Abstract
The invention provides an anti-blowout control valve. A lower locating seat is arranged at the lower part of the inner cavity of a valve body; a ball valve is arranged on the lower locating seat; an upper locating seat is arranged above the ball valve; the lower end of the upper locating seat is located on an inner shoulder of the valve body; a pressing cap is connected with the upper part of the valve body and used for pressing the upper locating seat; a locating seat sealing ring is arranged between the upper locating seat and the valve body; an anti-blowout sealing ring is arranged between the upper locating seat and the ball valve; a faucet is arranged on the side face of the valve body; the front end of the faucet is inserted into the ball valve; a faucet sealing ring is arranged between the faucet and the valve body; an inner through hole is formed on the ball valve; and an inner shoulder is arranged at the lower part of the valve body. If blowout exists, a suspension connector is arranged at the upper part of an oil pumping rod; the suspension connector is arranged on the inner shoulder at the lower part of the valve body, and a rod piece above the suspension connector is taken away; the faucet is rotated to make the ball valve rotate 90 degrees, so the inner through hole 10 on the ball valve is closed; therefore, the anti-blowout control valve prevents the blowout, avoids personnel injury accidents and crude oil loss and environmental pollution, and brings outstanding economic benefit and social benefit.
Description
Technical field:
The rig tool that the present invention uses when being the oil field pumping well operation is a kind of blowout prevention control valve.
Background technology:
When playing lower sucker rod, sucker rod is being carried by working rig, the sucker rod upper end is exposed on the wellhead assembly, and the sucker rod lower end is under wellhead assembly, if blowout takes place, sucker rod can not trip out fast, close wellhead assembly and can't seal oil well, well inner high voltage liquid stream will eject, and cause personnel's injury accident on the one hand, cause crude oil loss and environment pollution on the other hand, produce heavy economic losses.
Summary of the invention:
Originally the objective of the invention is to design a kind of blowout prevention control valve, when in playing the lower sucker rod process, blowout taking place, can close well head, prevent blowout.
This present invention's purpose is achieved in that and comprises pressure cap, last positioning seat, the positioning seat sealing ring, the cock sealing ring, cock, ball valve, following positioning seat, valve body, the blowout prevention joint ring, following positioning seat is installed in the body cavity bottom, ball valve seat is on following positioning seat, install positioning seat on the ball valve, last positioning seat lower end is positioned on the interior shoulder of valve body, pressure cap is connected with valve body top, pressure cap is pushed down positioning seat, last positioning seat and valve body) between installing and locating seat sealing ring, the blowout prevention joint ring is installed between last positioning seat and the ball valve, cock is installed in side of valve body, the cock front end inserts in the ball valve, the cock sealing ring is installed between cock and the valve body, inner via hole is arranged on the ball valve, valve body lower portion has interior shoulder.
The written or printed documents beneficial effect of the invention is: when having blowout to show, a suspension joint will be installed on sucker rod top, with the suspension joint seat on the interior shoulder of valve body lower portion, take the rod member on the suspension joint away, the rotation cock makes the ball valve half-twist, and the inner via hole 10 on the ball valve is closed, can prevent blowout, avoid taking place personnel's injury accident, also can avoid crude oil loss and environment pollution, have remarkable economic efficiency and social benefit.
Description of drawings:
Fig. 1 is the assembling drawing of this embodiment of the invention.
The specific embodiment:
Below in conjunction with Fig. 1 these embodiments of the invention are described.
As seen from the figure, this the present invention comprises pressure cap 1, last positioning seat 2, positioning seat sealing ring 3, cock sealing ring 4, cock 5, ball valve 6, following positioning seat 7, valve body 8, blowout prevention joint ring 9, following positioning seat 7 is installed in valve body 8 inner chamber bottoms, 6 of ball valves are on positioning seat 7 down, install positioning seat 2 on the ball valve 6, last positioning seat 2 lower ends are positioned on the interior shoulder of valve body 8, pressure cap 1 is connected with valve body 8 tops, pressure cap 1 is pushed down positioning seat 2, installing and locating seat sealing ring 3 between last positioning seat 2 and the valve body 8, blowout prevention joint ring 9 is installed between last positioning seat 2 and the ball valve 6, sealing well head when ball valve 6 is closed, cock 5 is installed in the side of valve body 8, cock 5 front ends insert 6 li of ball valves, cock sealing ring 4 is installed between cock 5 and the valve body 8, inner via hole 10 is arranged on the ball valve 6, interior shoulder 11 is arranged at valve body 8 bottoms.Valve body 8 bottoms are clamp connection 12, are convenient to be connected with other accessory of well head.
When playing lower sucker rod, ball valve 6 is in state as shown in the figure, the oil well pump piston, rod collar all can be by the inner via hole 10 on the ball valve 6, can play lower sucker rod smoothly, when blowout shows, to a suspension joint be installed on the sucker rod top that also is not lowered to or proposes, suspension joint, external diameter greater than the aperture of aperture, valve body 8 bottom less than the inner via hole on the ball valve 6 (10), on the interior shoulder 11 of valve body 8 bottoms, the sucker rod under the suspension joint is suspended on the valve body 8 with the suspension joint seat, take the rod member on the suspension joint away, suspension joint is under the ball valve 6, does not hinder ball valve 6 rotations, rotates cock 5 then and makes ball valve 6 half-twists, inner via hole 10 on the ball valve 6 is closed, can prevent blowout, treat after pressure is put in kill-job that blowout is eliminated just can continue operation.
