Control valve for controlling water flow through relay

Abstract

The invention discloses a control valve for controlling water flow through a relay. The control valve comprises a valve body. A water cavity is arranged in the lower half portion of the interior of the valve body in a left-right penetration mode. The upper side of the water cavity is provided with a lifting cavity. A lifting plate capable of sliding up and down is arranged in the lifting cavity. The lower end of the lifting plate is fixedly provided with a valve control plate extending into the water cavity. A water energy device is arranged at the center of the interior of the valve control plate. The water energy device is internally provided with a water wheel cavity located at the center of the interior of the lower end face of the valve control plate, and an opening of the water wheelcavity faces downwards. A water wheel shaft is rotatably arranged between the front and rear walls of the water wheel cavity. The control valve controls opening and closing of the water inlet end andthe water outlet end through the relay by detecting the pressure of input water and the pressure of output water, adjusts the water flow according to the flow velocity of water, then adjusts the flowcapacity of the water flow, automatically adjusts input water and output water according to the flow rate of the water inlet end and the flow rate of the water outlet end to ensure balance of the water inlet end and the water outlet end, realizes automatic water control without manual adjustment and is quite convenient to use.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to a control valve using a relay to control water flow. Background technique [0002] In some water conservancy projects or where water is needed, when water is diverted and transported, the water flow needs to be controlled according to the actual water intake and flow rate. Ordinary control valves need to manually control the actual water flow and flow rate. Real-time adjustment is troublesome. Some existing intelligent control valves can realize real-time monitoring and adjustment of water flow, but they are large in size and inconvenient to use. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical problem: [0004] Some of the existing control valves need to be adjusted manually in real time, and some of them are relatively large in size and inconvenient to use. [0005] In order to s...

[0002] In some water conservancy projects or where water is needed, when water is diverted and transported, the water flow needs to be controlled according to the actual water intake and flow rate. Ordinary control valves need to manually control the actual water flow and flow rate. Real-time adjustment is more troublesome. Some existing intelligent control valves can realize real-time monitoring and adjustment of water flow, but they are large in size and inconvenient to use.
