Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flow guide generating valve, and particularly relates to a chemical agent siphon mixed foam generating valve. BACKGROUND

[0002] In modern life, the Venturi siphon known in the field of dilution of commercial and industrial cleaning liquid is a common mixing tool for chemical liquid and cleaning liquid.

[0003] However, in the application, the traditional T-shaped Venturi siphon can only suck one kind of chemical liquid or cleaning liquid, and after the high-pressure water is introduced into one end, the liquid suction port of the Venturi tube can only suck one kind of chemical liquid, and after mixing and dilution, the mixed liquid is directly sprayed out of the outlet for use. In actual application, two or three kinds of chemical liquid or cleaning liquid are often mixed separately, which increases the trouble of people in actual use, and people have to face the complicated switching of two or three kinds of pipeline at the same time.

[0044] Working principle: The flow guide conversion valve A1 makes clear water enter through the high-pressure clear water connection pipe 8, and plays a role of flow guide and reversing. The flow guide reversing shaft 9 is axially linked with the knob shaft 2. The knob handle 1 penetrates into the knob shaft 2. Moving and rotating the knob handle 1 can be rotated to four positions of RINSE (clear water), FOAM1 (chemical liquid 1), FOAM2 (chemical liquid 2) and FOAM3 (chemical liquid 3) positions. The high-pressure clear water can be guided to the corresponding flow guide hole. When the knob handle 1 is rotated to the RINSE (clear water) position, the high-pressure clear water is guided to the D4 flow guide hole. When the knob handle 1 is rotated to the FOAM1 (chemical liquid 1) position, the high-pressure clear water is guided to the D1 flow guide hole. When the knob handle 1 is rotated to the FOAM2 (chemical liquid 2) position, the high-pressure clear water is guided to the D2 flow guide hole. When the knob handle 1 is rotated to the FOAM3 (chemical liquid 3) position, the high-pressure clear water is guided to the D3 flow guide hole.

[0045] The siphon nozzle fixed body combination A2 is embedded in the middle position of the foam liquid compressed air mixing cavity combination A3.

[0046] When the knob handle 1 is rotated to the RINSE (clear water) position, the high-pressure clear water is guided to the flow guide hole D4.

The one-way valve E cannot enter the compressed air. The high-pressure water is sprayed out through the mixed liquid outlet F on the foam outlet joint 30.

At this time, the water pressure of the mixed liquid passing through the siphon nozzle 14 and the coupler 15 is less than the compressed air. The one-way valve E enters the compressed air into the mixing cavity cover 23. The chemical liquid and the high-pressure clear water mixed liquid are mixed in the mixing cavity cover 23 and sprayed out through the mixed liquid outlet F.
