Problems solved by technology

[0003] There are many problems with the pipe hoop connection method currently used: first, the steel pipe hoop is connected to the synthetic material pipe (such as polyethylene pipe) by wires, and the connection must be kept straight, which is labor-intensive and material-intensive, and the construction is difficult; When the synthetic material pipe is bent or the installation error is large, it is most likely to break and leak; the third is that the steel pipe hoop is expensive
Another commonly used is the flange joint, but the quality requirements of the flange welding are relatively high. The weld must not only be strong and reliable, but also have strong sealing performance. Docking, the connected round hole does not correspond

Embodiment 1

[0025] Such as Figure 1-2 As shown, a new type of water-cooling system joint invented in this example includes a double-ended screw 1, a lock nut 3, a bushing 2, a groove 4 and an O-ring 5, and the inside of the double-ended screw 1 is a hollow screw. A bushing 2 is provided between the stud screw 1 and the lock nut 3. There are two bushings 2. The two bushings 2 are conical. The center of the bushing 2 coincides with the axis of the stud screw 1. One The shape of the conical surface of the bushing 2 is the same as the inner shape of one end of the stud screw 1 , and the shape of the conical surface of the other bushing 2 is the same as the inner shape of one end of the lock nut 3 .

[0026] The two conical bushes 2 are arranged in a way that the cone bottoms are facing each other. The top of one bush 2 protrudes into one end of the stud screw 1 for sealing butt joint, and the bottom of one bush 2 is docked with the bottom of the other bush 2. , the bottom of the other bushi...

Abstract

The invention relates to the field of water cooling systems in power electronics, in particular to a novel water cooling system joint. The joint comprises a double-end screw and a locking nut, wherein the interior of the double-end screw is a hollow screw; two tapered bushings are arranged between the double-end screw and the locking nut; the circle centers of the bushings are superposed with the axis of the double-end screw; the tapered face shape of one bushing is as same as the internal shape of one end of the double-end screw; and the tapered face shape of the other bushing is as same as the internal shape of one end of the locking nut. The joint has the characteristics of reliable, reasonable and simple structure, simplicity in operation, low cost and the like.

Description

Technical field: [0001] The invention relates to the field of water cooling systems in power electronics, and more particularly relates to a novel water cooling system joint. Background technique: [0002] Water cooling system is currently widely used in the cooling of HVDC converter valves. The performance of the pipe joints of the water cooling system directly affects the sealing and connection performance of the water system. In practical engineering applications, leakage and blockage accidents caused by water joints are not uncommon. Therefore, the reasonable design and selection of water pipe joints are very important for the long-term operation of diverter valves. [0003] There are many problems with the pipe hoop connection method currently used: first, the steel pipe hoop is connected to the synthetic material pipe (such as polyethylene pipe) by wires, and the connection must be kept straight, which is labor-intensive and material-intensive, and the construction is ...
