Description

Anti-siphon trap is compared in a kind of big water seal

Technical field

This utility model belongs to architectural drainage system trap technical field, particularly to the big water seal of one than anti- Siphon trap.

Background technology

Trap refer to that sanitary apparatus is internal or in fixture drain section configuration a kind of in have the accessory of water seal, Its effect is that the hydrostatic pressing utilizing certain altitude changes to resist drain pipe internal gas pressure, completely cuts off and prevents drain pipe Produced rancid, harmful, fuel gas and small worm etc. are dirty by the entrance indoor such as sanitary apparatus, floor drain Dye environment.Trap can keep certain water, can be by the air in sewerage system and room air Isolation, prevents foul smell from entering indoor.In building iron drain-pipe road system, the traditional standard used is deposited Water curved generally p-shaped and S-shaped tubular structure, be characterized in that cross section of fluid channel amasss equal, the access port area of water seal The most identical.In terms of hydraulics feature, owing to cross section of fluid channel amasss equal, water intake end flow velocity is with water side flow velocity also Equal so that it is there is preferable self-cleaning ability, but this trap reaches capacity peak value at system pressure, or When big flow drainage produces siphonage, bigger trap seal loss can be caused, make trap residue water seal be down to Critical liquid level, it is easy to the phenomenon of drainage pipeline back foul occurs.

Therefore, existing trap exists that water seal is more not enough than negative pressure-pumping performance little, anti-, easily cause drain pipe The defect of road back foul phenomenon.

Summary of the invention

The purpose of this utility model is that the water seal ratio that the existing architectural drainage system trap of solution exists is little, anti- Negative pressure-pumping performance is not enough, easily cause the technical problem of drainage pipeline back foul phenomenon, it is provided that one can be not Increase water seal ratio on the premise of reducing the self-cleaning ability of trap, reduce trap seal loss value, improve anti-negative pressure and take out Absorption and can solve the problem that anti-siphon trap is compared in the big water seal of drainage pipeline back foul phenomenon.

For solving above-mentioned technical problem, the technical solution adopted in the utility model is:

A kind of big water seal is than anti-siphon trap, and it includes trap oral siphon, trap outlet pipe and water seal Bend pipe, wherein: it also includes baffles, baffles is located at the top of water seal bend pipe inner chamber, the one of baffles End is connected with the tube wall of trap oral siphon and water seal elbow inlet junction, the other end of baffles and water The tube wall bowing out water pipe and water seal winding pipe exit junction connects and water seal winding pipe exit is divided into upper and lower two The mouth of a river, is provided with a water inlet in the bottom of the baffles being positioned at trap oral siphon side.

Described water seal bend pipe water side water seal surface area is 1.5～2 times of water seal bend pipe water inlet end water seal surface area.

Owing to this utility model product have employed technique scheme, architectural drainage system trap can be improved Water seal ratio, reducing on the premise of trap seal loss, do not reducing or properly increasing the water velocity of outlet, protecting Hold or improve the self-cleaning ability of trap；When siphonage occurs in big flow drainage, its residue water seal is still Can effectively intercept foul smell；Under conditions of profile size constancy, big water seal is held than anti-siphon trap water seal Amass and can increase more than 15%, the anti-dry ability of trap can be improved, reduce water seal oscillation loss；Transition is even Connect the curved arc structure design of portion's water inlet, not only prevent the blocking of dirt sagging, also reduce resistance to water-flow, Guarantee the reliability that trap uses.Solve the existing trap of architectural drainage system and there is water seal than little, water The envelope degree of depth is not enough, easily cause the defect of drainage pipeline back foul phenomenon, compared with background technology, and this utility model Have on the premise of the self-cleaning ability not reducing trap increase water seal ratio, reduce trap seal loss value, guarantee The trap of water seal depth 50mm is not less than 33mm by remaining water seal after negative pressure-pumping, can improve trap Anti-dry ability, reduction water seal oscillation loss amount and the advantage that can solve the problem that drainage system back foul phenomenon.

Detailed description of the invention

Embodiment 1

As it is shown in figure 1, the big water seal of a kind of S type structure in the present embodiment is than anti-siphon trap, its bag Include trap oral siphon 1, trap outlet pipe 2 and water seal bend pipe 3, wherein: it also includes baffles 4, Baffles 4 is located at the top of water seal bend pipe 3 inner chamber, one end of baffles 4 and trap oral siphon 1 and water The tube wall of envelope bend pipe 3 inlet connection connects, the other end of baffles 4 and trap outlet pipe 2 and water seal The tube wall of bend pipe 3 outlet connection connects and water seal bend pipe 3 outlet is divided into upper and lower two outlets 6,7, It is provided with a water inlet 5 in the bottom of the baffles 4 being positioned at trap oral siphon 1 side.Described water seal bend pipe Water seal surface area in water side is 1.5～2 times of water seal bend pipe water inlet end water seal surface area.

Embodiment 2

As in figure 2 it is shown, the big water seal that the present embodiment is a kind of p-type structure is than anti-siphon trap, it will be real Executing the trap outlet pipe 2 in example 1 from vertically becoming level, remaining structure is identical with embodiment 1.

Operation principle of the present utility model is: during big water seal uses than anti-siphon trap, sewage is from depositing Water bend into water pipe 1 and enters, and part is flowed out by lower outlet 7 after flowing through water seal bend pipe 3；Part by every Water inlet 5 on baffle plate 4, then flows out from upper water-out mouth 6, finally discharges from trap outlet 2.When There is full-section pipe-flow in draining, and when forming siphon, at blow vent 6, baffle plate is higher, when water seal is sucked, because of The water in blow vent 6 region is protected, and when water seal recovers, trap seal loss diminishes.During because siphon occurs, Arrival end liquid level maximum decrease value is 50mm, i.e. H=h, uses traditional structure trap to remain water seal and is: H-h/2=50-50/2=25mm, and use the big water seal than the residue water seal obtained by anti-siphon trap to be: H-h/3=50-50/3=33mm, the lower limit requirement far above 25mm, it is achieved that at water intake end water seal surface area not Increase water seal surface area in water side while change, improve water seal ratio, reduce trap seal loss, play effectively Prevent the effect that siphon is aspirated.

This utility model is designed with foundry method manufacture, it would however also be possible to employ HDPE, PVC and its The materials such as his plastics manufacture other processing technology of molding and manufacture.
