Quality identification method for metal hose joints - focus on microfluidic control technology
Due to the different quality of the internal materials of the hose pneumatic joints on the market, it is difficult for consumers to distinguish the advantages and disadvantages of the joints from the appearance.

Identify the quality can be obtained according to the standard
It is still difficult to completely distinguish the root cause of the fracture of the pneumatic joint. At present, the National Technical Quality Supervision Bureau has issued the recommended standards for sealing nozzles and hose standards. These two standards have relatively well defined the quality standards for pneumatic joints and hoses. In the event of unreasonable fracture of the hose joint, the consumer can go to the quality inspection department to test the twisting strength of the joint hose, the tightness of the joint valve core, and the strength of the joint material. If the content of the standard is not met, it is a quality issue and a strong evidence of the lawsuit.
Maintenance cannot be ignored
The length of time that metal hose pneumatic joints are used generally does not attract attention. However, long-term use of excessive frequency and improper maintenance will also pose a hidden danger to the joint breakage. Generally speaking, the service life of the joint is about 200,000 times, so it should be replaced in time after long-term use. Lightly close and lightly open, do not vigorously rotate the hose pneumatic joint knob repeatedly is also the key to maintenance.
The appearance of the hose pneumatic joint is difficult to distinguish
In order to pursue profits and reduce costs, many manufacturers have secretly reduced the material quality of their products, or used metal cast iron (easy rust) or zinc alloy (not anti-corrosion) as raw materials for the production of metal hose pneumatic joints. This can easily lead to the failure of the joint and hose quality, and the strength and sealing performance of the metal hose pneumatic joint can not meet the standard, which causes problems in the actual production and life use.
