Introduction to Quick Plug Connectors
Quick plug connectors are a convenient plug and play connection method, especially in some difficult space situations where tracheal connections are very inconvenient, which can better demonstrate the superiority of quick plug connectors. Quick plug connectors are divided into the following types: 1. Small; 2. Standard type; 3. Metal type; 4. Stainless steel type; 5. Flame retardant type; 6. Composite type; 7. Drum joint assembly.
product mix
The quick plug connector for bus water supply is designed as a spinning cone tube, mainly composed of a locking tube, an inner shrink tube, and a rubber sealing ring. Its feature is that the extended part of the connecting tube is an internally contracted tube integrated with the connecting tube, the middle section of the internally contracted tube is the tube body, the outer thread section is between the tube body and the connecting tube, and the other end of the tube body is the locking section, which is in the shape of a bell mouth and has multiple longitudinal slots. The elastic horn sealing ring is placed inside the horn mouth port of the locking section, and the outer part of the inner shrink tube is fitted with a locking tube. The locking tube has internal threads that match the external thread section of the inner shrink tube, and the outer diameter is the same as the outer diameter of the horn mouth of the locking section of the inner shrink tube.

working principle
Connect the tail end of the connecting pipe to the ground water supply pipe. Connect the elastic horn sealing sleeve of the quick connector to the water pipe on the bus, hold the handle and rotate the locking tube. The inner shrink tube moves inward relative to the locking tube, and the inner horn of the locking tube compresses the locking section of the inner shrink tube. The longitudinal groove of the locking section is reduced, so that the locking section presses the elastic horn sealing sleeve tightly. The elastic horn sealing sleeve is tightly combined with the water pipe on the bus, thus completing the docking work of the water pipe. When unloading the pipe, rotate the handle in the opposite direction to lock the pipe backwards, restoring the locking section of the inner shrink tube to its natural state, and the elastic horn sealing sleeve to its natural state, making it easy to pull out the quick connector.
Product advantages
1. The sealing ring is designed in the shape of a horn mouth, which enables the connection between the station water supply pipe and the passenger car water supply pipe in a short time (2-3 seconds).
2. Reduce the labor intensity of the operators by simply holding the handle and rotating it to complete the docking work. When unloading the pipe, simply gently rotate the handle in the opposite direction to quickly separate the joint from the water pipe on the bus.
3. The quick plug connector will not detach on its own during the process of replenishing water to the train, saving water resources.
