Abstract
A coffee machine waterway constant flow and constant pressure valve comprises a valve body. The valve body is sleeved with a membrane. A water chamber cavity is formed between the valve body and the membrane. A water inlet hole and a water outlet hole are formed in the valve body. The two ends of the valve body are connected with a valve deck and a valve bushing respectively. A pipeline is arranged inside the valve body. The valve deck is connected with the valve bushing in a fastened mode. An air chamber cavity is formed between the valve deck and the membrane. When an electromagnetic pump works, water flows into the water chamber cavity through a pipeline from the water inlet hole, and the membrane will generate response deformation along with work of the electromagnetic pump. Water is buffered and energy is stored inside the water chamber cavity, the flow and pressure of the pipeline are kept constant to be invariable, and then the water enters the pipeline of the valve deck through the water outlet hole and flows into a follow-up waterway system through a joint of the valve bushing. Noise generated in the overall water pumping process is quite small, the flow and pressure of the waterway are kept constant to be invariable, and the extracted espresso quality is quite high.
