Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following mode of execution.
As shown in Figure 1-2, a kind of valve mechanism of steam whistle, comprise valve rod 1, lining 2, valve body 3, gland cap 5, sealing lining 4, through hole is provided with in described valve body 3, inlet hole 3-2 is provided with in the side of through hole, air outlet hole 3-1 is provided with at the opposite side of through hole, sealing lining 4 is fixed on one end of valve body 3 through hole by screw thread, through hole is provided with in sealing lining 4, at air outlet hole 3-1 place, position between air outlet hole 3-1 and inlet hole 3-2 is provided with lining 2, lining 2 is fixed on valve body 3 by screw thread, through hole is provided with in lining 2, valve rod 1 is arranged in the through hole in sealing lining 4 and lining 2, gland cap 5 is fixed on the other end of valve body 3 through hole by screw thread.
Lining 2 is provided with 4-8 bush hole 2-1, and one end of lining 2 is provided with protruding outer 2-2, and the port being provided with one end, outer is fallen as inclined-plane.
Bush hole 2-1 is arranged on lining 2 a week of air outlet hole 3-1 place.
Lining 2 adopts teflon to make, and the outer 2-2 of lining 2 is close to the recess that valve body 3 inner via hole coordinates with it, is tightly shut by air flue.
Valve rod 1 comprises pull bar 1-1, drive link 1-2, taper blocks 1-3, spring 1-5, foot piece 1-4, drive link 1-2 is arranged on one end that pull bar 1-1 stretches into valve body 3, the other end of drive link 1-2 is provided with taper and blocks 1-3, the other end blocking 1-3 in taper arranges foot piece 1-4, foot piece 1-4 stretches in the groove of gland cap 5, and spring 1-5 is socketed on foot piece.
Be provided with two circular grooves that size diameter is different in gland cap 5, large diameter groove is used for leaving installing space for spring 1-5, and the groove of minor diameter, for inserting foot piece 1-4, for foot piece 1-4 leaves activity space, plays motion guide simultaneously.
The diameter of drive link 1-2 is less than the diameter of pull bar 1-1, leaves certain space between drive link 1-2 and lining 2.
One end of spring 1-5 is withstood taper and is blocked 1-3, and the other end withstands gland cap 5.
See Fig. 1, when not starting steam whistle, spring 1-5 is in extended configuration, and taper blocks 1-3 under the effect of spring 1-5, withstands lining 2.The port being provided with one end, outer due to lining 2 is fallen as inclined-plane, and therefore taper blocks the cone inclined-plane of 1-3 and fits tightly with lining 2, is tightly shut by the air inlet position of valve body 3 inner via hole.
See Fig. 2, when needs start steam whistle, the controlling rod of steam whistle valve mechanism is located in driver's cab, pulls with hand controlling rod, and the valve rod 1 that can promote in valve body 3 device moves inwards, spring 1-5 is in compressive state, taper blocks 1-3 and leaves lining 2, and steam enters the through hole in valve body 3 by inlet hole 3-2, and leads to air outlet hole 3-1 by the bush hole 2-1 on the space between drive link 1-2 and lining 2 and lining 2, spray in device above, thus send loud sound of blowing a whistle.
