Abstract

The utility model relates to a valve core isolated water tap, which belongs to the field of water heating devices. The utility model is composed of a decorative board, a hand wheel, a screw nut, a valve core, a pressing sleeve, a screw nut sleeve, a sealing gasket, a valve piece, a sealing ring and a connector. The utility model is characterized in that the concave-convex sealing gasket is arranged in the valve body of the utility model, the sealing gasket and the valve core are arranged on a coaxial line, are arranged on the lower part of the pressing sleeve, and are arranged on the position of the upper part of a water inlet cavity. The hand wheel is clockwise rotated, the concave-convex sealing gasket is lifted, and running water is flowed in via the water inlet cavity; the hand wheel is clockwise screwed, the concave-convex sealing gasket is descended, and the water inlet cavity is closed. The utility model has the advantages of compact structure, reasonable arrangement design, no leakage, etc.

Description

The isolated water tap of spool

The utility model relates to the hot-water heating devices field, is the isolated water tap of a kind of spool.

At present, the spool of the water tap inside in the hot-water heating device is directly to be connected with knob, closes or opens water tap and be by the combination of spool and valve body or separate and realize damming or discharging of water.The water tap of this structure is along with the increase of closing, opening number of times, and the micro-leakage of water is quotidian.

The purpose of this utility model is, provides a kind of spool isolated water tap, and spool directly is not connected with valve body, adopts spool and the isolated structure of gland, solving the problem that tap water leaks, and raising water tap working life of closing, opening.

Above-mentioned purpose is achieved in that in water tap inside gland is set, gland is set in spool, and place the inwall of valve body, gland and spool below are provided with and are the concave-convex shape sealing gasket, push down the pad edge at sealing gasket spill two ends by gland, inlay in the eyelet of people's spool lower end at the top of convex, opens or close all to move up and down by reverse thread belt movable valve plug, concave-convex shape sealing gasket in the handwheel, water-inlet cavity is in opens or block state.

The advantage of this structure is that technological scheme design is comparatively reasonable, and the actuator when water tap is closed is non-hard parts, replace with the sealing gasket of flexibility, and sealing gasket does not have the friction of turning to, and the flow of tap water is easy to regulate.

Referring now to above schematic representation, and in conjunction with the embodiments its feature is done further narration: the isolated water tap of spool is not have on the basis that isolates the spool water tap, carry out a kind of water tap of architecture advances, it is by decorative sheet 1, handwheel 2, nut 3, spool 4, gland 5, nut sleeve 6, sealing gasket 7, valve body 8, seal ring 9, connector 10 is formed, in valve body 8, be provided with and be cancavo-convex sealing gasket 7, sealing pad 7 is laid with spool 4 coaxial lines, place the top position of water-inlet cavity 11, the top of its convex is to be bumped in the eyelet of spool 4 lower ends, and the pad edge at spill two ends is the belows that place gland 5; Be provided with the guide pad 12 of disjunctor in spool 4, at the inwall of gland 5 guide ledges 13 be set, guide pad 12 is the guiding grooves that place between the boss 13; Feather key 14 is set on the circumference of gland 5, offers wall groove 15 on the inwall of valve body 8, this feather key 14 is to place among the wall groove 15.

Embodiment's (working principle):

Connecting tube is connected with the running water pipe joint during installation, unscrews handwheel after the connection, and water-inlet cavity 11 can be full of tap water.The outside thread of the internal thread of handwheel 2 and nut sleeve 6 is tightened and is one, the outside thread of valve body 8 upper end portions and the internal thread of nut 3 are also tightened and are one, they are all tightened with special tool, and armrest is moving can't implement that it is loosening, just seems easy and manually unscrew handwheel.When counterclockwise unscrewing handwheel, spool 4 drives and is cancavo-convex sealing gasket 7 risings, and tap water is just introduced from connecting tube, flows into through water-inlet cavity, screws handwheel to clockwise direction when closing, and is cancavo-convex sealing gasket and promptly blocks water-inlet cavity.Connector 10 is the links with running water filter, or be used for washing machine tap water supplying tube supporting link.
