Problems solved by technology

[0003] There are many high-quality control valves (such as DN50 and DN40 pneumatic valves) in the piping system of LNG fuel tanks and GVU valve-controlled boxes. When the ship’s hull shakes greatly on the sea or on the river, the control valves may It will be damaged because it cannot be fixed, resulting in the leakage of natural gas

Abstract

The invention provides a gas supply system of an LNG fuel power ship. The gas supply system of the LNG fuel power ship comprises an LNG fuel tank, a gasifier connected with the LNG fuel tank and a GVUvalve control box connected with the gasifier. A plurality of control valves are arranged in a pipeline system of the LNG fuel tank and the GVU valve control box. The gas supply system further comprises a valve supporting device for fixing the control valves. After LNG in the LNG fuel tank is gasified into natural gas through the gasifier, gas is supplied to an engine in a cabin through the GVU valve control box, and power is provided for the ship. The valve supporting device is used for fixing the control valves. A supporting rod assembly, a supporting block and a connector achieve a certaindegree of freedom through rotation. Meanwhile, the supporting rod assembly has the axial and radial buffering function, vibration generated by shaking of a ship body can be buffered while the controlvalves are fixed, and the valve supporting device can be effectively prevented from being broken. The supporting rod assembly is telescopic, and the work length of the valve supporting device can beadjusted according to the distance between the control valves and a fixing support.

Description

technical field [0001] The invention belongs to the technical field of LNG fuel-powered ships, and in particular relates to a gas supply system for LNG fuel-powered ships. Background technique [0002] LNG fueled ships refer to ships whose engines use natural gas and diesel as dual fuels or ships whose engines use natural gas as a single fuel. The LNG fuel-powered ship gas supply system includes an LNG fuel tank, a gasifier connected to the LNG fuel tank, and a GVU valve control box connected to the gasifier. After the LNG in the LNG fuel tank is gasified into natural gas by the gasifier, Air is supplied to the engine in the engine room through the GVU valve control box to provide power for the ship. [0003] There are many high-quality control valves (such as DN50 and DN40 pneumatic valves) in the piping system of LNG fuel tanks and GVU valve-controlled boxes. When the ship’s hull shakes greatly on the sea or on the river, the control valves may It will be damaged because...
