Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner repair tools, and more specifically, to an air conditioner valve core quick replacement tool. Background Technology

[0002] In the field of air conditioning system maintenance, the valve core, as a core component for refrigerant flow control, requires regular replacement to ensure the long-term operation of the equipment. However, the current replacement process for air conditioning valve cores has significant drawbacks: First, traditional disassembly methods require the sequential removal of multiple related components such as the valve cover, sealing ring, and fastening bolts, making the operation cumbersome and taking an average of over 30 minutes, severely impacting maintenance efficiency; second, existing tools on the market (such as general-purpose pipe wrenches and adjustable wrenches) suffer from the following technical limitations:

[0003] 1) Insufficient compatibility between the tool end structure and the hexagonal groove of the valve core can easily lead to force deviation, causing the valve body to slip or the sealing surface to be damaged.

[0004] 2) The lack of optimized design for narrow installation spaces makes it difficult for maintenance personnel to perform effective clamping actions in areas with dense pipes;

[0005] 3) The functional modules are discrete, and different specifications of tools need to be changed repeatedly during the operation to meet the needs of multiple stages such as valve core disassembly and seal cleaning, which further increases the complexity of the operation.

[0006] Furthermore, with the trend of miniaturization in variable frequency air conditioning systems, valve core installation locations generally exhibit deep cavity and low visibility layout characteristics. Existing tools, lacking axial guide structures or visual aids, frequently cause misalignment by maintenance personnel, even leading to refrigerant leakage accidents. Therefore, there is an urgent need for a quick replacement tool for air conditioning valve cores that integrates rapid positioning, facilitates valve core clamping, and has axial guidance functions. Utility Model Content

[0007] The technical problem to be solved by this utility model is to achieve the convenience of quick positioning and clamping of valve cores, realize the axial guiding function, and avoid valve core misalignment. In order to overcome the above-mentioned defects of the prior art (or related technology), this utility model provides a quick replacement tool for air conditioning valve cores.

[0008] This utility model provides a quick replacement tool for an air conditioning valve core, including a tool body and a valve core rod. The tool body has an internal channel for the valve core rod to extend into. The tool body includes a quick connector, a first connector, a sealing balloon valve, and a second connector that are fixedly connected in sequence. The end of the quick connector facing away from the first connector has a threaded opening that matches the air conditioning valve core. The sealing balloon valve has a wrench for controlling the opening and closing of the sealing balloon valve. One end of the valve core rod has a valve core retainer for clamping the valve core located inside the air conditioning valve core. The other end of the valve core rod has a valve core rod knob for the user to hold and rotate the valve core rod to remove the valve core.

[0009] Compared with the prior art, the quick replacement tool for air conditioning valve cores disclosed in this application has the following advantages:

[0010] In this application, the valve core is fixed to the outer peripheral wall of the air conditioning valve core by rotating the threaded port inside the quick connector. Then, the sealing balloon valve is opened by controlling the wrench, and the valve core rod is inserted into the channel of the tool body to clamp the valve core inside the air conditioning valve core. The valve core is unscrewed by rotating the valve core rod knob. After the valve core is removed, the sealing balloon valve is closed by controlling the wrench. The whole process can achieve rapid positioning and clamping of the valve core, and the axial guidance can be achieved by the channel inside the tool body to avoid valve core misalignment.

[0011] In one possible implementation, a silicone pad is laid on the inner wall of the channel near the quick connector.

[0012] Compared with existing technologies, the above technical solution can buffer the valve core retainer on the valve stem by using a silicone pad, avoiding severe wear and extending the service life of the valve core retainer.

[0013] In one possible implementation, a sealing knob is sleeved on the outer wall of the valve core rod and is located close to the valve core rod knob, and the sealing knob is fixedly connected to the valve core rod.

[0014] Compared with the existing technology, after adopting the above technical solution, when the valve core rod is fully inserted into the channel, one end of the sealing knob abuts against the second connector to achieve sealing and prevent air leakage from the channel.

[0015] In one possible implementation, at least one oil seal ring is provided at the connection between the sealing knob and the valve stem.

[0016] In one possible implementation, the outer wall of the sealing knob is engraved with a checkered pattern.

[0017] Compared with existing technologies, the above technical solution can enhance the grip friction and prevent slippage.

[0018] In one possible implementation, the sealing knob and the valve stem knob have the same outer diameter.

[0019] In one possible implementation, a threaded hole is formed on the outer wall of the valve stem knob, and the threaded hole passes through the valve stem. The valve stem knob and the valve stem are fixed by a screw that engages with the threaded hole.

[0020] In one possible implementation, the outer wall of the valve stem knob is engraved with a checkered pattern.

[0021] Compared with existing technologies, the above technical solution can enhance the grip friction and prevent slippage. Attached Figure Description
