The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The integral structure of a kind of liquefied natural gas filling panel with dust boot of the present utility model as depicted in figs. 1 and 2, comprises front protective cover 2 and filling panel 1; Protective cover 2 before the front termination of described filling panel 1; Described front protective cover 2 is the box-like of five face closure recording quantity, described unlimited one side is adjacent to described filling panel 1, rotary connection by pivot pin with the upper end of described filling plate face 1 in the upper end of described front protective cover 2, the both sides of described front protective cover 2 are connected with described filling plate face 1 locking by buckle 5.
Wherein, the described liquefied natural gas filling panel with dust boot also comprises rear defence guard shield 3, the rear termination rear protecting cover 3 of described filling panel 1, rotary connection by pivot pin with the upper end of described filling panel 1 in the upper end of described rear defence guard shield 3, the both sides of described rear defence guard shield 3 are connected with the side plate 11 that is connected to filling panel 1 both sides.Between described rear defence guard shield 3 and described side plate 11, by butterfly spiral shell 31 is female, be connected.
During assembling, by the position, space (reserved air filling gun adds liquid space) at construction machinery and equipment with dust boot LNG filling erecting of panel, rear defence guard shield 3 is screwed with the panel 1 of annotating and is adjacent to, locking fly nut 31, again front protective cover 2 is screwed with the panel 1 of annotating and is adjacent to, last fastening side buckle 5(metal buckle body is welded in rear defence guard shield side, hooks shape welding hook in front protective cover side).During liquid feeding, open buckle 5, before outwarding winding, protective cover 2 reserves and adds liquid space and can carry out liquid feeding with air filling gun.During maintenance, if front protective cover 2 needs maintenance, open buckle 5, before outwarding winding, protective cover 2 reserves space for maintenance; If rear defence guard shield 3 needs maintenance, open buckle 5, turn on fly nut 31, the rear defence guard shield 3 of outwarding winding reserves space for maintenance, now also front and back protective cover and the hinge 4 that is welded on their upper surfaces can be taken down together, be exposed filling panel 1 completely, to needs, maintenance department overhauls respectively.
