Abstract

The utility model relates to a siphon trap which comprises a trap, an inlet pipe section and an outlet pipe section, wherein an outlet of the outlet pipe section is arranged upwards, the upper outlet of the outlet pipe section is connected with a downward siphon pipe by the trap, the overflow type of the water flow mode of the trap is changed into a siphon type, the flow speed of water which flows through the trap is accelerated by a siphon function, the flushing intensity is increased, deposits can not deposit at the bottom of the trap, therefore, the trap has no need to be cleaned when used, the needed drainage section can be maintained, a drainage system can keep smooth and is convenient for life, the manpower and the physical resources which are used for maintaining the drainage system are saved, the storage water tank is arranged at the inlet pipe section to increase the water storage of the inlet, consequently, the siphon time is increased, and bottom flushing effect of the trap is further increased.

Description

Siphon trap

Technical field

The utility model relates to a kind of trap, particularly a kind of siphon trap.

Background technology

Trap is one of main accessories of building internal drainage pipeline, when not possessing the person in the structure and being connected with sanitary sewer or other drainage pipes that may produce pernicious gas with the industrial wastewater drop pan, and generally should be in outfall to divide into trap.Its effect is the water column that forms certain altitude within it, and this part water can stop in interior various dusty gas of drainage pipe and the small worm inlet chamber.The drainage principle of trap of the prior art all is by the draining of natural gravity overflow-type, scouring force is less, cause sediment such as solids in the sewage to be deposited on the elbow bottom of trap, thereby reduce water flow section, even often stop up, increase the workload that the user safeguards drainage system, the wasting manpower and material resources causes inconvenience to normal life.

Therefore, need transform, can reduce or eliminate the sediment deposition of trap bottom, keep required draining cross section, not need in the use trap is cleared up existing trap.

The utility model content

In view of this, the purpose of this utility model provides a kind of siphon trap, can reduce or eliminate the sediment deposition of trap bottom, do not need in the use trap is cleared up, keep required draining cross section, drainage system is kept clear, provide amenities for the people, save the man power and material that drainage system is safeguarded.

Siphon trap of the present utility model comprises trap, import pipeline section and outlet pipe section, and the outlet of described outlet pipe section upwards is provided with, and the outlet of outlet pipe section top is connected with downward syphon by elbow.

Further, trap is provided with the import pipeline section, is provided with the storage tank of internal diameter greater than the trap internal diameter between described import pipeline section and the trap.

Further, described elbow pipe bent position is higher than the storage tank top;

Further, described elbow is 180 ° of elbows, and described import pipeline section, outlet pipe section and syphon are all perpendicular to horizontal plane;

Further, be injected into overall structure between described import pipeline section, storage tank, trap, outlet pipe section, elbow and the syphon;

Further, the described storage tank internal diameter 1.5-2.5 that is the trap internal diameter doubly;

Further, the described siphonal length 1.5-2.5 that is outlet pipe section length doubly;

Further, be provided with the blowdown plug bottom the described trap.

The beneficial effects of the utility model are: siphon trap of the present utility model, adopt siphon arrangement, water flow mode in the trap is changed into hydrocone type by overflow-type, pass through siphonage, quicken flow velocity by trap water, dynamics is washed away in increasing, makes the sediment can be in the trap bottom deposit, so does not need in the use trap is cleared up, can keep required draining cross section, drainage system is kept clear, provide amenities for the people, save the man power and material that drainage system is safeguarded; At the import pipeline section storage tank is set, increases inlet water amount, thereby increase the time of siphon, further strengthen the effect of washing away the trap bottom; Each parts of trap are injected into integral body, and are simple and compact for structure, easy for installation; Each pipeline section reduces resistance to water-flow all perpendicular to horizontal plane, is beneficial to the enhancing siphon effect; 180 ° of elbow pipe bent position are higher than the storage tank top, are beneficial to make full use of water tank capacity enhancing siphon effect.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing is the utility model structural representation.

The specific embodiment

Accompanying drawing is the utility model structural representation, as shown in the figure: the present embodiment siphon trap, comprise trap 1, import pipeline section 2 and outlet pipe section 3, trap 1 bottom is provided with blowdown plug 7; The outlet of outlet pipe section 3 upwards is provided with, the outlet of outlet pipe section 3 tops is connected with downward syphon 5 by 180 ° of elbows 4, the length of syphon 5 is 2 times of outlet pipe section 3 length, 180 ° of elbow 4 pipe bent position are higher than storage tank 6 tops, because the effect of syphon 5, when water is full of import and is higher than 180 ° of elbows 4, water is from trap 1 overflow, when water flow to syphon 5, syphon 5 is full of water, produces siphon under action of gravity, can be to the water generates negative pressure in the trap 1, quicken to flow, strengthen scouring effect the bottom; Import pipeline section 2, outlet pipe section 3 and syphon 5 are beneficial to the minimizing resistance to water-flow all perpendicular to horizontal plane, strengthen siphon effect; Be provided with the storage tank 6 of internal diameter between import pipeline section 2 and the trap 1 greater than trap 1 internal diameter, storage tank 6 internal diameters are 2 times of trap 1 internal diameter, increase inlet water amount, thereby increase the time of siphon, further strengthen the effect of washing away the trap bottom;

Be injected into overall structure with the PVC material between the import pipeline section 2 of present embodiment, storage tank 6, trap 1, outlet pipe section 3, elbow 4 and the syphon 5, make simple compact, easy for installation.

Certainly, storage tank 6 internal diameters are not limited to 2 times of trap 1 internal diameter, also can be other multiple numerical value; The length of syphon 5 is not limited between 2 times of the length of water outlet pipeline section, also can be other multiple numerical value, can both reach the purpose of this utility model.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
