Description
Technical field
The utility model relates to a kind of for measuring the flow rate of water flow in the heating system, the ultrasonic calorimeter of flow, is specifically related to the constant-current stabilizer of this ultrasonic calorimeter.
Background technology
Ultrasonic calorimeter is calorimeter more advanced in the prior art, specifically utilize ultrasound wave to measure and enter flow velocity, the flow of showing the current between the inherent water inlet of body and the water delivering orifice in the heating system, and then user's the heating water yield is measured and charging.Existing supersonic wave calorimeter current-stabilizing device, as shown in Figure 1, the approximate straight tube shape of water inlet portion I cavity shape on the table body, the unstable current of fluctuation flow into from the water inlet portion I to be shown in the body, flow velocity is not yet stable, even also there are whirlpool in current, the measured zone that has little time that flow velocity is tended to be steady and just enter the ultrasonic transducer 14 in the calorimeter, cause the ultrasonic measurement flow velocity not accurate enough, and then affected the calorimeter measurement accuracy.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, steady flow result better so that ultrasonic measurement result supersonic wave calorimeter current-stabilizing device more accurately.
The utility model supersonic wave calorimeter current-stabilizing device, comprise water entering section, the pars intermedia that is positioned at left end and the outlet part that is positioned at right-hand member, the cavity shape of described pars intermedia is straight barrel type, link position place with water entering section and outlet part on the pars intermedia all is equipped with ultrasonic transducer, has ganoid annular projection on the described water entering section inner chamber, the water entering section cavity shape that is arranged so that of described annular projection is the hourglass shape that the longitudinal section area dwindles gradually and slowly increases first, and the junction of described water entering section inner chamber and pars intermedia inner chamber seamlessly transits.
In the utility model, can be following two kinds of array modes between annular projection and the water entering section body: (1) described annular projection and described water entering section are split-type structural, and described annular projection is installed in the described water entering section; (2) described annular projection and described water entering section are one-body molded.
The utility model supersonic wave calorimeter current-stabilizing device, the minimum diameter d of wherein said water entering section inner chamber is 15mm, and the maximum diameter d of water entering section inner chamber is 22mm, and the intracavity diameter of pars intermedia is 22mm.This is a kind of embodiment in the utility model the is applied in little table body, adopt the water entering section current-stabilizing structure of this size after, steady flow result is better.
The utility model supersonic wave calorimeter current-stabilizing device, wherein said water entering section, pars intermedia and outlet part are one-body molded.
The utility model supersonic wave calorimeter current-stabilizing device, wherein said water entering section, pars intermedia and outlet part are made by stainless steel material.
The utility model difference from prior art is: the utility model supersonic wave calorimeter current-stabilizing device, water entering section inner chamber at existing calorimeter increases the smooth annular projection of a circle, the water entering section cavity shape that is arranged so that of this annular projection is the hourglass shape that the longitudinal section area dwindles gradually and slowly increases first, that is: at the water entering section inner chamber elder generation is set and shrinks again the slowly throat structure of expansion along smooth curve, wherein the contraction section in left side plays 3 effects: reduce gradually the current cross-sectional area 1., accelerate the decay of incoming flow whirlpool, improve the energy exchange of current inside, the incoming flow current are played rectified action; 2. when current were along contraction flow, the hole wall segregation phenomenon can not occur, avoided new vortex arising; 3. smooth contraction can reduce the pressure loss that reduces to produce because of the caliber cross-sectional area.The expansion segment on right side adopts excessively mild, and the one, avoid producing and separate whirlpool, play rectified action, the 2nd, reduce water velocity, reduce current in the energy loss at mirror structure place, reduce crushing.The annular projection structure that the utility model adopts at water entering section, can play rectified action to incoming flow well, simultaneously avoid again the generation of new whirlpool and the pressure loss excessively to increase, greatly improved the adaptability of heat meter to different incoming flows, improved the calorimeter measurement accuracy.
Below in conjunction with accompanying drawing supersonic wave calorimeter current-stabilizing device of the present utility model is described further.
