Problems solved by technology

However, the inner spool of this quick connector has a conical surface structure, and the butt joint and separation seals are exposed in the flow channel, and impurities are easily enriched in the seals, thereby affecting the sealing performance; the conical spool makes the flow area smaller and the flow resistance increase
At the same time, the female joint housing provides a possible leak point for the two parts to be sealed by a seal

Embodiment 1

[0032] Such as Figure 1 to Figure 4 As shown, the present invention proposes a dry type quick joint with a large diameter, which includes a male joint (such as figure 2 ) and female connectors (such as image 3 ). Specifically, the male joint has a male joint housing assembly 1, a fixed valve core assembly 2, and a moving valve core assembly 3; the fixed valve core assembly 2 and the moving valve core assembly 3 form an the first channel of

[0033] The male joint housing assembly 1 includes the male joint housing 11, the male joint housing seal 12 and the outer seal 13 of the male joint; the outer housing 11 has a locking curved groove 111, and the inner cavity is provided with a fixed valve core assembly 2 and a movable The spool assembly 3; the fixed spool assembly 2 includes a fixed spool 21 and a fixed spool seat 22, and the rear part is fixed by a retaining ring; the movable spool assembly 3 includes a first movable spool 31, a first movable spool seal 32, the firs...

Embodiment 2

[0041] like Figure 1 to Figure 4 As shown, the male joint and the female joint rely on the sliding of the locking roller 63 on the female joint locking assembly 6 in the curved groove 111 on the male joint housing 11 to achieve docking and locking; the female joint locking assembly 6 passes through a set of circumferential steel Ball 64, guide ring 65 and steel ball fixing ring 66 realize the smooth rotation of operating hand wheel 62; guide ring 65 completes the circumferential direction support of the locking assembly, and steel ball fixing ring 66 compresses steel ball 64 in the circular groove to prevent steel ball The ball 64 comes out;

[0042] Other structures are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0044] like Figure 4 As shown, the male connector housing 11 is provided with a male connector housing locking curved groove 111 for locking the male connector and the female connector, which is used to constrain the movement track of the locking roller 63 and realize the docking of the male connector and the female connector; the male connector The locking curve groove 111 of the joint housing is a multi-segment curve, and the curve can be expanded into a horizontal line segment, a multi-segment obliquely downward straight line segment, a multi-segment obliquely upward straight line segment and a vertical line segment, or other types of curve segments in the same direction;

[0045] Other structures are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of fluid pipeline connection, in particular to a large-diameter dry-type quick connector, which includes a male connector and a female connector that cooperate with each other; the male connector includes a male connector housing assembly, a male connector fixed valve core assembly and a male connector. The joint moves the spool assembly; the female joint includes a female joint housing assembly, a female joint spool assembly and a female joint locking assembly; the fluid pipeline connection device adopts a flat head structure and a roller curved groove type quick locking docking method to realize Accurate and fast docking is achieved based on the respective sealing properties of the male / female joints, effectively realizing the internal flow of fluid in the flow channel set between the docking structures, simplifying the docking and unlocking operations, eliminating fluid leakage, improving the flow coefficient, and improving The design purpose of impurity resistance and field operation efficiency. The invention has the advantages of reasonable design, strong sealing performance, small internal fluid resistance, and each internal sealing member does not always contact the flowing working medium.

Description

technical field [0001] The invention relates to the technical field of fluid pipeline connection, in particular to a large-diameter dry quick connector. Background technique [0002] In a large flow fluid transmission system, in order to assemble, debug and maintain the system, it is often necessary to connect and disconnect the fluid. The joint devices in the prior art often add cut-off valves at both ends of the male joint and the female joint. The joints are only responsible for communication and sealing, and then the connection and disconnection of the fluid are controlled by operating the valve. This method not only increases the number, volume and cost of the equipment, but also has a certain amount of media leakage during the connection and disconnection process, especially for toxic, harmful, high-risk and precious fluid media, which will pollute the environment and waste materials. Operators have greater potential safety hazards. On the other hand, due to the exis...
