Abstract

The utility model relates to a wearless magnetic controlled valve, which mainly overcomes the defects that a screw of a valve of the rear of a water meter can be worn easily, and the water leaking phenomenon can occur easily. The utility model comprises a valve body and a water control mechanism, wherein, the lower part of the water control mechanism is fastened with a disk-shaped water stop rubber through a water stop rubber bracket, the disk-shaped water stop rubber is provided with a water inlet and a water outlet with different diameters, a sliding iron core is arranged above the water stop rubber bracket through an iron core casing, and the lower part of the water stop rubber bracket is fastened with a water stop rubber cap; a supporting spring is arranged above the sliding iron core, the outer side of the iron core casing is provided with a handle, and the lower part in the handle is provided with a special magnet. The utility model has the advantages of zero wear, strong water control capacity, no leakage, and water resource saving.

Description

There is not the wearing and tearing magnetic control valve

The utility model relates to the switch gear of tap water, the nothing wearing and tearing magnetic control valve of particularly a kind of water meter rear end.

At present, what China's tap water adopted mostly is that the screw type valve is made switch, and there is more drawback in this valve, valve rod as screw type is easy to wear, and the easily infiltration of screw rod upper end causes the pass valve not tight, thereby long-term percolating water not only causes a large amount of wastes of water resources, has also increased user's economic burden.

The purpose of this utility model be to provide a kind of simple and reasonable, do not have wearing and tearing, a stronger magnetic control valve of control outlet capacity.

The purpose of this utility model is achieved in that it comprises valve body and draining machine structure, the bottom of draining machine structure is to be interlockingly connected by water stop rubber support 2 and dish type rubber 3, it is provided with that two apertures equate advances, weep hole d1 and d2, the top of water stop rubber support 2 is by being provided with slip iron core 6 in the iron core overcoat 5, it is water stop rubber cap 4 of snapping down, the top of slip iron core 6 is provided with support spring 8, and the outside of iron core overcoat 5 is provided with switch knob 10, and the bottom is provided with special-purpose magnet 7 in the handle.

Advantage of the present utility model is the simple and reasonable of it, does not have wearing and tearing, and switch is fast light, and the control outlet capacity is strong, is not prone to percolating water, has saved water resources.

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

The structural representation of (closing) under Fig. 1 sealing state of the present utility model.

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

More than structure shown in the drawings be an embodiment of the present utility model.Among the figure, 1 is valve body; 2 is the rubber bearing support; 3 is the dish type water stop rubber, and its groove part is thinner, can stir up and down; 4 is the sealing rubber cap, the advancing of control B chamber, draining; 5 is the iron core overcoat, plays support spring 8 and iron core 6, and its center hole and iron core 6, spring 8 are slidingly matched; 6 are the slip iron core; 7 is magnet, and a control iron core advances, drainage; 8 is support spring, plays the supporting iron core; 9 is valve gap, its lower end and the nut screwed connection of valve body upper end; 10 is handle.This product can adopt the nontoxic pollution-free plastic production.

During the utility model work, when handle 10 was pressed, magnet 7 was downward thereupon, the top edge of iron core 6 is subjected to the effect of magnet 7 magnetic force, and iron core 6 upwards picks up, and makes water stop rubber cap 4 leave weep hole d2, at this moment, the water of water inlet d1 flows out from weep hole d2, makes the water budget of B chamber.At this moment, the pressure of water that enters water valve is greater than the hydraulic pressure of B chamber, and the edge of dish type water stop rubber 3 is upwards turned over (as shown in Figure 2), and valve body is opened.When handle 10 is upwards mentioned, magnet 7 makes progress thereupon, iron core 6 is subjected to the effect of magnet 7 magnetic force, and iron core 6 makes progress thereupon, when iron core 6 upper end pressure springs 8 rise to the limit, iron core 6 leaves magnet 7, spring 8 makes water stop rubber cap 4 seal water hole d2 with under iron core 6 bullets, makes the water that enters at the indoor generation pressure of B, make dish type rubber 2 resetted (as shown in Figure 1) by the pressure of water downwards, thereby reach the sealing purpose.

Claims

1, a kind of nothing wearing and tearing magnetic control valve, include valve body and draining machine structure, it is characterized in that: the bottom of draining machine structure is to be interlockingly connected by water stop rubber support (2) and dish type rubber (3), it is provided with that two apertures equate advances, weep hole d1 and d2, the top of water stop rubber support (2) is by being provided with slip iron core (6) in the iron core overcoat (5), it is a water stop rubber cap of snapping (4) down, the top of slip iron core (6) is provided with support spring (8), the outside of iron core overcoat (5) is provided with switch knob (10), and the bottom is provided with special-purpose magnet (7) in the handle.
