Self-adaptive throttling faucet

Abstract

The invention discloses a self-adaptive throttling faucet which is used for opening or closing water tail end flow of a water supply network. The self-adaptive throttling faucet mainly comprises a fixed sleeve (1), a spring (2), a sliding sleeve (3), a resistance cone (4) and a faucet (8). The self-adaptive throttling faucet has the main advantages that under the action of water pressure within a preset range, the faucet automatically maintains a stable outflow, so that throttling and water conservation are achieved.

Description

technical field [0001] The invention relates to a throttling faucet, in particular to an adaptive throttling faucet, which is composed of a throttling mechanism and a faucet. It is used to open and close the flow of water at the end of the water supply network. Background technique [0002] Faucets are widely used at the water end of the water supply network and serve thousands of households in urban and rural areas. According to the "Code for Design of Water Supply and Drainage for Buildings" (GB50015-2003), when the applied water pressure is 0.05MPa, the rated flow rate of the faucet is 9 liters / min. But in fact, the acting water pressure far exceeds 0.05MPa, most of which are above 0.2MPa. Taking 0.2MPa as an example, when using an ordinary faucet, the flow rate reaches above 14 liters / min, an increase of more than 44%. However, the increase greatly exceeds the specification requirements, and this overpressure and overflow will cause a lot of waste during use. Not onl...

Taking 0.2MPa as an example, when using an ordinary faucet, the flow rate reaches above 14 liters / min, an increase of more than 44%. However, the increase greatly exceeds the specification requirements, and this overpressure and superflow will cause a lot of waste during use.
