Description

VALVE DEVICE FOR DRILLING PIPES.

The utility model relates to the oil and gas industry and is used when drilling wells, for example, with turbine engines, and serves to freely pass the working fluid to the turbine in one direction and to block the pipe space of the column from possible oil and gas manifestations through it when opening the productive horizon.

Known valve device containing a check valve with a locking element and a control device, see French patent Ke 2588915 according to CL.E21B34 / 00, publ. 1987.

The check valve control device does not provide the necessary reliability during operation.

Known valve device for a string of pumping pipes containing a valve in the form of a seat and a ball locking element, and a control device for the locking element in the form of a support nut located in the valve body above the seat, see patent of the Russian Federation No. 2049225 for cl. ЕВВ 34/06, publ. 1995 year

In this device, the control of the locking element has a complex structure, which reduces operational reliability.

This technical solution is taken as a prototype of this utility model.

However, it has a disadvantage.

The prototype valve does not have an attachment for fixing the shutter in an open, intermediate position before the valve is lowered into the well, which worsens the operating conditions.

The present utility model is based on the solution of a problem that allows for reliable fixation of the valve shutter opening before lowering it into the well and to improve operational conditions.

According to a utility model, this problem is solved due to the fact that the valve device comprises a non-return valve, a housing with a valve in the form of a ball with a seat, a guide, a pusher, a dog, the device is equipped with a locking device in the form of a handle with a protrusion, and in the valve guide a pusher and an auxiliary pusher are installed, the pusher is meshed with the dog, pivotally connected to the guide and the auxiliary pusher, while a ledge is made in the auxiliary pusher that responds to the protrusion ki devices.

The applicant has not identified sources containing information on technical solutions identical to this utility model, which allows us to conclude that it meets the criterion of “novelty.

The essence of the utility model is illustrated by drawings, which depict:

in FIG. 2 - node a in FIG. L,

in FIG. 3 - check valve - positional position / section /,

in FIG. 4 - fixing device / general view /.

The valve device consists of:

Check valve 1,

fixing device 2,

Check valve 1 contains:

case 3,

shutter 4 (in case 3),

ball 5 (shutter 4),

saddle 6 (shutter 4),

guide 7 (in corne 3),

a pusher 8 (in the guide 7),

auxiliary pusher 9 (in the guide 7),

ledge 10 (pusher 9),

Doggie 11.

The locking device 2 contains:

handle 12,

ledge 13 / handles 12 /.

Klsh1an 1 of the device consists of a housing 3, in which the shutter 4 is placed in the form of a ball 5 with a saddle 6, a guide 7, a pusher 8, an auxiliary pusher 9 and a dog 11. The pushers 8 and 9 are installed in the guide 7. The pusher 8 is engaged with the dog 11, pivotally connected to the guide 7 and the auxiliary pusher 9. Ya to the auxiliary pusher 9 is made yciyn 10. The locking device 2 of the valve device is made

in the form of a handle 12 with a ledge 13.

The ledge 10 of the pusher 8 of the valve 1 interacts with the protrusion 13 of the handle 12 of the locking device 2.

Pa6oia valve device is as follows.

The valve 1 of the device is installed in the drill pipe string (in addition to the main valve under the drill pipe), as a blow-out valve, when opening the productive potter & Fed by installing valve 1, it is opened, for which purpose clamping device 2 is pressed on tolkazel 8 and rotated into Tspyr wasp until the fixture 2 with its protrusion 13 does not fall into the ledge 10 of the auxiliary pusher 9. After that, both pushers 8 and 9 are pressed by the fixture 2 all the way into the guide 7. Then, the locking fixture 2 is turned into circle its axis until the protrusion 13 does not come out of the ledge 10 of the auxiliary pusher 9. In this case, the valve 1 takes an open position. Then it is fixed into the drill pipe string and lowered into the well. As you descend, the pipe string is filled with borehole fluid cherk open valve: pan 1. After turning on the supply of the working fluid (to rotate the turbo engine), the ball 5 of the shutter 4 is squeezed out, while pushing. 8 Closes the ball 5, and the pusher 9 moves in parallel with the fluid and rotates the dog 11, which disengages from the pusher 8. When the supply of the working fluid to the pipe string stops, the ball 5 is pressed against the seat 6 and overlaps the capacity of the fluid in the opposite direction. When this pusher 8 rises with the ball

4

5, but not engaged with the dog 11, which is in the allotted state. The return of the dog 11 to its original position is possible only with the help of the locking device 2.

The proposed valve device can be manufactured using the M1) method, which confirms the tests of the experimental batch, and this, in the applicant's opinion, stipulates that it should be installed in 4 industrial applications.
