The front support of the inner liner of the horizontal vehicle-mounted liquefied natural gas storage tank

Abstract

The invention provides a front support of a liner of a horizontal vehicle-mounted liquefied natural gas storage tank, belonging to the mechanical technology field of pressure containers. With the key technology that a non-metal composite supporting tube is arranged between the liner and a shell, the front support is characterized in that a shell front head is welded together with a liner front head; a center hole of the shell front head is welded together with the excircle of a supporting flange; the center hole of the liner front head is welded together with the excircle of a front end support shaft hub; the rear end of the supporting flange is welded together with the front end of supporting U steel; the rear end of the supporting U steel is welded together with the front end of the front end support shaft hub; the rear end of the front end support shaft hub is welded together with the front end of a casing; the supporting flange and the front end section of a composite supporting tube A are fixed by a pin A; the rear end section of the composite supporting tube A and the front end support shaft hub are fixed by a pin B; the composite supporting tube A is inlaid in a composite supporting tube B; the composite supporting tube B is inlaid in a liquid filling tube; the front end section of the liquid filling tube and a liquid filling flange are fixed; and the rear end of the liquid filling flange and the front end of the supporting flange are fixed. The front support is used for fixing the liner and shell of the storage tank, has good fixing effects and effectively reduces heat losses.

Description

technical field [0001] The present invention relates to the front support of the liner of a horizontal vehicle-mounted liquefied natural gas storage tank, and relates to the field of mechanical technology; in particular, it relates to the field of mechanical technology of pressure vessels; in particular, it relates to the field of mechanical technology of the liner of a vehicle-mounted liquefied natural gas storage tank; in particular, it relates to the field of horizontal vehicle-mounted liquefaction The technical field of the front support of the inner liner of the natural gas storage tank. Background technique [0002] Horizontal vehicle-mounted liquefied natural gas storage tanks mainly store liquefied natural gas at a temperature of -162°C. In order to keep warm, this type of storage tank is composed of two parts: an inner tank and an outer shell. There is a vacuum interlayer between the inner tank and the outer shell. There is a structure to prevent heat radiation and ...
