Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] The lead liquid quantitative device of this specific embodiment is as figure 2 As shown, the housing 1 is included. The housing 1 is hollow, and the left part of the hollow part has a smaller diameter for accommodating the valve core 7; the right part has a larger diameter and is used for accommodating the valve stem 4. In addition, lead inlet 2 communicates with the position where the valve core 7 is accommodated at the left end; lead outlet 3 communicates with the position where the valve stem 4 is accommodated on the right.
[0032] The shape of the spool 7 is similar to that of a bolt, and includes two cylinders with different diameters. There is a section of external thread at one end of the small cylinder, which is used for fastening with the nut 8. One end of the large cylinder is provided with a notch, and the inser...
