Abstract

The utility model discloses a water temperature gauge. A temperature is preset as the critical value before the water temperature gauge is used; an impeller 2 is driven to move when the cold water in a water pipe flows through the water temperature gauge, the water flow is transmitted to a calculation module 4 through a flow sensor 3, and is displayed at a display port 5 according to the gauging of the cold water standard and then is output to an automatic accounting system, etc. through an data output port 6; when a temperature sensor 7 detects that the water temperature in a water pipe 1 is above the critical temperature, the calculation module 4 gauges and displays the data according to the hot water standard, and at the same time, the relevant data are output through the data output port 6. The water temperature gauge is more scientific and reasonable because the user does not pay for the cold water which is lower than the using standard with the expensive charge of hot water.

Description

A kind of temperature-sensitive water meter

Technical field

The present invention relates to a kind of surveying instrument, especially a kind of instrument of measuring fluid flow.

Background technology

Along with improving constantly of China people people life level, living conditions improve day by day, increasing family uses and gone up the hot water and the heating installation of unified supply, have exempted that every family oneself is in the past heated up water and the trouble of heating.Certainly, these all are to need charge, especially heating installation, and the classic method of chargeing according to the area of residence from the past carries out the transition to more scientific and reasonable each door type metering just gradually.At therewith, prior art generally is at the end of registering one's residence of hot water and caliduct a water meter to be installed, and measures the hot water flow that flows through, and is charged according to the hot water amount who uses by the person of checking meter subsequently, is perhaps deducted from prepaid expense by automatic accounting system.But, hot water can not use in 24 hours, leave unused and to cool off gradually at ducted hot water, all need the user to bleed off the water that some have cooled off before the at interval long each time use in advance, especially most of resident family does not use under the situation of hot water in a building residential building, and first user need bleed off a large amount of cold water and the hot water in the trunk line could be introduced.Also there is analogue in caliduct, before each heating season begins, and the reliability that a large amount of cold water that all needs to circulate comes test pipe, and then it is required gradually water temperature to be brought up to heating.And these bleed off or round-robin cold water, but need the user to come defrayment according to the higher hot water of price, and this obviously is irrational.

Summary of the invention

Can not distinguish the deficiency that hot and cold water measures in order to overcome prior art, the utility model provides a kind of temperature-sensitive water meter.

The technical scheme that its technical matters that solves the utility model adopts is: comprise the impeller 2, flow sensor 3, computing module 4, display port 5 and the data-out port 6 that place water pipe 1.Impeller 2 connection traffic sensors 3, flow sensor 3 connects computing module 4, and computing module 4 is connected with display port 5 and data-out port 6.It is characterized in that: also have a temperature sensor 7 to be positioned in the water pipe 1, be connected with computing module 4.Preestablish what a temperature before the use as critical value, impeller 2 when the cold water in the water pipe flow through, by flow sensor 3 discharge is transferred to computing module 4, is presented at display port 5 according to the standard metering of cold water, and can exports to automatic accounting system etc. by data-out port 6; When temperature sensor 7 detected water temperature in the water pipe 1 and surpasses critical temperature, computing module 4 was according to the standard metering of hot water and show, simultaneously by data-out port 6 output related datas.

The utility model can also adopt sectional type computing module 4, can set several different temperature values in computing module 4, when temperature sensor 7 detected water temperatures are in different phase, measures according to predefined standard.

The beneficial effects of the utility model are: owing to adopt the temperature-sensitive water meter, the user is no longer necessary for the more high hot water expense of cold water payment that is lower than the use standard, and is more scientific and reasonable.Simultaneously, the utility model also has good result for the situation not up to standard of heating temperature in heating season.

The present invention is further described below in conjunction with drawings and Examples.
