Description

Pipeline valve structure for irrigation Technical Field The utility model relates to the technical field of pipeline valves for agricultural irrigation, in particular to a pipeline valve structure for irrigation. Background This company has applied for irrigation pipeline valve in 2025 12 month 02 day, this pipeline valve drives driving gear mainly through driving motor, and then through driving gear drive ring gear, the rethread is transmitted the screw thread fit mode between ring gear and the case, realize driving the case translation through the rotation of ring gear, and the friction contact surface is more between the outer wall of above-mentioned mode transmission ring gear and case, transmission efficiency is low, at the in-process of operation, the required power of ring gear is great, consequently, the structural strength to ring gear and driving motor power requirement are higher, so increased the use cost of pipeline valve. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide the pipeline valve structure for irrigation, which adopts a transmission mode of meshing a rack and a driving gear to replace the traditional threaded fit, reduces the contact area of transmission parts, reduces the driving force requirement and the structural strength requirement, and solves the problem of high use cost. The technical scheme is that the pipeline valve structure for irrigation comprises a valve body, a valve seat and a valve core, wherein the valve seat and the valve core are arranged in the valve body, the valve core slides back and forth in the valve body, one end of the valve seat, which faces the valve core, is provided with a sealing surface, the sealing surface is abutted against the end part of the valve core, the side wall of the valve core is provided with a rack extending along the axial direction of the valve core, the position, close to the rack, of the outer side wall of the valve body is provided with a driving motor, a rotating shaft of the driving motor is connected with a driving gear in a linkage mode, and the driving gear is meshed with the rack. As a further improvement of the utility model, the valve body is provided with a water inlet and a water outlet, one end of the valve core facing the water inlet is a pressed end surface, and a gap is reserved between the driving gear and the rack so as to enable the pressed end surface to be pressed towards the sealing surface of the valve seat after bearing the pressure of a medium. As a further improvement of the utility model, the side wall of the valve core is provided with a limiting plate extending along the axial direction of the valve core, the valve body is internally provided with a limiting hole extending along the axial direction of the valve core, and the limiting plate can be slidably arranged in the limiting hole so as to limit the valve core to move only axially in the valve body. As a further improvement of the utility model, the rack is arranged on the side wall of the limiting plate, the driving gear is coaxially fixed with a rotating shaft, one end of the rotating shaft, which is opposite to the driving gear, penetrates out of the valve body, and is coaxially sleeved with the driven gear, and the driven gear is linked with the rotating shaft of the driving motor through the gear set. As a further improvement of the utility model, two limiting plates are arranged side by side, a space is reserved between the two limiting plates, the driving gear is positioned in the space, and the rack is arranged on one surface of one limiting plate facing the driving gear.
