Description

Technical Field

[0001] The utility model belongs to the technical field of precision casting, and in particular relates to a leakage-proof flange type ball valve body. Background Art

[0002] A ball valve is a valve that uses a sphere with a circular through-hole as the opening and closing element, which rotates with the valve stem to achieve opening and closing. Ball valves are widely used in industries such as oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electric power, municipal services, and steel, and play a vital role in the national economy. Ball valves are mostly made of metal. Their valve bodies and bonnets are initially cast in molds and then machined. However, during the casting process, the cross-section of the valve body where the valve stem is inserted is prone to structural shrinkage, which can cause the finished valve body to fail pressure testing and leak. Utility Model Content

[0003] In order to solve the technical problem of easy leakage of valve body castings, the utility model provides a leak-proof flanged ball valve body. The internal structure of the valve body is dense and there is no risk of leakage.

[0004] In order to achieve the purpose of this utility model, the technical solution adopted by this utility model is:

[0005] A leak-proof flanged ball valve body comprises a flange, a support column, a valve core body and a valve stem connection seat arranged on the side of the valve core body, which are connected in sequence from bottom to top. Reinforcing ribs are provided on both sides of the valve body, and the reinforcing ribs extend downward from the bottom of the valve stem connection seat to the flange.

[0006] The thickness of the outer surface of the reinforcing rib from the inner wall of the support column is 3 to 5 times the thickness of the support column side wall, which effectively opens up the flow channel of the molten metal and avoids the risk of leakage caused by the loose structure at the valve stem insertion position.

[0007] Preferably, the width of the reinforcing rib is 5 to 8 times the thickness of the side wall of the support column, further ensuring the flow of the molten metal into the channel.

[0008] The outer contour of the reinforcing rib of the utility model is adapted to the outer surface of the valve body.

[0009] The beneficial effect of the utility model is that two reinforcing ribs are added on both sides of the ball valve to open up the flow channel of the molten metal, which plays the role of a shrinkage feeding channel during the casting process, has a high casting success rate, and the internal structure of the obtained valve body casting is dense and will not cause leakage.
