Fig. 2 is the schematic diagram that anti-poisoning device of the present utility model is connected with oil transportation centrifugal pump.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, 2, the utility model provides a kind of anti-poisoning device, it is connected in the inlet line 101 of oil transportation centrifugal pump 10, described anti-poisoning device comprises discharge opeing cylinder 1 and discharge opeing cylinder top head assembly 2, wherein: a side of discharge opeing cylinder 1 is connected with feed liquor exhaust-valve 3, its opposite side is connected with liquid expulsion valve 4, and described feed liquor exhaust-valve 3, described liquid expulsion valve 4 are connected with the inlet line 101 of described oil transportation centrifugal pump 10 respectively; Discharge opeing cylinder top head assembly 2 has upper cover 21 and is connected to the float-controlled valve 22 on described upper cover 21, and described upper cover 21 is connected to the upper end of described discharge opeing cylinder 1, and the upper end of described float-controlled valve 22 is connected with gas expulsion valve 5.
Specifically, discharge opeing cylinder 1 has receiving cavity 11, and it is made up of steel material, and receiving cavity 11 is interior for carrying liquid; Feed liquor exhaust-valve 3 is connected to a side upper end of discharge opeing cylinder 1 by a pipeline 31; Liquid expulsion valve 4 is connected to the opposite side lower end of discharge opeing cylinder 1 by a pipeline 41.
The upper cover 21 of discharge opeing cylinder top head assembly 2 is bolted in the upper end of discharge opeing cylinder 1, and it is made up of steel material; The float-controlled valve 22 of discharge opeing cylinder top head assembly 2 has float valve bonnet 221 and float spool 222, float valve bonnet 221 and float spool 222 are made by steel material, float valve bonnet 221 is shaped in upper cover 21, float spool 222 is substantially spherical in shape, it is arranged in the inner chamber of float valve bonnet 221, the lower end of float valve bonnet 221 offers multiple through holes 223, it stretches in discharge opeing cylinder 1, thereby the inner chamber of float valve bonnet 221 and the receiving cavity 11 of discharge opeing cylinder 1 are connected, and the upper end of float valve bonnet 221 is connected with gas expulsion valve 5 by pipeline 51.
