If the explosion-proof electric device in the case of short circuit fault, electric device burned out, there will be no spark, in the production process, the winding of explosion-proof electric device and ordinary electric device is not the same, so this is a big advantage of explosion-proof electric device. Explosion-proof electric device is suitable for working in coal mine, flammable and explosive environment. Objectively, many industrial sites meet explosion conditions. When the concentration of the mixture of explosive substance and oxygen is within the explosive limit range, if there is an explosive source, an explosion will occur. Therefore, it is necessary to take explosion-proof measures.
In the standard of explosion-proof actuator, the effective length of the sealing surface of the window and the sealing surface of the actuator shell in the products with internal space less than 500ml should be greater than 9.7mm. At present, the keys are mostly conductive rubber, which cannot meet the requirements of the sealing surface length of explosion-proof products. If waterproof keys are used, the keys themselves are larger and occupy larger space. It is not easy to achieve this type of key structure which can be waterproof from the outside and sealed from the inside to the outside in a small space.
In order to solve the above mentioned problem, manufacturer provides a simple structure, sensitive buttons, volume is small and exquisite save area, easy to realize explosion-proof electric actuators key structure.
The key structure of the explosion-proof electric actuator includes the shell, the upper key, the press column and the conductive key. It has the following advantages and positive effects:
1, explosion-proof electric actuator of the key structure of the key and conductive key installation structure is reasonable, uniform force of the key, flexible operation, and high tightness, in line with the national provisions of waterproof, explosion-proof requirements.
2. The key press column in the key structure of the explosion-proof electric actuator is metallic material, which has enough strength and high flame retardant. By coating a layer of lubricating oil on the outer surface of the key press column, it not only improves the lubrication performance, but also prevents electrochemical corrosion.
3. The key structure of explosion-proof electric actuator is simple, the design is scientific and reasonable, the idea is ingenious, and it is easy to realize. The appearance is beautiful, the size is small, and it has the value of wide popularization and application.
