A self-regulating flow speed reducer

Abstract

The invention relates to a self-regulation flow speed slowing device. The flow speed slowing device comprises a slowing mechanism as well as a shell and an end cover which are matched with the slowing mechanism for use; the slowing mechanism is formed by a sector connection frame and stop blocks; included angles of 120 degrees are formed among three blades of the sector connection frame; the center of the connection frame is connected into the shell by a rolling bearing and can freely rotate in the shell; the stop blocks are arc, are connected to the tail ends of the sector connection frame and are matched with the inside of the shell in shape. Compared with the prior art, the stop blocks are rotated under the action of a water flow, and an inlet is blocked once when each stop block is rotated by 120 degrees, when the flow speed is increased, the corresponding rotary angular speed of the stop blocks 4 is accordingly increased, the frequency of blocking the inlet by the stop blocks is accordingly increased, and finally the flow speed and the angular speed achieve a balance.

Description

technical field [0001] The invention relates to a flow velocity regulating device, in particular to a self-regulating flow velocity retarder for reducing and stabilizing the flow velocity of liquid. Background technique [0002] Nowadays, in many places, especially big cities, in order to supply water to high floors, high water pressure is often added, but for users of low floors, this is unnecessary, and most of the time it causes waste of water resources. For example: the user who lives on the ground floor often turns on the tap, and the water will flow down like a spray, and the water will be splashed all over the body at the same time. According to incomplete statistics from netizens, 144,000 tons of water resources are wasted every day in my country due to excessive water flow. [0003] At present, there are many devices to reduce the flow rate on the market. The traditional ones are like a faucet wrapped in a towel, and the hygiene problem cannot be ignored; the advan...

Problems solved by technology

[0003] At present, there are many devices on the market to reduce the flow rate. The traditional ones are like a faucet wrapped in a towel, and the hygiene problem cannot be ignored; the advanced ones are controlled by computers and have a high level of technology, which is difficult to popularize and wastes resources.

There are similar products on the market, but their working principle is to use the propeller to adjust the speed. This method will increase the speed of the propeller when the water flow rate is higher. This adjustment method can only relatively reduce the water flow rate. The water flow rate cannot be fundamentally controlled within a certain stable range; it is still very limited in terms of resource conservation
