Improve as one, described metal mufflers comprises metal tube, and described metal tube one end is connected on the exhaust end of described exhaust gas control valve, and the other end is provided with relief opening.
After have employed technique scheme, the beneficial effects of the utility model are: because natural gas engine new waste gas control valve assembly arranges filter base at the inlet end of exhaust gas control valve, filter core, cap and filter housing on filter core, the outlet side of exhaust gas control valve is provided with metal mufflers, when air displacement is excessive, 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, then waste gas is discharged from the outlet side of exhaust gas control valve through metal mufflers, because baffler adopts metal mufflers, instead of the baffler of existing use sand copper powder die casting structure, solve sand copper powder baffler and expose for a long time in atmosphere easily by the dirty stifled problem of dust.The natural gas engine new waste gas control valve assembly that the utility model provides can solve the inner dirty stifled and dirty stifled problem of exhaust end baffler of exhaust gas control valve, can reduce the rate of fault of exhaust gas control valve greatly, effectively increases product working life.
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.
