Description
Technical Field
The utility model belongs to the technical field of oil production equipment, especially, relate to a cable passes through ware with double seal structure.
Background
With the development of the petroleum exploration and development business in China, the development strength of offshore oil wells and low-pressure oil wells is getting greater and greater, and the electric submersible pump comprehensive oil extraction technology matched with the offshore oil wells and the low-pressure oil wells is rapidly developed. The cable crossing device is a device which is used for penetrating a tubing hanger and an upper flange on an oil production wellhead of an electric submersible pump and connecting an underground electric submersible pump with an aboveground power supply, changes the traditional cable crossing mode, and has the characteristics of good safety, high sealing performance, convenience in operation and the like.
However, the temperature and pressure resistance of the cable traversing device with the existing structure is not ideal, and under the condition of high temperature and high pressure, the strength of rubber in the cable traversing device is reduced, so that the rubber is deformed or damaged, and safety accidents such as poor sealing and leakage are easily caused. Therefore, the structure of the cable traversing device needs to be optimally designed, the temperature resistance and the pressure resistance of the cable traversing device are improved, and the sealing reliability of the cable traversing device is ensured.
Disclosure of Invention
An object of the utility model is to provide a cable passes through ware with double seal structure solves and passes through the poor problem of leakproofness that the ware is connected the position under high temperature high pressure.
In order to achieve the above object, the basic scheme of the utility model is: a cable crossing device with a double-sealing structure comprises a crossing device main body, a straight plug and a connecting screw cap used for fixing the crossing device main body and the straight plug, wherein the crossing device main body comprises a main body shell and a cable contact pin arranged in the main body shell, the straight plug comprises a front connector shell and a front connector arranged in the front connector shell, the front connector is matched with the cable contact pin, a lip sealing structure is adopted at the contact position of the main body shell and the straight plug front connector shell, an O-shaped sealing ring A is arranged between the main body shell and the front connector, and a connecting cavity of the front connector and the cable contact pin is in a conical shape.
Preferably, a straight plug positioning sleeve is arranged outside the straight plug.
Preferably, an O-ring B is provided between the front joint and the front joint housing.
According to the technical scheme, after the main body of the traversing device is connected with the straight plug, the connecting part of the main body and the straight plug adopts the combined action of the O-shaped sealing ring and the lip-shaped sealing ring to form a double sealing structure, so that the sealing effect of the cable traversing device in a high-temperature and high-pressure environment is enhanced; meanwhile, the front connector is in interference fit with the contact pin to form an interference sealing structure, so that the grabbing force between the front connector and the contact pin is increased, the sealing effect is improved, and the device is suitable for popularization and application.
