Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the utility model provides a suction structure, including breathing pipe 1 and the leak protection gas structure of setting in breathing pipe 1, enable to be the zonulae occludens state between breathing pipe 1 and the high pressure side equipment through the leak protection gas structure, leak protection gas structure and breathing pipe 1 are the integrated into one piece structure. The utility model discloses in, the high pressure side equipment is the cylinder, and the knockout is connected to 1 opposite side of breathing pipe. The side of the air suction pipe 1 connected with the liquid separator is a low-pressure side. Through forming the pressure differential in breathing pipe 1, and keep cylinder one side to be the high pressure side all the time, knockout one side is the low pressure side to can guarantee in the operation, can not lead to the liquid refluence because of knockout one side pressure height.
Through the arrangement of the air leakage prevention structure, the air suction pipe 1 can be tightly connected with the air suction port of the air cylinder, so that the pressure reduction at the connection part caused by air leakage is prevented, and the backflow is prevented; in order to reduce the easy clastic problem that produces of the process of the sealing washer of impressing after 1 installation of breathing pipe, design breathing pipe 1 and leak protection gas structure into an organic whole structure, need not to carry out the process of impressing of sealing washer again behind installation breathing pipe 1, not only avoided the process of impressing to easily produce clastic problem, can also simplify the installation work of breathing structure, practice thrift the manpower, improve the installation effectiveness.
