Description

Odour seal

A kind of floor drain that is used for the constructure ground draining belongs to construction drainage accessory field.

In the kitchen of building, the ground located such as bathroom, washroom need install floor drain to be used to drain the floor drain that ground sewage and Xia Shui, tradition use be " button clock-type " floor drain, it has water seal to prevent that foul smell from overflowing, suitable for reading have bamboo comb to prevent the foreign material blocking pipeline, simple in structure, is widely used.But " button clock-type " floor drain has following deficiency:

1, cast housing and cement installing hole can produce the space between the two owing to expand with heat and contract with cold, and occur the infiltration of water easily.

When 2, floor drain being installed, the stratum wipe one's face highly wayward to form drainage grade, construction inconvenience.

3, water seal height is not enough, does not reach the standard of national draining standard.

4, the silt particle during draining stops up groove easily and becomes silted up deadly, causes impeded drainage.

The purpose of this utility model provides a kind of floor drain of new construction, overcomes above deficiency, makes its waterproofing work that can be easy to do, and stops seepage; Be convenient to construction, make drainage grade easily; Water seal height reaches national draining codes and standards; Be difficult for stopping up the draining smoothness.

Used technical scheme is:

1, shell 1 is a hollow sleeve shape, and the anti-hydrofoil ring 7 of outside protrusion is arranged on its top excircle, and the bottom surface 8 of wing ring 7 is back taper, is convenient to do waterproofing work during construction, stops the seepage between cast housing and the concrete pedestal.The inner chamber of shell has the internal thread 9 with 2 one-tenth adjustable connections of adjustment disk, and vertical screw thread delivery port 10 is arranged at its bottom, and this delivery port also can be horizontal water outlet, is positioned on the side periphery.

2, adjustment disk 2 is the hollow ring shape, its screw thread top of matching with shell 1 has male end plane 11 to be supported on the plane, upward top of shell 1, its top has female end plane 12 to be used for supporting construction cover 6, and ring has ring limit 13 protruding upward to be used for supporting to return water drum 3 in it.But the adjustable diameter and screw adjusting filter cartridge was made drainage grade easily apart from the height of wiping one's face of surface layer when the effect of adjustment disk was construction.

3, by returning water drum 3 and megaphone 4 is formed the water seal tube.It is cup-shaped to return water drum 3, and the end is arranged at the bottom, and the wing limit 14 of the band groove of outside protrusion is arranged at top, and there is circumferential delivery port 15 side, all ladder platforms 16 in having near the upper edge of delivery port 15; Megaphone 4 is up big and down small hollow cylinder, flare suitable for reading, and its limit, outer 17 is bearing on the interior ladder platform 16 that returns water drum 3.The spacing of returning the base of the bottom of delivery port 15 of water drum 3 and megaphone 4 is the height of floor drain water seal.The advantage one of this structure is the water seal height that can guarantee 50mm, reaches national draining code requirement, the 2nd, and this returns water drum and can extract and clean.

4, cover 6 by bamboo comb 5 and construction and form two-layer filter cartridge, bamboo comb 5 is the inversed taper platform bowl-type, upper and lower opening, filter bores 18 is arranged on bottom surface and the inverted cone surface, the top has evagination wing plane of a loop 19 to be supported on the wing limit 14 of returning water drum, construction covers 6 for the disk or the square plate of a plurality of filter bores 20 are arranged, and is supported on the last female end face 12 of adjustment disk 2.The filter cartridge structure of this two-layer filtration is convenient to remove the filtration foreign material.

Above-mentioned each member available metal or plastics are made.The best with the material scheme is: housing 1, adjustment disk 2, construction covers 6 usefulness and are cast and make; Return water drum 3, megaphone 4, double-edged fine-toothed comb 5 is made of plastic.

The drain structure that the utility model provides is reasonable, and it has overcome the deficiency that " button clock-type " floor drain exists: stopped the seepage between cast housing and the cement floor, can guarantee to wipe one's face drainage grade; Can reach the water seal height of national draining code requirement, its water seal tube is convenient to take out and is cleaned, and its two-layer filter cartridge is easy to remove foreign material.Floor drain of the present utility model has is convenient to construction, easy to use, draining smoothness, the advantage of dependable performance.
