Description

High-pressure fluid temperature measuring equipment in managing
Technical field
It is especially a kind of for managing the temperature measuring equipment of interior high-pressure fluid the present invention relates to a kind of fluid temperature measuring equipment.
Background technique
CO2 is in a supercritical state in the gas cooler of heat pump cycle, and pressure is high, physical property changes greatly, heat transfer mechanism Complexity studies supercritical CO 2 flow behavior and heat transfer characteristic, can provide fundamental basis for the design of supercritical CO 2 heat exchanger, right The performance for improving CO2 heat pump water heater system has important academic significance and practical value.Since CO2 is in supercritical state State, the pressure in pipe is higher, and the measurement of tube fluid temperature is extremely difficult.When tube fluid pressure is higher, direct aperture is inserted Enter temp measuring method in the pipe of formula, the leakage of high-pressure fluid can be caused, can not accurately measure the temperature of fluid.Especially to tubule When the measurement of the high-pressure fluid temperature in diameter, thin-wall tube, straight-through support is welded on it or opens the internal screw thread insertion of minor diameter Temperature probe progress temperature measurement is extremely difficult, and the temperature measurement for managing interior high-pressure fluid is difficult point, it is therefore desirable to a kind of new survey High-pressure fluid temperature device in buret.
Summary of the invention
The present invention is to solve the problems, such as to manage interior high-pressure fluid thermometric, and provide high-pressure fluid temperature dress in the new measurement pipe of one kind It sets.
To achieve the goals above, the specific technical solution that the present invention takes is as follows:
High-pressure fluid temperature measuring equipment in a kind of pipe, including armoured thermocouple, armoured thermocouple screw, inner nut support, reality Test section is tested, the through-hole that can be used for across armoured thermocouple, armoured thermocouple screw centre drill are drilled on the internal screw thread support There is pore, the armoured thermocouple screw fixed seal connection is in inner nut support, and the armoured thermocouple is through internal screw thread branch The through-hole of seat 2 is deep from the lower part of armoured thermocouple screw insertion pore 1.5-2.5mm, and the conducting wire of armoured thermocouple is from pore top Portion is drawn, and high pressure resistant insulation glue is filled in the gap between the armoured thermocouple, conducting wire and the pore of armoured thermocouple screw The pore of armoured thermocouple, conducting wire and armoured thermocouple screw is bonded as an entirety;The inner nut support loading test It tests in the hole on pipeline section, and is fixedly connected by welding manner with experiment test pipeline section, and make armoured thermocouple temperature-sensitive end Directly contacted with highly pressurised liquid.
Further, the gap between the armoured thermocouple screw and inner nut support passes through intefused tetratiuorine gasket and tetrafluoro Raw material band, it is thermally conductive between armoured thermocouple screw screw and inner nut support to reduce, play sealing and function of heat insulation.
Further, the through-hole on the internal screw thread support, the aperture at the 2mm of through-hole upper end are Φ 1.2mm, lower section Aperture is Φ 1.5mm, armoured thermocouple can be made to be suspended on internal screw thread support, thermocouple temperature sensitive end directly connects with highly pressurised liquid Touching, can accurately measure the temperature of highly pressurised liquid.
Further, the outside of the armoured thermocouple screw and internal screw thread support is enclosed with insulating layer, can reduce in senior executive The rib effect of high-pressure fluid temperature measuring equipment reduces heat loss, guarantees that thermometric is accurate.
Beneficial effects of the present invention:
The present invention can be used for the thermometric of high-pressure fluid in pipe, especially suitable for the high-pressure fluid in small diameter tube, thin-wall tube Thermometric.By experimental test verification, high-pressure fluid is not leaked, and thermometric is accurate, is high-pressure spray body temperature in the new measurement pipe of one kind Spend device.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of temperature measuring device in high-pressure fluid line of the invention.
Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
As shown in Figure 1, high-pressure fluid temperature measuring equipment in a kind of pipe, comprising: armoured thermocouple screw 1, inner nut support 2, Tetrafluoro spacer 3, tetrafluoro raw material band 4, experiment test pipeline section 5, protection wire spring 6, conducting wire 7, armoured thermocouple 8, insulating layer 9.
The through-hole that can be used for across armoured thermocouple is drilled on internal screw thread support 2,1 center of armoured thermocouple screw is drilled with carefully Hole, through-hole of the armoured thermocouple 8 through internal screw thread support 2 is deep from the lower part of armoured thermocouple screw 1 insertion pore 1.5-2.5mm, Optimal deep for 2mm, the conducting wire 7 of armoured thermocouple is from 1 Base top contact of armoured thermocouple screw, armoured thermocouple 8, conducting wire 7 and armour The gap filling high pressure resistant insulation glue filled between the pore of thermocouple screw 1 is bonded as an entirety, is placed in inner nut In support 2, the gap between armoured thermocouple screw 1 and inner nut support 2 passes through intefused tetratiuorine gasket 3 and tetrafluoro raw material band 4, It is thermally conductive between armoured thermocouple screw screw 1 and inner nut support 2 to reduce, play sealing and function of heat insulation.Interior spiral shell In hole on female 2 loading test of support test pipeline section 5, it is connected and fixed by welding manner.It is worn from 1 top of armoured thermocouple screw Protection wire spring is cased on conducting wire out
The through-hole that can be used for across armoured thermocouple is drilled on internal screw thread support 2, the aperture at the about 2mm of through-hole upper end Aperture for Φ 1.2mm, lower section is Φ 1.5mm, is suspended in armoured thermocouple on internal screw thread support 2,8 temperature-sensitive of armoured thermocouple End is directly contacted with highly pressurised liquid, can accurately measure the temperature of highly pressurised liquid.
