Abstract

The utility model discloses an equilibrium ball valve of a plug valve, comprising a valve body with a valve cavity and a ball valve installed in the valve cavity, wherein the ball valve is provided with a switch slot matched with a switch. The utility model is characterized in that the switch slot is provided with a through hole communicated with the inner passage of the ball valve. The equilibrium ball valve of the plug valve can always keep the same pressure between the passage of the ball valve and the outer surface of the ball valve by the through hole communicated with the inner passage of the ball valve under the complex conditions in the underground to play pressure of the equilibrium ball valve, ensuring the flexible opening and closing of the ball valve, and increasing the working life of the ball valve.

Description

旋塞阀平衡球阀 Balance ball cock

技术领域 FIELD

[0001] 本实用新型涉及石油、天然气钻井作业用的内防喷工具,特别是一种旋塞阀平衡球阀。 [0001] The present invention relates to oil and gas drilling operations within the BOP tools used, in particular a stopcock balance ball.

背景技术 Background technique

[0002] 旋塞阀作为石油、天然气钻井作业必备的钻具内防喷工具之一,在正常钻井作业时由于其安装于钻柱的上端。 [0002] One of the stopcock as oil and natural gas drilling operations necessary BOP drill tool, when working in a normal drilling due mounted to the upper end of the drill string. 目前旋塞阀结构可以参考中国实用新型专利200420005536. 4 中所描述,旋塞阀的球阀均为一般球阀,该球阀在使用的过程中,由于球阀的中间通道与其外球面环形空间不能勾通,当带压钻进液从中间通道流过时,造成球阀内外压力的不平衡, 从而引起球阀的震动和串位。 Currently stopcock structure may refer to the Chinese utility model patent 200420005536.4 described, the ball plug valves are typically ball valve during use, since the ball valve spherical annular intermediate space with the outer passage can not collude, when pressurized drilling fluid flows from the intermediate passage, and external pressure caused by the imbalance of the ball, causing the ball valve and the bit string vibration. 影响了球阀的启闭性能,严重时使球阀受到卡滞而不能关闭, 导致井场安全事故的发生。 Affect the performance of the opening and closing of the ball, the ball being serious catching and can not be closed, leading to the well site accidents.
