Brief description of the drawings
Fig. 1 embodiment of the present invention structural representation.
Detailed description of the invention
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, the present invention relates to a kind of without lubricating cup self-desiccation respirator, comprise the breather tank 1 that is equiped with drier 2, in described breather tank 1, be installed on the respiratory siphon 3 being connected with oil-charging type electrical device pipeline, described respiratory siphon runs through breather tank, described respiratory siphon comprises and is positioned at the air-guide section of breather tank and is positioned at the free segment outside breather tank, respiratory siphon lower end the first spring reset assembly that is positioned at free segment is connected with a respiratory siphon shrouding 4, one side of the bottom of described breather tank is provided with exhaust outlet 5, opposite side is provided with air inlet 6, on described exhaust outlet, be connected with exhaust outlet shrouding 7 through the second spring reset assembly that is positioned at breather tank outside, on described air inlet, be connected with air inlet shrouding 8 through the 3rd spring reset assembly that is positioned at breather tank inside.
In above-mentioned breather tank, be also provided with the electric heating assembly 9 of a circle in order to bake drying agent.
Above-mentioned the first spring reset assembly comprises that two symmetries are spirally connected and the first adjusting bolt bar 10-1 of respiratory siphon lower end, two first described adjusting bolt bars are slidably connected with one end of respiratory siphon shrouding respectively, and between the termination of respiratory siphon shrouding and the first adjusting bolt bar, be provided with the first back-moving spring 10-2, the first back-moving spring under normality covers on respiratory siphon lower end respiratory siphon shrouding; Described the second spring reset assembly comprise two symmetries be spirally connected with exhaust outlet bilateral breathing pot bottom on the second adjusting bolt bar 11-1, two second described adjusting bolt bars are slidably connected with one end of exhaust outlet shrouding respectively, and between the termination of exhaust outlet shrouding and the second adjusting bolt bar, be provided with the second back-moving spring 11-2, the second back-moving spring under normality covers on breather tank exhaust outlet exhaust outlet shrouding; Described the 3rd spring reset assembly comprise two symmetries be spirally connected with air inlet bilateral breathing pot bottom on the 3rd adjusting bolt bar 12-1, two the 3rd described adjusting bolt bars are slidably connected with one end of air inlet shrouding respectively, and between the termination of air inlet shrouding and the 3rd adjusting bolt bar, be provided with the 3rd back-moving spring 12-2, the 3rd back-moving spring under normality covers on breather tank air inlet air inlet shrouding.
