[specific embodiment]
The floor drain of the utility model embodiment 1 such as Fig. 1 are to shown in Figure 6.This floor drain comprises housing 1, drain cover 2, filter screen 3 and rubber check valve 4.Rubber check valve 4 comprises installation portion 4a and outlet part 4b.
The installation portion 4a of rubber check valve 4 is connected with the outlet part 1a of housing.The installation portion 4a of rubber check valve 4 is a cylindrical shape, and 1 a delineation position bead 401 is arranged at the top of installation portion 4a cylinder, at the external surface of installation portion 4a cylinder the outstanding seal band 402 in 4 roads is arranged.The location bead 401 of rubber check valve 4 is seated on the last plane of housing outlet part 1a, and outstanding seal band 402 in 4 roads and housing outlet part 1a cylindrical form interior surface interference fit are realized sealing.
The outlet part 4b of rubber check valve has the transition part 403 of wedge shape and the delivery port 405 of in-line, the inner surface of straight water outlet ofthe 405 is closed mutually, the rear end of straight water outlet ofthe 405 is connected with the port of export of installation portion 4a through the transition part 403 of wedge shape, transition part 403 has 2 skew walls 406 and 2 sidewalls 407,2 skew walls 406 cross to straight water outlet ofthe 405 places, and its angle is 52 °.The transition part of wedge shape is the easier delivery port of opening in-line under the pressure of draining, so in same crossing under the footpath, the mouth of a river, the rubber check valve with wedge shape outlet part is more much bigger than General Purpose Rubber non retern valve drain discharge.And the rubber check valve with wedge shape outlet part can be done shortlyer than the draining of General Purpose Rubber non retern valve.
Filter screen 3 is provided with the top that is housing outlet part 1a, the water part of the intake section of housing 1 and housing separated to prevent that bigger foreign material from entering sewer, avoid foreign material that sewer is stopped up, or the delivery port of rubber check valve 4 is blocked, rubber check valve was lost efficacy.
The floor drain of the utility model embodiment 2 such as Fig. 7 are to shown in Figure 9.As different from Example 1, comprise transit joint 5.Transit joint 5 comprises cylindrical shape installation portion and connecting portion.Location bead 505 is arranged at the top of transit joint cylindrical shape installation portion 501, the endoporus of transit joint cylindrical shape installation portion 501 and housing outlet part 1a is for movingly, there are 2 road O-ring seals 7 to seal between the periphery of transit joint cylindrical shape installation portion 501 and the housing outlet part cylindrical form interior surface, prevent that draining is from this seepage.The installation portion 4a of rubber check valve 4 is sleeved on the transit joint connecting portion 502.The inner surface of the installation portion 4a cylinder of rubber check valve 4 has the outstanding seal band 402 in 1 road, and lock ring forms sealing on transit joint connecting portion 502.There is a circle seam 503 lower end of transit joint connecting portion 502, is stuck in the lower end of seal band 402, can prevent that rubber check valve from coming off.To shown in Figure 9, the wall thickness of 2 skew walls 406 of wall ratio of 2 sidewalls 407 is much bigger as Fig. 7, and the thickness of straight water outlet ofthe 405 is also very little, and the thickness of skew wall 406 is suitable basically.The wall thickness of sidewall is big, can improve the integral rigidity of rubber check valve, is not having under the situation of hydraulic pressure, makes straight water outlet ofthe 405 closures, helps not having the sealing of depressing; The thickness of skew wall 406 and straight water outlet ofthe 405 is very little, and is flexible good, also helps strengthening displacement under hydraulic pressure.In the present embodiment, 2 sidewalls 407 are same cylinder with the outlet position of installation portion 4a, so the thickness L1 of 2 sidewalls 407 is identical with the thickness L2 in installation portion 4a exit, are all 2 millimeters; The wall thickness M of 2 skew walls 406 is 0.4 millimeter, and is more much smaller than the thickness of 2 sidewalls 407.The thickness of straight water outlet ofthe 405 equals skew wall 406 wall thickness, and its wall thickness N also is 0.4 millimeter.Because the closed performance of present embodiment rubber check valve is good, the height H of straight water outlet ofthe only needs 5 millimeters, helps reducing the overall height of rubber check valve.
The filter screen 504 of present embodiment is arranged on the top of transit joint, the water part of the intake section of housing 1 and housing is separated can prevent that bigger foreign material from entering sewer.
Transit joint cylindrical shape installation portion 501 adopts movingly with the endoporus of housing outlet part 1a, adopts O-ring seals to seal between the two, transit joint 5 can be taken off from housing 1, changes rubber check valve easily.
The utility model the foregoing description has reduced the height of floor drain widely.Rubber check valve has adopted the delivery port of the in-line closure of wedge shape transition, and drain discharge is bigger three times than traditional rubber check valve, and has improved the counter-pressure of shutoff, can prevent the anti-excessive of foul smell.Rubber check valve can prevent to play health in the household environmental protection holding chamber in the reverse inlet chamber of small worm, bacterium in the gutter, improves the environmental quality of household, anticlogging effect.
