Abstract

A fuel filter applied to a gas turbine, comprising a filter housing, the filter housing is provided with an inlet manifold and an outlet manifold, and the inlet manifolds are respectively connected to one ends of two shut-off valves installed in the filter housing, the The other end of the stop valve is connected with the bottom end of the filter cartridge, and a filter element is arranged in the filter cartridge, and the upper end of the filter cartridge is connected to one end of the check valve through the filter cover, and the other end of the check valve is connected to the outlet main pipe. There are two components, a filter cover and a check valve, and they are all arranged symmetrically in the filter housing. The present invention solves the problems of existing filter structures such as large volume, poor reliability, high noise during vibration, and no anti-shock vibration design, etc., and satisfies the filtration performance proposed by the gas turbine fuel system, compact structure, online switching and replacement of filter elements, and shock and vibration resistance. , High reliability requirements.

Description

technical field [0001] The invention relates to a fuel filter applied to a gas turbine. Background technique [0002] The existing dual structure of conventional fuel oil filter equipment has the disadvantages of large volume and poor shock and vibration resistance. Gas turbine dual filter equipment has put forward requirements such as compact structure, online switching and replacement of filter elements, shock and vibration resistance, and high reliability. Contents of the invention [0003] The purpose of the present invention is to provide a fuel filter applied to gas turbines, which solves the problems of large volume and poor shock and vibration resistance in the existing conventional double-connected structure of fuel filter equipment. It has a compact structure and can be switched and replaced online. , Shock and vibration resistance, high reliability. [0004] The technical solution adopted to achieve the above purpose is that a fuel filter applied to a gas turbi...
