Description

A three-way valve for agricultural water-saving irrigation

Technical Field

The utility model relates to a three-way valve for agricultural water-saving irrigation, and particularly relates to the field of valves.

Background Art

A valve is a device commonly used in pipelines to control the flow of liquid in the pipeline, thereby controlling and blocking the flow of the liquid. Valves used in agricultural water-saving irrigation generally use one-way valves. Valves are generally composed of a valve body, a baffle, a rotating shaft and a screw plate. When in use, the openings on both sides of the valve body are connected to the water inlet pipe and the outlet pipe respectively, and then the rotating shaft is driven to rotate by turning the screw plate. After the rotating shaft rotates, it drives the baffle to rotate, thereby opening it to allow water to pass through. Otherwise, the baffle is closed to intercept the water flow.

The specification of Chinese patent CN201821735660.4 discloses a three-way valve for agricultural water-saving irrigation equipment with a quick-connect hard pipe. The three-way valve for agricultural water-saving irrigation equipment with a quick-connect hard pipe comprises a three-way valve assembly, a double-connected plastic body respectively assembled on the left and right sides of the three-way valve assembly, and a hard pipe assembly part assembled on the third side of the three-way valve assembly; the three-way valve assembly comprises an injection-molded main body, and the injection-molded main body comprises a transverse injection-molded main body and a vertical injection-molded main body integrally connected in a T shape; connecting pipes are integrally connected to the left and right sides of the transverse injection-molded main body, and the connecting pipes are integrally connected to a threaded pipe, and the threaded pipes on both sides are respectively threadedly assembled with the plug-in end with an internal thread on one side of the double-connected plastic body, and a sealing part is assembled in the plug-in end on the other side of the double-connected plastic body; a valve body with a valve switch is connected to the middle part of the vertical injection-molded main body; a single-connected plastic body is integrally connected to the end of the vertical injection-molded main body, and a hard pipe assembly part is assembled with the internal thread of the plug-in end of the single-connected plastic body. The new quick-connect hard pipe bypass three-way valve can be quickly connected to the capillary pipe after connecting to the main pipe. It is easy to install and disassemble and convenient for construction.

In the above patent, a double-connected plastic body is connected to an external pipe through a threaded pipe, thereby realizing quick connection of a capillary pipe, which is easy to install and dismantle for convenient construction. However, compared with traditional valves, when in use, the torque of the rotating shaft is relatively large, and the sealing effect of the sealing gaskets at both ends of the baffle is relatively poor, allowing water to seep out easily, thereby causing waste of water resources. At the same time, the water flow cannot be accurately controlled, further leading to loss of water resources. Traditional valves are large in size and have a relatively complicated internal structure, which makes the production process difficult, resulting in high production and assembly costs.

In summary, the valve body is connected to the second connecting pipe by using the first connecting pipe. After the second connecting pipe is connected to the water inlet pipe by using a thread, the operation of the rotating shaft and the transmission shaft can be controlled through the manual switch hole. The operation of the transmission shaft can drive the operation of the baffle, etc., thereby achieving precise control of the water flow.
