III. Structure Characteristics
The BOP consists of body, ram assembly, equalizing valve, end cap, stem, handle, O ring, etc.
IV. Operation Procedure
1. Installation
1.1 Close the wellhead valve. Clean the seal bore of wellhead adapter. Then install it.
1.2 Install the lubricator or other device in to the top of BOP.
2. Open
2.1 Open the valve plug of equalizing valve with allen wrench.
2.2 After the pressure is equalized, rotate the handle anticlockwise. Then ram will be opened.
2.3 Close the equalizing valve.
3. Close.
Rotate the handle clockwise. Then ram will be closed.
IV. Maintenance
1. Disassemble BOP after operation and clean the parts. Check the sealing-face or seal parts carefully.
Replace the worn parts in time.
2. After each disassembly, it is a must to conduct the seal test.
3. Strength test must be conducted on time.
