Description
Technical field
The utility model is related to a kind of seawater isolating device.
Background technology
Underwater structure would generally set a screw down nonreturn valve on gas exhaustion line, prevent inwelling from entering structure
In thing, but in actual use, screw down nonreturn valve long period of soaking in the seawater, causes holddown spring to corrode seal failure,
Seawater is penetrated into works.
Utility model content
The utility model proposes a kind of seawater isolating device, can thoroughly solve discharge screw down nonreturn valve and be asked by seawater corrosion
Topic, can prevent protected side valve part by seawater corrosion, it is to avoid seal failure after long-term use with gas exhaustion line under water
Problem.
What the technical solution of the utility model was realized in：
A kind of seawater isolating device, including barrel, cover plate, base plate, glass stand, float and dividing plate, the barrel top and bottom
End is sealed by cover plate and base plate respectively, and the cover plate is provided with gas exhaust piping interface, and the base plate is provided with seawaterline and connects
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 are 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 utility model was produced has the beneficial effect that：Ingenious utilization float forms air cavity, and float is combined with air cavity so that
Seawater is not contacted with protected side valve part, solves the problems, such as seawater corrosion valve member.Present apparatus simple structure, simplifies and sets in the past
The mode of multiple tracks valve member is put, its long service life.
