Abstract
The utility model relates to a paraboloid reducer, a reducing elbow and a reducer tee component, the longitudinal section of the usual reducer, reducing elbow or reducer tee is a equal-diameter circle, the variable-diameter part is not a continuous curved surface, the change from the big end to the small end is a mutant process, so that the water power loss is higher. The utility model provides a paraboloid low-resistance reducer, as well as a reducing elbow and a reducer tee both generated through grafting based on the reducer technology. The reducer is characterized in that the axial section of the reducer is a parabola plane, the cross section of the reducer is a continuous circular section gradually enlarging from the parabola opening direction, and the flow direction in the reducer is that fluid flows from the small end and flows out from the big end. As per the hydromechanics theory, the velocity profile of incompressible fluid in a round pipe during the stable streamline flowing is a parabola, that is to say, the flow velocity at the center of the pipe is the maximum, and the pipe diameter can be designed as per the moving direction of fluid, so that pipe resistance loss in the system can be effectively reduced.
Description
Technical field:
The utility model relates to a kind of lower resistance reducing and reducing elbow in the water treatment, reducing tee technology.
Background technique:
Need use the pipe fitting that becomes big specification pipeline in a large number by the small dimension pipeline in water treatment plant's pipe-line system; If we are with common reducing or reducing elbow, reducing tee; Its longitudinal plane of these pipe fittings is isometrical circle, and reduced diameter portion is not continuous curved surface, and major part becomes the process that the microcephaly is a sudden change; Its hydraulic loss is bigger; Especially in the adding in the alum system of diaphragm metering pump, because the ripple contain factor of diaphragm pump, the basal area that requires the export pipeline of diaphragm pump is 3.14 times of pump discharge basal area.In chlorination system; The chlorination pipeline is very long; The negative pressure that water sprayer produces is lower again; So also require the vacuum line system pipes resistance must be enough little, be exactly that outlet at chlorinating machine connects the vacuum line (chlorination vacuum line be sonic flow gas, can think incompressible) of a caliber than big several times of chlorinating machine outlet usually.If reducing that we make with existing technology or reducing elbow, reducing tee in order to satisfy the production needs, will increase capacity of equipment, can cause the very big waste of resource like this.
Summary of the invention:
The utility model is a kind of novel parabolic lower resistance reducing and the parabolic reducing that produces of reducing technical graft and reducing elbow, reducing tee thus.It is characterized in that the axle section of this reducing is a parabolic surface, the area of section of reducing is one and becomes big continuous circle cross section gradually along the parabola opening direction.
Can know that according to Hydrodynamics Theory incompressible fluid velocity distribution during stably stratified flow in pipe is a parabola, promptly flow velocity is maximum at the tube hub place.According to above characteristic; Parabolic reducing is done following design: parabolic surface rotates a circle the parabolic cylinder of gained as parabolic reducing carrier around its symmetry axis, then according to the parabolic cylinder major part of the required caliber intercepting of reality, microcephaly's size as reducing CONCENTRIC REDUCER size.The two end portions that connects parabolic reducing pipe still is the cylndrical surface, is designed to socket fitting type structure, and the transition junction surface of parabolic large and small head and cylndrical surface should be smooth, and MEDIA FLOW is to being to flow into from the microcephaly, and major part flows out.
Because elbow, threeway exists the quantity of liquid micelle to do random motion; Make flow velocity side shape figure become more smooth, but its shape still is similar to parabola, so can parabolic reducing technical graft be gone on reducing elbow, reducing tee; MEDIA FLOW is to advancing from the microcephaly equally, and major part goes out, and is on the big extreme direction of elbow or threeway at the Way out of medium; Design parabolic reducing, large and small bell-and-spigot pipe part, still be designed to round column structure and with arc surface with parabola and cylndrical surface smooth connection.
The beneficial effect of the utility model:
According to the design of fluid motion direction, the duct loss in the effectively reduction system.
Description of drawings:
Fig. 1 is parabolic reducing, reducing elbow and the reducing tee figure according to the principles of Fig. 2.Wherein Fig. 1 (a) is parabolic reducing, and Fig. 1 (b) is parabolic reducing elbow, and Fig. 1 (c) is parabolic reducing tee.
Fig. 2 parabola forms parabolic cylinder schematic representation after its symmetry axis rotates a circle.
Embodiment:
Below in conjunction with instance this model utility is described further:
Fig. 1 (a) is parabolic reducing, and the parabolic reducing major part of 1-is treated bell-and-spigot pipe, the parabolic reducing of 2-, and the parabolic reducing microcephaly of 3-treats bell-and-spigot pipe.
The parabola of certain parameter is processed a plane, pivot then a week, be made into parabolic cylinder; This cylinder intermediate portion of intercepting is as the large and small area of bed of reducing; Two ends are made into cylindrical body, with smooth arc surface the cylndrical surface and paraboloidal large and small the parabolic cylinder at two ends are connected into an integral body then, and this is made formpiston as carrier; Make former according to this formpiston again, form product through molded mode then.This example is the parabolic reducing of DN20/DN25.
The making of parabolic reducing elbow, the parabolic cylinder part of intercepting is made parabolic reducing earlier; Make the major part cylndrical surface again, the microcephaly cylndrical surface, curved according to the elbow different amount like 90 degree; 45 degree are curved; With arc surface the smooth integral body that is connected to of parabolic cylinder is processed formpiston, root a tree name formpiston is processed former again, can obtain the desired parameters elbow through mold pressing.This example is the parabolic reducing elbows of 90 degree DN20/DN25.
The making of parabolic reducing tee, the parabolic cylinder part of intercepting is made the parabolic reducing in two ends that threeway is symmetrical in the import central shaft earlier; Make the major part cylndrical surface of symmetry again, with the smooth connection of parabolic cylinder, two stub ends are for flowing out direction with arc surface; Make liquid entering hole roundlet cylinder; The roundlet cylinder uses partly with parabolic cylinder microcephaly that circular arc is smooth to be connected, and each several part connects as a whole, and formpiston has just been made like this; Process former according to formpiston again, promptly get the parabolic reducing tee of desired parameters through mold pressing.The flow direction is advanced from the microcephaly, and the two ends major part goes out, and microcephaly and major part axis angle can be designed to 45 degree, 90 degree or arbitrarily angled as required.This example is 90 degree DN20/DN25 reducing tees.
