Problems solved by technology

Irrigation valves play the role of reversing and blocking water flow in the irrigation pipe network, and are closely related to water flow during operation. Therefore, the driving force of irrigation valves implements the principle of proximity, that is, hydraulic power is selected as the main driving force, and electricity or gas is the main driving force. The power is coordinated to provide the driving power for the valve drive; however, the existing valve drive devices for irrigation have the problems of low controllability and high energy consumption

Abstract

The invention discloses a valve driving device for irrigation. The device comprises a membrane top cover, a membrane, a connection plate, a first connecting piece, a second connecting piece and a water sealing cover. The membrane top cover is arranged above the membrane, the first connecting piece is arranged below the membrane and used for connecting the membrane top cover with the membrane through a thread, the second connecting piece is arranged above the water sealing cover, the connection plate is connected with the first connecting piece and the second connecting piece through a plug pin, and the membrane and a valve body component form a hollow cavity. The purpose of controlling a valve to be opened is achieved by controlling the value of water pressure in the cavity.

Description

technical field [0001] The invention relates to the field of irrigation valves, in particular to an irrigation valve driving device. Background technique [0002] The driving device of the valve is the field device that controls the opening, closing and automatic adjustment of the valve in the system. Its function is to convert the signal into corresponding mechanical displacement and change the medium flow, so as to achieve the purpose of controlling parameters. The safety, reliability and controllability of the valve driving device have a great influence on the operation of the system, and excellent controllability can greatly improve the energy saving effect. [0003] According to different driving forces, the valve driving device can be divided into electric, pneumatic, hydraulic or any combination of the three. Irrigation valves play the role of reversing and blocking water flow in the irrigation pipe network, and are closely related to water flow during operation. Th...
