Quick connectors for high-voltage variable-frequency water pumps in mine environments

Abstract

The invention provides a quick joint for a high-pressure variable-frequency water pump in a mine environment, including a joint seat, a tapered groove C and a rubber pad; the joint seat is a cylindrical tubular structure, and an annular fixing seat is welded on the rear end surface of the joint seat, and The front side of the outer wall of the joint seat is provided with ten snap beads for matching with the card slot A in an annular array; the outer wall of the joint seat is welded with a stud at the rear side of the retaining ring, and the outer wall of the joint seat is A spring is sleeved between the stud and the ferrule. Because there is a tapered groove A on the front end of the joint seat, the jamming can be reduced when the joint body and the joint seat are connected to each other during use. Compared with the existing device, the connection of this device is smoother and more convenient; The setting of ferrule, stud and limit nut, the ferrule can be limited by tightening the limit nut. Compared with the existing device, this device can prevent the ferrule from moving due to unintentional touch when it is used, resulting in The joint main body and the joint seat are disengaged from each other.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection, and more specifically relates to a quick joint for a high-pressure variable-frequency water pump in a mine environment. Background technique [0002] A quick connector is a connector that can be connected or disconnected without tools. Quick connectors can be divided into: quick connectors for air, quick connectors for oxygen fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water and oil, and semiconductor quick connectors. [0003] For example, the application number: CN201210428006.X, the invention belongs to the field of pipeline connection, especially a quick connector for gas, liquid and other fluids and valves, including three major parts: a connecting body, a sealing ring, and a multifunctional movable sleeve. The large part structure can be freely assembled, disassembled and replaced...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a quick connector for a high-voltage variable-frequency water pump in a mine environment, to solve the existing problem that the connection is not smooth enough and convenient, and the end faces of the existing quick structure are all planar structures, especially in mines, etc. In an environment with limited lighting conditions, it is difficult to achieve fast alignment connection; moreover, the structure is not reasonable enough, and the existing quick connectors, such as snap-on connectors through snap beads, have not been equipped with corresponding protective structures. Inadvertently touching the ferrule during the process to displace the ferrule will easily cause the male and female parts of the joint to separate from each other; finally, the sealing performance is poor. After the existing device is connected, water leakage is prone to occur in the connection gap between the male and female heads question
