Description

Novel pipeline odor-proof valve

Technical Field

The utility model belongs to the technical field of drainage system technique and specifically relates to a dedicated sewer pipe product.

Background

Along with the continuous improvement of the requirements of people on living quality and the increasing requirements on living environment, the pipeline odor-proof valve plays an important role as a main drainage component which is necessary for connecting a sewer pipe on a kitchen, a bathroom and a balcony. Because the drainage pipeline is directly communicated with the main sewer pipeline, when the main sewer pipeline is blocked, reverse surge can occur; the existing pipeline odor-proof valve is easy to generate back water and smell due to low sealing property, and snake, insect, rat and ant often invade from a sewer, so that inconvenience is brought to life of people; the existing pipeline odor-proof valve generally uses a U-shaped or S-shaped water storage pipe, because the length of an annular water tank is too long, the gap between the inner wall of the annular water tank and the side wall of a reversing cylinder is too narrow, and because a related closing part is arranged in a sewage circulation passage, hairs are easily hung on the sewage circulation passage, so that the drainage speed is influenced, and the blockage is easy.

In order to solve the problem, the utility model discloses a novel deodorant valve, small, simple structure, sealing performance are good, can be used to the drainage of family's sewer line, and economic nature is good, market prospect is wide.

Disclosure of Invention

The utility model discloses an actively the effect as follows: the utility model provides a novel pipeline odor-resistant valve, the size is little, the mountable is at the lower mouth of a river of kitchen sink, bathroom wash-basin, and simple structure is reliable, need not the water seal, does not produce the noise during the drainage, can effectively deodorant, prevent kicking and prevent four pests, its leakproofness is good, and drainage effect is good, difficult jam and exempt from the clearance.

The utility model discloses a solve current problem, the technical scheme who adopts as follows:

2. The integral size of the odor-proof valve is small, and the odor-proof valve can be flexibly applied to different installation spaces.

3. The odor-proof valve is connected with the water inlet pipe and has two thread specifications, and the odor-proof valve is suitable for different water inlet pipe thread specifications at home and abroad.

4. The silica gel sleeve is arranged on the positioning pin of the silica gel sleeve seat, and the structure is simple and reliable; when water is drained, the silica gel sleeve is deformed by the pressure of water flow to form a flow passage for discharging sewage; when no water exists, the silica gel sleeve automatically resets without additionally arranging a water seal structure, and is matched with the rubber sleeve seat, so that sewage can be prevented from overflowing, insects and the like from entering the room, the problem of bacterial breeding is effectively avoided, and the effects of deodorization, no noise, no blockage and no cleaning are achieved.

5. The water outlet surface of the silica gel sleeve can be designed to be 40-60 degrees, water flow is conveniently pushed open during sewage discharge, and deformation resistance of the silica gel sleeve is reduced.
