Abstract

The invention discloses a pure mechanical pneumatic control logic actuator of a vacuum toilet stool, comprising a first pneumatic stop valve which is connected with the toilet stool and a sewage tank; the second pneumatic stop valve is connected with the sewage tank and the sewage discharge pipeline; the pneumatic valve assembly comprises a vacuum tank, a first pressure tank and a second pressure tank; the first pressure tank controls the first pneumatic stop valve and the second pneumatic stop valve through the pneumatic valve assembly, and the suction rate and the discharge rate of the sewage tank are adjusted. According to the device, the opening or closing speed of the first pneumatic stop valve and the second pneumatic stop valve can be increased, noise of the toilet in the suction and pollution discharge process can be reduced, the effect that airflow washes the inner wall of a flow channel can be achieved, the risk of dirt adhesion and clamping is prevented, the pollution discharge efficiency is improved, and the service life of the toilet is prolonged. Meanwhile, sewage and air in the sewage tank cannot flow backwards through the first pneumatic stop valve.

Description

technical field [0001] The invention relates to a pure mechanical pneumatic control logic actuator for a vacuum toilet. Background technique [0002] Vacuum toilets have good water-saving performance and sewage discharge performance, and are widely used in airplanes, trains, ships, public toilets, etc., but the vacuum toilets are noisy during use. There are two main sources of noise in vacuum toilets: on the one hand, the noise generated by the friction and collision of sewage in the sewage pipe; The high-speed air formed at the sewage outlet, the flushing water and the friction and vibration of the sewage outlet produce noise. The noise generated in the sewage pipeline can be eliminated by wrapping and isolating, but the noise generated at the sewage outlet cannot be eliminated structurally with a muffler. Contents of the invention [0003] The purpose of the present invention is to provide a purely mechanical and pneumatic control logic actuator technical solution for ...
