Calorimeter sensor of momentum type

Abstract

The invention relates to a calorimeter sensor of a momentum type, used for metering the heat of a heating building. The calorimeter sensor of the momentum type comprises a straight tube (1), a temperature sensor (2), an outer shell upper plate (3), an elastic cavity (4), a force couple emitter (6), a cooling plate (7), a force sensor (8), a fluid baffle plate (9), an outer shell supporting body (10), a momentum transmission rod (11), a base bolt (12), a base (13) and a momentum sensor sheet (15), wherein the elastic cavity (4) is a tubular body, the upper end of the elastic cavity (4) is fixedly connected with the lower bottom surface of the outer shell upper plate (3), the inner wall surface of the lower end of the elastic cavity (4) is connected with the fluid baffle plate (9), a closed elastic cavity which is deformable in case of pressure is formed by the outer shell upper plate (3), the elastic cavity (4) and the fluid baffle plate (9), the force couple emitter (6) is fixed on the fluid baffle plate (9) in the elastic cavity, the upper end of a force couple receiving body (5) is fixedly connected with the outer shell upper plate (3), the lower part of the power couple receiving body (5) is arranged in the force couple emitter (6), and the force sensor (8) is fixed at one side of the lower end of the force couple receiving body (5) in the elastic cavity. The calorimeter sensor has no transmission part, resists fluid abrasion and blockage without being influenced by muddy heating water.

Description

1. Technical field [0001] The invention relates to the technical field of household heat metering for heating, and relates to a momentum type heat meter sensor. 2. Background technology [0002] The instrument used for heating household heat metering is a heat meter, which consists of three major components, namely a flow meter, a water supply and return water temperature difference meter, and a totalizer. The heat meters in the prior art are divided into three generations of heat meters, which are all in use and are still being improved and developed. They are respectively: the first generation of heat meters is a mechanical heat meter, the second generation of heat meters is an ultrasonic heat meter, and the third The substitute heat meter is the SST heat meter. These three generations of heat meters are the same in terms of temperature measurement, the only difference is that the measurement principle of their flowmeters is different. [0003] The flowmeter of the mecha...

Problems solved by technology

However, this kind of elastic tube, which plays a double role, uses the deformation of the elastic body to transmit the force and isolates the contact between the fluid and the force sensor, which are mutually restrained and contradictory, so it is difficult to ensure the effective force of the target induction force. transmission, and it is difficult to ensure the isolation effect between the fluid and the force sensor. It can be seen that the reliability and measurement accuracy of this target flowmeter are not high

[0006] In order to overcome the technical deficiencies of the heat meter flowmeter in the prior art, and the target flowmeter in the prior art cannot be directly used as a heat meter flowmeter, the present invention proposes a momentum heat meter sensor
