Oilfield Annular BOP / Blowout Preventer for Oil Well Control
Product Introduction
Annular blowout preventer is manipulated by hydraulic control system. When it is shut off, high pressure oil flows into piston underside closed cavity through the oil port in central shell, to push piston upwards, and the conical surface of piston squeezes rubber core. Due to the restrictions of head cover, rubber core can't go upwards but is pushed towards the center of wellhead until it enclasps drilling tool or enclose wellhead totally to shut the well. When well needs to be opened, manipulate the reversing valve of hydraulic control system, so that high pressure oil should flow into the open cavity on top of piston through the oil mouth on shell, to push piston downwards and decompress closed cavity, in which case, the extrusion force on the conical surface of rubber core is removed, and the rubber core is reset gradually with the action of its own elastic force to open wellhead.

Main Characterstics of Our Annular BOP:
1) According to the number of ram installed in each set, ram BOP can be divided into: Single ram, double ram and three ram BOP, which are respectively installed with one ram, two rams or three rams.
2) According to the ram opening and closing method, ram BOP can be divided into manual locking and hydraulic locking.
3) According to the different opening and closing method of bonnet, ram BOP can be divided into two forms: Rotating bonnet ram BOP and linear bonnet ram BOP. For the rotating bonnet ram BOP, when opening or closing bonnet, the bonnet rotates on the hinge sear fastened on the body, the ram cam cavity shape of such BOP is rectangle.
4) For the linear bonnet ram BOP, when opening or closing bonnet, the bonnet makes linear motion along the two bonnet opening and closing plunger rods fastened on the body, the ram cavity shape of such BOP is elliptic.
