Abstract
The utility model belongs to the technical field of LNG liquid adding machines and particularly relates to a connecting device for an air return gun of an LNG liquid adding machine. The connecting device comprises an air return gun seat, an air return gun connecting block and an air return port connector. The air return gun seat is fixed at the inner step of the air return gun connecting block through a screw. The air return port connector is welded to one side of the air return gun connecting block. The other side of the air return gun connecting block is fixed on the shell of the liquid adding machine through a screw. The air return gun connecting block is of a structure similar to an 'inverted n' shape. A seal ring is disposed between the air return gun seat and the air return gun connecting block. The connecting device has the advantages that the air return hose of the LNG liquid adding machine is integrated with the air return gun by connecting the air return gun seat with the air return port connector through the air return gun connecting block, the connecting is simple and compact in structure, good in sealing performance and low in cost, welded junctions are reduced effectively, possible leakage points are reduced, a workshop assembling process is simplified, production efficiency is increased, material waste is avoided, and attractiveness and elegance are achieved.
Description
Technical field
The utility model belongs to LNG liquid filler technical field, relates in particular to a kind of connection set of LNG liquid filler return-air rifle.
Background technique
LNG is a kind of clean, efficient energy, and along with the development of China LNG automobile industry, to the demand of LNG gas station, also in continuous increase, LNG liquid filler is used widely day by day.At present, the return-air gun platform of LNG liquid filler and gas returning port are to be assemblied in respectively liquid filler casing outside, in the time that LNG liquid filler assembles, need first with screw, return-air gun platform to be arranged on liquid filler cabinet shell, again gas returning port flange plate and gas returning port joint are welded, then be fixed on liquid filler shell by the screw hole on gas returning port flange plate, finally carry out at box house by threeway and elbow, therefore have multiple tracks weld bond, easily damage, cause leakage, and maintenance difficult, waste material.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of simple and compact for structure, good seal performance, easy to use and with low cost, realize the connection set of LNG liquid filler return-air flexible pipe and the integrated LNG liquid filler of return-air rifle return-air rifle, effectively reduce weld bond, reduce the leakage point that may cause, and simplify the flow process of workshop assembling, avoided the problem of waste material.
The technical solution adopted in the utility model is:
A kind of connection set of LNG liquid filler return-air rifle, it is characterized in that: comprise return-air gun platform, return-air rifle contiguous block and gas returning port joint, described return-air gun platform is fixed by screws on the interior step of described return-air rifle contiguous block, described gas returning port joint is welded on a side of described return-air rifle contiguous block, and the opposite side of described return-air rifle contiguous block is fixed by screws on the shell of liquid filler.
Further, described return-air rifle contiguous block is class " recessed " character form structure.
Further, between described return-air gun platform and described return-air rifle contiguous block, be provided with seal ring.
The beneficial effects of the utility model are: the utility model links together return-air gun platform and gas returning port joint by return-air rifle contiguous block, have realized the integrated of LNG liquid filler return-air flexible pipe and return-air rifle; The utility model is simple and compact for structure, good seal performance, easy to use, with low cost, improve the performance of enterprises, effectively reduce weld bond, reduce the leakage point that may cause, and simplified the flow process of workshop assembling, improved manufacturing efficiency, avoid waste material, and more elegant in appearance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
