Abstract
The utility model relates to a high pressure fluid precision temprature measuring device which mainly consists of a metal-shielding thermocouple, a hollow bolt, a sleeve, a support base, a hollow tetrafluorin column, etc. The hollow tetrafluorin column is arranged outside the metal-shielding thermocouple and the sleeve, and screwed tightly with the support base with a screw thread through the hollow bolt, so that the hollow tetrafluorin column is deformed, which achieves good result in sealing the high-pressure liquid. The heat conduction between the thermocouple and the sleeve wall is avoided so that the measuring accuracy is high. The experiment shows that the device can afford a pressure as much as 120kgf/cm<2>. The utility model is simple is structure, with the thermocouple capable of be disassembled and replaced at any moment, and is in particular applicable for the temperature measurement for the high-temperature and high-pressure liquid in the pipes with small diameters.
Description
The utility model belongs to temperature measuring equipment.
For the measurement of temperature,, can be divided into contact and contactless two big classes at present according to measuring method.Adopt contactless temperature-measuring for fluid temperature (F.T.), owing to be subjected to the influence or the restriction of a variety of causes, measuring accuracy is poor slightly, generally adopts contact temperature-measuring.For the measurement of tube fluid temperature, the greatest problem of existence is: when adopting thermopair directly to measure, need punch on tube wall passing thermopair, and then hole is sealed up.The method inevitably can make the point for measuring temperature of the temperature effect of wall to thermopair (tip), and measured temperature is fluid and the comprehensive effect that influenced by pipe surface temperature, and the true temperature of nonfluid.If its influence degree of armoured thermocouple can be bigger.In order to improve the thermometric accuracy, can install thermal insulation material additional on the thermopair surface, but this is applicable to the low pressure situation.The leakage of fluid (especially gas) when pressure improves, can occur,, change very difficulty of thermopair except that solving the sealing problem.Therefore, for the measurement of middle low temperature, high-pressure fluid, be badly in need of a kind of novel temperature measuring equipment to improve precision.
The purpose of this utility model provides a kind of high pressure resistant, high-precision temperature measuring equipment.
The utility model adopts contact type measurement, can get rid of the influence of wall temperature to measuring point, effectively improves the level of dut temperature near true temperature.Its apparatus structure as shown in drawings.
The accurate temperature measuring equipment of high-pressure fluid, by armoured thermocouple (1), hollow screw (2), sleeve pipe (3), bearing (4), hollow tetrafluoro cylinder compositions such as (5).Hollow tetrafluoro cylinder (5) is enclosed within the outside of armoured thermocouple (1) and sleeve pipe (3), tighten fixing by hollow screw (2) and the bearing (4) that has internal thread, make hollow tetrafluoro cylinder (5) be out of shape, length reduces, width increases, and makes high-pressure fluid and temperature measuring equipment reach excellent sealing effect.Completely cut off the heat conduction between thermopair and the tube wall simultaneously, guaranteed the accuracy of measuring.The internal thread degree of depth of bearing (4) is greater than the hollow screw reach.Overall dimensions can be done respective change according to the diameter of armoured thermocouple.The utility model also can match with read out instrument or computer-automatic collection system, makes to measure easily simply, and can realize that transient state measures in real time.
During installation according to the concrete condition of fluid channel structure and shape, the bearing (4) that at first will have internal thread is welded on the fluidic channel walls (6), sleeve pipe (3) is inserted in armoured thermocouple (1), penetrate hollow screw (2), hollow tetrafluoro cylinder (5) then successively, be inserted into again on the bearing (4), the most advanced and sophisticated measuring point of armoured thermocouple (1) is exposed in the detected fluid.Tighten hollow screw (2), make hollow tetrafluoro cylinder distortion tightly to choke the space between thermopair and the bearing, reach sealing purpose.The deflection of common hollow tetrafluoro cylinder (5) is 2～4mm.Improve withstand voltage degree if desired, can not will sleeve pipe is whole is enclosed within on the armoured thermocouple, only the part that contacts with bearing at thermopair puts and gets final product, the through hole of hollow like this tetrafluoro cylinder just can dwindle, and can improve compressive resistance.Sleeve pipe (3) and hollow tetrafluoro cylinder (5) can adopt high temperature resistant, high pressure resistant, resistant material making such as teflon.Hollow screw (2) and bearing (4) can adopt stainless steel or other nonmetallic materials according to the material in logical (pipe) road (6) of fluid.
The utility model is simple in structure, the accuracy of measurement height.And convenient disassembly can be changed thermopair at any time, is particularly useful for measuring the fluid temperature (F.T.) in the little caliber.Through measuring, the utility model can withstand voltage 120kgf/cm
2Can be used for the equipment of industrial product, scientific research and experiment device for teaching etc.
