Novel heat preservation system of heat preservation tank car

Abstract

The invention relates to a novel heat preservation system of a heat preservation tank car. The novel heat preservation system comprises a tank body heat preservation structure camped between an innertank body and an outer tank body, and a secondary heat preservation structure connected with the tank body heat preservation structure. The novel heat preservation system is technically characterizedin that the secondary heat preservation structure is composed of a tank body end socket secondary heat preservation structure, a tank body V-shaped beam secondary heat preservation structure, a tank body traction disc secondary heat preservation structure and a tank body heat insulation structure located on a tank body metal connector. The novel heat preservation system effectively solves the problem that heat is leaked out of a tank body of an existing heat preservation tank car, heat conduction is effectively blocked, the heat leakage rate is reduced, and therefore the heat preservation effect of the tank body is guaranteed. Meanwhile, on the premise of guaranteeing the heat preservation effect, the weight of the tank body end socket heat preservation structure is reduced, the productiondifficulty is reduced, and production cost is reduced.

Description

technical field [0001] The invention relates to a thermal insulation structure of a closed container such as a tank body, in particular to a novel thermal insulation system for a thermal insulation tank car. Background technique [0002] At present, the thermal insulation structure of the thermal insulation tanker is mainly the tank insulation layer sandwiched between the inner and outer tanks. The tank insulation layer is used to prevent heat loss in the tank. However, the following problems have been found after use: [0003] 1. There is generally a discharge valve under the head of the tank body. In order to achieve the purpose of heat preservation, a valve box is usually provided on the outer cover of the head. In the traditional heat preservation structure, the head and valve box are generally made of carbon steel or stainless steel. In addition, the valve box adopts a fully enclosed structure, that is, the head is completely covered in it. Therefore, the thermal insula...
