Deep-sea leakage-free underwater hydraulic joint capable of rapidly discharging seawater

Abstract

According to the deep-sea leakage-free underwater hydraulic connector capable of rapidly discharging seawater, the drainage hole is formed in the female connector, so that seawater is extruded and discharged from a cavity where the male connector and the female connector are in butt joint when the male connector and the female connector are in butt joint, and through the design that no ejector pin is exposed outside, no hydraulic oil leaks in the insertion and separation process of the male connector and the female connector; the problems of environmental pollution and oil waste caused by oil leakage in the butt joint process of the hydraulic joint are solved; through the design that the female head is provided with the drainage hole, the hydraulic connector achieves pressure compensation in the butt joint process and then can be applied to the deep sea environment, and the problem that the insertion and extraction force is too large due to the large internal and external pressure difference when the connector is inserted and extracted in the deep sea environment is solved; by means of the design that the 45-degree chamfer is formed in the inner edge of the end of the sliding sleeve limiting piece in the female connector sleeve to form the horn hole, the guiding effect can be achieved when the male connector and the female connector are in butt joint, and the problem that the butt joint efficiency is low due to the fact that no guiding exists when the male connector and the female connector are in butt joint is solved.

Description

technical field [0001] The invention belongs to the field of offshore petroleum engineering equipment, and in particular relates to an underwater hydraulic joint for deep sea leak-free and rapid seawater discharge. Background technique [0002] With the development of the world economy, various countries have gradually shifted their attention to the exploitation of oil and gas resources from the land to the ocean. The underwater production system is the mainstream mode for the development of marine oil and gas resources, which is developed according to the needs of the exploitation of marine oil and gas fields. When the underwater equipment of the underwater production system needs to be driven by hydraulic pressure, the underwater hydraulic joint, as the underwater equipment that can transmit hydraulic signals, will inevitably be applied to the underwater production system. The underwater hydraulic joint can realize the on and off of the hydraulic pipeline, plays a vital r...

Problems solved by technology

[0005] The object of the present invention is to provide a deep-sea non-leakage fast-draining seawater underwater hydraulic joint. The device can squeeze the seawater from the chamber where the male and female joints are docked when the male and female joints are docked by setting drainage holes in the female head. Discharge, which solves the problem that seawater enters the hydraulic pipeline during the docking process and affects the performance of other components of the hydraulic system; the device can realize the insertion and disengagement process of the male and female connectors through the design of the exposed thimble. No hydraulic oil leakage, which solves the problems of environmental pollution and oil waste caused by oil leakage during the docking process of hydraulic joints; the device can be designed with drainage holes in the female head, which not only makes the hydraulic joints more reliable during the docking process of male and female joints It has the function of quickly draining seawater, and it can also make the hydraulic joint realize pressure compensation during the docking process and can be applied in the deep sea environment, which solves the problem of plugging and unplugging of the joint in the deep sea environment due to the large internal and external pressure difference. The problem of excessive force; the device is designed to form a horn hole by chamfering the inner edge of the end of the sliding sleeve limiter in the female sleeve at 45 degrees, which can play a guiding role when the male and female connectors are docked, and solve the problem. The problem of low docking efficiency due to lack of guidance when the male and female connectors are docked; Realize dynamic and static sealing, and can achieve better sealing effect on the internal fluid before and after the hydraulic joint is docked
