The following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1-3, a flame-proof type detector casing, including upper cover 1, base 5 and closing cap 18, base 5 is the open cavity structure in upper and lower end, upper cover 1 cover is in the 5 top outsides of base and is uncovered to base 5 upper end, be equipped with explosion-proof transparent observation window 7 between the roof of upper cover 1 and the 5 top surfaces of base, be equipped with the observation hole that corresponds with explosion-proof transparent observation window 7 on the roof of upper cover 1, upper cover 1 and base 5 pass through threaded connection on the lateral wall, closing cap 18 blocks on the 5 lower extreme of base is uncovered, closing cap 18 top is equipped with circuit board mounting panel 9, closing cap 18 bottom is equipped with ground screw 16, base 5 lateral wall bottom is equipped with explosion-proof cable introducing device 4.
The grounding screw 16 is stainless steel or galvanized screw, so that the antirust capacity is enhanced.
The explosion-proof cable introduction device 4 is a model a 1.
The explosion-proof transparent observation window 7 is made of sodium calcium tempered glass, not only keeps the observation function of the shell, but also has an explosion-proof function.
A red copper pad 6 is arranged between the explosion-proof transparent observation window 7 and the top plate of the upper cover 1. A sealing gasket 8 is arranged between the explosion-proof transparent observation window 7 and the top surface of the base 5, and the sealing gasket 8 is a chloroprene rubber gasket. The red copper pad 6 has good corrosion resistance, more outstanding wear resistance and pressure resistance, is particularly suitable for high-temperature and high-pressure sealing parts, can effectively prevent the scattering of the gasket and the erosion of media, and simultaneously improves the pressure resistance. And the hardness of the red copper pad 6 and the sealing pad 8 is obviously lower than that of the sodium-calcium toughened glass, so that the explosion-proof transparent observation window 7 is prevented from being damaged.
The rubber seal ring 17 is pressed between the bottom surface of the upper cover 1 and the base 5, so that the contact surface between the bottom surface of the upper cover 1 and the base 5 is prevented from being damaged due to the fact that the upper cover 1 and the base 5 are screwed too tightly, and the upper cover 1 is prevented from being difficult to take down due to the fact that the contact surface is corroded after long-time use.
