Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel fluorine-lined three-way ball valve. Background Art

[0002] Since the beginning of the 21st century, the global petrochemical industry has gradually shifted to China. China has become a major producer of petrochemical products, with crude oil processing capacity and ethylene production capacity now ranking second and third in the world, respectively, and continuing to grow. However, my country has long relied on imports for petrochemical equipment, including specialized valves for key processes. Imported valves are not only expensive but also extremely inconvenient to replace during maintenance. Therefore, it is the unshirkable responsibility of the Chinese valve industry to focus on independent innovation, develop high-end valves, and replace imported ones with imported ones.

[0003] Fluoroplastic-lined valves began development in the 1970s. Due to the specialized nature of their structure, the initial designs primarily focused on simple butterfly and ball valves, which were not suitable for handling strong acids, bases, and solvents in petrochemical pipelines. Later, Hastelloy, Monel, and nickel-based alloys were developed to address the challenges of specialized petrochemical pipeline transportation. However, these alloys contain significant amounts of precious metals such as Ni, Cr, Nb, and Ti. Coupled with limited resources and high costs, fluoroplastic-lined valves became an ideal alternative to precious metal valves. Fluoroplastic-lined valves are a product of modern scientific and technological advancements.

[0004] At the same time, the existing fluorine-lined three-way ball valve is formed by fluorine lining inside the carbon steel valve. Its structure and working principle are exactly the same as those of the steel valve. During use, it cannot achieve the functions of diversion and confluence and distribution in different directions. For this reason, we propose a new type of fluorine-lined three-way ball valve. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a novel fluorine-lined three-way ball valve.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A new type of fluorine-lined three-way ball valve is designed, including a right two-way valve body and a left valve body, which are fixedly connected by bolts and nuts, and valve seat sealing rings are installed on the outside of the internal channels of the right two-way valve body and the left valve body, and a ball with a handle is placed inside the right two-way valve body and the left valve body, and the ball with the handle conflicts with the valve seat sealing ring, the top of the ball with the handle passes through the right two-way valve body and is fixedly sleeved with a handle, a stuffing box is fixedly installed on the top of the right two-way valve body, and the top of the ball with the handle passes through the stuffing box, and F packing sleeved on the outside of the ball with the handle is placed inside the stuffing box, and a packing gland is sleeved on the outside of the ball with the handle, and the lower end of the packing gland conflicts with the F packing.

[0008] Preferably, the ball with handle includes a valve core, a valve hole is opened on one side of the valve core, a valve handle is fixedly installed on the top of the valve core, the valve handle is fixedly connected to the handle, and the valve handle passes through the packing gland, F packing, and the stuffing box.

[0009] Preferably, the two channels of the right two-way valve body are perpendicular to each other.

[0010] Preferably, the valve core has a C-shaped structure.

[0011] The novel fluorine-lined three-way ball valve proposed in this utility model has the following advantages: It utilizes a right-hand two-way valve body to achieve flow path switching to meet the needs of different operating conditions. It can interconnect three orthogonal pipelines and cut off the third channel, thereby achieving the functions of diverting, merging, and distributing flow in different directions. In specific applications, it can reduce the number of valves and pipe fittings used in the system, saving space, simplifying operation, and greatly reducing the possibility of misoperation.

[0012] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
