Abstract
The utility model relates to a water steal-preventing device, in particular to a drip-preventing and water steal-preventing device for a watermeter. The device can avoid water steal due to watermeter reverse assembly or water tap drip, and adopts the technical scheme that a sleeve is fixedly connected to one end of the watermeter; the diameter of the sleeve is larger than that of a water pipe; a cylindrical mouse cage is arranged in the sleeve and is connected to one end of the watermeter; an arc-shaped gland bush is arranged at the top end of the cylindrical mouse cage; a rubber sleeve is arranged on the water pipe matched with the arc-shaped gland bush; and a spring is arranged between the tail end of the mouse cage and a step between the sleeve and the water pipe. The utility model has the effects that of simple structure and low manufacturing cost, and can effectively avoid the watermeter reverse assembly, the water dripping phenomenon and the small stream of water phenomenon.
Description
Technical field
The utility model relates to a kind of apparatus preventing water robbing, especially relates to a kind of drip water meter antidrip apparatus preventing water robbing of stolen water of anti-dress of water meter or water halter that utilizes.
Background technology
At present, there is defective clearly in the domestic water meter metering, drip for the water halter exactly or the metering of tiny current powerless, more malice is if the reversal connection water meter, its water meter is counter to be walked, and numerical value reduces, and causes user's water meter number and the merchant's that supplies water water meter number to produce difference, causing bad influence, also is to supply water to discuss the rather thing of headache.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and provide a kind of and can effectively prevent water meter reversal connection, dripping phenomenon, fine water flow phenomenon, and the low water meter antidrip apparatus preventing water robbing of cost of manufacture.
Its technical scheme is: at an end fixed connecting sleeve of water meter, the diameter of sleeve pipe is greater than the diameter of water pipe, the tubular mouse cage is set in the sleeve pipe, at an end that connects water meter, on the top of tubular mouse cage the arc sealing gasket is set, with on the water pipe that the arc sealing gasket cooperates rubber sleeve is set, be provided with spring between the step between the end of tubular mouse cage and sleeve pipe and water pipe.
Effect of the present utility model is simple in structure, and cost of manufacture is low, can effectively prevent the generation of water meter reversal connection, dripping phenomenon, fine water flow phenomenon.
Description of drawings
Accompanying drawing is the structural representation of present embodiment.
Embodiment:
With reference to accompanying drawing, present embodiment mainly is to be connected with water meter by joint 1, water pipe 2 is as water inlet pipe, and water pipe 8 is a rising pipe, the other end fixed connecting sleeve 4 of water pipe 2, the diameter of sleeve pipe 4 is greater than the diameter of water pipe 2, tubular mouse cage 6 is set in the sleeve pipe 4, and at the water inlet pipe end, the top of tubular mouse cage 6 is provided with arc sealing gasket 5, water pipe 2 tops that cooperate with arc sealing gasket 5 are provided with rubber sleeve 3, are provided with spring 7 between the step that the end of tubular mouse cage 6 and sleeve pipe 4 and water pipe are 8.
During normal water, the halter of fetching boiling water, tubular mouse cage 6 moves to the direction of arrow under the effect of hydraulic pressure, and sealing gasket 5 separates with rubber sleeve 3, and the water route is logical opens.
When the water halter is closed, the pressure of water and atmospheric pressure difference disappear, and under the effect of spring, sealing gasket 5 moves to rubber sleeve 3 places, are sealed and matched, and the water route disconnects; If it is close to allow the water halter be not closed completely, allow the water halter drip or when tiny current are arranged, offset pressure reduction because of spring 7 effects, sealing gasket 5 is sealed and matched with rubber sleeve 3, and the water route is obstructed, weeping can not occur.
Because of the utility model is fixedlyed connected with water meter, if the water meter reversal connection, this installs same reversal connection, and water pipe 8 is a water inlet pipe, water pipe 2 is a rising pipe, and under the effect of spring 7, the tubular mouse cage is pushed ahead, and sealing gasket 5 moves to rubber sleeve 3 places, be sealed and matched, the water route disconnects, the not water outlet of water halter.
