Description

Technical Field

[0001] The utility model relates to the technical field of ball valve covers, in particular to a highly sealed ball valve cover and forging equipment. Background Technique

[0002] The ball valve has the function of adjusting and controlling the liquid flow. The ball valve is assembled through a ball valve cover, and at the same time, the ball valve cover needs to be forged through a forging die.

[0003] For example, the authorized announcement number "CN208778808U" is a valve cover of a forging ball valve. Although the sealing structure on the valve cover is improved, a circular trapezoidal convex structure is arranged on the sealing ring pasted thereon. When the sealing ring is extruded, the trapezoidal convex structure in the sealing area will not bulge outward due to the restraint of the groove; at the same time, a clamping convex strip that can be clamped with the groove structure on the forging ball valve body is arranged on the side surface of the trapezoidal convex structure. When the sealing ring is impacted externally, the clamping convex strip in the sealing area will also not easily break away from the ball valve body due to the restraint of the corresponding groove. However, after long-term use, the sealing ring will age under the influence of the liquid, resulting in liquid leakage of the ball valve cover and affecting the service life of the ball valve; there is still a situation of displacement and deformation when the sealing ring is squeezed by the valve cover and the valve body.

Since the motor shafts 22 are rotatably connected to the connecting blocks 23, and the sliding rods 24 are slidably connected to the fixed blocks 25, the two connecting blocks 23 can be brought closer to each other. Then, the cylinder 28 is started. As the cylinder rod 29 extends, the upper die 30 and the two side dies 26 form a die cavity 31. Then, forging fluid is injected through the feeding hole 32.
