Annular Blowout Preventer Structure Characteristics
1- The connection between top cap and housing, top and bottom ends adopt flanges
2- Semisphere rubber core has many advantages, such as not easy folding back, bigvolume of rubber storage. Under the well pressure, the piston pushes the rubber core upward to form a funnel shape. The funnel effect of rubber
core increases its sealing performance and life span.
3- Characteristics of the sealing structure include:
(1) The BOP has three important sealing positions: piston external surface seal, piston internal surface seal and mud blocking ring seal.
(2) Radial direction cross section of the piston comes of the shape "Z", which makes the piston have short stroke length, low height and big diameter.
(3) There are two wear-rings stick to the external surface of the piston and a wear-ring stick to the internal surface of the housing. The structure prevents metal to metal contact and protects piston and housing.
