Technical field
The utility model relates to a kind of metering pump, relates in particular to a kind of measuring jet structure that is used for the vehicle exhaust processing system of tool holding cavity.
Background technique
Selective catalytic reduction system operating SCR(Selective Catalyst Reduction) is a processing system to downstream working medium, its principle is exactly to spray into ammonia in containing the tail gas of NOx, urea or other nitrogen-containing compound, make NOx wherein be reduced into N2 and water, be used at present in the diesel engine vent gas processing procedure.
Selective catalytic reduction system operating SCR must accurately control and spray into ammonia, the straying quatity of urea or other nitrogen-containing compound, in order to remove to greatest extent NOx, therefore metering pump becomes the requisite constituent element of selective catalytic reduction system operating SCR, and nozzle especially metering pump be used for control spray into the ammonia amount vitals.
See also shown in Figure 1, Fig. 1 is the structural representation of the nozzle of traditional metering pump that is used for the vehicle exhaust processing system, traditional metering pump nozzle comprises nozzle valve seat 10 and the nozzle spool 11 that is arranged in the nozzle valve seat 10, offer hydrojet import 12 and hydrojet outlet 13 on the described nozzle valve seat 10, one end of described nozzle spool 11 connects electromagnet, described electromagnet is by electromagnetic valve components 14 control adhesive or separation, be provided with the seat surface sealing configuration between described nozzle valve seat 10 and the nozzle spool 11, when the solenoid valve outage, nozzle spool 11 is under the effect of spring force, spool head seat surface and valve seat bottom seat surface are adjacent to sealing, and nozzle is hydrojet not; And when the solenoid valve energising, electromagnetic force overcomes spring force will be carried on the nozzle spool 11, and hydrojet is from hydrojet outlet 13 ejections; Solenoid valve cuts off the power supply again, repeats said process.
But the nozzle valve seat 10 of above-mentioned measuring jet and nozzle spool 11 all adopt stainless steel to make, and cost is higher, and are not easy to processing.
