of this correspondence assembly parts, thereby can bears the compression shock that the hydraulic pressure shakiness is brought, and block leaking outside of liquid.

Two, the O shape ring in the utility model structure is in case take place aging or damaged, and when causing liquid in the pipeline to leak out by an O shape ring place, can be by setting by the 2nd O shape ring, and form secondary obstruct, make this liquid that leaks out be denial in the utility model fully, and the facts such as ne-leakage take place.

In sum, the disclosed technological means of the utility model really can reach and cause its intended purposes and effect, has solved the variety of problems of conventional devices and shortcoming simultaneously and has long-range progressive.

The above, it only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, promptly all equivalences of doing according to the utility model claim and creation description change and modify, and all should still belong in the scope that the utility model patent contains.
