Description
Technical field
The utility model relates to a kind of gas-water separation swirler.
Background technology
At present indoor drainage great majority building all adopts traditional interior plumbing system: promptly by Double tube (or the three control) drainage system of gutter and specific vent stack (specific vent stack only is meant and is connected with drain header, the vertical aeration road that is provided with for the drain header inner air flow) composition.
Though the history that traditional indoor drainage technology is used existing decades in China, but some difficult problems still do not solve, as noise problem, waste water overflow problem, drip and leakage problems etc., and along with development of times, some new problems show especially out again, put restricted etc. as sanitary apparatus.Therefore the improvement of traditional interior plumbing system and optimization more and more demonstrate urgency and importance, and it is very necessary strengthening the improvement of interior plumbing system and optimizing research.
From the sixties. the single-stack drain system of cancellation vent stack has just been arranged.In high residential building of today, the way that adopts stack vent more and amplify the discharge pipe caliber.Then adopt stack vent in external this type of common highrise building, be equipped with Soviet Union's Vito special pipe fittings such as (gassy water blender and moisture traps), make gas-water separation, strengthen the soil stack water passing capacity.Gas-water mixer function wherein: restriction sewage and air are at the flow velocity of standpipe; Prevent that standpipe is by sewage what plug and build-up of pressure fluctuation; The sewage that flows to from transverse tube can be mixed effectively with air and the sewage that has flowed in standpipe.Moisture trap function: the volume of gas being separated thereby reduced sewage from the air-water mixture that flows down along standpipe; Reduce flow velocity and guaranteed that sewage flows into total horizontal main reposefully, reached the counter-pressure composition that prevents that the riser bottom generation is excessive.
The rigid polyvinyl chloride UPVC helix tube that drops into Chinese market at present generally is used as the standpipe of indoor sewage or rainwater.Studies show that rigid polyvinyl chloride UPVC helix tube can reduce by 5～7 decibels of noises than common rigid polyvinyl chloride UPVC pipe, noise power is the latter's 1/ 3～1/ 5.But because its output capacity is low, costing an arm and a leg, is 3～4 times of common polyvinylchloride tubing price, makes to apply to be restricted.
The utility model content
The purpose of this utility model is that noise is big in the interior plumbing system, floor space is big in order to solve in the market, the inner easy pressure oscillation of pipeline, damage of water block and the expensive problem of existing special pipe fitting, has proposed a kind of gas-water separation swirler that is used for interior plumbing system.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described cyclone is by first pipeline, second pipeline, two first flow deflectors and one group of second flow deflector constitute, each first flow deflector is a crescent shape, two first flow deflectors are along the inwall upper and lower settings of first pipeline, the concave surface of two first flow deflectors is oppositely arranged, the inwall of the convex surface of each first flow deflector and first pipeline matches, and the two is affixed, the plane at each first flow deflector place and the angle β between the vertical line are 35 °～45 °, described second pipeline inner wall is uniformly distributed along the circumference and is provided with one group of second flow deflector, each second flow deflector is a triangle, one side of each flow deflector is affixed with the inwall of second pipeline, the angle α of the plane at each second flow deflector place and the second pipeline central axis is 50 °～70 °, and an end of described first pipeline is connected with an end of second pipeline and makes one.
The utlity model has following beneficial effect: 1. solved the noise problem in traditional drainage system: easily produce the current noise in the gutter standpipe, particularly in the kitchen or the washroom, as long as draining upstairs, tangible sensation is just arranged downstairs, the adherent rotation of sewage flows downward in the standpipe and the utility model can make, gas-liquid two-phase separately reduces the gas concussion, thereby abates the noise; 2. save tubing, reduce indoor floor space: often adopt two standpipes even three stack drain systems in traditional high layer sewerage system, and the drainage system that moisture trap is installed adopts single-stack drain system and cancelled ventilating pipe in the past, a large amount of tubing have been saved, reduced the floor space of ventilating pipe simultaneously, made and to utilize the space to increase at building interior; 3. prevented pressure oscillation effectively, prevented damage of water block: because effluent stream eddy flow behind moisture trap falls, the middle airway that forms increases the air inlet area, effectively control valve internal pressure fluctuation, prevent the water seal exhaustion, draining is smooth and easy, not stifled, gastight purpose thereby reached; 4 have very high economic worth: present drainage ventilation effect helix tube has preferably limited its application owing to cost an arm and a leg.And the utility model is made by common polyvinylchloride tubing, just can reach the result of use of helix tube.
