Description
Technical field
The utility model relates to the direct insertion lock sealing link of agriculture slight irrigation pipeline, especially can be with microtubule and the direct-connected link of arm.
Background technique
The agricultural irrigation pipeline is mainly become by junction surfaces such as main, arm, microtubule (hollow billet) and links.Link mainly contains plug, straight-through, threeway, five-way etc.When microtubule was connected with arm, link one termination was connected with the microtubule termination is linearly, and another termination is vertical configuration with branch pipe wall and is connected, require good airproof performance, connect firm, simple and quick.Chinese patent CN2288334Y discloses a kind of " using the plastic tube jointing " more, is made up of socket joint head, socket, seal ring, and the socket joint head is made up of connecting thread, transitional surface, inverted cone surface, knurled end; The socket outer surface has afterburning post of 6-12 bar or surface knurling, and internal surface has connecting thread.Chinese patent CN2347379Y discloses a kind of " the quick link of drip irrigation pipeline ", comprises a pipeline connecting parts that is provided with three joints at least and is interconnected, and the aforementioned tube link has at least two joint peripheries to be provided with groove.Chinese patent CN2359883Y discloses a kind of " drip irrigation pipeline connecting parts ", comprises the link of the conical terrace with edge of an end band, is provided with gland nut in the inboard of the conical terrace with edge of above-mentioned band.Chinese patent CN2413495Y discloses a kind of " agricultural irrigation pipeline connecting parts ", comprises main pipe body and locking link, and main pipe body is provided with seal ring outward, and the locking link is placed in outside the seal ring and with the locking of main pipe body outer circumferential face and is connected.In above-mentioned four kinds of links, when being connected with microtubule, Chinese patent CN2288334Y discloses a kind of " using the plastic tube jointing " more, socket, seal ring will be placed in outside the microtubule earlier, they are placed on the socket joint head again, can not direct disposable connection, troublesome poeration, time-consuming, the conical surface of socket and socket joint head is a linear fit, another kind method need heat pipe, can more bother, after the temperature variation, sealing meeting variation; Chinese patent CN2347379Y discloses a kind of " the quick link of drip irrigation pipeline ", and the connection and the sealing of groove are relatively poor; Chinese patent CN2359883Y discloses a kind of " drip irrigation pipeline connecting parts ", and it is not so good that the pipe that does not wait heavy wall is connected effect; When being connected with arm, Chinese patent CN2347379Y discloses a kind of " the quick link of drip irrigation pipeline ", Chinese patent CN2359883Y discloses a end that a kind of " drip irrigation pipeline connecting parts " and Chinese patent CN2413495Y disclosed and do not have structure characteristic in a kind of " agricultural irrigation pipeline connecting parts " (it is outer and be connected with the locking of main pipe body outer circumferential face that groove, taper terrace with edge and gland nut, seal ring and locking link are placed in seal ring) and has been used for connecting branch, this known technology that is connected to, it is poor to connect sealing; Chinese patent CN2288334Y discloses a kind of " using the plastic tube jointing " more, and it does not have the technology that openly can be connected with arm.Especially present, for the ease of the multiplexing of arm and a reduction mu cost, often adopt polyethylene thin-walled plastic pipe (about thin and thick 1mm " Xiao Bai dragon ") is as the arm in the pipe network, because branch pipe wall is too thin, water shutoff is poor, the fixing of connection is poor, often because of pressure surge, expanding with heat and contract with cold causes link and arm to be thrown off, and causes the water of pipe network to leak.For avoiding the generation of above-mentioned situation, the general practice is to increase a thinner thick walled tube side by side as paying pipe when laying arm, mounting hole is beaten on pair pipe, be connected with hollow billet by the threeway of paying on the pipe, do like this and increased pair pipe and a large amount of pipe fittings undoubtedly again, fitting operation complexity not only, and increased cost.
