Three-way ball valve working principle and application advantages introduction

The three-way ball valve is a new three-way switching type regulating valve developed by integrating advanced technology at home and abroad. The standard ball has an L-shaped three-way double-port hole type to change the relative angle between the core and the pipe. It can realize different combination control for the three pipe fluids. The T-shaped channel can be used for matching action. It is suitable for liquid break, gas, Proportion adjustment and control of media such as steam.
Three-way ball valves are available in T and L versions. The three-way 4-sided seat ball valve of the T-type flow passage adopts a 4-sided valve seat and is balanced by force to ensure reliable sealing on the closed passage. The three orthogonal pipes can be connected to each other and the third channel can be cut off, and the functions of splitting and combining are mainly used for splitting, mixed flow, commutation and full opening of the three channels. The three-way four-port seat ball valve of the L three-way ball valve type L-shaped flow passage adopts a two-sided valve seat. Mainly used for commutation of flow paths. However, only two pipes that are orthogonal to each other can be connected, and the third pipe cannot be connected to each other at the same time, and only serves as a distribution.
The three-way ball valve has two and four-seat sealing structure. The valve core hole has two types of L-shaped and T-shaped structures. The control valve core rotation angle  changes the connection state of the valve core hole and the pipe port, which can realize different three pipe branches. Combination control. The three-way ball valve has a large circulation capacity, and can control gas, liquid, and steam to be more suitable for controlling high-viscosity  fiber granular fluid. Also suitable for occasions where sealing requirements are strict.
Three-way ball valves have become more and more obvious advantages in the valve product industry. The specific reasons are as follows:
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2. The structure is simple, small in size and light in weight.
3. It is compact and reliable, and has good sealing properties. It has also been widely used in vacuum systems.
4. The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.
7. Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
