Abstract
The invention discloses an ultrasonic calorimeter, comprising a flow tube. The flow tube is provided with an ultrasonic transducer and is fixed with a connecting seat. The connecting seat is arranged above the ultrasonic transducer in a covering manner. The connecting seat is movably connected with a gauge head seat. The gauge head seat is covered by a gauge head cover. An upper end of the gauge head cover is provided with a panel. The gauge head seat is provided with a lock buckle. A lower part of the lock buckle is arranged on the gauge head seat, and an upper part of the lock buckle is bucked on the gauge head cover. A dustproof cover covers the panel, and one side of the dustproof cover is hinged to the gauge head cover. With the adoption of the abovementioned structure, the lock buckle directly fixes the gauge head seat and the gauge head cover, and the disassembly is convenient. During calorimeter reading, the head of the calorimeter is easy to rotate while sealing of instruments in the head cannot be influenced, so that defects that measurement precision is reduced and the like due to poor sealing of the head are prevented to a large extent. Due to the dustproof cover, foreign materials such as dust are prevented from contaminating the floor.
Description
Technical field
The present invention relates to a kind of physical measuring instrument, especially relate to a kind of ultrasonic heat meter.
Background technology
As everyone knows, conventional flow meters or heat energy meter many employings mechanical impellor formula or rotary wind type etc., the number of turns according to wheel rotation is directly proportional to flow, counter is by gathering the number of turns calculated flow rate of wheel rotation, because the rotation of impeller exists mechanical wear, therefore to there is serviceable life short for traditional mechanical flowmeter or heat energy meter, the defects such as structure vice president, especially because the reasons such as damage in impeller can cause measuring accuracy to reduce, in addition, due to fluid exist containing impurity when, what therefore mechanical flowmeter or heat energy meter usually can be blocked has a strong impact on, loss is brought to user.
At present, people's many uses ultrasonic heat meter carrys out calculated flow rate, and ultrasonic heat meter is to the instrument of the work of supersonic beam (or ultrasonic pulse) in order to measuring flow by test fluid flowing.And the gauge outfit lid of the ultrasonic heat meter used at present is arranged on gauge head seat, then clamp ring is adopted to be connected with gauge head seat by described gauge outfit lid, when this needs to see table, as long as stem skull, easily affect calorimeter sealing after but this kind of mode normal time uses, thus cause the measuring accuracy of calorimeter to decline; Simultaneously, it is like this that the battery of the ultrasonic heat meter of current use is installed: in gauge head seat, independently arrange battery carrier, be then fixed on battery carrier by battery, this kind of structure needs to process battery carrier separately, thus add processing cost, battery carrier poor reliability is installed simultaneously.
Summary of the invention
It is simply novel that technical matters to be solved by this invention is to provide a kind of structure, the ultrasonic heat meter that good seal performance, measuring accuracy are high.
Technical scheme of the present invention is as follows: a kind of ultrasonic heat meter, comprise flowtube, this flowtube installs ultrasonic transducer, described flowtube is fixed with Connection Block, this Connection Block mounts cover above described ultrasonic transducer, described Connection Block is connected with gauge head seat, this gauge head seat upper cover is equipped with gauge outfit lid, cover end in this gauge outfit and panel is installed, its main points are: on described gauge head seat, be provided with tight locking button, this tight locking button bottom is arranged on described gauge head seat, upper buckle is connected on described gauge outfit and covers, side has mounted cover dust cap on the panel, this dust cap side and described gauge outfit lid hinged.Adopt above structure, have three benefits at least: first is that gauge head seat and gauge outfit lid are directly fixed together by tight locking button, convenient disassembly like this; Second is because gauge head seat is fixedly connected with gauge outfit lid, when therefore carrying out meter reading, is easy to the gauge outfit of rotating calorimeter, can not affects the sealing of the instrument in gauge outfit, avoid the deficiencies such as the bad measuring accuracy reduction brought of gauge outfit sealing effectiveness largely; 3rd is the existence due to dust cap, and dust and other impurities would not pollute panel, only needs dust cap to open to get final product meter reading during reading.
The sidewall of described gauge head seat is provided with lower installation journal stirrup, the sidewall of described gauge outfit lid is provided with the upper installation journal stirrup corresponding with described lower installation journal stirrup, when described gauge outfit lid mounts cover on described gauge head seat, described lower installation journal stirrup and the laminating of upper installation journal stirrup; Described tight locking button is provided with keeper, and this keeper snaps onto on described lower installation journal stirrup and upper installation journal stirrup.Adopt above structure, the existence of upper installation journal stirrup and lower installation journal stirrup can simply and reliably by gauge outfit lid and gauge head seat locking.

In order to make the strength of each point of gauge outfit lid and gauge head seat joint place all consistent, described tight locking button is two, and two this tight locking button symmetries snap onto the both sides of described gauge head seat and gauge outfit lid.
In order to make the connection of gauge head seat and Connection Block more reliable, also be beneficial to the rotation of calorimeter headstock simultaneously, described gauge head seat bottom is provided with lower convex mounting hole, described Connection Block is provided with the installation shaft of epirelief, described installation shaft stretches in described mounting hole, between described installation shaft outer wall and described mounting hole inwall, be provided with the first O-ring seal.
Protruding to being provided with lower convex installation at described gauge outfit lid lower loop, at described gauge head seat top ring to being provided with recessed installation annular groove, when described gauge outfit lid and gauge head seat laminating, described installation projection embeds in described installation annular groove, between described installing ring bottom land and the protruding lower end of described installation, the second O-ring seal is housed.Adopt above structure, changing existing radial seal is the sealing of axial compression formula, and good sealing effect, permanent use also can not make sealed ring deformation.
In described gauge head seat, be wholely set battery carrier, this battery carrier has been provided with battery.Adopt above structure, battery carrier and gauge head seat one-body molded, saved processing cost, simultaneously structure structure is more reliable.
Described battery carrier is made up of left and right elastic clip, and described left and right elastic clip is arcuate structure, and described Battery Card is in this left and right elastic clip.Adopt above structure, the fixing more reliable of battery can be made.
Cover end in described gauge outfit and have key hole, at described key hole built with button, have around described key hole annular by keyway, press in keyway described in described button embeds.Adopt above structure, owing to pressing the existence of keyway, make the Packed effect of the tool for mounting of button and gauge outfit lid, effectively prevent extraneous water or foreign material from entering calorimeter, affect its measuring accuracy.
In order to make the installation of button have better sealing property, described button cross section is in " M " word structure, and the center section of this button stretches in described key hole, presses in keyway described in Outboard Sections embeds.
Beneficial effect: the present invention directly adopts gauge head seat to be connected with Connection Block, thus make meter reading be that gauge outfit can unitary rotation and arrange dust cap, sealing effectiveness is better, adopts tight locking button gauge outfit lid and gauge head seat to be fixed simultaneously, avoids assembling inconvenience when being threaded; The present invention has that structure is simple, safe and reliable, measuring accuracy high.
