Abstract
The utility model discloses a water pipe switch, which comprises a switch cavity and a valve core. A water inlet pipe port and a water outlet pipe port are arranged in the switch cavity, and a water pass is arranged in the valve core. The utility model is characterized in that a cross section at a water inlet pipe opening and a water outlet pipe opening in the switch cavity is arranged into a plane, and the valve core with the water pass is arranged into a spherical body; the hole diameter of the water pass in the valve core is slightly smaller than the hole diameter of the water inlet pipe opening and the water outlet pipe opening in the switch cavity. The water pipe switch is mainly used in a water pipe network in the modern agriculture irrigating facilities; compared with the prior art, the utility model has the advantage of no leakage.
Description
Technical field
The utility model belongs to the water body switch, refers more particularly to agricultural and irrigates the conduit switch of irritating usefulness.
Background technique
Fruit tree in the modern agriculture, vegetables, melon and fruit, gardening, agricultural greenhouses etc. adopt drip irrigation, sprinkling irrigation, mist is irritated all will catch to establish and is irrigate the filling facility, generally form and irrigate the water pipe networking of irritating in the facility by water main and distributed water pipe, joint at water main and distributed water pipe is provided with switch, its switch comprises the switch cavity, spool, intake pipe opening and outlet pipe opening are arranged in the switch cavity, the cross section of their opening is arc surface, the cylndrical surface of sky in the inwall of this arc surface and switch cavity forms, and its spool is a cylindrical body, one water port is arranged in the cylindrical body, because the cylndrical surface of cylindrical body spool and switch cavity inner wall relatively rotates, switch cavity inner wall and spool are worn and torn easily and the generation slit, thereby seepage often appears, waste the liquid manure resource.
Summary of the invention
The technical problem that the utility model solved is: the conduit switch that a kind of ne-leakage is provided.
For solving the problems of the technologies described above, the technological scheme that is adopted: a kind of conduit switch, comprise switch cavity, spool, intake pipe opening and outlet pipe opening are arranged in the switch cavity, be provided with the water port in the spool, be characterized in that the intake pipe opening in the switch cavity and the cross section of outlet pipe opening be arranged to the plane, the spool that is equipped with the water port is arranged to spherical surface body.
The aperture of the water port in the spool is slightly less than the interior intake pipe opening of switch cavity and the aperture of outlet pipe opening.
Compared with prior art, the utility model has the advantages that because the plane is arranged in the cross section of intake pipe opening in the switch cavity and outlet pipe opening, the spool that is equipped with the water port is arranged to spherical surface body, and the aperture of the water port in the spool is slightly less than the interior intake pipe opening of switch cavity and the aperture of outlet pipe opening simultaneously.When the need switch is in closed condition, rotational valve core, make that the part sphere of sphere core is protruding to be advanced and tightly be attached on water inlet openings and the water outlet opening inwall, water can not ooze out from water intake, when the need switch is in opening state, rotational valve core, the water port that makes sphere core communicates with intake pipe opening and outlet pipe opening in the switch cavity, because the aperture of the water port in the spool is slightly less than the interior intake pipe opening of switch cavity and the aperture of outlet pipe opening, the sphere of the part that the water port is other also is protrudingly to advance and tightly be attached on water inlet openings and the water outlet opening inwall, and water can not ooze out from water intake or water outlet; Thereby reached the purpose of the utility model ne-leakage.
