| titleOfInvention | A kind of two eccentric throwing rod-type bleeder |
| abstract | A kind of two eccentric throwing rod-type bleeder, include bleeder housing, bleeder housing central section is provided with a radial stepped hole, and stepped hole is provided with cuts off pin; Bleeder housing and cutting off between pin is sealed by O type circle and copper washer, and the outer end of cutting off pin is fixed by back-up ring; Cut off pin outside and be provided with a groove; Bleeder housing upper is provided with conical hole; Bleeder housing central section is provided with centre bore, and bleeder lower housing portion is provided with screwed hole; During normal mining operations, two bias is thrown rod-type bleeder and is connected between pump barrel and standing valve assembly, relies on the double sealing structure of self to ensure that mining operations carries out smoothly; When inspection pumps up tubing string operation, after piston plays flowline, hit cut off pin end recesses position through adding disconnected bar to well head, it is made to rupture from groove position, and then make to be interlinked to the outside in oil pipe by pin-and-hole, liquid in pipe flows to outside pit shaft, reaches the object of smooth draining; Have that structure is simple, easy to operate, draining is reliable and reusable feature. |
