Description
The invention belongs to sanitary installation blowdown, deodorization, anti-reversing clutch.
The drainage of sanitary installation, in order to prevent the foul smell diffusion, generally all water is isolated the sealing method, realizes that this method mostly is multi-form stench trap.This method and corresponding structure thereof are though energy blowdown resistance is big, easily obstruction; Can deodorization but externally pressure more than or equal under the prerequisite of internal pressure effectively.With water is that barrier does not have one-way, can flow through by dirt, also can flexible contaminants counterflow.Especially when trunk line stops up, sewage, dirt often take place against overflowing, living environment has been caused severe contamination.
Specific tasks of the present invention are: a kind of automatic deodorising and anti-reverse device for sewer is provided, and blowdown and closed process are finished automatically.It can not only prevent foul smell diffusion, again can bilge water resisting, dirt is contrary overflows.Its deodorization, anti-reverse function are not subjected to inside and outside pressure variable effect.Thereby can stop down the pollution of water to living environment.
The present invention is that following method realizes: automatic deodorising and anti-reverse device for sewer comprises housing and the water seal of being made up of loam cake, following cover, water seal is made up of loam cake, sealing ring and sewage door, sewage door is with after the ring that resets is connected by stay cord, by fixed pulley composition pulley motion mechanism.Resetting the weight of encircling should be greater than the weight of sewage door, and sewage door and sealing ring are in closed state at ordinary times, and the ring that resets has more the weight of sewage door, should make the water that has height more than 10 millimeters above the sewage door, the balance of how many energy governor motions of water.The form of structure of loam cake can enlarge range of application like this according to the using and cooperate requirement to determine of various sanitary installation.Below the various loam cakes, all split three fixed pulley framves by 120 °.The shape of sewage door is ganoid taper shape, and the surface is difficult for depositing retentate, and sewage door is the hollow shell body that following periphery has muscle, has certain intensity and weight reduction.According to the different size requirement, can also below shell, establish some muscle lattice when diameter is big, to gain in strength.On the muscle of periphery, set up three holes separately by 120 °, be convenient to be connected with stay cord.The ring that resets is a metal ring, and section is right-angled trapezium preferably, because of the inclined-plane is difficult for depositing retentate, should set up three holes separately by 120 ° on the plane of ring, is used to connect stay cord.Stay cord is answered soft, the high distortion that is difficult for being stretched of intensity, acid-alkali-corrosive-resisting.When the length of rope was in uppermost position in fig-ure when the ring that resets, the sewage door periphery was in the cavity centre position, and blowdown this moment handling capacity is preferable.Sealing ring is in section is convex tendon to be arranged, and lower edge, the outside is the dovetail shaped annulus.Convex tendon is enclosed within the cannelure of loam cake lower end, and is easy for installation.The lower edge dovetail shaped can increase elasticity, improves sealing effect.Loam cake inlet, following cover outlet can be determined bore and bind mode according to the concrete situation of sanitary installation.
The present invention has used fixed pulley balance of mechanism principle, has designed the fixed pulley motion of being made up of the ring that resets, fixed pulley, sewage door.Reset the ring weight greater than sewage door weight, at this moment sewage door and sealing ring deadend at ordinary times also have water high more than 10 millimeters above the sewage door.During stable level, mechanism is in balance, and formed mechanical envelope and add water seal this moment.Because mechanism is in balance, small external force can make mechanism action, so open highly sensitively, dirt is by own wt eliminatings of just opening the door, external force disappearance after the dirt, and sewage door is closed automatically.When last surface pressure reduced or surface pressure increases down, sewage door was upwards closed tighter.Therefore possessed unidirectional automatic pollution discharge, deodorization, anti-reverse function.Visual from the mechanics angle is the opening pass-through state at ordinary times, and the blowdown resistance is little, difficult to be stopped up.This anti-reverse device has adopted the cramped construction of circular symmetry, and is easy for installation.This anti-reverse device can use separately, as all size floor drain usefulness, also can with multiple sanitary installation, as urinal, bathtub, chemical examination basin ... etc. supporting use.
Accompanying drawing 1 is an exemplary embodiments of the present utility model: the overall structure longitudinal sectional drawing of floor drain.
Accompanying drawing 2 is a kind of general loam cake longitudinal sectional drawings of the present utility model.
Accompanying drawing 3 is sewage door schematic diagrames.
Accompanying drawing 4 is sealing ring schematic diagrames.
Realize this automatic deodorising and anti-reverse device for sewer best way, accompanying drawings is as follows: as exemplary embodiments, accompanying drawing 1 is a floor drain.Known floor drain is because design feature, and the water ditch is narrow, easily stop up and water few, the very easy evaporation of water is done, thereby floor drain often is in anhydrous state, only water seal resistance disappears, foul smell diffuses out in a large number, is one of the most serious pollution sources.
Accompanying drawing 1 specifically comprises loam cake (1) and covers housing and the water seal (5) that (4) are formed by the seam cooperation down, water seal is made up of loam cake (1), sealing ring (6) and sewage door (7), sewage door (7) is with after the ring (8) that resets is connected by stay cord (9), hang over the both sides of fixed pulley (3), form the fixed pulley motion.Fixed pulley (3) is installed on the following fixed support (2) of loam cake (1).The weight of ring is greater than the weight of sewage door owing to reset, and sewage door and sealing ring sealing have height and be the water (5) more than 10 millimeters above, and at this moment mechanism is in equilibrium state.How many energy of water are the balance of governor motion automatically.During balance of mechanism, as long as very little external force, sewage door just can sensitive upper and lower motion.Open downwards blowdown, upwards increase sealing ability.Be expedite opening pass-through state during from the visual balance of mechanics angle, dirt only depends on deadweight just can get rid of smoothly.As shown in Figure 3, sewage door (7) be shaped as ganoid taper shape, periphery has the following empty thin walled shell of muscle.The sewage door that specification is big can also be set up some muscle lattice at the shell inner surface, to improve intensity.Set up three holes separately by 120 ° on the sewage door periphery muscle, to connect stay cord (9).As shown in Figure 4, being shaped as of sealing ring (6) has convex tendon in the section, and lower edge, the outside is swallow-tailed annulus.Sealing ring is answered high resilience, and energy weak acid resistant alkali, oil resistant and anti-aging improve the life-span.When anhydrous, should guarantee 1.5～2.0 millimeters compression height.The ring (8) that resets is a metal ring, and section is right-angled trapezium preferably, and the inclined-plane is difficult for depositing retentate.Reset the ring the plane on set up three holes separately by 120 °, be used for being connected with stay cord (9).The length of stay cord (9) is that the periphery of sewage door is in the cavity centre position when the ring that resets is in uppermost position in fig-ure, and blowdown this moment handling capacity is preferable.Stay cord should soft, the high distortion, corrosion-resistant that is difficult for being stretched of intensity.Accompanying drawing 2 is a kind of general loam cakes, can connect with multiple sanitary installation to use.Produce and preferably adopt plastics and plastics forming technique, also available certainly other materials and process implementing.
