[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0031] The stop valve 100 according to an embodiment of the first aspect of the utility model is described below with reference to the accompanying drawings.

[0032] According to some embodiments of the present invention, the stop valve 100 is as follows: Figure 1 and Figure 2As shown, the stop valve 100 includes: a valve body 1, a valve bonnet 2 and a warning member 3, the valve body 1 includes a main body 12 and a filling portion 11, the filling portion 11 has a filling port 1121, the valve bonnet 2 is detachably arranged on the filling portion 11 to seal the filling port 1121, and the warning member 3 is installed on the filling portion 11 and is located on a side of the valve bonnet 2 close to the main body 12.

[0033] The stop valve 100 of the first embodiment of the utility model is used for temperature control equipment, such as air conditioners, etc. The following description is made by taking the stop valve 100 used for air conditioners as an example to facilitate the description of the utility model and the understanding of the utility model.

[0034] The stop valve 100 is provided with a charging portion 11, and refrigerant can be charged into the air conditioner through a charging port 1121 of the charging portion 11. The valve cap 2 is detachably provided on the charging portion 11. When the valve cap 2 is provided on the charging portion 11, the valve cap 2 seals the charging port 1121 to prevent the refrigerant from leaking from the charging port 1121; when the valve cap 2 is separated from the charging portion 11, the charging port 1121 is opened to facilitate charging of refrigerant into the air conditioner.

[0035] In the related art, new refrigerants do not deplete the ozone layer, have low global warming potential, and are much more environmentally friendly. For example, R454B refrigerant is a non-azeotropic environmentally friendly refrigerant that does not deplete the ozone layer and has low global warming potential, so it is widely used in air conditioners. However, R454B refrigerant is slightly flammable, and the process of filling R454B into the air conditioner through the filling port is dangerous. Improper operation may cause refrigerant leakage or even explosion.

[0036] In the embodiment of the utility model, the filling part 11 of the stop valve 100 is equipped with a warning piece 3, which can play a warning role, prevent non-operating personnel from touching it, help to quickly identify the filling part 11, reduce the occurrence of accidental touch, and thus reduce the probability of accidents. The stop valve 100 has multiple ends, and by installing the warning piece 3 on the filling part 11, it is also helpful for operators to quickly find the filling part 11 to improve the filling efficiency.

[0037] For example, the warning area 3a may include a warning pattern or text, and the warning area 3a may also be a portion with warning information. The warning element 3 may also serve as a reminder to remind the operator to strictly follow the regulations to improve the safety of the filling process; and may also remind the operator to perform targeted operations on the stop valve 100 with the warning element 3, thereby improving the filling efficiency.

[0038] In some countries and regions, there are clear regulatory requirements for the design and use of the filling part of the stop valve of the air conditioner. For example, the certification standard issued by UL (Underwriters Laboratories) has safety requirements for the design of the filling part of the stop valve for air conditioners using R454B refrigerant. The stop valve 100 of the embodiment of the utility model can meet the UL certification requirements by installing the warning member 3 on the filling part 11, so as to improve the safety of the use of the stop valve 100.

[0039] In some embodiments of the utility model, the warning member 3 is located on a side of the valve bonnet 2 close to the main body 12. When disassembling the valve bonnet 2, it is not necessary to remove the warning member 3 first, thereby avoiding interference with the disassembly and assembly of the valve bonnet 2 and the filling part 11, improving the disassembly and assembly efficiency of the valve bonnet 2, and thus improving the filling efficiency.

[0040] It is worth noting that there are many types of new refrigerants, for example, R454C refrigerant, R1270 refrigerant, R600a refrigerant, etc. For air conditioners using the above-mentioned flammable refrigerants, the stop valve 100 of the embodiment of the utility model can be used to improve safety of use.

[0041] According to the stop valve 100 of the embodiment of the utility model, by installing the warning piece 3 on the filling part 11, the warning piece 3 can play a warning role to prevent non-operating personnel from touching it, which helps to quickly identify the filling part 11 and reduce the occurrence of accidental touching, thereby reducing the probability of accidents.

[0042] In some embodiments of the present invention, Figure 3 As shown, the warning member 3 is configured to be longer than its width, and the length direction of the warning area 3 a of the warning member 3 is consistent with the length direction of the warning member 3 .

[0043] The warning member 3 uses the portion in the length direction for warning and reminder, thereby reducing the dimensions in other directions, such as reducing the dimensions in the width direction or the thickness direction, to save manufacturing costs, and reduce the space occupied in other directions, which is convenient for the installation of the warning member 3, and can also avoid interference with the valve cap 2, thereby improving the working reliability of the stop valve 100.

[0044] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, one end of the warning member 3 in the length direction is configured as a mounting portion 31 , and the mounting portion 31 is mounted on the filling portion 11 .

[0045] One end of the warning member 3 in the length direction is used for installation, which can improve the installation stability of the warning member 3 and reduce the shaking of the warning member 3 compared to installing it in the middle of the length direction of the warning member. In addition, by using one end of the warning member 3 in the length direction for installation, the warning member 3 only occupies the space on one side of the filling part 11, which can reduce the space occupied by the other end of the filling part 11, facilitate the installation of the warning member 3, and avoid interference with the valve cap 2.

[0046] In some embodiments of the present invention, Figure 2 As shown, the filling portion 11 includes a pipe section 111 for mounting the warning member 3 and a joint section 112 for mounting the valve cap 2 , and the joint section 112 is provided with a filling port 1121 .

[0047] like Figure 3 As shown, the mounting portion 31 is an open ring 310, and the opening 311 of the open ring 310 is smaller than the outer diameter of the pipe section 111, and the pipe section 111 is suitable for being inserted into the open ring 310 through the opening 311 of the open ring 310. The open ring 310 can produce elastic deformation, and after the open ring 310 is deformed, the size of the opening 311 of the open ring 310 can be increased to allow the pipe section 111 to enter the open ring 310. After the pipe section 111 is located in the open ring 310, the open ring 310 returns to its original state, the size of the opening 311 is smaller than the outer diameter of the pipe section 111, and the warning member 3 is limited in the filling portion 11, and the warning member 3 is installed in the filling portion 11.

[0048] By constructing the mounting portion 31 as an open ring 310, the warning member 3 has a simple structure and is easy to manufacture, which can reduce manufacturing costs and facilitate the installation of the warning member 3; and the installation and coordination of the warning member 3 and the filling portion 11 can be completed without additional design improvements to the pipe section 111, thus saving the cost of redesigning and mold making, and further reducing production costs.

[0049] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, a block 312 protrudes from the open ring 310, and a slot 1111 is provided on the pipe section 111. The block 312 extends into the slot 1111 and is plugged into the slot 1111. The block 312 cooperates with the slot 1111 to limit the relative axial displacement of the warning member 3 and the pipe section 111. It is worth noting that the above-mentioned axial direction is the axial direction of the pipe section 111. By setting the block 312 and the slot 1111, the axial movement of the warning member 3 relative to the pipe section 111 can be limited. The warning member 3 is stably installed on the pipe section 111, which can improve the axial shaking of the warning member 3 when it is impacted, and improve the working reliability of the warning member 3.

[0050] By setting the block 312 and the slot 1111 to cooperate with each other, the connection stability between the open ring 310 and the pipe section 111 can be improved, and the cooperation between the block 312 and the slot 1111 can be used as a basis for proper assembly. When the warning member 3 is installed on the pipe section 111, the block 312 extends into the slot 1111 to provide a sense of proper assembly, which can improve the assembly efficiency and the qualified rate of the assembly of the warning member 3.

[0051] In some embodiments of the utility model, the depth of the card slot 1111 is 0.5mm-1mm. If the depth of the card slot 1111 is too large, the thickness of the pipe section 111 will be reduced, and the working reliability of the filling part 11 will be reduced. If the depth of the card slot 1111 is too small, the matching stability of the card block 312 and the card slot 1111 will be reduced, which will reduce the installation stability of the warning member 3. Therefore, it is best to set the depth of the card slot 1111 to 0.5mm-1mm, which will improve the working stability of the filling part 11 and the installation stability of the warning member 3.

[0052] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the cross-sectional outer contour of the open ring 310 is an arc, that is, the cross-sectional shape of the open ring 310 is configured as a portion of a disk, and the clamping block 312 is arranged on the inner wall of the open ring 310 and extends along the radial direction of the open ring 310. Correspondingly, a clamping groove 1111 is provided on the outer wall of the pipe section 111, and the clamping groove 1111 extends along the radial direction of the pipe section 111, and the clamping block 312 cooperates with the clamping groove 1111 to limit the displacement of the warning member 3.

[0053] In other embodiments of the utility model, the mounting portion 31 is an open ring 310, a block 312 extending toward the inside of the open ring 310 is provided in the open ring 310, and a slot 1111 is provided on the pipe section 111. Only by the cooperation of the block 312 and the slot 1111, the warning member 3 can be limited in the filling portion 11, and the warning member 3 can be installed in the filling portion 11. By the cooperation of the block 312 and the slot 1111, the opening 311 of the open ring 310 does not need to be installed and cooperated with the pipe section 111, and the open ring 310 can be designed to have a larger opening 311, thereby saving manufacturing materials and manufacturing costs.

[0054] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, there are multiple slots 1111 and they are arranged at intervals along the circumference of the pipe section 111 . The number of the blocks 312 is the same as the number of the slots 1111 and they are arranged in a one-to-one correspondence to limit the relative circumferential displacement between the warning member 3 and the pipe section 111 .

[0055] By providing a plurality of clamping blocks 312 and clamping grooves 1111, the connection stability between the warning member 3 and the pipe section 111 can be further improved. Since the plurality of clamping grooves 1111 are arranged at intervals along the circumference of the pipe section 111, the clamping blocks 312 are also arranged at intervals along the circumference of the pipe section 111 and correspond to the clamping grooves 1111 one by one, so that the warning member 3 is stably installed on the pipe section 111, and the circumferential shaking of the warning member 3 when impacted can be reduced, thereby improving the working reliability of the warning member 3.

[0056] In some embodiments of the utility model, there are multiple slots 1111 and they are arranged at intervals along the circumference of the pipe section 111, and at least two slots 1111 are arranged opposite to each other in the radial direction of the pipe section 111, and the number of the blocks 312 is the same as the number of the slots 1111 and they are arranged in a one-to-one correspondence. By providing two slots 1111 arranged opposite to each other in the radial direction, the relative radial displacement between the warning member 3 and the pipe section 111 can be limited, and the shaking of the warning member 3 in the radial direction when impacted can be improved.

[0057] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, two slots 1111 are arranged on the pipe section 111, and the two slots 1111 are arranged at intervals along the circumference of the pipe section 111, and the two slots 1111 are arranged opposite to each other in the radial direction of the pipe section 111. Two blocks 312 protrude from the open ring 310, and the two blocks 312 are also arranged opposite to each other. The blocks 312 correspond to the slots 1111 one by one, and the blocks 312 extend into the slots 1111 and are plugged into the slots 1111. The warning member 3 is stably installed on the pipe section 111, which can limit the relative axial displacement, relative circumferential displacement and relative radial displacement between the warning member 3 and the pipe section 111, and can improve the shaking of the warning member 3 when it is impacted. The warning member 3 is installed on the filling part 11 in a relatively stable posture, which improves the working reliability of the warning member 3.

[0058] In some embodiments of the present invention, the warning member 3 is in the shape of a sheet with a thickness smaller than its width.

[0059] The warning piece 3 is constructed in a shape whose length is greater than its width, and is also constructed in a sheet shape whose thickness is less than its width. The warning piece 3 uses the lengthwise portion for warning and reminder, thereby reducing the dimensions in the widthwise and thicknesswise directions to save manufacturing costs.

[0060] In some embodiments of the present invention, the filling part 11 includes a pipe section 111 for installing the warning member 3. When the warning member 3 is installed in the filling part 11, the thickness direction of the warning member 3 is installed on the pipe section 111 along the axial direction of the pipe section 111, so the warning member 3 occupies the axial space of the pipe section 111. By designing the warning member 3 as a sheet with a thickness less than the width, the space occupied in the axial direction can also be reduced, avoiding interference with the valve cap 2, and improving the working reliability of the stop valve 100.

[0061] In some embodiments of the present invention, the warning member 3 has a thickness of 0.5-3 mm.

[0062] The thickness of the warning piece 3 is smaller than the width of the warning piece 3 and much smaller than the length of the warning piece 3, thereby saving manufacturing costs, reducing the space occupied, facilitating the installation of the warning piece 3, avoiding interference with the valve cap 2, and improving the working reliability of the stop valve 100. However, when the thickness of the warning piece 3 is too low, the structural strength of the warning piece 3 will be reduced, and the warning piece 3 will be easily damaged when impacted, reducing the service life of the warning piece 3, and reducing the working reliability of the warning piece 3. Designing the thickness of the warning piece 3 to be 0.5mm-3mm can not only effectively reduce the manufacturing cost of the warning piece 3 and reduce the space occupied, but also improve the structural strength of the warning piece 3, and the working reliability of the warning piece 3 is strong.

[0063] Optionally, the thickness of the warning member 3 may be 0.5 mm, 1 mm, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, 3 mm, etc.

[0064] In some embodiments of the utility model, the warning member 3 has a warning area 3a, and the length of the warning area 3a is greater than the maximum size of the valve cap 2. The warning member 3 is provided to warn and remind, thereby improving the safety of use and reducing the probability of accidents. In addition, by adding the warning member 3, the original structure of the stop valve 100 may not be changed, or the structural change of the stop valve 100 may be minor, so that no additional design and mold opening are required, thereby reducing the production cost.

[0065] It is worth noting that the maximum size of the valve bonnet 2 refers to the maximum size of the valve bonnet 2 in any direction, and any direction of the valve bonnet 2 includes the axial direction of the valve bonnet 2, the radial direction of the valve bonnet 2, the length direction of the valve bonnet 2, or the diagonal direction of the projection of the valve bonnet 2. If the maximum size of the valve bonnet 2 is not sufficient to serve as a warning, a warning member 3 is provided for warning and reminder. The warning member 3 has a warning area 3a, and the length of the warning area 3a is greater than the size of the valve bonnet 2 in any direction. The warning area 3a of the warning member 3 serves as a warning and reminder, thereby improving the safety of the stop valve 100.

[0066] In some embodiments of the utility model, the warning member 3 has a warning area 3a, and the length of the warning area 3a is greater than the length of the valve cap 2 in the warning area 3a. The length of the warning area 3a is greater than the length of the valve cap 2 in the warning area 3a. By providing the warning member 3 for warning and reminder, the safety of use is improved and the probability of accidents is reduced.

[0067] If the size of the valve cap 2 in a certain direction is not enough to serve as a warning, a warning piece 3 can be provided to provide a warning and reminder. For example, when the stop valve 100 is in working state, a certain part of the stop valve 100 is the part most easily observed by the user, so the extension direction of the easily observed part of the stop valve 100 is defined as the warning direction. If the size of the valve cap 2 in the warning direction is not enough to serve as a warning, a warning piece 3 can be provided, and the length of the warning area 3a on the warning piece 3 in the warning direction is greater than the size of the valve cap 2 in the warning direction, and the warning piece 3 can serve as a warning and reminder.

[0068] In some embodiments of the utility model, the warning member 3 has a warning area 3a, the length of the warning area 3a is greater than or equal to the specified warning size, the warning area 3a is more conspicuous, the observer can quickly obtain the warning information, the warning and reminder function of the warning member 3 can be enhanced, the safety of the stop valve 100 is improved, and the probability of accidents is reduced.

[0069] In addition, in some countries and regions, there are regulatory requirements for the design and use of the filling part of the stop valve of the air conditioner. By limiting the length of the warning area 3a to be greater than or equal to the specified warning size, the design requirements can be met.

[0070] For example, the certification standard issued by UL (Underwriters Laboratories) requires that the filling part of the stop valve be provided with a warning mark for air conditioners using R454B refrigerant, and the warning mark must meet the specified size. In some embodiments of the stop valve 100 of the utility model, the maximum size of the valve cap 2 does not meet the limit size. In this case, the warning member 3 is provided, and the warning member 3 has a warning area 3a, the length of which is greater than the maximum size of the valve cap 2, and the length of the warning area 3a is greater than or equal to the specified size, so as to meet the UL certification.

[0071] It is worth noting that the above-mentioned limited size is a type of prescribed warning size, but the limited size issued by UL certification cannot be used as the only prescribed warning size requirement. The length of the warning area 3a of the embodiment of the utility model can be selected according to actual needs, so as to meet different prescribed warning size requirements.

[0072] In some embodiments of the present invention, the warning size is set to 26 mm, and the length of the warning area 3a is greater than or equal to 26 mm. The warning area 3a is more conspicuous, and the observer can quickly obtain the warning information, which can enhance the warning and reminder function of the warning member 3, improve the safety of the stop valve 100, and reduce the probability of accidents.

[0073] The certification standards issued by UL require that for air conditioners using R454B refrigerant, a warning mark be provided on the filling portion of the stop valve, and the warning mark must be at least 1 inch (25.4 mm) long. In some embodiments of the utility model, the length of the warning area 3a is greater than or equal to 26 mm, which can meet the certification standards issued by UL.

[0074] In some embodiments of the present invention, the length direction of the warning area 3a is perpendicular to the axial direction of the filling port 1121. When refrigerant is charged through the filling port 1121 of the charging portion 11, the operation is performed along the axial direction of the filling port 1121, and the operator can more easily observe the warning area 3a arranged perpendicular to the axial direction of the filling port 1121, and the operator can quickly obtain warning information, which can enhance the warning and reminder function of the warning member 3 and reduce the probability of accidents.

[0075] With the filling port 1121 as a reference, the length direction of the warning area 3a is the radial direction of the filling port 1121, and the warning area 3a is more conspicuous and easier to observe.

[0076] In some embodiments of the present invention, the warning member 3 is configured to be longer than its width, and the length direction of the warning area 3 a is consistent with the length direction of the warning member 3 .

[0077] The length of the warning piece 3 is utilized to serve as a warning and reminder, thereby reducing the dimensions in other directions, such as reducing the dimensions in the width direction or the thickness direction, to save manufacturing costs, and reduce the space occupied in other directions, thereby facilitating the installation of the warning piece 3.

[0078] In some embodiments of the present invention, Figure 3 As shown, the warning member 3 includes a connected mounting portion 31 and a warning portion 32 in the length direction, the mounting portion 31 is mounted on the filling portion 11, and the warning portion 32 extends radially along the filling port 1121, and the mounting portion 31 and the warning portion 32 are jointly constructed as a warning area 3a, and the dimensions of the mounting portion 31 and the warning portion 32 in the length direction of the warning member 3 are 26 mm to serve as a warning and reminder.

[0079] In some embodiments of the present invention, the warning area 3a of the warning member 3 is a prescribed warning color. The warning area 3a is more conspicuous, and the observer can quickly obtain the warning information, which can enhance the warning and reminder function of the warning member 3, improve the safety of the stop valve 100, and reduce the probability of accidents.

[0080] In addition, by designing the warning area 3a to be a specified warning color, the design requirements for stop valves in some countries and regions can be met. For example, the certification standard issued by UL (Underwriters Laboratories) requires that a warning mark with a warning color be set on the filling part of the stop valve for air conditioners using R454B refrigerant. In some embodiments of the utility model, by setting a warning member 3, the warning area 3a of the warning member 3 is a specified warning color, thereby meeting UL certification.

[0081] In some embodiments of the present invention, the warning color is set to red. The warning area 3a of the warning member 3 is red. The warning area 3a is more conspicuous, which can enhance the warning and reminder function of the warning member 3 and improve the safety of the stop valve 100.
