1. Quick plug tube connector.
Also known as insert type pipe joint, including plastic type quick plug and all metal type quick plug.
Commonly used in pneumatic circuit rigid or semi-rigid nylon pipe, plastic pipe, polyurethane pipe connection. The maximum working pressure is 1.0MPa. The series pipe joint has the advantages of quick intubation, easy installation, reliable sealing, solid connection, beautiful appearance and so on.
When in use, the neatly cut pipe is inserted, fixed on the pipe joint with the elastic clamp ring self-bite, and sealed with the O-ring. When unloading the pipe, first press down the elastic clasp to facilitate the tube withdrawal. This kind of pipe joint has many kinds and complete specifications, and is the most widely used one in the hose joint.
The disadvantage of the quick-plug pipe joint is that the plastic is easy to age and is not resistant to pressure, resulting in the loosening of the clamp ring, the loss of the gas pipe or the leakage of the joint.
2. Quick screw connector.
Also known as cone lock type pipe joint or lock nut type pipe joint. The structure of the utility model is that a curved convex table is arranged on the outer cone of the joint body, the pipe is covered on the outer cone of the joint body when connecting the pipe, and then the nut is tightened to seal. With a wide variety of fittings and complete specifications, this type of fittings is the most widely used in high-end applications of fittings, especially in automation and sealing performance testing.
The utility model is applicable to the pneumatic pipe system of printing and dyeing light industry, automobile manufacturing line industry, food filling, water treatment, shipbuilding industry, chemical industry, etc. The pipe comprises Pu pipe, nylon pipe, polyurethane pipe, Teflon pipe, plastic pipe, etc.
The utility model overcomes the disadvantages that the quick-insert pipe joint is easy to age, the gas pipe falls off or leaks, and has the advantages of durability. However, the one-time use price of the fast screw coupling is faster, the plug-in coupling price is higher, and the cumulative price or long-term use cost is faster, and the plug-in coupling price is lower. It's worth it
3. Quick replacement of pipe fittings.
The utility model relates to a pipe joint which can be quickly disassembled and assembled without tools, and is especially suitable for pipes which are in urgent need of frequent disassembly. Such joints usually have unidirectional elements inside. When the joints are connected to each other, the steel balls are positioned and the gas paths on both sides are connected. After the connector is removed, the gas path is disconnected, and there is no need to install the gas supply switch.
There are internal threads, external threads, metric threads, cylindrical pipe threads, conical pipe threads, one end is a thread, the other end is a pagoda connector, both ends are a pagoda connector, both ends are a thread, etc. The joint body is made of brass or steel, and the surface of the brass joint is usually polished with nickel and chromium plating.
