Abstract
The invention discloses a bimetallic thermometer calibration device, which comprises an incubator, wherein a console is arranged on the incubator; a water tank is arranged inside the incubator, and a heating rod is arranged inside the water tank; a cover plate is arranged on the incubator, and the cover plate is provided with a plurality of positioning tubes; and a positioning hole is formed in the incubator, and a limiting clamp and a heating switch are arranged on the console. The bimetallic thermometer calibration device is used for calibrating bimetallic thermometers in use at regular or irregular intervals, can ensure the accuracy of the bimetallic thermometers, and satisfies the requirements for production environment and equipment temperature control of enterprises.
Description
Technical field
The present invention relates to weaving dedicated test utensil, be specifically related to a kind of bi-metal temperature meter checking device.
Background technology
At cotton spinning, dyeing, the bimetallic system cell of middle low form be cooling plant for controlling the one important measuring instrument of refrigeration plant to workshop input humiture, such instrument is widely used for weaving, in dyeing to desizing machine, mixing cirtern, mercerizing range, boil the control of the equipment such as drift machine, soaper.When such instrument uses on equipment, owing to running in the environment of various temperature, slurry all the time, its temperature sensing device and panel board are all vulnerable to corrosion, cause the precise decreasing of instrument, enterprise are lost efficacy to the monitoring of production equipment temperature, has influence on product quality.This type of instrument is large in enterprise's amount, and distribution is wide, and only send professional institution to detect if every, one is impact production on schedule, two be censorship costly, enterprise is difficult to bear.
Summary of the invention
Technical matters to be solved by this invention is to provide the meter checking device of metal temperature in pairs that a kind of structure is simple, easy to operate, checking precision is high.
For solving the problems of the technologies described above, a kind of bi-metal temperature meter checking device of the present invention, comprises constant temperature oven, described constant temperature oven is provided with control desk; Described constant temperature oven is built-in with tank, and described tank is built-in with heating rod; Be provided with cover plate above described constant temperature oven, described cover plate is provided with some positioning pipes; Described constant temperature oven is also provided with pilot hole, described control desk is provided with limiting card and heater switch.The present invention detects numeric ratio to determining bimetallic system cell measured value precision whether in tolerance by standard thermometer and bimetallic system cell to be verified with region water temperature, continues to use, exceed franchise and then replace as qualified.During operation, bimetallic system cell to be measured is inserted positioning pipe respectively, in pilot hole, inserts standard thermometer; During detection, tank inserted by standard thermometer and bimetallic system cell, and tank water filling is afterwards heated, and standard thermometer indicating value and bimetallic system cell indicating value are distinguished comparison, to determine that whether bimetallic system cell temperature measurement accuracy is qualified by different water temperature numerical value by operating personnel.
Further, described cover plate is provided with and carries button.It facilitates cover plate to promote, and operates more convenient, efficient.
The present invention regularly or irregularly verifies the bimetallic system cell in use, ensures the accuracy of bimetallic system cell, meets the requirement that enterprise controls production environment and device temperature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is working state structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described;
Visible as shown in Figure 1, Figure 2, a kind of bi-metal temperature meter checking device of the present invention, comprises constant temperature oven 100, described constant temperature oven 100 is provided with control desk 101; Described constant temperature oven 100 is built-in with tank 106, and described tank 106 is built-in with heating rod 102; Be provided with cover plate 200 above described constant temperature oven 100, described cover plate 200 is provided with some positioning pipes 202; Described constant temperature oven 100 is also provided with pilot hole 105, described control desk 101 is provided with limiting card 104 and heater switch 103.
Described cover plate 200 is provided with carries button 201.
The good leakproofness of constant temperature oven 100 tool of the present invention, can guarantee temperature measuring area temperature consistency, stability, provides advantage to lower step accurate verification; Limiting card 104 pairs of thermometric process Plays thermometers 400 are fixed, easy to loading and unloading.Before operation, first in tank 106 retaining, then insert bimetallic system cell 300 respectively by between positioning pipe 202, tank 106 can be inserted with bimetallic system cell 300 and be as the criterion, cover plate 200 is positioned on constant temperature oven 100 form a confined space within it afterwards; Moreover standard thermometer 400 fixed by limiting card 104 and inserts tank 106.Under the environment of room temperature, be heated to each temperature spot by heating rod 102 pairs of tank 106 inner cold waters, as 30 DEG C, 40 DEG C, 50 DEG C etc.Under each temperature spot state, the indicating value of bimetallic system cell 300 indicating value and standard thermometer 400 is compared, writes down difference.If without difference, then show that by the bimetallic system cell 300 in school be accurately.If there is difference, is then qualified within the franchise specified in enterprise, exceeds tolerance and then judge that by school bimetallic system cell 300 be underproof.
Because the present invention detects comparison after the match in same temperature, the scale division value of accepted standard thermometer 400 is 0.1 DEG C, it is 1 DEG C by the scale division value of school bimetallic system cell 300, the precision of its standard thermometer 400 reaches by 10 of school bimetallic system cell 300 times, by measurement and calibration principle, calibration criterion should higher than by school accuracy of instrument 3-5 times, therefore the present invention can meet the verification requirement of bimetallic system cell 300.
The present invention can simultaneously to multiple metallic thermometer 300 measured value, and it detects efficiently, measured value is accurate.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.
