The anti-dry water-sealing stinking-proof of large flow anti-backflowing can the safe floor drain of flood dischargeTechnical field
The anti-dry water-sealing stinking-proof of the large flow anti-backflowing of the present invention can the safe floor drain of flood discharge, belongs to floor drain technical field.
Background technology
Floor drain is the important interface that connects sewer pipe system and flooring, and as the vitals of house draining system, its performance quality directly affects the quality of room air, and even the healthy living quality of the people to premises is all extremely important.
Mainly contain in the market a few class construction drainage floor drains such as common hydrolock, mechanically sealed formula and float valve deodorization formula, and the shortcoming that these several classes have some to be difficult to overcome is completely exemplified below:
Common hydrolock: water seal height is not up to standard, water seal is easily dry, cannot anti-backflowing, very easily stop up and also drainage speed slow.
Mechanical close formula: bad sealing is close, parts easily damage and are aging, reliability extreme difference, life of product is not long.
Float valve deodorization formula: bad sealing is close, parts easily damage and lost efficacy, and complex structure is difficult to maintenance.
The drainage speed of above-mentioned several floor drains is all little, does not far reach the speed of the 1L/s of national Specification, runs into forget to turn off the tap or when water pipe explosion, ponding is serious; Odor-resistant result is bad; Do not have anti-backflowing structure or anti-backflowing unreliable, affect drainage speed; And they all do not have the utensil drainage joint that switching performance is good, can not meet the drainage requirement of people's daily life.

The present invention compared with prior art has following beneficial effect.
1, powerful and Sizes, the employing of novelty of the present invention multi-ball type anti-backflowing system, compared with single ball formula anti-backflowing, reduced product height, can apply in reality.
2, reliable anti-backflowing and do not affect drainage speed, the present invention can effectively control the position of anti-backflowing ball in drainage procedure, anti-backflowing ball only can rotate or slightly beat at anti-backflowing cavity bottom, can not affect drainage speed, owing to there being guide strip restriction, anti-backflowing ball can not stop up draining, in the time that sewage instead overflows, can float in time and block water circular hole again, and while reaching normal use, displacement is large, the unusual time can flood discharge and the reliably effect of anti-backflowing of energy.
3, flow is large, is all provided with flow-guiding structure in the present invention on water seal cover, main casing, lid, makes current more smooth and easy, has increased flow; In addition, the sunk type that the top board of lid forms lower than sidewall is guided pond, has increased the inflow of anti-backflowing cavity, overcome the little problem of mistake water circular hole inflow on lid, further increase flow of the present invention, made more than normal displacement of the present invention reaches 1L/s, to meet national standard.
4, anti-dry property is good, in the present invention, the height of water seal has reached 50mm, meet national standard, the water seal height of general floor drain on field, supermarket far away, water seal can be kept more than 30 days, in addition, in the present invention, be also provided with double-deck grate, and the void shape that makes them is identical and the setting of staggering each other, like this, the water in water seal is not directly exposed in the external world, has effectively delayed the evaporation rate of water seal, can stop to greatest extent the dry inefficacy of water seal, water seal can both be kept more than 60 days under various environment.
5, odor-resistant result is good, has adopted high water seal in the present invention, and has the design that extends dried-up time, and odor-resistant result is good and reliable.
6, flood discharge is effective, in actual use, run into and forget to turn off the tap or when water pipe explosion causes the situation of a large amount of water outlets, the safe floor drain of deodorization of the present invention coordinates and can produce siphonage with sewer pipe, more accelerate the flow velocity of current, ensured the indoor ponding that do not occur.
7, easy for installation; in the present invention, used unit is all applicable to producing in enormous quantities; and easy for installation; do not need professional and instrument; all parts convenient disassembly; easily clean or change; in addition, the present invention is also with protective cover, in the time of construction; only main housing portion first need to be fixed; cover over cap, while waiting floor to be taped against, the more inner part such as anti-backflowing cavity, water seal cover is packed into; prevented the damage of inner body in construction, protective cover can ensure that main casing inside does not sustain damage in construction.
8, in the present invention, be connected with utensil dewatering installation, can adapt to the gutter of different size diameter, and connect reliably, good airproof performance, draining is smooth and easy, can not produce the situation that spills into ground.
9, the present invention can replace with the part resting on the ground concealedly easily, in the situation that performance is constant, can make a series of products of various outward appearances.

By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from aim of the present invention, makes various variations.
In above-mentioned several embodiment, be bonding between the outfall of main casing bottom and the gutter of sewer, and the gutter of sewer inserts in the outfall bottom main casing.In addition, the top of main casing is all equipped with over cap, is threaded connection, or connects by buckle between described over cap and main casing.
The course of work of the present invention is:
As shown in Figure 1, ground sewage enters in main casing through water inlet grate surrounding, then by being pooled to anti-backflowing cavity top after water seal, under the pressure-acting of current, enters in sewer pipe.In the time forgetting to turn off the tap or water pipe explosion causes ground to have a large amount of ponding, can in anti-backflowing cavity, form siphonage especially, further accelerate the flow velocity of current, ensure that indoor ponding enters sewer pipe very soon.The present invention adopts the most reliable water-sealing stinking-proof principle, and the 50mm that its water seal height is up to state standards can effectively prevent that foul smell, winged insect and the germ etc. in sewer pipe from entering indoor.Double-deck grate structure in the present invention not only can, to impurity slightly large in sewage as hair etc. filters collection, to prevent these impurity obstruction dewatering installation and sewer pipes, can also extend the dried-up time of water seal.Each flow-guiding structure of water seal place has been accelerated the flow velocity of current, has increased displacement, and the sunk type guiding pond of anti-backflowing cavity top has further increased displacement of the present invention.Multi-ball type anti-backflowing structure makes anti-backflowing function more reliable in reducing product height.Need to when utensil gutter is connected, can use the product of the present invention with utensil dewatering installation, can easily connect reliably.In addition, can be concealed by earth's surface of the present invention partial design, increase aesthetic property.
