Abstract

The utility model relates to an anti-odor draining valve and a corresponding floor drain, which aims to solve the problem that as the conventional water seals can not effectively seal the sewer after the water is dried, the indoor air frequently smells unbearably odorous. The anti-odor draining valve includes an outer pipe, a core pipe, a gland and a spiral spring, wherein the core pipe is fixed at the center of the outer pipe; an inner annular platform is arranged at the bottom of the core pipe; the gland includes a gland body and a core column; the spiral spring is sleeved on the core column, the lower end of the spiral spring is pressed on the inner annular platform, and the upper end of the spiral spring is propped against the lower surface of a screw head of a screw at the top of the core column; all the core column, the spiral spring and the screw are arranged in the core pipe, and can vertically move in the core pipe; and the outer diameter of the gland body is greater than the inner diameter of the outer pipe. The utility model also relates to the floor drain including the anti-odor draining valve. The utility model has the advantages that the structure is simple, pollution discharge is smooth, and the sewer can be sealed when no water is present; and the anti-odor draining valve and the corresponding floor drain are suitable for all the buildings in need of sewage drainage.

Description

Deodorization drain valve and corresponding floor drain

Technical field

The utility model relates to a kind of sewer unidirectional blocking mechanism, particularly a kind of deodorization drain valve and corresponding floor drain.

Background technology

Floor drain, toilet, bathtub, vegetable sink, washing basin be all to the sewer blowdown in the various building, and sewer communicates with sewage reservoir or septic tank.As not adopting suitable sealing measure, the gas with foreign flavor such as foul smell in sewage reservoir or the septic tank must on scurry in the resident family, influence IAQ (indoor air quality).

Usually the practice is that U-shaped water seal or other water seals are set between floor drain, toilet, bathtub, vegetable sink or washing basin and sewer.But after the killing in the water seal, the gas with foreign flavor in sewage reservoir or the septic tank still can be scurried in the resident family.

After the people who travels outdoors goes home, often finding that room air is extremely stagnant, is that the gas with foreign flavor in sewage reservoir or the septic tank is scurried into resident house because water has been done in the water seal mostly.Dry area shows particularly evident this point in the north.People press for a kind of dry sewer unidirectional blocking mechanism.

The utility model content

The technical problems to be solved in the utility model is how to fill up the above-mentioned blank of prior art, and a kind of deodorization drain valve and corresponding floor drain are provided.

For solving the problems of the technologies described above, the utility model deodorization drain valve comprises outer tube, core pipe, capping and helical spring, its core pipe is fixed on outer tube hub, ring platform in core pipe bottom is provided with, described capping comprises lid and stem stem, described helical spring is enclosed within on the stem stem, encircle on the platform in its lower end is pressed in, its upper end withstands on the ailhead soffit of screw at stem stem top, described stem stem, helical spring, screw all are arranged in the core pipe, and can move up and down along the core pipe, described lid external diameter greater than with outer tube end opening internal diameter.

During use, this deodorization drain valve is contained in the bottom opening of floor drain, washing basin, vegetable sink or bathtub, makes its stem stem get final product (when washing basin, vegetable sink or bathtub water storage, need join the water blockoff plug in addition) straight up.

After washing basin, vegetable sink or excess surface water, hydraulic action overcomes helical spring elastic force on the lid of capping, and lid moves down, and sewage enters sewer; During no ponding, under helical spring bounce-back, the lid of capping is sealed the outer tube end opening, and the sewer and the interior space is isolated.

So design, because be not to seal close sewer by the water source, even the house is unoccupied for a long time, room air is still more pure and fresh.

As optimization, described core pipe top also is provided with a shutoff plug.So design, helical spring does not contact with water substantially, and is not perishable.

As optimization, described core pipe is fixed on the outer tube by three connecting rods, and above-mentioned connecting rod is radial even distribution.So design, simple in structure, mechanical strength good.

As optimization, described outside pipe is provided with gas thread (supporting floor drain, washing basin and vegetable sink also should be provided with the respective tube screw thread with this deodorization drain valve), and the outer tube top also is provided with the outer shroud platform.So design is convenient to install on the one hand, and pipe thread seal is effective on the other hand.

The utility model floor drain comprises floor drain seat and screen, and described floor drain seat center has through hole, and described screen embeds the floor drain seat, and is positioned at the through hole top, is provided with aforementioned deodorization drain valve in the described through hole.So design is simple in structure, easy for installation.

As optimization, also be provided with sieve plate between described screen and the deodorization drain valve, sieve aperture gathers on this sieve plate.So design can filter out impurities, and prevents that foreign material from blocking capping, makes it can't normally seal sewer.。

As optimization, described screen is rounded, its soffit is provided with the grab of two outside symmetries, described floor drain seat is provided with corresponding circular caulking groove, have annular groove on the inside wall of this circle caulking groove below, have two relative breach on the interlayer between this circle caulking groove and the annular groove, this breach is corresponding with described grab.So design is put into circular caulking groove with screen, makes the corresponding breach of its grab, rotates suitable angle then, screen can be stuck on the floor drain seat.

That the utility model deodorization drain valve and corresponding floor drain have is simple in structure, blowdown is smooth and easy, can seal sewer under anhydrous state advantage is applicable to the various buildings that need sewer.
