Abstract

The utility model discloses a cold-hot water valve connected with tap water pipe or container, with wide application in family, hospital, hotel or the like, to provide cold and hot water, wherein a water outlet of prior water discharge valve is arranged with a tube column 7, inner and outer muffles 9, 10 sheathed outside the column 7, positive and negative power supplies connected with the muffles 9, 10, and a press cover 11 fixed with the ends of the muffles 9, 10. Via the heating electrode composed of the muffles 9, 10, and water resistance, water can be quickly heated in flowing. The utility model has simple and compact structure, novel design, and controllable water temperature under hand operation, reliable property, flexible application, low cost, high benefits, and wide application, as one ideal water discharge valve.

Description

The cold, hot two-purpose water valve

Technical field: the utility model relates to a kind of valve that is connected with water supply pipe terminal or water outlet of container.

Background technique: traditional water valve can only be put cold or hot a kind of water separately, and when putting hot water, must or adopt fire coal, oil-fired boiler that water is heated in the container internal heater.So, not only to expend a large amount of energy, also bring inconvenience simultaneously to use.

Summary of the invention: the utility model mainly is can not put two kinds of water problemss of h and c for a valve that solves the prior art existence, thereby saves the energy, reduces cost convenient the use.

Scheme of the present utility model is as described below: this model utility comprises that by valve body, spool, handle, guard ring, gland, sleeve pipe, screw, switch, wiring terminal it is by establishing pipe stanchion in the water outlet of existing water valve, being enclosed within the fixing gland formation of the sleeve pipe of pipe stanchion outside, the positive-negative power that is connected with sleeve pipe and cannula tip.

The beneficial effects of the utility model: the structure of heating electrode that this model utility owing to taked is made up of the bilayer sleeve that positive-negative power connects and gland, pipe stanchion, seal ring, the combination of other parts in addition, this model utility can not only be emitted water in flowing after the rapid heating, during without hot water, off switch directly provides cold water reliably to realize goal of the invention.And have uniqueness simple and compact for structure, novel, the water temperature manual control is adjustable, performance is safe and reliable, easy to use flexibly, advantage such as cost poor benefit height, market prospects be wide, be suitable for applying.

Description of drawings: Fig. 1 is the overall structure schematic representation of cold, hot two-purpose water valve.

Embodiment: cold, hot two-purpose water valve shown in Figure 1 is to improve a kind of novel water valve that forms on the discharging valve basis that existing valve body 1, spool 2, handle 3, guard ring 4, bolt 5, shell 6 are formed.It is that order is provided with seal ring 8 and pipe stanchion 7 in water outlet side valve body 1 passage, and pipe stanchion 7 is a cavity body by seal ring 8 one sides, is provided with flow channel 18 on the cavity body part.The outside of this pipe stanchion 7 is with inside and outside sleeve pipe 9,10 respectively, and internal and external casing 9,10 two ends are inserted respectively in valve body 1, the gland 11 corresponding set annular grooves.Gland 11 is fixedlyed connected with pipe stanchion 7 through screw 12.DC electrical source is connected with internal and external casing 9,10 respectively with wiring terminal 14,15 through switch 13.On internal and external casing 9,10, also be provided with flow channel 16 and 17.Water inlet of the present utility model and pipeline or container should be connected and fixed during use, when needing hot water, connect positive-negative power, turn handle 3, cold water at first passes seal ring 8 by water inlet through the passage of spool 2, valve body 1 and arrives in pipe stanchions 7 cavity body and enter internal and external casing 9,10 and water outlet by flow channel 18,16,17 then, and under the resistance effect that electrode that internal and external casing 9,10 forms and current produce the cold water rapid heating is flowed out.Only needed just can change the water that flows into 30--70 ℃ hot water 1 second generally speaking, temperature required can the realization by regulating handle 3 change water velocities.It is connected with shower nozzle can be used for shower.Although connecting between the power supply internal and external casing 9,10 under the anhydrous situation still is open-circuit condition, the power supply automatic disconnection.When needing cold water, powered-down, turn handle 3 gets final product.Can realize that so just hot and cold water is dual-purpose.This model utility can be widely used in industries such as family, haircut, hospital, hotel, restaurant.
