Abstract
The present invention relates to a group of floor drain pipes assembled with a fine waste material discharge pipe, and each of the floor drain pipes comprises a drain pipe body with a big diameter and a tubular connection component, wherein an upper flange and a lower flange are arranged on the drain pipe body, the upper flange outwards extends from the upper end of the body in the radial direction, and the lower flange inwards extends from the lower end of the body in the radial direction and forms a lower hole opening; the tubular connection component penetrates through the lower hole of the body, and a flange which outwards extends in the radial direction is arranged above the lower flange of the body face to face; outer threads are formed on the drain pipe body and the connection component, are connected with outer screw caps, and are used for fixing the drain pipe body to a floor and fixing and sealing the flange of the connection component and the lower flange of the body; the lower end of the connection component can be fixedly connected with the fine waste material discharge pipe.
Description
The present invention relates to be used for cooperate the counter floor gutter of installing with thin waste material drain.
In water pipe supply industry, produced many standardized products in the scope of standard size or diameter, particularly a series of Floor drain pipe comprises that various gutters that diameter dimension alters a great deal are to be fit to needs widely.Equally, the waste material drain of a series of diameters (and material) is also arranged, to satisfy various needs.But the major diameter Floor drain pipe normally is designed in order to connecting large diameter waste material drain, because this prevailing purposes that is it., in the time large diameter gutter need being connected in the coupled system that uses thin waste material drain.Though can use the undergauge connecting elements of standard, between ceiling and flooring structure, not have enough spaces to use this device.Therefore, perhaps must use more inapplicable undersized gutter, perhaps use bigger pipe, with it around the space that can use reducer coupling to one.More than any mode all make piping work can not reach optimum efficiency.
The objective of the invention is to propose a kind of counter floor gutter that can cooperate installation, to overcome the problem that exists in the above-mentioned piping work with the tiny waste material drain.
The present invention generally includes a counter floor gutter, in order to cooperate a thin waste material drain is installed.The present invention includes a large diameter cylindrical shape drain body, this body has a upper flange that is extended and flushed with floor surface usually by its upper end radial outward.External screw thread is arranged on the drain body, and this external screw thread is in order to fix a top exterior nut cap, and the latter compresses and is connected in the floor downside.Also have a roomy lower flange inwardly radially to extend on this drain body, form a narrow aperture by its lower end.One tubular connection passes down the hole, and has a last flange connector by its upper end outward radial extension, and the size of this flange is designed so that flange configurations is directly over the drain body lower flange.
Also have external screw thread on the connector, this external screw thread is in order to fix a below exterior nut cap, and the latter closely is connected in flange outside, below.Between flange connector and the body lower flange, and be provided with packing ring between body lower flange and the following square nut, make down square nut connecting elements and drain body be compressed sealing at the place, aperture.Can fixedly connected with thin waste material drain by general technology in the lower end of connector.
Fig. 1 is the phantom drawing that is installed on the gutter 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 generally comprises a large diameter drain assembly, designs in order to be connected in a waste material drain than minor diameter especially.With reference to figure 2 and Fig. 3, drain assembly 11 comprises a drain body 12, is generally hollow round tubular.Upper flange 13 extends into ring-type by drain body upper end radial outward.This flange has an annular recessed portion 14, and this recess is used for adorning a filter screen (not shown).The outside upper section of drain body 12 promptly is provided with screw thread 16 near flange 13 belows, in order to match 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.Packing ring 19 also is loaded in the annular recess simultaneously with upper flange 13, another packing ring 21 then be configured in nut 17 directly over.Nut is screwed drain body is fixed in the hole and with the floor forms sealing.
A striking features of the present invention is for being provided with a tubulose, hollow connecting member 26.Connector 26 has a flange connector 27, and the diameter of flange 27 and drain body internal diameter are about equally.Flange connector 27 places gutter lower flange 22 tops and faces mutually with the latter, is equipped with a closed-loop 28 between flange connector 27 and the lower flange 22.The upper section of connector is provided with external screw thread 29, fixes a nut 31 on it.Nut 31 is pressed on the connector lower end, is provided with closed-loop 32 between body and nut 31.
The tubular portion diameter that should be noted that connector 26 equals a standard waste drain diameter, and the latter is less than the intended diameter of most of big drain body.Connector can connect with common unit (for example being fixed with the sleeve of suitable cementing agent etc.) and identical waste material drain.By screwing nut 31, make nut 31, flange 27,22 and packing ring 32,28 fluid-tight engagement form sealing with connector 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 connector to each drain body, each connector undergauge is to different standard waste drain diameters.No matter connected waste material drain diameter, each connector is provided with same flange 27, to form a leak proof seal with gutter.
