Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify setting formula of the present utility model and decide the air quantity valve.
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the left side view of Fig. 1, wherein, looks into for the ease of sight, has removed the side plate on valve body right side among Fig. 1; Fig. 3 is the structural representation of the utility model cam; Fig. 4 is the structural representation of valve film pilot port in the utility model; Fig. 5 is the plan view of Fig. 4.
As shown in Figure 1 and Figure 2, setting formula of the present utility model is decided the air quantity valve, includes the perforation valve body 14 that is used for wind-guiding, is provided with axle 1 in valve body 14, and two side plates 16,17 of valve body 14 are stretched out at its two ends of 1; Be set with blade 4 on the axle 1 of valve body 14 inboards, blade 4 is provided with air bag 3, and the gas port of air bag 3 is fixed on the blade 4 that is formed with fixed hole by valve film pilot port 5.The structure of its valve film pilot port 5 such as Fig. 4, shown in Figure 5 are to be made of chassis 18 and integrally formed thereon convex mouth 19.Wherein, chassis 18 is installed in the inboard of air bag 3, and convex mouth 19 is installed in the outside of air bag 3, and is fixed on the fixed hole of blade 4.Be formed with the gas port of one or more connection valve film pilot port 5 on the air bag 3.Valve body 14 inboards be positioned at air bag 3 above also fixedly install the baffle plate 2 that restricted air bag 3 rose in when inflation.The two ends of baffle plate 2 are fixedly connected on the inboard of two side plates 16,17 of valve body 14, and present embodiment is with the two ends riveting of baffle plate 2 inboard at two side plates 16,17 of valve body 14.
Be set with an end of positioning plate 6 on a termination that is positioned at valve body 14 outsides of axle 1, the other end of positioning plate 6 connects an end of the pull bar 13 that is arranged on valve body 14 outsides equally by pull bar link 7, and the other end of pull bar 13 connects shell fragment 12; On the outer side surface of the side plate 17 that axle 1 valve body that stretches out 14 is arranged, be set with cam fixed tray 8, be set with adjusting axle 10 on the cam fixed tray 8, be connected with the cam 11 that links to each other with the other end of shell fragment 12 and control shell fragment 12 degree of crook on the adjusting axle 10.Between cam fixed tray 8 and cam 9, also be provided with nylon washer 9 on the adjusting axle 10.
