Abstract
The utility model relates to a by-pass valve which is composed of a sieve tube, an upper connector, a valve cover, a valve ball, a spring, a valve body and a lower connector. The lower part of the sieve tube is connected with the upper part of the upper connector; the lower part of the upper connector is connected with big threads at the upper part of the valve body; the lower part of the valve body is connected with the upper connector; the lower part of the valve cover is connected with small threads at the upper part of the valve body; the valve ball and the spring are mounted in the valve cover; a side vertical channel is arranged on the valve body; a radial channel is arranged on the valve body; and the side vertical channel is not communicated with the radial channel. A communicating hole is formed on the sieve tube. The radial channel composed of a plurality of circular holes is formed on the valve body. Well fluid enters the valve from the radial channel; liquid in the valve can not flow out form the radial channel and can seal pipe columns; sands and miscellaneous articles are blocked by the sieve pipe, settle down into the lower part from the side vertical channel, and can not fall on the valve ball; the inflowing channel is smooth always; and pressure in the valve can also be transferred to the lower part, thereby satisfying the special process requirements.
Description
One, technical field
The utility model belongs to the oil field downhole tool, is a kind of flow divider.
Two, background technology
The present airtight down-hole string of down-hole ball-and-seat energy is realized operations such as pressure testing, but can not be made ball-and-seat UNICOM up and down, can not shunt, to satisfy the special process requirement.Present down-hole ball-and-seat also exists by foreign material and buries, and causes the blocked problem of runner.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of flow divider, reaches airtight tubing string, realizes the purpose of shunting, can also guarantee not buried by foreign material, makes runner unimpeded.
The purpose of this utility model is achieved in that by screen casing, top connection, valve bonnet, valve ball, spring, valve body, lower contact to be formed, the screen casing bottom connects with top connection top, the top connection bottom connects with valve body top major thread, valve body lower portion connects with top connection, the valve bonnet bottom connects with valve body top minor thread, and valve ball, spring are installed in the valve bonnet, has side to erect passage on the valve body, the radial passage is arranged on the valve body, and perpendicular passage of side and radial passage be UNICOM not.
Linked hole is arranged on the screen casing.
Form by a plurality of circular holes by the radial passage on the valve body.
The beneficial effects of the utility model are: newly-designed flow divider can reach purpose of design, well liquid enters in the valve from the radial passage, liquid can not flow out from the radial passage in the valve, the airtight tubing string of energy, the sand foreign material are blocked by screen casing, sink to the bottom through the perpendicular passage of side, can not drop on the valve ball, the influent stream passage is unimpeded all the time, and the pressure in the valve also can be delivered to the bottom, can satisfy the special process requirement.
Four, description of drawings
Accompanying drawing is the utility model embodiment assembling drawing.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in the figure, form by screen casing 1, top connection 2, valve bonnet 3, valve ball 4, spring 5, valve body 6, lower contact 9, screen casing 1 bottom connects with top connection 2 tops, top connection 2 bottoms connect with valve body 6 top major threads, and valve body 6 bottoms connect with top connection 2, and valve bonnet 3 bottoms connect with valve body 6 top minor threads, valve ball 4, spring 5 are installed in the valve bonnet 3, have side to erect passage 8 on the valve body 6, radial passage 7 is arranged on the valve body 6, perpendicular passage 8 of side and radial passage 7 be UNICOM not.
On the screen casing 1 linked hole is arranged.
Form by a plurality of circular holes by radial passage 7 on the valve body 6.
