Described control system 3 comprises PLC301, signal picker 302, control panel 303 and computer 304, and described PLC301 is connected with vertical stepper motor 104, horizontal circumference stepper motor 106, backwater solenoid valve 205, hot and cold water flowmeter 208, hot water pipe air valve 209, signal picker 302, control panel 303, computer 304 respectively; Described signal picker 302 is connected with hot and cold water temperature-sensitive head 214, water outlet temperature-sensitive head 202, signal picker 302, computer 304 respectively; Described control panel 303 is connected with computer 304.
The using method of this practical checkout equipment is:
Detection for " sensitivity and nerve " parameter: the warm-cold inleting pipe 5, rising pipe 6 and the flowing water joint 201 that connect tested water swivel 4, by the handle connection fixture 107 of tested water swivel 4, connect the handle 7 of tested water swivel 4, open hot and cold water pump 211, and move PLC301.By horizontal circumference stepper motor 106, driving tested water swivel 4 to do circular-rotation moves, drive tested water swivel 4 from complete cold position (ultra-Right), to start to rotate to hot water direction with the speed of 0.5 °/s, while arriving full thermal site (ultra-Left), with same speed, be back to complete cold position at once.
A, analog temperature detect: the hot and cold water data synchronous transmission that the data of horizontal circumference stepper motor 106 motions and hot and cold water flowmeter 212 are collected, to PLC301, converts signal to and is input in computer by signal picker 302.Computer expert crosses the unit rotational angle of collecting horizontal circumference stepper motor 106, and the faucet outlet temperature that synchronous collection calculates to the flow proportion of cold water and hot water forms following " rotational angle-water temperature " curve map, as shown in Figure 2 and Figure 3.
From cold water to hot water process, the water swivel angle position P01 when temperature reaches 34 ℃, the water swivel angle position P02 when temperature reaches 42 ℃, computer calculates angle value (sensitivity) G1=P02-P01 in this scope automatically; From hot water to cold water process; Water swivel angle position P11 when temperature reaches 42 ℃, the water swivel angle position P12 when temperature reaches 34 ℃, system is calculated angle value (sensitivity) G2=P11-P12 in this scope automatically.
Meanwhile, from cold water, to hot water process, when water swivel angular movement is extremely central, the water temperature of (cold/hot water is equal, is set as 0 ° on software) is T1; From hot water, to cold water process, the water temperature when water swivel angular movement is extremely central is T2, and computer calculates these two deviation temperature (nerve) F=T2-T1 automatically.
B, actual temperature detect: cold/hot water reaches the temperature of appointment, the data of horizontal circumference stepper motor 106 motions convert signal to by PLC and are input in computer by signal picker 302, and synchronous collection to water delivering orifice water temperature data by signal picker 302, be input to computer, form " rotational angle-water temperature " curve map (shown in same Fig. 2, Fig. 3).Automatically calculate G1, G2 and F value method the same.
Detection for " consistance " parameter: each parts annexation is the same, first by horizontal circumference stepper motor 106, drive tested water swivel 4 as circular-rotation, to be moved to cold water direction by hot water, the variation of PLC301 monitoring water temperature, when water temperature is down to 38 ℃, horizontal circumference stepper motor 106 quits work, and vertical stepper motor 104 starts to make closing motion with the handle 7 of the tested water swivel of speed drive of 0.5 °/s.When computer is collected water delivering orifice fluctuations in discharge, synchronous collection, to the variation of water delivering orifice temperature, forms " flow-temperature " curve map, as shown in Figure 4.
From whole process, it is T0 that computer is collected the instantaneous temperature that tested water swivel 4 starts to do closing motion, and when tested water swivel 4 water delivering orifice flows are reduced to 6L/min, record this water temperature is T1 moment, while continuing to reduce flow to 3L/min, record this water temperature is T2 moment.System automatically calculate these two flow values difference (consistance) the △ T1=[T0-T1 of water temperature and initial water temperature], △ T2=[T0-T2].
More than show and described this practical ultimate principle and principal character and this practical advantage.The technician of the industry should understand; this practicality is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates the principle that this is practical; do not departing under the prerequisite of these practical spirit and scope; this practicality also has various changes and modifications, and these changes and improvements all fall in this claimed usage range.This real requirement protection domain is defined by appending claims and equivalent thereof.
