Description

Technical Field

[0001] The utility model relates to the technical field of farmland irrigation, and particularly relates to a protection device for a water supply valve for farmland irrigation. Background Technique

[0002] As a water supply device, a water hydrant provides water source to the ground pipeline under the action of pressure. Water hydrants are widely used in agricultural and forestry irrigation, which facilitates people's lives. However, during daily use, water hydrants are very likely to be impacted by external objects, and being exposed outside for a long time is likely to cause rust and aging, resulting in damage to the water hydrant, making the water hydrant unable to be used normally, and affecting the irrigation efficiency in the field of agricultural and forestry irrigation. Therefore, people will set protective measures for the water hydrant to prevent it from being unable to be used normally.

[0003] Existing water hydrants generally consist of structures such as a valve housing, a valve cover, a rotating lead screw, a lead screw nut matching with the rotating lead screw, and a hanging ring. The water hydrant with this structure has poor sealing performance, and there is often water leakage between the valve housing and the valve cover; the valve housing and the hanging ring are generally integrally cast, and the process is relatively complex.

[0004] In the patent document with the publication number: CN202769000U, a water hydrant for farmland irrigation is proposed. The device includes a valve housing, a valve cover, a rotating lead screw, a hanging ring, and a lead screw nut fixed inside the valve housing and matching with the rotating lead screw. The key technology lies in: the valve housing is a valve housing formed by rolling and welding steel plates. At the upper opening of the valve housing, there is a bent annular platform for sealing, and the annular platform and the valve housing are of an integral structure. A sealing gasket is fixed under the valve cover. The advantages of the utility model are: an annular platform is provided, which cooperates with the sealing gasket to well prevent water leakage; the valve housing is formed by rolling steel plates, and the hanging ring is spot-welded to the valve housing. The water hydrant with this structure is convenient to manufacture and can reduce production costs; an annular groove is provided at the lower part of the valve housing, which can better seal and connect with the main pipeline tee.

[0005] However, this device lacks a protection structure for the water supply valve, so it is easy for the water hydrant to be damaged by external impacts.

[0006] Therefore, we urgently need to provide a protection device for a water supply valve for farmland irrigation. Content of the Utility Model

[0007] The purpose of the utility model is to provide a protection device for a water supply valve for farmland irrigation to solve the problem that the device lacks a protection structure for the water supply valve in the above-mentioned background technique, so that the water hydrant is easily damaged by external impacts.

[0012] Preferably, the material of the protection cylinder is pcabs alloy material, which is more environmentally friendly, can be degraded, and can also be recycled. The protection plates are symmetrically distributed in pairs inside the protection cylinder, thereby improving the protection performance of the device for the water supply valve.

[0013] Preferably, the connection end of the adjustment disc is in threaded connection with the inside of the top end of the mounting disc, which is convenient for installing the adjustment disc and also for replacing other adjustment discs.
