Abstract

The invention relates to an urban and rural high-pressure water distributing system capable of preventing back flow. The urban and rural high-pressure water distributing system capable of preventing back flow is used for preventing the back flow of main devices of the water discharging ends of a water-sealed joint, a floor drain device, a toilet stool and the like. According to the urban and rural high-pressure water distributing system capable of preventing back flow, a traditional zero-pressure municipal water discharging system is thoroughly broken through. A deodorization and spilling-resistant floor drain device, a spilling-resistant and smell-spreading-resistant toilet stool and a water-discharging pipe back-flow-resistant device are arranged between a sewage pipeline inlet and a municipal water discharging pipeline, and the purposes of sewage-back-flow resistance, spilling resistance and smell-spreading resistance are achieved. When water is discharged normally, input sewage is high in water level, a back-flow-stopping ball is pressed in a cavity of the device, so that a water discharging opening is opened; when water is not discharged, the back-flow-stopping ball abuts against an upper opening of the device, so that back flow of smelly water and stink is prevented. The whole water discharging pipeline is made of smooth, sealed and pressure-resistant materials, so that when the pipeline is blocked, the back-flow balls of back-flow resistant devices of relevant places abut against the upper openings of the devices through stink and sewage, the pressure of the blocked portion is continuously increased along with water discharging conducted on other high-level devices, and therefore disintegration and dredging of the blocked portion are achieved.

Description

Reverse-filling town and country High Pressure Drain system

The present invention relates to a kind of for check is carried out in municipal drainage system, town and country, to stop the retrograde technical field of sewage and foul smell.Exactly when level and smooth, the sealing the withstand voltage drainage pipe that manufacture and design installation according to the present invention, the backward flowing preventing devices such as the water back bending of all my inventions of entrances employing, floor drain, closet, with large-scale floor drain, replace cesspool cover, when pipeline is unimpeded, drainage system inside is zero pressure; When occurring blocking, the sewage jack-up that each low level inlet device check ball is risen is at upper eck, stop sewage to drive in the wrong direction, and along with each high lift device forms pressurized effect to drainage system sewage effluent, until obstruction disintegration dredging has also avoided easy the emitting of occurring of traditional drainage system to overflow and general taste.

At present, there are three large defects in known existing traditional municipal drainage system:

The one, owing to adopting zero pressure draining, can only continue to increase caliber and ensure displacement, cause that investment is great, the engineering phase is grown, construct, safeguard complicated problem.Pekinese's problem is exactly because underground drainage facility investment is large, there is no again image, all delays or gathers together, and disaster is come finally now, mend the fold after the sheep is lost as early as possible, and the huge time that need expend while remedying in addition and economic cost are really painful.Just as nowadays enjoying sure Tokyo drainage system, also once because of the decision-making of early stage " first rear underground ", be subject to the puzzlement of city waterlogging on the ground.For the solution of this puzzlement, they have spent 30 or 40 years fully.So-called " there is no foresight, must have nearly sorrow ", urban construction is especially true.

The 2nd, because tall and big major diameter drainage pipe is convenient to sewage trickling, due to zero pressure sewage be unhurried current easily make solids of sedimentation in sewage, just as human body easily forms thrombus, just accumulated over a long period line clogging, want dredging, ancients will arrange dredging well with person who happens to be on hand for an errand's dredging of going down in the certain distance of drainage network, cause present many road manhole problems.Well lid is often stolen now rolls damage with vehicle, has become the heavy burden of government, and they think long and hard for a long time, take countless tricks, are still difficult to extricate oneself.

The 3rd, due to pipeline material disunity, have cement, cast iron, rough surface resistance is large, added many quarter bend pipelines, easily forms and stops up.Once stop up, form, sewage just emits excessive from opening parts such as nearest water back bending, floor drain, closets, although nigh well lid place dredging, because hydraulic pressure is little, a little less than obstruction place scouring force, after stopping up again soon, herein with regard to the anthropoid thrombus of class, so people will contact everyday, disclose Gu Li, what small advertisement was maximum is exactly these.Especially for a long time, only Qingdao just has every year and a large amount of because building resident family drainage pipe stops up, causes low layer resident family to be occurred by the event of flooding, upper and lower resident family contradictory, even own poker drainage pipe in addition, make the self-insurance of trying every possible means of also having to of last layer resident family, not only destroy building body, and increased piping cost and finishing burden.Same saloon bar, because basin, floor drain, water closet etc. can not stop sewage to emit excessive, general taste, haves no alternative but use perfume deodorizing, but the non-constant of effect, the taste of mixing makes us endurable.

In the urgent need to a kind of reliable, economic, safe, durable bilge water resisting and foul smell, emit the town and country High Pressure Drain system of overflowing and pouring in down a chimney now.

Goal of the invention of the present invention is to provide a kind of town and country High Pressure Drain pipe-line system and replaces traditional drainage system, take level and smooth, sealing, withstand voltage drainage pipe and the water back bending of entrance, floor drain, the device of closet complete non-return replaces well lid to gather, passage is tall and big, rough surface, there is traditional drainage pipe at dead angle, utilizing system self pressure-raising effect that obstruction is crushed to the mode that disintegration carrys out dredging pipeline replaces traditional, bothersome, effort, expensive, dangerous, dredge blockage manually goes into the well to draw and digs dredging method repeatedly, reach social harmony, environmental friendliness, build, maintenance cost is cheap, municipal drainage management is easy, efficiently, safety, drainage system is reliable, economical, the comprehensive benefit of automatic dredging.

Technical scheme of the present invention is: whole drainage system pipe network is all taked smoothly, sealing, withstand voltage material manufacture, design, installation; The inlet device complete non-return of drainage pipe (all the reverse-filling water back bending of my invention of employing, floor drain, closet etc.); Each drainage pipe caliber, according to 5 of actual displacement times of designs, need not do the great tall and big outlet tunnel of investment; Manhole covers replaces (when occurring stop up and still cannot dredge by pressure-raising, can from then on press check ball and sluice, with dredging machine, add pipeline to get through) with large-scale reverse-filling floor drain; Interior of building all draining terminals (water back bending, floor drain, closet) at all levels all adopt me to realize check by the backward flowing preventing device of invention.

The invention has the beneficial effects as follows: during normal draining, the sewage of each entrance enters pipeline by reverse-filling terminal device in a large number, sewage causes the water level of terminal device inside higher than water seal face, the check ball that sewage is depressed terminal device inside is retracted in water seal cavity, sewage flows into siphon piping, under siphonage, sewage inertia is taken away, and the check ball of terminal device inside is because diameter is greater than the vertical oval cross section in cavity bottom side, be blocked in cavity; When main pipeline occur to stop up or emits, overflow and during general taste, what be subject to due to check ball is the make progress power of jacking of sewage or foul smell, gets lodged in the eck on terminal device cavity top, has therefore stoped sewage and foul smell to drive in the wrong direction; Along with resident family upstairs constantly increases draining, make cavity and Outer Tube internal pressure increasing, can make obstruction place occur the sliding even disintegration of pine; When even pressure is not high, if had backward flowing preventing device by other outfall of blocked pipeline, be also convenient to just can solve line clogging problem with instruments of simply calming the anger such as skin plungers; At ordinary times, due to check ball by water seal supporting at cavity eck, completely cut off retrograde sewage and foul smell; Even if it is many that the water of water back bending water seal has evaporated, check ball also can get lodged in the eck of cavity and seal foul smell emitting be pushed away while overflow occurring, and has avoided conventional terminal device to deposit the drawback that smelly water emits foul smell, has solved well reverse-filling and has emitted excessive problem.

Accompanying drawing is structure principle chart of the present invention, and as Figure of abstract.

1. construction floors in figure, 2. reverse-filling floor drain, 3. check ball, 4. reverse-filling water back bending, 5. reverse-filling closet, the 6. large-scale reverse-filling floor drain in road surface, the 7. drainage pipeline networks of high pressure resistant level and smooth sealing.

As shown in drawings, the present invention consists of the organic connections such as drainage pipeline networks (7) of construction floor surface duct interface (1), reverse-filling floor drain (2), check ball (3), reverse-filling water back bending (4) and reverse-filling closet (5), large-scale reverse-filling floor drain (6) and high pressure resistant level and smooth sealing.

Wherein the drainage pipeline networks (7) of construction floor surface duct interface (1) and high pressure resistant level and smooth sealing forms whole High Pressure Drain system main pipeline; Reverse-filling floor drain (2) is screwed into by the screw socket of floor pipeline interface, can be high pressure resistant and sealing, can screw down cleaning at ordinary times; Reverse-filling water back bending (4) is connected by conventional hoses with the basin on it; Reverse-filling closet (5) inner sealing check ball (3) is connected with the drainage pipeline networks (7) of high pressure resistant level and smooth sealing with closet hydrocone type water back bending pipeline; As for ground sewage, to enter the drainage pipeline networks (7) of high pressure resistant level and smooth sealing, will large-scale reverse-filling floor drain (6) be installed according to land drainage layout and spacing, the reverse-filling floor drain amplifying.

Detailed process is as follows:

Normally not during hull-borne, check ball (3) floats on the eck of water seal under water seal buoyancy in each terminal device internal cavity, retrograde rancid rotten sewage and air-flow are blocked in cavity, may be owing to not having for a long time sewage to come in to supplement to cause part water seal evaporation, check ball (3) may fall, once emit excessive, check ball (3) can be shifted onto on the upside down funnel shape port on eck and cavity top equally, can solve well the excessive problem of emitting of smelly water and foul smell; During draining, the pressure that the sewage short time enters the upside down funnel shape port that makes terminal device eck and cavity top is in a large number greater than the buoyancy of water seal to the check ball (3) in cavity, the check ball (3) in cavity is pressed in cavity water seal, large amount of sewage enters in the drainage pipeline networks (7) of high pressure resistant level and smooth sealing by the vertical oval guide hole in cavity bottom side, and under siphonage, sewage inertia is taken away, and check ball (3) in terminal device cavity is because diameter is greater than vertical oval guide hole cross section, cavity bottom side, is blocked in cavity and is not sucked away; When the drainage pipeline networks (7) of high pressure resistant level and smooth sealing occurs to stop up or emits excessive and general taste, what be subject to due to the check ball (3) in terminal device cavity is the make progress power of jacking of sewage or foul smell in cavity, can get lodged on the upside down funnel shape port on eck and cavity top, therefore stop sewage and foul smell to drive in the wrong direction; Along with building, each floor resident family constantly increases draining, make the upside down funnel shape port on eck and cavity top and the drainage pipeline networks (7) of check ball (3) and high pressure resistant level and smooth sealing jointly bear pressure increasing, can make obstruction place occur the sliding even disintegration of pine; When even pressure is not high, if had backward flowing preventing device by other outfall of blocked pipeline, be also convenient to just can solve line clogging problem with instruments of simply calming the anger such as skin plungers; Once pipeline is unimpeded, check ball (3) etc. returns to normality.
