Description

Technical Field

[0001] This utility model relates to the field of pipeline valve device technology, and in particular to a three-way valve that is easy to disassemble and assemble. Background Technology

[0002] In modern buildings, especially residential and industrial buildings, the use of dual heat sources (such as solar energy and gas boilers, heat pumps and boilers) to supply domestic hot water or process hot liquids has become a common and energy-efficient configuration. In industrial production, supply pipelines for two different liquids (such as coolant and raw material liquid) often coexist. Such multi-source supply systems typically use three-way valves at pipe connections to switch, distribute, or mix fluid flows.

[0003] The installation of these three-way valves, especially in domestic hot water pipe systems, is often done by connecting them to the wall-mounted pipes for aesthetic and space-saving purposes. Most existing three-way valves are one-piece cast or forged structures, with a permanent rigid connection between the valve body and the external pipe, making the valve itself an inseparable unit. When the three-way valve or the connecting pipe needs repair or replacement, the entire three-way valve needs to be replaced. Since it is embedded in the wall, it is necessary to break open part of the wall for destructive construction, resulting in a large amount of work, a lot of construction waste, and additional material, labor, and restoration costs. Furthermore, it is difficult to maintain the original appearance of the wall afterward, seriously damaging the aesthetics and overall consistency of the decoration.

[0004] In existing renovations or construction, multiple replaceable shut-off valves are often installed, but the conversion is troublesome, and the large number of valves can easily cause confusion, resulting in inconvenience in use.

[0005] A split-type three-way valve, publication number CN207848490U, published on September 11, 2018, is disclosed in the Chinese Patent Database. The device includes a three-way valve body and a valve core. The three-way valve body is hollow and has three ports, each connected to a connecting pipe. A disassembly pipe and a control pipe are integrally formed on the outer periphery of the three-way valve body. Both the disassembly pipe and the port end face have an annular groove a, and the disassembly pipe end is connected to a fixed cap. A valve seat is inserted into both the ports and the disassembly pipe. The valve seat includes a base and a locking part. The outer periphery of the base fits against the inside of the three-way valve body, and the end of the base near the connecting pipe has an annular groove b. The end of the locking part away from the base has a circular groove containing a rubber ring. This split-type three-way valve, with its connecting and disassembly pipes, allows for easy replacement of the valve seat or rubber ring by simply removing the corresponding connecting pipe or fixed cap, simplifying maintenance. The shortcomings of this device are as follows: the disassembly pipe and the control pipe are set opposite each other, and both are perpendicular to the port. If it is installed in the wall, the connecting pipes are fixed with no room for movement, which can be understood as rigid. However, disassembly and assembly require room for movement. When the valve body is connected to the pipes buried in the wall, maintenance and replacement still require breaking and chiseling the wall for destructive construction, which is a large amount of work and costly. Therefore, this device is not suitable for connecting pipes buried in the wall. In addition, the valve body occupies a lot of space when assembled, and requires more wall excavation depth when buried in the wall, which is even more costly. Utility Model Content

[0006] The purpose of this utility model is to provide a three-way valve that is easy to assemble and disassemble. The valve mounting base is connected to the pipe buried in the wall, and the valve body is detachably connected to the valve mounting base. When repairing or replacing the three-way valve components, it is not necessary to disassemble the connection interface between the three-way valve and the pipe buried in the wall. The operation is convenient and will not damage the wall. The overall structure of the valve is compact and thin, which helps to reduce the depth of the pipe buried in the wall.

[0007] The purpose of this utility model is achieved as follows: A three-way valve that is easy to assemble and disassemble includes a valve mounting seat, a valve body, and a drive mechanism. The valve mounting seat has an opening in the middle for mounting the valve body. The opening has three inner mounting bevels, and the valve mounting seat has three connecting passages on its outer side. The outer ports of the three connecting passages are connected to the wall-embedded pipes via connectors. The inner ports of the three connecting passages are respectively located on the three inner mounting bevels. The valve body has outer mounting bevels corresponding to the three inner mounting bevels. The valve body has three connecting passages separated by a valve core, and the three connecting passages extend from the inner mounting bevels into the valve body. The valve body is fitted into the opening, and the valve mounting seat and the valve body are connected by fastening screws, so that the outer mounting bevels and inner mounting bevels are pressed together. The three connecting passages in the valve body are sealed to the inner ports, and the pressing force is converted into tension on three sides to achieve the effect of pressing and sealing the inner ports. The drive mechanism is mounted on the valve body and is drivenly connected to the valve core. The opening and closing of the three connecting passages is achieved by controlling the rotation of the valve core.

[0008] Furthermore, a sealing ring is provided between the outer mounting bevel and the inner mounting bevel, and the sealing ring is embedded in the sealing groove, which is located on the outer mounting bevel or the inner mounting bevel around the inner port.

[0009] Furthermore, the valve core is a ball valve core, and the ball valve core has three channels corresponding to the three connection passages in the valve body. The driving mechanism includes a drive motor, and the output shaft end of the drive motor is connected to the valve stem. The valve stem is connected to the ball valve core. By rotating the valve stem, the ball valve core is driven to rotate, so that the three channels are connected or disconnected from the three connection passages in the valve body, thereby realizing the on / off and switching of the three-way valve.

[0010] Furthermore, the drive motor is mounted against the side of the valve body where no connecting passage is provided, and the output end of the drive motor is connected to a drive gear. The drive gear meshes with a driven gear, and the center of the driven gear is fixed to the valve stem.

[0011] Furthermore, the opening is located on the front of the valve mounting seat, the inner bottom of the opening is a connecting plate, the three inner mounting slopes form the three sides of the opening respectively, the fourth side of the opening is a notch, and the drive motor is located on one side of the notch.

[0012] Furthermore, the valve body and the connecting plate are respectively provided with arc-shaped slots, and the drive motor is side-mounted within the arc-shaped slots.

[0013] Furthermore, the valve mounting base and valve body are integrally housed within a concealed box, which is pre-embedded in the wall and has a removable cover plate on its surface; a square hole can also be directly opened in the wall to accommodate the valve mounting base and valve body.

[0014] Furthermore, the drive motor is located on the outer extension line of the valve stem, and the output end of the drive motor is directly connected to the valve stem.

[0015] Furthermore, the drive mechanism can be a handle.

[0016] Furthermore, the valve mounting base and valve body are integrally housed within the wall, while the drive mechanism protrudes outside the wall.

[0017] In operation, the valve mounting seat of this utility model is installed in a concealed box or a square hole in the wall. The three connecting passages of the valve mounting seat are connected to the buried pipe through connectors. The valve body is fitted into the valve mounting seat through the opening and fixed by fastening screws, so that the outer mounting bevel of the valve body is pressed against the inner mounting bevel of the valve mounting seat. The three connecting passages on the valve body are sealed to the inner ports of the connecting passages on the valve mounting seat. The valve core inside the valve body is driven by a drive motor, so that the channel on the valve core is connected or disconnected from the three connecting passages on the valve body, realizing the on / off and switching of the three-way valve. After the three-way valve is installed, a removable cover plate is set on the wall surface. When it is necessary to repair or replace the internal seals of the valve body or the valve core and other components, the cover plate can be opened directly and the valve body can be removed from the valve mounting seat without chiseling the wall, thus maintaining the aesthetics and overall consistency of the wall.

[0018] Compared with the prior art, the advantages of this utility model are as follows: First, the outer mounting bevel of the valve body and the inner mounting bevel of the valve mounting seat are tightly fitted together, and an effective seal is formed at the connection passage interface on the bevel, resulting in excellent pipeline sealing and preventing leakage when liquid passes through the valve body; Second, the valve body is designed to be replaceable, making construction convenient. Water flow testing can be carried out immediately after valve body installation, and any leakage can be dealt with promptly without damaging the wall surface; when maintenance or replacement is required, there is no need to damage the original decoration, greatly reducing costs and shortening the repair period; Third, the three-way valve is installed inside the wall through a concealed box, and the pipeline connection and valve body are not affected by external collisions or moisture interference, resulting in excellent long-term reliability.
