Description

The water seal floating head is dual every smelly, insect protected dewatering installation

Technical field

The present invention relates to the building water supply and drainage field.

Background technology

The water seal floating head is dual every smelly; the insect protected dewatering installation is to application on July 22nd, 2003 and is awarded Patent right vertical type every smelly; the technological improvement of fungi-proofing water trap; in practice; vertical type is every smelly; water seal layer in the fungi-proofing water trap structure; the same with other water seal foul preventers; the capital is subjected to the influence of positive and negative air-flow air pressure in the sewer; suffer air-dry and destruction; and at northern area; especially the dry and room heater effect of winter climate; the water yield of water seal layer is easy to be evaporated minimizing; how to protect the water seal layer, how be evaporated and reduce or when withered, make the water trap still can be every the problem of smelly insect protected in the water seal water yield; technology lacks good solution; for solving this type of problem, what have takes to abandon water seal, uses instead merely with the unlatching every smelly capping of mechanical spring or magnetite principle control gutter; the foul preventer of closing; but this type of mode still exists line up every smelly bad sealing; mechanical aging, corrosion, malfunctioning problem.And according to an expert view, water seal is at present every smelly effect best techniques.

Summary of the invention

The water seal floating head is dual to be exactly the invention that designs at addressing the above problem every smelly insect protected dewatering installation, it is adopting on the best water seal technical foundation of smelly effect, adopting again increases a floating head every smelly layer on the water seal layer, be that the water seal remedies the deficiency of mechanical capping every smelly sealing structure imprecision etc., available again capping stops the destruction of the positive and negative air-pressure that water seal is produced by the sewer air-flow and remedies the water seal water yield every smelly structure and reduce the deficiency that exists, and can play dual every smelly insect protected effect more reliably.

Adopt water seal and floating head dual, make every smelly vermins-proof effect and obtain double insurance every smelly, insect protected sealing combination.Water seal can remedy mechanical capping poorly sealed close problem may occur, after the floating head envelope can play and remedy the evaporation of the water seal water yield, when the water yield reduces, every problem smelly, that vermins-proof effect reduces.And the floating head cap seal principle that adopts, be to utilize the waterpower of draining and buoyancy to open the floating head draining, with the gravity sinking effect realization sealing process of floating head self.

Because the direction that design is closed floating head, it is negative pressure direction along sewer, the i.e. pressure directions that produces of the air-flow that flows to pipeline opening, so, the air-flow that outwards blows in sewer is big more, and the negative pressure of generation is big more, and promptly the pressure that floating head is closed is big more, it is tight more that floating head is closed, every smelly, vermins-proof effect is good more.This principle also just in time is applicable to when sewer stops up, the sewage overflow in the blocking-up sewer.When sewer stopped up, the make progress direction of drainage pipe of effluent stream just had been same as the direction of negative pressure in the sewer, when the sewage overflow is to floating head, promptly can produce hydraulic pressure to floating head, made tighter that floating head closes, thus the passage of blocking-up sewage overflow.And the principle of dynamics of floating head is to utilize the waterpower of draining and buoyancy to open, realize closing function with the gravity sinking effect of floating head self, this makes the opening and closing power of floating head, as long as have the waterpower of draining stream and buoyancy to exist, exist with the gravitation of the earth, just aging malfunctioning never.In addition, the manufacturing materials of floating head is to adopt plastic material, does not also have the corrosion problem.

Global feature of the present invention is, draining characteristics according to wash basin and pond, the water seal floating head is dual every smelly, a small-sized sealing tank body is made in the insect protected draining, the tank body lower edge can be covered and be fastened underground water channel mouth of pipe face sewer mouth of pipe peripheral space hermetically, the last gutter of one connection wash basin or pond sewer pipe is arranged at small-sized sealing tank body top, last gutter enters in the sealed shell of tank through the tank body seal cover, reaching a supported unsettled bowl-shape accumulator claims in the interior bowl, make the gutter lower outlet be lower than interior bowl the rim of a bowl plane certain depth, a bowl water water surface is higher than gutter lower outlet plane in utilizing, formation to the last gutter mouth of pipe every smelly insect protected water seal layer.On interior wrist the rim of a bowl, one airtight in the floating head of bowl the rim of a bowl, when last not draining of gutter, the interior bowl water water surface is together in interior bowl the rim of a bowl plane, floating head under action of gravity, bowl the rim of a bowl in covering and sealing, form to the last gutter mouth of pipe every smelly, insect protected capping layer.When last gutter down during draining, the draining current enter interior bowl from last gutter, upwards revolution, its waterpower and buoyancy upwards raise the floating head on interior bowl the rim of a bowl, open interior bowl the rim of a bowl, make the draining current flow out interior bowl, flow to unsettled interior bowl, the following gutter of face sewer mouth joinably in the sealed shell of tank of below is through gutter inflow surface sewer mouth down.When last gutter draining finishes, in interior bowl water water level drops to during bowl bowl plane, the floating head on interior bowl the rim of a bowl under action of gravity, fall after rise again covering and sealing in bowl the rim of a bowl, recover the cap seal layer.Cap seal is not dual every smelly, insect protected structure to make water trap return to the tired guest's water seal of gutter.

Description of drawings

Accompanying drawing is an inner space of the present invention shape sectional view.

In the drawings: bowls in gutter on 1,2 tank body seal covers, 3 floating heads, 4,5 sealed shell of tank, 6 times gutters, 7 ground sewer mouths.

The specific embodiment

Whole water seal floating head is dual every embodiment smelly, the water-proof drainage device, gutter 1 enters in the tank body through tank body seal cover 2 on small-sized sealing tank body 5 tops, stretch in the interior bowl 4 of a supported unsettled bowl-shape accumulator, make the lower outlet of gutter be lower than interior bowl the rim of a bowl plane certain depth.Bowl water water level is higher than gutter lower outlet plane in utilizing, formation to the last gutter mouth of pipe every smelly, insect protected water seal layer is on interior bowl the rim of a bowl, one can be airtight in the floating head 3 of bowl the rim of a bowl, when last gutter 1 not draining, the interior bowl 4 water waters surface are together in the rim of a bowl plane, floating head 3 is under action of gravity, bowl 4 the rims of a bowl in covering and sealing, formation to last gutter 1 mouth of pipe every smelly, the insect protected capping layer, floating head 3 can be raised unlatching under the waterpower of draining current and buoyancy, when the waterpower of draining and buoyancy, floating head 3 can rely on self gravitation to fall back to interior bowl 4 the rim of a bowl upper covers and live interior bowl 4 the rims of a bowl, above structure can be made with plastic material, and manufacture craft is simple, and is with low cost, use the dual water trap of water seal floating head every smelly insect protected, need not existing building and finishing are carried out big change, no matter new and old buildings all is suitable for, as long as guarantee that the ground of underground water channel mouth of pipe periphery is smooth.And easy for installation, the ordinary people can bring promptly and use.As long as gutter under the dual deodorization of water seal floating head, the insect protected water trap is stretched in the sewer mouth of ground, make sealed shell of tank lower edge cover fasten underground water channel mouth of pipe surrounding ground, make its sealing, the last gutter mouth of pipe that again gutter in wash basin or pond is inserted this water trap can obtain dual every smelly, vermins-proof effect.Where necessary, available thimerosal pours into from last gutter, make its flow in bowl, and fill, can stop virus in the sewer and bacterium to external diffusion together with inner floating head, accomplish floating head sealing and disinfection and isolation.
