Hydraulic pressure butterfly valve shaft sleeve installation machine and installation method

The invention relates to a hydraulic pressure butterfly valve shaft sleeve installation machine and an installation method thereof, and is characterized in that the installation machine is provided with a hydraulic cylinder and a located block which are fixed on a working platform surface from right to left; a right locating pin shaft and a left locating pin shaft which are used for respectively pressing an upper valve neck shaft sleeve and a lower valve neck shaft sleeve into an upper valve neck shaft hole and a lower valve neck shaft hole, are coaxial and are arranged on the end surface of the piston rod and relative located block end surface oppositely; a right flange, a left flange, a right shoulder, a left shoulder, a right pin shaft end and a left pin shaft end are coaxially arranged on a right locating pin shaft and a left locating pin shaft in a axisymmetric manner; the width of the right shoulder and the left shoulder which are in clearance fit with the upper valve neck shaft hole and the lower valve neck shaft hole is equal to the width of a circular ring spacer bush, also is equal to the sum of the width of the upper valve neck shaft sleeve and the thickness of a circle ring; the length of the right pin shaft end and the left pin shaft end is equal to the width of the upper valve neck shaft sleeve; and the external diameters of the spacer bush, the right flange and the left flange are more than the diameters of the upper valve neck shaft hole and the lower valve neck shaft hole. The method comprises the following steps: (1) two ends of the upper valve neck shaft hole are symmetrically pressed into a built-in shaft sleeve; (2) two end ports of the upper valve neck shaft hole are pressed with the shaft sleeve; and (3) the lower valve neck shaft hole is pressed into the shaft sleeve. The installation machine has the advantages of preventing heavy physical work of operators and ensuring product quality.

Valve pile tip structure device of cast-in-place X-shaped concrete pile and using method thereof

The invention relates to a valve pile tip structure device of a cast-in-place X-shaped concrete pile and a using method thereof. In the valve pile tip structure device, an X-shaped pile die is fixedly connected with a connecting section, the lower end of the connecting section is fixedly connected with a transition section, the lower part of the transition section is rotatablely connected with the upper part of a strengthening rib through a connecting hinge, and the strengthening rib is fixedly connected with a valve; and when the X-shaped pile die is dropped down, the valve pile tip is aligned with a pile position, and a curved surface triangular steel sheet is closed and inserted in a soil body, the X-shaped pile die is vibrated to reach a designed depth so that concrete enters an inner cavity of the valve, and the X-shaped pile die is pulled up to automatically open the curved surface triangular steel sheet so as to form the cast-in-place X-shaped concrete pile. The valve pile tip structure device overcomes the defects that a precast pile shoe is precast in a factory, has long consumed time, large volume and inconvenient transportation, moves and deflects downwards and even breaks away from the pile die, cannot be used repeatedly, has high manufacturing cost, and the like. The valve pile tip structure device avoids repeated physical work, does not need to be precast in the factory, shortens the construction period, and reduces the cost.

Flash memory array management method and device

The invention is applicable to the technical field of computer data storage and provides a flash memory array management method and device. The flash memory array management method comprises the steps of dividing a flash memory array into n physical working groups, wherein the same pages of all flash memories in the same physical working group are combined to form a physical combined page, and the same blocks of all flash memories in the same physical working group are combined to form a physical combined block; dividing a logic space into a plurality of logic pages according to the size of the physical combined page, dividing the multiple obtained logic pages into n logic working groups corresponding to the physical working groups, performing re-addressing according to logic addresses of the logic pages of the same logic working group to obtain logic combined pages; managing the logic combined pages in the logic working groups and the physical combined page in the corresponding physical working groups in a dynamic mapping mode so as to achieve reading and writing of the flash memory array. By means of the flash memory array management method and device, the storage space occupied by a mapping table is decreased, and write-in and amplification caused by block mapping are decreased.
