Abstract
The utility model discloses a pluggable low thermal capacity sealing temperature probe. A lug boss is arranged in the middle of an excircle of a socket of the sealing temperature probe; threads are formed at two ends of the lug boss; and the upper end of the socket is fixed with a substrate. A probe rod is in a hollow cylinder; two lug bosses are respectively arranged at the upper and lower ends of the probe rod and are in respective threaded connection with a plug and a temperature-measuring probe. A probe rod locking nut penetrates through the probe rod and is fixed with the thread at the lower end of the socket; the probe rod is in a conical cavity; a temperature sensor is arranged in the cavity; a lead of the sensor is welded with an inner core of the plug; and the lead is connected to an external temperature display device through the socket. For realizing the strict sealing, sealing rings are respectively mounted on the excircle of the lug boss of the socket, the lower end face of the lug boss at the upper end of the probe rod and the surface in contact with the contact in the lug boss at the lower end of the probe. The probe rod is made of non-metal material; and the probe is made of metal material with high heat-conducting coefficient, thus the thermal capacity is quite low. The device is quite convenient to detach and replace, so that temperature sensors in different temperature grades can be arranged in the probe according to the requirement for temperature-measuring precision.
Description
Technical field
The utility model relates to a kind of sealing temperature measuring equipment of mechanical connect-disconnect structure mode.
Background technology
Temperature probe can be applicable to a plurality of fields, and its frame mode is also varied.The temperature probe that generally uses mainly is divided into fixed and portable two big classes on macroscopic view at present, requires to segment according to temperature measurement accuracy again.Fixed generally feeler lever and probe segment being fixed on needs space, the inside and outside of thermometric, and portable then can carrying in real time monitored.But need temperature measuring equipment is placed in the liquid in some field, liquid has corrosivity even; Also there is the thermometric requirement of different accuracy in some field according to different thermometric positions, perhaps requires to take into account fixed and portable two kinds of thermometric modes, to make things convenient for production monitoring.The existing in addition comparatively cheap temperature probe of price exists certain thermal capacity, causes temperature detection value and actual value to exist time-delay or deviation.The temperature measuring equipment that the utility model proposes can also make the problem of aforementioned existence obtain satisfied solution except the advantage that can keep above-mentioned temperature probe.
Summary of the invention
The purpose of this utility model is that a kind of seal temperature probe of plug-in low heat capacity is provided.
Followingly illustrated with reference to 1～2 pair of structural principle of the present utility model of accompanying drawing.The seal temperature probe of plug-in low heat capacity has: socket, plug, substrate, probe locknut, probe rod, temperature sensor, lead-in wire, O-ring seal etc.Be provided with boss at socket cylindrical middle part, the boss two ends are provided with external thread.Socket upper end can be passed any substrate (as the wall of any material or pipeline etc.) and fix by nut and set boss.Feeler lever is a hollow cylinder, and upper and lower two terminations of feeler lever are equipped with boss, are processed with internal thread in two boss.The boss of feeler lever upper end with have externally threaded plug and be connected; The boss of feeler lever lower end with have externally threaded probe (test lead) and be connected.The feeler lever locknut is worn the screw thread of (cover) mistake feeler lever and socket lower end and is fixed.Probe is the cavity of a taper, at temperature sensor of conical cavity internal fixation, and the lead-in wire of temperature sensor and the welding of the inner core of plug, plug is connected to lead-in wire by socket and is located at outside temperature display meter.In order to reach good sealing effectiveness, O-ring seal is housed at three positions.First the cylindrical in hub boss, promptly the feeler lever locknut is equipped with O-ring seal with the place that (fixed socket) substrate is connected; Second in the lower surface of feeler lever upper end boss, and promptly boss is equipped with O-ring seal with the place that the feeler lever locknut is connected; The 3rd is equipped with O-ring seal with the surface of contact (top of probe) of probe in the boss bottom at feeler lever.Therefore this temp probe can be placed in any liquid, and inside can not suffer erosion.The low heat capacity structural principle embodies: at first feeler lever adopts nonmetallic materials, and it has very high thermal resistance; The second, in order at utmost to reduce thermal capacitance, temperature sensor is contained in the hollow cavity of a taper, and fixing with high heat conduction soft material encapsulation, this conical cavity integral body is as the thermometric induction end.Conical cavity adopts the metal material of high thermal conductivity coefficient, and cavity do smaller.
Characteristics of the present utility model and beneficial effect be, compares with existing temp probe because the probe thermal capacitance is less, can obviously improve the time-delay and the deviation of temperature detection value and actual value existence, in addition also has following characteristics:
(1) temp probe together with feeler lever can extended immobilization on equipment, lead-in wire can long-rangely be connected to controller, also the carried terminal Displaying Meter has fixing and portable double effects to on-the-spot thermometric as required.
(2) feeler lever is nonmetallic materials, and is anticorrosive; Though probe is a metal material, so volume is less cheap.
(3) triple seal design, temp probe inside can not be subjected to corroded by liquid.
(4) because this device dismounting and change is very convenient, so can the temperature sensor of different accuracy grade be set in probe according to the requirement of temperature measurement accuracy.
