The principle of connection in Lock Quick Connect: The key to Lock Quick Connect lies in the sliding groove on the male end; once the mating arm on the female end is connected, its cam can get trapped in this sliding groove from any angle, thereby ensuring a secure connection. In the figure below, we can see that at position Figure 2, the surface is smooth, which does not affect the insertion of the male end. 02— Locking quick-connect standards: These quick connectors are simple and efficient, which is why they account for a very large share of the market in industrial connections. For this reason, our products need to take into account standard interoperability in the market, especially the compatibility of well-known brands in international markets. OPW brands: KAMLOK, AUTOLOK; DIXON brands: EZlink (boss-lock), Vent-lock ； And all of these correspond to the business description provided by the U.S. Commerce Department: A-A-59326B. Products that meet this description are widely used in the petroleum and water treatment industries. As for the domestic standard number for quick connectors on hoses, it is GB16693-1996; although this standard also provides descriptions of the product dimensions, there are significant differences in the details. 03—SYK Locking Connector: The locking connectors produced by Siyukao Company are manufactured in strict accordance with the specifications outlined in A-A59326B; careful selection of materials and precise control of tolerances ensure the reliability of these products. The standard models are as follows: Joint material: 316 stainless steel, T6 aluminum, CW617N brass, polypropylene. Pressure rating/connection sizes: Connection sizes 1/2” 3/4” – 2” 2” 3” 4” 5–6” 8”. Operating pressure (PSI): 150, 250, 150, 125, 100, 75, 50. Product seals: NBR/EPDM/FKM/fluorocarbon-coated PTFE seals. Special models: Reducer joints. Disadvantages of open-type quick connectors: The lock-type quick connectors with cam-slot mechanisms are, by definition, open-type quick connectors. Since it disconnects, the pipelines at both ends become connected to the outside environment, which may cause contamination of the pipelines ； Alternatively, after the transmission is complete, the medium in the hose is discharged directly, resulting in waste of resources and environmental pollution. Conclusion: For those in the pipeline connection industry, open-type quick connectors are already well-known. This introduction to Lock quick connectors is intended to lay the groundwork for self-sealing dry-type quick connectors. To meet the environmental requirements of the chemical industry, as pipelines are upgraded, self-sealing dry connectors will become a trend in the future. The Kay-Dry quick connect developed by Siyukao Fluids will fit perfectly with the original Locke quick connects, providing the most convenient and fast way to ensure no leaks on site!
