Description

Technical Field

[0001] The utility model belongs to the technical field of high-platform silica sol ball valves, in particular to a high-platform silica sol ball valve. Background Art

[0002] High platform silica sol ball valve is a special type of ball valve, which is precision cast by silica sol casting process. The silica sol casting process makes the ball valve have the characteristics of high dimensional accuracy and good surface finish.

[0003] For example, the Chinese patent with publication number CN209654647U discloses a silica sol high platform ball valve, including a valve body, a valve seat and a sealing ring. The valve body and the valve seat are sealed and connected by stud bolts and nuts through a center gasket. A valve cavity is provided inside the valve body, and a ball valve is provided inside the valve cavity. A packing is provided at the contact point between the valve stem and the upper end of the valve body. A pressure cover is provided on the upper end of the packing, and the pressure cover is connected to the valve seat through an external hexagonal bolt, a stainless steel gasket and a nut. In the silica sol high platform ball valve of the utility model, the handle is turned to drive the valve stem to rotate, so that the ball valve rotates along the valve cavity. When the ball valve is embedded in the limit groove, the valve body is in a closed state. When the ball valve fits the convex block, the valve body is in an open state. The design of the ball valve is relatively different from the traditional ball-type design, which reduces the use of ball valve materials, thereby saving costs. At the same time, the structure is simple and the probability of valve body clogging is reduced. The handle is designed to be a foldable structure, and the second rotating rod rotates with the first rotating rod through a rotating shaft to reduce the space occupied by the handle.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: after the above-mentioned silica sol high platform ball valve is used, some liquid will remain in the ball core groove inside it and cannot be discharged, causing the liquid in the ball core groove of the silica sol high platform ball valve to freeze when the silica sol high platform ball valve is used in cold weather, affecting the user's use of the ball valve, and when the user removes the pipeline to inspect the above-mentioned silica sol high platform ball valve, the valve handle on the silica sol high platform ball valve may be accidentally touched without paying attention, and the closed silica sol high platform ball valve will be opened, resulting in a waste of water. In view of this, we propose a high platform silica sol ball valve. Utility Model Content
