| titleOfInvention | A kind of hydraulic inner cutter for deep-sea Casing-Cutting |
| abstract | The utility model relates to a kind of hydraulic inner cutter for deep-sea Casing-Cutting, belongs to oil, natural gas casing repairing technical field of tools.It is made up of housing, cutter assembly, piston assembly etc., and be characterized in: housing two ends are separately installed with piston assembly, lower contact, housing central section is provided with cutter assembly; Outside housing, centralizer is installed; All open in the middle of piston assembly, in the middle of lower contact and be shaped with runner; Embeddingly on the cutting edge of cutter hub be shaped with carbide alloy, cutter hub end both sides are provided with flat spring by bearing pin; Valve disc center is opened and is shaped with centre bore, and its circumference is manufactured with aperture; Piston and valve disc are located by connecting by cylinder sleeve, are provided with spring between piston and housing.Cutter hub hardness is high, long service life; Cutter hub is regained freely, guarantees cutter hub operation placed in the middle, and structure is simple, and easy to operate, cutting efficiency improves greatly; Solve existing cutter hub and regain difficulty in housing, cutter hub hardness is poor, and application life is short, and structure and complicated operation, very easily there is the problem of cutting accident. |
