Description

A kind of plug-in type NTC temperature sensing device
Technical field
This utility model is related to a kind of temperature sensing device, and in particular to a kind of plug-in type NTC temperature sensing device.
Background technology
Current NTC temperature sensors when in use, needs temperature sensor is welded, or screw fix, or cover after The modes such as encapsulation with treat fluid measured or fluid line and be in close contact to reach detection temperature purpose.Similar mounting means is complicated, Trouble is changed, and is easily caused temperature sensor damage.
Utility model content
For solving the above problems, this utility model provides one kind and installs and change simple, rapid, and non-damageable slotting Enter formula NTC temperature sensing device
This utility model provides following technical scheme:A kind of plug-in type NTC temperature sensing device, including cylinder The temperature sensor of type NTC;Cylinder type NTC temperature sensors include that one end is closed, the cylindrical case of one end open, temperature-sensitive Resistance, epoxy resin and wire;Critesistor arranges blind end inside the housing, after being connected with wire, by epoxy resin entirety It is enclosed in shell;It is characterized in that:Also include three-way piece, at least one opening is provided with quickly in three openings of three-way piece Joint;Snap joint includes sealing ring and deck.
As further improving, endless groove is provided with the outer surface of outer cover of NTC temperature sensors, on deck Convex portion coordinates.
Used as a kind of optimization, the outer surface of outer cover of NTC temperature sensors is rough surface.
The utility model because employing plug-in type NTC temperature sensing device, install and change letter by temperature sensor It is single, quick, and be hardly damaged.
Description of the drawings
Fig. 1 is sectional view after the decomposition of this utility model plug-in type NTC sensing device.
Specific embodiment
Below in conjunction with the accompanying drawings to this utility model as further detailed description.
As shown in figure 1, the plug-in type NTC temperature sensing device, including cylinder type NTC temperature sensors 1 and three Logical part 2;Cylinder type NTC temperature sensors 1 include that one end is closed, the cylindrical case 11 of one end open, critesistor 12, ring Oxygen tree fat 13 and wire 14;Critesistor 12 is arranged on 11 inside blind end of shell, after being connected with wire 14, by epoxy resin 13 Integrally closed is in shell 11;Three openings of three-way piece 2 are both provided with snap joint, or only pass in insertion NTC temperature The opening of sensor 1 is provided with snap joint;Snap joint includes sealing ring 21 and deck 22.
When the plug-in type NTC temperature sensing device is installed, first external pipe 3 is inserted two openings of three-way piece 2 In, after being fixed by snap joint or stickup, then another opening for NTC temperature sensors 1 being inserted with snap joint In.When flowing through in fluid from outside pipeline 3 and three-way piece 2, NTC temperature sensors 1 can touch fluid, measure stream Temperature.If NTC temperature sensors 1, only need to be with handss to 2 direction of three-way piece because damaging or when other reasons need to change Pressure deck 22, you can NTC temperature sensors 1 are quickly extracted, then new NTC temperature sensors 1 are inserted i.e. Can.
Can be coordinated with the convex portion 221 on endless groove 111, with deck 22 being arranged on 11 outer surface of shell, can avoid N TC temperature sensors 1 are deviate from from three-way piece 2.
For avoiding NTC temperature sensors 1 from deviating from from three-way piece 2, it is also possible to the outer of NTC temperature sensors 1 11 outer surface of shell makes rough surface, the frictional force of the convex portion 221 in increase and deck 22.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but this utility model is not limited to Above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can be with without departing from this utility model Make a variety of changes on the premise of objective.
