Fig. 2 is the sectional view along the line 2-2 among Fig. 1;
Fig. 3 is the sectional view along the line 3-3 among Fig. 1;
Fig. 4 is the vertical view of floating pressure type backflow proof shown in Figure 1 every device.
The specific embodiment
The concrete structure of floating pressure type backflow proof of the present utility model every a kind of embodiment of device is described with reference to the accompanying drawings.
As shown in Fig. 1 to 4, floating pressure type backflow proof of the present utility model comprises a columnar shell body 2 every device 1, the middle part of the roof 3 of this shell body 2 has a water inlet 4, generally can make flue, around being provided with a plurality of water-exit verticallies hole 6, also can be provided with a plurality of horizontal weep holes 8 at the outer circumferential position of the diapire 5 of shell body 2 in the position by diapire 5 of the side tube-wall 7 of shell body 2.The inner surface of roof 3 around water inlet 4 places one O-ring seal 9 is set, fixing on the throne by the spring Figure 10 that rises, this O-ring seal 9 plays a valve seat.
As can be seen from Fig. 1, be provided with the cylindrical shape inner housing 12 of a sealing in the centre position of the diapire 5 of shell body 2, the centre position of the top cover 13 of this inner housing 12 is provided with a lead ring 14, is provided with some inlet openings 15 in the outside by lead ring 4 of top cover 13, is two inlet openings 15 shown in the figure.By inlet opening 15, can in inner casing 12, fill water 16.
Shown in Fig. 1, floating pressure type backflow proof of the present utility model also comprises a valve gap float component 20 every device 1, and this valve gap float component 20 comprises that one is placed in the cylindrical shape floating drum 21 of the sealing in the inner housing 12; The seal cover 22 of one arch, when its O-ring seal that plays the valve seat effect 9 with water inlet 4 places of shell body 2 engages, can be with water inlet 4 closures; And a slide bar 23 that connects seal cover 22 and floating drum 21, this slide bar 23 is preferably hollow, and with weight reduction, this slide bar 23 is contained in the lead ring 14 on inner housing 12 top covers 13 slidably.As can be seen from Fig. 1, when filling water 16 in the inner casing 12, under the buoyancy of water effect, floating drum 21 is floated, thereby make seal cover 22 upwards lean O-ring seal 9, water inlet 4 closures.Be provided with a plurality of centralized positioning parts 24 at the outer peripheral edges place of floating drum 21, the positioning action when assisting floating drum 21 in inner casing 10, to move up and down.
Shown in Fig. 1 and 4, also can be provided with the separator 27 of a band grid at floating pressure type backflow proof above the roof 3 of the shell body 2 of device, its floating pressure type backflow proof also can stop foreign matter to enter floating pressure type backflow proof every device from water inlet 4 every the sealing role of device.
Floating pressure type backflow proof of the present utility model is suitable for being installed in the below of the outfall (not shown) of bathtub or basin every device.When bathtub or basin not during draining, the buoyancy of the water 16 in the inner housing 12 floats floating drum 21, can make seal cover 22 lean sealing ring 9 and with water inlet 4 sealings.Therefore, sewage that refluxes in the escape canal (not shown) and dirty gas etc. can not be back to indoor by outfall.When carrying out draining, the water that enters water inlet 4 makes seal cover 22 to sinking by its weight or pressure, thereby opens water inlet 4, and via the water-exit vertically hole 6 of shell 2 or laterally weep hole 8 be discharged in the escape canal and go.When not having the weight of water or pressure, floating pressure type backflow proof just can float once more automatically every the seal cover 22 of device water inlet is sealed.So, can prevent that sewage and dirty gas are back to indoor.
Introduced of a kind of preferred embodiment of the floating pressure type backflow proof of the utility model above in conjunction with the accompanying drawings every device, but, the utility model is not limited, and those of ordinary skills can both understand, and can make various changes and remodeling in spirit and scope of the present utility model.For example, in the present embodiment, shell body 2 is a kind of drums, but it can be four limits or polygon cylindrical form.In addition, inner housing 12 and floating drum 21 shown in the accompanying drawing of present embodiment are being cylindrical shape, but it also can be four limits or polygon tubular.
In the present embodiment, employing be the structure of floating drum 21, but also can adopt the structure of ball float.In the present embodiment, seal cover 22 adopts domes, is that dirt is unlikely to attach thereon in order to make, but also is not limited to this arcuate in shape and can adopts flat shape.
