Mouthful；The wall inner portion is divided into upper and lower two parts by dividing plate, and the center of the dividing plate is provided with truncated cone sealing knot
Structure, the top of the truncated cone sealing structure and bottom end opening and top end opening area are less than bottom end opening area, the circle
The bottom of taper type sealing structure is integrally formed to be installed on the dividing plate；The structure of cup holder is that cylindrical structure and top are opened
Mouth, bottom end seal, the side wall of the structure of cup holder is provided with opening, and the top of the structure of cup holder coincide and is installed on the frustum of a cone
The inwall of shape sealing structure, is provided with float, the identical truncated cone sealing knot of the float top end face shape in the structure of cup holder
The inwall of structure can simultaneously seal truncated cone sealing structure.
Preferably, the bottom of cylindrical support tube is installed on the junction of truncated cone sealing structure and dividing plate, described
The top of support tube is installed on the cover plate, and the side wall of the support tube is provided with passage.
What the present invention was produced has the beneficial effect that：Ingenious utilization float forms air cavity, float is combined with air cavity so that seawater
Do not contact with protected side valve part, solve the problems, such as seawater corrosion valve member.This apparatus structure is simple, simplifies setting in the past many
The mode of road valve member, its long service life.
