A hydraulic time-delay self-closing water-saving faucet spool

Abstract

The invention discloses a hydraulically-delayed self-closed water-saving water faucet valve element which comprises a valve seat main body, a time regulating mechanism, a rotary type fast forward drive mechanism, a delay mechanism, a water inlet and stop mechanism and a water stop valve element; the time regulating mechanism fits to the fast forward drive mechanism; the rotary type fast forward drive mechanism fits to the delay mechanism; and the delay mechanism fits to the water inlet and stop mechanism. With the adoption of the structure, a spline type rotary sleeve is rotated, so that fast forward returning operation and opening-closing operation are realized; the delay mechanism is completely separated from the water stop mechanism, so that during use, influences of water pressure are avoided, closing is quick, a regulating function for delaying and self-closing time 3-60 seconds is internally set, and batch delay time is accurate.

Description

technical field [0001] The invention relates to a faucet valve core. Background technique [0002] With the aggravation of the water resource crisis and the deteriorating quality of the water environment, the available water resources for human beings will tend to be scarce, and it is imperative to save water. The mechanical time-delay self-closing faucet can reduce the waste of water such as not turning off the water, overtime water, etc., and does not consume other energy when using it, saving energy and water. It is an ideal terminal water appliance for human beings to save water. At present, there are two kinds of mechanical delay self-closing faucets on the market, push type and hand dial type. The hand dial type overcomes the technical defect that the push type cannot turn off the water at will, and realizes the automatic switch and the delayed self-closing function of forgetting to turn off the water. However, the manual time-delay self-closing faucet manufactured by...

AI Technical Summary

Problems solved by technology

[0003] ⑴The delay mechanism and the water stop mechanism still continue the push-type conjoined structure, so that the delay time is greatly affected by the water pressure. When the water pressure is high, the torque is too large, the switch feels poor, and it will cause slow closing and waste water resources

[0004] (2) The spool cannot be matched with ordinary ceramic quick-opening faucets, and the faucet body can only be manufactured independently, which has poor versatility, high cost, single product, and low product added value

[0005] (3) There is no external delay time adjustment function, and the delay and self-closing time consistency is poor during mass production, which affects the reliability of product quality
