Description

Technical Field

[0001] The utility model relates to the technical field of valve components, in particular to a cast component of a propeller-type ball valve. Background Art

[0002] The metal hard-sealed ball valve closes the valve by rotating the spherical flow body. When the penetration surface of the spherical flow body rotates to a direction parallel to the pipeline, the hard-sealed ball valve and hard-sealed butterfly valve, as a component used to achieve on-off and flow control of the pipeline system, have been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower, etc.

[0003] In the patent with the publication number CN212718111U, a kind of expanded metal hard seal ball valve casting is proposed, which includes a threaded rod, a first oblique slider, a second oblique slider, a left ball flap, a right ball flap and a limit plate. The motor drives the threaded rod to rotate, and the thread drives the flow body to rise. During the rising process, the flow body drives the right ball flap to move to the left and the left ball flap to move to the right respectively through the first oblique slider and the second oblique slider, and then the hand wheel is turned to drive the upper transmission rod to rotate, and the flow body starts to rotate, which avoids the left ball flap and the right ball flap from rubbing against the inner wall of the valve body, and solves the problem that the ball flap inside the current metal hard seal ball valve is easy to rub against the inner wall of the valve when rotating, resulting in sealing failure and leakage. However, there are still the following problems in this patent:

[0004] The above-mentioned ball valve has a relatively complex structure during use, and long-term friction will produce gaps, resulting in poor sealing effect, making it inconvenient to use.

[0005] In view of the above problems, it is necessary to design a kind of expansion type ball valve casting to overcome the above problems. Utility Model Content
