Background
The pipeline joint is a connecting tool between pipelines and is a connecting point between an element and the pipelines, wherein the element and the pipelines can be disassembled and assembled. Plays an indispensable important role in the pipe fitting, which is one of the two main components of the hydraulic pipe.
Because the pipe joint belongs to a detachable connecting element, the pipe joint meets the requirements of normal connection stability, strong sealing property, reasonable size, small pressure loss, good process performance and the like, and also meets the requirement of convenient disassembly and assembly. Thus, the small pipe joint is not to be overlooked, since its presence only supports the presence of the entire hydraulic system.
Pipe joints are of various types, and common pipe joints can be generally divided into hard pipe joints and hose joints. If the connection mode of the pipe joint and the pipeline is divided, the hard pipe joint has three types of flaring type, clamping sleeve type and welding type, and the hose joint is mainly a fastening type hose joint.
In the water-cooling circulating system, cooling water is conveyed to a terminal of an experimental device accessory through a main pipe by a pump set and then enters the experimental device through a branch pipe reserved on the terminal. The terminal is connected with the branch pipe, and the branch pipe is connected with the device through the pipe joint.
Common water pipe joints used in water cooling cycle processes are: 1. the flange type pipe joint is tightly connected, but has larger size and fussy operation, needs larger space for operation, and is suitable for being used for high-water pressure pipelines with larger pipe diameter; 2. the VCR pipe joint is convenient to operate, has smaller size, but is only suitable for small-diameter pipelines; 3. the quick-insertion type pipe joint is simple to install, convenient to operate and small in size, but after the quick-insertion type pipe joint is used for a long time, a pipeline is easy to block, and the quick-insertion type pipe joint is suitable for a pipeline with a small diameter; 5. the cutting sleeve type pipe joint is convenient to connect, cannot be stressed, is easy to leak water, and is suitable for small-pipe-diameter low-water-pressure pipelines; 6. the threaded connection type pipe joint is convenient to operate and small in size, but is easy to leak when the water pressure is high.
According to the experimental requirement, the pipe diameter of a branch in the water-cooling circulation system is not large, and in addition, the pipe joint has the limitation of appearance, size, position and the like. Therefore, in the water-cooling circulation system, the terminal is in threaded connection with the pipe joint of the branch pipe commonly, the interior of the pipe joint is sealed by adopting a conical surface, the connector has good sealing performance and is convenient to operate, and the required operation space is small. However, after the pipe joint is disassembled for several times, the sealing surface is damaged, the sealing performance is reduced, water seepage occurs, and the pipe joint needs to be replaced. And the plane O-shaped sealing ring is adopted for sealing, so that the disassembly can be realized for many times. However, under a higher circulating water pressure, on one hand, the O-shaped sealing ring is easy to be washed away, so that the pipeline is blocked; on the other hand, the pipe joint is easy to have water seepage.
The pipe joint has high requirements for the experiment water-cooling circulation system, the pipe joint is required to bear high circulating water pressure and circulating water temperature, the pipe joint can be detached for many times, the sealing performance is high, and the performance is stable. In addition, the pipe joint has requirements for shape, size, position, etc., which cannot be met by the existing pipe joints.
