Multiway floor drain

The utility model relates to a kind of parts of domestic sanitary pipe, particularly can prevent the multichannel floor drain that waste water, foul smell instead overflow.

Washroom in the existing house, the draining mouth of pipe of its wash basin, bathtub all adopt takes back the curved pipeline of shape, and on the return pipe road junction that is provided with on ground floor drain all is housed in the open, its purpose all be smelly for fear of oppositely overflowing, run insect.The former shortcoming is easy obstruction, the smelly weak effect of anti-overflow; Although latter Patent Office of the People's Republic of China discloses " novel counnter attack overflow backwater floor drain " that notification number is CN20652110U on November nineteen ninety 7.This scheme makes when the sewage foul smell instead overflows by increasing the turn one's coat chamber and the ball float of turning one's coat around the conduit that is connected with bucket, and the ball float of turning one's coat is sealed mouth at the bottom of the conduit, reach anti-overflow smelly, run the purpose of insect, and can avoid when line clogging the anti-excessive phenomenon of sewage.But this drain structure can only be contained in respectively separately on the draining mouth of pipe of sanitaryware, like this, both has been not easy to install, and has wasted material again, wastes time and energy during construction.

The purpose of the utility model is to provide a kind of S bend pipe and all other bend pipes of not needing, and can directly connect with the wash basin and the bathtub draining mouth of pipe simultaneously, again can the smelly multichannel floor drain of anti-overflow.

The multichannel floor drain comprises fixed cover, be actively connected on the adjustment cover that has panel on the fixed cover port, be fixed on the chamber of turning one's coat on the fixed cover inwall with sealing density ring, place water service pipe in the chamber of turning one's coat and proportion the anti-ball that overflows less than water, the chamber of turning one's coat is the thin-walled cup of a Spherical Bottom, have spillway hole on its top ring wall, water service pipe outer wall suitable for reading is mutually airtight with the chamber port inner wall of turning one's coat; The anti-ball that overflows is positioned at mouth at the bottom of the water service pipe, and its diameter is between turning one's coat between chamber internal diameter and the water service pipe external diameter, is positioned at fixed cover on the sidewall of the chamber port of turning one's coat to have 2 inlet openings, and the base that is connected with blow-off pipe is housed on the mouth at the bottom of the fixed cover.

The utility model will be further described below in conjunction with embodiment shown in the drawings.

Fig. 1 is a structural representation of the present utility model.

See Fig. 1, the multichannel floor drain is by fixed cover 3, is threaded in the adjustment cover 2 on the fixed cover 3, is contained in the chamber 9 of turning one's coat on fixed cover 3 inwalls, places water service pipe 8 and the anti-base 11 that overflows ball 10 and be contained in 3 end of fixed cover mouth in the chamber 9 of turning one's coat to form.

There is shoulder protruding on fixed cover 3 lower inner wall; The prominent internal diameter of shoulder matches with the chamber 9 port outside diameter sizes of turning one's coat; Fixed cover 3 has the inlet opening 4 of two symmetries at the protruding upper wall of shoulder, is shaped on internal thread on the inlet opening, and it can directly be received on the draining mouth of pipe of wash basin and bathtub.

Adjust on cover 2 ports removable panel 1 but is housed, be shaped on the grid hole on the panel 1.

The chamber 9 of turning one's coat is the thin-walled cup of a Spherical Bottom, and its outer wall suitable for reading has groove, and rubber seal 5 is housed on the groove, and the chamber 9 of turning one's coat closely cooperates by sealing ring 5 and the protruding inwall of fixed cover 3 shoulders; Turn one's coat and have equally distributed spillway hole 13 on the 9 top ring walls of chamber.Be equipped with screen 14 on its port surface.

Water service pipe 8 is suitable for reading to be the flange of flare, and the port inner edge is mutually close its flange outer rim and the chamber 9 of turning one's coat joins.The anti-ball 10 that overflows is the butterfly ball of a proportion less than water, and its diameter is bigger than water service pipe 10 external diameters, and chamber 9 internal diameters are little than turning one's coat.

Base 11 takes the shape of the letter U, and has the sewage draining exit 12 that is connected with blow-off pipe on its sidewall, and sewage draining exit also can be opened in base 11 bottoms.Base 11 is fixed on 3 end of the fixed cover mouth outer wall by clamp ring 6 and O-ring seals 7.

During use, the water with wash basin or bathtub on the ground enters water service pipe 8 after filtration, and Spherical Bottom, the spillway hole 13 in the chamber 9 of directly turning one's coat again flow into base 11, enter water return pipeline and emit.

When the water of outside flows when clean gradually, in the chamber 9 of turning one's coat, can keep the water that highly equates with spillway hole 13; This resident water can float the anti-ball 10 that overflows, and makes butterfly face and water service pipe 8 driving fits, plays water seal contacts driving fit with machinery two seals effect, has avoided foul smell and water worm to overflow, and can save the water bending pipe simultaneously.

Obviously, the utlity model has simple in structure, labor and material saving, construction, the advantage such as easy to maintenance; Be applicable on the pipeline that is installed in the civil building toilet.
