Abstract
The utility model discloses a time-delay valve which comprises a valve body that is provided with a water inlet and a water outlet; an inner cavity of the valve body is provided with a first clapboard which is provided with a through hole; the inner cavity of the valve body is divided into a water inlet cavity and a water outlet cavity by the first clapboard, wherein the water inlet cavity and the water outlet cavity are communicated with each other by the through hole; the water inlet cavity is internally provided with a valve seat which is internally provided with a second clapboard; the valve seat is divided into a water inlet chamber and a valve core chamber by the second clapboard; the valve core chamber is internally provided with a valve core, and a spring is arranged between the valve core and the second clapboard; the through hole on the first clapboard can be plugged by the valve core; the water inlet chamber of the valve seat is communicated with the water inlet; the side wall of the water inlet chamber is provided with a water hole communicated with the water inlet cavity; the water outlet cavity is internally provided with an ejector rob leaning against the valve core; and the second clapboard is provided with a water inlet hole communicating the water inlet chamber and the valve core chamber. The external water pressure and the spring have synergistic effect when the time-delay valve resets, so that the resetting acting force of the valve core is increased, the resetting time of the valve core is reduced, the water quantity used for washing for once is reduced, and the time-delay valve is beneficial to saving water.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of time-delay flushing valve.
Background technique
The time-delay valve that tradition is used to wash comprises valve body, valve body is provided with water intake and water outlet, body cavity is provided with first dividing plate, first dividing plate is provided with through hole, first dividing plate is separated into water-inlet cavity and water chamber with body cavity, water-inlet cavity and water chamber are communicated with by through hole, valve seat is installed in the water-inlet cavity, be provided with second partition in the valve seat, second partition is separated into intake chamber and valve core chamber with valve seat, spool is installed in the valve core chamber, between spool and the second partition spring is installed, but the through hole on the spool shutoff dividing plate, and the intake chamber of valve seat communicates with water intake, the sidewall of intake chamber is provided with the water hole that water-inlet cavity is communicated with, but the push rod of contact spool is installed in the water chamber.The resetting of tradition time-delay valve spool is to realize the opening time of the size decision spool of spring force, thereby decision wash water amount by the elastic force of spring.Because the elastic force of spring is smaller usually, and spring can decay gradually at the long-term back elastic force that uses, so the resetting time of spool is longer, and the once flushing water yield is bigger.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of reduces the valve core reset time, the time-delay valve of the reduction once flushing water yield.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of time-delay valve, comprise valve body, valve body is provided with water intake and water outlet, body cavity is provided with first dividing plate, first dividing plate is provided with through hole, first dividing plate is separated into water-inlet cavity and water chamber with body cavity, water-inlet cavity and water chamber are communicated with by through hole, valve seat is installed in the water-inlet cavity, it is characterized in that being provided with in the valve seat second partition, second partition is separated into intake chamber and valve core chamber with valve seat, and spool is installed in the valve core chamber, between spool and the second partition spring is installed, but the through hole on spool shutoff first dividing plate, the intake chamber of valve seat communicates with water intake, and the sidewall of intake chamber is provided with the water hole that is communicated with water-inlet cavity, but the push rod of contact spool is installed in the water chamber, and described second partition is provided with the water inlet that is communicated with intake chamber and valve core chamber.
As the utility model improvement of the technical scheme, water outlet is equipped with reducer, and the reducer inwall is provided with the annular projection of taper.
The beneficial effects of the utility model are: the utility model is provided with second partition in valve seat, second partition is separated into intake chamber and valve core chamber with valve seat, second partition is provided with the water inlet that is communicated with intake chamber and valve core chamber, spool is external water pressure and spring synergy when resetting, thereby strengthened the active force of valve core reset, reduced the valve core reset time, reduced the once flushing water yield, help water saving, facts have proved, the each total water amount of the utility model is the 1.2-2.0 liter, economizes on water more than 80% than traditional time-delay valve.
Description of drawings
