Quantitative self-closing valve

Abstract

The invention discloses a quantitative self-closing valve, which comprises a shell. A water outlet of the shell is provided with a water outlet pipe, the inner end of the water outlet pipe is providedwith a first water outlet and a second water outlet, a sealing cover is arranged at the second water outlet, a water baffle and a jacking rod connected with a lifting block are arranged on the lowerpart of the sealing cover, and the lifting block is provided with a gear structure; a rotating shaft and a worm wheel shaft are arranged in the shell, an impeller is mounted at the left end of the rotating shaft, and a worm structure is arranged at the right end of the rotating shaft; and a worm wheel and a transmission gear are mounted on the worm wheel shaft, the worm structure at the right endof the rotating shaft meshes with the worm wheel, and the transmission gear meshes with the gear structure on the lifting block. The shell is internally provided with the impeller, the worm wheel andthe transmission gear, a water flow rushes the impeller to move and drives the lifting block and the jacking rod through the worm wheel, a worm and a gear transmission structure to upwards push the sealing cover, the second water outlet is closed slowly, and thus quantitative water supplying is achieved. The quantitative self-closing valve is ingenious in conception, stable and reliable in work and wide in application range.

Description

technical field [0001] The invention relates to daily necessities, in particular, it provides a quantitative self-closing valve. Background technique [0002] When households use water or gas, they often forget to turn off the faucet or gas valve, wasting a lot of water or gas.
