Anti-overflow device for vertical low-temperature storage tank

Abstract

The invention discloses an anti-overflow device for a vertical low-temperature storage tank. The anti-overflow device comprises a tank body, an inner overflow pipe, an outer overflow pipe, a fullnessmeasuring valve, a T-junction, a sleeve tee, a test pipe and a diffusing pipe. An overflow port is formed in the center of the top of the tank body, the overflow port is provided with a connecting block, one end of the inner overflow pipe is fixed at the bottom of the connecting block and the other end of the inner overflow pipe extends to the inside of the tank body. The outer overflow pipe is L-shaped, one end of the outer overflow pipe is fixed on the side of the connecting block, the other end of the outer overflow pipe extends to the side portion of the tank body, and the outer overflow pipe and the inner overflow pipe communicate with each other inside the connecting block. The fullness measuring valve is fixed at the middle part of the outer overflow pipe. The sleeve tee is fixed atthe end of the outer overflow pipe, the sleeve tee is connected with one end of the diffusing pipe, the other end of the diffusing pipe extends upwards, and an elbow is arranged at the other end of the diffusing pipe. The anti-overflow device for the vertical low-temperature storage tank can effectively prevent the occurrence of overcharging phenomenon, saves filling materials and can ensure thepersonal safety of workers.

Description

technical field [0001] The invention relates to an anti-overflow device, in particular to an anti-overflow device for a vertical low-temperature storage tank, and belongs to the technical field of low-temperature container equipment. Background technique [0002] During the filling process of the vertical low-temperature storage tank using the differential pressure method, because the storage tank is opaque, it is difficult for the operator to grasp the liquid capacity in the tank, so overfilling will occur for a long time, which not only wastes the filling materials, but also If the material is a flammable or corrosive liquid, it is extremely dangerous, so it is necessary to design an anti-overflow device for a vertical cryogenic storage tank. Contents of the invention [0003] The object of the present invention is to provide an anti-overflow device for a vertical low-temperature storage tank, which can prevent the occurrence of overfilling and solve the above-mentioned ...
