Description
Technical field
The utility model relates to the component of cistern, specifically be meant be used for cistern have the inlet valve of auto-lock function to prevent to continue to leak.
Background technique
The principle of cistern inlet valve is to utilize the interlock of keg float and valve plug to control the keying of inlet valve, when the water level in the water tank rises to certain altitude, keg float rises under the water floating function, ordering about piston holds out against on water intake, make into that water ends, after the drain valve draining of water tank, keg float falls, piston is pulled away from water intake, begins water inlet.
This shows that in the prior art, the keying and the water level in the water tank of inlet valve are closely connected together, as long as the water level in the water tank reduces, inlet valve will be opened, and water filling in the water tank makes the water level in the water tank can remain on certain altitude automatically.This has just caused following problem: when toilet did not use for a long time, the trace of drain valve leaked and causes drawdown, and also correspondingly water filling in water tank of inlet valve, thereby the lasting for a long time trace of water tank is leaked, cause a large amount of wastes of water resources.
The model utility content
The utility model provides a kind of inlet valve with self-locking mechanism, and its main purpose is to overcome existing cistern under long-term obsolete situation, and can continue trace and leak, thus the shortcoming that causes great lot of water resources to waste.
The utility model adopts following technological scheme: a kind of inlet valve with self-locking mechanism, comprise the inlet valve body and can slide up and down to be sheathed on this keg float external and of inlet valve by being connected on a double-action mechanism and the inlet valve body, it is characterized in that: described keg float end face be provided with both sides oblique that extend down, can its bight be the L shaped hasp that the center swings up and down, inlet valve body sidewall is provided with the locating tooth that matches with this L shaped hasp inner side edge end; Keg float is provided with a little keg float movable up and down and a push rod movable up and down, the upper end portion of this push rod is corresponding to the below of the outer side of L shaped hasp, the bottom of keg float is provided with the fork that two ends can swing up and down, two swinging ends of this fork are articulated in the underpart of little keg float and the underpart of push rod respectively, and the underpart of this push rod also is connected to the spanner of cistern drain valve by a chain.
Under normal situation about using, the working principle of the principle of this scheme and normal discharge valve is similar, and promptly water level rises to certain altitude and stops into water, and drawdown to certain position begins to intake.When the spanner of pressing the cistern drain valve makes water tank carry out draining, chain upwards spurs aforementioned push rod simultaneously, the make progress outer side of the L shaped hasp of jack-up of push rod, make its inner end to lower swing, disengaging cooperates with inlet valve base side parietal tooth, thereby keg float can be fallen along with the decline of water level in the water tank, so that opening, inlet valve realizes water inlet, and when water level raise, keg float raise along with the rising of water level, drove inlet valve and closed, and, little keg float also rises along with water level, by fork push rod is pulled down, thereby the inner end of L shaped hasp is snapped on the tooth of inlet valve body sidewall.When toilet did not use for a long time, the drain valve trace leaked, and water level slowly descends in the water tank, but under the effect of L shaped hasp, keg float can not fall, thereby inlet valve can not open, and only was with original water light leak in the water tank, can not cause a large amount of wastes.When reusing toilet, press the spanner of drain valve, as mentioned above, chain upwards spurs aforementioned push rod, and the make progress outer side of the L shaped hasp of jack-up of push rod makes its inner end to lower swing, disengaging cooperates with inlet valve base side parietal tooth, thereby keg float is fallen, and realizes water inlet so that inlet valve is opened.
Aforementioned a kind of inlet valve with self-locking mechanism, its double-action mechanism comprises a swing arm and a pull bar, the inlet valve bodies top can be located in these swing arm two ends with swinging up and down, the upper end portion of one end and pull bar articulates, the other end extends to water intake top in the inlet valve body top, described keg float side is provided with a link arm that outwards protrudes out, and the outer end of this link arm is connected with described pull bar underpart.
Further, described little keg float is located on the little fly rod, and the upper end portion of this little fly rod is arranged in the middle part of described link arm movably, and described push rod can slide up and down to be arranged in the described keg float.
Further, described keg float bottom is provided with two lugs in the outer part, the middle part of described fork is articulated between this two lug, and the two end part of described fork are provided with the pivot connected slot that extends vertically, and the underpart of described little fly rod and the underpart of push rod are hubbed at respectively in this two pivot connected slot.
In addition, the relative position relation of little keg float, push rod and keg float can also can be located at below in the described keg float for: described little keg float up and downly, and described push rod can slide up and down to be arranged in the middle part of described link arm.
Further, described keg float bottom is provided with two lugs in the outer part, the middle part of described fork is articulated between this two lug, described little keg float bottom is provided with a pivot connected slot, the inner end of this fork is articulated in this pivot connected slot, and the outer end of this fork is provided with one along its axially extended pivot connected slot, and the underpart of described push rod is articulated in this pivot connected slot.
Aforementioned a kind of inlet valve with self-locking mechanism, its keg float end face is provided with a lug, and a pivot connected slot that extends is downwards formed on this lug top, and the bight of described L shaped hasp is articulated in this pivot connected slot.
In sum, compare, the utlity model has following advantage: when not using toilet for a long time with prior art, its inlet valve has auto-lock function, can not continue to leak because of lasting water inlet causes, and, normal when using toilet, but its inlet valve automatic unlocking does not again influence water inlet.
