Description

Anti-overflow pipe fitting of drainage system

Technical Field

The utility model relates to a water supply and drainage engineering technical field, concretely relates to drainage system prevents returning excessive pipe fitting

Background

The improvement is open, the urbanization construction of China has drawn attention, the living standard of people is continuously improved, the housing condition is greatly improved, and the quota of the water consumption per capita is gradually increased. The water supply and drainage system is one of the important matching system components in engineering construction, and the advancement of the design technology directly influences the quality of the engineering construction and the use experience of later-stage users. Taking a kitchen drainage system as an example, the current conventional kitchen drainage system is that a washing basin drainage pipe is connected to a trap and then connected to a main drainage vertical pipe; in the method, the phenomenon of indoor water return of a low floor is basically avoided because the main drainage vertical pipe is relatively unobstructed in years before completion and delivery of the project or when users are few. However, as time goes on, when the pipe wall of the main drainage vertical pipe is gradually adhered by oil stains and the area of the cross section of the water flow becomes smaller, and the upstairs residents wash basins discharge large garbage impurities, the phenomenon of blocking the transverse drainage pipe is easy to occur. At the moment, as upstairs residents do not know the blockage of the drainage transverse pipeline and continue to drain water, sewage is gathered in the main pipeline and rises to overflow into the resident rooms at the bottom floors communicated with the main sewer pipeline; when no people are in the room and cannot be found in time, a large amount of sewage enters the room; not only causes economic loss, but also causes contradiction between upstairs and downstairs residents due to poor solution of the problems, and is not favorable for social harmony and stability. Sometimes, even if the property is dredged, the property is still blocked in the later period, so that residents on low floors feel ugly; therefore, how to thoroughly solve the problem of sewage overflow of the low floor is an urgent problem to be solved.

in the figure, an upper bell and spigot 1, a buoy top cover 2, a buoy 3, a floating ball 4, a lower bell and spigot 5, a trap 6, a vertical drainage pipe 7, a wash basin 8 and a horizontal drainage pipe 9.

Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in figure 1, the overflow-preventing pipe fitting for the drainage system is made of hard polyvinyl chloride (PVC-U) materials and comprises an upper bell and spigot 1, a floating pontoon top cover 2, a floating pontoon 3, a floating ball 4 and a lower bell and spigot 5. The outer diameter of the floating cylinder 3 is phi 110mm, the height is 200mm, the water inlet caliber at the upper end of the floating cylinder 3 is phi 50mm, the water outlet caliber at the lower end of the floating cylinder is phi 50mm, and the outer diameter of the floating ball 4 is phi 75 mm; a gap of 25mm is reserved between the floating ball 4 and the floating pontoon 3, and the floating ball 4 can float freely up and down in the floating pontoon 3. Adopt screw thread rubber ring sealing connection between flotation pontoon top cap 2 and the flotation pontoon 3, be convenient for install and dismantle and clean.

As shown in the attached figures 2-3, when the drainage pipeline is installed, firstly, the upper opening of the trap 6 is inserted into the lower bell and spigot 5 of the buoy 3, then the water outlet pipe of the washing basin 8 is inserted into the upper bell and spigot of the buoy 3, the connection is sealed by a rubber ring, and the water-closing test can be used after no leakage is detected. The most critical step for determining the use effect of the anti-overflow pipe fitting is to ensure the integrity of the installation tightness of the pipe fitting; therefore, during installation, whether the floating ball 4 in the floating barrel 3 is a sphere or not is firstly checked, and whether tight combination is formed between the floating ball 4 and the water inlet of the floating barrel top cover 2 is checked. The detection mode is as follows: invert the flotation pontoon top cap 2, put the floater 4 on, the 2 water inlets of flotation pontoon top cap are just in time blocked up to floater 4, press fixed floater 4 gently with the hand, water to the floater 4 again, see whether there is water to flow from the 2 socket joint water inlets of flotation pontoon top cap of inversion, if leak then be nonconforming product, need change. In addition, when the upper bell and spigot of the floating barrel 3 is connected with a drain pipe of a washing basin 8, the lower bell and spigot is connected with a trap 6, and the floating barrel top cover 2 is connected with the floating barrel 3, the direction of the pipe orifice is vertical to the bell and spigot when the pipe orifice is connected with the bell and spigot, the force is moderate, the threads are fastened and loosened properly, and the sealing rubber ring is not deviated; therefore, the sealing performance of the installation of the pipe fitting can be ensured to the maximum extent, and the using effect of the anti-overflow pipe fitting is ensured.

As shown in figure 2, when the horizontal drainage pipe 9 is unobstructed and the washing basin 8 begins to drain water, the floating ball 4 in the buoy 3 floats upwards along with the rise of the water level in the buoy 3, the water outlet of the buoy 3 is opened, and sewage is smoothly discharged through the water inlet and the water outlet of the buoy 3. When the horizontal drainage pipe is blocked, as shown in fig. 3, the water level in the vertical drainage pipe 7 gradually rises, sewage begins to flow backwards indoors, the water level in the buoy 3 and the floating ball 4 also rise along with the water level, when the floating ball 4 rises to the water inlet on the buoy top cover 2, the water inlet on the buoy top cover 2 is just blocked, and the water level in the buoy 3 stops rising; along with the water level in the vertical drainage pipe 7 is higher and higher, the height difference between the vertical drainage pipe and the floating ball 4 is larger and larger, the vertical upward water pressure borne by the floating ball 4 is larger and larger, the water inlet of the floating barrel top cover 2 is more tightly blocked by the floating ball, and the sewage is effectively prevented from overflowing indoors.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
