Water path system of beverage extraction equipment and diverter valve applicable to water path system

Abstract

The invention relates to a water path system of beverage extraction equipment. The system comprises a water tank, a water pump, a boiler, a pressure relief valve and a waste water box; a water outletof the water tank is connected with a water inlet end of the water pump. The system is characterized in that a water outlet end of the water pump is connected with one port of the pressure relief valve; another port of the pressure relief valve is connected with the waste water box, another port of the pressure relief valve is divided into two paths, one path is connected with a cold water inlet end of the boiler through a first one-way valve, and the other path is connected with a water inlet end of an extraction group through a second one-way valve; the first one-way valve only allows waterflow to flow from the pressure relief valve to the boiler, and the second one-way valve only allows the water flow to flow from the water inlet end of the extraction group to the pressure relief valvewhen the pressure is relieved; a hot water outlet end of the boiler is connected with the water inlet end of the extraction group through a third one-way valve, and the third one-way valve only allows hot water to flow to the water inlet end of the extraction group. The hot water in a pipeline cannot be discharged during pressure relief of the water path system, and the route of the hot water entering the extraction group is short. The invention also relates to a diverter valve.

Description

technical field [0001] The invention relates to a waterway system of beverage extraction equipment and a diverter valve suitable for the waterway system, wherein the beverage extraction equipment is an extraction equipment for extracting corresponding liquid from content in a container through high-pressure rapid heating water. Background technique [0002] Beverage extraction equipment is an extraction equipment that extracts the corresponding juice from the contents of the container by high-pressure rapid heating water, suitable for processing containers (capsules) packed with ingredients, and the ingredients are heated with the liquid introduced into the capsule, such as hot Pressurized water interacts to produce a beverage or edible juice. The extraction equipment includes a water tank, a water pump, a heating boiler, and an extraction group. The extraction group includes a first part and a second part that can move relatively. After the second part slides into contact w...

Problems solved by technology

The mechanical pressure relief valve 6' discharges the heated hot water in the heating boiler 3' to the waste water box 8' when the pressure is released, generating more waste water and wasting boiler heating energy; the hot water from the heating boiler 3' needs to pass through the mechanical Type pressure relief valve 6' and then enter the extraction group 7', the flow path of hot water is long, which affects the temperature of the beverage
