Description

Magnetic automatic water-filling on/off valve

Technical field

The present invention relates to a kind of in the automatic loading water water tank of equipment such as flush toilet on the magnetic automatic water-filling on/off valve controlled automatically of water.

Background technology

The automatic loading water water tank of traditional equipment such as flush toilet adopts float valve that its automatic loading water is controlled usually, its parts that cooperate with float valve change howsoever, the general lever construction of form everywhere that all be unable to do without, its reliable in action is poor, application life short, its reason mainly is: 1. no matter be lever direct press type or lever differential pressure type, lever all is to press against the current to close big valve port or little valve port, and the lever parts can damage gradually because of water attack like this; 2. the lever that is hanging, ball float are subjected to transportation easily and jolt and artificially damage, and lever has distortion slightly, will produce bigger water level deviation, 3. ball float for a long time in water tank swing cause the valve block wearing and tearing and leak; 4. switch is frequent, cistern water level fall a little some lever and floating valves will switch once, loss mechanical life; 5, the long-time use of ball float is leaked easily, gas leakage.

Summary of the invention

Technical problem to be solved by this invention is, a kind of simple in structure, long service life, magnetic automatic water-filling on/off valve that reliable in action is high are provided.

Magnetic automatic water-filling on/off valve of the present invention includes a valve body, inner core that is nested inside and outside valve body is provided with and urceolus, the inner chamber of inner core is the water chamber that is communicated with the delivery port of valve rear end, inner core is the intake antrum that is communicated with the water inlet of valve body front end with space between the urceolus, inner core and urceolus lower end are provided with opening, and the opening part in inner core and urceolus lower end is stamped an elastic rubber fitting; The edge of described elastic rubber fitting is pressed in the opening part of urceolus lower end by a gland in the outside, realizes the sealing that urceolus is inside and outside; The middle part of elastic rubber fitting can be moved because of elastic deformation is upper and lower, thereby seals or open the opening of inner core lower end; Also have first through hole and second through hole of diameter much smaller than the inner core opening diameter on the described elastic rubber fitting, described first through hole is over against the opening portion of inner core lower end, and described second through hole is over against the opening portion between inner core and the urceolus; Described gland is connected with a guide pin bushing, the guide pin bushing lower end closed, thus between the inboard of gland and guide pin bushing and elastic rubber fitting, form a chamber; Being provided with one in the guide pin bushing can be along the upper and lower mobile ejector pin of guide pin bushing, and the first above-mentioned through hole can be sealed in its upper end when moving on the ejector pin, and ejector pin is that ferrimagnet is made; Be with the permanent magnets of an annular in the guide pin bushing outside, permanent magnets be installed in one can floating drum with the cistern water level lifting on.

Described elastic rubber fitting soffit middle part also is lined with an outer liner that is connected with elastic rubber fitting, to improve the rigidity at elastic rubber fitting middle part.

Described ejector pin upper end is provided with a Rubber end, and ejector pin seals first through hole by Rubber end, the reliability when closing first through hole to improve ejector pin.

The present invention compares with the shutoff valve parts of traditional lever construction, need not the lever transmission, and is simple in structure, easy for installation, improved the reliable in action height, prolonged application life; Simultaneously, itself or utilize water feeding pressure improve to close water pressure, guaranteed to close the reliability of water, reduced because of closing the water waste that mouth of a river seepage causes.

Description of drawings

Fig. 1 is the structural representation of the embodiment of the invention.

Reference numeral comprises: valve body 1, inner core 2, urceolus 3, water chamber 4, intake antrum 5, elastic rubber fitting 6, gland 7, first through hole 8, second through hole 9, guide pin bushing 10, ejector pin 11, permanent magnets 12, floating drum 13, outer liner 14, block rubber 15.

The specific embodiment

In the embodiment of the invention course of work, the water inlet of valve body 1 by its front end is installed in the filling pipe end place in the water tank.As shown in the figure:

When cistern water level was low, floating drum 13 and permanent magnets 12 were in low level, and the ejector pins 11 in the guide pin bushing 10 fall, and make the conducting and do not produce pressure reduction about in the of 8 of first through hole on the elastic rubber fitting 6, thereby elastic rubber fitting can not seal the opening of inner core 2 lower ends.At this moment the current of intake antrum 2 press down the middle part of elastic rubber fitting 6, and intake antrum 2 and water chamber 3 are communicated at the opening part of inner core and urceolus lower end, and current enter on the water tank through the delivery port of water chamber 3 and valve rear end.

When the water level in the water tank rises when reaching a certain height gradually, floating drum 13 is also corresponding to attain to a high place, under the repulsion effect of the permanent magnets on the floating drum 12, ejector pin 11 in the guide pin bushing 10 rises, block rubber 15 by its upper end seals first through hole 8 on the elastic rubber fitting, the hydraulic pressure of intake antrum 2 is through producing big pressure in the cavity of second through hole 9 between gland 7 and elastic rubber fitting 6, make the upper and lower generation pressure reduction of elastic rubber fitting, thereby elastic rubber fitting is pressed on the opening part of inner core 2 lower ends, with the water chamber sealing, stop to go up water.Lining can improve the rigidity at elastic rubber fitting middle part at the outer liner 11 of elastic rubber fitting soffit, helps its reliable sealing to inner core.
