Description

Sealing bell-jar floor drain

Technical field

The utility model relates to the plumbing product, specifically, is a kind of sealing bell-jar floor drain.

Background technology

Floor drain is not only the land drainage device on the simple meaning, and is indoor requisite sealing device.The tradition water seal type floor drain is the bell-jar structure, as shown in Figure 5, namely is buckled on the sewer pipe mouth with a button bowl (bell jar), builds " U " type trap, and then reaches the purpose of sealing, is also referred to as " water seal ".If but the time is permanent, when water is dried-up, will be as shown in Figure 6, the gas in the drainage pipe get around the button bowl go to indoor.The national standard of China's floor drain water seal height is 50mm, but most water-seal floor drain water seal heights only have 10-20mm in the market, and is very easily dry; Even water seal is deepened to 50mm, delay only the time of not back foul in several days flavor; And water seal is darker, and not only setting height(from bottom) is limited, and inwall to adhere to foul also more, can't clear up; Moreover at cloudy day or the weather of blowing, air pressure constantly changes, and the malleation in the pipeline can cause button bowl come-up, and foul smell will overflow from water; And the negative pressure in the pipeline can be destroyed the water seal suction, and pipeline loses barrier, and foul smell also can overflow into indoor.Therefore, how to guarantee is having under water and the anhydrous state, all can make floor drain keep sufficient sealing effectiveness, is a difficult problem to be solved.

Summary of the invention

The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of sealing bell-jar floor drain to be provided.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of sealing bell-jar floor drain, its floor drain body are provided with the bell jar of doing sealing that links to each other with double-edged fine-toothed comb, and described bell jar and described double-edged fine-toothed comb are provided with the closing device that described bell jar is moved up and down for being flexibly connected at described double-edged fine-toothed comb.

As further improvement of the utility model, described closing device is double-screw bolt, and the rotation double-screw bolt can make described bell jar move up and down along double-screw bolt.

As further improvement of the utility model, described double-screw bolt is positioned at the centre of described double-edged fine-toothed comb; Described double-edged fine-toothed comb is relative fixing with described floor drain body by bayonet socket or screw thread.

As further improvement of the utility model, described double-edged fine-toothed comb also is provided with guide rod and links to each other with described bell jar.

As further improvement of the utility model, described closing device is a flip-over type switch.

As further improvement of the utility model, the joint of described bell jar and described floor drain body is provided with sealing mat.

Adopt the good effect of the utility model sealing bell-jar floor drain to be:,

Let out under sewage is arranged when filling up " U " type trap, the floor drain body plays the effect of " water seal " with bell jar, has blocked the foul smell of sewer; Permanent when the time, when the sewage of water crook dries up, start the closing device on the double-edged fine-toothed comb, allow bell jar descend and contact with the floor drain body, play the effect of shutoff gas overflowing by the sealing mat of joint.Therefore no matter the utility model sealing bell-jar floor drain is having the effect that can both play sealing in water or the anhydrous situation.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Embodiment 1:

As depicted in figs. 1 and 2, the utility model sealing bell-jar floor drain, the closing device that is located on the double-edged fine-toothed comb 2 is a flip-over type switch 4.When water seal among Fig. 17 was intact, bell jar 3 is attached on the double-edged fine-toothed comb 2 and is integrated, and was the same with traditional hydrolock bell jar floor drain, formed the water seal effect by bell jar 3 and floor drain body 1 and blocked overflowing of sewer gas 6; And when the water seal 7 among Fig. 2 disappears, can start flip-over type switch 4, and promptly allow bell jar 3 drop to floor drain body 1 and contact, rely on the sealing mat 5 that is located on the bell jar 3 to play the effect of further stopping up sewer gas 6 to overflow.

Embodiment 2:

Be that with embodiment 1 difference part closing device is double-screw bolt 9, bell jar 3 is provided with the screw thread that cooperates with double-screw bolt 9, and rotation double-screw bolt 9 just can make bell jar 3 move up and down along double-screw bolt 4; Double-screw bolt 9 generally is positioned at the centre of double-edged fine-toothed comb 2, and double-edged fine-toothed comb 2 is motionless with floor drain body 1 relative permanent position by bayonet socket or screw thread, can not drive double-edged fine-toothed comb 2 like this when rotation double-screw bolt 9 and rotate together; Also be provided with guide rod 8 on the double-edged fine-toothed comb 2 and be connected with bell jar 3, so that bell jar 3 does not train off when moving up and down smoothly.When water seal among Fig. 37 was intact, bell jar 3 also was integrated with double-edged fine-toothed comb 2, formed water seal and blocked overflowing of sewer gas 6; When the water seal among Fig. 4 disappeared, rotation double-screw bolt 9 can make bell jar 3 be down to contact with floor drain body 1 and compress, and relied on sealing mat 5 to play the effect that stops that sewer gas 6 overflows.

At last, it should be noted that above what enumerate only is 2 kinds of specific embodiments of the present utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
