Description
Technical field
the utility model relates to a kind of combined type spherical shell bifurcated pipe that is used for the water lift pumping plant, belongs to the bifurcated pipe technical field that water supply line merges or diverges.
Background technique
water lift pumping plant generally is provided with 2 above water pump assemblies.For the pumping plant of multicomputer, long pipeline, often adopt the bifurcated pipe parallel pipeline, this can not only save pipeline investment, and velocity in pipes is obviously reduced can under small flow, move the time, and the minimizing line loss reaches the purpose of energy saving.The internal diameter of pumping plant outlet pipe is generally 500～1000mm scope, and the pattern of at present used parallel large-scale bifurcated pipe mainly is right-angle tee, crescent moon rib bifurcated pipe, foretells shape bifurcated pipe etc., generally all adopts the fabrication and installation of steel plate field welding to form.The production method of this large-scale bifurcated pipe of the prior art exists following shortcoming: 1, right-angle tee and fore-telling shape bifurcated pipe are owing to structural reason, and voltage endurance capability is low, only is applicable to the low water head situation; 2, because of the bifurcated pipe build is big inadequately, need to adopt the on-the-spot artificial welding production of fritter steel plate, owing to luminal space is little, welding condition is poor, and constructional difficulties, quality are difficult for guaranteeing, and construction cost is high, and steel, welding rod waste are greatly.3, the construction process of on-the-spot weldering system must cause the plate joint many, the internal surface poor flatness, and loss of head is big, on-the-spot antirust imprecision, working life is short.4, the factory that does not have the member of producing this type of size in the market, if produce whole bifurcated pipe in that factory is customized, then build is excessive, transportation is installed inconvenient, and easy deformation in the handling process, influences bearing capacity.5, right-angle tee, crescent moon rib bifurcated pipe, these several kinds bifurcated pipe patterns commonly used of fore-telling shape bifurcated pipe generally are suitable for the pumping plant of two water pumps, and 3 water pumps then divide the two-stage bifurcated pipe to arrange at least, and 5 water pumps then divide three grades of bifurcated pipes layouts at least.Occupied ground, loss of head and engineering cost will be multiplied.So the production method of existing large-scale bifurcated pipe and structure still are not ideal enough.
Summary of the invention
The purpose of
the utility model is; Provide a kind of transportation, easy for installation, hydraulics good, the body stress condition is good, load performance is high, long service life, and can be widely used in the combined type spherical shell bifurcated pipe that is used for the water lift pumping plant of basic, normal, high hydraulic head pressure, thereby overcome the deficiency of existing technology.
The technological scheme of
the utility model is to constitute like this: a kind of combined type spherical shell bifurcated pipe that is used for the water lift pumping plant of the utility model is: this combined type spherical shell bifurcated pipe comprises two and half housings; The edge of two and half housings is provided with adpting flange, and two and half housings are connected with bolt through adpting flange.
aforementioned combined type spherical shell bifurcated pipe that is used for the water lift pumping plant, said half housing comprise a hemispherical Shell and one and half persons in charge and at least two half arm; Half person in charge all is connected with hemispherical Shell with half arm.
aforementioned combined type spherical shell bifurcated pipe that is used for the water lift pumping plant, the joint of said half person in charge and half arm and hemispherical Shell is provided with buttress brace.
aforementioned combined type spherical shell bifurcated pipe that is used for the water lift pumping plant is provided with seal arrangement between the adpting flange on said two and half housings.
aforementioned combined type spherical shell bifurcated pipe that is used for the water lift pumping plant, said seal arrangement are the grooves that can coincide that is provided with symmetry at the interface of the adpting flange of two and half housings, are provided with seal ring in the groove.
aforementioned combined type spherical shell bifurcated pipe that is used for the water lift pumping plant, said half housing and adpting flange are processed with steel.
Owing to adopted technique scheme, the utility model compared with prior art the utlity model has following advantage:
1, employing two troubles or three trouble designs can significantly reduce the layout place when many water pumps parallel connections, economical with materials is energy-saving and cost-reducing, significantly reduces initial outlay and later stage operating cost.
2, adopted the spherical shell bifurcated pipe that mould is rolling or found, inner wall smooth, load performance is good, and hydraulics is good;
3, whole bifurcated pipe is divided into two is divided into two and half housings and carries out pre-formedly,, make simple though structure is complicated; Be convenient to bifurcated pipe inner polishing and preservative treatment, save material, fabricating cost is low; Convenient transportation, on-the-spot only need two and half housings being linked together with bolt and nut gets final product, and can simplify construction at narrow scene; Remarkable benefit, highly versatile;
4, the interface of the adpting flange of two and half housings is provided with the groove that can coincide of symmetry; Be provided with the higher seal ring of hardness in the groove; Seal ring plays positioning device simultaneously, makes the bifurcated pipe installation in position be easy to just realize the tight connecting of two hemispherical Shells;
5, adopt pre-formedly, need not field welding, can not destroy the anticorrosion structure of steel, make whole bifurcated pipe long service life, safeguard simple because of field welding.
in sum; The utility model can conveniently be applied to the situation of two pipe unifications, three pipe unifications, if divide two stage arrangement, then can satisfy the parallelly connected requirement of 9 water pumps at most; Significantly reduce and arrange the place; Simplify construction sequence, reduce engineering cost, and reduce operating cost greatly with its good hydraulics.
