Description
Technical field
The utility model relates to a kind of physical measuring instrument, especially relates to a kind of ultrasonic calorimeter.
Background technology
As everyone knows, traditional flowmeter or heat energy table mechanical vane types or the rotary wind types etc. of adopting are directly proportional with flow according to the number of turns of wheel rotation more; Counter is through gathering the number of turns calculated flow rate of wheel rotation; Because there is mechanical wear in the rotation of impeller, so there are defectives such as weak point in serviceable life, structure vice president in traditional mechanical formula flowmeter or heat energy table, especially owing to reasons such as damage in impeller can cause the measuring accuracy reduction; In addition; Because fluid exists and to contain under the situation of impurity, mechanical flow meter or heat energy table usually can be therefore and having a strong impact on of being stopped up brings loss to the user.
At present, people use ultrasonic calorimeter to come calculated flow rate more, and ultrasonic calorimeter is to flow work to supersonic beam (or ultrasonic pulse) in order to measure the instrument of flow through test fluid.And the gauge outfit of the ultrasonic calorimeter that uses at present lid is installed on the gauge outfit seat; Adopt clamp ring that said gauge outfit lid is connected with the gauge outfit seat then; When this need see table; As long as the stem skull, but this kind mode uses the back to influence the calorimeter sealing easily often, thus cause the measuring accuracy of calorimeter to descend; Simultaneously; It is like this that the battery of the ultrasonic calorimeter that uses is at present installed: battery carrier independently is set in the gauge outfit seat, battery is fixed on the battery carrier get final product then, this kind structure needs the independent battery carrier of processing; Thereby increased processing cost, the battery carrier poor reliability has been installed simultaneously.
The utility model content
The utility model technical matters to be solved is to provide a kind of novelty simple in structure, good seal performance, the ultrasonic calorimeter that measuring accuracy is high.
The technical scheme of the utility model is following: a kind of ultrasonic calorimeter, comprise flowtube, and on this flowtube ultrasonic transducer is installed; Be fixed with Connection Block on the said flowtube, this connection flap is contained in said ultrasonic transducer top, is connected with the gauge outfit seat on the said Connection Block; This gauge outfit seat loam cake is equipped with the gauge outfit lid, covers end in this gauge outfit panel is installed, and its main points are: on said gauge outfit seat, be provided with tight locking button; This tight locking button bottom is installed on the said gauge outfit seat; Top snaps onto said gauge outfit and covers, and lid is equipped with dust cap above said panel, and this dust cap one side and said gauge outfit lid are hinged.Adopt above structure, have three benefits at least: the firstth, tight locking button directly is fixed together gauge outfit seat and gauge outfit lid, so convenient disassembly; The secondth, because the gauge outfit seat is fixedly connected with the gauge outfit lid, when therefore carrying out meter reading, be easy to rotate the gauge outfit of calorimeter, can not influence the sealing of the instrument in the gauge outfit, avoided the bad deficiencies of bringing such as measuring accuracy reduction of gauge outfit sealing effectiveness largely; The 3rd is the existence owing to dust cap, and dust and other impurities just can not polluted panel, only need dust cap be opened during reading and get final product meter reading.
On the sidewall of said gauge outfit seat, be provided with journal stirrup be installed down, be provided with on the sidewall of said gauge outfit lid with said install down journal stirrup corresponding on journal stirrup is installed, when said gauge outfit lid lid is contained on the said gauge outfit seat, said the applying of journal stirrup and last installation journal stirrup is installed down; On said tight locking button, be provided with keeper, this keeper snaps onto on said installation journal stirrup down and the last installation journal stirrup.Adopt above structure, on the existence of journal stirrup being installed and journal stirrup being installed down can simply and reliably gauge outfit lid and gauge outfit seat be locked.
