Embodiment Construction
[0042] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0043] The present invention consists of figure 1 As shown, the integrated design is adopted, and all parts are installed on the substrate to form a highly integrated valve group.
[0044] The primary valve assembly 8 is in the form of vulcanized rubber, and the fluorine rubber is vulcanized on the metal frame. The primary valve assembly 8 adopts a reverse unloading structure, and a cylindrical stepped cavity is processed inside, and the diameter of the upper cylindrical cavity is smaller than that of the lower end. The diameter of the cylindrical cavity is 0.8-1.1mm, and two oblique holes are opened at the boss on the top of the first-stage valve assembly. The diameter of the oblique holes is 0.5-0.8mm. The cylindrical stepped cavity in the direction runs through each other.
[0045] The primary valve assembly 8 has a sealing groove on the outer surface, and a seal...
