A kind of ultrasound wave heat household metering table

Technical field

The utility model relates to the household based heat metering technical field, specifically a kind of ultrasound wave heat household metering table.

Background technology

At present, for the form of tariff of urban and rural housing heating, mostly be to get expense by the heating area in house, there is groundless, the unscientific drawback of collecting the charges of use heat in it.To this, people have researched and developed ultrasound wave heat household metering table, and it can accurately measure each user's heating use amount, have therefore guaranteed the rationality of actual heating and science charge, have received the widely acceptance in market.

Existing ultrasound wave heat household metering table is in the middle of reality is used; It is found that coarse situation appears measuring in calorimeter sometimes when work; Problem through experiment discovery repeatedly is: one, the distance of the installation site of calorimeter and supplying heat source inlet is far away more; Its error in dipping is big more, and each residing position of heating user has nothing in common with each other in reality, and error has more or less appearred in the heating metering that has occurred equal area user thus; Will be when two, heating in the winter time according to the difference of physical environment temperature because of heating power unit; Often to adjust the pressure and the flow velocity of heating hot water; With energy savings, when pressure and the flow velocity of heating hot water changed, error more or less can appear in identical heating area user's calorimeter equally.

To this; Find that through repeatedly searching reason the structure in the parts is unreasonable; That is: measure cross aquaporin in the pipe fitting the center position place vertically to first reverberator and second reverberator have been installed, when heating hot water through in the parts time, current can be respectively to first reverberator with second reverberator produces bump and the phenomenon of shunting occurs in its both sides; This phenomenon produces certain turbulent flow and bubble easily in measuring pipe fitting; It directly has influence on the operate as normal of measurement of correlation parts on the WT-MSR, thus, and the error in dipping that causes WT-MSR when work, to occur easily.

The utility model content

The purpose of the utility model provides a kind of ultrasound wave heat household metering table; It can solve that prior art exists because heating hot water is easy to generate turbulent flow and bubble during through the measurement pipe fitting in the table body, and causes WT-MSR in the table body problem of error in dipping to occur.

The purpose of the utility model realizes through following technical scheme: a kind of ultrasound wave heat household metering table; It comprises the table body, and the table body is made up of WT-MSR and measurement pipe fitting, and WT-MSR is connected with second sensor with first sensor respectively through lead; Measure on the pipe fitting and offer water inlet, water delivering orifice, first measuring port, second measuring port and the sensor socket that communicates with each other respectively; Water inlet and water delivering orifice are separately positioned on the right ends of measuring pipe fitting, and first measuring port and second measuring port are separately positioned on the top of measuring pipe fitting, and it has distance each other; Sensor socket is arranged on to be measured on the pipe fitting, and corresponding with water delivering orifice; Measure in the pipe fitting first reverberator and second reverberator are installed respectively; First reverberator is corresponding with first measuring port and second measuring port respectively with second reverberator; Offer first through hole on first reverberator; Offer second through hole on second reverberator, first through hole is corresponding with water inlet and water delivering orifice respectively with second through hole.

Be further to realize the purpose of the utility model, also can accomplish through following technical scheme: first reverberator and second reverberator are respectively that to be vertical in form cylindric, and the top of first reverberator is skewed; First reflecting surface is arranged on its dip plane; The top of second reverberator is skewed, and second reflecting surface is arranged on its dip plane, and first reflecting surface is corresponding each other with second reflecting surface; First through hole is arranged on the bottom of first reflecting surface, and second through hole is arranged on the bottom of second reflecting surface.Measure the internal diameter of the internal diameter of middle position in the pipe fitting less than the measurement pipe fitting, and on the inwall of middle position, offer screw thread, the length of its screw thread is corresponding with the distance between first measuring port and second measuring port.

The beneficial effect that the utility model can produce: because of on first reverberator and second reverberator, offering first through hole and second through hole respectively; First through hole is corresponding with water inlet and water delivering orifice respectively with second through hole; So; The shunting that hot water forms on first reverberator and second reverberator when measuring in the pipe fitting of can effectively avoiding heating of first through hole and second through hole; It has fundamentally eliminated turbulent flow and bubble phenomenon that current occur in measuring pipe fitting, so fundamentally solved error in dipping appears in existing ultrasound wave heat household metering table easily when work problem.

To be vertical in form cylindric because of first reverberator and second reverberator are respectively, and the top of first reverberator is skewed, and first reflecting surface is arranged on its dip plane; The top of second reverberator is skewed; Second reflecting surface is arranged on its dip plane, and first reflecting surface is corresponding each other with second reflecting surface, and first through hole is arranged on the bottom of first reflecting surface; Second through hole is arranged on the bottom of second reflecting surface; So it not only can make the structure of reverberator simple more, manufacturing cost is cheaper, and feasible the installation and the maintenance job simple and fast.

Because of the internal diameter of measuring middle position in the pipe fitting less than measuring the pipe fitting internal diameter; And on the inwall of middle position, offer screw thread; The length of its screw thread is corresponding with the distance between first measuring port and second measuring port; So it can further suppress turbulent flow that current produce and bubble phenomenon through to measuring the mode that middle position in the pipe fitting dwindles internal diameter and offers screw thread within it on the wall.

The utility model can fundamentally solve the error in dippings that existing ultrasound wave heat household metering table is different because of the installation site, heating pressure difference occurs easily, and widespread use can produce tangible society, economic benefit.
