Abstract
The utility model relates to a pressure type capillary of a thermograph, which is characterized in that a capillary is arranged between the thermograph head and a temperature bag which is used for testing the temperature. The capillary is a red copper pipe and has an external radius between 2 to 3. When the brass wire weaved layer coating the capillary, the internal radius of the capillary is still 0.2 to 0.5. The thermograph with the utility model saves cost and and prolongs service life of the thermograph.
Description
The utility model relates to the automation instrument technology field, belongs to the kapillary of temperature survey lead-in wire in the pressure-type thermometer specifically.
The present employed kapillary of pressure-type thermometer, generally be to make kapillary by Φ 1.2～Φ 1.6 copper pipes, at copper kapillary outside coppered wire braid, the thickness of its braid is 0.6～0.7, braid is that copper wire is 0.18, when this is shown in use, because the corrosion of environment comprises braid and tubule, the influence of simultaneously artificial roll compacting, kinking etc., leakage causes instrument to lose efficacy to cause whole kapillary that fracture takes place, can not normally use, this type of situation often takes place, and people often feel extremely inconvenience for this reason.
It is higher relatively that the purpose of this utility model provides intensity capillaceous, and its endoporus capillaceous is constant, and be not subject to environment and artificial influence and a kind of pressure-type thermometer kapillary capillaceous that fractures.
For finishing the technical scheme that above-mentioned purpose is taked: with existing pressure-type thermometer kapillary lead-in wire is gauge outfit and the measurement temperature kapillary between the thermometer bulb, and its copper tube external diameter capillaceous is Φ 2～Φ 3, and endoporus capillaceous is Φ 0.2～0.5.
The utility model is removed the outer copper wire braid that is provided with of original pressure-type thermometer kapillary, strengthen the copper tube diameter, increase whole intensity capillaceous, corresponding technology is simply saved cost, be difficult for being split off life-saving by environment and artificial factor.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural drawing.
According to shown in Figure 1, be provided with the lead-in wire that kapillary is a thermometric between the thermometer bulb 3 of the gauge outfit 1 of instrument and measurement temperature, kapillary 2 is made up of copper tube, its external diameter is Φ 2～Φ 3, the endoporus of kapillary 2 is between Φ 0.2～Φ 0.5, and is identical with the internal diameter of the kapillary endoporus of prior art, removes the copper wire braid in the prior art kapillary outside, it is thick to thicken an ancient piece of jade, round, flat and with a hole in its centre capillaceous, increases bending strength capillaceous.
Claims (1)
1, a kind of pressure-type thermometer kapillary of forming by gauge outfit, kapillary, flexible member and thermometer bulb, it is characterized in that gauge outfit (1) and measure between the thermometer bulb (3) of temperature and establish kapillary (2), the copper tube external diameter of its kapillary (2) is Φ 2～Φ 3, and the endoporus of kapillary (2) is between Φ 0.2～Φ 0.5.
