The inside of liquid storage shell is stated filled with mineral oil, the outer surface of the temperature sensor is fixedly arranged above aerial drainage set, the aerial drainage set
Outer surface be connected with spiral leak-off pipe, the lower inside of the liquid storage shell is fixed with the second sealing ring, the temperature sensor
Top be fixed with temperature-sensitive head.
Preferably, the spiral leak-off pipe is provided with four, and four spiral leak-off pipes are arranged in " ring-shaped "
The outer surface of aerial drainage set.
Preferably, the conical pipe is adapted with shell, and the outer surface of the conical pipe is socketed with the first sealing ring.
Preferably, the base diameter of the liquid storage shell is greater than the top diameter of conical pipe.
Preferably, the overhead height of the mineral oil is greater than the overhead height of aerial drainage set.
Preferably, the spiral leak-off pipe runs through liquid storage shell, and the spiral leak-off pipe and aerial drainage set weld.
Compared with prior art, the utility model has the beneficial effects that the temperature sensor assembly, be provided with conical pipe,
Screw thread, the first sealing ring, the second sealing ring, aerial drainage set, spiral leak-off pipe, and spiral leak-off pipe is obliquely installed, when in use, work
Make personnel to be fixed on by temperature sensor through liquid storage shell and by conical pipe below the outer surface of temperature sensor, then rotating cone
Shape pipe, is threadedly coupled it with shell, and the first sealing ring is fixed between conical pipe and shell under the action of screw thread, makes it
Sealing, prevents natural gas from corroding, during detection, since spiral leak-off pipe is obliquely installed, it is straight to avoid natural gas air pressure
Effect is connect, mineral oil can be made to flow out, prevents mineral oil from thermally expanding extrusion damage temperature sensor, solves installation process sealing
Circle can misplace, and cause natural gas damage temperature sensor, temperature sensor disassembly installation inconvenience and leak-off pipe to be vertically arranged, day
The problem of will cause mineral oil when so gas air pressure is excessively high cannot exclude, and mineral oil thermal expansion squeezes temperature sensor.
