Embodiment
As Fig. 2 to Fig. 4, the backstop structure of a kind of outlet valve that the utility model the first embodiment provides, its mainly by a valve body 20, one first pipe assembly 30, one second pipe assembly 40, a plug member 50, and a spring 60 formed, wherein:
This valve body 20, comprise one first water outlet 21, one second water outlet 22, a water intake 23, reach a control knob 24, wherein this water intake 23 is arranged in a water filter (not showing on figure), 24 of this control knobs can be controlled the water purification of selecting by after this first water outlet 21 or second water outlet 22 these water purifier filtrations of output, because this valve body 20 is existing member, and its structure and to make flowing mode all identical with existing member, also non-improvement emphasis of the present utility model, therefore for the detailed construction of these valve body 20 members with make flowing mode and no longer describe in detail.
This first pipe assembly 30, be arranged at this valve body 20, and have a first passage 31 that is the perforation shape and is communicated with this second water outlet 22, a plurality of flanks 32 that equidistantly are laid in these first passage 31 internal ring wall faces, and form a water channel 33 between every adjacent this flank 32; In the present embodiment, these the first pipe assembly 30 direct forming, on this valve body 20, and have more first spiro union portion 34 away from this second water outlet 22.
This second pipe assembly 40, be arranged in this first pipe assembly 30, and have one and be and connect shape and the second channel 41 is communicated with this first passage 31, reach a stopper 42 that is convexly set in these first passage 41 internal ring wall faces; In the present embodiment, this second pipe assembly 40 has more the second spiro union portion 43 that a spiral shell is located at this first spiro union portion 34, makes this second pipe assembly 40 firmly be arranged in this first pipe assembly 30; In addition, this stopper 42 has a through hole 421 in the form of a ring, makes this second channel 41 keep connecting shape and being communicated with this first passage 31; And this second pipe assembly 40 has more a water pipe belled part 44, by this water pipe belled part 44 is nested with for a water pipe 91, is communicated to a water storage barrel 92.
This plug member 50, can be located between this first and second passage 31,41 and with displacement respectively between this flank 32, this plug member 50 have one in order to sealing or open this second water outlet 22 piston part 51, and one be in reverse to 51De end, this piston part 52; In the present embodiment, the end face in this end 52 convexes with a post section 53.
This spring 60 is a Compress Spring, be arranged in this first and second passage 31,41, and have and one support first butted 61 of terminating in these plug member 50 ends 52, and one be in reverse to this first butted 61 and support second butted 62 that terminates in these the second pipe assembly 40 stoppers 42, this first butted 62 and be set in all sides of these plug member 50 post sections 53, make this first butted 61 to support that to terminate in these plug member 50 ends 52 more firm.
The above is structure and the configuration explanation thereof of the utility model first each main member of embodiment.
By this, as Fig. 2, Fig. 4, shown in figure figure, with regard to this water filter, filter, water storage, water purification after this water purifier filtration can be via the second water outlet 22 of this valve body 20, the first pipe assembly 30, the second pipe assembly 40, water pipe 91, finally flow in this water storage barrel 92, should be noted that, make this water filter in the process of drainage, the pressure produced is the elastic force that is greater than these spring 60 these plug members 50 of pushing and pressing, therefore, by this water purification, be able to the piston part of this plug member 50 51 is pushed away in this second water outlet 22, allow simultaneously this spring 60 accumulate an elastic restoring force, make water purification this second water outlet 22 of flowing through, and via this first the pipe assembly 30 each water channel 33 flow to this second the pipe assembly 40 second channel 41, via water pipe 91, flow to again the interior storage of this water storage barrel 92, used filtration, the water storage operation.
As Fig. 2, shown in Figure 3, when what this water filter stopped filtration operation and this water storage barrel 92, height is set during higher than this valve body 20, because the water purification after filtering no longer produces pressure, the piston part of this plug member 50 51 is pushed away in this second water outlet 22, therefore, 60, this spring is passed this plug member 50 by elastic restoring force toward these the second water outlet 22 directions, and make the piston part 51 of this plug member 50 seal these second water outlets 22, accordingly, prevented water purification in this water storage barrel 92 by these the second water outlet 22 adverse currents to these valve body 20 inside, cause the first water outlet 21 seepages by this valve body 20, reach the purpose of avoiding water resource waste.
What deserves to be explained is, when what this water filter stopped filtration operation and this water storage barrel 92, height is set during higher than this valve body 20, by the setting of these water storage barrel 92 height higher than this outlet valve 20, make the interior hydraulic pressure produced of water storage barrel 92 obtain so that piston part 51 these second water outlets 22 of sealing of this plug member 50 are more certain.
As shown in Figure 6, the backstop structure of a kind of outlet valve that the utility model the second embodiment provides, its mainly by a valve body 20, one first pipe assembly 30, one second pipe assembly 40, a plug member 50, and a spring 60 formed, this second embodiment is identical with the first embodiment's structure and effect, therefore repeat no more, as for difference be in:
Respectively this flank 32 extension 321 that extended outwardly of this first pipe assembly 30, while making this second pipe assembly 40 be arranged in this first pipe assembly 30, this extension 321 is positioned at the second channel 41 of this second pipe assembly 40, uses and forms another enforcement state.
Below through the specific embodiment and the embodiment the utility model is had been described in detail, but these not form restriction of the present utility model.In the situation that do not break away from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection domain of the present utility model.
