Further, the heat conducting pipe is copper heat conducting pipe.
Screw carburetor temperature detect switch (TDS) of the present invention is moved forward and backward using the drive screw rod that expands with heat and contract with cold of air, so as to promote
Axis of rotation, is produced moment of torsion and is exported by pivoted arm, and pivoted arm drive connection bar opens or closes the air door of its carburetor.
Brief description of the drawings
Fig. 1 is the structural representation of the better embodiment of carburetor temperature switch of the present invention.
Fig. 2 is the partial sectional view of carburetor temperature switch.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the better embodiment of carburetor temperature switch of the present invention includes housing 1, rotating shaft 2, pivoted arm
3rd, screw rod 4 and heat conducting pipe 5, the heat conducting pipe 5 are located in one end of the housing 1, and one end of the screw rod 4 is located at described leading
In heat pipe 5, and screw rod 4 coordinates with the hermetic seal of heat conducting pipe 5；The rotating shaft 2 is located on the other end of the housing 1, and described
Rotating shaft 2 can be rotated relative to the housing 1, and specifically, rotating shaft 2 is fixed on the housing 1 by bearing；The rotating shaft 2
One end is arranged on the screw rod 4, and the other end of the rotating shaft 2 is fixed with one end of the pivoted arm 3, the pivoted arm 3 it is another
End is provided with the connecting hole 31 for being fixed with connecting rod.Environment temperature at 65 DEG C relative to environment temperature at 25 DEG C, rotating shaft 2 is revolved
The angle for turning is more than 40 °, and environment temperature is at 65 DEG C, and the torque output minimal torque of pivoted arm 3 is output as 0.5N mm.Its
In, heat conducting pipe 5 is copper heat conducting pipe, it is ensured that the efficiency high of heat transfer.
The housing 1 is provided with fixed block, and the fixed block is provided with fixing hole 11, and the housing 1 utilizes the fixing hole
11 fix.
The screw rod 4 includes seal disc and sets the threaded body of rod, and the seal disc is fixed with one end of the body of rod, the body of rod
The other end is connected with the rotating shaft 2.
The pivoted arm 3 is provided with the connecting hole 31 for being fixed with connecting rod with one end of the fixing phase pair of the rotating shaft 2, described
Air line distance between the axial line of connecting hole 31 and the axial line of the rotating shaft 2 is 32mm, it is ensured that the moment of torsion energy of the output of pivoted arm 3

In closed container there is following relation in temperature and pressure：
PV=nRT, wherein P are the pressure in closed container, and V is the volume of closed container, and n is the amount of material (because of something
The amount of matter is constant, it can thus be understood that constant), R is constant, and T is the temperature in closed container.N and R are constant
, when the pressure P in closed container is constant, then volume of a container V and temperature T are directly proportional, i.e., the temperature T liters in closed container
Gao Shi, the volume V increases of closed container；When temperature T in closed container is reduced, the volume V of closed container reduces.
