Abstract
The utility model relates to a water meter, which is composed of a meter casing, a machine core, meter glass, etc. The machine core is composed of a digital counting device which is composed of a water meter gear transmission mechanism, an indicating counting mechanism matched with the water meter gear transmission mechanism, a meter dial, etc.; the indicating counting mechanism is encapsulated inside a character wheel box by liquid; the meter dial of the water meter adopts vacuum encapsulation, and liquid is arranged inside the meter dial; the gear transmission mechanism is an integral element; a body of a transmission gear set of different speed regulation is arranged inside a pair of clamping plates. The utility model has the advantages of compact structure, convenient assemblage, reading keeping clear permanently, etc.
Description
The utility model relates to a kind of counting assembly of tap water flow.
Conventional water meter has wet-type meter and dry-type meter.Wet-type meter is easy to make precipitation of scales on the character wheel surface, and influences meter reading because its counting mechanism all is immersed in the tap water; Though and its counter of dry-type meter is isolated with tap water, reading is not contaminated, but by the transmission of pair of magnetic element, the time is long slightly, and the iron rust in the pipeline is adsorbed on around the magnet steel, accumulate over a long period, magnet steel is tightly surrounded, influence the transmission sensitivity, and magnetic induction density weakens gradually, reduce transmission power, the accuracy of influence metering.Therefore, at above-mentioned situation, scientific and technical personnel have done continuous improvement to water meter, as Chinese patent 98213622.6 disclosed a kind of " liquid sealed vane wheel water meter ", its counting mechanism is an independently monoblock type packaged unit, it is encapsulated in the character wheel box with liquid, thereby has solved the problem that character wheel is polluted by water, and makes accurate measurement.But this water meter is because structural restriction, exist easy to assembly, scale dish poor sealing, easily immersion influences the defective of reading.
The purpose of this utility model is to provide at the defective of prior art a kind of compact conformation, easy to assembly, reading to keep forever liquid sealed vane wheel water meter clearly.
Goal of the invention of the present utility model is achieved by the following scheme: this water meter comprises impeller, the leaf box, watchcase, movement and watch glass, wherein movement is by water meter gear drive and the indication counter mechanism that connects with it, the digital counting device that scale dish etc. are formed constitutes, indication counter mechanism is encapsulated in the character wheel box with liquid, character wheel transmits axis hole and seals with the O RunddichtringO, gear train is through gear set, worm screw, the worm gear drives digit wheel, wherein character wheel box and transparent cover are as one, the scale dish is encapsulated between watch glass and the transparent cover with liquid vacuum, with glass seal and the sealing of 0 type circle.
The driving gear set main body that described gear drive can be different speed changes is loaded in the secondary upper and lower clamping plate, and the supporting plate bottom lower plate is fixed, lower plate after being connected and supporting plate have one to make transition gear on the impeller pass center pit with the driving gear set gearing mesh, and cleat body connects with transparent cover.
Described clamping plate and character wheel box after connecting with transparent cover can integral body place in the tooth box, and a center pit that is used for fixing transition gear on the impeller is arranged at tooth box bottom.
Described upper and lower clamping plate and transparent cover and tooth box all can the buckle form be combined into one, and constitute dismountable connection.
Scale dish of the present utility model adopts Vacuum Package, can keep reading forever clear; The gear drive group main body that different speed are become is loaded in the auxiliary splint, is connected with impeller by transition gear again, has compact conformation, easy to assembly, highly versatile characteristics.
