Abstract
The utility model discloses a connection pipe fitting of a water-meter pipe, which comprises a water meter, a connection pipe, a connection nut and the structure of connection joints of a pipeline, wherein inner screws of the connection nut is screwed in outer screws of the connection joints of the pipeline of the water meter. The curved surface of the connection nut is abutted on one side of the cambered surface of the connection pipe; the other side of the cambered surface of the connection pipe, which is abutted on the inner cambered surface of the connection joints of the pipeline of the water meter, is sealed. The utility model has the advantages of convenient connection, firm seal and convenient operation; the work efficiency can be enhanced, the utility model can reach the match of the connection of the pipeline; the utility model puts an end to the defects that adhesive joints are infirm, and the inner diameter is reduced when the utility model is inwards concave; the utility model overcomes the defects that the utility model is difficult to keep sealing elements be free from aging, so the phenomenon of leaking can happen after a certain time, and the accidental loss can be caused; the utility model has the obvious characteristic that the utility model is free from the influence of overheating; the application range is enlarged.
Description
One, technical field:
A kind of pipe fitting for connecting water meter pipeline of the utility model, what relate to is pipeline and pipeline connecting pipe fitting technical field, particularly plumbing pipe and pipeline connecting pipe fitting technical field thereof are applied to copper pipe, thin-wall stainless steel, stainless steel-plastic composite pipe.
Two, background technique:
At present, the hot-water heating pipe of being supplied on the market adopts traditional galvanized pipe substantially, the pipeline of copper tube, its Placement is continued to use the outer silk of pipeline processing, no matter straight joint, elbow, pipe joints such as threeway, all should connect with pipe joint with internal thread, very easy oxide etch has influenced actual working life, polluted water, aluminium-plastic composite pipe can overcome and reduce water pollution, connect though use bayonet connection can carry out pipeline, intensity is lost in the aluminium skin corrosion of centre, cause plastic-aluminum combined tracheal rupture owing to reaching in water oxygenization easily, leak, because aluminium-plastic composite pipe is caught a cold by heat expansion to contract easily, the time one is of a specified duration, has influenced the sealing of bayonet connection again, the water leakage phenomenon that is caused happens occasionally, connect the defective that does not match owing to exist water meter simultaneously, influenced applying of aluminium-plastic composite pipe
Three, summary of the invention:
The purpose of a kind of pipe fitting for connecting water meter pipeline of the utility model is the structure of conversion water meter link, and it is firm to make water meter reach long-time connection.Its technology is achieved in that the structure that comprises water meter, connecting tube, attaching nut, pipe connector lug, it is characterized in that: attaching nut's internal thread screws in the water meter pipe connector lug outside thread, connecting tube cambered surface one side of attaching nut's curved surface conflict stainless steel-plastic composite pipe, connecting tube cambered surface opposite side and water meter pipe connector lug intrados are conflicted and are sealed, and described intrados can be cambered surface or inclined-plane.Its tangible advantage is that easy to connect, it is firm to seal, operation is convenient, improve work efficiency, reached supporting that pipeline connects, stopped the defective that bonding not firm and indent reduces internal diameter, overcome the employing Sealing, be difficult to guarantee that Sealing is not aging, may take place later to give birth to water leakage phenomenon in a period of time thus, can cause the defective of unexpected loss equally, have the evident characteristic that is not subjected to overheated influence again, enlarged application area.
Four, description of drawings:
Fig. 1 is the structural representation that a kind of water meter connects embodiment;
Wherein, 1-stainless steel-plastic composite pipe, 2-attaching nut, the outer convex globoidal of 3-, 4-water meter, 4-1-intrados, 5-attaching nut, 6-stainless steel-plastic composite pipe, the outer convex globoidal of 7-;
Five, embodiment:
Below in conjunction with the pipeline connection of accompanying drawing the utility model is further described water meter:
See accompanying drawing 1, be inserted in the attaching nut (2,5) of the stainless steel-plastic composite pipe (1,6) that is processed into outer convex globoidal (3,7), attaching nut (2,5) internal thread screws in the pipe connector lug outside thread at water meter (4) two, outer convex globoidal (4, a 7) side of attaching nut (2,5) curved surface conflict stainless steel-plastic composite pipe (1,6), the pipe connector lug intrados (4-1) of stainless steel-plastic composite pipe (1,6) outer convex globoidal (4) opposite side and water meter (4) is conflicted and is sealed.
See accompanying drawing 1, intercepting stainless steel-plastic composite pipe (1,6) length, be inserted in attaching nut (2,5), expand the outer convex globoidal (4 of the connecting tube that two end evaginations with the expanding device, 7), make every stainless steel-plastic composite pipe (1,6) the outer convex globoidal (4 of the connecting tube of two end evaginations, 7) two attaching nuts (2 between, 5) can't deviate from, the attaching nut (2,5) internal thread screws in water meter (4) pipe connector lug outside thread, the attaching nut (2,5) curved surface conflict stainless steel-plastic composite pipe (1,6) the outer convex globoidal (4 of connecting tube, 7) side, the outer convex globoidal (4 of connecting tube, 7) opposite side and pipe connector lug intrados (4-1) are conflicted and are sealed.
Claims (2)
