Description
Technical field
The utility model relates to water meter technical fields, and in particular to a kind of water meter in-line calibration structure.
Background technique
Water meter is one of main measurement instrument of urban water supply enterprise, is the important trade settlement tool of enterprise, and be to superintend and direct
Promote the important tool of people's water conservation, reasonable employment water resource, it is closely related with the vital interests of cities and towns huge numbers of families.For
It solves traditional water rate and shares dispute caused by charging mode equally, " one family of a table " is gradually carried out in China, from " one family of a table " policy
After implementation, the demand of water meter is even more to ramp.Foundation of the water meter as both sides of supply and demand meterage, accuracy is to consumption
Person and water undertaking all embody fair, just.The water meter calibration work in use is that water meter is torn open from use environment at present
It unloads down, is examined and determine in standard calibrating device.The method cannot effectively react the water meter real work situation.Currently, usually
Using statistical analysis technique or the addition means such as online detection instrument, it can be used to realize the supervision of water meter kinematic error and comment
Valence, but the accuracy of this in-line calibration method is difficult to ensure, and cannot function as metering whether accurate foundation.Existing market
The upper water meter temporarily without directly support in-line calibration.
Utility model content
Technical problem to be solved in the utility model is that one kind is provided for the above-mentioned prior art it is not necessary that water meter is certainly logical
It is disassembled in water lines, can realize the water meter in-line calibration structure of water meter indication error calibrating.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of water meter in-line calibration structure,
It is characterized in that: including
Water meter is connected on water pipe, and the water meter includes shell and setting in the intracorporal metering device of shell, the metering dress
It postpones and is provided with valve on the water pipe at end；
Intake is arranged between metering device and valve；
Sealing element, what can be dismantled is sealed on intake.
Selectively, it is in place that the rear end of metering device or intake setting on water meter is arranged in the intake
On water pipe between metering device and valve.
In order to facilitate connection water consumption measurement equipment, setting short tube is radially extended on the shell of the water meter or on water pipe
And form the intake.
Preferably, also covering is provided with tamper blocking on the sealing element, and the tamper blocking is bolted close
On sealing.
Facilitate installation ground, one week of intake upper end inner wall is formed with step, the sealing element matching limit setting
On step, gasket is provided between the sealing element and step.
Compared with the prior art, the advantages of the utility model are: the water meter in-line calibration structure passes through in water meter measurement
One intake is set between device and valve, the water for flowing through water meter is collected into calibrated collection vessel through the intake, is claimed
In the weight water consumption measurements equipment such as container, or the water consumption measurements equipment such as flow through proving flowmeter, compared in the same time with facilitating
Compared with the water value added of water meter and the water value added of water consumption measurement equipment, the error of indication of water meter is calculated, i.e., without disassembly
The calibrating that water meter is realized under the premise of water meter, solves the problems, such as that current water meter does not support in-line calibration, easy to operate, inspection
It is fixed at low cost.
Detailed description of the invention
Fig. 1 is the cross-sectional view of water meter in-line calibration structure in the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1, the water meter in-line calibration structure in the present embodiment, including water meter 1, intake 3, sealing element 4.
Wherein water meter 1 is connected on water pipe 2 compared with technology, and the water meter 1 in the present embodiment includes that shell 11 and setting exist
Metering device 12 in shell 11.It is provided with valve 21 on the water pipe 2 for being located at 12 rear end of metering device, which controls water
The on-off of water flow in pipe 2.In normal water supply use process, the valve 21 is in the open state, and water flow to water pipe 2 and flow to user
Water outlet water pipe 2 at, while be located at water pipe 2 on water meter 1 then the water flow in water pipe 2 is measured.Specifically, according to need
It wants, the rear end of metering device 12 on water meter 1 is arranged in intake 3, i.e., setting short tube is radially extended on the shell 11 of water meter 1,
The short tube then forms intake 3.Or intake 3 is arranged on the water pipe 2 between metering device 12 and valve 21, that is, is existed
Setting short tube is radially extended on water pipe 2 and forms intake 3.
3 upper end inner wall of intake is formed with step in one week, one sealing element 4 of matching setting, the sealing element on the step
4 can dismantle be sealed on intake 3, and be provided with gasket 41 between sealing element 4 and step, guarantee that sealing element 4 is taking
The leakproofness connected in the mouth of a river 3.Also covering is provided with tamper blocking 5 on sealing element 4 simultaneously, and tamper blocking 5 is connected by bolt
It connects on sealing element 4.
The use process of the water meter in-line calibration structure are as follows: when needing to examine and determine water meter 1, be first shut off valve
21, tamper blocking 5 is then removed, sealing element 4 is opened, dedicated water fetching device water intaking, dedicated water fetching device are connected on intake 3
It can be using water consumption measurements equipment such as calibrated collection vessel, calibrated weighing container, proving flowmeters.It will so flow through
The water of water meter 1 is collected into the water consumption measurements equipment such as calibrated collection vessel, weighing container through the intake 3, or is flowed through
Proving flowmeter, and then compare the water value added of water meter 1 and the water value added of water consumption measurement equipment in the same time, it counts
It calculates the error of indication of water meter 1 and solves current water that is, in the calibrating without realizing water meter 1 under the premise of dismantling water meter 1
Table 1 does not support the problem of in-line calibration, easy to operate, examines and determine at low cost.
