By setting an anti-detachment protection part, it solves the problem that existing two-position three-way valves are not easy to prevent the protective cap from falling off during use. The protective cap may reverse and fall off due to vibration during transportation or operation, making it difficult to ensure that the protective cap can always seal the passage interface, thus leading to the entry of contaminants or leakage of media, affecting the stability and reliability of protection.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a two-position three-way valve, comprising: a two-position three-way valve, and further comprising: a plurality of anti-detachment protection parts, each disposed on the side wall of the two-position three-way valve; a plurality of disassembly parts, each mounted on the two-position three-way valve; the anti-detachment protection parts comprising an anti-detachment component mounted on the two-position three-way valve; and a protection component mounted on the two-position three-way valve; the anti-detachment component comprising two locking blocks disposed on the two-position three-way valve, with a fixing block disposed between the two locking blocks, and spring telescopic rods fixedly connected to the top and bottom of the fixing block, with the sides of the two spring telescopic rods away from the fixing block respectively fixedly connected to the two locking blocks; and a support member disposed on the two-position three-way valve; wherein, both the anti-detachment protection parts and the disassembly parts have five anti-detachment protection parts, and the anti-detachment component, through the cooperation of locking blocks, spring telescopic rods, etc., forms a limit on the rectangular block of the protective cap, preventing the protective cap from accidentally falling off and ensuring the stability of the protection function.

[0006] Furthermore, the protection component includes a threaded tube fixedly connected to the outer wall of the two-position three-way valve. A protective cap is threaded onto the outer wall of the threaded tube. An annular groove is formed on the outer wall of the protective cap, and a snap-fit ​​component is provided on the annular groove. The protective cap has anti-slip texture. The protection component is connected to the protective cap by the threaded tube. The combination of the anti-slip texture and the annular groove design achieves closed protection of the passage interface, while facilitating installation and fixation.

[0007] Furthermore, the disassembly unit includes a hinge assembly mounted on the two-position three-way valve; and a transmission assembly mounted on the two-position three-way valve. The hinge assembly includes hinge blocks one, which are respectively fixedly connected to the side of the two locking blocks away from the annular groove.

[0011] This utility model has the following beneficial effects: This application incorporates an anti-detachment protection unit, comprising an anti-detachment component and a protection component. The anti-detachment component utilizes two locking blocks, a fixing block, and a spring telescopic rod in cooperation. The extension and retraction of the spring telescopic rod controls the opening and closing of the locking blocks, thereby limiting the rectangular block on the protective cap. The threaded tube in the protection component cooperates with the protective cap to achieve a sealed protection of the passage interface. Its significance lies in ensuring that the protective cap is stably installed on the valve, effectively preventing the protective cap from reversing and falling off, ensuring the stability and reliability of the protection, and ensuring that the protective cap can always seal the passage interface during transportation, storage, or equipment operation, preventing contaminants from entering or media from leaking.

[0012] The disassembly section, consisting of a hinge assembly and a transmission assembly, connects the hinge block and hinge rod of the hinge assembly to the locking block of the anti-detachment protection section. The sliding rod and handle of the transmission assembly transmit the operating force. When the protective cap needs to be removed, pushing the sliding rod causes the locking blocks to move away from each other via the hinge rod, releasing the restriction on the rectangular block on the protective cap. This allows for easier disassembly and installation of the protective cap during maintenance, repair of the two-position three-way valve, or connection and replacement of pipelines, thereby improving the efficiency of protective cap disassembly and ensuring smooth operation.
