Abstract
A water meter with high sensitivity is featured as connecting operation cavity to water inlet pipe through valve and check valve for maintaining pressure when water is leaked from water outlet and then moving piston towards right to push impact block for moving linkage mechanism towards right, pushing switch handle to move towards right by linkage mechanism for switching over valve set quickly as closing a valve quickly and opening another two valves quickly for compressing meter and contact.
Description
Technical field
The present invention relates to a kind of high sensitivity water meter.
Background technology
The energy source of the water meter counter of commonly using is in the amount of flow of water, and water meter is under normal discharge, and metering is correct, as turning down discharge, during to fine rule flow or drip amount, water meter does not rotate substantially, water meter is big more, and this phenomenon is serious more, does not reach the requirement of accurate metering.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, and a kind of high sensitivity water meter is provided.
Technical scheme of the present invention is, a kind of high sensitivity water meter, it is characterized in that: it comprises cylinder body and piston, and the piston two ends are provided with Impactor, and Impactor is connected with interlinked mechanism, trace is fixed on the housing, water inlet pipe is communicated with cylinder body respectively with rising pipe, and water inlet pipe is equipped with two valves, and rising pipe is equipped with two valves, four valves of switch block control, and with the interlinked mechanism interlock.
Described cylinder body cylinder mouth is a rubber closure.
Described shift bar one side is equipped with counter, and there is spring device the lower end.
The present invention has following advantage: improves the sensitivity of water meter, reduces cost, and simple in structure.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
See also figure, a kind of high sensitivity water meter, it comprises cylinder body 27 and piston 10, water inlet pipe 22 is communicated with cylinder body respectively with rising pipe 23, water inlet pipe 22 is equipped with two valves 1,2, rising pipe 23 is equipped with two valves 3,4, at cylinder body cylinder mouth rubber closure 24 is arranged, the reference mark of four valve 1-4 all concentrates on the valve member 20, when water is gone out by valve 3 and water delivering orifice 6 water clocks in the working chamber 8, pressure descends, working chamber 9 is connected with source not by valve 1 and non-return valve 5 and water inlet pipe 7, pressure can not descend, and piston 10 is pushed to 8 ends under the pressure differential effect, after working chamber 8 is squeezed, pressure recovers, piston 10 is along with the trickle drip of rising pipe 6 ends little by little is pushed to the right, and after piston was answered back to Impactor 11, interlinked mechanism 12 moved right, the upper end of shift bar 13 is pushed to right-hand, the lower end of valve member shift bar 13 is a cam, under 15 effects of fulcrum screw, in the first half term of cam, by spring cup 16 compression springs 14, slip over half way, spring 14 releases energy the acceleration switch handle anglec of rotation by spring cup 16 to cam, valve member is switched rapidly, valve 1,3 are closed rapidly, valve 2,4 are opened rapidly, and counter 17 and contact are compressed.
Claims (3)
