Abstract
The invention provides an injection confluence tee joint for a hot water heating system, which can balance the flow and resistance of each loop of a circulating pipeline system. It is composed of a three-way shell and a tapered elbow which turns 90 degrees. The tapered elbow is located at the end of the branch pipe perpendicular to the junction pipe and has a portion extending into the junction pipe with the elbow outlet oriented in the same direction as the axis of the junction pipe. The closed circulation pipeline system is suitable for liquid media.
Description
The present invention relates to a kind of three-way pipe for pilot fluid and confluence that can impel each loop traffic of cycle cooling plating drum and resistance balance.Be applicable to the closed cycle pipe-line system of liquid medium, be specially adapted to hot water system.
Existing closed cycle pipe-line system, the described hot water heating pipe-line system of heating ventilator design handbook for example, always adopt common tee pipe fitting, no matter be that the tee pipe fitting with a kind of structure is all adopted in diversion three-way on the hot-water line or the threeway of confluxing on the return pipe, see shown in the structural material handbook.When hot water circuit, loop resistance far away is big because near-ring road pipe resistance is little, so just be far longer than the overbottom pressure that loop far away is returned by the overbottom pressure that medium had behind the near-ring road, in two loop concourses-threeway place of confluxing big overbottom pressure tributary just taking place seriously hinders flowing of little overbottom pressure tributary, the result reduces the tributary flow of little overbottom pressure loop, stops it to flow even.
Existing threeway only is the binding chamber of three mouths, the dynamic pressure direction in the tributary that overbottom pressure is big (flow velocity direction) is perpendicular to the flow direction of convergence tube medium, make it change 90 ° of directions and in convergence tube, a reaction force must be arranged, this power just in time flow direction with another tributary is opposite, Here it is hinders the main cause that another tributary flows into convergence tube, so the big more then resistance to another tributary of the tributary flow that overbottom pressure is big is also big more, even has stoped the inflow in another tributary fully.The tributary static pressure that overbottom pressure is big is also big simultaneously, and according to hydromechanical principle, total head=dynamic pressure+static pressure is so static pressure also is to hinder the reason that another tributary flows into.Prior art is by turning down the valve of the big loop arm of overbottom pressure, consume excessive part overbottom pressure, the flow and the pressure on itself and another overbottom pressure circlet road are averaged out, and this way had both slatterned the reallocation that this part energy can cause flow in each loop, the aperture of promptly transferring some loop valves has influence on the changes in flow rate of other loops, the disadvantage that just interferes with each other between the loop at once.
The objective of the invention is to provide a kind of three-way pipe for pilot fluid and confluence that can impel each loop traffic of hot water heating pipe-line system and resistance balance, make full use of the overbottom pressure energy of each loop, making the overbottom pressure that does not wait between each loop is not mutual obstruction, but the three-way pipe for pilot fluid and confluence of introducing mutually and promoting.
The objective of the invention is to realize by following proposal.A kind of three-way pipe for pilot fluid and confluence that is used for hot water system, comprise a threeway shell, one fixing elbow is set in the described threeway shell, the parallel axes of described elbow inlet is in big overbottom pressure arm axis and perpendicular to the convergence tube axis, the parallel axes of described elbow outlet is in the convergence tube axis, little overbottom pressure arm is coaxial with convergence tube, it is characterized in that described elbow is a convergent shape by inlet to the cross section that exports, the convergent elbow that utilization is communicated with big overbottom pressure arm exports the fluid of lower pressure in the little overbottom pressure arm of elevated pressures fluid injection that penetrates and meets in the convergence tube, in order to the pressure difference between each loop of balance hot water system.
In the three-way pipe for pilot fluid and confluence that is made up of threeway shell and elbow, it is one 90 ° or near 90 ° convergent elbow perpendicular to the arm end of convergence tube.This elbow part stretches in the convergence tube, and it exports towards identical with the convergence tube axis.Guiding and contraction when tributary by 90 ° of convergent elbows with big overbottom pressure, dynamic pressure raising and static pressure reduce, the tributary that this strand strengthened speed is poured when flowing to identical convergence tube and is advanced with regard to having promoted the medium in the convergence tube, simultaneously also since when pouring convergence tube static pressure reduced, then help another tributary and flow into convergence tube, reached the big little arm medium of arm medium injection overbottom pressure of overbottom pressure and converged the purpose of advancing together jointly.
Hot water system as shown in Figure 1 is an exemplary of liquid medium closed cycle pipe-line system, and the arrow among the figure indicates the media flow direction.Giving everywhere radiator buy a house in installments heating as thermal medium with the heat of boiler with water uses, because each building is different from the distance of boiler room, each radiator of same interior of building is also different from the distance of entrance, so the resistance size of carrying the heating agent process to be produced is greatly different, the hot water flow of the nearly little radiator of resistance of distance is just big, and radiator is just awfully hot; Otherwise the hot water flow of radiator is just little, and radiator is just not too hot.The present invention has overcome this shortcoming just, and the present invention utilizes the big overbottom pressure on near-ring road to come the little overbottom pressure of injection loop far away, makes that pressure reduction obtains balance between the loop.Prior art is to calculate the back pipe arrangement according to hot water flow and duct length, and utilizes the valve opening degree size of each loop to come the needed circulating load of balance, and the shortcoming of this method is:
1. effect is passive, consumes a part of overbottom pressure energy by closing minor valve, tries to achieve loop balance with the waste energy.
2. in the pipe-line system of many loops parallel connection, the valve that turns down any loop all can cause the reallocation of the flow of other loops, i.e. phase mutual interference is very big, accomplishes that desirable assignment of traffic is unlikely.
Design of the present invention and purpose will and can further be understood in conjunction with the accompanying drawings by following examples.
Accompanying drawing 1 is the use-case-hot water heating closed cycle piping diagram of three-way pipe for pilot fluid and confluence.
Accompanying drawing 2 is the longitudinal sectional views according to the three-way pipe for pilot fluid and confluence of a most preferred embodiment of the present invention.
Accompanying drawing 3 is longitudinal sectional views of the three-way pipe for pilot fluid and confluence of another embodiment of the present invention.
Referring to figs. 1 through 3, number description is as follows: [1] three-way pipe for pilot fluid and confluence, [2] diversion three-way, [3] radiator, [4] circulating water pump, [5] water-heating boiler, [6] swelling water tank, [7] floating ball valve of rehydration, [8] automatic control pressure vent, [10] three-way pipe for pilot fluid and confluence shell, [11] big overbottom pressure arm, [12] convergent elbow, [13] retainer ring, [14] elbow outlet, [22] little overbottom pressure arm, [33] convergence tube.
After the big near-ring road medium of overbottom pressure enters arm [11], contraction and 90 ° of guiding through convergent elbow [12], improve dynamic pressure and reduced static pressure, promptly be flushed in the convergence tube [33] with bigger flow velocity, promoted advancing of original medium, it also is favourable that static pressure reduction simultaneously flows into convergence tube [33] for the medium in the arm [22].This shows that though two bursts of overbottom pressure differences that the tributary has, through behind the three-way pipe for pilot fluid and confluence, the energy that the tributary that overbottom pressure is little has absorbed the big tributary of overbottom pressure has converged into mixed flow.
