Embodiment
Technical scheme of the present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment 1
Refer to the regulator of a kind of PEM fuel cell engine air system shown in Fig. 1, Fig. 2, comprise valve body 1, one end of valve body 1 is provided with first passage, and the other end is provided with end cap 5; Second channel is provided with in end cap 5, first passage with axis and the dead in line of second channel, spool 3 and transmission mechanism 4 is also provided with in valve body 5, the inner of spool 3 is stretched in first passage from the inner of first passage, the output of transmission mechanism 4 is connected with the outer end of spool 3, is also installed with the sealing gasket 2 of the outer end for the inner and spool sealing first passage outside the inner of first passage.
Spool in Fig. 1, Fig. 2 adopts cylindrical structural, the square air vent hole of the side arrangement of cylindrical spool; Valve body 1 and spool 3 junction increase sealing gasket 2; Spool 3 drives reciprocating motion in valve body 1 by transmission mechanism 4, and by transmission mechanism 4 and valve body 1 complete guiding and spacing; Transmission mechanism 4 is bar linkage structure, is driven by motor reducer, the optional stepper motor of motor or DC servo motor.
Like this when shutdown (closedown) operating mode as shown in Figure 1, adjusting device of the present invention is locking state, and the sealing gasket 2 between valve body 1 and spool 3 keeps certain pretightning force, relies on sealing gasket 2 to seal whole air road.When operating condition as shown in Figure 2, motor drive transmission device 4 moves, traction spool 3 moves horizontally, and effective actual internal area on whole air road changes along with the movement of spool 3, thus meets the different operating condition of fuel battery engines to operating pressure and traffic requirement.
