Such a design requires two separate molds, and the processing cost is relatively high. However, if the valve body and valve cover are symmetrically arranged, the cost can be effectively reduced. Utility Model Content

[0003] The main objective of this invention is to provide a ball valve with a simple structure, tight connection, and good sealing effect that can be used for both the body and the cover.

[0004] This utility model proposes a ball valve with a shared body and cover, comprising a valve body, a valve cover, and a valve body. The valve body and the valve cover are arranged opposite to each other and have similar structures. A ball valve body is provided at the bottom of the valve body. The valve body and the valve cover are each provided with a first arc-shaped groove and a second arc-shaped groove on opposite sides, which are adapted to any semicircle of the circular ball valve body. The ball valve body is engaged between the valve body and the valve cover. The valve body has at least one annular body connection slot on the side opposite to the valve cover, and the valve cover has at least one annular body connection block on the side opposite to the valve body. The body connection slot and the body connection block cooperate to make the connection between the valve body and the valve cover tighter.

[0005] Preferably, a first inner connecting groove and a second inner connecting groove are respectively provided on the inner sides of the first arc-shaped groove and the second arc-shaped groove, and an annular limiting rubber ring is provided in the first inner connecting groove and the second inner connecting groove. The ball valve body is limited and positioned between the first arc-shaped groove and the second arc-shaped groove by the limiting rubber ring.

[0006] Preferably, the valve body has a plurality of valve body first connection holes on its outer side, and the valve body is connected to a pipe on one side through the valve body first connection holes.

[0007] Preferably, the valve cover has a plurality of valve cover first connection holes on its outer side, and the valve cover is connected to a pipe on one side through the valve cover first connection holes.

[0008] Preferably, the valve body further includes a connecting platform and a connecting rod. The connecting platform can limit and fix the connecting rod, and the connecting rod is connected to the ball valve body. The driving device can drive the ball valve body to rotate through the connecting rod.

[0009] The beneficial effects of the ball valve with a shared body and cover of this utility model are as follows: By setting valve bodies and valve covers with the same structure, it is possible to reduce mold costs, warehousing costs, design costs, and usage costs, while maintaining the same production quality and effectively improving economic benefits.

[0010] By setting a body connection slot on the valve body and a body connection block on the valve cover, the connection between the valve body and the valve cover can be made tighter and the airtightness can be improved.

[0011] The design, in which the valve body and valve cover are positioned opposite each other, makes installation relatively simple and facilitates use and maintenance.

[0012] The connection platform has better versatility and is easier to install and use as a driver. Attached Figure Description
