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 pumping in oil fields well operations is a kind of Anti-blowout control valve.
Background technology:
During actuating oil-pumping unit, sucker rod is being carried by working rig, the sucker rod upper end is exposed on wellhead assembly, and the sucker rod lower end is under wellhead assembly, if blowout occurs, 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 on the one hand personnel's injury accident, cause on the other hand crude oil loss and environment pollution, produce heavy economic losses.
Summary of the invention:
Originally the objective of the invention is to design a kind of Anti-blowout control valve, when in the actuating oil-pumping unit process, blowout occuring, can close well head, prevent blowout.
this purpose of the present invention is achieved in that and comprises pressure cap, upper positioning seat, the positioning seat sealing ring, the cock sealing ring, cock, ball valve, lower positioning seat, valve body, the blowout prevention joint ring, lower positioning seat is arranged on the body cavity bottom, ball valve seat is on lower positioning seat, install positioning seat on ball valve, upper 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, upper positioning seat and valve body) between the positioning seat sealing ring is installed, the blowout prevention joint ring is installed between upper positioning seat and ball valve, cock is arranged on the side of valve body, the cock front end inserts in ball valve, the cock sealing ring is installed between cock and valve body, inner via hole is arranged on 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, to a suspension joint 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 suspension joint away, the rotation cock makes the ball valve half-twist, and the inner via hole 10 on ball valve is closed, can prevent blowout, avoid occuring personnel's injury accident, also can avoid crude oil loss and environment pollution, have significant economic benefit and social benefit.
Description of drawings:
Fig. 1 is the assembling drawing of this embodiment of the present 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, upper positioning seat 2, positioning seat sealing ring 3, cock sealing ring 4, cock 5, ball valve 6, lower positioning seat 7, valve body 8, blowout prevention joint ring 9, lower positioning seat 7 is arranged on valve body 8 inner chamber bottoms, 6 of ball valves are on lower positioning seat 7, install positioning seat 2 on ball valve 6, upper 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, positioning seat sealing ring 3 is installed between upper positioning seat 2 and valve body 8, blowout prevention joint ring 9 is installed between upper positioning seat 2 and ball valve 6, sealing wellhead when ball valve 6 is closed, cock 5 is arranged on 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 valve body 8, inner via hole 10 is arranged on 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.
during actuating oil-pumping unit, ball valve 6 is in state as shown in the figure, oil pump piston, rod collar all can be by the inner via hole 10 on ball valve 6, actuating oil-pumping unit smoothly, when having blowout to show, a suspension joint of sucker rod top installation that will also not be lowered to or propose, suspension joint, external diameter greater than the aperture less than the inner via hole on ball valve 6 (10), valve body 8 apertures, bottom, with the suspension joint seat on the interior shoulder 11 of valve body 8 bottoms, sucker rod under suspension joint is suspended on valve body 8, take the rod member on suspension joint away, suspension joint is under ball valve 6, do not hinder ball valve 6 rotations, then rotate cock 5 and make ball valve 6 half-twists, inner via hole 10 on ball valve 6 is closed, can prevent blowout, after bleeding off pressure through kill-job, blowout is eliminated just can continue operation.
