Abstract
The utility model relates to a blowout prevention ball valve in the well head which is created mainly to solve the problem of being unable to control the blowout during the operation of an oil well, and the utility model is characterized in that an upper joint(1) and a lower joint(2) are respectively adopted by the external screw thread and the internal screw thread of the mouth piece of the oil pipe, a jacket is screwed between the upper joint(1) and the lower joint(2), a lower ball valve seat(5) is mounted on the lower end of the internal hole of the jacket(4), an upper ball seat ring(6) and a lower ball seat ring(7) are respectively embedded at the lower end of the upper joint(1) and the upper end of the lower ball valve seat(5), a ball valve core(8) is provided between the upper ball seat ring(6) and the lower ball seat ring(7), the ball valve core(8) is in fixed connection with a valve stem(3), the valve stem(3) penetrates the side wall of the jacket(4), and the jacket(4) is in sealed connection with the upper joint(1), the lower joint(2), the valve stem(3) and the lower ball valve seat(5). The blowout prevention ball valve in well head can be quickly positioned onto the oil pipe during the blowout to control the blowout in a short duration and has advantages of the simple structure and convenient operation.
Description
Technical field:
Used a kind of control blowout instrument, especially well head blowout prevention ball valve when the utility model relates to oil-water well operation in the oil recovery field, oil field.
Background technology:
In the oil recovery field, oil field, often oil-water well is carried out operation, when oil-water well, because the pressure of downhole oil or water through regular meeting the blowout phenomenon takes place.Running into blowout does not at present have special-purpose quick control tool, thereby control blowout that can not be very fast, causes environment pollution, and the labor intensive material resources influence ordinary production.
The utility model content:
The problem of control blowout that can not be very fast when solving the oil-water well operation, the utility model provides a kind of well head blowout prevention ball valve, this well head blowout prevention ball valve can be quickly installed on the oil pipe of blowout, controls blowout at short notice, has characteristics simple in structure, easy to use.
The technical solution of the utility model is: this well head blowout prevention ball valve comprises lower contact, last lower contact matches with the external screw thread and the internal thread of oil pipe termination respectively, overcoat has been threaded between the last lower contact, overcoat endoporus lower end is connected with down ball valve seat, the lower end of top connection reaches down, and the upper end of ball valve seat is inlaid with the lower ball base circle respectively, between the last lower ball base circle ball valve core is arranged, the ball valve core links to each other with valve rod, valve rod passes the sidewall of overcoat, overcoat and last lower contact, valve rod and all sealings between the ball valve seat down.
Above-mentioned ball valve in-core is equipped with interior cover; Under reaching, overcoat and last lower contact, valve rod between the ball valve seat sealing ring is arranged all; The termination of valve rod has the allen wrench hole, and the end face of valve rod aligns with the sidewall face of cylinder of overcoat.
The utlity model has following beneficial effect: owing to take such scheme, during underground work, as run into blowout and can be connected this ball valve on the oil pipe fast, rotary valve rod is closed ball valve then, just can control blowout effectively at short notice, simple in structure, easy to use.This ball valve also can be applicable in the middle of the clean-out service in addition.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-top connection among the figure, 2-lower contact, 3-valve rod, 4-overcoat, ball valve seat under the 5-, 6-upper ball base circle, 7-lower ball base circle, cover in the 8-ball valve core, 9-, 10-sealing ring, 11-allen wrench hole.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this well head blowout prevention ball valve comprises lower contact (1,2), last lower contact (1,2) match with the external screw thread and the internal thread of oil pipe termination respectively, the overcoat 4 that has been threaded between the last lower contact (1,2), overcoat 4 endoporus lower ends are connected with down ball valve seat 5, the lower end of top connection (1) reaches down, and the upper end of ball valve seat 5 is inlaid with lower ball base circle (6 respectively, 7), between the last lower ball base circle (6,7) ball valve core 8 is arranged, cover 9 in being equipped with in the ball valve core 8, ball valve core 8 fixes with valve rod 3, and the termination of valve rod 3 has allen wrench hole 11, and the end face of valve rod 3 aligns with the sidewall face of cylinder of overcoat 4.Valve rod 3 passes the sidewall of overcoat 4, and overcoat 4 is with last lower contact (1,2), valve rod 3 and between the ball valve seat 5 sealing ring 10 is arranged all down.
During underground work, as run into blowout and this ball valve can be connected on the oil pipe fast, rotary valve rod is closed ball valve then, just can control blowout effectively at short notice, and is simple in structure, easy to use.This ball valve also can be applicable in the middle of the clean-out service in addition.
