Description

Technical Field

[0001] The present application relates to the technical field of three-way valve maintenance, and more specifically, to a three-way valve that is easy to maintain. Background Art

[0002] As a key device in the building heating, ventilation and air conditioning system, the performance and maintenance of the three-way valve are crucial to the efficiency and reliability of the entire system. However, traditional three-way valves have some shortcomings, especially in environments with high-intensity use and poor water quality. These problems are particularly prominent.

[0003] Most traditional three-way valves adopt a fixed structure design, which makes the disassembly and maintenance process cumbersome and time-consuming when cleaning scale or foreign matter. When facing poor water quality, especially water with high calcium and magnesium content, traditional three-way valves are prone to scale formation in the valve body, affecting the efficiency and life of the valve.

[0004] To this end, the present application proposes a three-way valve that is easy to maintain to solve the above-mentioned problems. Utility Model Content

[0005] In order to solve the above problems, the present application provides a three-way valve that is easy to maintain.

[0008] An upper shell, the bottom of which is detachably connected to a lower shell, a cavity is formed between the upper shell and the lower shell, and the cavity is used to install a valve body assembly;

[0009] A quick-repair opening is provided on the upper shell, and a plurality of positioning columns are arranged around the quick-repair opening on the upper shell. The positioning columns include side columns arranged on both sides of the quick-repair opening and a middle column arranged on the center line of the quick-repair opening. The side columns are provided with limited holes, and the middle column is provided with a card slot;

[0010] A quick-release shell, wherein a positioning hole matching the positioning column is provided at the edge of the quick-release shell, and the quick-release shell is detachably connected to the upper shell body through the positioning column; the height of the limiting hole and the card slot is higher than the depth of the positioning hole; the quick-release shell covers the quick repair port;

[0011] A quick-release fork passes through the positioning hole of each side column and is engaged with the slot.

[0012] Furthermore, the quick-release fork is an integrally formed structure and is made of metal.

[0013] Through the above technical solution, the stability and durability of the structure are enhanced, and the firmness of the connection between the quick-release shell and the upper shell body is ensured.

[0014] Furthermore, the connection between the quick repair port and the upper shell is of a sunken design.

[0015] Through the above technical solution, additional sealing performance is provided to prevent the penetration of water and impurities, thereby improving the protection level of the three-way valve body.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] (1) The maintenance of the three-way valve becomes faster and easier, greatly reducing maintenance time and cost, while improving the operating efficiency and life of the three-way valve body; effectively solving the problem of difficult maintenance of the traditional three-way valve body in high-intensity use and poor water quality environments.

[0025] Example:

[0026] The following is combined with Figure 1 -3 Provide further details of this application.

[0027] The embodiment of the present application discloses a three-way valve that is easy to maintain, comprising:

[0028] An upper shell 1, the bottom of which is detachably connected to a lower shell 2, a cavity is formed between the upper shell 1 and the lower shell 2, and the cavity is used to install the valve body assembly;

[0029] A quick repair opening 3 is provided on the upper shell 1. A plurality of positioning columns are arranged around the quick repair opening 3. The positioning columns include side columns 4 arranged on both sides of the quick repair opening 3 and a middle column 5 arranged on the center line of the quick repair opening 3. The side columns 4 are provided with limited holes 6, and the middle column 5 is provided with a card slot 7.

[0030] A quick-release shell 8, a positioning hole 9 matching the positioning column is provided at the edge of the quick-release shell 8, and the quick-release shell 8 is detachably connected to the upper shell 1 through the positioning column; the height of the limiting hole 6 and the card slot 7 is higher than the depth of the positioning hole 9; the quick-release shell 8 covers the quick repair port 3;

[0031] The quick release fork 10 passes through the positioning hole 9 of each side column 4 and engages with the slot 7 .

[0032] See also Figure 1 , Figure 2 and Figure 3 The quick release fork 10 is an integrally formed structure and is made of metal; the stability and durability of the structure are enhanced, and the firmness of the connection between the quick release shell 8 and the upper shell 1 is ensured.

[0033] See also Figure 1 , Figure 2 and Figure 3 The connection between the quick repair port 3 and the upper shell 1 is a sunken design, which provides additional sealing performance, prevents the infiltration of water and impurities, and improves the protection level of the three-way valve body.

[0034] The implementation principle of a three-way valve that is easy to maintain in the embodiment of the present application is:

[0035] When the three-way valve needs to be maintained or cleaned, the quick release fork 10 is pulled out in the opposite direction of the slot 7 to disengage the quick release fork 10 from the limiting hole 6, so that the quick release shell 8 is not restricted by the quick release fork 10. Through the cooperation of the quick release fork 10 and the positioning column, the quick release shell 8 is easily removed to expose the quick repair port 3.

[0036] After the quick release fork 10 is removed, the quick release shell 8 is lifted upwards, and the quick repair port 3 is exposed, so that the three-way valve body components located in the cavity formed by the upper shell 1 and the lower shell 2 can be repaired, and the valve body assembly can be inspected, cleaned or replaced as necessary.

[0037] After the maintenance is completed, the quick-release shell 8 is repositioned on the upper shell 1, and the quick-release fork 10 is engaged with the positioning column to ensure the stable connection of the quick-release shell 8; the entire maintenance process is completed.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
