Abstract
The utility model discloses a ball valve body with an outside weld, which comprises a ball valve cylinder (1) and a valve-rod shaft sleeve (3), wherein the ball valve cylinder (1) is provided with a positioning rabbet (5), the end part of the valve-rod shaft sleeve (3) is provided with a weld slot (6), and an outside weld (4) is arranged outside the ball valve cylinder (1). According to the utility model, a mode that the ball valve cylinder and the valve-rod shaft sleeve are internally welded is changed into a mode of welding the valve-rod shaft sleeve on the outside of the ball valve cylinder, so that the welding difficulty is reduced, and through the adoption of external welding, an operation of welding can be completed by using union-melt welding production equipment and the like without using manual welding, thereby greatly increasing the production efficiency; meanwhile, the outside weld formed through external welding is regular in shape, so that the quality of the weld can be conveniently detected by a detection instrument; and the ball valve body is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of valve body that is applicable to the pressure piping in petrochemical industry, rock gas, oil product field with ball valve.
Background technique
In recent years; Pressure piping as being applicable to petrochemical industry, rock gas, oil product field is used ball valve; Its valve body generally all adopts integral type to be welded; Like accompanying drawing 1, shown in 2, after soon ball valve cylindrical shell 1 will cooperate the location with valve stem sleeve 3, adopt the manual welding mode to form in ball valve cylindrical shell 1 interior welds.Because this ball valve body is an interior welds, generally all adopts the manual welding mode, welding efficiency is low; If the internal diameter of ball valve cylindrical shell is smaller; Adopt manual welding all very difficult, the difficulty of interior welds is big simultaneously, the out-of-shape of the internal weld seams 2 of formation; Be easy to generate welding slag, pore, and be not easy by through welding.Because the out-of-shape of internal weld seams 2, when detecting weldquality, detection facility is not easy to place in the ball valve cylindrical shell 1, thereby is not easy to the detection of weld seam.
The model utility content
The purpose of the utility model just is the deficiency to existing technology, and a kind of ball valve body with outside weld is provided, and it can improve the manufacturing efficiency of valve body, reduces the welding difficulty of valve body, is convenient to the quality testing of weld seam.
To achieve these goals; The technological scheme that the utility model adopts is such: a kind of ball valve body with outside weld, comprise ball valve cylindrical shell and valve stem sleeve, and it is characterized in that: have positioning spigot on the ball valve cylindrical shell; The valve stem sleeve end has the weld seam groove, and outside weld seam is in ball valve cylindrical shell outside.
As the further improvement of the utility model, described weld seam groove is monolateral V-arrangement, welds the outside weld shape of the valve body that obtains rule more like this, also saves welding consumables.
Compared with prior art; The advantage of the utility model is: the utility model changes the interior welds of ball valve cylindrical shell and valve stem sleeve into that valve stem sleeve is welded on the ball valve cylindrical shell is outside, has not only reduced the welding difficulty, and adopts outside weldings can use manufacturing mechanism such as Lincoln weld to accomplish welding; Without manual welding; Improved manufacturing efficiency greatly, externally the outside weld shape of welding formation is regular simultaneously, can make things convenient for the detection of detecting instrument butt welded seam quality; Simple in structure, easy to operate.

Fig. 4 is the side view of outside weldings ball valve body.
Marginal data:
1, ball valve cylindrical shell; 2, internal weld seams; 3, valve stem sleeve; 4, outside weld seam; 5, positioning spigot; 6, weld seam groove.
Embodiment
To combine accompanying drawing and practical implementation that the utility model is described further below.
Referring to Fig. 3, Fig. 4, a kind of ball valve body with outside weld comprises ball valve cylindrical shell 1 and valve stem sleeve 3, has positioning spigot 5 on the ball valve cylindrical shell 1, and valve stem sleeve 3 ends have weld seam groove 6, and outside weld seam 4 is in ball valve cylindrical shell 1 outside.Through positioning spigot 5; Valve stem sleeve 3 cooperates the location with ball valve cylindrical shell 1; The weld seam groove 6 of valve stem sleeve 3 ends just contacts with ball valve cylindrical shell 1 outside; Use welding equipment such as Lincoln weld that valve stem sleeve 3 and ball valve cylindrical shell 1 are welded then, the outside weld seam 4 of formation is just at the outer surface of ball valve cylindrical shell 1.
As the further improvement of the utility model, described weld seam groove 6 is monolateral V-arrangement, welds the outside weld shape of the valve body that obtains rule more like this, also saves welding consumables.
The utility model changes the interior welds of ball valve cylindrical shell and valve stem sleeve into that valve stem sleeve is welded on the ball valve cylindrical shell is outside, has not only reduced the welding difficulty, and adopts outside weldings can use manufacturing mechanism such as Lincoln weld to accomplish welding; Without manual welding; Improved manufacturing efficiency greatly, externally the outside weld shape of welding formation is regular simultaneously, can make things convenient for the detection of detecting instrument butt welded seam quality; Simple in structure, easy to operate.
Claims (2)
1. ball valve body with outside weld; Comprise ball valve cylindrical shell (1) and valve stem sleeve (3); It is characterized in that: have positioning spigot (5) on the ball valve cylindrical shell (1), valve stem sleeve (3) end has weld seam groove (6), and outside weld seam (4) is in ball valve cylindrical shell (1) outside.
2. a kind of ball valve body with outside weld according to claim 1 is characterized in that: described weld seam groove (6) is monolateral V-arrangement.
