Example Embodiment

[0030] The present invention will be further described below through the drawings and specific embodiments.

[0031] The core components of the spiral rotating cylinder to quickly close the high-pressure gas-liquid linkage device are installed on the frame structure 1, such as figure 1 A schematic diagram of the installation of each component is given.

[0032] The upper and lower ends of the frame structure 1 are ring-shaped flanges, and vertical installation ribs are installed between the upper and lower flanges to evenly divide the space between the flanges and also facilitate the installation of various components.

[0033] Among them, the piston type accumulator 2 is installed on the upper flange, the oil pressure gauge 3 and the nitrogen pressure gauge 4 are installed through ribs and are located between the upper and lower flanges, and the pressure switch A5 and the pressure switch B6 are installed under the lower flange On the surface, the oil tank 5 is fixed under the upper ...

Abstract

The invention belongs to a valve control technology, and particularly relates to a high-pressure gas-liquid linkage device for rapidly closing a spiral rotating oil cylinder. The high-pressure gas-liquid linkage device comprises the spiral rotating oil cylinder, a piston type energy accumulator and an oil tank, comprises a stop valve and a logic valve which are mounted on a pipeline of an oil inlet side of the spiral rotating oil cylinder, and further comprises a stop valve and a logic valve which are mounted on a pipeline of an oil outlet side of the spiral rotating oil cylinder; and pipelines between the oil tank and the logic valves communicate with the piston type energy accumulator, the spiral rotating oil cylinder replaces a traditional straight stroke oil cylinder and a shifting fork mechanism, a large-size mechanical transmission structure is omitted, and arrangement of system pipelines is more flexible than that of a mechanical transmission structure. High-pressure nitrogen isused for providing quick-closing energy, a traditional piston type energy accumulator is adopted as an energy storage device, the high-pressure nitrogen can serve as a never-invalid gas spring to replace a traditional mechanical spring, and reliability is higher.

Description

technical field [0001] The invention belongs to valve control technology, in particular to a high-pressure gas-liquid linkage device for fast closing of a helical rotary oil cylinder. Background technique [0002] In some special industries, such as petrochemical and nuclear power, the main circuit valves that need to be driven generally have a large torque (some can reach 100,000 NM) or a large thrust (up to 1,000 KN or more), and they all need to be equipped with fast closing (2-5 Seconds), and in order to prevent malfunction, redundant design is required in the system configuration. [0003] Conventional rotary valve gas-hydraulic linkage actuators generally include a power actuator, a fork actuator box, and an air storage tank or gas-liquid tank. However, conventional gas-hydraulic linkage actuators on the market currently Under the circumstances, due to the relatively low gas supply pressure, the volume is relatively large, the quick closing time is slow, and there is ...
