Problems solved by technology

[0002] Commonly used water meters include wet type and dry type. The wet type counting mechanism is completely immersed in water, and the reading plate is blurred and difficult to read due to the rust pollution in the pipeline. The rust in the dry type pipeline is adsorbed around the magnetic steel and tightly surrounds the magnetic steel. , affects the transmission sensitivity, the magnetic induction intensity gradually weakens, reduces the transmission force, and seriously affects the measurement accuracy

Embodiment Construction

[0010] As shown in Figure 1, a liquid-sealed water meter includes a watch case 6, a table cover, an impeller, a transmission mechanism 4, and an indicator mechanism. The indicator mechanism is encapsulated in a character wheel liquid seal box 1 with liquid, and the character wheel transmission shaft hole is used. The sealing ring is sealed, and a round shoulder 2 is added to the outer edge of the word wheel liquid seal box, and the inner liner is lined with a seal ring 3. The splint is provided with a matching installation socket hole for the word wheel liquid seal box, and it is movable and detachable. Gears with different speed changes The main body of the transmission part of the group can be commonly installed in a pair of splints 7. There is also a layer of splints 9 at the bottom of the splints to fix the filter gear 8 meshing with the impeller center gear 5. The transmission mechanism drives the digital wheel through the meshing of the worm and the gear. The splint passes...

Abstract

This invention relates to a liquid-sealed water meter including a meter shell, a cover, an impeller, a drive unit and an indication unit characterizing that said indication unit is sealed in a character-wheel liquid package box with liquid and the character-wheel delivery shaft hole is sealed with a sealing ring having the advantage of accurate counting, flexible drive, easy assembly and use.

Description

technical field [0001] The invention relates to a liquid-sealed water meter. Background technique [0002] Commonly used water meters include wet type and dry type. The wet type counting mechanism is completely immersed in water, and the reading plate is blurred and difficult to read due to the rust pollution in the pipeline. The rust in the dry type pipeline is adsorbed around the magnetic steel, tightly surrounding the magnetic steel. , affecting the transmission sensitivity, the magnetic induction intensity is gradually weakened, the transmission force is reduced, and the measurement accuracy is seriously affected. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide a liquid-sealed water meter. [0004] The technical solution of the present invention is a liquid-sealed water meter, which includes a watch case, a watch cover, an impeller, a transmission mechanism, and an indicating mechanism. The...
