Description

technical field

[0001] The invention relates to the technical field of equipment related to vacuum toilets, in particular to a spring damping delay control device for equipment related to vacuum toilets. Background technique

[0002] The basic working principle of the control device is to switch the partial vacuum and atmospheric pressure in the controller chamber alternately, so as to realize the opening (working state) and closing (non-working state) of the vacuum drain valve and the flushing water valve; with this type of structure The control device is used to control the flushing or (and) blowdown process of vacuum toilet related equipment. The control process of the control device is to control the vacuum drain valve so that the feces or other gas-liquid solids in the vacuum toilet are discharged from the vacuum toilet related equipment to the vacuum collection device (such as the intermediate container, the following vacuum waste water tank) or the vacuum sewer At th...
