III.Structural features:
BOP is mainly composed of shell, ram assembly, balance valve, manual control mechanism and lower joint.The upper part of the casing is connected with the blowout preventer or the drop preventer, and the lower joint is connected with the wellhead joint or the Christmas tree. The gate assembly is composed of gate guard, gate body, gate inner seal for steel wire, gate outer seal, guide key, etc. The gate body is controlled by the manual control mechanism to move closer to the center, and the steel wire is sealed by the inner seal of the gate to seal the steel wire clamp.
When the blowout preventer is closed and there is no pressure in the blowout preventer, it is very difficult to open the blowout preventer directly and it is easy to damage the inner seal. Therefore, it is necessary to open the balance valve first, and then open the blowout preventer after the upper and lower pressures of the blowout preventer are balanced. Finally close the balance valve.

IV.Precautions:
1. Check the inner and outer seals and O-rings of the gate in time, and replace them in time;
2. After each maintenance, a performance test (gate seal test) should be done;
3. Regular strength tests are carried out.
