The assembly process of the invention: installing each O-shaped sealing ring on a corresponding part; clamping the connecting short section 9 by using a vice, installing a spring retainer ring 13 and a spring 10 into a spring core sleeve 11, and then connecting the upper end of the spring core sleeve 11 with the lower end of the connecting short section 9; and connecting the ball valve assembly, the control arm 8 and the connecting short joint 9. The vice clamps the outer cylinder 5, connects the control sleeve 7, the operating pin 17 and the ball valve assembly, and the whole body passes through the inner part of the outer cylinder 5; connecting a J-shaped groove sleeve 12 to the lower end of the outer cylinder 5, installing a lug mandrel 15 into the J-shaped groove sleeve 12, connecting a J-shaped groove protective cap 14 to the lower end of the J-shaped groove sleeve 12, and connecting a lower joint 16 to the lower end of the lug mandrel 15; and (3) connecting the buffer sealing ring 2, the upper ball seat 4, the retainer ring 3 and the upper joint 1, then connecting the whole upper joint 1 with the outer cylinder 5, and finishing the assembling procedure.
The invention has the following steps: the pressure test valve is arranged on a working pipe column, a ball valve assembly is in a floating state in the structure, the radial direction is limited by the inner diameter of an outer cylinder 5 through a control arm 8 and a control sleeve 7, and the axial movement is limited by an operating pin 17. When the pressure test valve is used for downhole operation, the pressure test valve is generally in a locking opening state, and even if the ball valve assembly is in a closing state, the pressure difference acts on the ball valve body 6 to enable the ball valve assembly to float upwards and slightly open the ball valve body 6. When the ball valve body 6 is in the open position, the upper ball seat 4 prevents impurities such as cement from entering the rear of the ball valve assembly.
When the ball valve is used, the upper connector 1 and the J-shaped groove sleeve 12 are driven to axially move up and down through the up-and-down movement of the outer cylinder 5, the upper connector 1 and the J-shaped groove sleeve 12 push the control sleeve 7 to move through the end shoulder, and the control sleeve 7 finally drives the operating pin 17, so that the ball valve body 6 is rotated. The outer cylinder 5 and the components fixedly connected with the outer cylinder start to move downwards, the ball valve assembly moves downwards, when the outer cylinder 5 and other components move downwards to a certain extent, the spring 10 and the spring core sleeve 11 at the lower part of the ball valve assembly contact the lug mandrel 15, the elastic claw structure 1101 of the spring core sleeve 11 is clamped in the elastic claw clamping groove 1502 of the lug mandrel 15, and the ball valve assembly stops moving. As the outer barrel 5 continues to move downwards, the ball valve body 6 will be rotated open by the operating pin 17, when the ball valve body 6 is fully open, the lower ball seat 24 will encounter the operating pin 17, any additional downward movement of the outer barrel 5 will compress the spring 10, and finally the ball valve assembly will be retained within the short slot of the J-slot 1201 of the J-slot sleeve 12 by the lugs 1501 on the lug mandrel 15. When a left-hand torque is applied, the outer barrel 5 and other components are rotated until the lug 1501 is clamped in the long groove of the J-shaped groove 1201, the outer barrel 5 is lifted upwards, and the ball valve assembly is opened. Wherein the design of the elastic claw structure 1101 on the spring core 11 can ensure the accurate and reliable closing of the ball valve assembly, and finally the movement of the outer cylinder 5 and other components is limited by the blocking of the shaft shoulder on the lug mandrel 15 through the J-shaped groove protective cap 14.
The pressure test valve is an automatic J-shaped groove control operation, and an operator must apply enough weight to the pressure test valve to enable the lug 1501 on the lug mandrel 15 to be positioned at the upper part of the J-shaped groove 1201, so that the J-shaped groove 1201 can be positioned at a locking opening position. The self-locating feature of the J-slot 1201 allows the lug 1501 on the lug mandrel 15 to remain in the locked open position unless left hand torque is applied to the pressure valve when it is lifted, and the closed position can be achieved by only slightly turning the left hand rotary column and lifting the pressure valve.
The pressure test valve is a full-bore tool, carries out multiple pressure tests on an oil pipe before cement squeezing or other operations according to requirements, can be matched with any Haributton packer for use, and can also be independently used if a friction block mechanism is used; when used with RTTS packers, the present pressure test valve is typically installed below the circulation valve. When operating in the well, the differential pressure acting on the ball valve body 6 will cause the ball valve assembly to float upward and slightly open the ball, regardless of the position of the lugs 1501 on the lug mandrel 15 in the J-slots 1201, even if the ball valve assembly is closed by the operating pin 17. Once the pressure test valve is in the open position, the spring 10 at the lower part of the ball valve assembly can keep the hole on the ball valve body 6 and the hole of the oil pipe in the correct position, although the J-shaped groove 1201 is in the locked open position with some clearance, no matter how the oil pipe moves up and down, a steel wire operation tool and the like can be used through the pressure test valve.
