Description
Technical field
The utility model is related to a kind of water mixing valve structure, and in particular to a kind of anticreep thermostatic valve.
Background technology
The lower water temperature of water heater realizes that the two ends of water mixing valve connect hot-water line and cold water respectively by water mixing valve
Pipe, as shown in Figure 1, the spanner of water mixing valve is rotated between left and right, and the water of two kinds of temperature is proportionally mixed inside water mixing valve
Get togather with regard to the water temperature that we want can be formed, it is desirable to heat a little just deviation the left side some, it is desirable to it is colder just deviation on the right of one
A bit, it is desirable to which water is big a little just to be pulled upwards, it is desirable to which water is a little bit smaller just to be pulled downwards, and the cold and hot water mixed is just by an other outlet pipe
Export comes for people to use.But during real use, people are often armrest sense when pulling spanner to hold position
, it is impossible to the temperature level and current size corresponding to position are known exactly, and when down pulling closing water valve, by
In that can not accurately control dynamics, the right position of spanner is changed, and the mixed cold and hot water ratio regulated is also become
Change, when next time is again turned on water valve, it is impossible to return to ratio that last time regulated, it is necessary to readjust again, use is more numb
It is tired.
Closed electric water heater with water tank, all installs a relief valve with check-valves in water inlet, is referred to as safety valve.When
Water heater energization heating process, the coolant-temperature gage rise of inner bag, pressure is increased and need to drained from pressure release, inner bag constant pressure is kept, in safety
In the water inlet of valve, provided with one way stop peturn valve, prevent when water supply line is cut off the water, the water of protection inner bag will not be from water supply line
It is lost in, and causes heat-generating pipe dry combustion method accident, one way stop peturn valve closes water inlet by means of spring reset.In the heat used in water heater
During water, when opening water mixing valve regulation mixes water leaving water temperature, in the unblocked entrance water mixing valve of cold water, another strand of water pushes unidirectional stop open
To valve, inner bag is entered back into, hot water is passed out into water mixing valve is mixed, and running water pressure is reduced caused by hydraulic pressure is by external influence
Or increase, unidirectionally only valve is by influence of hydraulic pressure, and valve element and valve seat opening travel are fluctuated, and heat supply water is also suddenly neglects more therewith
Few, causing the imbalance of mixing valve water outlet proportion to occur, leaving water temperature is sometimes hot and sometimes cold, and the prominent high-temperature water such as attacked can also scald skin, this
It is the hard nut to crack that water heater exists always.
