Abstract
The utility model discloses a pressing fixing type pipe passage accessory, which is mainly composed of a main body. The utility model is characterized in that the interface part of the main body is provided with a bearing groove. The utility model is reasonable in structure; when a pipe fitting which is subjected to external force is connected with pipe passage accessories, such as a filament joint, a three-way valve, an angle head, etc., the pipe fitting is embedded into compression expansion generated by the bearing groove, the cross section of which is trapezoidal, to make the bearing groove closely attached to the pipe fitting, and the larger the pressure, the better the anti-leakage effect is.
Description
Technical field:
The utility model relates to a kind of pipeline fittings, particularly relates in a kind of fluid delivery system, is used for the pipeline fittings of connecting tube.
Background technique:
It is an integrated technology that pipeline connects, and in modern industry and various fields in science and technology, has purposes and effect widely.At present, the equipment leakage phenomenon in the fields such as whole world machinery, chemical industry is quite universal, is long-term chronic disease, not only causes the waste of the energy and material, and jeopardizes personal safety, influences quality of product.The main cause that produces this situation is the pipeline fittings unreasonable structure, poor sealing performance, mostly be with the leak-proof manner of pipeline junction and fill out the pad sealing material or end face compresses sealing, this kind mode not only material is wasteful, the installation requirement height, and implement loaded down with trivial details relatively, under high temperature, high pressure and temperature variation state, the permanent stability of its sealing is low, needs frequent Maintenance and Repair, and is very inconvenient.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, at good high temperature resistant, the high pressure of high temperature, high pressure lower seal performance, press fixing type pipeline fittings.The technological scheme that its technical problem that solves the utility model adopts is, a kind of press fixing type pipeline fittings mainly is made up of body, and its characteristics are: the jointing of body offers a holding groove.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is rational in infrastructure, be skillfully constructed, when the pipe fitting that is subjected to the external force effect was connected with pipeline fittingses such as wire connection head, threeway, elbows, pipe fitting embedded cross section and is the trapezoidal pressure that holding groove produced and expands itself and pipe fitting are fitted tightly, and pressure is big more, leak preventing effect is good more, the tool promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Structural representation when Fig. 2 joins for the utility model and a pipe fitting.
Embodiment:
Referring to Fig. 1, a kind of high temperature resistant, high pressure, press fixing type pipeline fittings mainly are made up of body 40, and the jointing 10 of body 40 offers a holding groove 11, and the cross section of this groove is trapezoidal.Referring to Fig. 2, pipe fitting 20 makes both fastening by a gland nut 30 after embedding in the holding groove 11.When the pipe fitting 20 that is subjected to the external force effect embeds cross sections when being trapezoidal holding groove 11, the pressure that the notch end produces expands itself and pipe fitting 20 is fitted tightly, and sealing effect has been guaranteed in gland nut 30 fastening effects in addition.
Claims (2)
1, a kind of press fixing type pipeline fittings mainly is made up of body, it is characterized in that: the jointing of body offers a holding groove.
2, by the described a kind of press fixing type pipeline fittings of claim 1, it is characterized in that: the cross section of described holding groove is trapezoidal.
