Abstract

A fluid metering device which mostly comprises an enclosure, a panel, an intermediate, a bed, a metering indication mechanism, and a flow transmission machine. The flow flow transmission machine comprises at least an upper cover and a lower cover as well as a balance wheel that is inbuilt at middle. The upper cover and lower cover forms a flow channel which is communicated with a fluid access channel on the bed. The balance wheel is connected with an axial cylindrical gear, and driven by a group of gears to connect with a helical gear which is sheathed on a print wheel shaft at least, thereby connected with a flow indication mechanism which is constituted by a large print wheel, and a small pint wheel which is fitted on a gear rack by a stick of print wheel at least. The flow transmission machine inside the bed is firmly sealed to the space between the bed and the intermediate with an O type seal ring and a plurality of bolts by the bed and intermediate. The balance wheel inside the flow transmission machine is connected with an axial cylindrical gear by the matching of a finger and a shifting fork. The cylindrical gear is connected with a couple of driving gears, then outputs by the gear wheel shaft and connected by a pair of helical gears that are engaged each other. The invention has the advantages of the simple structure, the usableness, the accuracy requirement that can conform to the actual situation, the low cost of manufacture, the extensive application and the long performance life, etc.

Description

Apparatus for metering fluids

Technical field

The utility model relates to a kind of fluid flow and carry out, especially You flow metering display device as flow metering and device shown.

Background technology

In the prior art, the metering of discharge and display device applications are comparatively extensive, as water meter of family expenses etc.In daily life, also has other flow measurement device, as gas meter, measurement of hot water table or the like.Usually fluid flow device mainly is made up of shell, panel, traffic transport mechanism and metering indication mechanism etc., the flow of fluid by traffic transport mechanism after by metering indication mechanism metering and show, this metering indication mechanism is existing mechanical, also has electronic liquid crystal to show.And the composition of traffic transport mechanism is also because of purposes, the difference of institute's fluid measured and different, but the precision of fluid metering is high more, and it is just complicated more that mechanism forms, especially at the flowmeter of oil; The composition of opposite mechanism is simple more, and cost is just low more, and the precision of metering is just poor.

Summary of the invention

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and the apparatus for metering fluids that precision can realistic request for utilization.It mainly is made up of shell, panel, intermediate, base, metering indication mechanism, traffic transport mechanism, described traffic transport mechanism includes loam cake and lower cover and middle built-in escapement at least, loam cake and lower cover form the fluid passage and are connected with fluid access way on the base, escapement links to each other with an axial cylindrical gear, and link to each other with a pair of spiral gear that is nested with at least one print wheel shaft by one group of gear drive, thereby with link to each other with the flow indication mechanism that the small character wheel constitutes by the big character wheel that is installed on the tooth rest by a print wheel shaft at least.

Described base and intermediate tightly are sealed in the traffic transport mechanism in the base between base and the intermediate by O RunddichtringO and screw.

Escapement in the described traffic transport mechanism cooperates with shift fork by pointer and links to each other with the axial cylindrical gear, and this cylindrical gear links to each other with a pair of transmission gear afterwards to be exported by gear shaft and links to each other with a pair of intermeshing spiral gear.

Described wherein at least one spiral gear directly or indirectly links to each other with little print wheel shaft or big print wheel shaft, little print wheel shaft links to each other by at least one group of transmission gear with big print wheel shaft, and is separately installed with small character wheels and the big character wheel group that shows metering on little print wheel shaft and big print wheel shaft.

The utility model compared with prior art has simple in structurely, easy to use, and accuracy requirement can realistic use, and low cost of manufacture is widely used, characteristics such as long service life, and it is particularly useful for the flow metering demonstration etc. of oil.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: Fig. 1, shown in Figure 2, the utility model mainly are made up of shell 1, panel 2, intermediate 3, base 4, metering indication mechanism 5, traffic transport mechanism 6.Described traffic transport mechanism 6 includes loam cake 61 and lower cover 62 and middle built-in escapement 63 at least, sees shown in Figure 3; Loam cake 61 and lower cover 62 forms fluid passages 64 and is connected with fluid access way 41 on the base 4, escapement 63 links to each other with an axial cylindrical gear 65, and link to each other with a pair of spiral gear 52 that is nested with at least one print wheel shaft 51 by one group of gear drive 66, thereby with link to each other by being installed in the flow indication mechanism 5 that big character wheel and the small character wheel on the tooth rest 53 constitutes by a print wheel shaft 51 at least, escapement 63 in the traffic transport mechanism 6 is made circular motion under the effect of current, cooperate by pointer on the escapement and shift fork, circular motion is reached cylindrical gear 65, thereby motion is reached tooth rest 53, realize single metering and cummulative metering respectively.

Base 4 described in the utility model and intermediate 3 tightly are sealed in the traffic transport mechanism 6 in the base 4 between base 4 and the intermediate 3 by O RunddichtringO 42 and screw 43.Escapement 63 in the described traffic transport mechanism 6 cooperates with shift fork by pointer and links to each other with axial cylindrical gear 65, and this cylindrical gear 65 links to each other with a pair of transmission gear 66 afterwards to be exported by gear shaft and links to each other with a pair of intermeshing spiral gear 52.Described wherein at least one spiral gear directly or indirectly links to each other with small character wheel shaft 51 or big print wheel shaft, small character wheel shaft 51 links to each other by at least one group of transmission gear with big print wheel shaft, and on little print wheel shaft and big print wheel shaft, be separately installed with the small character wheels 54 and the big character wheel group 55 that show metering, the utility model reaches small character wheels 54 and big character wheel group 55 by the cooperation of gear with data on flows, thereby realizes that single metering and cummulative metering also show.
