Problems solved by technology

[0002] The commonly used water meter can perform accurate measurement under the premise of correct installation and use. However, when the water meter is used upside down, the water flow impels the impeller to reverse, driving the gear and the pointer to reverse, reducing the amount of water displayed by the water meter and causing measurement errors. It leads to a lot of waste of water resources and also provides an opportunity for water theft

Embodiment Construction

[0007] Please refer to the figure, a water meter with anti-theft water function. A backflow preventer 2 is sealed and installed inside the water meter inlet 1 near the dial. The backflow preventer 2 is composed of a sleeve 4, a screw 5 and a sealing sleeve 6. There is a boss 7 at the water inlet, and a water diversion hole 8 is arranged in the middle of the casing 4 along the circumferential direction. The casing 4 and the screw rod 5 are threaded, and the sealing sleeve 6 is set on the casing 4 to seal the water diversion hole. 8 and the boss 7, the needle backflow preventer is packed into the inner end of the water inlet of the water meter, and the rotating screw makes its top push against the diaphragm in the water meter.

Abstract

The invention relates to the water meter with the function of water thieving protection. The water meter intake close to one end of dial plate is hermetically set back flow stopper which is made up of casing pipe, screw, sealing sleeve. The casing pipe is close to water intake boss. Its middle part is set many water diversion ports. And it has thread fit with the screw. The sealing sleeve is hitched on the casing pipe to seal the water diversion port and boss. Needle back flow stopper is set at the end of the water meter intake. Screw is rotated to its top prop up the water meter cross slab. It has the advantages of combining metering, water thieving protection into a whole, avoiding water thieving, and saving water resources.

Description

technical field [0001] The invention relates to a water meter with anti-theft water function. Background technique [0002] The commonly used water meter can perform accurate measurement under the premise of correct installation and use. However, when the water meter is used upside down, the water flow impels the impeller to reverse, driving the gear and the pointer to reverse, reducing the amount of water displayed by the water meter and causing measurement errors. Cause a large amount of waste of water resources, also provide an opportunity for stealing water. Contents of the invention [0003] The object of the present invention is to overcome the above defects and provide a water meter with anti-theft function. [0004] The technical solution of the present invention is a water meter with anti-theft water function, which includes a water inlet, a water outlet, an impeller, a gear, a pointer and a dial, and is characterized in that: the end of the water inlet close to ...
