Using the utility model of technique scheme, circular top plate is embedded in annular sidewall, convenient dismounting during cleaning, between be provided with sealing ring and improve air-tightness, it is to avoid escape after evaporating；Set first through hole and the second through hole can be respectively provided with different pipelines, purposes variation；Nut is positioned at above circular top plate can reinforce the first connector and the steadiness of the second connector installation, gas in container pressure can be monitored by the air gauge set by the first connector upper end, explosion-proof valve can when hypertonia releasing pressure automatically, improve security performance, audible alarm can be provided by external steam whistle, remind user to note；Joint set by second connector lower end can connect flexible pipe and facilitate liquid in evacuation container, by the ball valve set by the second connector upper end, and convenient operation.
Preferably, described first aperture, through hole upper end is less than aperture, lower end, described first through hole upper semisection cross section is circular, set first through hole lower semisection cross section is regular hexagon, described second shape of through holes is identical with the first through hole, described first connector is and the first through hole inner couplings, is provided with sealing ring between described first connector and the horizontal contact surface of circular top plate；Described second connector is to couple with the second through hole, is provided with sealing ring between described second connector and the horizontal contact surface of circular top plate.
First connector and the second connector couple with the first through hole respectively, are orthohexagonal structure by cross section, will not arbitrarily rotate, and install more stable, and the sealing ring set by contact surface horizontal with circular top plate further increases air-tightness.
Preferably, described explosion-proof valve safe pressure value is set as 2kpa.
Preferably, being waveform outside described annular sidewall, a height of 45mm of described annular sidewall, external diameter is 70mm.
Undulated design can increase frictional force, more convenient to use.
This utility model is compared to existing technology, more convenient to use, with pressure detecting and can releasing pressure automatically.
