Controllable pressure release anti-theft blowout preventer for oil and gas wellhead
The invention relates to the technical field of oil field wellhead equipment, in particular to a controllable pressure release anti-theft blowout preventer for an oil and gas wellhead. And the three functions of controlling and safely discharging the pressure in the well, preventing oil stealing and preventing damage are integrated. The sealing device comprises a sealing main body connected with a wellhead casing coupling, a controllable pressure release valve is arranged in the sealing main body, the sealing main body is connected with a coded lock and a key, and the coded lock is connected with an anti-theft protection cover sleeved on the sealing main body. The lower part of the sealing main body is a hollow pipe buckle, the middle part is provided with a radial through hole, and the upper end part is provided with a lock plate clamping groove with an upper opening; and one side of the radial through hole of the sealing main body is provided with a controllable pressure release valve which is transversely opened, and the other side of the radial through hole of the sealing main body is provided with a connecting port which is connected with a ground pressure release pipeline. The coded lock comprises a lock cylinder, a connecting body and a lock body which are sequentially connected, the lock cylinder is connected with a drive plate mechanism, and the lower end of the lock body is connected with a driving lever and a lock plate mechanism. The device has the characteristics of compact structure, simplicity in operation and higher applicability.
本发明涉及油田井口设备技术领域，即油气井口可控放压防盗封井器。集可控安全排放井内压力、防止盗油、防破坏三大功能于一体。它包括与井口套管接箍连接的密封主体，密封主体内有可控放压阀,密封主体连接密码锁和钥匙,密码锁连接套在密封主体上的防盗保护罩。所述的密封主体下部是中空的管扣，中部有径向通孔，上端部带有上端开口的锁板卡槽；径向通孔与密封主体径向通孔连通，密封主体径向通孔一侧装有横向开启的可控放压阀，另一侧是连接地面放压管线的连接口。所述的密码锁包括顺次连接的锁芯、连接体、锁体，锁芯连接拨盘机构，锁体下端连接拨杆、锁板机构。具有结构紧凑，操作简单，适用性更强的特点。
