Abstract

The invention relates to an intelligent water pump control valve system, which comprises a vortex-free water pump control valve, monitoring terminal equipment, a water outlet pipeline, an intelligentvalve positioner, a centrifugal water pump, a first pipeline pressure sensor, a second pipeline pressure sensor, a shaft sleeve type encoder, a flow sensor and a controller. The vortex-free water pumpcontrol valve is connected with the intelligent valve positioner; the centrifugal water pump comprises a water pump body and a water pump motor; the shaft sleeve type encoder sleeves a main shaft ofthe water pump motor; the vortex-free water pump control valve is connected with the centrifugal water pump through the flow sensor and the water outlet pipeline in sequence; the first pipeline pressure sensor and the second pipeline pressure sensor are installed on the vortex-free water pump control valve; the controller comprises a PLC, a lithium battery, an electric quantity detection module, afrequency converter, a water pump starting button, a water pump stopping button and a wireless communication module, and all electronic components are connected in a matched mode. The problem that the water pump control valve is suddenly opened or closed to generate the water hammer effect is solved.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage system pipe network equipment, in particular to an intelligent water pump control valve system and a control method thereof. Background technique [0002] At present, it is one of the common ways to use centrifugal pumps for pumping in water supply and drainage systems. Combining with the working characteristics of centrifugal pumps, it is generally necessary to set a pump control valve at the outlet of centrifugal pumps to cooperate with centrifugal pumps. When the water pump control valve is suddenly opened or closed, the water hammer effect will be generated in the water pipe network. [0003] In order to prevent the water hammer effect caused by the water pipe network or prevent the reverse rotation of the centrifugal water pump. The existing water pump control valve, such as the application date of June 28, 2017, is a non-vortex type water pump control valve disclosed by th...
