Abstract
The utility model relates to a petroleum drilling device, in particular to a kelly bar plug valve. The kelly bar plug valve comprises a valve body. A fixing part is arranged at the upper portion of the inner wall of the valve body. An adjusting nut is formed in the upper end of the fixing part. The lower end of the fixing part is connected with an upper valve seat. The lower end of the upper valve seat is connected with a valve ball. The side wall of the valve ball is connected with an operating bar which is arranged on the side wall of the valve body. The lower end of the valve ball is connected with a lower valve seat which is arranged on the inner wall of the valve body. The kelly bar plug valve is compact in structure, low in cost, convenient to operate, low in labor intensity, and capable of effectively preventing the phenomenon of incontrollable wellhead inner injection and improving the safety of drilling operation.
Description
Technical field
The utility model relates to a kind of oil drilling and extracting equipment, is specifically related to a kind of kelly cock.
Background technology
In drillng operation, in case blowout out of control takes place, will make petroleum resources be subjected to heavy damage, easily lead to fire, cause casualties, consequence such as equipment breaking-up, at present, the oil field is extensive use of preventer, choke manifold and control system and prevents that blowout from taking place, complicated operation, and labour intensity is big.
Summary of the invention
The purpose of this utility model is to provide a kind of compact conformation, and is easy to operate, is installed in the kelly cock that can be easy to open and close of kelly bar bottom.
The technical solution of the utility model is:
Kelly cock, comprise valve body, valve interior wall top arranges fixed part, the fixed part upper end has adjusting nut, and the fixed part lower end connects upper valve base, and the upper valve base lower end connects valve ball, valve ball sidewall attended operation bar, action bars is arranged on the body wall, and the valve ball lower end connects lower valve base, and the lower valve base seat is on valve interior wall.
Concrete, valve body and junction, upper valve base lower end arrange the distinguish baffle ring.
Concrete, between valve body and the upper valve base sealing ring is set.
Concrete, boss is set on the valve interior wall, spring is set on the boss, the lower valve base seat is on spring.
The utility model work is installed on kelly bar bottom or the oil pipe time, in case when spraying in well head takes place in drilling process, available handle, put into action bars, the valve ball clockwise direction is turn 90 degrees, can control blowout, when getting rid of blowout and continuing to spud in, valve ball counterclockwise turn 90 degrees get final product.
The utility model compact conformation, cost is low, and is easy to operate, and labour intensity is little, can effectively prevent spray out-of-control phenomenon in the well head, the safety that has improved drillng operation.
