Abstract
The utility model discloses a pipe connector in an agricultural micro-irrigation system, which comprises a pipe body and a lock nut, wherein the pipe body is provided with at least one tubular billet connecting end; a conical frustum of a pyramid is arranged at the tubular billet connecting end; the end surface of the conical frustum of a pyramid is axially vertical to the pipe connector; a thread matched with the lock nut is arranged on the inner side of the conical frustum of a pyramid; an annular groove is arranged between the segment with the thread and the conical frustum of a pyramid; the outer end of the lock nut is a conical surface; a flat straight segment is arranged behind the conical surface; the inside diameter of the flat straight segment is smaller than the largest diameter of the conical frustum of a pyramid; and the lock nut is screwed through the conical frustum of a pyramid through outer threads of the pipe connector. Therefore, the pipe connector has the advantages of firm connection, good sealability, no leakage, simple structure and convenience for operation.
Description
Technical field
The utility model relates to the pipeline connecting parts in the agriculture irrigation system, especially connects the link of hollow billet.
Background technique
The agricultural irrigation system is made up of main, arm, hollow billet.Need pipeline connecting parts to be connected between hollow billet and the arm, Chinese patent ZL99203491.4 discloses a kind of pipeline connecting parts, it comprises the link with conical terrace with edge, and the inboard of terrace with edge is provided with gland nut, during use, earlier pipe is placed on the conical terrace with edge of link, gland nut is screwed out until with the hollow billet jam-packed, owing to be side seam formula drip irrigation zone, the latasuture place is a labyrinth flow-path in use again, uneven thickness when gland nut is pressed the drip irrigation zone leaks easily in labyrinth flow-path one side.Chinese patent specification CN2413495Y discloses a kind of farmland drip irrigation pipeline connecting parts, and it 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.But the drip irrigation zone will be passed the locking link earlier during use, is inserted in the main pipe body outer circumferential face again, because main pipe body is provided with seal ring outward, the drip irrigation zone belongs to thin walled hose, easily bends when seal ring is passed in the drip irrigation zone, is difficult for being inserted in main pipe body, inconvenient operation.
Summary of the invention
The purpose of this utility model is to provide a kind of can directly be connected and connect firm, good airproof performance, simple and quick slight irrigation pipeline connecting parts with hollow billet.
To achieve these goals, the technological scheme that the utility model is taked is: it comprises main pipe body and the locking nut that is provided with at least one hollow billet connecting end, be provided with the taper terrace with edge at the hollow billet connecting end, the end face of taper terrace with edge is for axially being provided with one section screw thread that matches with locking nut in inboard vertical, the taper terrace with edge with pipe connector, between screw thread place section and the taper terrace with edge annular groove is arranged, the outer end of locking nut is the conical surface, one section flat segments is arranged after the conical surface, the internal diameter of flat segments is littler than the maximum diameter of taper terrace with edge, and locking nut is crossed the taper terrace with edge by the pipe connector external thread rotary.During use, earlier locking nut is crossed the taper terrace with edge by the pipe connector external thread rotary, hollow billet overlapped pipe connector taper terrace with edge, was inserted in the locking nut, locking nut was screwed out until locking nut the hollow billet jam-packed again, and hollow billet just can not leak and slippage like this.
The maximum diameter of the taper terrace with edge of above-mentioned slight irrigation pipeline connecting parts is than the big 0.2mm～0.5mm of hollow billet internal diameter.
Be provided with seal groove in the annular groove behind the above-mentioned slight irrigation pipeline connecting parts taper terrace with edge, seal ring is located in the seal groove, and the external diameter of seal ring is no more than the maximum diameter of taper terrace with edge.
The beneficial effects of the utility model are: because the end face of taper terrace with edge is axially vertical with pipe connector in the slight irrigation pipeline connecting parts, therefore make that hollow billet and slight irrigation pipeline connecting parts are that line contacts, be connected firmly, good airproof performance and ne-leakage, simple in structure, easy to operate.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
