Hydraulic tightening and compressing type pressure vessel emergent plugging device

Abstract

The invention relates to a hydraulic tightening and compressing type pressure vessel emergent plugging device. A hydraulic tightening device is connected with a hydraulic portable fire pump through a first hydraulic oil circuit; a hydraulic plugger is connected with the hydraulic portable fire pump through a second hydraulic oil circuit; one-way valves are arranged on the first hydraulic oil circuit and the second hydraulic oil circuit; a tightening connecting rod assembly is of a parallelogram structure with vertex parts being hinged; two ends of the hydraulic tightening device are connected with one pair of vertexes of the tightening connecting rod assembly; the other pair of vertexes of the tightening connecting rod ass are connected with two ends of a binding lock; a plugging base is connected onto the binding lock; an ejector rod hole for a hydraulic ejector rod to stretch into is formed in the middle of the plugging base; a plurality of air discharge holes are formed in positions, close to the bottom part of the plugging base, on the periphery of a hole wall of the ejector rod hole; and a plugging press block is arranged at the head part of the hydraulic plugger. The hydraulic tightening and compressing type pressure vessel emergent plugging device provided by the invention is convenient to operate and large in binding and plugging compression force, and cannot be influenced by leaked injection pressure during a plugging process, so that a plugging tool cannot be slipped.

Description

Technical field [0001] The invention relates to an emergency leak plugging device for a pressure container, in particular to a hydraulic tightening and compression type emergency leak plugging device for a pressure container, belonging to the technical field of leak stoppers. Background technique [0002] Pressurized containers are often used to store flammable, explosive, and toxic liquids or gases. Therefore, once a leak occurs, it will cause serious injuries and huge losses to people's lives and property. For leaking accidents of pressure vessels, bundling, casing, and sticking plugging tools can be used for emergency plugging. However, the existing leakage plugging tools are generally tightened manually or pneumatically, which results in insufficient tightening force and cannot effectively seal leaks with high pressure such as tank trucks, oil storage tanks, and oil pipelines. In addition, in the emergency plugging process, the plugging block of the existing plugging tool is...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is: in the emergency plugging process, the tightening force of the existing plugging tools is not large enough to effectively plug the leaks with high pressure such as tank trucks, oil storage tanks, and oil pipelines; at the same time, plugging When the leak block is sealing the leakage port, it is easy to slip, resulting in inaccurate plugging positioning and poor plugging effect
