Abstract

The utility model relates to a non-return device of a sewer, which is composed of a water storing barrel, a flow guiding pipe, a non-return plug and a casing, wherein, an overflow hole is arranged on the water storing barrel, the flow guiding pipe extends into the water storing barrel, and the non-return plug is arranged on the lower end of the flow guiding pipe. The structure of the utility model is formed into an S-shaped sewer channel which can reliably prevent water and air in the sewer from returning upwards, and the non-return capability is strong. The utility model is especially suitable for hanging type face washing pools, basins, urinals and water discharging holes of floor drains.

Description

Non-return device of sewer

The utility model subordinate water channel stops the counter-flow water device of air.

At present existing non-return device for sewer is to adopt ∽ shape bend pipe to stop to return water, gas, and non-return ability when returning water, gas on stronger is arranged in its shortcoming sewer, and can not stop and return water.

The purpose of this utility model provide a kind of improved have stop the device that returns water, gas ability on the sewer more by force.

The utility model is made of water butt, mozzle, non-return plug and shell.Water butt is fixedly mounted on the top in the shell body, and the top of water butt has the overflow slotted eye.The mozzle upper end is installed on shell or water butt top, and its body stretches in the water butt, and mozzle lower end and water butt bottom keep a determining deviation.In the mozzle lower end non-return plug is set.

Fig. 1,2,3, the 4th, the utility model structural representation.

Accompanying drawing has been described the utility model, and Fig. 1-4 has described several enforcement structure of the present utility model.

Shown in Figure 1, airtight being fixed on the shell 1 of water butt 2 usefulness thread connection.Airtight being fixed on the shell 1 of mozzle 3 usefulness screw threads contact.Water butt 2, airtight being fixed on the shell 1 of the also available screw in compression of mozzle 3.

Mozzle 3 shown in Fig. 2,3,4 is to be fixed on the water butt upper end to be fixed on the shell with water butt 2.

Shown in Figure 4, shell can be made of the system of the giving structure in when building.

Shown in Figure 3, connect sewer pipe connecting tube 9 at spout hole 8 places of water butt 2.This device does not have shell 1 this moment, replaces shell 1 installing and fixing in use by water butt.

The utility model can be installed a screen cloth 10 on mozzle 3, this device is directly installed on the pond.When 1(does not have shell 1 outside yet at water butt 2) top installs a connecting tube 11, this device is installed in the sewer pipe of setting.

Non-return plug 4 is contained in mozzle 3 lower ends, is subjected to the body buoyancy in the water butt 2 at ordinary times, and non-return plug 4 is that cone cooperates with the lower end of mozzle 3.The tapering β angle of water conservancy diversion 3 lower ends equals or is slightly smaller than the tapering α angle of non-return plug 4.

Non-return plug 4 can be entity or hollow.Can adorn the soft cushion 5 that improves sealability on the non-return plug 4 and be used to control, improve the annular that non-return plug is subjected to the buoyancy size and float on 6,7.The overall weight of non-return plug 4 is less than buoyancy.

Structure of the present utility model arranges and forms aquaporin under the ∽ shape, not only in the liquid sewer capable of blocking in the water butt 2 on return gas, and non-return plug 4 is subjected to buoyancy and fluid lifting force, contraryly returns liquid, gas pressure effect, can block reliably in the sewer on return water, gas, the stream string of blocking-up burning things which may cause a fire disaster in sewer. The hanging washing basin of particularly suitable, pond, urinal, floor drain drainage hole use. This apparatus structure compactness is convenient to install and use.

Claims

1, a kind of non-return device for sewer, it is characterized in that constituting by water butt 2, mozzle 3, non-return plug 4 and shell 1, water butt 2 is fixedly mounted on the top of shell 1, the top of water butt has overflow slotted eye 8, mozzle 3 upper ends are fixedly mounted on the shell 1 or the water butt upper end, and mozzle 3 stretches in the water butt 2, keep a determining deviation with water butt 2 bottoms, non-return plug 4 places mozzle 3 lower ends, cooperates with mozzle 3 lower ends.

2, device as claimed in claim 1 is characterized in that non-return plug 4 and mozzle 3 lower ends are that cone cooperates, and the taper angle β of mozzle 3 lower ends equals or be slightly smaller than the conicity angles alpha of non-return plug 4.

3, device as claimed in claim 1 is characterized in that non-return plug 4 is hollow or entity, and soft cushion 5 and annular float 6,7 can be housed on the non-return plug 4.

4, as device as described in the claim 1,2,3, it is characterized in that

--shell can be made of the system of the giving structure in when building;
