Throttling device

The invention discloses a throttling device, which comprises a water pipe main body, a flow limiting block, a connecting rod, a flow limiting surface, a spring and an adjusting bolt. The two ends of the water pipe main body are respectively provided with an inlet connection end and an outlet connection end. The water pipe The outlet connection end of the main body is integrally formed with a flow-limiting surface, and a flow-limiting cavity is formed inside the flow-limiting surface. The cross-sectional area of ​​the flow-limiting cavity decreases linearly from the inlet connection end to the outlet connection end. The upper and lower ends are symmetrically provided with mounting holes, one end of the connecting rod is placed in the mounting hole, the other end of the connecting rod is fixedly installed on the current limiting block, the spring is placed in the mounting hole, and the adjusting bolt passes through the The threaded structure is installed on the outer end of the mounting hole, one end of the spring is fixedly connected with the connecting rod, and the other end of the spring is against the adjusting bolt. This equipment can be adjusted according to the water pressure of the flow, so that the water flow in the pipeline is always at a stable value, and the purpose of saving water is achieved.
