Abstract

The utility model relates to a cistern float ball type magnetic control automatic valve. The utility model mainly overcomes the defect that the water valve of the high-building cistern has unreasonable structure, easy water overtopping and water waste. The utility model comprises a valve body and a water control mechanism. The upper part of the water control mechanism is buckled by a water stopping rubber support frame and disc-shaped water stopping rubber. The water control mechanism is provided with a water inlet hole and a water draining hole which have same hole diameter. The lower part of the water stopping rubber support frame is provided with a sliding iron core through an iron core outer sleeve, and the upper part of the water stopping rubber support frame is provided with a water stopping sliding iron core rubber cap. The lower part of the sliding iron core is provided with an auxiliary spring. The exterior of the iron core outer sleeve is provided with a lifting rod, and the upper part of the iron core outer sleeve is provided with a magnet. The lower end of the lifting rod is connected with a floating ball through floating ball screw nuts.

Description

Cistern float type magnetic control self-acting valve

The utility model relates to the recloser of high building water tank, particularly a kind of cistern float type magnetic control self-acting valve.

At present, the inlet valve that uses of China's high building water tank mostly is the floating ball lever valve.There is more drawback in this valve.As in order to increase buoyancy, the lever that has is done very longly, and ball float is also very big.When the pressure of tap water is excessive, lever is crooked easily, the lever connecting pin is stressed easy to wear greatly, ball float bump case top cracky or distortion, the valve body water stop rubber is subjected to lever pressure yielding and by being cut brokenly, causes water valve to be not closed completely, thereby overflows water for a long time, not only cause waste, and increased user's economic burden.

The purpose of this utility model is to provide a kind of rational in infrastructure, stronger cistern float type magnetic control self-acting valve of water inlet sealing control ability.

The purpose of this utility model is achieved in that it includes valve body and draining machine structure, and the top of draining machine structure is to be interlockingly connected by water stop rubber support 10 and dish type water stop rubber 11, be provided with on it that two apertures equate advance, weep hole d1 and d2; The below of water stop rubber support 10 is provided with slip iron core 7 by iron core overcoat 4, a sealing slip of snapping iron core rubber cap 9 on it, the below of slip iron core 7 is provided with secondary spring 6, the outside of iron core overcoat 4 is provided with lifting bar 3, the top of lifting bar 3 is provided with magnet 8, and the lower end of lifting bar 3 joins by ball float nut 2 and ball float 1.

Advantage of the present utility model is reasonable in design, and the control outlet capacity is stronger, can prevent preferably that the water in the water tank is excessive, thereby can protect water resources, alleviates user's economic burden.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of the utility model under the sealing state.

Fig. 2 is the structural representation of the utility model under the water inlet state.

More than structure shown in the drawings be exactly an embodiment of the present utility model.Among the figure, 1 is can be with water level rising or the ball float that descends; 2 for being welded on the nut on the ball float: 3 are lifting bar, its lower end and nut screwed connection; 4 is the iron core overcoat, plays supporting iron core 7, and its center hole and iron core are slidingly matched, and the top edge of iron core overcoat is connected the pressure of supporting sleeve 5 screw threads and the edge of dish type water stop rubber 11 seals; 5 for connecting supporting sleeve; 6 is secondary spring, plays auxiliary iron core 7; 7 are the slip iron core; 8 is controlling magnet; Draining slip iron core rubber cap till 9, the only draining of control B chamber; 10 is the water stop rubber support; 11 is the dish type water stop rubber, and its groove part is thinner, can stir downwards; 12 is valve body, is the shell of water valve.During the utility model work, when the water of water tank reaches ball float 1 certain altitude, lifting bar 3 magnet rise with the buoyancy of ball float, because iron core 7 is subjected to the magnet magnetic force, iron core 7 rises simultaneously and makes iron core rubber cap 9 seal sealing hole d2, make water that d1 enters at the indoor generation pressure of B, make dish type water stop rubber 11 upwards resetted (as shown in Figure 1) by the pressure of water, thereby reach the sealing purpose.When cistern water level descended, ball float 1 also descended from gravity with it, and lifting bar 3 drives magnet 8 and descends, and is subjected to the magnet magnetic force, and iron core 7 descends thereupon, and iron core rubber cap 9 leaves sealing hole d2, and at this moment the water of water inlet d1 flows out from sealing hole d2, makes the water budget of B chamber.At this moment the pressure that enters the water of water valve turns over (as shown in Figure 2) greater than the hydraulic pressure of B chamber downwards with the edge of dish type water stop rubber 11, makes water enter water tank.
