Structural schematic diagram.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments, based on the implementation in the utility model
Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all belongs to
In the range of the utility model protection.
As shown in Figure 1, the utility model embodiment provides a kind of unpowered constant current chemicals dosing plant of band casing pressure well mouth of oil well,
The chemicals dosing plant includes: grug feeding jar 1, air inlet pipe 2, aeration valve 3, is shorted 4, main valve 5, pipeline 6, threeway 7, needle valve 8, de-plugging valve
9, inlet tube 10, blowdown valve 11, liquidometer 12, pressure gauge 13, safety valve 14, dosing mouth 15, dosing valve 16 and well head header 17.
1 bottom of grug feeding jar is inserted into one end of inlet tube 10, and the other end of inlet tube 10 passes sequentially through needle valve 8, threeway 7, pipeline 6, total
Valve 5 is shorted 4 and 17 connection of well head header；Three ends of threeway 7 are connect with one end of air inlet pipe 2, needle valve 8 and pipeline 6 respectively,
Air inlet pipe 2 is connect by aeration valve 3 with threeway 7, and the other end of air inlet pipe 2 is located in grug feeding jar 1；In grug feeding jar 1 into
Tracheae 2 is " u "-shaped, and port is located at the lower part of grug feeding jar 1；Height of the air inlet pipe 2 in grug feeding jar 1 is higher than inlet tube 10 and is adding
Height in medicinal cupping 1；De-plugging valve 9 and 10 connection of inlet tube, connection mouth are located at needle valve 8 and lead on the path of grug feeding jar 1；Blowdown
Valve 11 passes through sewage pipe and 1 bottom connection of grug feeding jar；The tank skin connection of liquidometer 12 and grug feeding jar 1；Safety valve 14 and grug feeding jar 1
