Embodiment
With reference to Figure of description 1, liquefied petroleum gas tank emptier of the present utility model is described in detail below.
Liquefied petroleum gas tank emptier of the present utility model, its structure comprises above-ground storage tank 8 and tank car 16, on described above-ground storage tank 8, be provided with the storage tank gas valve 7 being fixedly connected with storage tank gas phase pipe, described storage tank gas phase pipe is arranged in above-ground storage tank 8, the bottom of described above-ground storage tank 8 is provided with storage tank bottom tube 9, described storage tank bottom tube 9 is connected with high pressure catheter 13, between storage tank bottom tube 9 and high pressure catheter 13, be provided with former loaded check valve 12, described tank car 16 tops are provided with tank car tank 1, on tank car tank 1, be provided with tank car gas valve 2 and tank car liquid phase valve 15, between the storage tank gas valve 7 of above-ground storage tank 8 and the tank car gas valve 2 of tank car tank 1, be provided with compressor 5 and motor 4, described compressor 5 is connected with motor 4, the suction port place of compressor 5 is provided with compressor inleting pipe 3, the other end of described compressor inleting pipe 3 is connected with tank car gas valve 2, the exhaust ports of compressor 5 is provided with compressor exhaust pipe 6, the other end of described compressor exhaust pipe 6 is connected with storage tank gas valve 7, newly-increased three-way pipe 11 on described storage tank bottom tube 9, and be fixedly connected with newly-increased valve 10 at the other end of three-way pipe 11, being fixedly connected with newly-increased high pressure catheter 14 at the other end of newly-increased valve 10, the other end of newly-increased high pressure catheter 14 is connected with tank car liquid phase valve 15.
