Description
Technical field
The utility model relates to domestic drinking water equipment part field, is a kind of family expenses instant heating type drinking device combination valve that guarantees hydraulic pressure, avoids jet phenomenon specifically.
Background technology
At present household drinking water is main with boiling water generally, and the mode that boils water has two kinds of electric kettle and hot type water dispensers usually.The instant heating type drinking device is the drinking water heating products of releasing in recent years, and it adopts the mode of Fast Heating boiled cold water, and the user can obtain drinking hot water fast, so receive consumers in general's favor deeply.Yet the instant heating type drinking device itself exists a great technological deficiency, owing to can produce water vapour in the boiled process of hot water, water vapour can be infiltrated in the hot water when hot water supply.The existence of water vapour jet phenomenon intermittently also can occur, the human body of burning easily except meeting makes the hydraulic pressure instability of instant heating type drinking device when supplying water.What the instant heating type drinking device was taked is the mode of heating of quick-heating type, and the generation of water vapour and jet influence are especially serious, does not improve above-mentioned shortcoming and have efficient ways in the prior art.Therefore, instant heating type drinking device structure still remains further to be improved at present.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of stable water pressure, safe and reliable family expenses instant heating type drinking device combination valve are provided.
The goal of the invention of the utility model is achieved in that a kind of family expenses instant heating type drinking device combination valve; It is characterized in that: said combination valve comprises pressure valve that two ends are communicated with water inlet pipe and outlet pipe respectively and the back-water valve (BWV) that is communicated with water inlet pipe, and the water side of back-water valve (BWV) is communicated with the water fountain water tank.
Said pressure valve comprises valve body, be located at the spool in the valve body and be located at valve body and spool between spring.
Said back-water valve (BWV) comprises valve body and the spool that is located in the valve body.
Said water inlet pipe is provided with three-way pipe, and three-way pipe is communicated with water fountain water tank, pressure valve water inlet end and back-water valve (BWV) water inlet end respectively.
The water side of said back-water valve (BWV) is provided with the back pressure pipe, and the back pressure pipe is communicated with the water fountain water tank.
The water side of said back-water valve (BWV) is provided with three-way pipe, and three-way pipe is communicated with back-water valve (BWV), water fountain water tank and back pressure pipe respectively.
The utility model improves the family expenses instant heating type drinking device of prior art, on the water supply water route of water fountain, pressure valve is set, this pressure valve comprises valve body, be located at the spool in the valve body and be located at valve body and spool between spring.Through the inspection pressure and the pressure limiting effect of pressure valve, make the current of band water vapour can not back down spool entering water side, effectively avoided jet phenomenon, improved the security that water fountain uses greatly.And the current of band water vapour get into the backwater end through backing down the backwater spool, and are back to the heating that circulates of water fountain water tank.When the current of pressure valve water side when moisture vapor and pressure do not meet the requirements, current back down spool and get into the water side, and the back pressure pipe is then exported the current back pressure, makes hot water can not flow to back-water valve (BWV), guarantees the stability of drinking water water outlet.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
Shown in accompanying drawing 1, the family expenses instant heating type drinking device combination valve of the utility model mainly comprises pressure valve 1 and back-water valve (BWV) 2.Wherein the water inlet end of pressure valve 1 and water side are communicated with water inlet pipe and outlet pipe respectively; The water inlet end of back-water valve (BWV) 2 then is communicated with water inlet pipe, and its water side is communicated with water-heater water tank.Pressure valve 1 comprises valve body 11, spool 12 and spring 13, and wherein spool 12 is arranged in the valve body 11, and 13 on spring is arranged between valve body 11 and the spool 12, and the difference roof pressure is on valve body 11 and spool 12.2 of back-water valve (BWV)s comprise valve body 21 and spool 22, and spool 22 is arranged in the valve body 21.Water inlet pipe is provided with three-way pipe 31, and this three-way pipe 31 is communicated with water fountain water tank, pressure valve 1 water inlet end and back-water valve (BWV) 2 water inlet ends respectively.Connection through three-way pipe 31; Water inlet pipe, pressure valve 1 and back-water valve (BWV) 2 are connected together; And when there was the not enough situation of steam or hydraulic pressure in water inlet end, the spool 12 that current can not be pushed spring 13 roof pressures open flow to outlet pipe, with the hydraulic pressure of guaranteeing outlet pipe and the stability of current.The water side of back-water valve (BWV) 2 is provided with back pressure pipe 4; Back pressure pipe 4 is communicated with the water fountain water tank; The effect of back pressure pipe 4 is when hydraulic pressure in the supply channel and waterflow stabilization, with the hydraulic pressure of water-heater water tank back pressure is provided, and with the water side of back-water valve (BWV) 2 pressure is provided together; The spool 22 that ensures back-water valve (BWV) 2 can be because of hydraulic pressure open by mistake, and prevents the hot water into water-heater water tank that flows backwards.In order to realize that back pressure pipe 4 can provide stable back pressure, three-way pipe 32 is set on the water side of back-water valve (BWV) 2, three-way pipe 32 is communicated with back-water valve (BWV) 2, water fountain water tank and back pressure pipe 4 respectively.The family expenses instant heating type drinking device combination valve of the utility model can have been avoided jet phenomenon, improves the security that water fountain uses.
Above-mentioned specific embodiment is merely the utility model effect specific embodiment preferably, and the identical or equivalent configurations of family expenses instant heating type drinking device combination valve of all and the utility model is all in the protection domain of the utility model.
