Abstract
A drip-proof water meter relates to a home-use water meter. Considering that the prior water meter, working by using water to rotate an impeller to take a count, has a deficiency of failing to measure a micro-flow quantity, a simple-structured drip-proof water meter with a switchable micro-flow tube arranged in the pipe of a water meter inflow end is proposed. The technical proposal is that a valve core (1) is arranged at the inflow end of the water meter (10). A filter casing (2) is provided outside one end face water-inlet (7) of the valve core (1), and an interchanger (4) with a rotating reed is arranged at the other head face. The water-inlet (7) is communicated with a micro-flow tube (3). A big spring (5) is sleeved outside a valve seat (11). One end of the big spring (5) is pressed against the valve core (1). A small spring (6) is provided inside the valve seat (11), and one end of the small spring (6) is pressed against a driving and reversing rod (8).
Description
One, technical field
The utility model relates to domestic meter, especially a kind of anti-leakage water meter.
Two, background technology
Existing domestic meter adopts water directly to impact impeller, and impeller rotation and the driven gear case is counted physical construction because the limitation of project organization can only the normal stream amount measure, and exists the deficiency of incompetent metering to micrometeor (drip, leak).At number of patent application 93201747.9, " a kind of liquid crystal display electron water meter " disclosed, still exist above-mentioned weak point.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, is provided with the anti-leakage water meter of the microflow channels that can open and close in the water meter water inlet end pipe.
The technical scheme that the purpose of this utility model adopted is, comprise the water meter that has impeller, it is characterized in that being equipped with spool in the entrance point of water meter, there are filter mantle, other end to have band to rotate the interchanger of reed outside the one end face inlet opening of spool, the inlet opening is communicated with microflow channels, and valve seat is with big spring outward, and an end of big spring withstands spool, little spring is arranged in the valve seat, and an end of little spring withstands moving rod.
The utility model, the endpiece of microflow channels is aimed at impeller.
The utility model when big flood flows to fashionablely, is pushed spool open, and water is directly entered in the water meter, impulsion impeller counting, and the rotation reed of interchanger cuts out microflow channels under the effect of the top of moving rod and rotate simultaneously, and microflow channels is anhydrous to be passed through; If when the water trace entered, big spring resetted, withstand spool and close the major path water inlet, the rotation reed of interchanger is thrown off the top of moving rod simultaneously, opens the microflow channels passage, and the miniflow water gaging enters microflow channels by filter mantle, inlet opening, directly impacts the impeller counting.
The utility model, have simple and compact for structure, characteristics such as fabrication and installation are convenient, and effect is obvious.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Among the figure: the 8-moving rod 9-impeller 10-water meter 11-valve seat of 1-spool 2-filter mantle 3-microflow channels 4-interchanger 5-big spring 6-little spring 7-inlet opening
Five, embodiment
As shown in drawings, have in the entrance point of water meter 10 of impeller 9 and be equipped with spool 1, an end face inlet opening 7 that has the spool 1 of filter mantle 2 is communicated with microflow channels 3, the other end has band to rotate the interchanger 4 of reed, the valve seat 11 outer big springs 5 that are with, one end of big spring 5 withstands spool 1, little spring 6 is arranged in the valve seat 11, and an end of little spring 6 has moving rod 8.
Claims (2)
1, a kind of anti-leakage water meter, comprise the water meter (10) that has impeller (9), it is characterized in that being equipped with spool (1) in the entrance point of water meter (10), one end face inlet opening (7) of spool (1) is outer to have filter mantle (2), other end to have band to rotate the interchanger (4) of reed, inlet opening (7) is communicated with microflow channels (3), and valve seat (11) is outer to be with big spring (5), and an end of big spring (5) withstands spool (1), little spring (6) is arranged in the valve seat (11), and an end of little spring (6) withstands moving rod (8).
2, a kind of anti-leakage water meter according to claim 1 is characterized in that the endpiece of microflow channels (3) is aimed at impeller (9).
