Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described with embodiment.
As shown in Figure 1, Figure 2, shown in Fig. 4 and Fig. 5, sets forth the axonometric chart of life detecting device of the scrubbing water filter element of the present invention, front view, right view and top view, Fig. 3 gives its sectional view, the life detecting device of shown scrubbing water filter element is made up of housing 1, left barrier film 4, right barrier film 5, fork 9, contact switch 10, the inside of housing 1 is cavity, and the two ends of housing 1 are right inlet channel 2, left inlet channel 3.Left barrier film 4, right barrier film 5 may be contained within the internal cavities of housing 1, form right water storage cavity 7 between right barrier film 5 and right inlet channel 2, and right water storage cavity 7 communicates with the water inlet of filter element to be detected；Forming left water storage cavity 6 between left barrier film 4 and left inlet channel 3, left water storage cavity 6 communicates with the outlet of filter element to be detected.Shown right inlet channel 3 and the outer wall of left inlet channel 2 are provided with the screw thread of interconnection function or have connect the plug-in unit of mode soon, to realize the connection with exterior line.
Being central cavity 8 between shown left barrier film 4 and right barrier film 5, central cavity 8 and left water storage cavity 6, right water storage cavity 7 are all not communicated with.Offering through hole 11 on housing 1 above central cavity 8, contact switch 10 is fixed on the housing 1 at through hole 11 place；Fork 9 is configured through through hole 11, and in the centrally located cavity 8 in lower end of fork 9, upper end stretches out in through hole 11 and matches with contact switch 10.Fork 9 is arranged on housing 1 by rotating mechanism, rotating mechanism is made up of rotating shaft 12 and U-shaped frame 13, and two U-shaped framves 13 are fixed on the both sides of through hole 11, and the both sides of fork 9 are respectively and fixedly provided with rotating shaft 12, two rotating shafts 12 are respectively placed in two U-shaped framves 13, to ensure that fork 9 can 12 swing around the shaft.
After the life detecting device of the present invention is installed to the filter element two ends of filter element or multiple cascade, the hydraulic pressure in right water storage cavity 7 is equal with the hydraulic pressure in filter element water inlet, and the hydraulic pressure in left water storage cavity 6 is equal with the hydraulic pressure in filter element outlet.Along with filter element uses the prolongation of time, the filter capacity of filter membrane is gradually lowered, its water penetration is gradually lowered, water inlet can be made to become big with the pressure reduction of outlet, when pressure reduction increases to after to a certain degree, the deformation that can make right barrier film 5 is relatively big, and then the amplitude ordering about fork 9 swing is relatively big, finally makes the switching state of contact switch 10 change.The state of contact switch 10 changes and life-span of this state representation filter element can be kept in stipulated time section most, need to change filter element, when the state of contact switch 10 occurs to change in short-term, namely processes as misoperation.This filter element life detecting method, compared with changing filter element with regular or the fixed net water yield, can reflect the actual state of filter element truly, objectively, both ensure that clean-up effect, turn avoid the waste changing filter element too early.
As shown in Figure 7 and Figure 8, give the structural representation of contact switch 10, shown contact switch 10 is provided with contact 19, spring leaf 17 and 3 pins 18, spring leaf 17 is positioned at the outside of contact 19, spring leaf 17 towards contact switch 10 swing time, contact 19 can be pressed to and then make the switching state of pin 18 change.The upper end of fork 9 contacts with spring leaf 17, when spring leaf 17 being made to press to contact 19 in the process that fork 9 swings, makes the state of contact switch 10 change.
Shown housing 1 is fixed with the two fixing plates 15 being parallel to each other, contact switch 10 is fixed between two fixing plates 15, offering rectangular pressure reduction regulating tank 15 on fixing plate 15, contact switch 10 offers fixing hole 20, fixing hole 20 is fixed in pressure reduction regulating tank 16 by fixing axle 28.By changing the fixing hole 20 fixed position on pressure reduction regulating tank 16, distance between adjustable springs sheet 17 and fork 9 top, and then changing the fork 9 required angle swung when contact switch 10 on off operating mode changes, it is achieved pressure reduction regulates, the final life tests regulating filter element.
As shown in Figure 5, it is shown that housing 1 be made up of right shell body 21, intermediate 22 and left shell 23, right barrier film 5 is between right shell body 21 and intermediate 22, and left barrier film 4 is between left shell 23 and intermediate.As it is shown in figure 9, give the structural representation of right shell body 21, it is shown that right shell body 21 on be provided with right water inlet pipe 24, the central authorities of right water inlet pipe 24 offer right inlet channel 2.Figure 11 gives the structural representation of intermediate 22, it is shown that the both sides of intermediate 22 be provided with the Sealing shield ring 26 matched with left barrier film 4 and right barrier film 5, to ensure the sealing of left water storage cavity 6 and right water storage cavity 7.Figure 12 gives the structural representation of left shell 23, and left shell 23 is provided with left water inlet pipe 27.In 3, it is shown that the lower end of fork 9 be fixed with tup 14；Figure 10 gives the structural representation of left barrier film 4 or right barrier film 5, it is shown that left barrier film 4 and the central authorities of right barrier film 5 be provided with the projection 25 matched with tup 14.
The life detecting device of the scrubbing water filter element of the present invention, by by the pressure on filter element or multi-stage filter core water inlet compared with the pressure on outlet, when pressure differential exceedes the threshold value of setting, then it is assumed that the service life of filter element is most, filter element need to be changed.The life detecting method of this dependence pressure differential, can truly reflect the actual filtration ability of filter element, with existing regularly or according to compared with filtering the water yield and change the method for filter element, more conforming to reality, both ensure that the quality of filtering water, turn avoid the waste changing filter element too early.
