Abstract

The utility model relates to an automatic cutting off ceramic valve water tap, which is characterized in that the automatic cutting off ceramic valve water tap is driven by a draw rod (1); the draw rod is connected with the press handle (5) of the upper end of the centre hole of a water tap cover (4) by an inner frame (2) and an inner cap (3); springs (6) are arranged around the draw rod; the inner frame is fixed to a static ceramic chip (11); one side of the lower part of the draw rod is inlaid with a movable ceramic chip (16); appropriate pressure is exerted to the two ceramic chips by a rubber pad (18); the draw rod can move horizontally upwards along the guide way (17) of the inner frame when the press handle is wrenched by hands; the springs are pressed and the water tap can be opened; the springs can drive the draw rod recoil and the ceramic chips can recoil along the inner frame at the same time when the hands are away from the press handle, and the water can be closed automatically. The utility model is helpful for water saving and safety, and can be widely used on various cold and hot type drinking-water appliances, water purifiers and pure water machines.

Description

Automatically close the ceramic valve water tap

The utility model belongs to a kind of water tap of using ceramic valve.

At present, the mode that commercial ceramic valve water tap opens and closes turn 90 degrees or moves up and down for revolving, and is manually, can not close by self-return, in the use with economize on water unfavorable, when being used as when turning on the tap, unfavorable in safety.

The purpose of this utility model is to improve above-mentioned deficiency, solves self-closing device in the ceramic valve water tap, just water outlet when opening with hand, and ceramic valve is closed immediately automatically in the water tap when hand leaves, in order to water saving and safety.

Feature of the present utility model is to adopt pull bar transmission ceramic valve, pull bar passes through internal frame, inner cap links to each other in the top with by handle with the center hole of tap lid, spring is arranged around the pull bar, internal frame is stable ceramic piece and make it and leading water intake sealing fixedly, pull bar bottom one side studs with dynamic porcelain piece, and by suitable pressure between rubber cushion maintenance and stable ceramic piece, when with move down on hand by the time, by the pull bar transmission with dynamic porcelain piece upwards translation in internal frame is led, spring pressurized, tap is opened, when hand leave by the time, spring shackle rod return simultaneously dynamic porcelain piece is also led return along internal frame, tap is closed automatically.

Sectional view of the present utility model shown in the accompanying drawing specifies down in conjunction with the accompanying drawings:

As shown, pull bar (1) is by internal frame (2), inner cap (3) and the leading center hole that covers (4), limit it only at axial translation, link to each other on it with by (5), spring (6) is housed around the pull bar, internal frame is incomplete frustoconic shape, most of liner as leader shell (8) head (9), being close to its inwall, is plane (10) in leader shell water inlet position, and the sealing surface (12) of this plane and stable ceramic piece (11) matches, stable ceramic piece can be fixed on leading water intake (13), and execute certain side pressure and make seal ring (14) sealing on it.There is a rectangular water outlet (15) the stable ceramic piece below, covered and seal by dynamic porcelain piece (16) fully, cause tap to close, dynamic porcelain piece sealing surface (7) fits like a glove with the stable ceramic piece sealing surface and can be in the upper and lower translation slip in (17) of leading of internal frame plane (10) inboard, dynamic porcelain piece is set in pull bar bottom one side, can put into a rubber-like rubber cushion (18) at the pull bar at this place, impose the certain side pressure of dynamic porcelain piece, make, suitable pressure is arranged between stable ceramic piece, make when guaranteeing on pull bar underdrive and remain the lapping-in state between the sound ceramics, a circular inner cap (3) is arranged above internal frame, it is close to the tap head inwall seal ring (19) sealing, after tap lid (4) is tightened on leading going up, the tap lid compresses inner cap downwards, inner cap compresses internal frame downwards, when move with hand by the time, pull bar moves up, dynamic porcelain piece moves upward thereupon, spring compresses thereupon, but remaining part is motionless, stable ceramic piece water outlet (15) is come out, water just flows out, when hand leaves by handle, spring discharges, and lower position is led and got back to the downward return of shackle rod, dynamic porcelain piece just along internal frame, seal the stable ceramic piece water outlet, tap is closed automatically, between pull bar top inner cap and tap lid a seal ring (20) is arranged, and makes between pull bar and the tap lid water-tight, the utility model permanent durablely can be widely used on all kinds of cold and hot water drinking machines and water purifier with it, on the water purification machine.

Claims (3)

1. close the ceramic valve water tap automatically for one kind, it is characterized in that adopting pull bar (1) transmission ceramic valve, pull bar links to each other with the center hole of tap lid (4) in the top with by (5) by internal frame (2) inner cap (3), spring (6) is arranged around the pull bar, internal frame is stable ceramic piece (11) and make it pass through the sealing of seal ring (14) and leading water intake (13) fixedly, pull bar bottom one side studs with dynamic porcelain piece (16), and by the lapping-in between rubber cushion (18) maintenance and stable ceramic piece.

2. the ceramic valve water tap of closing automatically according to claim 1 is characterized in that having dynamic porcelain piece to lead (17) in the internal frame plane (10)

3. the ceramic valve water tap of closing automatically according to claim 1 is characterized in that fixedly internal frame of inner cap; Seal ring (19) is arranged between inner cap and tap head, between pull bar, inner cap and tap lid seal ring (20) is arranged.
