An explosion-proof heating device
ActiveCN103634951BEasy to passWon't cause tanglingOhmic-resistance heatingMaterial electrochemical variablesEngineeringThermocouple
The invention discloses an explosion-proof heating device which comprises a heating controller, a connecting wire, a heating component and an electrochemical sensor. The heating controller is connected with the heating component through the connecting wire. The electrochemical sensor is disposed on the upper portion of the heating component. The explosion-proof heating device further comprises a thermocouple which is disposed inside the heating component. The heating controller judges whether to supply power to a heating strip in the heating component for heating or not according to the temperature fed back by the thermocouple disposed in the heating component. The explosion-proof heating device has the advantages that certain temperature around the electrochemical sensor can be kept, and electrochemical sensor detecting equipment can effectively detect the concentration of poisonous and harmful gases and give out alarms; whether heating is needed or not can be judged accurately to save resources; the heating component is of a reasonable integral structure; the deep thread structure of the inner wall of a heat guide pipe facilitates heat transferring; a locking sleeve is used as a connecting part, and safety and reliability are achieved; a blown fuse is used as the secondary guarantee of the heating device, and explosion accidents can be prevented.

Design method of rotatable pressure switch with limiting device
The invention discloses a design method of a rotatable pressure switch with a limiting device, and belongs to the technical field of pressure sensor packaging processes. The method comprises the following main process steps: a shell part is connected with a stop part in a welding manner; the shell part slides to the process part through the gap, the shell part and the process part rotate relativeto each other, and the sealing ring ensures that the connection of the shell part and the process part is impermeable to water; a columnar part is fixed to the non-center position of the process partin a threaded connection mode, and when the shell part rotates relative to the process part, it is ensured that the columnar part makes contact with the stop part so as to limit the maximum 360-degreerotating movement of the shell part and the process part. The design method has the advantages that: (1) the pressure switch is rotatable, so that data on the pressure switch display can be read conveniently; and (2) the maximum rotation angle of the pressure switch is 360 degrees, so that internal wires cannot be wound, and the service life is prolonged;
