Abstract
The utility model relates to a ball valve shell casting. The ball valve shell casting comprises a body, wherein a through hole is formed in the body. The through hole is divided into an inner spherical surface segment, a first circular hole segment and a second circular hole segment in sequence from one end to the other end. The first circular hole segment and the second circular hole segment are arranged concentrically, and the center line of the first circular hole segment and the center line of the second circular hole segment pass the center of the inner spherical surface segment. The diameter of the outer end of the inner spherical surface segment is larger than the diameter of the end, connected with the first circular hole segment, of the inner spherical surface segment. The joint between the inner spherical surface segment and the first circular hole segment is in a slope transition mode. The diameter of the first circular hole segment is larger than that of the second circular hole segment, so that a step is formed at the joint between the first circular hole segment and the second circular hole segment. The ball valve shell casting is characterized in that reinforcing blocks are evenly distributed on the periphery of the portion, corresponding to the step of the through hole, of the body, and the reinforcing blocks and the body are formed into a whole in a casting mode. By the adoption of the ball valve shell casting, the strength of the body can be improved, the body is not prone to cracks, and a ball valve is not prone to being damaged.
Description
Technical field
The utility model relates to a kind of metal ceramic, the ball valve shell foundry goods for the manufacture of ball valve specifically.
Background technique
So-called ball valve, refers to making open-shut device with the spheroid of manhole, and spheroid rotates with valve rod, to realize the valve of switching motion.Along with scientific and technical develop rapidly, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.Ball valve adopts metal to make mostly, and its housing need to utilize die casting to become foundry goods at the manufacture initial stage, then foundry goods is being processed and is being made.
Traditional ball valve shell foundry goods all comprises body, on body, there is through hole, through hole is divided into inner ball surface section, the first circular hole portion and the second circular hole portion successively from its end to end, and the first circular hole portion and the second circular hole portion are arranged concentric, and its center line is through the center of circle of inner ball surface section; The outer end diameter of inner ball surface section is greater than the diameter of itself and the first circular hole portion connecting end, and inner ball surface section and the first circular hole portion joint are chamfered transition, and the diameter of the first circular hole portion is greater than the diameter of the second circular hole portion, makes both joints form step.This ball valve shell foundry goods, the step place in its through hole easily forms stress and concentrates, and makes this casting strength lower, and when following process or use, this place easily cracks, and causes the damage of ball valve.
Model utility content
Problem to be solved in the utility model is to provide a kind of ball valve shell foundry goods, adopts this foundry goods, can improve body intensity, makes it be difficult for cracking, and is difficult for causing ball valve to damage.
For addressing the above problem, take following scheme: ball valve shell foundry goods of the present utility model comprises body, has through hole on body.Described through hole is divided into inner ball surface section, the first circular hole portion and the second circular hole portion successively from its end to end, and the first circular hole portion and the second circular hole portion are arranged concentric, and its center line is through the center of circle of inner ball surface section.The outer end diameter of described inner ball surface section is greater than the diameter of itself and the first circular hole portion connecting end, and inner ball surface section and the first circular hole portion joint are chamfered transition.The diameter of described the first circular hole portion is greater than the diameter of the second circular hole portion, makes both joints form step.Be characterized in that body periphery corresponding to described through hole step place is evenly equipped with reinforced block, reinforced block is all cast into one with body.
Further improvement of the utility model scheme is that body periphery corresponding to described inner ball surface section outer end has flange edge, and this flange edge is along being circumferentially evenly equipped with bolt hole, and the axis of bolt hole is all parallel with the center line of described through hole.Flange edge and bolt hole are convenient to ball valve shell and are connected with other parts when follow-up use, and bolt hole generation when casting, can reduce the consumption of raw material, reduce the workload of following process operation simultaneously.
Take such scheme, have the following advantages: because the diameter of through hole first circular hole portion of ball valve shell foundry goods of the present utility model is greater than the diameter of the second circular hole portion, make both joints form step, and body periphery corresponding to this step place is evenly equipped with reinforced block, and reinforced block is all cast into one with body.The body periphery corresponding at through hole step place arranges reinforced block, can balance portion stress, and increase the intensity at this place, thereby make the slight raising of foundry goods integral body, in following process or while using, be difficult for cracking, be also difficult for causing the damage of ball valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of ball valve shell foundry goods of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, ball valve shell foundry goods of the present utility model comprises body 1, on body 1, has through hole.Described through hole is divided into inner ball surface section 2, the first circular hole portion 3 and the second circular hole portion 8 successively from its end to end.So-called inner ball surface section 2, the internal surface of this section of through hole is sphere.The first circular hole portion 3 and the second circular hole portion 8 are arranged concentric, and its center line is through the center of circle of inner ball surface section 2.The outer end diameter of described inner ball surface section 2 is greater than the diameter of itself and the first circular hole portion 3 connecting ends, and inner ball surface section 2 and the first circular hole portion 3 joints are chamfered transition.The diameter of described the first circular hole portion 3 is greater than the diameter of the second circular hole portion 8, makes both joints form step 4.Body 1 periphery corresponding to described through hole step 4 places is evenly equipped with reinforced block 7, and reinforced block 7 is all cast into one with body 1.Body 1 periphery corresponding to described inner ball surface section 2 outer ends has flange edge 6, and this flange edge 6 is along being circumferentially evenly equipped with bolt hole 5, and the axis of bolt hole 5 is all parallel with the center line of described through hole.
Described bolt hole 5 is all directly to cast when this ball valve shell cast casting, can reduce like this use amount of casting material, also can reduce the workload of following process operation.
