Abstract
The utility model relates to an anti-drip water meter, comprising a meter head and an inlet tube, wherein the meter head comprises a meter case and a meter core, the middle part of the inlet tube is provided with a round tube junction with an internal diameter greater than that of the inlet tube orifice, the inner of the inlet tube is also provided with an elastic piston structure; the elastic piston structure comprises a supporting disk arranged in the inlet tube, a slide shaft fixed in the middle part of the supporting disk, a piston sleeved on the slide shaft, a spring for connecting the piston and the supporting disk and an anti-creep block fixed on the end of the slide shaft; the surface of the supporting disk is provided with circular holes; the spring is made of steel wire wrapped with waterproof plastic. According to the utility model, the elastic piston structure and the round tube junction are in cooperation to form a waterway switch, and only when two ends of the piston encounter large pressure difference the current can pass through, which can prevent minimal water flow; the anti-drip water meter possess anti-drip function and, can raise water meter performance and minimize water resource waste, thus is energy saving and environmental protection.
Description
Technical field
The utility model relates to a kind of water meter, especially a kind of anti-leakage water meter.
Background technology
At present, except disposing requisite water swivel, also is furnished with water meter on family's running water pipe commonly used.The common structure of water meter is made of a watchcase and watch core, current enter watch core from watchcase one end, drive propeller runner and rotate, and current flow away from the watch core other end again, the propeller runner that rotates drives the note amount device metering of watch core top, and discharge what can write down under the pointer that rotates; Propeller runner at the small situation following table in-core of aquifer yield does not rotate, if just record is less than discharge under the situation of water clock for water swivel, water supply plant causes damage.
The utility model content
The purpose of this utility model just is the deficiency at prior art, a kind of anti-leakage water meter is provided, it has the antidrip function, and the water swivel that is installed on the running water pipe is no longer leaked, thereby has solved running water pipe in the propeller runner of the small situation following table of aquifer yield in-core rotational problems not.
Realize that the technical scheme that the utility model purpose is adopted is: a kind of anti-leakage water meter, it comprises a gauge outfit and an inlet tube, and gauge outfit comprises watchcase and watch core, and inlet tube and gauge outfit are connected, and it is characterized in that:
Described inlet tube, its middle part is provided with a circular duct ligation, and this circle duct ligation internal diameter also is provided with an elastic piston structure greater than the inlet tube spout diameter in the inlet tube;
Described elastic piston structure, it comprises the support disk that is arranged in the inlet tube, is fixed in the slide-bar that supports the disk middle part, the spring that is connected between the piston that is placed in slide-bar, piston and the support disk, the anti-drop block that is fixed in the slide-bar end;
Described support disk, its surface is provided with circular hole, and it is made by rigid plastic;
Described anti-drop block, it is made by the stainless steel disk;
Described spring, it is made by steel wire, is enclosed with waterproof plastic on the steel wire.
The utlity model has following beneficial effect: the elastic piston structure cooperates formation water route switch with circular duct ligation, current could pass through when there is big pressure differential at the piston two ends, can stop small current, has the antidrip function, the water meter performance can be improved, water resource waste can be reduced, energy-conserving and environment-protective.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. gauge outfit, 2. watch core, 3. inlet tube, 4. piston 5. supports disk, 6. slide-bar, 7. spring, 8. anti-drop block.
Embodiment
As shown in Figure 1, a kind of anti-leakage water meter, it comprises a gauge outfit 1 and an inlet tube 3, and gauge outfit comprises watchcase and watch core 2, and inlet tube 3 is connected with gauge outfit 1; Described inlet tube 3, its middle part is provided with a circular duct ligation, and this circle duct ligation internal diameter also is provided with an elastic piston structure greater than inlet tube 3 spout diameters in the inlet tube 3; Described elastic piston structure, it comprises the support disk 5 that is arranged in the inlet tube 3, the slide-bar 6 that is fixed in support disk 5 middle parts, the piston 4 that is placed in slide-bar 6, piston 4 and supports the spring 7 that is connected between the disk 5, the anti-drop block 8 that is fixed in slide-bar 6 ends; Described support disk 5, its surface is provided with circular hole, and it is made by rigid plastic, and it is used to support slide-bar 6; Described anti-drop block 8, it is made by the stainless steel disk, is used to prevent that piston 4 from coming off from slide-bar 6; Described spring 7, it is made by steel wire, is enclosed with waterproof plastic on the steel wire, prevents that steel wire from getting rusty.
Described elastic piston structure cooperates formation water route switch with circular duct ligation, current could pass through when there is big pressure differential at piston 4 two ends, can stop small current, thereby have solved general water meter indeterminable problem under water swivel water clock situation.Described piston 4 can be free to slide on slide-bar 6, when the water swivel of running water pipe is tightened, and the suffered pressure unanimity in piston 4 both sides, the displacement that piston 4 does not take place to the right at this moment stops at original state; When water swivel dripped or leak, it is strong that the suffered hydraulic pressure in piston 4 right sides is slightly less than left side hydraulic pressure by force, and the elastic force that piston 4 will overcome spring 7 moves to right slightly, it is static to reach stress balance point, this moment, piston 4 was in before the circular duct ligation, still blocked inlet tube 3, prevented further water clock; If turn on water swivel, the suffered hydraulic pressure good general in piston 4 right sides is strong much smaller than its left side hydraulic pressure, and the rapid compression spring 7 of piston 4 meetings this moment moves to right to the circular duct ligation of inlet tube 3, and the water route switch is opened, and tap water can normally pass through.
