Description
Technical field
The invention belongs to the construction drainage technical field, be specifically related to a kind of eddy flow drain connection of single-stack drain system waste pipe connection usefulness in the building.
Background technique
The building drainage system is the drainage system of middle-high building thing particularly, and former use most is double profile tube drainaging system, and a standpipe is exclusively used in draining, and another root standpipe is exclusively used in ventilation.This drainage system floor space is big, and it is many to consume tubing.
Also have and use common single-stack drain system, but common single-stack drain system is because at water downwards in the row, the gas in the pipe is upwards row; Influence the hydraulic regime of draining, in pipe water more for a long time, gas is arranged and not to be gone out; Cause problems such as the interior obstruction of pipe, its draining operating mode is bad.
In single-stack drain system, adopt special single standpipe at present, special single-stack drain system has only a standpipe more, and this standpipe is the water vent ventilation; It is few that therefore special single-stack drain system consumes tubing; It is little to take up room, easy construction, and its market share is higher.
Special single standpipe is mainly that than the special way of common single standpipe it lets the water of discharging in standpipe, produce the eddy flow wall attachment effect; The water of rotation is close to tube wall; Thereby in the middle of standpipe, form air-core; Gas passes through from air-core, thereby has realized in a standpipe both functions of water vent ventilation, has played the effect of double profile tube drainaging system.
The main cause that above-mentioned driving draining produces eddy flow is the pipe joint that can guide the water generates eddy flow that adopted on single standpipe; A kind of rotary flow type pipe joint is disclosed in the license notification number is the Chinese utility model patent specification of CN201539658U; It comprises union body; Vertical tube upper and lower end at union body is respectively equipped with water intake and drain opening; The side of pipe joint is provided with at least one side water intake, and the diameter of cavities is greater than the diameter of last water intake, drain opening and side water intake in the vertical tube of union body, and cavities connects along tangent line in the intake tunnel of side water intake and the vertical tube of union body; The vertical tube inwall of union body is protruding with spiral water conservancy diversion rib; The tube wall of water conservancy diversion rib and union body is fixedly connected into integral body, and the water conservancy diversion rib is between last water intake and drain opening, and the water conservancy diversion rib descends along the water inlet direction spiral of side water intake; The water conservancy diversion rib is divided into water conservancy diversion rib and following water conservancy diversion rib; The spiral conducting line of the spiral conducting line of last water conservancy diversion rib and following water conservancy diversion rib is identical or different, and both are provided with epimere water conservancy diversion rib along the annulus that the vertical projection overlapping formation of the vertical bearing of trend of union body is accomplished or do not accomplished in the upper end of last water conservancy diversion rib; Epimere water conservancy diversion rib is between last water intake and side water intake, and the spiral conducting line of epimere water conservancy diversion rib is identical or different to the spiral conducting line of water conservancy diversion rib with down.The water flowing at vertical tube middle part that gets into union body by last water intake and side water intake in the disclosed pipe joint of above-mentioned specification is after dilatation, slowing down flow velocity; Descend by epimere water conservancy diversion rib, last water conservancy diversion rib and following water conservancy diversion rib guiding water flowing vertical tube tube wall spiral along pipe joint; Make the center portion of pipe joint form the air-core of being convenient to ventilate; Being beneficial to the discharge of gas, is the function that draining is ventilated again thereby be implemented on single standpipe.
Because cavities connects along tangent line in the intake tunnel of side water intake and the vertical tube of union body; It is tangent to get into the Hand of spiral of approach axis and the water flowing the union body of water flowing of union body from the side water intake like this; Can not produce when the water flowing of side water intake gets in the union body and impact with the spiral water flow that produces through the guiding of epimere water conservancy diversion rib in the union body; Thereby the reduction draining noise guarantees the intraductal atmospheric pressure balance.But the union body that uses often adopts foundry goods or plastic at present; Pipe joint as threeway or four-way is integrally formed with the side intake pipe on the vertical tube of union body; The joint that is connected with vertical tube on the side intake pipe is provided with the water outlet that is communicated with the middle cavities of vertical tube, and the tube cavity of side intake pipe is the intake tunnel that the middle cavities tangent line with vertical tube connects.The joint that is connected with vertical tube on the side intake pipe is connected with the vertical tube tangent line; Water flowing just tangentially gets in the vertical tube in the side intake pipe like this; Converge mutually with the rotary water current that flows through in the vertical tube; But if guarantee as far as possible all to flow in the vertical tube along tangent line from the water flowing that the water outlet of joint flows out, the width that goes out of the water outlet of joint just must reduce so, the equal in length of the cross section of the water inlet of length and the side intake pipe of the cross section at water outlet place of joint that shows as side intake pipe and vertical tube usually on axial along vertical tube on axial along vertical tube; And the width at water outlet place is less than the width of water inlet, thereby forms a narrower water outlet.And if water outlet is bigger; Water flowing in the side intake pipe no longer flows in the vertical tube along the tangent direction of vertical tube, and this can cause water flowing in the side intake pipe to eddy flow water impact transversely in the vertical tube, produces bigger draining noise; But narrow water outlet can hinder the normal water flowing of side intake pipe to the vertical tube of union body again; Reduce the water flowing flow velocity of side intake pipe, increased the pressure that tube wall bore of side intake pipe, influenced the use of pipe joint.
And the cross section of the water conservancy diversion rib that in above-mentioned utility model patent, is provided with on the inwall of the vertical tube of disclosed pipe joint is a triangle; At this moment, the last helical flank of water conservancy diversion rib and inner tubal wall face out of plumb are like this when the water conservancy diversion rib is flow through in water flowing; Water flowing is except spiral descends under the spiral guiding of water conservancy diversion rib; Also there is part water to have reduced cyclonic action, will influences the formation of single standpipe hollow gaseous core when serious along last helical flank to the caliber central flows.
