Preferably, a washer 7 is arranged between the screw 8 and the bracket 11.
The working principle is as follows:
the constituent elements of the waste valve are shown in fig. 1 and 2.
The end cover 1.10 is connected with the upper support 1.7 through a first screw 1.11, one end of the spring 1.9 is connected to the end cover, the other end of the spring is connected to the spring seat 1.8, the spring seat is connected with the lower support 1.6, and the lower support is connected to the second rubber sleeve 1.5. The first rubber sleeve 1.1, the end cover 1.10, the housing 1.4, the lower bracket 1.6 and the second rubber sleeve 1.5 together form a sealed cavity 12.

Fig. 3 shows the stand-by state of the waste valve. The cavity 12 is in a normal pressure state, the lower support 1.6 and the upper support 1.7 move oppositely under the action of the elastic force of the spring 1.9 to extrude the rubber pipe 1.3, and meanwhile, because the sewage discharge port side of the rubber pipe is in a vacuum environment, the rubber pipe 1.3 is in an extruded and sealed state under the double actions of the elastic force of the spring and the air pressure difference, and the sewage discharge valve is closed.
Fig. 4 shows the operation state of the waste valve. After the flushing process of the vacuum toilet system is activated, vacuum is provided to the blow-down valve through the vacuum interface 1.2, and the cavity 12 is converted into a vacuum state. The first rubber sleeve 1.1 and the second rubber sleeve 1.5 are extruded towards the inside of the cavity under the action of the air pressure difference, when acting force generated by the air pressure difference is larger than elastic force of the spring 1.9, the first rubber sleeve 1.1 pushes the end cover 1.10 and the upper support 1.7 to move downwards, the rubber sleeve 2 pushes the lower support 1.6 to move upwards, the extruding force acting on the rubber pipe is gradually eliminated, the rubber pipe is restored to a free state (as shown in figure 5), the blow-down valve is opened, and dirt in the toilet bowl is discharged into the vacuum dirt box under the vacuum action. Because the sewage inlet side of the rubber tube 1.3 is in a normal pressure state, the acting force generated by the air pressure difference and the self-recovered elastic force of the rubber tube 1.3 are also helpful for opening the sewage discharge valve to a certain extent. After the sewage discharge is finished, normal pressure atmosphere is provided for the sewage discharge valve through the vacuum interface 1.2, and the sewage discharge valve is gradually restored to a standby state. The vacuum connection 1.2 can be connected to a reversing valve or controller, so that the atmosphere and the vacuum source can be connected separately.
In some embodiments, besides the vacuum interface 1.2, the waste discharge valve is also provided with a normal pressure interface specially used for connecting the atmosphere, and the normal pressure interface is used for providing the normal pressure atmosphere for the waste discharge valve after the waste discharge is finished. The normal pressure interface can be switched on and off.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not necessarily depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
