Preferably, the decrement of the O-ring seal is 20% ~ 30%.Top cover and casing in the utility model
Between sealing belong to static seal, better seal effect can be ensured using larger decrement.
Preferably, the top cover is integral type, and the top cover is provided with indentation.Integral type top cover is designed to avoid leak
Gas, further lifts the sealed horizontal of casing, and it is smaller to bear pressure on top cover at indentation, when box house pressure anomaly
Pressure release passage can be used as, prevents box house pressure from causing very much top cover to wash even casing blast open greatly.
Preferably, the indentation is gate, and gate indentation is in box house appearance of abnormal pressure as pressure release passage, door
Type indentation opens release pressure, avoids box house pressure from washing very much part or whole top cover open greatly, prevents rupture of case to operation
Person damages, and prevents during the short trouble of loop that high temperature and high pressure gas are burnt operating personnel, and simple in construction, easy to process, property
Valency is workable than high.
Compared with prior art, the beneficial effects of the utility model are：
The utility model ZW20 on-pole switch casing proof mechanism of water, including casing, top cover and seal, the top cover are set
In the top of casing, the seal is located between casing and top cover, and the casing is provided with convex portion, and the seal is provided with recessed
Portion, the convex portion are engaged with the recess, and the top cover is integral type, and top cover is provided with gate indentation.The setting of convex portion can
Prevent accumulation of the moisture in gap location, convex portion is engaged with recess assigns casing good sealing, when can avoid cooling outside
Moisture enters casing corrosion box house mechanism；Being designed to of integral type top cover avoids gas leakage, further lifts the close of casing
Water shutoff is put down；Gate indentation can be used as pressure release passage in box house appearance of abnormal pressure, avoid box house pressure too favourable opposition
Top cover is opened, prevents rupture of case from being damaged to operator, prevents during the short trouble of loop that high temperature and high pressure gas are burnt operator
Member, and it is simple in construction, it is easy to process, it is cost-effective, it is workable.
