Abstract
The invention relates to a momentum-type heat meter for heat metering of heating buildings, which consists of an integrator (1), a momentum-type flowmeter (2), a water supply thermometer (11), a return water thermometer (13) and a straight pipe (16). The momentum-type flowmeter (2) consists of a flowmeter shell (17), a force sensor (4), an elastomer (7), a force transmission bar (8), a fluid separator (9) and a momentum response piece (15). When the fluid in the straight pipe (16) flows and touches the momentum response piece (15), the momentum response piece (15) transfers the sensed fluid momentum to the fluid separator (9) via a momentum transmission bar (14) so as to cause the deformation of the elastomer (7) by a thrust and drive the force transmission bar (8) to move so that the force transmission bar (8) applies a force on the force sensor (4). The integrator (1) is used for acquiring the heating load of a heat user (12) by acquiring a stress signal of the force sensor (4), a temperature measuring signal of the water supply thermometer (11) and a temperature measuring signal of the return water thermometer (13) by means of a flow model and a heating output model of the built-in momentum-type flowmeter (1). The invention does not adopt rotatable parts, is resistant of fluid abrasion, and not affected by impurities of heating water and adherends and belongs to an anti-block wearable heat meter which is superior to a mechanical heat meter, an ultrasonic heat meter and an SST heat meter.
Description
One, affiliated technical field
What the present invention relates to is the technical field of heating household heat metering, is a kind of momentum-type heat meter.
Two, background technology
The hot First Astronautic Research Institute for Measurement and Test of heating household is a calorimeter with instrument, and it is made up of three big parts, is respectively flowmeter, water supply and return water temperature meter, integrator.The calorimeter of prior art is divided into three generations's calorimeter, and they are all using and also updating and developing, and be respectively: first generation calorimeter is the mechanical type calorimeter, and second generation calorimeter is a ultrasonic calorimeter, and third generation calorimeter is the SST calorimeter.This three generations's calorimeter is all identical aspect thermometric, and difference only is the measuring principle difference of its flowmeter.
The flow of mechanical type calorimeter is counted vane-wheel type flowmeter, and its measuring accuracy height, cost are low, but because it has rotatable parts is the flowmeter impeller, its serviceable life is shorter, and especially heating clean water quality degree is not high easily blocked; Ultrasonic flow meter is because of no-rotary part, and its life-span that seems is grown and measuring accuracy height, but there is a tangible technological deficiency in it, shows as its surface scale problem.Ultrasonic transmitter, ultrasonic receiver and be in measurement cavity between the two are easily adhered to by dirt in the water, the hydration of heating hot water especially, and its surface energy grows incrustation scale, and it is bigger that this convection current measures accuracy of measurement influence; The SST calorimeter adopts outstanding innovative technology: straight-through pipeline, symmetrical structure, transverse axis impeller and high abrasion nonmetallic bearing, become with anti-clogging, resistive connection dirt, long-life be the calorimeter of feature.
Although in the prior art, its combination property of SST calorimeter is better than mechanical type calorimeter and ultrasonic calorimeter, yet it also has impeller and these rotatable parts of bearing, the anti-clogging of its runner is still waiting to improve, the leeway that still has technology to improve is so also should remove to seek the heat meter flow that is more suitable for the metering of heating heat.
In order to overcome the technical deficiency of prior art heat meter flow, the present invention proposes a kind of momentum-type heat meter.
