Connecting device between side gate and shell of ram blowout preventer

Abstract

The invention discloses a connecting device between a side gate and a shell of a ram blowout preventer, which relates to the technical field of the connection between the side gate and the shell of the ram blowout preventer in oil well control equipment and comprises a clamp board mechanism and a connecting part, wherein one end connected with a clamp board is a fastening end, and the other end is a connecting end; the fastening end has a convex plate with an arc-shaped inclined plane; and the connecting end is provided with a bolt pin convex plate. The connecting device resolves the problems of long disassembling operation time and large labor intensity when overhauling or replacing parts. The invention adopts a fast buckle mode and designs a connecting device capable of disconnecting and connecting the side gate from / with the shell of the ram blowout preventer fast, and the connecting device has fast disconnecting and connecting characteristics.

Problems solved by technology

[0002] In the process of oil and gas exploration and development, for the purpose of safe drilling, a ram blowout preventer must be installed at the wellhead. The ram blowout preventer currently used has a blowout preventer housing and side doors that are the main pressure-bearing components. , and the opening of the side door of the ram BOP generally has two structural forms: side opening and direct opening, and the connection between the side door of the ram BOP and the BOP shell is generally completely bolted; during use, Due to pressure and wear and other reasons, it is often necessary to overhaul the ram BOP and replace the ram and other parts installed in the BOP shell. In order to open the side door, under the current bolt connection method, the connecting bolts must be removed. Then after maintenance or replacement of parts, close the side door, install and tighten the connecting bolts, because the side door of the ram BOP and the BOP shell need to be sealed and pressure-bearing, the bolt connection is good or bad, It will directly affect the sealing effect between the side door of the ram BOP and the BOP shell; however, due to the limited position of the screw holes on the side door of the ram BOP, the connecting bolts are not easy to remove, and it is not easy to tighten after removal; Due to the heavy connection method, it takes a long time to complete the installation or disassembly operation, and the labor intensity is high. A little carelessness will also cause the connection to be loose. If the connection is not tight, the seal will not be good, and it will also cause damage to the pressure bearing capacity. , making drilling unsafe
