In above-mentioned electric heater, assembly has quick-opened valve core to be connected with cold water tube connector or hot water tube connector in aforesaid each knob handwheel.The effect of quick-opened valve core is in time freely to regulate the size of water outlet.
In above-mentioned electric heater, an end of described mixed water pipe also is provided with relief valve.The setting of relief valve in the time of can preventing that the heating of the excessive or water heater of cold water pressure from producing excessive pressure (heat expansion shrinkage), can release more than the water of specified pressure by relief valve, can effectively protect water heater.
In above-mentioned electric heater, check-valves is installed also in the cold water inlet of described cold water pipe.Only press the effect of valve to be, when cold water was cut off the water, check-valves can prevent that the water of water heater the inside from refluxing.
In above-mentioned electric heater, an end of described hot water pipeline also is provided with the standby delivery port of hot water.The standby delivery port of hot water can provide standby for the use of hot water.
In above-mentioned electric heater, described water inlet of hot water is imported and exported with cold water and is connected with the cold water interface with each self-corresponding electric heater main body interface of hot water with the attaching nut.Only just can connect the corresponding interface of the interface of electric heater and water valve mechanism with two attaching nuts, the water valve mechanism that has solved general electric heater is provided with the problem that a plurality of accessories and a plurality of interface are installed together.
In addition, water valve of the present invention mechanism substantially all is by injection molding, greatly reduces production cost.
The present invention compared with prior art has the following advantages:
1. an anti-electric valve has all been installed at cold water delivery port place in the water valve mechanism of electric heater and water inlet of hot water place separately, and many one deck earth leakage protectives have improved security performance greatly.
2. water is sent out service life and the safety that the relief valve that is provided with in the mechanism and check-valves have been protected electric heater greatly.
3. the water valve mechanism body of electric heater is to form with plastic injection-moulded, reduces production costs greatly.
4. be connected with the electric heater interface by two attaching nuts in the water valve mechanism, solved the problem that a plurality of interfaces of the general a plurality of accessories of electric heater water valve mechanism are adorned together.
