Abstract

The utility model relates to an oil field delamination oil extraction equipment, in particular to a fluid control block-searching fluid switch, which comprises an external annular tube and a central axle tube arranged in the external annular tube. One end of the external annular tube is provided with an inner flight and the other end connects with one end of the piston tube. The other end of the piston tube connects with a ball seat shell, and the other end of the ball seat shell connects with one end of a lower joint tube. The other end of the lower joint tube is provided with an outer flight and a gland connects with the lower joint tube. A steel ball and an airproof component are arranged on the ball seat shell, and a boss is arranged on the inner wall of outer annular tube. The tube wall is provided with rail pin screw holes, and the surface of the external circle of the central axle tube is provided with a convex shoulder and a guide rail concave slot. A bearing is arranged on the convex shoulder and the spring covering the central axle tube is arranged between the bearing and the piston tube, and one end of the rail pin is arranged in the guide rail concave slot. The utility model has the essential advantages of four-layer control and reliable operation of the switch inverting mechanism.

Description

The water blocked switch device is looked in hydraulic control

Affiliated technical field:

The utility model relates to the equipment that the oil production by layer of a kind of oil field is used.

Background technology:

The water blocked switch device is looked in existing hydraulic control, and two types on plain edition and repeatedly repetition type arranged, and the plain edition derailing switch generally only is provided with and opens or closes two states, can only be used to control 2 layer positions; Repeat switch device repeatedly though can be used for layer position more than two, is realized repeatedly repeated liquid controlled reversing, and changement exposes, and is subject to the working environment variable effect, and the reliability of changement work can not be guaranteed.

Summary of the invention:

The purpose of this utility model is: the technical scheme that provides a kind of hydraulic control to look for the water blocked switch device, this derailing switch can be used for controlling four layer positions, and the state that initially opens or closes of four derailing switches of corresponding four layer positions can be set up arbitrarily, arbitrarily combination; Changement all is arranged in the derailing switch, helps guaranteeing the functional reliability of changement.

The technical solution of the utility model is: the water blocked switch device is looked in hydraulic control, comprise outer tube, place the central shaft tube in the outer tube, inlet opening and the groove of putting " O " RunddichtringO are arranged on the central shaft tube, one end of outer tube has internal thread, the other end is connected with piston tube one end, in the piston tube, the groove of putting " O " RunddichtringO is arranged respectively on the outer tube wall, one end of the other end of piston tube and ball seat shell is tightly connected, the other end of ball seat shell is connected with lower contact Guan Yiduan, the lower contact pipe other end has external screw thread, on the ball seat shell other end inwall groove of putting " O " RunddichtringO is arranged, pressure cap is connected with the lower contact pipe, be provided with steel ball and seal in the ball seat shell, on the inside pipe wall of outer tube boss is arranged, the screw that the dress track pin is arranged on the tube wall of outer tube, convex shoulder and guide track groove are arranged on the outer peripheral face of central shaft tube, bearing is arranged on the convex shoulder, the spring that is sleeved on the central shaft tube places between bearing and the piston tube, track pin one end that is contained in the track pin screw places the guide track groove, guide track groove on the central shaft tube outer peripheral face is symmetry status, three close with groove and other three close with groove symmetrical, a unlatching is opened with groove and another one and is used groove symmetrical, and these groove parts are communicated with.

Major advantage of the present utility model is: four different layers positions that can be used to control the oil field, the original state of four derailing switches of four different layers positions, corresponding oil field opens or closes and can set up arbitrarily, combination arbitrarily, and can repeatedly repeat commutation, the changement of switch is arranged on derailing switch inside, is not subject to the influence of operate outside environmental change, helps guaranteeing the functional reliability of switch changement, reduce fault, raise the efficiency.
