Description

Technical Field

[0001] The invention mainly relates to the technical field of valve bodies, and in particular to a pneumatic ball valve group for quantitative canning. Background Art

[0002] In chemical production, it is often necessary to quantitatively fill liquid or powder materials according to the requirements of the production process. In order to improve work efficiency, quantitative canning equipment often sets a larger flow rate for filling at the beginning of canning. In order to accurately control the total amount of filling, it is necessary to reduce the filling flow rate when the filling is about to be completed until it is full. Most of them use multiple pneumatic ball valves combined together to control the flow rate for filling.

[0003] In the invention patent application with application number CN202122361150.3 and application publication date 2022.02.18, entitled "A pneumatic ball valve assembly for quantitative canning", a first pneumatic ball valve and a second pneumatic ball valve are included. A first valve core for controlling the passage of materials is arranged inside the first pneumatic ball valve, and a second valve core for controlling the quantitative passage of materials is arranged inside the second pneumatic ball valve. A first pair of interfaces and a second pair of interfaces are arranged at the connection between the first pneumatic ball valve and the second pneumatic ball valve, and a sliding block capable of lifting and lowering movement is arranged inside the first pair of interfaces. A fixing groove for fixing the sliding block is formed inside the second interface, and the first pneumatic ball valve and the second pneumatic ball valve are detachably connected together through the cooperation between the sliding block and the fixing groove. The valve group is connected together through two pneumatic ball valves to form a valve group. The first valve core inside has a channel that can be used to control whether the material can pass through the material trough inside the valve group. The second valve core has two channels of different sizes. The large channel is used to start a large flow of material infusion. When the material is about to be filled, the second valve core is rotated to allow the material to pass through the smaller channel to achieve the purpose of quantitative filling.

[0004] During the operation of the specific embodiment, the inventor discovered the following defects: when the material is transported simply through two channels of different sizes, the flow control selection range is small, and only rough quantitative filling can be performed. When the power unit of the existing pneumatic ball valve has problems, the entire pneumatic ball valve needs to be disassembled, which affects the quantitative canning process.
