Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：Oily formula vacuum pump pipeline compensator, including compensation
Device body 1, the mounting flange 3 that the compensator body 1 includes compensation pipe 2 and is fixedly mounted on the compensation opposite end of pipe 2,
The compensation pipe 2 is made up of bellows 21 and the straight tube 22 being connected on the opposite end of bellows 21, and the bellows 21 is by interior
Bellows 211 and the outward corrugated tube 212 being connected on the outside of inner corrugated pipe 211 form, the inner corrugated pipe 211 and outward corrugated tube
Waveform on 212 is consistent, and the mounting flange 3 is fixedly mounted on straight tube 22, is set respectively on the both ends of the compensation pipe 2
There are air inlet 7 and gas outlet 8, multiple threaded mounting holes 5 are provided with the mounting flange 3, be easy to compensator body 1
It is fixedly mounted in vacuum pump pipeline, firmly installs and convenient disassembly, stretching is fixedly connected between the mounting flange 3
Gag lever post 4, the stretching gag lever post 4 are made up of spring 41 and the gag lever post 42 being connected on the both ends of spring 41, the stretching limit
Gag lever post 42 on the both ends of bar 4 of position is fixedly mounted on mounting flange 3, and the spring 41 is to stretch back-moving spring, compensator
Ripple 21 and spring 41 are stretched by gas expansion in pipe when in use, so as to be compensated to vacuum pump pipeline, gag lever post 42
Bellows 21 caused by the stretching transition of bellows 21 can be avoided to rupture, when not in use, spring 41 resets, and spring 41 resets caused
