Abstract
The invention relates to and be used for cooperating one group of Floor drain pipe installing with a tiny waste material drain.Comprise a major diameter drain body, a upper flange is arranged on it, this body upper end radial outward is extended certainly; One lower flange, this body lower end radial inward is extended certainly, forms a bottom hole opening; Also comprise a tubulose coupling member, pass the following hole of body, the flange that has a radial outward to extend on it places body lower flange top in the mode of facing mutually.External screw thread is all arranged on drain body and the connecting elements, is connected with exterior nut cap, in order to fixing drain body in the floor and will link flange and body lower flange and fix and be sealed togather.The connecting elements lower end can fixedly connected tiny waste material drain.
Description
In water pipe supply industry, many standardized products are produced in the scope of standard size or diameter.Particularly a series of Floor drain pipes may comprise that the very big gutter of vary in diameter is to be fit to the draining needs of wide scope.Equally, the waste material drain also is all can obtain a series of diameter (and material) person, to be fit to extensively different needs.But the major diameter Floor drain pipe normally is designed in order to linking large diameter waste material drain, because this general purposes that is it.Unfortunately, therefore be difficult to when needed large diameter gutter is connected in the coupled system that uses thin waste material drain.Though can use the undergauge coupling member of standard, the common space, narrow and small zone between ceiling and flooring structure is too little can not to utilize this device.Therefore, perhaps need less, more inapplicable gutter, perhaps bigger pipe must detour to enough space utilization reducer couplings place are arranged.Arbitrary mode all makes piping work can not reach the best.
The present invention generally includes a counter floor gutter, is arranged in a thin waste material drain in order to cooperation.The present invention includes a large diameter cylindrical shape drain body, this body has a flange that is extended and flushed with floor surface usually by its upper end radial outward.Drain body comprises external screw thread, and this external screw thread is in order to fix a top exterior nut cap, and the latter is used for compressing rank and closes in the floor downside.One roomy below flange is inwardly done radially to extend by its lower end, forms a narrow following hole.One tubulose coupling member extends through down the hole, and comprise by do that warp-wise extends one on flange connector, the size of this flange is designed to be configured in directly over the drain body lower flange.
Coupling member also includes external screw thread, and this external screw thread is in order to fix a below exterior nut cap, and the latter is used for being connected to flange outside, below.Fill out circle and be located between binding flange and the below body flange, and be located between below body flange and following square nut, make down square nut compress coupling member and drain body airtight at following hole opening part.Thin waste material drain can standard technique be fixed in the lower end of coupling member.
The accompanying drawing summary:
Fig. 1 is the phantom drawing that is installed on the gutter member of the present invention in the floor.
Fig. 2 is the drawing in side sectional elevation of drain assembly of the present invention.
Fig. 3 is a drain assembly exploded view of the present invention.
The present invention comprises the drain assembly in a big footpath substantially, designs in order to be connected in a waste material drain than path especially.With reference to figure 2 and 3, drain assembly 11 comprises a drain body 12, is generally hollow round tubular.Flange 13 extends into ring-type by drain body upper end radial outward.This flange comprises an annular recessed portion 14, and this recess is used for adorning a filter screen (not shown).The outside top of drain body 12 partly is provided with screw thread 16, closes in order to hold in the mouth mutually with an exterior nut cap 17 that is provided with identical screw thread.
As shown in Figure 2, drain body 12 is passed a hole in the floor 18 and is stretched out, and its flange 13 is put into around an annular recessed portion in this hole and with floor upper surface and flushed.One packing ring 19 also is loaded in the annular recess simultaneously with flange 13, another packing ring 21 then be configured in nut 17 directly over.Oppressed the screwing drain body is fixed in the hole and with the floor of nut forms sealing.
Drain body 12 also is provided with a below flange 22 that is extended by its lower end radial inward.Flange 22 is more roomy, and is that drain body forms a narrow following hole opening.
A striking features of the present invention is the coupling member 26 that is provided with a tubulose, hollow.Member 26 is provided with one and links flange 27, and the diameter of flange 27 and drain body internal diameter are about equally.Binding flange 27 is used for placing gutter flange 22 tops, below and faces mutually with the latter, is equipped with a closed-loop 28 between the two.The upper section of coupling member also is provided with external screw thread 29, and the latter is fixed in a nut 31 around it.This nut is used for having a closed-loop 32 to be located at therebetween in butt drain body lower end.
The tubular portion diameter that it should be noted that coupling member 26 equals a standard waste drain diameter, and the latter is less than the intended diameter of most of big drain body.Coupling member can be connected in identical waste material drain by common unit (for example being fixed with the sleeve of suitable cementing agent etc.).Nut 31 screwed with compressing rank close in flange 27 and 22 with the gutter lower end, seal to form with coupling member and waste material drain system.
The present invention also provides bigger changeability for the combination of piping system. For example, can make a series of coupling member to each drainpipe ontology model, each coupling member undergauge is to different standard waste drain diameters. Each coupling member is provided with identical flange 27, forming the sealing of a leakproof with drainpipe, and how is regardless of the waste material drain diameter that is connected.
