Description
Technical field:
The utility model relates to the delivery pipe field, specifically is a kind of conveying liquid, gas connection pipe external member, and the material of connecting tube external member can be metal, alloy or nonmetal.
Background technique:
Connect the water supply that is connected of tubing, heat supply, many-sided field extensive use such as air feed, aspect the interconnection technique of pipe, all the time rest on: open silk or fluting in the end of pipe fitting, open corresponding silk or groove again in the end of another pipe fitting, by two pipe fittings the silk with the groove phase interlock finish being connected of pipe fitting, so just there are a lot of deficiencys, connecting back intensity such as pipe fitting reduces, the production technology relative complex, install inconvenient, cost is high relatively, in order to overcome the problems referred to above, also the someone adopts radially to swell in the tubing end and forms a circle bulge loop, add pipe cap behind the bulge loop, advance and the screw thread of the link pressure zone that interlocks moves hollow tube and solves with being connected of link with pipe cap, but also there is shortcoming in this method, enclose bulge loop than all high on technology and cost at end protuberance one in end protuberance some spots projection, effect is better in use through facts have proved the some some projectioies of protuberance, moreover also there is shortcoming with the matching used seal ring of hollow tube in actual use, conventional used seal ring shape is not an external conical shape, be unfavorable for strengthening the sealing that pipe fitting connects like this, conventional link (straight tube, threeway or four-way etc.) an end and the shape of the contacted recess of seal ring also be unfavorable for strengthening sealing, therefore be necessary to study the Updated product in this field.
Summary of the invention:
The purpose of this utility model is to solve the deficiency that above-mentioned like product exists, a kind of connecting tube external member that provide a kind of and be easy to connect, cost is low, switching performance is good.
The utility model adopts following scheme to realize: outwards swell several projectioies in the end of hollow tube, pipe cap is enclosed within protruding back, the inwall of pipe cap has the pipe cap internal thread, the front of tubing projection is a pad, what link to each other with pad is the external conical shape seal ring that is enclosed within tubing projection front end, connection pipe fitting two ends inwall has the inner conical mouth, outer wall has and the corresponding connection pipe fitting outside thread of pipe cap internal thread, the integral body that hollow tube one end and pad and external conical shape seal ring form, in the insertion connection pipe fitting, pipe cap and connection pipe fitting are by pipe cap internal thread and the stressed joint of connection pipe fitting external thread rotary.
Tubing projection one side and tight-lipped close connection of the inner conical of pad, external conical shape seal ring, connection pipe fitting.
The beneficial effect that the utility model produced: easy for installation, quick, firm and good seal performance.
Description of drawings:
Fig. 1 is the utility model connecting tube external member linkage structure sketch
Fig. 2 faces sketch for the utility model connecting tube external member China and foreign countries conical seal ring.
Fig. 3 is the utility model connecting tube external member China and foreign countries conical seal ring simplified side view.
Fig. 4 is the utility model connecting tube external member (threeway connection) linkage structure sketch.
Specific embodiment:
Below in conjunction with Brief Description Of Drawings the utility model:
As shown in the figure:
1 expression hollow tube, 2 expression tubing projectioies, 3 expression pads, 4 expression external conical shape seal rings, 5 expression connecting tube tubing, one end, 6 expression pipe caps, 7 expression pipe cap internal threads, 9 expression connection pipe fittings, 10 expression connection pipe fitting outside threads, 11 expression connection pipe fitting end inner conical mouths.
Outwards swell several projectioies (2) in the end of hollow tube (1), pipe cap is enclosed within projection (2) back, the inwall of pipe cap has pipe cap internal thread (7), the front of tubing projection (2) is pad (3), what link to each other with (3) is the external conical shape seal ring (4) that is enclosed within tubing projection (2) front end, connection pipe fitting (9) two ends inwall has inner conical mouth (11), outer wall has and the corresponding connection pipe fitting outside thread of pipe cap internal thread (10), the integral body that hollow tube one end and pad and external conical shape seal ring form, insert in the connection pipe fitting (9), pipe cap (6) screws with connection pipe fitting outside thread (10) by pipe cap internal thread (7) with connection pipe fitting (9) and is connected.
Tubing projection one side closely is connected with the inner conical mouth (11) of pad (3), external conical shape seal ring (4), connection pipe fitting (9).
Easy for installation, quick, the firm and good seal performance of the utility model.
Claims (2)
