For achieving the above object, the technical solution of the utility model is as follows:

A kind of radial guide-vane Spit Section, described radial guide-vane Spit Section comprises radial final stage stator and radial Spit Section, described radial final stage stator and radial Spit Section cast solid form radial guide-vane Spit Section, described radial Spit Section comprises the first guide edge, second guide edge and the 3rd guide edge, the passage that spues is formed between described first guide edge and the second guide edge, the described passage that spues is communicated with radial final stage stator, one end of described first guide edge and the second guide edge is cast on radial final stage stator, the two ends of described 3rd guide edge are all cast on radial final stage stator, described radial Spit Section is by the first guide edge, second guide edge and the 3rd guide edge and radial final stage stator cast solid.

In a preferred embodiment of the present utility model, described radial guide-vane Spit Section adopts stainless steel casting to form.

By technique scheme, the beneficial effects of the utility model are:

Traditional radial final stage stator and radial Spit Section are cast as one by the utility model, which reduce cost of production and improve assembly precision.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the radial Spit Section of individual cast and the sectional view of radial final stage stator;

Fig. 2 is sectional view of the present utility model.

Embodiment

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

See Fig. 2, the radial guide-vane Spit Section of the one that the utility model provides comprises radial Spit Section 100 and radial final stage stator 200.

Because general radial Spit Section 100 and radial final stage stator 200 are all individual casts, after having cast, then fit together, so greatly waste production material, also consume the more time, reduce working efficiency.

And the utility model is by radial Spit Section 100 and radial final stage stator 200 cast solid, forms radial guide-vane Spit Section, this saves production material, reduce cost of production, also improve assembly precision simultaneously.

Radial Spit Section 100 and radial final stage stator 200 specifically integral by die casting.

Further, the utility model adopts stainless steel material casting to form, so very corrosion-resistant, durable, improves working life.

Radial Spit Section 100 is provided with the first guide edge 110, second guide edge 120 and the 3rd guide edge 130.

First guide edge 110 and the second guide edge 120 are cast in one end of radial final stage stator 200, and the 3rd guide edge 130 is cast in the other end of radial final stage stator 200.

Form the passage 140 that spues between first guide edge 110 and the second guide edge 120, the passage 140 that spues is communicated with final stage stator 200, and it is convenient to the liquid flowed out from radial final stage stator 200 to flow on radial Spit Section 100.

First guide edge 110, the Vertical direction at its top is provided with boss 111, is provided with contact jaw 112 bottom it, and contact jaw 112 is cast into one with the end 210 of radial final stage stator 200.

Second guide edge 120, its global sections is spoon shape, the Vertical direction at the top of the second guide edge 120 is provided with boss 121, is provided with contact jaw 122 bottom it, and contact jaw 122 and radial final stage stator 200 are cast into one.

Second guide edge 120 is also provided with the fixed edge 123 that cross section is L shape.

First guide edge 110 and the second guide edge 120 are all that one end and radial final stage stator 200 are cast into one, and the 3rd guide edge 130 to be two ends be all cast into radial final stage stator 200 one.

3rd guide edge 130, is provided with contact jaw 131 and contact jaw 132 at the two ends of the 3rd guide edge 130, and contact jaw 131 is cast into one with the top 220 on radial final stage stator 200, and contact jaw 112 on contact jaw 131 and the first guide edge 110 is symmetrical.

Contact jaw 132 and radial final stage stator 200 are cast into one, and contact jaw 122 on contact jaw 132 and the second guide edge 120 is symmetrical.

3rd guide edge 130 is also provided with fixed edge 133, and on fixed edge 133 and the second guide edge 120, fixed edge 123 is symmetrical.

The utility model by the first guide edge 110, second guide edge 120 on radial Spit Section 100 and the 3rd guide edge 130 and radial final stage stator 200 cast solid, thus by radial Spit Section 100 and radial final stage stator 200 cast solid.

More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
