1. The user is selected according to reasonable use requirements and characteristics of joint fast sub models.(including working pressure, the nature of the medium and the flow rate, temperature, corrosive and environment temperature, quantity and pipe connection, etc.)
2. If users need to connect one end of the direct and hard tube welding should pay attention to the following points:
(1) Using the special hook will be set inside the rubber sealing ring out, after being welded joint cool completely, then insert ring into the set inside.
(2) If it does not have the special hook, also can use wet cloth or cotton yarn with set inside the inner diameter of the sealing ring, in order to prevent the damage of high temperature welding sealing performance.
(3) Rapid not placed in the electrical conductor, such as metal plate, in order to avoid breaking current burn out internal, affect the sealing performance and accuracy.
3. The ball joint sphere (sub) and cone (box) protection should be paid attention to in the use and transportation, do not scratch or collision, so as not to affect even the sealing of the connection.
4. Correctly selecting model and reasonably fast connection for installation, is to improve the service life of the two important factors.
