Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
A multistage quantitative hole sealing device for pressure relief drilling is disclosed, as shown in fig. 1, fig. 2 and fig. 3, and comprises a housing 1, an end cover 2, a traveling shaft 3 and a piston 4, wherein the end cover 2 is fixedly installed on the top of the housing 1, the bottom end of the traveling shaft 3 penetrates through the end cover 2 and extends into the housing 1, the piston 4 is fixedly connected with the end cover, the piston 4 is rotatably and translatably arranged in the housing 1, the top of the traveling shaft 3 is provided with an installation disc 301 connected with an external propulsion device, a cleaning channel is formed in the traveling shaft 3 and can introduce cleaning water into the housing 1, a limiting strip 303 is arranged on the shaft body of the traveling shaft 3 in an array manner, three limiting discs 101 are fixedly arranged in the housing 1 at intervals, the intervals between the limiting discs 101 are the same, through holes 1011 for the traveling shaft 3 to pass through are formed on the limiting discs 101, and through grooves 1012 for the limiting strip 303 to pass through are formed on the limiting discs 101, when different limiting discs 101 are installed, the installation angles of the limiting discs passing through the grooves 1012 are different, so that the limiting strips 303 need to rotate when passing through.
In this embodiment, as shown in fig. 1, a hole-sealing injection port 103 is disposed at the bottom of the housing 1, a feed port 102 is disposed on a side wall of the housing 1, and a sliding bearing 201 is fixedly disposed at a passing position of the end cover 2 on the traveling shaft 3.
