And the heavy-calibre ball valve weight is great, because the bottom surface of the flange of its both ends and case chamber all is circular arc, so need external force to assist during the installation, prevent to incline askew, it is inconvenient to install.
Disclosure of Invention
For solving the problem that exists among the prior art, the utility model discloses a ball valve blank of the heavy-calibre that the structure is firm has been designed, the ball valve blank is the right angle three way type, and the middle part is spherical case chamber, the case chamber upwards is equipped with the control chamber, and the right side circulation chamber is established to the both sides level, the opening part in control chamber and both ends circulation chamber turns up perpendicularly respectively has integrated into one piece's flange board, and the relative medial surface of the flange board in both ends circulation chamber respectively with be connected with the strengthening rib between the chamber wall both sides in control chamber, the bottom central authorities downward protrusion in the chamber wall in case chamber has the columniform lug, the lower surface of lug and the bottom of the flange board in both sides circulation chamber are on same horizontal plane.
Furthermore, the joint of the valve core cavity and the circulation cavities at the two ends is respectively provided with a reinforcing convex column at the two sides of the ball valve blank.
Furthermore, a cylindrical cavity is arranged on the inner side surface of the control cavity close to the opening at the upper end, a cylindrical protrusion is formed on the outer side of the cavity wall of the control cavity by the cavity, the cavity is located on one side of the control cavity close to the circulation cavity, and the cavity is horizontally arranged and perpendicular to the axis direction of the two flow cavities.
Further, the cavity diameter of the control cavity on the opposite side of the cavity becomes larger.
Furthermore, a circle of convex ring is arranged at the joint of the inner side of the circulation cavity at the lower side of the concave cavity and the valve core cavity.
Furthermore, the outer sides of the two end walls of the concave cavity are respectively provided with a reinforcing bulge in the coaxial core direction.
Compared with the prior art, the utility model discloses a large-bore ball valve blank progress part of heavy-calibre lies in, sets up the strengthening rib through the medial surface of flange board, has improved the joint strength of flange board with the blank body, improves the holistic steadiness of blank, sets up simultaneously and strengthens the arch and has improved the intensity of blank self, and the bottom in case chamber sets up cylindrical lug, can directly put on ground when making things convenient for the ball valve installation, does not take place askew, simple to operate under the condition that does not have external force to support.

In the figure, 1 control cavity, 2 valve core cavity, 3 left circulation cavity, 4 right circulation cavity, 5 flange plate, 6 reinforcing ribs, 7 convex block, 8 reinforcing convex column, 11 concave cavity, 12 reinforcing convex block and 41 convex ring
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the present invention are clearly and completely described, and the described embodiments are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the utility model discloses an embodiment of a ball valve blank of heavy-calibre has been designed, and the ball valve blank is the three way type, including integrated into one piece's control chamber 1, case chamber 2, left circulation chamber 3 and right circulation chamber 4, wherein the vertical upside that sets up and case chamber 2 in control chamber 1, left circulation chamber 3 and right circulation chamber 4 are located the left and right sides in case chamber 2 respectively, and the two is on same horizontal axis.
The openings of the control cavity 1, the left circulation cavity 3 and the right circulation cavity 4 are respectively and vertically turned outwards to form a circle of flange plates 5. Wherein, a reinforcing rib 6 is connected between the opposite inner side surfaces of the left circulation cavity 3 and the right circulation cavity 4 and the cavity wall of the control cavity 1 respectively.
The right side cavity wall of control chamber 1 evaginates and forms cavity 11 to form the columniform arch in the outside of control chamber 1 cavity wall, cavity 11 level sets up, square perpendicular with the axle center of circulation chamber, is equipped with columniform and strengthens protruding 12 respectively in the outside of the both ends wall of cavity 11. The cavity diameter of the lower part of the left side of the control cavity 1 is enlarged, and the cavity diameter of the most part is arranged downwards towards the left flow cavity 3.
The junction of the inner side of the right circulation cavity 4 and the valve core cavity 2 is provided with a circle of convex ring 41, the outer sides of the cavity walls of the junction of the left circulation cavity 3, the right circulation cavity 4 and the valve core cavity 2 are respectively provided with a reinforcing convex column 8, and the junctions of the front side and the rear side of the ball valve blank are respectively provided with the reinforcing convex columns 8.
In addition, a cylindrical bump 7 is arranged at the center of the bottom side of the ball valve blank, and the bottom surface of the bump 7 and the bottommost ends of the flange plates 5 of the circulation cavities on the two sides are positioned on the same horizontal plane.
