Abstract

The utility model discloses a mixed cold and hot fluid jet device. A water outlet pipe of a plug valve is connected with one end of a cold water inlet pipe of the fluid jet device into a whole through a connecting pipe. The other end of the cold water inlet pipe is provided with a suction chamber of which the inner cavity is provided with a nozzle. A hot water inlet pipe is arranged on the upper side of the suction chamber. The ratio of the diameter of the hot water inlet pipe to the diameter of the small hole of the nozzle is 1: 4-1: 6. The lower ends of the suction chamber and the nozzle are provided with throat entrance sections of which the lower ends are also provided with throats. The lower ends of the throats are provided with diffusion pipes. The utility model has the advantages of large water outlet pressure and good jet effect, and the cold and hot fluid is uniformly mixed in proportion of 1: 1. The mixed cold and hot fluid jet device is especially suitable for cold and hot fluid using systems in domestic electric-heating showers, bathrooms and kitchen facilities.

Description

Cold fluid and hot fluid mixing jet device

The utility model belongs to a kind of cold fluid and hot fluid mixing jet device that is used for domestic electric heating shower and toilet kitchen utilities.

Regulating at present mixing hot and cold water in the domestic electric heating shower is to adopt plug valve, is drilled with aperture in the cock of plug valve, can only play the role of changing, and therefore exists discharge pressure low, and no ejection function, hot and cold water such as can not mix in proportion at weak point.

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of discharge pressure big, and jeting effect is good, cold fluid and hot fluid (liquids and gases) in proportion with temperature required mixed uniformly cold fluid and hot fluid mixing jet device.

The purpose of this utility model is to realize like this, the outlet pipe of plug valve is connected as a single entity by cold water inlet one end of tube connector and fluidic device, the cold water inlet other end is established suction chamber, the suction chamber inner chamber is established nozzle, the suction chamber upside is established the hot water inlet pipe, and hot water inlet pipe's diameter is 1: 4～1: 6 with nozzle hole diameter ratio, and the trunnion entrance is established in suction chamber and nozzle lower end, trunnion is established in trunnion entrance lower end, and anemostat is established in the trunnion lower end.

The utility model can make that cold water and hot water evenly mix in 1: 1 ratio in domestic electric heating shower and toilet, the kitchen utilities, and its leaving water temperature remains constant temperature, and discharge pressure and flow increase, and be spurting, and the capacity of storage tank is doubled.

Below in conjunction with drawings and Examples the technical solution of the utility model is described.

Fig. 1 is a structural representation of the present utility model.

With reference to Fig. 1, the utility model is made up of plug valve 1 and fluidic device 9.Plug valve 1 is three two and leads to that can be controlled in rotation (+90 °～0 °～-90 °) in 180 °, three positions are respectively water inlet pipe 17, outlet pipe 2, outlet pipe 18.Water inlet pipe 17 is connected with running water pipe, outlet pipe 2 is to be connected with storage tank one end, outlet pipe 18 is connected as a single entity by the cold water inlet 10 of tube connector 3 with fluidic device 9, tube connector 3 can adopt the flared type tube connector, outlet pipe 18 also can be by nut 4 ' link to each other with tube connector 3 one ends, and tube connector 3 other ends are linked to each other with fittings body 5 by nut 4; Fittings body 5 links to each other with cold water inlet 10 1 ends of fluidic device 9, establish shape sealing ring 7 and pad 6 between fittings body 5 and fluidic device 9, the cold water inlet 10, cold water inlet 10 other ends are provided with suction chamber 12, suction chamber 12 inner chambers are established nozzle 8, its upside is provided with hot water inlet pipe 11, the tapering of nozzle 8 (endoporus) is 1: 5, and hot water inlet pipe's 11 diameters are 1: 4～1: 6 with the diameter ratio of nozzle aperture 16; Suction chamber 12 lower ends are provided with conical trunnion entrance 13, and columniform trunnion 14 is established in trunnion entrance 13 lower ends, and trunnion 14 lower ends are provided with tubaeform anemostat 15, and the tapering of anemostat 15 is 1: 7.Hot water inlet pipe's 11 other ends are connected with the storage tank other end.

Its course of work: plug valve is threaded to-90 ° earlier, water inlet pipe 17 is by outlet pipe 2 water filling in storage tank, after water is filled with plug valve 1 is threaded to+90 °, cold water in the storage tank is by electric heater heating (can be heated to 70 °～80 ℃ during shower), plug valve 1 is threaded to 0 °, water inlet pipe 17 is communicated with outlet pipe 18, cold water enters nozzle 8 by tube connector 3, cold water inlet 10, hot water in the storage tank enters suction chamber 12 by hot water inlet pipe 11, hot water and cold water are ejected by anemostat 15 by trunnion 14 after mixing in trunnion entrance 13.
