And the casting can have defective products due to casting defects such as sand holes and the like.
The utility model has the following contents:
in view of this, the utility model provides a steam tube bank main valve body for petrochemical industry reduces the welding seam for improving the finished product qualification rate, changes former foundry goods into the forging, makes the whole weight of valve body alleviate, and the tube bank welding seam reduces, great reduction intensity of labour.
The utility model provides a steam tube bank main valve body for petrochemical industry, this steam tube bank main valve body for petrochemical industry includes: a plurality of first valve bodies and second valve bodies of forged integral structure; wherein,
each first valve body is provided with four taps which are communicated with each other, and each second valve body is provided with six taps which are communicated with each other; and a plurality of the first valve bodies or a plurality of the second valve bodies can be combined into a tube bundle main valve body with a set number of taps at will.
Preferably, the wall thickness of the first valve body and the wall thickness of the second valve body are both 6 mm.
Preferably, the set number of taps includes: four taps of the first valve body, six taps of the second valve body, eight taps combined by two first valve bodies, ten taps combined by one first valve body and one second valve body, twelve taps combined by two second valve bodies, and fourteen taps combined by two first valve bodies and one second valve body.
Preferably, the combination mode of combining the plurality of taps is welding connection.
The utility model discloses in, through the improvement of production technology, change former foundry goods into the forging, the total weight of whole valve body also reduces to some extent, about reducing 1/3 of original valve body, the tube bank welding seam reduces, great reduction intensity of labour, the appearance is pleasing to the eye, and cost reduction has improved productivity ratio and qualification rate.
Description of the drawings:
FIG. 1 is a schematic view of a combined structure of a main valve body of a steam tube bundle used in the petrochemical industry in the prior art;
fig. 2 is a schematic structural diagram of a main valve body of a steam tube bundle for petrochemical industry according to an embodiment of the present invention.
Reference numerals:
FIG. 1: two tap valve bodies-10, eight tap main valve bodies-20 and welding seams-30;
FIG. 2: a first valve body-1 and a second valve body-2.
The specific implementation mode is as follows:
in order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The main valve body of the steam tube bundle for petrochemical industry provided by the embodiment of the application is described below with reference to the accompanying drawings.
Referring first to fig. 1, fig. 1 is a schematic view illustrating a combined structure of a main valve body of a steam tube bundle for petrochemical industry in the prior art; the valve body is formed by casting, and defective products can appear on castings due to casting defects such as sand holes. If the valve body of the tube bundle main valve is welded into a valve body with eight taps, ten taps, twelve taps and the like by adopting the valve body 10 with two taps, the more taps are used, the more welding seams are used, and the labor intensity of welding is increased. For example, eight tap main valve bodies 20 may require four separate valve bodies 10 having two taps welded together with three girth welds 30 therebetween. The welding workload is large, certain welding difficulty exists, and certain requirements are met for the welding technology of welders.
With reference to fig. 2, fig. 2 is a schematic structural diagram of a valve body of a main valve of a steam tube bundle for petrochemical industry according to an embodiment of the present invention. Steam tube bank main valve body for petrochemical industry in the embodiment of this application includes: a plurality of first valve bodies 1 and second valve bodies 2 of forged integral structure; wherein, change original casting valve body into forging, removed original valve body for improving the skirt portion of liquid metal mobility when casting, change original wall thickness from 12mm into 6 mm. About 1/3 of the original valve body is reduced, and the cost is effectively reduced.
Each first valve body 1 has four taps communicating with each other, and each second valve body 2 has six taps communicating with each other; and a plurality of first valve bodies 1 or a plurality of second valve bodies 2 can be combined into a main valve body of the tube bundle with a set number of taps at will.
The setting of the number of taps includes: four taps of the first valve body 1, six taps of the second valve body 2, eight taps combined by two first valve bodies 1, ten taps combined by one first valve body 1 and one second valve body 2, twelve taps combined by two second valve bodies 2, fourteen taps combined by two first valve bodies 1 and one second valve body 2, and the like. The combination mode of combining among the multiple taps is welding connection.
In the above embodiment, it can be seen that if the valve body of the main valve of the tube bundle is provided with four taps, the first valve body 1 can be directly adopted; if the valve body of the main valve of the tube bundle is provided with six taps, the requirement of directly adopting the second valve body 2 can be met. If the valve body of the main valve of the tube bundle is provided with eight taps, the two first valve bodies 1 are used for welding, and only one welding line is used, so that two welding lines are omitted compared with the original welding line. By analogy, the labor intensity is greatly reduced, the total weight of the whole valve body is also reduced, and about 1/3 of the original valve body is reduced. Beautiful appearance, low cost and high productivity.
The utility model discloses in, through the improvement of production technology, change former foundry goods into the forging, the total weight of whole valve body also reduces to some extent, about reducing 1/3 of original valve body, the tube bank welding seam reduces, great reduction intensity of labour, the appearance is pleasing to the eye, and cost reduction has improved productivity ratio and qualification rate.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
