Abstract
The utility model discloses a digital bidirectional water meter capable of resetting. A common water meter can only carry out the one-way counting, which can not meet the requirement of a bidirectional counting occasion. The utility model is characterized in that the inner part of a meter case whose water inlet and water outlet are positioned at a same axis is provided with an impeller and a bidirectional precision regulating device. The impeller is connected with a counting device in a rigid way through a drive mechanism. A resetting device is arranged on the counting device. Therefore, the bidirectional metering and the precision regulation can be realized, the accumulated error can be cleared conveniently, and the requirements of the bidirectional metering (such as the water supply and the water drain of a domestic solar water heater), etc., can be met.
Description
The utility model relates to a kind of measuring apparatus, particularly a kind of water meter that is applicable to that the upper and lower water of solar water heater uses.
Existing water meter is all the one-way fashion water meter, when being used for showing the pondage of container at any time, as is used for solar water heater, then can't satisfy the use needs.
The purpose of this utility model is to provide a kind of special water meter that mainly is applicable to solar water heater, and this water meter can measure the upper and lower water yield easily, and can read at any time and remain the water yield.
The purpose of this utility model is achieved in that this water meter mainly is made up of watchcase, impeller, gear train, counting assembly etc., watchcase is provided with water inlet and the water delivering orifice that is positioned on the same axis, water can be flowed into or outflow by arbitrary end, be provided with impeller and two-way precision adjusting device between water inlet and the water delivering orifice, impeller is by gear train and counting assembly rigid attachment.Like this, no matter water from which end flows into, and the water yield all can be embodied on table.For cumulative errors appears in counting after preventing to use certain hour, cause the reading difficulty, the spy is provided with resetting means on counting assembly.
Below with reference to accompanying drawing structure of the present utility model and principle of work are described further.
Accompanying drawing is a structural representation of the present utility model.
By reference to the accompanying drawings, the utility model mainly comprises watchcase (1), impeller (7), two To precision adjusting device (2), transmission mechanism (4) and counting device (3). Watchcase (1 ) be provided with the entery and delivery port (as shown) that is positioned on the same axis, between intake-outlet If two-way precision adjusting device (2) and impeller (7), impeller (7) is by transmission device (4) Link with counting device (3), counting device (3) is provided with resetting means (5), by Be arranged on watchcase water and chew the adjustment screw at place (6), the water yield is aobvious in the time of can regulating two-way flow The precision of showing. Like this, current are when water meter, and the water yield just can be made things convenient for intuitively aobvious Show.
Operation principle of the present utility model: this water meter is installed on solar water heater Upper and lower water lines in, during upper water, the cold water water meter of flowing through impacts impeller (7) also Make its forward, by transmission mechanism (4) water yield being added up reaches counting device (3), Counting device (3) just can demonstrate the metering result---the water that stores in the water storage tank Amount. Similarly during water, hot water through water meter, impacts impeller (7) counter-rotating from reverse flow, Successively decrease thereby drive counting device (3), also can at any time show last water storage in the water storage tank Amount, after the certain hour use, water meter may cause out because there being accumulated error Existing residual value (when the water tank pondage is zero, is shown non-vanishing. ). At this moment, only need press meter Resetting means (5) in the counting apparatus (3) gets final product.
Compare with existing water meter, remarkable advantage of the present utility model is:
1, realizes bidirectional measuring.
2, the setting of two-way precision governor motion makes precision be improved.
3, the setting of resetting means can be removed cumulative errors easily.
Most preferred embodiment: mainly be applicable to the upper and lower water metering of household solar heat hydrophone.
(1), indication range: 0～999.9 liter
(2), display precision :≤1%
(30, physical dimension: high 80～100mm
Long 140～160mm
Bore φ 15mm
Claims (3)
1, a kind of digital two-way water meter that resets, by watchcase (1), impeller (7), gear train (4), counting assembly formations such as (3), it is characterized in that: watchcase (1) is gone up water inlet and water delivering orifice is positioned on the same axis, be provided with two-way precision adjusting device (2) in the watchcase (1), counting assembly (3) and gear train (4) rigid attachment.
2, by the described digital two-way water meter that resets of claim 1, it is characterized in that water inlet and water delivering orifice are positioned on the same axis.
3, by claim 1 and the described digital two-way water meter that resets of claim 2, it is characterized in that counting assembly (3) is provided with resetting means (5).
