Rear support of liner of horizontal vehicle-mounted liquefied natural gas storage tank

Abstract

The invention provides a rear 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 rear support is characterized in that the outer end section of a liner rear support sleeve is inserted into a center hole of a liner rear head and is welded, and the inner end of the liner rear support sleeve is welded together with a linear rear supporting base; the outer end of a rear supporting seat is welded together with an outer liner rear head; and the inner end section of the composite supporting tube is inserted into the liner rear support sleeve and is fixedly connected with the liner rear support sleeve by a pin, and the outer end section of the composite supporting tube is inserted into the rear supporting seat and is movably connected with the rear supporting seat in a sliding manner. The rear support is used for fixing the liner and shell of the storage tank, has good fixing effects, avoids damages to rear supporting assemblies due to axial deformation of the liner cylinder, and effectively reduces heat losses.

Description

technical field [0001] The invention relates to the rear support of the liner of a horizontal vehicle-mounted liquefied natural gas storage tank, which 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 rear 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 reduce h...
