Flushing executing mechanism for vacuum closestool

Abstract

A flushing executing mechanism for a vacuum closestool is disclosed by the invention. The flushing executing mechanism is characterized in that the mechanism includes a top cover and an executing mechanism body, a water valve assembly is arranged on the top cover and comprises a valve body, a water inlet and a water outlet are formed in the valve body, a water pipeline is arranged between the water inlet and the water outlet, and a first valve rod is further arranged on the valve body; the first valve rod is provided with a mounting cavity inside, a second valve rod is arranged in the mounting cavity, and a valve head matched with the sealing water pipeline is arranged on the second valve rod; the top cover is further provided with a corrugated rubber film located in the executing mechanism body, a vacuum cavity is formed between the corrugated rubber film and the top cover, the second valve rod is sleeved with a first spring, the corrugated rubber film is sleeved with a driving block for controlling the second valve rod to slide up and down in a sealed mode, and an air channel communicated with the vacuum cavity is formed in the top cover. Through the arrangement, the executing mechanism body is connected with the water valve assembly, the executing mechanism can also achieve the function of a water inlet valve, the occupied space of the whole equipment is reduced, and the application range of the executing mechanism is wider.

Description

technical field [0001] The invention relates to the technical field of vacuum toilets, in particular to a flushing actuator for vacuum toilets. Background technique [0002] The vacuum toilet is to create a vacuum in the whole system. The system must have an isolation valve to isolate the system from each toilet. When the toilet is flushed, the valve is opened, and the contents of the toilet are taken away by the pressure difference with the atmospheric pressure. Ordinary toilets consume 6 liters of water for one flush, but vacuum toilets only need 0.6 liters; it can also separate urine and feces, and the stool can be directly sent to the fertilizer factory to make organic fertilizer. The vacuum system is maintained by the automatic operation of the vacuum pump. Generally, the vacuum toilet is formed by the vacuum pump and the actuator to form a pressure difference with the atmospheric pressure to take away the contents of the toilet. At the same time, the actuator will cont...

Problems solved by technology

The vacuum system is maintained by the automatic operation of the vacuum pump. Generally, the vacuum toilet is formed by the vacuum pump and the actuator to form a pressure difference with the atmospheric pressure to take away the contents of the toilet. At the same time, the actuator will control the opening of the water inlet valve to flush the toilet. It is often used on ships or warships; however, the space on ships or warships is limited, and there are certain restrictions on the volume of vacuum toilets. The existing actuators and water inlet valves are set separately, which increases the volume of the equipment
