Improve as one, described filter core is the comminuted steel shot filter core that comminuted steel shot die casting is made.
Improve as one, the first ring connected in star that the upper surface of described filter base is provided with guide ledges and arranges around described guide ledges, described filter core is sleeved in described guide ledges and the lower surface of described filter core and described first ring connected in star offset.
As further improvement, between described filter housing and filter base, be provided with O RunddichtringO.
As further improvement, the sidewall of described filter base upper end is provided with the second annular groove, and described O RunddichtringO is positioned at described second annular groove.
After have employed technique scheme, the beneficial effects of the utility model are: because natural gas engine exhaust gas control valve filtrating equipment arranges filter base at the suction port of exhaust gas control valve, filter core, cap and filter housing on filter core, by the gas-entered passageway of filter housing is connected with the shaping pipeline of suction tude after supercharging, in use, waste gas enters filter core by gas-entered passageway, then exhaust gas control valve is entered through outlet passageway, in the process, dust in waste gas, the assorted dirty impurity that waits will be filtered, thus the air guaranteeing to enter exhaust gas control valve is all clean.The natural gas engine exhaust gas control valve filtrating equipment that the utility model provides solves the fault of dirty stifled, the PWM valve of exhaust gas control valve air inlet screen early mill, thus ensures that suction pressure is adjustable, the normal outputting power of natural gas engine.
Because described filter core is the comminuted steel shot filter core that comminuted steel shot die casting is made, not only have anticorrosive property, and filter precision is higher, the air guaranteeing to enter exhaust gas control valve is further all clean.
Because the upper surface of described filter base is provided with guide ledges, the installation of guide ledges to filter core plays guiding and fixation, is convenient to assembling.
Owing to being provided with O RunddichtringO between described filter housing and filter base, ensure that the sealing between filter housing and filter base by O RunddichtringO, prevent waste gas from leaking.
Because the sidewall of described filter base upper end is provided with the second annular groove, the second annular groove makes the fixing easy of O RunddichtringO.
