Non-electric pure mechanical control logic actuator of vacuum toilet

Abstract

The invention discloses a non-electric pure mechanical control logic actuator of a vacuum toilet stool, which comprises a pneumatic valve assembly used for controlling the on-off of a gas circuit between the toilet stool and a sewage tank; the vacuum tank is used for performing vacuum compensation on the sewage tank; the first pressure tank is used for providing a power source for the pneumatic valve assembly; the second pressure tank is used for inputting gas into the sewage tank; the sewage discharge pipeline is used for discharging sewage in the sewage tank; the first pressure tank controls on-off of an air channel through the pneumatic valve assembly, so that the vacuum tank conducts vacuum compensation on the sewage tank, sewage in the toilet bowl is pumped into the sewage tank, then the second pressure tank inflates the sewage tank, the sewage tank is pressurized and then discharged through the sewage discharging pipeline, and automatic flushing and drainage of the toilet bowl are achieved. According to the invention, secondary flushing of the toilet stool can be realized, environmental influences such as humidity and temperature are reduced by adopting pneumatic control, the manufacturing cost and the maintenance cost of the actuator can be reduced, and the practicability is high.

Description

technical field [0001] The invention relates to a non-electric purely mechanical control logic actuator for a vacuum toilet. Background technique [0002] With the continuous development of society, vacuum drainage technology has been widely used in railways, buildings, ships, aircraft, municipal and other occasions. Vacuum drainage technology has the characteristics of water saving, sanitation, small pipe diameter and flexible layout. [0003] However, the vacuum toilets in the prior art are generally controlled by electric control valves. Although the control accuracy is high, it is easy to cause loss of electric energy. Certain potential safety hazards, and high manufacturing and maintenance costs. Contents of the invention [0004] The purpose of the present invention is to provide a technical solution for the non-electric purely mechanical control logic actuator of the vacuum toilet, which can not only realize the secondary flushing of the toilet, but also adopt pne...
