Description

One kind preventing sewage outflow device

Technical field

It is sanitary ware and the kitchen of a kind of toilet the present invention relates to the device in foul water system in building field Between sink foul water system in one kind prevent sewage outflow device.

Background technique

With constantly improving for science and technology, national economy quickly increases significantly to be mentioned with living standards of the people Height, the emergence of real estate and the development of home decoration industry, so that home decoration products and living utensil are developed rapidly, So that its product variety is more and more, style is increasingly newer, structure is more and more reasonable, performance is become better and better.But as household There is also unsatisfactory ask in this way and like that for the blow-off line of ornament materials, engineered building materials and home life facility Topic, the especially general pipeline of skyscraper drainage are often easy blocking, and the sewage effluent of all owners of blocking of general pipeline will The drainage spilling for focusing on bottom owner's family is really impossible to guard against.

There are no one kind really can effectively prevent sewage outflow device, the total blockage of blowdown for existing foul water system Sewage will be concentrated to be overflowed from the exhaust system of bottom owner's family；This problem perplex always bottom owner normal life he Can effectively prevent sewage outflow device there is an urgent need to one kind, ensure bottom owner quiet normal life safely.

Summary of the invention

To solve the above-mentioned problems, sewage outflow device can be effectively prevent to the present invention by providing one kind for market, the device It is that one kind prevents sewage outflow device.

One kind preventing sewage outflow device, is made of valve seat, valve head, bleeder and the big component of discharger four, It is characterized in that valve body and spool.

Above-mentioned valve body is formed by valve seat and valve are first, and valve seat covers the either valve head plug sleeve on valve head and uses on valve seat Ultrasonic wave is either bonded together with glue；Valve seat is common sewage pipe, and design in this way substantially reduces development cost, is reduced Manufacture difficulty guarantees product quality；Above-mentioned spool is the several piston synthesis of a piston or the jacketed pipe structure of piston At casing is common plastic tube, and design in this way reduces manufacture difficulty, guarantees to produce also for development cost is substantially reduced Quality；Upper piston area has the slot of a placement sealing ring, and the sealing ring of spool is stuck in the first tapered internal diameter of valve by buoyancy Upper prevention sewage outflow；There are several guiding ribs on piston external diameter, can precisely block sewage inlet when floating upwards and effectively hinder Only sewage outflow.

Above-mentioned bleeder is the scupper hose being connected on valve body by nut, or is inserted directly into valve body internal drainage Ordinary draining pipe on hose, or link valve body.

Above-mentioned discharger is threeway or the drainpipe of the elbow drainpipe of valve body insertion drainpipe Trap, they are bonded together using glue.

Spool is in the bottom of valve body when sewage discharge, and sewage inlet is that normally opened sewage can smoothly enter valve body It is discharged by tapping equipment；When the sewage of the total blockage high level of blowdown is merely able to flow back into valve body from minimum one layer of drainage It is interior so that be full of sewage in valve body, spool will generate to buoyancy sealing ring block sewage inlet above prevent sewage from Sink is excessive.

Detailed description of the invention

With reference to the accompanying drawing and example, the present invention is further described.

Fig. 1 is a kind of structural schematic diagram for preventing sewage outflow device fastening-type hose.

Fig. 2 is a kind of structural schematic diagram for preventing sewage outflow device plug-in type hose.

Specific embodiment

In figure, spool (1), casing (1-1), piston (1-2), sealing ring (1-3), guiding rib (1-2-1), slot (1-2-2), Valve body (2), valve head (2-1), valve seat (2-2), screw thread (2-1-1), sewage inlet (2-1-2), bleeder (3), seal washer (3-1), nut (3-2), hose (3-3), discharger (4), sewage pipe (4-1), threeway (4-2), lid (4-3), trap (4-4)。

Fig. 1 is a kind of structural schematic diagram for preventing sewage outflow device fastening-type hose；Be by spool (1), valve body (2), Bleeder (3) and the big component of discharger (4) four are formed, it is characterised in that valve body and spool.

Above-mentioned valve body is made of valve seat (2-2) and valve first (2-1), and valve seat is common sewage pipe, and valve head is covered in valve seat On, it is bonded together with ultrasonic wave either glue, the sewage inlet (2-1-2) of valve head is tapered aperture.

Above-mentioned spool is the piston that its underpart piston (1-2) is cased with plastic bushing (1-1), and upper piston area is to be cased with sealing ring The slot (1-2-2) of (1-3) has several guiding ribs (1-2-1) on the outer diameter of piston；Floating can accurately block valve upwards for it First sewage inlet prevents sewage outflow.

Above-mentioned bleeder is a kind of fastening-type hose (3-3)；It includes hose, fastening nut (3-2) and seal washer (3-1) is constituted；It is by screw thread (2-1-1) lock sealing on fastening nut and seal washer and valve head.

Above-mentioned discharger is the upper port of body base insertion Y-junction of drainpipe (4-2), and lower port is with lid (4- 3) it blocks, central port is sewage pipe (4-1) connection blowdown general pipeline, they are sealed with gluing knot.

Fig. 2 is a kind of structural schematic diagram for preventing sewage outflow device plug-in type hose；Its by spool (1), valve body (2), Bleeder (3) and the big component of discharger (4) four are formed, it is characterised in that valve body and spool.

Above-mentioned valve body is made of valve seat (2-2) and valve first (2-1), and valve seat is common sewage pipe, places valve in valve seat Head is bonded together with ultrasonic wave either glue, and the sewage inlet (2-1-2) of valve head is tapered inner hole.

If above-mentioned spool is made of stem piston, attached drawing is two pistons, and upper piston area is cased with sealing ring (1-3) Slot (1-2-2) has several guiding ribs (1-2-1) on the outer diameter of piston；Floating can accurately block sewage inlet upwards for it Prevent sewage outflow.
