The invention discloses a water-saving valve element. The water-saving valve element comprises a bottom cover, a shell, a first valve element, a second valve element, an upper end cover, a shift lever and a rotary shaft. The bottom cover is arranged at the bottom end of the shell. The upper end cover is arranged at the top end of the shell. The bottom cover seals up the bottom of the shell. The bottom of the bottom cover is provided with a first water inlet and a first water outlet. The first valve element and the second valve element are both arranged in a cavity. The bottom cover and the upper end cover conduct axial limiting on the first valve element and the second valve element. The first valve element is arranged at the upper end of the bottom cover. The upper end of the first valve element is provided with a second water inlet and a second water outlet. A partition board is arranged in the middle of the first valve element to separate the first water inlet from the second water outlet. The first water inlet communicates with the second water inlet. The second water outlet communicates with the first water outlet. The second valve element is arranged between the first valve element and the upper end cover. The lower end of the second valve element is provided with an end cap. The upper end of the second valve element is provided with a clamping groove. The lower end of the shift lever is clamped into the clamping groove. The shift lever is connected with the upper end cover through the rotary shaft. By adopting the water-saving valve element, bidirectional adjustment of the water volume can be realized.
Description
technical field [0001] The invention belongs to the technical field of water-saving equipment, in particular to a water-saving valve core. Background technique [0002] The key to choosing a faucet is a high-quality spool, which is one of the important parts used for control components in fluid systems such as faucets and valves. The spool is a valve part that realizes the basic functions of direction control, pressure control or flow control by means of its movement. Any on-off control of a faucet requires a spool. [0003] Most of the existing common faucets will be turned on to the maximum for use, no matter whether they need the maximum water flow or not, because it is very convenient to turn on the maximum water flow, and there are often cases where the faucet is forgotten to close, resulting in waste of water resources ; Although the infrared sensor switch faucet can be used and stopped in terms of water saving, the cost of the infrared sensor switch faucet is high, ...
