[0015] Example 1

[0016] As Figure 1 shown, the main components of the device include:

[0017] (1) The decorative cover 1 is a circular or square flat plate with a recess or through hole in the center matching the top of the handle, and the edge is provided with a mounting hole matched with the cross screw. It beautifies the appearance of the valve, protects the top of the handle from damage by external force, and provides additional fastening effect. It is fixed on the top of the handle 3 by cross screw 2.

[0018] (2) Cross screw 2: standard cross slot cylindrical head screw with specified thread length and diameter. The decorative cover 1 is fixed on the handle 3 to ensure firm connection between the two. It is screwed into the threaded hole on the top of the handle 3 through the mounting hole of the decorative cover 1.

[0019] (3) Handle 3: cylindrical or rectangular, with a through hole or recess in the center matching the valve stem 4, and a mounting surface on the top matching the decorative cover. It provides an interface for user operation, and controls the up and down movement of the valve stem by rotating or pushing the handle, so as to open or close the valve. It is fixed with the valve stem 4 by welding, threaded connection or buckle, and the top is connected with the decorative cover 1 by cross screw 2.

[0020] (4) Valve stem 4: An elongated cylindrical rod with a threaded or snap-fit structure at the bottom to match the valve port on the top of the three-way valve ball and a hole or slot at the top to connect with the handle. The rotation or push-pull action of the handle is transmitted to the three-way valve ball to control the opening and closing of the valve. It is connected to the top valve port of the three-way valve ball 6 through threaded connection, snap or welding, etc., and is connected to the handle 3 through the hole or slot at the top.

[0021] (5) O-ring 5: A circular rubber ring with specific cross-sectional dimensions and hardness. It provides a seal between the valve stem and the three-way valve ball to prevent fluid leakage. It is installed at the connection between the valve stem 4 and the top valve port of the three-way valve ball 6, and achieves sealing by extrusion deformation.

[0022] (6) Three-way valve ball 6: A spherical valve body with three passages, each with a valve port, which can be controlled by rotation to control the opening and closing of the passage. It controls the flow direction and flow rate of the fluid, and achieves switching or cutting off between different fluids. It is connected to the drain valve body 8 and locking cap 10 through threaded connection, welding or snap, etc., and is connected to the valve stem 4 through O-ring 5 at the top.

[0023] (7) Sealing ring 7: An annular rubber or plastic part with specific cross-sectional dimensions and elasticity. It provides a seal between the drain valve body and the bottom valve port of the three-way valve ball to prevent fluid leakage. It is installed at the connection between the drain valve body 8 and the bottom valve port of the three-way valve ball 6, and achieves sealing by extrusion deformation.

[0024] (8) Drain valve body 8: Generally cylindrical or conical, with a fluid outlet at the bottom and a connection to the bottom valve port of the three-way valve ball at the top. As an outlet passage for fluid, it is controlled by the three-way valve ball to achieve fluid discharge or cutoff. It is connected to the bottom valve port of the three-way valve ball 6 through threaded connection, welding or snap, etc.

[0025] (9) O-ring 9: Similar to O-ring 5, but with different dimensions and installation locations. It provides a seal between the side valve port of the three-way valve ball and the locking cap to prevent fluid leakage. It is installed at the connection between the side valve port of the three-way valve ball 6 and the locking cap 10, and achieves sealing by extrusion deformation.

[0026] (10) Locking cap 10: Generally cylindrical or hexagonal, with a threaded or snap-fit structure inside to match the side valve port of the three-way valve ball. By rotating the locking cap, the opening degree of the side valve port of the three-way valve ball can be fixed or adjusted, while providing additional sealing effect. It is connected to the side valve port of the three-way valve ball 6 through threaded connection or snap, etc.

[0027] The working mode of the device is as follows: (1) Initial state: The valve is in the closed state, and each valve port of the three-way valve ball is closed, so the fluid cannot flow.

[0028] (2) Opening Operation: The user rotates or pushes / pulls the handle 3, which drives the valve stem 4 to rotate or move. The part of the valve stem connected to the top valve port of the three-way valve ball 6 via the O-ring 5 rotates or moves accordingly. According to the design of the three-way valve ball, rotating or moving the valve stem will open or close a specific channel. For example, when water needs to be drained, the handle can be rotated to connect the bottom valve port of the three-way valve ball with the drain valve body 8.

[0029] (3) Sealing function: O-ring 5, sealing ring 7, and O-ring 9 are respectively installed between the valve stem and the top valve port of the three-way valve ball, between the drain valve body and the bottom valve port of the three-way valve ball, and between the side valve port of the three-way valve ball and the locking cap. These seals achieve tight connection and sealing between the various parts of the valve through compression deformation, preventing fluid leakage.

[0030] Example 2

[0031] Based on Example 1, such as Figure 1 As shown, the working principle of this integrated valve is based on the rotation control of the three-way valve ball and the compression sealing of the sealing element. The specific working principle is as follows:

[0032] (1) Rotation control: When the user needs to control the flow direction or flow rate of the fluid, the handle 3 is rotated, which drives the valve stem 4 to rotate. The rotational movement of the valve stem 4 is transmitted to the top valve port of the three-way valve ball 6 through the O-ring 5. Since the three-way valve ball 6 has a specific channel and valve port inside, rotating the valve stem will change the communication state between the internal channel of the three-way valve ball and the drain valve body 8 and the locking cap 10, thereby realizing the flow direction control and flow rate regulation of the fluid.

[0033] (2) Sealing Mechanism: O-ring 5, sealing ring 7, and O-ring 9 are respectively installed between the valve stem and the top valve port of the three-way valve ball, between the drain valve body and the bottom valve port of the three-way valve ball, and between the side valve port of the three-way valve ball and the locking cap. These seals are made of elastic material. When the valve stem, drain valve body, or locking cap comes into contact with the three-way valve ball, the seals are compressed and undergo elastic deformation, thereby filling the tiny gaps between the components and achieving a tight seal. This sealing mechanism effectively prevents fluid leakage when the valve is closed.

[0034] (3) Fluid control: When a specific channel of the three-way valve ball is opened, fluid will flow along that channel. For example, when water needs to be drained, rotating the handle connects the bottom valve port of the three-way valve ball with the drain valve body 8, and fluid will flow out from the outlet of the drain valve body. At the same time, the flow rate can be controlled by adjusting the rotation angle of the handle.

[0035] Example 3

[0036] Based on Example 1, such as Figure 1 The following is a detailed implementation method of this integrated valve:

[0037] (1) Material selection: Key components such as valve stem 4, three-way valve ball 6, drain valve body 8, and locking cap 10 are made of corrosion-resistant and high-strength metal materials, such as stainless steel or alloy steel. Sealing elements such as O-ring one 5, sealing ring 7, and O-ring two 9 are made of elastic and wear-resistant rubber or plastic materials.

[0038] (2) Structure design: Three-way valve ball 6 is designed as a spherical valve body with three passages, each with a valve port. Drain valve body 8 is designed as a cylindrical or conical shape with a fluid outlet at the bottom. Locking cap 10 is designed as a cylindrical or hexagonal shape with internal threads or snap structures matching the side valve ports of the three-way valve ball. Handle 3 is designed in a shape that is easy for users to rotate or push, such as a cylindrical or rectangular shape.

[0039] (3) Assembly process: First, install O-ring one 5 at the bottom of valve stem 4, then insert the valve stem into the top valve port of three-way valve ball 6, and rotate or move the valve stem to ensure that O-ring one is in close contact with the three-way valve ball. Next, install sealing ring 7 at the top of drain valve body 8, and connect the drain valve body with the bottom valve port of the three-way valve ball. Then, install O-ring two 9 on the side valve port of the three-way valve ball, and tighten locking cap 10 on the side valve port of the three-way valve ball. Finally, fix handle 3 at the top of the valve stem, and fix decorative cover 1 at the top of the handle through cross screw 2.

[0040] (4) Debugging and testing: After assembly, the valve is debugged and tested. First, check whether each component is installed correctly and tightly, ensuring that there are no loose or damaged components. Then, perform a sealing test on the valve to ensure that there is no fluid leakage in the closed state. Finally, perform a flow control test on the valve to ensure that the size of the fluid flow can be accurately controlled by rotating the handle.

[0041] (5) Installation and use: Install the debugged valve on the fluid pipeline, and connect sensors and wireless communication modules as needed. When using, rotate the handle according to actual needs to control the flow direction and flow rate of the fluid. If remote monitoring and control of the valve is required, it can be operated through a mobile phone APP or computer terminal.
