Description
Technical field
Building foul water system is the utility model is related to, is more particularly to used for the drainage pipeline for being connected to sanitary equipment
Ventilating bent-tube.
Background technology
Trap (also known as water trap, trap) is the one kind set inside sanitary apparatus or in fixture drain section
Accessory.Under normal conditions, the water storage that can be kept certain height in trap, it is referred to as water seal.Utilize the hydrostatic pressing of water seal
The air pressure change in drainpipe is resisted, the rancid, pernicious gas in sewerage system and room air can be completely cut off, prevented
Pipeline gas, insect etc. get in.
It is the main reason for causing foul smell in kitchen, toilet that water seal in trap, which is lost in,.Cause one that water seal is failed
Kind main cause is the siphonic effect of fluid.Bathtub draining is diagrammatically illustrated in Fig. 1 and forms siphonic effect.When sanitary equipment exists
In the case of instantaneous a large amount of drainings, trap itself is full of and forms siphon, and after draining terminates, water seal is left due to siphonic effect
Trap.The generation of siphonic effect and the combination of sanitary apparatus and trap, the caliber of drainpipe, length etc. are relevant.
When the sewage of multi-story structure largely discharges, two kinds of air pressure are formed in public drainpipe, are formed above sewage negative
Pressure gas stream, and sewage pressurized air stream formed below.Negative-pressure air-flow produces siphonic effect, and the water storage in trap is extracted out, caused
Water seal is failed.Meanwhile the pressurized air stream of lower section produces back pressure effect due to needing to depressurize, by depositing for low layer resident family sanitary equipment
Water storage push-in in water is curved is indoor.
To solve the above problems, designing antisyphonage pipe, it is a kind of trunnion, typically and atmosphere, for the row of dredging
Air-flow in water system, alleviate negative-pressure air-flow and pressurized air stream in drainage pipeline.When producing negative-pressure air-flow in drainpipe, lead to
Cross antisyphonage pipe and extract air, fill up the air lost in drainpipe.On the other hand, pressurized air stream is discharged via antisyphonage pipe,
Keep the pressure balance of drainage pipeline.The setting of antisyphonage pipe can be effectively prevented from siphonic effect and back pressure effect, prevent from depositing
Water seal during water is curved is lost in.
Antisyphonage pipe can be connected with trap, i.e., the connecting portion between trap and antisyphonage pipe belongs to the composition of trap
Part.Trap keeps ventilating by means of connected antisyphonage pipe, prevents water seal to be lost in.
However, if the junction of antisyphonage pipe and the height of soil pipe or the junction of waste pipe are similar, often
When sewage or waste water reaches overflow status, sewage or waste water can be flowed directly into antisyphonage pipe, cause antisyphonage pipe to lose logical
Gas acts on.Therefore, the connection position of antisyphonage pipe must be positioned at the position highest health being connected with soil pipe or waste pipe
On the flood level of equipment.
Existing bend pipe uses the design of single accessory, causes the height phase of antisyphonage pipe connection position and drainpipe connection position
If above-mentioned requirements are not met.Therefore, contractor needs to set up connection position on existing bend pipe, by the installation of antisyphonage pipe
Position is increased to the top of drainpipe link position.This causes the increase of processing cost and building cost, and spends more peace
ETL estimated time of loading.
Utility model content
The technical problem that the utility model solves is how antisyphonage pipe is conveniently connected to the drainpipe of sanitary equipment
Road, while prevent the sewage in drainpipe from flowing into antisyphonage pipe.
Therefore, the utility model provides a kind of ventilating bent-tube, for being connected to the sewerage system of sanitary equipment, institute
State curved positioned at the ventilation formed with multiple antisyphonage pipe mounting characteristics, the multiple antisyphonage pipe mounting characteristic on ventilating bent-tube
