Furthermore, all be equipped with the tight bolt in multiunit top around first seal box and the second seal box, be equipped with the packing pressure disk between graphite packing top and the second seal box.
The beneficial effect of this application does:
1. set up first seal box and second seal box and increased the inner space of first seal box, second seal box, use double-deck sealed square iron and three-layer graphite packing, through many times of experiments, it is sealed effectual, hardly any reveals, increases sealed effect.
2. After the graphite packing is worn and torn, it and the clearance grow between the piece of pushing head can influence sealed effect, if do not increase packing pressure disk and puller bolt, can only change the graphite packing, and can compress tightly the packing again after increasing and need not change, just so saved vulnerable part and workman's maintenance intensity.
3. The device of the gas circuit blowback of contrast file among the background art has been cancelled, and the gas circuit blowback leads to the increase of sealed box malleation owing to additionally increase high-pressure gas to sealed box is inside at the field usage in-process, has increased the raise dust to a certain extent, and the blowback gas circuit has supporting electrical apparatus part in addition, has increased the unstable structure and has maintained intensity to a certain extent.
