Abstract
The utility model relates to a special coal gas service bend pipe for a coal gas conveying pipeline. The utility model is characterized in that both ends or one end of the bend pipe is provided with a sealing rubber ring and a faucet of a tight pressing member; the sealing rubber ring is provided with a support ring and is connected with a pipe fitting; the curved angle of the bend pipe is from 88 DGE to 89 DGE; the inside diameter of the bend pipe is changed from one end to the other end.
Description
The utility model relates to a kind of coal gas special use that is used for gas conveying tube road curved tube of registering one's residence.
Being used to connect the register one's residence curved tube of pipe of coal gas at present all is 90 ° of habitual elbows of tradition, and 95% leakage point occurs in elbow or connected loose joint place, and therefore catches fire and explosive accident.Therefore the reason of its gas leakage is that elbow is rigid the connection with the gas conveying tube road, in construction or installation process and elbow is cracked cause gas leakage.And necessary adapted loose joint with the elbow connecting pipeline time, it has not only increased engineering cost, and easily produces gas leakage.Bent angle owing to elbow is 90 ° in addition, and its caliber is identical with the caliber of connecting tube, therefore easily produces the water blocking phenomenon.
The purpose of this utility model is, in order to overcome the deficiency of above-mentioned elbow, provide a kind of reasonable in design, safe and reliable, usability is good, the life-span is long, be difficult for producing water blocking, curved tube is registered one's residence in the coal gas special use of being convenient to construct, save operating expenses.
Technical solution of the present utility model is for the ease of constructing and preventing gas leakage, the curved tube (elbow) of connecting pipeline to be made the bellmouth of two ends for supplying to adorn support ring, the O-ring seal that is connected with pipe fitting and pressing part.Also curved tube can be made the bellmouth of an end for supplying to adorn support ring, the O-ring seal that is connected with pipe fitting and pressing part in order further to reduce cost, the other end is screwed interface.It presses part can be by flange or screw threads for fastening in the bellmouth of curved tube.In order to make curved tube not have adverse slope, promptly prevent to produce the water blocking phenomenon, it is 80 °-89 ° that curved tube is made bent angle, internal diameter passes through and is the curved tube of reducing.In order to prevent in construction, to cause curved tube to break, increased the thickness of curved tube wall.
The utility model and background technique are relatively, one, because curved tube has been made the bellmouth that both ends or one end supply to adorn support ring, the O-ring seal that is connected with pipe fitting and press part, therefore make curved tube and gas conveying tube road rigid be connected to become flexibly connect, it has not only prevented breaking of curved tube and has leaked, and make connecting tube that degrees of freedom arranged, and cancelled slip-knot, and brought convenience to construction, reduced operating expenses.Two, be 88 °-89 ° owing to curved tube has been made bent angle, internal diameter is the curved tube of reducing, therefore, has effectively eliminated and has carried the phenomenon that produces water blocking in the course of gas.Three, because this curved tube is the grafting form in pipeline,, therefore not only can improves efficiency of construction, and improve the working life of pipeline so do not destroy the anticorrosive coat of galvanized pipe.
Describe two specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment 1 a structural representation.
Fig. 2 is the utility model embodiment 2 a structural representation.
Embodiment 1
Referring to Fig. 1, this routine coal gas special use register one's residence curved tube 1 be two ends be have flange for dress support ring, the O-ring seal that is connected with pipe fitting and press the bellmouth 2 of part.Its bent angle is 89 °, and its internal diameter passes through and is reducing.
During construction, ring high density polyethylene (HDPE) support ring is put into the bellmouth of curved tube, with pipe fitting that curved tube is connected on be with the part that presses that O-ring seal and an end have flange, and will be enclosed within the O-ring seal on the pipe fitting and press the bellmouth that part is put into curved tube, to press part by bolt then and be fastened in the bellmouth of curved tube, O-ring seal is pressed solidly in the bellmouth of curved tube by pressing part.
Referring to Fig. 2, this routine coal gas special use register one's residence curved tube 1 be one one end be have flange for dress support ring, the O-ring seal that is connected with pipe fitting and press the bellmouth 2 of part, the other end is the interface 3 that has internal thread.Its bent angle is 88 °, and its internal diameter is the reducing that enlarges gradually from the threaded end to the female end.
During construction, the form of construction work of its curved tube female end is identical with embodiment 1.Its threaded end directly is connected with pipe fitting by screw thread.
