Description of drawings
By description of drawings preferred implementing form of the present invention, these forms of implementation only are used for explanation, and should not think restrictive sense below.In the accompanying drawings:
Fig. 1 is according to the sectional view of the pipe branches of first form of implementation of the present invention,
Fig. 2 is according to the sectional view of the pipe branches of Fig. 1, have according to the current divider of second form of implementation and bypass pipe and
Fig. 3 has current divider and bypass pipe according to the 3rd form of implementation according to the sectional view of the pipe branches of Fig. 1.
The specific embodiment
Fig. 1 illustrates a pipe branches 1 in the sewage leader that is used in the tier building.Pipe branches 1 is used for the sewage input pipe of a floor is connected to leader, and leader is extended on whole depth of building to floor by floor mostly.Correspondingly, input pipe is connected with leader via pipe branches 1.
Leader so is provided with, so that its central axis V is on the vertical line.Therefore sewage V vertically flow along falling direction F and wall 20 at leader on or leader section 2,3 in one of formation around cylindrical moisture film or water jacket W.What should mention in this respect is that the sewage of being made up of water and solids is not basically having essential distinction with water aspect the flow effect.
There is an air column L in central area at leader, extends in the leader of this air column between two pipe branches 1.Because the flow motion of water jacket W, air column L is in the pulse feature motion, and one of them excessive pulse has a kind of negative effect to the efficient of pipe branches 1.
The diameter of leader is so definite, so that water flows away as water jacket W when maximum volume flow, wherein also has air column L.If volume flow is so big, so that all to be that it is drained used in the whole cross section of leader, and risk that refluxes via input pipe 7 so and/or the risk that flows backwards via pipe branches 1 are very big.
Sewage by the top leader via inlet 3 along the falling direction F ingress pipe branches 1 that conforms to basically with vertical line V.This effluent stream through top leader section 2 and through turning to section 4 to turn to according to following explanation.In the zone that turns to section 4, extra sewage is introduced leader via input pipe section 7.In case through turning to section 4, the sewage that turns to mixes with extra sewage and via bottom leader section 5 or export 6 and leave pipe branches 1 entering bottom leader.Because flow behavior, in case water also produces a water jacket W and an air column L through certain distance in the leader of bottom then.
Turn to section 4 to be used to slow down the flow velocity of water in input pipe 7 zones, also be used for forming, thereby stop input pipe 7 and the and then emptying of its trap in input pipe 7 restriction negative pressure.Turn to section 4 to comprise first turn-around zone 8 that sewage W is turned to from falling direction F here.One second turn-around zone 9 also is set in addition, and it with respect to falling direction F or with respect to vertical line V with an angle or tilt.Sewage so turns to through first turn-around zone 8, so that sewage redirect on second turn-around zone 9, experiences turning to once more at this sewage.Preferably, second turn-around zone 9 is after first turn-around zone 8 is seen directly and/or be arranged on with being right after to falling direction.Term " directly " or " being right after " can be regarded as, and sewage directly is directed to second turn-around zone 9 from first turn-around zone 8.At this, second turn-around zone 9 tilts for first turn-around zone 8 along vertical line V read fortune.
In principle, be via turning to section 4 to realize the significantly deceleration of sewage, so that make the negative pressure relevant in input pipe keep as far as possible little with flow velocity water.But simultaneously, the resistance of pipe branches 1 should so not improve, so that in the zone that turns to section 4, causes sewage to flow backwards, and this minimizes the performance or the efficient of pipe branches 1 greatly.In other words, can cause sewage high-drag good or big big retarding to be able to compensation, so that obtain comparable volume flow or comparable performance through increasing the pipe diameter.Yet this but is disadvantageous aspect physical dimension.In order to prevent this negative effect, select dual turning to, wherein, resistance just improves via pipe branches 1 fiddling, and the deceleration of sewage is not had a negative impact.
First turn-around zone 8 has a preferred angle beta of 45 ° with respect to falling direction F or vertical line V.In other form of implementation, angle beta also can less than or greater than 45 °, for example in 30 ° to 60 ° scopes, particularly in 40 ° to 50 ° scopes.First turns to and makes the big big retarding of sewage and it is turned to towards second turn-around zone 9.
Preferably, first turn-around zone 8 is seen such setting along falling direction F, so that it extends on the whole span width of top leader section 2, thereby the entire sewage flow all strikes on first turn-around zone 8.In other words, first turn-around zone 8 is extended on the whole cross section of top leader section 2.Such first turn-around zone 8 causes forming jet S by moisture film W.Therefore, sewage clashes into second turn-around zone 9 with the form of jet S.
So be provided with respect to jet S at this with respect to falling direction F or with respect to second turn-around zone 9 of the angle [alpha] setting of vertical line V with one, so that the jet S that strikes on second turn-around zone 9 is reflected with best mode as far as possible.Under present case; Expression way " reflection " can be regarded as; Jet S leaves this second turn-around zone once more to strike angle similar on second turn-around zone 9 with it, yet is turned to like this by second turn-around zone 9 at least, thus the pressure loss then resistance through turning to maintenance as far as possible little.Thus performance just maximum volume flow under identical deceleration situation, be improved, the negative pressure cause that wherein flows does not change in input pipe 7.
Preferably, with respect to the angle [alpha] of vertical line V in 2 ° to 12 ° scopes.Angle [alpha] is selected like this, so that guarantee the best reflection of water on the inner face of wall 11.Express with angle beta, preferably, water jet S is with an angle δ at 30 ° to 50 ° relevantly, and particularly 40 ° strike on second turn-around zone 9.Angle δ is defined herein as at jet S and leaves the angle between the slope of direction and second turn-around zone 9 of first turn-around zone 8.
Second turn-around zone 9 can constitute along different directions crooked, so that also further improve the reflection of sewage.For example, it is contemplated that, be provided with one around a desired shape or cross-section portion 10 vertical, as shown in the figure with vertical line V.
We can say in a word, turn to section 4 to constitute like this, so that this turns to section to sewage very little resistance to be provided, and the deceleration of sewage is not had a negative impact at this.Under the physical dimension same case, can reach bigger volume flow thus, this has correspondingly improved the performance of pipe branches 1.
First number of degrees that turn at this greater than second number of degrees that turn to.Therefore, water on first turn-around zone 8 than on second turn-around zone 9, standing bigger speed loss.The advantage that this distribution has is that system is more stable about different volume flow operations, and this system can be configured with better mode.
Preferably, second turn-around zone 9 forms through the wall 11 of pipe branches 1.As alternative, second turn-around zone 9 also can be an individual component in pipe branches 1.
At least one input pipe section 7 is in this setting like this, so that this input pipe section access tube branches 1 on the level of second turn-around zone 9 basically.In this form of implementation, it is available always to have six input pipe sections 7.At this, have larger-diameter three input pipe sections 7 and be provided with T shape mode respectively with three the input pipe sections 7 in addition that have than minor diameter, wherein, each input pipe section 7 disposes with 90 ° of angles at this each other.Having 7 groups of larger-diameter input pipe sections preferably sees along falling direction F and is arranged on the top that has than 7 groups of the input pipe sections of minor diameter.
In Fig. 1, it can also be seen that, turn to section 4 to be divided into through-flow regional 12 and ports zone 13.Through-flow regional 12 are used to flow through the above-mentioned of sewage of managing branches 1 turns to, and port zone 13 then is used to receive the sewage that imports via input pipe section 7.Open with through-flow regional 12 minutes through a dividing wall 14 in port zone 13, and therefore stop through-flow sewage to get into port zone 13 from through-flow regional 12.Dividing wall 14 and the angled configuration of falling direction F, thus dividing wall does not influence through-flow sewage as far as possible, and in other words, does not unnecessarily reduce in second turn-around zone 9 in through-flow regional 12 cross section.One in the zone 21 of bottom leader section 5, dividing wall 14 particularly can contact with sewage under big volume flow situation and can play guide element like this.
Relevant with dividing wall 14, should also be noted that first turn-around zone 8 comprises a separately seamed edge 15, separately seamed edge is provided with like this, so that sewage passes dividing wall 14 and flows away.
Between first turn-around zone 8 and dividing wall 14, can also an optional venting channels 16 be set in dividing wall 14 additionally, in this case, through-flow regional 12 and port zone 13 between can carry out air pressure balance, as representing with arrow 17.Utilize this pressure balance prevention or reduce the mobile pressure pulse that causes in system largely, thereby further reduce the danger that in input pipe 7, forms negative pressure.Venting channels 16 preferably is set directly at the advantage that has under first turn-around zone 8, and through-flow sewage can not flow into port zone 13 through venting channels 16.
Fig. 2 and 3 illustrate respectively according to the pipe branches 1 of the second and the 3rd form of implementation ' or 1 ".Pipe branches 1 ' or 1 " also additionally comprising that a current divider 18, this current divider are seen to be arranged on along falling direction F and turn to section 4 upper reaches, is facing in the top leader section 2 of first turn-around zone 8 here.Such current divider 18 also can be arranged on the form of implementation of Fig. 1.Before sewage strikes first turn-around zone 8, utilize current divider 18 can scratch the water jacket W or the Film Flow of the wall 20 of leader section 2 along top.Therefore, the advantage that current divider 18 has is that jet S turns to lower resistance.In addition, the advantage that current divider 18 also has is through scratching Film Flow, can in the pipe branches, reduce the pulse and the pressure reduction that therefore produces of air column L.
In addition, pipe branches 1 ' or 1 " also comprise at the bypass pipe 19 shown in Fig. 2 and 3.Such bypass pipe 19 is used to be equilibrated at the pressure reduction between the corresponding site.Bypass pipe 19 is provided with like this, so that sewage can not get in the bypass pipe 19.In Fig. 2 and 3, bypass pipe 19 is seen along falling direction F and is arranged on current divider 18 downstream.As alternative, bypass pipe 19 also can so dispose, so that this bypass pipe stretches among the air column L in top leader section 2.
In Fig. 2, the air section of bypass pipe 19 connection top leader sections 2 and the port zone that turns to section 4 13,, but the corresponding pressure reduction of balance like this.In Fig. 3, the air section of bypass pipe 19 connection top leader sections 2 and bottom leader section 5, but the corresponding pressure reduction of balance like this.
It is also conceivable that a bypass line is set that it is connected to port zone 13 that turns to section 4 and the air section that is connected to bottom leader section 5 with the air section of top leader section 2.
The advantage that balance pressure reduction has is, because continual balance, even can not occur at the big pressure reduction of different parts.
It should be noted that in this point current divider 18 can use separately with bypass pipe 19 separately.For example it is contemplated that and only use current divider 18, or only use bypass pipe 19 in addition.
The pipe branches is preferably produced by a kind of plastic blown method by a kind of plastics.
