A spring damping delay control device for vacuum toilet related equipment

Abstract

The invention relates to a spring damping delay control device used for vacuum toilet related equipment, which includes an input and output unit, an energy unit, a power unit, an execution unit and a control unit; the input and output unit includes a shell and is installed on the shell input interface and output interface, and a control interface for triggering the work of the energy unit and the control unit; the energy unit includes a large flush button assembly and a small flush button assembly; the power unit includes a diaphragm assembly that can realize piston movement The execution unit includes a slide valve assembly connected to the diaphragm assembly; the control unit includes a needle valve assembly and a one-way valve assembly; the present invention adopts a spring-damping delay control device to control, avoiding the gas pressure difference adopted abroad For energy conversion, there is no need for other control methods and energy types such as solenoid valves, batteries, solar energy, and wind energy, and the input cost is low; the structure design is compact, the space occupation rate is small, the types and quantities of parts are small, and the reliability is high.

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...
