Embodiment 1

[0034] Embodiment 1. The present invention is an automatic control fluid flow rate device, including a support frame 1. The support frame 1 provides a support foundation for the subsequent structure and plays an auxiliary support role. The right side of the support frame 1 is fixedly connected with The middle water delivery pipe 2, the front side and the upper end of the middle water delivery pipe 2 are fixedly connected with the water supply pipe 3 and the upper water delivery pipe 4 respectively, the water supply pipe 3, the middle water delivery pipe 2 and the upper water delivery pipe 4 are three The communication ensures that the sewage is transported to the upper water delivery pipe 4 through the water supply pipe 3 and the middle water supply pipe 3, and the upper water delivery pipe 4 is rotatably connected with a The propeller blade 5 on the right side of the port, the propeller blade 5 is fixedly connected to the external fixed ring, so that the fluid pushes the blade...

Embodiment 2

[0039] Embodiment 2, on the basis of Embodiment 1, due to the presence of domestic or production garbage in the sewage, a pile of pipes will be blocked, and more seriously, it will interfere with the propeller blade 5, resulting in poor rotation or stuck phenomenon, so this embodiment provides a structure for preliminary cleaning of the sundries in the sewage. Specifically, the right end of the middle water delivery pipe 2 is slidably connected with a filter screen 19, and the right end of the filter screen 19 is connected to the middle The water delivery pipe 2 fits tightly, so that the sewage can be transported upward to the water delivery pipe 4 after all the sewage is filtered through the filter screen 19. The filter screen 19 is surrounded by filter holes and the filter holes around the filter screen 19 are in line with the filter screen 19. The gap between the middle water delivery pipe 2 ensures that the sewage can pass through the filter screen 19 smoothly, reducing the...

Embodiment 3

[0040] Embodiment 3, on the basis of Embodiment 2, during the process of cleaning the filter screen 19, the sewage on the left side of the water supply pipe 3 and the middle water pipe 2 will flow to the outside with the sundries In order to reduce the leakage of sewage and avoid the long-term outflow of sewage due to the cleaning of the filter screen 19, this embodiment provides a way to place a large amount of sewage outflow. Specifically, the intermediate water delivery pipe 2 and the water supply pipe 3 are fixedly connected with Solenoid valve 22, two described solenoid valves 22 are positioned at the two ends of described filter screen 19, and two described solenoid valves 22 all are connected electrically with the control module that is fixedly connected on the described support frame 1, so The control module described above is connected to an external power supply, and a solenoid valve 22 control unit is integrated in the control module, and the two solenoid valves 22 a...

Abstract

The invention relates to an automation control device for the fluid flow speed. The problems are effectively solved that in an existing fluid flow speed control process, manual adjustment is needed, the adjustment process is inaccurate, in the flow speed control process, real-time autonomous control cannot be achieved, and a valve is blocked by impurities. According to the technical scheme, the device comprises a supporting rack, a middle water conveying pipe and an upper water conveying pipe. A propeller blade located on the right side of an upper port of the middle water conveying pipe is rotatably connected into the upper water conveying pipe, a crank driving gear is fixedly and coaxially connected to the propeller blade, a crank driven gear rotatably connected with the supporting rackis meshed with the side of the crank driving gear and coaxially and fixedly connected with a crank driving belt wheel located on the left side of the upper water conveying pipe, and the crank drivingbelt wheel is connected with the crank driven belt wheel coaxially and rotatably connected to the left end of the upper water conveying pipe. The automation control device for the fluid flow speed issimple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of pipe fittings, in particular to an automatic control fluid flow rate device. Background technique [0002] A pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with debris. Due to its unique characteristics, pipelines are widely used in many industries and fields. Pipelines are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance oil and natural gas transportation, agricultural irrigation, hydraulic engineering and various industrial installations, but in the process of pipeline transportation of fluids, large Most use control valves to control the flow rate of the fluid. [0003] In industrial production and daily life, people's activities will produce a large amount of industrial sewage or domestic wastewater. In the process of treating the above-mentioned sewage, it is inevitable to use pipelines for sewage transportation. In th...
