Abstract

The utility model discloses a cylinder type floor drain, which is composed of an outer, a middle and an inner cylinder bodies, and the three cylinder bodies are sheathed. The outer cylinder body is composed of four sections of cylinders with unequal lengths and the diameters of the four sections of cylinders are from big to small, and the four sections of cylinders are arranged from top to bottom. The top of the middle cylinder body is provided with a ring surface which is provided with water inlet holes of various forms. The inner circumference of the ring surface is provided with inner screw threads. The middle cylinder body is sheathed in the outer cylinder body. The outer margin of the ring surface on the top of the middle cylinder body is arranged on a positioning table on the top of the outer cylinder body. The inner screw threads of the ring surface are screwed with outer screw threads on the inner cylinder body. The utility model is directly and vertically arranged on a floor as a section of vertical tube, and can be used as a connecting tube fitting of the vertical tube. The inverse overflow of sewage can be prevented, and a horizontal tube which is used for connecting the floor drain and a water drainage vertical tube and is independent of the floor drain is not needed being arranged.

Description

The cartridge type floor drain

The utility model relates to a kind of building plumbing system member, relates in particular to a kind of floor drain that is used for the inside and outside excess surface water of excretion device.

At present, be widely used in industry and civilian construction that the floor drain of excess surface water has inside and outside the excretion device: leak in anhydrous feud, odour-proof floor drain, high water-seal floor drain, the single channel floor drain, the binary channels floor drain, the triple channel floor drain, be not with washing machine drainage access port floor drain, top cover band washing machine socket floor drain, side-type floor drain etc., no matter how its external form structure and internal drainage flow channel shape change, its common feature is when mounted: " must floor drain and main drain be connected to each other with one section branch drain that is independent of outside the floor drain itself, and the water inlet position of floor drain and the branch drain elevation difference that inserts the main position is that floor drain is rely and prevented in the main sewage required discrepancy in elevation of instead overflowing." because being floor drain water inlet double-edged fine-toothed comb, floor drain water inlet position generally should be lower than ground 5～10mm, to realize so preventing that sewage instead overflows in the main, and then the branch drain that can only be connected with floor drain causes position certain below the ground level and inserts main again.Like this, the horizontal or perpendicular arm of floor drain itself just must appear being independent of in the installation of this layer floor drain at the ceiling of lower floor, and these arms should be arranged inspection hole so that clear and coherent toward contact, and its hidden processing often relies on the finishing furred ceiling or builds piping shaft by laying bricks or stones.

In residential construction, people often wish that oneself kitchen, toilet room top do not occur that similar sewage is done, arm.In addition, for duplex house, architectural need one deck be the position in sitting room or bedroom in this cover often, and there is the space of drainage two layers of corresponding layout washroom etc.For architectural attractive in appearance, so the dwelling house water supply and sewage work have just occurred, the shared dewatering horizontal tubes of sanitary ware such as lavatory pan, urinating bucket, bathtub, pot sink in this layer washroom, the kitchen are inserted the way of soil stack more than this layer ground level, yet, floor drain is owing to prevent the condition restriction that sewage instead overflows, its branch drain still must appear at the usage space of this layer below ground, still can be to people's finishing and clear and coherent many inconvenience and the trouble brought of drainage pipe.

The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of and realizes preventing that sewage from instead overflowing, and is independent of outside the floor drain itself but needn't be provided with one, is used to connect floor drain and soil stack and forms the novel floor drain of the branch drain of the excessive discrepancy in elevation of counnter attack.

The purpose of this utility model is achieved in that a kind of cartridge type floor drain of design, be by outer, in, interior three cylindrical shell suits form; Outer cylinder body be from top to bottom by four sections diameters from big to small, the cylinder that is uneven in length constitutes, its outward appearance utmost point is similar to " flashlight "; The top of middle cylinder body is the anchor ring structure, has various forms of water inlet eyelets on its anchor ring, anchor ring inner periphery band internal thread; Inner barrel is to be made of segment length's cylindrical shell, and long cylinder body outer wall is provided with external screw thread and sealing ring near the position on cylindrical shell top; Middle cylinder body is inserted in outer cylinder body, and its top anchor ring outer rim places on the positioning table at top of outer cylinder body, and anchor ring inner edge and inner barrel are spirally connected.

Owing to adopt said structure, use the utility model cartridge type floor drain, cooperate lavatory pan again, the shared dewatering horizontal tube of sanitary equipment such as pot sink adopts and insert soil stack more than this layer ground level, just can be people provides the clean kitchen easily of tube, the washroom of one " the salubrious refreshing no any draining of ceiling is done, a transverse tube; sewerage system keeps in repair clear and coherent convenience, needn't disturb lower layer space ".Simultaneously also, kitchen, the washroom that belongs to this cover in the spring layer formula double deck architectural plane provide more convenience (only standpipe passes sitting room or bedroom) for freely being arranged on the sitting room that belongs to this cover or the bedroom.Compared with prior art mainly have the following advantages:

1, the installation of utility model cartridge type floor drain needn't be that cartridge type floor drain itself is reserved the structure aperture specially, is diameter and only need add 100mm with the wideest position external diameter of cartridge type floor drain, and the aperture that the reservation soil stack is worn structural slab gets final product.And other existing floor drain all needs independent location setting-out and reserves the aperture.

Can be socketed on the standpipe as standpipe straight joint when 2, the utility model cartridge type floor drain is installed, easier, itself can be used as the connecting tube of standpipe again the cartridge type floor drain.Other floor drain all relates to being connected of arm and standpipe or transverse tube.

3, the cartridge type floor drain enters lower layer space without any arm when satisfying the ground drain function.And the side-type floor drain that floor drain that other existing double-edged fine-toothed comb level of leaking is installed or double-edged fine-toothed comb are vertically installed all needs to be connected to main with arm independently.Then need do furred ceiling or piping shaft as the hidden arm of need.

4, the occupy-place on the ground of cartridge type floor drain only is to be the anchor ring of axle with the soil stack center line, needn't need independent occupy-place as the floor drain that the existing various double-edged fine-toothed comb levels of leaking are installed, thereby can not influence the layout of other sanitary equipment.
