Technical background
Usually, the method that is used to control room temperature can be divided into two classes according to thermometric method, that is measures room temperature and measure circulating water temperature.
Preceding a kind of method is by measuring the amount of room temperature control recirculated water, and is constant so that the temperature in room keeps.In the method, a controller is placed in the room, thereby the operation of controller is more convenient; But the scope of measured temperature can't meet the temperature of sensation.And in the time of in a sensor is placed into a main room, the temperature difference in other room is very big, therefore is difficult to keep all temperature to be in steady state always.And the another one problem is: very slow from the reaction time between the variation that changes to room temperature of the thermal cycle water yield in formula (hypocaust) structure of Korea S hole, even therefore in same room, the excursion of room temperature is also very big.
And in back a kind of method of measuring circulating water temperature, it is fast that the base area plate temperature changes the adjusting of being carried out, and the scope of variations in temperature is very little.In addition, thus controlling temperature by the temperature of measuring the recirculated water intersection in each room makes each room in house with hole formula structure all remain on a suitable temperature.But, because the controller that is made for one with valve body is positioned at a distributor water tank under, therefore unusual inconvenience.
Fig. 1 is the partial sectional view of the sensitive control valve internal structure of an expression coolant-temperature gage of the prior art.
Referring to Fig. 1, the sensitive control valve of this coolant-temperature gage comprises valve body 1, and this valve body 1 has oral siphon 11 and outlet pipe 21 of taking mouth 22 out of of a tape entry 12.A valve rod 30 is installed between oral siphon 11 and the outlet pipe 21.A disk body 17 forms as one with valve rod 30, is used for opening/closing outlet 22.A water temperature sensor 25 is arranged on the disk body 17, is used for directly measuring the temperature that adds hot water; A biasing spring 15 is set to disk body 17 belows, is used for upwards push-plate body 17.In addition, adjustment handle 19 and display 27 are installed to the upper end of valve rod 30, so the user can regulate the temperature in room and be easy to observe thermoregulator state.
In aforesaid control valve 1, heating back water temperature sensor 25 is measured the temperature of returning water, to regulate the hot water amount.Because water temperature sensor 25 is made by marmem, so it can expand or shrink according to circulating water temperature.When circulating water temperature is higher than when setting value, water temperature sensor 25 expands, thereby so disk body 17 move down and slowly close outlet 22.When circulating water temperature is lower than when setting value, water temperature sensor 25 shrinks, so disk body 17 moves up under the restoring force effect of spring 15, thereby opens outlet 22.Regulate according to the ON/OFF of valve, thereby the flow velocity that can regulate hot water keeps the homogenization temperature that sets.
But the speed that the sensitive control valve of above-mentioned coolant-temperature gage of the prior art is measured coolant-temperature gage is very slow.In addition, water temperature sensor 25 is made by marmem, and therefore As time goes on this sensor 25 may lose efficacy.As a result, can not finish measurement function under the state of optimizing, the ON/OFF that therefore weakens valve is regulated.
In addition, contain the various for example lime powders of material that swim in the water, these materials may be deposited on the pipeline or be stacked on these parts, thereby have stoped flowing or having hindered the operation of these parts of hot water.In other words, between biasing spring and the valve rod swim material for example the precipitation of lime powder injured the function of the sensitive control valve of coolant-temperature gage, this may make valve not work.
