3results about How to "Flow adjustment" patented technology

This application provides a water treatment filtration device, belonging to the field of filtration devices, to solve the problem of inconvenient adjustment of water flow rate. It includes a treatment tank, a square tube fixedly connected to the tank, a connecting shaft connected to the square tube via a sealed bearing, a bracket fixedly connected to the tank body, and a second spring fixedly connected inside the tank body. This application includes a baffle; when the square tube is conveying water and the flow rate needs to be adjusted, the connecting bracket can be pulled to move a limiting plate. The limiting plate can compress the first spring inside the rotating housing, and simultaneously, the locking block on the limiting plate can disengage from the slot in the square tube. The rotating housing can be rotated, driving the baffle to rotate via the connecting shaft, adjusting the baffle's tilt angle, and controlling the flow space in the square tube. Releasing the connecting bracket, under the push of the first spring, causes the limiting plate and locking block to reset, and the locking block can engage with the square tube, fixing and limiting the adjusted baffle to allow for flow rate adjustment as needed.

The application belongs to the technical field of building construction, and discloses a concrete vertical conveying device and a concrete vertical conveying speed adjusting method. The concrete vertical conveying device comprises a flow guide cylinder, a speed reduction assembly, a flow speed monitoring member and a control unit. The speed reduction assembly is installed in the flow guide cylinder and comprises a support member and a speed reduction member. The support member is detachably connected to the flow guide cylinder. The speed reduction member comprises a plurality of speed reduction blades which are arranged in a circumferential direction of the support member at intervals. The speed reduction blades are rotatably arranged on the support member along the extension direction of the speed reduction blades. A plurality of spiral channels are formed on the surfaces of the speed reduction blades, and the concrete flows along the spiral channels. The flow speed monitoring member is configured to monitor the flow speed of the concrete. The control unit is configured to adjust the rotation angle of the speed reduction blades according to the flow speed monitored by the flow speed monitoring member. The concrete vertical conveying device can flexibly adjust the conveying speed of the concrete in a self-adaptive manner, reduces the risk of concrete segregation, ensures the concrete pouring quality, and improves the convenience of maintenance and repair.

The utility model discloses a greening maintenance irrigation device which comprises a water supply pipe, the top of the water supply pipe is connected with a driving box, the driving box is provided with a driving device, the driving box is rotationally provided with a rotating pipe installation pipe, the installation pipe is provided with a plurality of adjusting pipes, a flow speed adjusting device and a spray head in an array mode, and the flow speed adjusting device comprises a fixed plate and a movable plate. Adjusting elastic pieces are arranged between the fixed plate and the movable plate, adjusting blocks are arranged on one sides of the adjusting elastic pieces, adjusting rods and adjusting plates are rotationally arranged in the adjusting pipes, and fixing blocks are arranged between the adjusting elastic pieces in the adjusting pipes. By arranging the flow speed adjusting device, the water flow speed on the adjusting pipe and the spray heads can be conveniently adjusted, water with different flow speeds can be sprayed through the spray heads with different heights, the coverage area of the water flow can be adjusted, and then the irrigation area of the water flow can be conveniently adjusted according to needs.
