First, the quick connector can be divided into two types according to the structure: open and close at both ends, open at both ends, and single open and close.
1. Open and close at both ends
When not linked: When the ferrule of the mother body moves to the other end, the stainless steel beads automatically roll outward, the child body is disconnected by the action of the valve spring force of the mother body and the child body, and the valves of the child body and the mother body are closed respectively. , Block fluid flow instantly.
When linked: When the child body is inserted into the mother body, the ferrule returns to its original position under the action of the spring, and the steel ball rolls to lock the child body tightly connected. At the same time, the valve of the mother body and the child body pushes each other to open, fluid flow, O-ring Can completely block fluid leakage.
2. Open ends
Not linked: When the ferrule of the mother body is pushed to the other end, the steel ball automatically rolls outward, so the child body is removed; because there is no valve for the child body and the mother body, the fluid flows out.
When linking: When the child body is inserted into the mother body, the ferrule is pushed to the previous position by the force of its spring, causing the steel ball to lock, and the fluid flows, and the O-ring in it prevents liquid leakage.
3.Single open and closed
Not linked: When the ferrule of the mother body moves to the other end, the stainless steel beads automatically roll outward, and the daughter body is opened by the reaction force of the valve spring, and the valve can automatically close to block the fluid flow.
When linking: When the child body is inserted into the side of the mother body with the ferrule, the valve is opened to cause fluid flow, the gasket is pushed back to the original position by the force of the spring, and the stainless steel beads will lock to ensure the child / parent body connection. Completely blocks fluid leakage.
Second, the related functions of the quick connector
Exchange function: Attachment to pneumatic, hydraulic tools, air cylinder, hydraulic cylinder, metal mold related machinery.
Maintenance function: computer cooling device, die-casting machine cylinder maintenance.
Test function: test of vacuum, pressure resistance, leakage, operation, etc.
Conveying function: conveying, conveying, and conducting functions of solids such as bolts and nuts.
Filling function: inert gas, nitrogen, LPG, carbonic acid.
Connection function: fixed parts for fishing rods, compact laser records, connections other than mobile operations, and fluid transfer applications.
Why use a quick connector
1. Save time and effort: When disconnecting and connecting the oil circuit through the quick connector, the action is simple, saving time and labor.
2. Fuel saving: When the oil circuit is broken, the one-way valve on the quick connector can close the oil circuit, and the oil will not flow out to avoid loss of oil and oil pressure.
3. Environmental protection: When the quick connector is broken and connected, oil will not leak and protect the environment.
4. The equipment is set to zero, which is convenient for transportation: large-scale equipment or hydraulic tools that need to be carried easily are transported after being disassembled using quick connectors, and assembled after reaching the destination.
5. Economy: The above advantages have created economic value for customers.
How to choose a quick connector
1. fluid type and temperature (please select the quick connector of the body material and sealing material that is suitable for the fluid type and temperature)
The proper body material and seal material are different depending on the fluid. For example, the quick connector is air. Steel is recommended. Brass or stainless steel is used for water.
2. the pressure of the liquid (please select a quick connector suitable for the pressure resistance of the fluid pressure)
The pressure of the tritium fluid is also the key to selecting a quick connector. Hydraulic quick couplers are serialized between 5.0Mpa (51kgf / cm²) and 68.6Mpa (700kgf / cm²). Corresponding to pressure resistance characteristics, the structure of quick couplers is also different.
3. Structure of automatic opening / closing valve (please select the quick connector of valve structure suitable for piping application)
For the structure of the valve, there are two-way switch type, one-way switch type and two-way open type. In addition to the two-way switch type, fluid flows out of the pipe during separation. So please pay attention.
4. The use environment of the quick connector (please select the quick connector of the structure and material suitable for the use environment)
Consider the type, body material, and sealing material of the quick connector in consideration of the humidity conditions, dust conditions, and the use environment that are prone to corrosion.
5. Make sure the selected quick connector connection thread is consistent
During the use of products with different brands, it is best to use the male and female of the same brand together. If it is necessary to cross-use, it is best to consult the technical staff of the product supplier before use, and then use it after confirmation.
6. Shape and size of the installation (please order the product after determining the final shape and size)
Please determine the model and material of the quick connector, and specify the assembly shape and size corresponding to the characteristics of the piping. Please note that size is related to fluid flow.
Five, quick connector exploded view and exploded description
It comprises a female connector mother body, a through hole is arranged on the mother body, a steel ball is embedded in the through hole; a male connector cylinder, a groove is provided on the surface of the cylinder body; a card sleeve; the female connector mother body and the male connector cylinder are sealed and matched, The steel ball on the mother body is clipped into the groove on the surface of the cylinder; the sleeve is sleeved on the outer surface of the female connector female body, and is characterized in that it further comprises a pull sleeve, which is arranged on the surface of the male connector cylinder, and It is connected with the ferrule on the female connector by its internal thread.
