Description

A kind of heating heat measuring meter

The utility model relates to a kind of fluid heat measuring meter, and specifically a kind of heating heat measuring meter belongs to the heat metering field of instrumentation technology of central heating.Be fit to be installed on central heating user's confession, time jet chimney or the hot water pipeline, the heat of user heating consumption carried out the usefulness of meterage.

The heat metering instrument that has now occurred mainly contains two types of electronic type and mechanical types.The work essence of heat metering instrument, can think and exactly heat transfer medium steam or the hot water flow of supplying with the user be carried out cumulative measurement, while is according to the temperature difference of confession, backheat pipeline heat transfer medium, the measurement flow value that adds up is carried out suitable adjusting correction, thereby reflect the heat that the actual heating of user consumes.

Electronic type heat metering instrument is by the electronic type temperature-sensing element temperature signal of heat transfer medium to be converted to corresponding electric signal, and the electric signal with flow transmitter carries out the processing of electronics integrating then, thereby can draw the amount of heat that the actual heating of user consumes.Because the power supply power down problem of battery, high temperature causes shortcomings such as reliability is low, cost price height to the heat affecting problem of electronic component etc.

Mechanical type heat metering instrument mainly is an axial expansion after utilizing the temperature sensing medium that is sealed in the corrugated tube to be heated, the straight-line displacement that the temperature difference of confession, backheat pipeline heat transfer medium is converted to machinery changes, again by friction wheel mechanism or become tooth post mechanism the velocity of rotation of metering impeller is regulated variation, the cumulative measurement of finishing the actual consumption heat of figure case or the digit wheel mechanism by machinery at last.Because these mechanical type heat metering instrument structures are too complicated, caused shortcomings such as operation stability difference and cost price height.

The purpose of this utility model provides a kind of simple in structure, reliable and stable, mechanical type heat metering instrument that cost price is low.

The purpose of this utility model realizes in the following manner, the T-valve of band flowmeter is set on the heating inlet pipeline, the biconial valve plate is set in T-valve and on the valve rod of fixing valve plate, the spiral memorial alloy is set, in the lower end of T-valve hot sensing magnetic coupling is set, allows the heating backwater hot sensing magnetic coupling of flowing through.Just on the inlet channel and water return pipeline of heating, by T-valve and hot sensing magnetic coupling two mechanical type temperature-sensing elements (double metal spiral memorial alloy or marmem) are set, the anglec of rotation that the temperature variation of heat transfer medium on confession, the backwater hot channel is converted to machinery changes, be converted to the adjusting valve plate straight-line displacement variation up and down of T-valve again by the magnetic force coupled transmission mechanism, that is the variation of valve plate aperture.Thereby, the flow of two shunt conduit of flowing through is regulated variation.This has just determined the variation of metering wheel speed and the variable size of user heating consumption of calorie.

The utility model both can be used for the heat of user heating consumption is measured, also can to the central air conditioning user consume cold measure.The utility model can carry out elder generation's shunting metering to heat transfer medium, after shunt to regulate and implement.Also can carry out elder generation shunting and regulate heat transfer medium, after shunt metering and implement.

Accompanying drawing is a kind of structural representation of heating heat measuring meter.

Below with reference to Figure of description a kind of heating calorimeter of the present utility model being done in detail Bright.

A kind of heating calorimeter of the present utility model, its structure are by inlet triplet for water pipe 1, flowmeter 2, bypass pipe 3, triple valve, hot sensing magnetic coupling consist of the outlet pipe of flowmeter 2 and triple valve Upper water inlet 21 joins, and the lower water inlet 22 of the delivery port of bypass pipe 3 and triple valve joins, water inlet three The water inlet of two delivery ports of siphunculus 1 and flowmeter 2 and bypass pipe 3 joins, hot sensing magnetic coupling 8 Be arranged on the below of triple valve.

Triple valve is by valve body 15, biconial valve plate 4, valve rod 16, spring 5, differential nut 17, spiral shell Revolve memorial alloy 7 and consist of, the top of valve body 15 is provided with intake chamber 18, the middle part be valve plate chamber 19, The bottom is lower intake chamber 20, up and down intake chamber 18,20 respectively with upper water inlet 21 and lower water inlet 22 phases Logical, valve plate chamber 19 communicates with upper water-out mouth 6, and the up and down two ends of valve rod 16 are fixed on valve body about in the of 15 two On the axle bed of end, biconial valve plate 4, spring 5, differential nut 17 and spiral memorial alloy 7 are by extremely upper Under be fixed on the valve rod 16, biconial valve plate 4 is arranged in valve plate chamber 19, spring 5, differential nut 17 and Spiral memorial alloy 7 is positioned among the lower intake chamber 20.

Hot sensing magnetic coupling is to be made of housing 9, last disk 8, following disk 23, rotation axis 10 and spiral memorial alloy 11, last disk 8 is fixed on the lower end of valve rod 16, following disk 23 is fixed on the upper end of transmission shaft 23, the upper end of transmission shaft is passed the upper end of disk by bearing and housing and is joined, the lower end of transmission shaft 23 joins by the hypomere of bearing and housing 9, spiral memorial alloy 11 is arranged on the bottom of transmission shaft 23, and between backwater water inlet 12 that is arranged on housing 9 bottoms and backwater water delivering orifice 14.

Principle of work is:

When heat supply began, indoor temperature was lower,

The rotation of being heated of spiral memorial alloy drives the differential nut and rotates to an angle, and promotes the shunting valve plate and moves down, and the aperture of shunting valve plate increases, and the wheel speed of flowmeter is accelerated.

When water return pipeline heat transfer medium temperature increases, the rotation of being heated of spiral memorial alloy in the hot sensing magnetic coupling, drive equidirectional the rotating to an angle of valve plate of T-valve by the magnetic force coupling of disk up and down, differential by the differential nut, the shunting valve plate is moved up, the aperture of shunting valve plate reduces, and the wheel speed of flowmeter reduces.Thereby can realize, according to the difference variation for, backheat pipeline heat transfer medium, regulate two shunt conduit bypass flows, enforcement the utility model carries out simple and reliable metering to the heat of user heating consumption.
