[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems. In application scenarios such as chemical or plug valves, there are more requirements for the valve body, such as multi-port use, parameter monitoring, easy operation, etc. Currently, most products have relatively simple structures and functions.

[0018] like Figure 1-Figure 3 The figure shows a multi-tube valve body structure, comprising a union joint 1, a valve cover 2, an inner liner 3, and a valve seat 4, assembled in sequence. The union joint 1 and the valve cover 2 are axially pluggable and locked in place by rotation. The union joint 1 can accommodate connections of different sizes, similar to the connection of a fire hydrant, which is fixed by rotation to prevent reverse disengagement. The valve cover 2 and the valve seat 4 are threadedly connected and fixed at the axial end faces, providing a tight and strong sealing connection. A chamber for the inner liner 3 is formed between the valve cover 2 and the valve seat 4. The union joint 1 and the valve cover 2 are provided with an inlet axially connecting to the chamber. The valve cover 2 further includes an upper opening 5 that connects to the inlet and accommodates a sensor. The valve cover 2 has an integrally connected outlet pipe 6 in the radial direction. The outlet pipe 6 is provided with an outlet connecting to the chamber and a lower opening 7 that connects to the outlet. The upper opening 5 can accommodate a pressure gauge, i.e., a pressure gauge sensor, while the lower opening 7 can be equipped with a valve for independent control. One inlet and multiple outlets can be switched according to usage needs.

[0019] The outlet pipes 6 are symmetrically arranged on both sides of the valve seat 4, and the inner tank 3 is provided with the outlet pipes 6 and the water holes 8 corresponding to the side of the valve seat 4. The water inlet and outlet directions are perpendicular to each other, the structure is concentrated, and the space occupied is small. The inner tank 3 is rotated to adjust the water outlet direction. The outlet pipes 6 are arranged in pairs on one side of the valve seat 4, and the outlet pipes 6 have an integrally connected outlet connector 9 at the end in the water outlet direction. The outlet connector 9 has a smaller diameter than the outlet pipe 6, and the diameter is set to form a step-shaped reinforcement structure. In addition, a rib ring 10 is provided on the surface of the outlet connector 9 to facilitate the use of a multi-section pipe connection method. A sealing gasket or a sealing ring 13 can also be provided as needed. No excessive elaboration or limitation is made here.

[0020] The outer wall of the inner liner 3 and the cavity wall of the valve seat 4 are respectively provided with a convex surface and a water outlet hole of the shape and size corresponding to the water hole 8. A bracket 11 is also included, which is sleeved and wrapped around the inner liner 3 and has a hollow structure. The rotation of the inner liner 3 may cause excessive local wear after long-term use, affecting subsequent use. The bracket 11 provides support, wear resistance, and sliding, thereby facilitating the long-term use of the inner liner 3.

[0021] The bottom of the valve cover 2 is provided with a connection portion 12 that fits into the inner container 3 or bracket 11. This connection portion 12 is equipped with several sealing rings 13 and annular grooves for the sealing rings 13 to enhance sealing and prevent the medium from escaping from this area. The valve seat 4 is provided with a flange 14, which is further provided with connection holes 15 evenly distributed along the circumference. A threaded connection in the axial direction further improves sealing, creating a labyrinth seal effect.

[0022] The top sidewall of the valve cover 2 is provided with blocks 16 spaced evenly along a circular line. The bottom of the flexible joint 1 is provided with stop blocks 17 corresponding in number and spacing to the blocks 16. A chute 18 is also provided within the flexible joint 1 for the blocks 16 to flexibly engage. The blocks 16 are spaced apart by the stop blocks 17 and enter the chute 18, and the blocks 16 and the stop blocks 17 are engaged and limited in the axial direction. This is a plug-in and rotational connection that achieves the effect of locking, limiting, and sealing, similar to the connection between a fire hydrant and a fire hose.

[0023] The union 1 has a stepped structure and is equipped with several reinforcing ribs 19 on its outer wall. Both the stepped structure and the reinforcing ribs 19 enhance structural strength, but depending on the application scenario and conditions, a certain strength is required to meet usage requirements. A connecting shaft 20 is provided at the bottom of the inner liner 3, passing through the bottom of the valve seat 4 and capable of connecting to an intelligent drive device for precise control.
