Wave-resistant self-pressure-discharging storage tank for petroleum highway-railway transportation

Abstract

The invention discloses a wave-resistant self-pressure-relief storage tank for petroleum highway and railway transportation. The wave-resistant self-pressure-relief storage tank comprises a self-adaptive variable-diameter wave-resistant partition plate, a flame-retardant self-adaptive constant-pressure mechanism, an exhaust cylindrical storage tank assembly and a double-layer external protective shell. The invention belongs to the technical field of petroleum transportation, and particularly relates to an anti-wave self-pressure-discharging storage tank for petroleum highway-railway transportation. The self-adaptive variable-diameter wave-resistant partition plate is creatively provided, when liquid vibrates at a high speed during rapid starting or sudden braking and the like, the liquid impacts the self-adaptive variable-diameter wave-resistant partition plate at a high speed, the variable-diameter valve elastic valve clack can be bent inwards when subjected to high-speed impact, the area of the variable-diameter valve elastic valve clack is reduced, and the self-adaptive variable-diameter wave-resistant partition plate is formed. The amount of liquid passing through the self-adaptive variable-diameter wave-resistant partition plate is reduced; on the basis of an air pressure and hydraulic structure principle, a flame-retardant self-adaptive constant pressure mechanism is creatively provided, the storage volume of internal gas is changed through a lifting type pressure regulating mechanism capable of freely sliding, and the air pressure is reduced by increasing the volume.

Description

technical field [0001] The invention belongs to the technical field of petroleum transportation, in particular to a wave-proof self-draining pressure storage tank for petroleum road and railway transportation. Background technique [0002] Liquid transportation mainly includes road transportation, railway transportation, air transportation, sea transportation, and pipeline transportation. For scenarios where the demand is small, the amount is uncertain, and it is difficult to erect pipelines, the tank trucks used by roads and railways are still the current petroleum The main choice of transportation. [0003] However, the traffic environment is complicated during road transportation. The tank truck is filled with a large amount of fluid liquid (gasoline, diesel, or crude oil). When accelerating or braking suddenly, a large amount of liquid vibrates in the tank, and its strong inertia is very easy. Cause more serious accidents, so most tank trucks on the market are equipped ...

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a constant-pressure anti-vibration barrier for petroleum road and railway transportation that can self-adaptively adjust the mesh size of the anti-wave partition and can automatically balance the air pressure when the flame is roasting. Storage tank; in order to overcome the technical contradiction that the mesh should not be too large (the anti-wave effect is not obvious) nor too small (it is difficult to quickly balance the liquid level of each chamber when it is calm or storing oil), the present invention is based on the principle of insufficient or excessive action Based on the principle of dynamics, the self-adaptive variable-diameter anti-wave baffle is creatively proposed. When the liquid vibrates at high speed, such as fast start or sudden braking, the liquid hits the self-adaptive variable-diameter anti-wave baffle at a high speed. The elastic valve disc of the variable diameter valve will bend inward when subjected to high-speed impact, resulting in the reduction of the area of ​​the elastic valve disc of the variable diameter valve, reducing the amount of liquid passing through the self-adaptive variable diameter anti-wave partition, reducing the mesh and improving The anti-wave effect can reduce the shock of the liquid during rapid acceleration or sudden braking
