Abstract
The utility model discloses an internal fluid drive device of a helical vane type small-diameter water meter. An upper impeller box and a lower impeller box which are matched are arranged in a shell, the upper impeller box and the lower impeller box are fixed through a connector arranged at the end of the shell, an impeller is arranged between the upper impeller box and the lower impeller box, an upper ejector pin and a lower ejector pin are perpendicularly fixed to the two ends of the center of the impeller, magnetic steel is fixed in the middle of the impeller, the upper end of the upper ejector pin is embedded into the upper impeller box, the lower end of the lower ejector pin is embedded into the lower impeller box, a circuit board is arranged on the lower impeller box, the lower impeller box is connected with a signal rod on the outer side of the shell, and the signal rod is sleeved with a signal rod sleeve. Water flows into the internal fluid drive device from the end of the shell and impacts the impeller directly through the upper impeller box front the front face, the impeller rotates, the water flows out from the connector through the lower impeller box, through the effect of a magnetic field, water flow drive signals are generated, and the lower impeller box is connected with the signal rod through the circuit board. The internal fluid drive device of the helical vane type small-diameter water meter can reduce the friction force between fluid and the meter, improve the sensitivity of the water meter, and meanwhile, prolong the service life of the meter and is simple in structure.
Description
Technical field
The utility model relates to water meter, relates in particular to a kind of internal flow gearing of small diameter watermeter of spiral type.
Background technology
The small diameter watermeter of civilian amount maximum, is all generally rotor water gauge in the market.Its principle of work is: current make it rotation from watchcase water inlet tangential impact impeller, and then by the revolution of gear reduction continuous recording impeller, thereby recorded stream is through the integrated flux of water meter.This kind of water meter after using for many years due to water in impurity stop up the factors such as monolateral impact impeller that form after filter screen, can make water meter under low discharge, walk slowly, and the phenomenon accelerating under flow greatly.And because current flow to movement from a direction, impact vane rotary, and easily cause this type of impeller movement eccentric wear, shorten water meter serviceable life, and sensitivity is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of internal flow gearing of small diameter watermeter of spiral type is provided.
The utility model solves the technical scheme that its technical matters adopts:
The internal flow gearing of the small diameter watermeter of spiral type comprises housing, upper impeller box, impeller, signal lever cover, wiring board, upper thimble, magnet steel, lower thimble, lower impeller box, joint, signal lever; In housing, be provided with the upper impeller box matching, lower impeller box, and the joint being provided with by shell end is fixed, between upper impeller box and lower impeller box, be provided with impeller, two ends, impeller center are vertically fixed with thimble, lower thimble, are fixed with magnet steel in the middle of impeller, and upper thimble upper end embeds upper impeller box, lower thimble bottom embeds lower impeller box, lower impeller box is provided with wiring board, and is connected with the signal lever of hull outside, and signal lever is provided with signal lever cover outward; Current flow into from shell end, through upper impeller box directly from frontal impact impeller, wheel rotation, current flow out from joint through lower impeller box, by the effect in magnet steel magnetic field, produce current actuating signal, via line plate is connected with signal lever.
Described impeller adopts propeller arrangement.
The utility model can reduce fluid and the friction force of table between tool, when improving the sensitivity of water meter, extends table tool serviceable life, simple in structure.The utility model is mainly used in vertical water meter device, realizes current and directly enters directly.
Accompanying drawing explanation
Fig. 1 is the structural representation of internal flow gearing of the small diameter watermeter of spiral type.
Embodiment
As shown in Figure 1, the internal flow gearing of the small diameter watermeter of spiral type comprises housing 1, upper impeller box 2, impeller 3, signal lever cover 4, wiring board 5, upper thimble 6, magnet steel 7, lower thimble 8, lower impeller box 9, joint 10, signal lever 11; In housing 1, be provided with the upper impeller box 2, the lower impeller box 9 that match, and the joint 10 being provided with by housing 1 end is fixing, between upper impeller box 2 and lower impeller box 9, be provided with impeller 3, impeller 3 two ends, center are vertically fixed with thimble 6, lower thimble 8, are fixed with magnet steel 7 in the middle of impeller 3, and upper thimble 6 upper ends embed upper impeller box 2, lower thimble 8 bottoms embed lower impeller box 9, lower impeller box 9 is provided with wiring board 5, and is connected with the signal lever 11 in housing 1 outside, the outer signal lever cover 4 that is provided with of signal lever 11; Current flow into from housing 1 end, and through upper impeller box 2, directly from frontal impact impeller 3, impeller 3 rotates, and current flow out from joint 10 through lower impeller box 9, by the effect in magnet steel 7 magnetic fields, produce current actuating signal, and via line plate 5 is connected with signal lever 11.Described impeller 3 adopts propeller arrangement.
The thimble of the utility model by impeller upper and lower surface by current directly from frontal impact impeller, thimble has not just had the side force that general water meter lateral inflow brings to impeller like this, can greatly reduce friction, make the acting on impeller of power maximum ratio of fluid motion, the motion state that reflects to greatest extent fluid, so because reduced the serviceable life of the prolongation table that wearing and tearing also can respond; And the design of the flow-guiding structure of water inlet position also can impel current symmetrical as much as possible when flowing through gearing impeller, reduced the uneven side force of bringing.
