Description
Technical field
The present invention relates to a kind of physical measuring instrument, especially relate 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.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of novelty simple in structure, good seal performance, the ultrasonic calorimeter that measuring accuracy is high.
Technical scheme of the present invention 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.
Said tight locking button is that " [" type is equipped with rotation axis in these both sides, tight locking button bottom, on said gauge outfit seat, is provided with the rotation axis mounting groove, and said rotation axis is stuck in the said rotation axis mounting groove, and said tight locking button top is stuck in said gauge outfit and covers.Above structure makes that the gauge outfit lid is more reliable with being connected of gauge outfit seat, dismantles convenient.
In order to make the gauge outfit lid all consistent with the strength of each point of gauge outfit seat joint place, said tight locking button is two, and two these tight locking button symmetries snap onto the both sides of said gauge outfit seat and gauge outfit lid.
In order to make being connected of gauge outfit seat and Connection Block more reliable; Also be beneficial to simultaneously the rotation of calorimeter gauge outfit seat; Said gauge outfit seat bottom is provided with down protruding mounting hole; Said Connection Block is provided with the installation shaft of epirelief, and said installation shaft stretches in the said mounting hole, between said installation shaft outer wall and said mounting hole inwall, first O-ring seal is installed.
In said gauge outfit lid lower loop protruding mounting boss under being provided with; At said gauge outfit seat top ring to being provided with recessed installation annular groove; When said gauge outfit lid and gauge outfit seat are fitted; Said mounting boss embeds in the said installation annular groove, between said installing ring bottom land and said mounting boss lower end, second O-ring seal is housed.Adopt above structure, change existing radial seal and be the sealing of axial compression formula, good sealing effect, the permanent use can not make the O-ring seal distortion yet.
In said gauge outfit seat, be wholely set battery carrier, on this battery carrier, battery be installed.Adopt above structure, battery carrier and gauge outfit seat are one-body molded, have practiced thrift processing cost, and architecture is more reliable simultaneously.
Said battery carrier is made up of left and right elastic clip, and said left and right elastic clip is arcuate structure, and said battery is stuck in this left and right elastic clip.Adopt above structure, can make the fixing more reliable of battery.
Cover the end in said gauge outfit and have key hole, in said key hole, button is housed, have around the said key hole annular by keyway, said button embeds said pressing in the keyway.Adopt above structure,, prevent that effectively outer water or foreign material from getting into calorimeter, influences its measuring accuracy because the existence of pressing keyway makes the installation of button and gauge outfit lid have the effect of sealing.
For the installation that makes button has better sealing property, said button cross section is " M " word structure, and the center section of this button stretches in the said key hole, and Outboard Sections embeds said pressing in the keyway.
Beneficial effect: the present invention directly adopts the gauge outfit seat to be connected with Connection Block; Thereby make that meter reading is that gauge outfit can unitary rotation and dust cap is set; Sealing effectiveness is better, adopts tight locking button that gauge outfit lid and gauge outfit seat are fixed simultaneously, the assembling inconvenience when having avoided being threaded; Characteristics such as that the present invention has is simple in structure, safe and reliable, measuring accuracy height.
