Embodiment Construction
[0026] like figure 1 Shown, the steps of its preparation process are as follows:
[0027] First, blow the piston shell with a nipper as the inner layer of the jacket, as shown in (a);
[0028] Second, after the small head is blown out, a glass tube is externally connected and melted, as shown in (b);
[0029] Third, open an opening on both sides of the shell, and then connect two glass tubes of equal length vertically as the inner branch pipes. The distance between the ports of the two inner branch pipes should be slightly smaller than the inner diameter of the outer glass tube of the piston jacket. Plug the two pipes tightly, as shown in (b);
[0030] Its four, one end of the glass tube that melts and seals is blown into a glass ball, as shown in (c);
[0031] Fifth, the big head is also blown into a glass ball, as shown in (d);
[0032] Sixth, cut off a part of the glass balls at both ends on the flame, and put on a glass tube of moderate length as the outer layer of the...
