Embodiment
Particular content of the present utility model is described in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Fig. 3, four-way adjusting control valve, comprise: four-way valve body 1, be arranged on the blank flange 2 of four-way valve body 1 lower end and be arranged on the gland 3 of four-way valve body 1 upper end, crosspassage 4 and vertical passage 5 is staggeredly equipped with at the middle part of described four-way valve body 1, be provided with in described four-way valve body 1 and control spool 6, passage 7 is provided with in described control spool 6, described control spool 6 is arranged on one end of adjusting screw 8, the other end of described adjusting screw 8 stretches out four-way valve body 1 and is connected with handwheel 9, bearing support 10 is provided with between described adjusting screw 8 and four-way valve body 1, interior thrust ball bearing 11 and lock nut 12 is provided with between the upper end and adjusting screw 8 of described bearing support 10, lock sheet 13 is had in the upper end arranged outside of described bearing support 10, the upper end of described bearing support 10 is fixed on described gland 3 by lock sheet 13 and limited bolt 14, tapering roller bearing 15 and extrapolability ball bearing 16 and seal ring 17 is provided with between described bearing support 10 and four-way valve body 1.
Working principle: four-way adjusting control valve is mainly arranged on wellhead tree tree or manifold and utilizes its four-way pipeline to connect, the function that regulable control pipeline leads directly to solves the problem that four-way self can not regulate emergency flight control, provides temporal guarantee to the repairing of the arbitrary pipeline connect under four-way.
Graduating valve can regulable control one side leads directly to pipeline is at any time that the rapid rush-repair operation of the opposing party's well head pipeline obtains should be free to adopt four-way control to adjust, and control well mouth pressure effectively in time, ensures wellhead equipment and personal security.During normal work, four-way is in normally open as shown in Figure 1, does not need four-way adjusting control valve to carry out regulable control, is undertaken controlling the pressure in balanced well mouth pipeline by four plate valves of the left and right sides.In emergency circumstances can lead directly to the direct regulable control pipeline of four-way adjusting control valve when running into, blocked simultaneously four-way all the other two lead to, namely by left-handed handwheel 9 adjusting screw 8 turned left together, adjusting screw 8 is with brake control valve core 6 to rise together again, because adjusting screw 8 is connected with control spool 6 screw thread, connecting thread is left-handed thread, when control spool 6 rise to be close to mutually with bearing support 10 until revolve motionless till, now in four-way control valve, crosspassage 4 is connected by passage 7, the unimpeded of crosspassage 4 can only be controlled, namely left and right directions is as shown in Figure 2 unimpeded.Because control spool 6 one weeks is all overall pressure injection round rubber fuse, there is good sealability, and perpendicular vertical passage 5 is closed.The bottom of four-way control valve is that blank flange 2 reaches sealing effect by bolt compression seal plug 16.Top forms by positions such as sealing plug 16 inside and outside bearing support 10 and gland 3 Sealings the safety that control valve is guaranteed in sealing.
If when vertical passage 5 is opened in adjustment, then first must take off limited bolt 14 and remove locking to bearing support 10, continue left-handed handwheel 9, control spool 6 under the drive due to handwheel 9 and risen to be close to mutually with bearing support 10 and revolve motionless for upper, at this moment bearing support 10 is with to control spool 6 one-tenth as a whole; If continue to revolve, overall transfer, owing to bearing support 10 being equipped with extrapolability ball bearing 16 and tapering roller bearing 15 is convenient to integral-rotation.
In time being rotated in place, be again locked on gland 3 by limited bolt 14 and lock sheet 13 by bearing support 10, now vertical passage 5 is unimpeded, and the crosspassage 4 laterally on (left and right) direction is closed and reached regulating effect as shown in Figure 3.
Dextrorotation handwheel 9 is only needed when four-way is all opened until control spool 6 revolves motionless bottom dropping to, as shown in Figure 1 if recover.
Above-mentioned four-way adjusting control valve; except keeping the function of original four-way, also there is the straight-through function (namely single pipeline is unimpeded) of regulable control pipeline; be combined into together by the function such as four-way, regulable control; not only safety and environmental protection also reduces labor intensity and substantially increases working efficiency, solves the key issue that four-way self can not regulate emergency flight control.
