Gu knob, welding seat ring is provided with a separable closure, the periphery of closure is evenly provided with multiple U-shaped grooves, described
Groove matches with fix bar, and screwing tightening knob can firmly cover closure on welding seat ring, also be set on closure
There is a relief valve, gas is discharged by relief valve when air pressure is too high in container, an air gauge, the gas are additionally provided with closure
Pressure table is used to measure gas in container pressure size.
As the utility model preferred embodiment, the quantity of described U-shaped connector is no less than 4.
As the utility model preferred embodiment, described closure is solid metal lid, lid thickness 2-4cm it
Between.
Comprehensive manhole assembly of the present utility model is made up of welding seat ring and closure, and welding seat ring and closure are each other
Conveniently, gas discharge unnecessary in container can be prevented container inner pressure by the relief valve set on closure for independent and opening and closing
Excessive, the air gauge set on closure can show air pressure in container in real time, be easy to understand situation in container.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
