Abstract
The invention belongs to the technical field of the auxiliary device of a sewage line, which particularly relates to an anti-backflow device for a sewage line. The anti-backflow device for the sewage line mainly aims at the phenomena of peculiar smell return and dirt overflow of the traditional sewage line. In order to solve the above problems, the invention adopts the technical scheme that the anti-backflow device for the sewage line comprises a shell, a connector, a seal and an end cap, wherein the connector is installed on the left end of the shell; the seal is installed on the right end of the shell; the end cap is installed on the inner wall of the shell; a plush copper of the end cap faces to the right side of the shell; a sliding rod of the end cap is sheathed with a longitudinal bearing and a return spring; the longitudinal bearing is provided with a flow guidance hole; the return spring is positioned on the right side of the longitudinal bearing; and a sleeve is sheathed at the outside of the plush copper of the shell. The anti-backflow device for the sewage line, which is disclosed by the invention, has the advantages of simple structure and convenience in use.
Description
Technical field
The invention belongs to sewer servicing unit technical field, be specifically related to a kind of sewer pipe anti-backflow device.
Background technology
At esidential building with the public place sewer often occurs returning peculiar smell and dirt returns excessive phenomenon, had a strong impact on people's normal life, although the device of some anti counter-flowings is also arranged now, various problems always appear, can not satisfy people's needs.
Summary of the invention
The present invention occurs returning peculiar smell mainly for existing sewer and dirt returns excessive phenomenon, and a kind of sewer pipe anti-backflow device simple in structure, easy to use is provided.
The present invention addresses the above problem the technical scheme of taking to be:
A kind of sewer pipe anti-backflow device, comprise shell, be installed in the shell left end connector, be installed in the sealing of shell right-hand member, wherein: it also comprises the plug that is installed in outer casing inner wall, the plush copper of described plug is towards the right side of shell, sliding bar at plug is set with vertical bearing and back-moving spring, offer pod apertures on described vertical bearing, described back-moving spring is positioned at the right side of vertical bearing, is set with sleeve outside the plush copper of shell.
Rubber sheet gasket of each side installation at described plug.
The present invention adopts technique scheme, and plug integrates sliding bar and plush copper, contacts the reverse circulated that can effectively block lower water with the sealing of rubber spill; Back-moving spring on the sliding bar of plug, in plush copper with vertically between the bearing, can guarantee the washes by water automatic-sealed that rear plug and rubber spill seal that flows away; Vertically bearing is stuck in outer casing inner wall, and is socketed on the sliding bar of plug, for the vertical flexible motion of plug provides support, and the pod apertures around simultaneously vertical bearing or the only way which must be passed of flushing filth-discharging; Sleeve is stuck between outer casing inner wall and the plug in its place ahead with vertically bearing is directly same, and can be plush copper fixed space is provided, also be simultaneously the necessity of assembling and fixing internal part.During flushing filth-discharging, waste water can be washed the plug that gets lodged in the rubber sealing open, pod apertures on vertical bearing, flow into sewer unblockedly, after waste water is emptying, plug is under the effect of back-moving spring, and its plush copper can be sealed automatic-sealed with rubber, thereby reaches the intrusion that prevents peculiar smell and dirt and return excessive.
