DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the utility model proposes a composite exhaust valve, including an exhaust valve housing 1, a flow rate adjustment component and a switch adjustment component: the upper and lower ends of the exhaust valve housing 1 are respectively fixedly connected with an upper exhaust pipe 2 and a lower exhaust pipe 3 through a fixed bracket, and a rubber hose 4 is fixedly connected between the upper exhaust pipe 2 and the lower exhaust pipe 3; the flow rate adjustment component includes two adjusting screws 5 connected to the side wall of the exhaust valve housing 1 through a thread, and the ends of the adjusting screws 5 located outside the exhaust valve housing 1 are fixedly connected with a knob 15, and the ends of each adjusting screw 5 located inside the exhaust valve housing 1 are rotatably connected with an adjusting plate 6, and a limit frame 7 is fixedly connected to the adjusting plate 6, and a transfer plate 8 is slidably connected between the limit frames 7 on the two adjusting plates 6;

[0024] The adjusting plate 6, the limiting frame 7 and the adapter plate 8 can form a limiting cavity, and the rubber hose 4 is located in the limiting cavity. When the adjusting plate and the limiting frame 7 are driven to move, the adapter plate 8 can be synchronously extended or retracted relative to the limiting frame 7 to adjust the limiting space of the limiting cavity. The rubber hose 4 has the characteristics of expansion and contraction, so the diameter size and exhaust flow rate of the rubber hose 4 can be adjusted;

[0025] The adjusting screw 5 is driven to rotate by turning the knob 15, so that the adjusting screw 5 can rotate relative to the exhaust valve housing 1 thread, and then the adjusting screw 5 can push the adjusting plate 6 to move closer to or away from the inner side of the exhaust valve housing 1, so that the limit frame 7 on the adjusting plate 6 moves, and then the adapter plate 8 can be extended and retracted relative to the limit frame 7, and the space size of the limit cavity composed of the adjusting plate 6, the limit frame 7 and the adapter plate 8 can be adjusted, and then the diameter size of the rubber hose 4 can be adjusted. According to the Bernoulli principle, the flow rate of the fluid is not positively correlated with the diameter size of the channel through which it passes. Therefore, the exhaust flow rate in the rubber hose 4 can be adjusted, which is beneficial to alleviate the overall exhaust pressure of the exhaust valve and reduce the use loss of the composite exhaust valve.

[0026] like Figure 1 and Figure 2 As shown, a limit component and a visual adjustment component are provided on the outer wall of the exhaust valve housing 1, the limit component includes a plurality of through holes opened on the exhaust valve housing 1, a limit rod 12 is slidably connected in the through hole, the limit rod 12 is fixedly connected to the adjustment plate 6, the visual adjustment component includes a sliding plate 13 rotatably connected to the end of the adjustment screw 5, a straight rod 14 is fixedly connected to the outer wall of the exhaust valve housing 1, a millimeter-level scale is provided on the straight rod 14, a sliding hole is opened on the sliding plate 13, and the straight rod 14 matches the sliding hole;

[0027] The limiting rod 12 can limit the movement of the adjusting plate 6. At the same time, during the movement of the adjusting plate 6, the sliding plate 13 can move relative to the straight rod 14 with a scale to realize the visualization of the movement of the adjusting plate 6, which is conducive to accurately adjusting the exhaust flow rate inside the composite exhaust valve.

[0028] like Figure 1-Figure 3 As shown, the switch adjustment assembly includes a first discharge plate 9 fixedly connected to the lower end of the lower exhaust pipe 3, the lower end of the outer wall of the lower exhaust pipe 3 is rotatably connected to an annular plate 10 through a bearing, a plurality of paddles 17 are fixedly connected to the outer wall of the annular plate 10, and a second discharge plate 11 is fixedly connected to the inner side of the annular plate 10, the first discharge plate 9 and the second discharge plate 11 are both provided with the same number of exhaust holes 16, and the first discharge plate 9 and the second discharge plate 11 are in contact with each other;

[0029] The annular plate 10 is driven to rotate by toggling a plurality of paddles 17, so that the second discharge plate 11 inside the annular plate 10 is rotated relative to the first discharge plate 9 at a certain angle. When none of the exhaust holes 16 on the second discharge plate 11 corresponds to, i.e., is connected with, the exhaust hole 16 on the first discharge plate 9, the lower exhaust pipe 3 can be completely closed. When the exhaust holes 16 on the second discharge plate 11 completely correspond to the exhaust holes 16 on the first discharge plate 9, the lower exhaust pipe 3 is in a fully open state. At the same time, the exhaust flow rate can be controlled by utilizing the different degrees of correspondence between the exhaust holes 16 on the second discharge plate 11 and the first discharge plate 9, which can effectively improve the applicability of the composite exhaust valve.

[0030] The detailed working process of the utility model is as follows:

[0031] 1. When the composite exhaust valve is used, if it is necessary to reduce the discharge pressure of the lower exhaust pipe 3, the knob 15 can be turned to drive the adjusting screw 5 to rotate, so that the adjusting screw 5 can rotate relative to the exhaust valve housing 1, and then the adjusting screw 5 can be used to push the adjusting plate 6 to move closer to or away from the inner side of the exhaust valve housing 1, so that the limit frame 7 on the adjusting plate 6 moves, and then the adapter plate 8 can be extended and retracted relative to the limit frame 7, and the space size of the limit cavity composed of the adjusting plate 6, the limit frame 7 and the adapter plate 8 can be adjusted, so that the diameter size of the rubber hose 4 can be adjusted. According to the Bernoulli principle, the flow rate of the fluid is not positively correlated with the diameter size of the channel through which it passes. Therefore, the exhaust flow rate in the rubber hose 4 can be adjusted, which is conducive to alleviating the overall exhaust pressure of the exhaust valve and reducing the use loss of the composite exhaust valve;

[0032] 2. If the composite exhaust valve needs to be switched on and off, the annular plate 10 can be driven to rotate by turning a plurality of paddles 17, so that the second discharge plate 11 inside the annular plate 10 rotates relative to the first discharge plate 9 at a certain angle. When none of the exhaust holes 16 on the second discharge plate 11 corresponds to or is connected with the exhaust holes 16 on the first discharge plate 9, the lower exhaust pipe 3 can be completely closed. When the exhaust holes 16 on the second discharge plate 11 completely correspond to the exhaust holes 16 on the first discharge plate 9, the lower exhaust pipe 3 is in a fully open state. At the same time, the exhaust flow rate can be controlled by utilizing the different degrees of correspondence between the exhaust holes 16 on the second discharge plate 11 and the first discharge plate 9, which can effectively improve the applicability of the composite exhaust valve.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
