Description
Technical field
The utility model belongs to acoustics, field of sensing technologies, particularly utilizes the converter of fluid flow in ultrasonic detecting technology metering conduit, is applicable to the metering of fluid flow in pipeline, heat.
Background technology
At present, Ultrasonic water meter, the calorimeter of prior art form primarily of converter, measurement pipeline section and controller, and require that meter case sealing protection effect reaches IP68 grade (with reference to standard GB/T 4208-93).Mainly contain the parts compositions such as movement circuit plate, battery, terminal box in converter shell, circuit part is formed by connecting by welding or plug by each parts, generally reached the sealing effectiveness of the IP68 grade of national regulation by the embedding of complete machine casting glue.In use there is following problem in this encapsulating method:
1, casting glue consumption is large, and cost is high, and casting glue water content is high, easily on water meter cover, forms aqueous vapor, affects meter reading
2, converter could use casting glue embedding after wanting final assembly, and the instrument production cycle is long, and throughput rate is low
3, casting glue makes sealing effectiveness decline along with the change of environment temperature is expanded with heat and contract with cold in long-time use procedure, destroys the sealing of instrument;
4, when instrument is safeguarded, first to remove casting glue, could keep in repair or change instrument device, and then use casting glue embedding, until casting glue hardens completely, be inconvenient to operate.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Ultrasonic water meter, Calorimeter Using For Converter, and this converter significantly enhances sealing property and the assembling convenience of instrument, and reduce cost, production efficiency have also been obtained great raising.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of Ultrasonic water meter, Calorimeter Using For Converter, comprise the circuit unit being positioned at and measuring cavity above pipeline section, be located at cavity, be located at the transparent panel of cavity oral area and cover the fixed frame with window on transparent panel, it is characterized in that: described cavity oral area has step seam, between described transparent panel edge and step seam, there is the gasket seal that cross section is L-type; Described cavity is vacuum chamber.
In embodiment of the present utility model, in described circuit unit, include negative pressure monitor.The vacuum tightness in converter cavity can be recognized so in real time.
In embodiment of the present utility model, in described circuit unit, also include two infrared probes.Like this, this two infrared probes and extraneous Direct Communication can be utilized, make not need inside and outside converter to be communicated with by the mode of connection.
Described cavity is circular cavity.Described transparent panel is tempered glass.Described fixed frame is connected with table cover.
Adopt technique scheme, the utility model adopts L-type gasket seal to seal between cavity and transparent panel, facilitates the realization of evacuation process, and adopts such sealing means, steam can not be produced in cavity, also greatly improve production efficiency simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Fig. 1 is perspective view of the present utility model;
In figure:
100-measures pipeline section, 200-cavity, 201-step seam, 300-transparent panel, 400-fixed frame, 401-window, 500-gasket seal, 600-table cover.
Embodiment
As shown in Figure 1, Ultrasonic water meter of the present utility model, Calorimeter Using For Converter, comprise the circuit unit (not shown) being positioned at and measuring cavity 200 above pipeline section 100, be located at cavity 200, be located at the transparent panel 300 of cavity oral area and cover the fixed frame 400 with window 401 on transparent panel 300.
Wherein, circuit board, display board, chip, negative pressure monitor and two infrared probes etc. are included in circuit unit.
Cavity 200 is cavity, has step seam 201 at cavity 200 oral area, has the gasket seal 500 that cross section is L-type between transparent panel 300 edge and step seam 201.Sealed by transparent panel 300 and gasket seal 500, by evacuation process, make annular seal space 200 be vacuum chamber.
For bearing enough large pressure, transparent panel 300 adopts tempered glass.In addition, fixed frame 400 also connects and table cover.
The utility model adopts L-type gasket seal to seal between cavity and transparent panel, facilitates the realization of evacuation process, and such sealing means, can not produce steam in cavity, the production and assembly of instrument are convenient, production efficiency is high.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; have in any art and usually know the knowledgeable; if in the protection domain not departing from the claim that the utility model proposes; the Equivalent embodiments that local done by the technology contents utilizing the utility model to disclose is changed or modified, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
