Abstract

The invention discloses an integrated prepayment type ultrasonic heat meter which comprises an ultrasonic flow meter, a matched temperature sensor, a calculator, a card reader and a control valve. A meter core unit of the ultrasonic flow meter and a valve element unit of the control valve are arranged in the same shell, the front portion of the shell is provided with a water inlet, the water inlet is provided with outer tube threads of a connection pipeline, the meter core unit of the ultrasonic flow meter is arranged in an inner cavity of the middle portion of the shell, the valve element unit of the control valve is disposed in an inner cavity of the rear portion of the shell, the tail end of the shell is provided with a hole and is connected with the front portion of an end cap of the control valve through threads, the rear portion of the end cap of the control valve is provided with a water outlet, and the water outlet is provided with outer tube threads of the connection pipeline. By means of the design of the integrated structure, the meter core unit of the ultrasonic flow meter and the valve element unit of the control valve are arranged in the same shell, so that the heat meter is convenient to disassemble, assemble and maintain, the end cap of the control valve and the shell are sealed through a sealing ring, and metering precision and use reliability of the prepayment type ultrasonic heat meter are improved.

Description

technical field [0001] The invention relates to a heat meter, in particular to an integrated prepaid ultrasonic heat meter. Background technique [0002] At present, a heat meter is an instrument used to measure and display the heat energy released or absorbed by water flowing through a heat exchange system. It uses the physical quantities measured by two sensors - the flow rate of the heat carrier and the temperature of the inlet and outlet, and then through the compensation and integral calculation of the density and enthalpy value, the calorific value can be obtained. It is a mechatronics product based on microprocessors and high-precision sensors. Its working principle is: install the paired temperature sensors on the inlet and outlet pipes of the heat exchange circuit respectively, and install the flow sensor on the inlet or outlet On the pipe; the flow sensor sends out the flow signal, and the paired temperature sensor gives the temperature signal of the inlet and out...
