Abstract
The utility model discloses a sewer port sealing device, which comprises an inner pipe and an outer pipe; a flange or a conic pipe is provided at upper end of the outer pipe, at least one water discharge port is provided at the side of the outer pipe, a sealing pipe bottom is provided at lower end of the outer pipe; the inner pipe is fixed in the outer pipe, a flange is arranged at upper end of the inner pipe, a contact surface between the flange and the outer pipe is sealed, a water outlet at lower end of the inner pipe is lower than the water discharge port of the outer pipe. The device can isolate air the room from gas in the sewer, and prevent various harmful gases from entering the room; water outlet of the device is large and is seldom blocked; water sealing of the device is very deep, but the capacity is small, and the device is easy for disinfection treatment; the device is inserted in water outlet in floor drain iron bowl, changing the structure is unnecessary, installation and construction of specialized persons are unnecessary, plug-and-use is realized; the device has rational design, simple structure, convenient production and cheap cost, and is suitable for sealing of most of sewer ports.
Description
Technical field
The utility model relates to a kind of sewer mouth sealing device.
Background technology
A lot of houses are because sewer mouth seal approach is bad, gas in room air and the sewer can not be isolated fully, the sewer of " U " shape tubular structure more particularly is not set, gas in room air and the sewer is in actual connected state, various viruses and pernicious gas are easy to pour in down a chimney into indoor in the sewer, pollute.The survey report of WHO shows, concentrated the breaking out of big garden SARS epidemic washed in a pan in Hong Kong, be exactly because this sub-district dwelling house sewer mouth poorly sealed due to.
The utility model content
The purpose of this utility model is that to design a kind of be the sewer mouth sealing device that main part is formed by interior pipe, outer tube in order to overcome above-mentioned deficiency.This device can prevent effectively that various viruses and pernicious gas from polluting indoor environment.
The purpose of this utility model is achieved in that
A kind of sewer mouth sealing device, this device is made up of interior pipe, outer tube; The outer tube upper end is provided with flange or Taper Pipe, and its side is provided with at least one outfall, and its lower end is provided with at the bottom of the pipe of sealing; Interior pipe is loaded in the outer tube, and interior pipe upper end is provided with flange, the mating face sealing of its flange and outer tube, and interior pipe lower end delivery port is lower than the outer tube outfall.
The interior tubular axis of restriction is set on the outer tube wall is provided with the pillar that limits its axial location to the strong point of the projection of position or in interior pipe lower end.
Owing to be provided with by interior pipe, outer tube structure in this sewer mouth sealing device, can be with the gas barrier in room air and the sewer, prevent that various viruses and pernicious gas are poured in down a chimney into indoor in the sewer, pollute; The delivery port of this device is bigger, is difficult for stopping up; The water seal of this device is very dark, but capacity is little, is easy to disinfect; This device directly is inserted in the delivery port of floor drain iron bowl, need not change existing structure, need not professional's installation, has realized plug and play; This device is reasonable in design, simple in structure, simple for production, with low cost, is applicable to the sealing of most sewer mouths.
Description of drawings
Fig. 1 is the utility model embodiment schematic diagram;
Fig. 2 is a sewer mouth sealing device structural representation;
Fig. 3 is interior pipe front view;
Fig. 4 is the upward view of Fig. 3;
Fig. 5 is the front view of outer tube;
Fig. 6 is the lateral view of Fig. 5.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Present embodiment is made up of sewer pipe 1, interior pipe 2, outer tube 3, iron bowl 4, grate net 5, floor 6 and seal 7.The inlet of sewer is equipped with the iron bowl, is provided with seal between outer tube and iron bowl.Referring to Fig. 1.
The upper end of outer tube is made as Taper Pipe 8, and the upper end of interior pipe is provided with flange 9.Referring to Fig. 2.
The lower end of outer tube is provided with the pipe end 10.Be connecting band 11 between two delivery ports, the lower end of outer tube is provided with two delivery ports 12, referring to Fig. 5, Fig. 6.
In pipe upper end be provided with flange 9, and with the inwall interference fit of outer tube, in case leak-stopping gas; Interior pipe lower end is provided with pillar 13, in case interior pipe sinks to stopping up delivery port.Referring to Fig. 3, Fig. 4.
Interior pipe and outer tube all can wholely be made.In between pipe, interior pipe delivery port and outer tube bottom, inner and outer pipes and the water flowing area of outer tube delivery port should mate, reduce obstruction as far as possible.
The utility model can make sewage through grate net, outer tube, interior pipe, flow into outer tube the bottom again the passage through being positioned between outer tube, pipe flow into sewer.Because the sealing function of outer tube lower end water layer has cut off the passage in the gas inlet chamber in the sewer, guarantee in interior various viruses of sewer and the unlikely inlet chamber of pernicious gas.
