Abstract
The utility model relates to a heat probe, belonging to the technical field of temperature sensors, which mainly solves the problem of the twisting of the external leads extending out from the middle rear in the process of installation. The adopted technical scheme is that: the heat mainly consists of a thermistance, a connecting wire and a collar with outside thread. The thermistance and a lead connected with the thermistance are positioned in a probe case. The thermistance is arranged on the front of a probe case and the lead extends to the external probe case. Ring-shaped sockets which prevent the thermistance from moving along axial direction are arranged on the outer surface of the probe case. Keyseats are arranged on the inner wall of the collar and perpendicular to the axial direction. Dowels are arranged in pinholes formed at a position where the collar and the ring-shaped sockets correspond. An O seal ring is arranged on one end face of the collar at a position close to the thermistance. The utility model can be widely used in the systems of heat supply and air conditioning.
Description
(1) technical field
The utility model relates to a kind of Heat probe, belongs to the temperature sensor technical field.
(2) background technology
At present, on for the pipeline in dim facility or the air-conditioning system, usually Heat probe need be set, be beneficial to the control of heat or temperature.And existing Heat probe be mostly will probe thermistor and have the externally threaded collar and be fixed as one, the lead that is connected with thermistor extends the outside of the collar.With piping erection the time, the external thread by the collar cooperates with pipeline to be tightened.The problem of this sonde configuration is: when the collar and pipeline were tightened fixedly, thermistor and the lead that is attached thereto rotated simultaneously, the lead distortion were twined, for follow-up work is made troubles.
(3) technology contents
Technical problem to be solved in the utility model is to propose a kind of Heat probe rational in infrastructure, and the lead distortion that can avoid pops one's head in draws is twined, and helps that follow-up everything goes well with your work carries out.
The related Heat probe of the utility model is mainly by thermistor, connect lead and have the externally threaded collar and constitute, thermistor and the lead that is attached thereto are positioned at a probe sheath, thermistor is positioned at the front end of probe sheath, lead extends to the probe sheath outside, radially be processed with at the outside surface of probe sheath and prevent the annular groove of thermistor along the axis direction play, have cotter way at the inwall of the collar perpendicular to axis direction, pin is installed in the pin-and-hole of cotter way and the formation of annular groove corresponding position, and the collar is equipped with " O " shape O-ring seal near the end of thermistor one end.
The position that is positioned at probe sheath for the maintenance thermistor is more firm, radially is processed with twice or the annular groove more than the twice at the probe sheath outside surface.
The thermistor that is adopted in above-mentioned Heat probe is a platinum resistance.
Probe sheath is a copper sheathing, and the surface is coated with antirust coat.
For making things convenient for lead sealing, radially have groove at the collar near the appearance of lead elongated end, make this end form the flange plate-like, can get axial lead seal hole at the dish end face.
The utility model when mounted, similar to existing probe installation, tighten installation by the collar and pipeline threaded engagement, or be installed on the by-pass valve control place in the pipeline, promptly have threaded hole, Heat probe is fastened on the valve place that flow of liquid is crossed by threaded engagement at the valve place.The utility model is in installing rundown process, because the collar and probe sheath are located by connecting by pin, therefore tighten in the rotation process at the collar, probe does not rotate thereupon, it is along the circumferential direction mobile in the annular groove of probe sheath that only pin is followed the collar, make probe sheath tightening and move axially like this with the collar, do not rotate, therefore the distortion of having avoided extending the probe sheath outer lead is twined, not only Heat probe is easy for installation, give follow-up work simultaneously, as: probe brought convenience with being connected of other instruments, equipment, increased work efficiency.
(4) description of drawings
Fig. 1 is a structural drawing of the present utility model.
(5) embodiment
Embodiment
Heat probe as shown in the figure, mainly by lead 1, the collar 2, probe sheath 5, and thermistor 6 constitute, the collar 2 has external thread, thermistor 6 is a platinum resistance, thermistor 6 and the lead 1 that is attached thereto are positioned at the front end of probe sheath 5, and lead 1 extends outside the probe sheath 5.For thermistor being stable in the inside of probe sheath 5, be extruded with the annular groove 7 that twice concave at probe sheath 5 outside surfaces, form inside closing in by annular groove 7, lead 1 can not be broken away from probe sheath 5.Have cotter way perpendicular to axis direction on the internal ring wall of the collar 2, pin 3 is for selling directly to households, pin 3 is installed in the pin-and-hole of cotter way and the formation of concave grooves 7 corresponding positions, the collar 2 and probe sheath 5 are located by connecting, front end at the collar 2 is equipped with " O " grommet type seals 4, to play sealing, prevent the effect of fluid seepage.For helping heat conduction and prevent corrosion, probe sheath 5 is made by copper material, is coated with nickel anti-corrosion layer on its surface.Outer surface near the collar 2 has groove 8, at the blue shape of outboard end forming method, helps axially beating lead seal hole on the dish of this flange-like, and lead sealing is installed.
This Heat probe is when using, use similar to existing Heat probe, can be installed on by special reduced tee in the pipeline, can also be installed on the flow control valve, as: the flow control ball valve, can improve ball valve, will be on the ball valve processing one threaded hole, the external thread of Heat probe by the collar 2 cooperates with threaded hole Heat probe is fixed on the ball valve.Because in installation process, when the collar 2 rotates, pin 3 moves in the annular groove 7 of probe sheath 5, probe sheath 5 is not rotated with the collar 2, only constantly tighten and axially in pipeline, move along with the collar 2, therefore can avoid the mutual winding of lead 1, the convenient lead 1 that passes through connects in other testing apparatuss.Can change Heat probe easily if close ball valve.
Above-mentioned Heat probe can be widely used in heating, heating system and the air-conditioning system.
Claims (5)
1. Heat probe, mainly by thermistor, connect lead and have the externally threaded collar and constitute, thermistor and the lead that is attached thereto are positioned at a probe sheath, thermistor is positioned at the front end of probe sheath, lead extends to the probe sheath outside, it is characterized in that: radially be processed with at the outside surface of probe sheath and prevent the annular groove of thermistor along the axis direction play, have cotter way at the inwall of the collar perpendicular to axis direction, pin is installed in the pin-and-hole of cotter way and the formation of annular groove corresponding position, and the collar is equipped with " O " shape O-ring seal near the end of thermistor one end.
