Description

Technical Field

[0001] The utility model relates to the technical field of valve body castings, in particular to a safety valve body casting. Background Art

[0002] Valve body castings are one of the main components used in valve manufacturing. They are formed by melting metal and pouring it into a mold through a casting process. Valve body castings often have complex internal and external shapes to ensure the proper function of the valve and fluid control functions. Valve body castings are susceptible to cracking due to factors such as material quality, manufacturing quality, and temperature.

[0003] The existing patent application number CN202123407546.3 discloses a crack-resistant valve body casting. Multiple reinforcing ribs are integrally cast with the valve body, reinforcing and protecting the valve body, allowing it to better withstand the impact of fluid in the pipeline, thereby increasing its service life and usability. However, the use of a single reinforcing rib cannot effectively protect the valve body. The valve body is prone to collisions during transportation or improper installation, which can cause the valve body to crack.

[0004] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0008] The anti-cracking structure includes a group of upper clamps, a group of lower clamps, several reinforcing plates, a group of locking wrenches, a group of nuts, a group of screws, a group of locking rings and a group of hooks. A group of upper clamps is sleeved on both ends of the valve housing, a group of lower clamps is sleeved on both ends of the valve housing, and corresponds to the position of a group of upper clamps. Several reinforcing plates are respectively installed between the relative group of upper clamps and the relative group of lower clamps.

[0021] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1-6As shown: A safety valve body casting, including a valve housing 1 and a group of connecting rings 2 fixedly connected to the two ends of the valve housing 1, the valve housing 1 is externally sleeved with an anti-cracking structure; the anti-cracking structure includes a group of upper clamps 3, a group of lower clamps 4, a plurality of reinforcing plates 5, a group of locking wrenches 6, a group of nuts 7, a group of screws 8, a group of locking rings 9 and a group of hooks 10, a group of upper clamps 3 are sleeved on both ends of the valve housing 1, a group of lower clamps 4 are sleeved on both ends of the valve housing 1, and the position of the group of upper clamps 3 corresponds to that of the group of lower clamps 4, a plurality of reinforcing plates 5 are respectively installed between the relative group of upper clamps 3 and the relative group of lower clamps 4, a A group of locking wrenches 6 is hinged at the front end of a group of upper clamps 3, a group of nuts 7 is hinged in a group of locking wrenches 6, a group of screws 8 are threadedly inserted in a group of nuts 7, a group of locking rings 9 are installed at the front end of a group of screws 8, a group of hooks 10 are installed at the front end of a group of lower clamps 4, and a group of locking rings 9 are respectively suspended in the corresponding hooks 10; the rear ends of a group of upper clamps 3 and lower clamps 4 are movably hinged through a pin 11; a group of upper clamps 3 and a group of lower clamps 4 are respectively installed with reinforcing plates 12; a group of screws 8 are respectively installed with limiting blocks 13 at the rear ends; a group of connecting rings 2 are evenly opened with a number of connecting holes 14.
