Abstract

The time-delay self-closing valve core is a time-delay self-closing valve core of water valve, belonging to the field of water-saving appliance technology, and mainly is formed from hand wheel, centre shaft, spring, upper valve, lower valve and ceramic core, etc. by turning hand wheel, the ceramic valve core can be opened, and when the hand wheel is released, the ceramic core can be automatically turned and closed, and the time-delay self-closing valve core can be substituted for ceramic quick-opening valve core so as to attain the goal of saving water resource.

Description

Time-delay self-closing valve core

Technical Field

The time-delay self-closing valve core is a water-saving device, and can automatically close the water valve in a time-delay manner.

Background

At present, the ceramic valve cores widely applied to the water faucet and the water valve in the society are basically quick-opening type, and must be manually opened and closed, and the waste of water resources is caused by untimely manual closing; in addition, the time-delay self-closing valve core widely applied to the water faucet and the water valve in the society is basically of a mechanical pressing type or an electronic valve type, the water outlet quantity is difficult to control, the structure is complex, the cost is high, and the waste of resources is caused.

Disclosure of Invention

The time-delay self-closing valve core can automatically close the water tap or the water valve in a time-delay manner, so that the aim of saving resources is fulfilled.

The time-delay self-closing valve core adopts the technical scheme that the time-delay self-closing valve core consists of a hand wheel, a central shaft, a spring, an upper valve, a lower valve, a ceramic core, a gland and a sealing gasket, the lower part of the upper valve and the upper part of the lower valve are respectively provided with three same spiral slope surface bodies, the inner side of each spiral slope surface body of the upper valve is provided with a cylindrical lock pin, the lock pin can be embedded into three slide ways of the central shaft to slide up and down, the spring is sleeved on the central shaft and fixed with the inner bottom part of the upper valve by the gland, the lower part of the central shaft is pulled out and inserted to drive the upper half part of the ceramic core to rotate, the hand wheel is rotated to drive the upper valve to rotate and move upwards, the spring is compressed, the central shaft drives the upper half part of the ceramic core to rotate under the pulling of the lock pin of the upper valve, a water hole of the upper half part of the ceramic core is communicated with a lower half water hole, after the hand wheel is released, the upper valve rotates under the counter-acting force of the spring and drives the central shaft to rotate, finally the upper ceramic core half is closed.

The time-delay self-closing valve core has the advantages that the valve core can be automatically closed in a time-delay manner after being opened, the water yield can be automatically controlled, the structure is simple, and the purpose of efficiently saving water is achieved.

The present invention will be further explained with reference to the drawings and examples.

Detailed Description

As shown in figure 1, the time-delay self-closing valve core is composed of a hand wheel 1, a middle shaft 9, a spring 3, an upper valve 4, a lower valve 10, a ceramic core 13, a gland 2 and a sealing gasket 13, wherein the hand wheel 1 is fixed on the upper part of the upper valve 4, the lower part of the upper valve 4 is provided with three same spiral slope bodies 7, the inner sides of the slope bodies 7 are respectively provided with a cylindrical lock pin 6, the lock pin 6 can be embedded into three slideways 5 of the middle shaft 9 to slide up and down, the upper valve 4 and the lower valve 10 both use the middle shaft 9 as a core, the upper part of the lower valve 10 is provided with three slope bodies 8 which are the same as the spiral slope bodies 7 of the upper valve, the spring 3 is sleeved on the middle shaft 9 and is fixed by the gland 2 and the inner bottom of the upper valve 4, the ceramic core is divided into an upper part and a lower part, the lower part of the middle shaft 9 is inserted and pulled out to drive the upper part of the ceramic core 13 to rotate, the lower part of the ceramic core 13 is fixed relative to the inner wall of the lower valve 10, a water hole of the ceramic core is communicated with the lower part after the upper part of the ceramic core rotates, the ceramic core is vertically fixed in the lower valve by the sealing gasket 12 in the lower valve, two water outlets 11 of a lower valve 10 are arranged at the top of the ceramic core, a water inlet 14 is arranged at the bottom of the lower valve 10, a hand wheel 1 is rotated to drive an upper valve 4 to rotate and move upwards, a spring 3 is compressed, a middle shaft 9 rotates under the stirring of a lock pin 6 and drives the upper half part of the ceramic core 13 to rotate, after the hand wheel 1 is loosened, the upper valve 4 rotates under the counter-acting force of the spring 3 and drives the middle shaft 9 to rotate, finally the upper half part of the ceramic core 13 is closed, water flows into the water outlet 11 from the water inlet 14 when the ceramic core 13 is opened, and the water outlet 11 does not discharge water when the ceramic core 13 is closed.

Claims
