Key words: quick locking joints;Purifier Special joint; water connections
1 Introduction
Quick Connector - as water purifiers,Water Machine Connections between the various components of a waterway connecting device, with its fast, convenient generally well received by industry from various manufacturers to use, however, is unsatisfactory in all water purifier, direct drinking machine, water machine water seepage, leakage phenomenon in, basically, and "quick connector" has a direct relationship. "Connector" leakage, seepage water industry players engaged in for both a "psychological problem" (I, whether production, operation and use of both personal experience), even though the manufacturers are racking their brains trying to efforts to reduce and to overcome such problems from occurring, but it is still impossible for little effect, such leakage, water seepage, detached incidents continue to repeat the same mistakes, leading to a number of vendors talk about "leakage" pale, simultaneous complain about supporting the industry is not in place, "connector" technology technology lags behind development of the industry, can not find stable, safe, reliable, easy to use a special "connector."
(Patent application number: 200,910,273,056.3)
2 Background Art
Existing "Quick Connector" a long time, and by whom invented, but also when to enter the water purification industry by Wucongkaozheng, but the industry has become a fact seldom used, but there are two points to note: First, "joint" works and the basic structure of the pneumatic tool industry from the trachea connected devices, in principle, should be designed specifically for a special pneumatic tools parts, the road due to water and gas medium, pressure, etc.EnvironmentAnd working conditions has a different quality and quantity should be different from design; second water industry is currently no specific PE water pipe connecting the components of professional accessories in place, become an obstacle to development of the industry a major technical bottleneck.
The existing types of water purifiers and pure water machines commonly used by the lock-piece quick connector, in order to connect each unit filters filter out water bottles and as well as the need and the waterways connecting the various parts, water purifier system, water safety, Quick Connector plays a key role, according to incomplete statistics: 90% of the water leakage, water seepage is caused by the quick connector on its reasons: First, connector built-in O-ring rubber pipe diameter PE alone Side block means it can not withstand the pressure when the pressure increase resulting from chronic water seepage; second locking pieces through the assembly, testing, storage, transportation and installation of multi-channel program after locking deformation, locking pieces and drain off loading, resulting in PE face increased pressure when the water pipe was leaking off; third connector assembly dimensions on PE pipe concentricity, wall thickness, and forming a round very strict requirements, while the PE pipe is very difficult to mass-produced items at the same time universal to meet the requirements; fourth ultrasonic welding joints leak occurs welding, cold solder joint. These technology issues have a direct bearing on the normal use of quick connector, connector parts may be small but in the whole system plays a connected waterway running to protect the safety of important functions.
3 Development of content and basic principles of
The purpose of the development was aimed at the shortcomings of existing technologies used to provide a safer, more efficient operation, re-use does not affect the performance of quick locking joints.
The rapid development of locking joints are involved in are water purifier water purifier system, a connection device connecting waterways, including the seat tube, internal and external pipe kits and O-ring composed of rubber and formed around the combination of thread, internal and external synchronous precession, dense blocking tight linkage principle structure. The technical solution to be adopted is this: When PE pipe inside and outside the tube by a good package insert built-in a good O-rubber gasket after the tube socket, just outside the tube can be tightened cis-thread and lock washers compacted PE water pipes, in order to achieve the secondary pressure sealing washers and lock firmly PE pipes to ensure the joints are not in use, leakage, does not go beyond control.
4 Comparison with the existing technology
The development of fast locking connector with the existing lock-piece joints compared: ① the production process simplification, all the parts are a plastic injection molding mold without the need for secondary processing of ultrasonic welding; ② Quantity reduce costs, fewer parts, processing saving costs; ③ structure is more compact, non-locking pieces mounted or loose drain phenomenon; ④ installation more convenient, faster, you can simply shun the tightened; ⑤ repeated use will not affect the performance; ⑥ can better adapt to fluctuations in water impact pressure; ⑦ pairs of matching PE water pipe without special requirements, regardless of how the quality of PE pipes can be firmly sealed to achieve lock. As a result, greatly increasing water purifiers, water machine in the assembly process efficiency and the use of the waterway security.
5 Conclusion
The newly developed fast-locking connector, as the water industry, designed specifically for the common parts, its basic functional, the unique structure of novel, high reliability, low cost, can better adapt to the water purifier, water purifier whole computer system security requirements and to achieve the national standards to be implemented, "Household and similar use of drinking water treatment plant" test method validation program called the static pressure resistance, anti-cyclic water pressure, water pressure resistance and other technical indicators for blasting. With the application and popularization of the technology will surely improve the water industry, "quick connector" technology and to prevent water seepage, leakage, detached play an active role in promoting.
