Abstract
The utility model relates to a bend for a gas pipe body, which comprises a bend body which is composed of two straight-pipe sections and a bent-pipe section, wherein, inner screw threads are respectively arranged on the inner walls of the two straight-pipe sections, outer screw threads are evenly arranged on the outer walls of the outer ends of the two straight-pipe sections, the outer ports of which are provided with grooves of which the inner walls are outwards inclined, and each groove is embedded with a sealing ring; the screw thread points of the outer ends of the two straight-pipe sections are respectively connected with a sealing nut by screw threads, and a sealing ring is arranged in the sealing nut. The utility model has the advantages of simple structure, safety and good sealing effect.
Description
(1) technical field
The utility model relates to a kind of elbow, particularly relates to a kind of gaspipe line elbow that designs according to gaspipe line engineering new process.
(2) technical background
Coal gas is a kind of clear energy sources, and easy to use, and the vast cities and towns of China have been extensive use of piped gas, do civilian and industrial fuel.The common elbow that gaspipe line installing engineering is at present used is to adopt the single-stage seal arrangement, and sealing effect is bad, and leakage gas causes potential safety hazard easily, can not guarantee the quality of coal gas installing engineering.In addition, the area of contact on existing gaspipe line elbow and ground is little, will move by occurrence positions when certain external pressure, makes elbow easily produce distortion and gas leakage.
(3) summary of the invention
The utility model provides a kind of and has double sealing structure and be difficult for producing the gaspipe line elbow that move the position for solving the problem that above-mentioned prior art exists.
The technological scheme that adopts is:
The gaspipe line elbow comprises curved head body.Curved head body is made of the bend loss between two straight lengths and two straight lengths, be respectively equipped with internal thread on the inwall of two straight lengths, be equipped with outside thread on the outer wall of two straight length outer ends, the screw thread place of two straight length outer ends is respectively with the sealing nut that is threaded.Be equipped with seal ring in the sealing nut.
The external port of above-mentioned two straight lengths has the outward-dipping groove of inwall, and the groove place of two straight length outer ends all embeds the seal ring of a tapered sleeve shape.
Solid welding has one to lift on the outer wall of the bend loss of above-mentioned curved head body.
During installation, with the outer wall mantle fiber of gas pipe termination, insert in the curved head body then, and be tightened on the internal thread of curved head body straight length earlier.Embed a tapered sleeve rubber seal ring at the groove place of straight length outer end then, be tightened on the outside thread of curved head body straight length outer end with the sealing nut that tapered sleeve sealed nylon ring is housed again, to reach the twin-stage sealing of whole gaspipe line.
The utility model is owing to the bend loss solid welding at elbow has one to lift.Thereby when gaspipe line was installed, lifting on the gaspipe line elbow can be placed on the prefabricated cemented platform, guaranteed that the gaspipe line elbow is difficult for producing the position and moves, thereby can avoid the gaspipe line elbow to produce distortion because of being subjected to external pressure, even leak.The main advantage of the utility model is to be provided with internal thread on the inwall of elbow straight length, gas pipe is tightened in earlier on the interior internal thread of elbow straight length, simultaneously be equiped with the tapered sleeve rubber seal at the groove place of elbow straight length outer end again, this tapered sleeve rubber seal is fixed by sealing nut, thereby reach the twin-stage sealing of gaspipe line elbow, avoid the easily phenomenon of gas leakage of gaspipe line joint effectively, guaranteed the quality of gaspipe line installing engineering.
(4) description of drawings
Fig. 1 is an a kind of embodiment's of the present utility model structural representation.
(5) embodiment
The gaspipe line elbow, comprise curved head body 1, curved head body 1 is made of two straight lengths 2,3 and the bend loss 4 between two straight lengths 2 and 3, wherein be respectively equipped with the internal thread 5 that coal supply tracheae 12 is threaded on the inwall in the straight length 2,3, the inwall of two straight lengths 2 and 3 outer ends is outward-dipping formation one groove 6 respectively, be respectively equipped with the outside thread 8 that is tightened for sealing nut 7 on the outer wall of two straight lengths 2 and 3 outer ends, be equipped with seal ring 9 in two sealing nuts 7, seal ring 9 is a tapered sleeve shape sealed nylon circle.It is tapered sleeve shape rubber seal that the groove place embedding of two straight length 2 outer ends has seal ring 10, seal ring 10.Sealing circle 10 with the gap sealing between two gas pipe 12 and two straight lengths 2 and external port of inserting in the curved head bodies 1 firmly.After two sealing nuts 7 were tightened on the outer end of two straight lengths 2 and 3, seal ring 9 was tightly replaced on seal ring 10, combines closely.For curved head body 1 can be crouched on prefabricated cement platform by seat, solid welding has one to lift 11 on the outer wall of straight length 3.
Claims (3)
1, gaspipe line elbow, comprise curved head body (1), curved head body (1) is made up of two straight lengths (2) and (3) and a bend loss (4), be equipped with the outside thread (8) that is tightened for sealing nut (7) on the outer wall of two true pipeline sections (2) and (3) outer end, be set with seal ring (9) in the sealing nut (7), it is characterized in that being respectively equipped with the internal thread (5) that coal supply tracheae (12) front end screws togather on the inwall of two straight lengths (2) and (3).
2, gaspipe line elbow according to claim 1 is characterized in that the external port of two straight lengths (2) has the outward-dipping groove of inwall (6), and groove (6) is located to embed seal ring (10).
3, gaspipe line elbow according to claim 1 and 2 is characterized in that solid welding has one to lift (11) on the outer wall of the bend loss (4) of curved head body (1).
