Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration, and particularly relates to a stop valve. Background Art

[0002] The stop valve plays a role in cutting off and connecting the medium in the pipeline where it is located. Especially in a refrigeration system, the stop valve is installed on the outdoor unit. The stop valve includes a charging nozzle, a valve core, a joint and a copper pipe; the copper pipe side is connected to the inside of the outdoor unit, the joint side is connected to the copper pipe of the indoor unit, the charging nozzle is arranged corresponding to the other side of the joint, and the operating part of the valve core is located at the top of the valve body. When the valve core is closed, the working areas for refrigerant charging and evacuation are on the joint side. In some cases, the air conditioner outdoor unit needs to be installed in a narrow space. With the stop valve of the above structure, either the operating part position of the valve core or the charging nozzle will always be located inside the narrow space, which makes it inconvenient to operate when charging the refrigerant or opening and closing the valve core. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a stop valve.

[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0005] A stop valve includes a valve body, on which there are a valve core opening, a valve nozzle opening, a connection pipe opening and an outdoor unit interface. The valve core opening and the outdoor unit interface are oppositely arranged at the respective ends of the valve body, the valve nozzle opening and the valve core opening are on the same side in the length direction of the valve body, the connection pipe opening is arranged on the end face at one end in the height direction of the valve body, and the connection pipe opening and the valve nozzle opening are on the same side of the valve core opening.

[0006] With such a setting, the valve core opening and the outdoor unit interface are arranged on the upper and lower sides at one end of the valve body, the connection pipe opening is arranged on the end face at the other end of the valve body, the valve nozzle opening is arranged on the side of the valve core opening close to the connection pipe opening and is arranged parallel to the valve core opening. When the stop valve with this structure is installed in a narrow space, the valve body extends outwards from the narrow space, which is convenient for refrigerant charging.

[0007] Further, the valve body is a cuboid.

[0008] With such a setting, on the one hand, the cuboid-shaped valve body has enough space to arrange the valve core opening, the valve nozzle opening and the connection pipe opening with interval dislocation, and on the other hand, it can make the refrigerant charging side extend out of the narrow space.

[0009] Further, on one side in the length direction of the valve body, there are a first protrusion and a second protrusion arranged at intervals, and the valve core opening and the valve nozzle opening are respectively arranged on the first protrusion and the second protrusion. With such a setting, the materials required for manufacturing the valve body are reduced.

[0010] Further, the stop valve further includes a flange plate. On the opposite side of the side where the first protrusion is located, there is a third protrusion opposite to the first protrusion. The flange plate and the valve body are of a split structure. Along the height direction of the valve body, the flange plate is placed outside the third protrusion, and the copper pipe connecting pipe penetrates through the flange plate.

[0011] With such a setting, the flange plate can be manufactured independently of the valve body, and the flange plate can be made of a material with a lower price compared to the valve body, reducing the overall manufacturing cost of the stop valve, and further reducing the production cost of the air conditioning equipment using this stop valve.

[0012] Further, on the lower end surface of the third protrusion, there is a fourth protrusion protruding outward from this end surface. The outdoor unit interface extends away from the valve body from the fourth protrusion. A through hole adapted to the fourth protrusion is provided on the flange plate, and the flange plate is clamped on the fourth protrusion. The height of the fourth protrusion is the same as the thickness of the flange plate, and the flange plate abuts against the lower end surface of the third protrusion.

[0013] Further, the shapes of the first protrusion, the second protrusion, the third protrusion, and the fourth protrusion are all rectangular structures, and the front and rear side surfaces of the first protrusion, the second protrusion, the third protrusion, and the fourth protrusion are all located in the same vertical plane as the front and rear side surfaces of the valve body.

[0014] Further, on the end surface adjacent to the end surface where the connection pipe orifice is located, there is an extension block extending away from the valve body. The lower end surface of the extension block is in the same horizontal plane as the lower end surface of the third protrusion, and the outer side surface of the extension block on the side away from the valve body is in the same vertical plane as the outer side surface of the flange plate on the side away from the valve body.

[0015] With such a setting, by providing the extension block, the contact area between the valve body and the flange plate is increased, further increasing the fitting firmness between the flange plate and the valve body.

[0016] Further, the length of the extension block in the width direction of the valve body is the same as or greater than the width of the valve body. With such a setting, by expanding the bottom area of the extension block, the contact area between the valve body and the flange plate is expanded, increasing the fitting firmness between the flange plate and the valve body.

[0017] Further, strip-shaped arc notches are provided at the joints of the fourth protrusion and the third protrusion in the width direction of the valve body, and the top corners of the through hole on the flange plate are located in the strip-shaped arc notches.

[0018] With such a setting, placing the top corner line of the through hole of the flange plate in the strip-shaped arc notch further increases the fitting firmness between the flange plate and the valve body.

[0019] Further, chamfers are provided at the four corners in the through hole of the flange plate, and the four vertical edges of the fourth protrusion are located in the chamfers.

[0020] With such a setting, the four vertical edges and corners of the fourth protrusion being located within the chamfer further increases the firmness of the fit between the flange plate and the valve body.

[0021] For the novel globe valve of the present utility model, the filling nozzle structure is arranged on one side valve pipe and is in a parallel state with the valve core structure, which is more convenient to operate when installed on the air conditioner mounting plate.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0031] Please refer to Figures 1 to 5 , the present invention provides a globe valve, which is used for connection, opening or closing of a pipeline system. In this embodiment, the globe valve is used for connection or closing of the outdoor unit and the refrigerant charging pipeline in a refrigeration system. Of course, in other embodiments, the globe valve can also be used in other pipeline systems.

[0032] Specifically, a novel globe valve includes a valve body 1, on which a valve core port 11, a valve nozzle port 12, a connection pipe port 13 and an outdoor unit interface 14 are provided. The valve core port 11 and the outdoor unit interface 14 are oppositely arranged at one end of the valve body 1. The valve nozzle port 12 and the valve core port 11 are on the same side of the valve body 1 in the length direction. The connection pipe port 13 is arranged on one end face of the valve body 1 in the height direction, and the connection pipe port 13 and the valve nozzle port 12 are on the same side of the valve core port 11.

[0033] It can be understood that the valve core port 11 and the outdoor unit interface 14 are arranged on the upper and lower sides at one end of the valve body 1, the connection pipe port 13 is arranged on the other end face of the valve body 1, the valve nozzle port 12 is arranged on the side of the valve core port 11 close to the connection pipe port 13 and is arranged parallel to the valve core port 11; under normal circumstances, the air conditioner outdoor unit interface 14 is fixedly connected to the outdoor unit and is not affected during the installation operation; when the globe valve with this structure is installed in a narrow space with the valve core port 11 and the valve nozzle port 12 on the same side, the valve body 1 extends outwards from the narrow space, which is convenient for refrigerant charging and opening and closing the valve core.

[0034] In some embodiments, the valve body 1 is a long strip structure, such as a cuboid, a cylinder, etc. The length of the valve body 1 is such that there is enough space in the length direction to set the valve core port 11, the valve nozzle port 12 and the connection pipe port 13 at intervals and in a staggered manner. In this embodiment, the valve body 1 is a cuboid.

[0035] Conventional valve nozzles and valve cores are standard parts and are of fixed length. Directly installing them on the valve body 1 of the present application will affect the overall height of the valve body 1. Therefore, in order to reduce the materials required for production, raised portions are separately provided at the positions of the valve nozzle and the valve core. Specifically, in some embodiments, a first raised portion 15 and a second raised portion 16 are provided at intervals on one side surface of the valve body 1 in the length direction, and the valve core port 11 and the valve nozzle port 12 are respectively arranged on the first raised portion 15 and the second raised portion 16.

[0036] The globe valve further includes a flange plate 2. A third protrusion 17 opposite to the first protrusion 15 is provided on the side opposite to the side where the first protrusion 15 is located, and the outdoor unit is connected to the third protrusion 17.

[0037] In one embodiment, the flange plate 2 and the valve body 1 are of a split structure. The flange plate 2 is placed outside the third protrusion 17, and the copper pipe connecting pipe 6 passes through the flange plate 2. To facilitate the connection between the flange plate 2 and the valve body 1, a fourth protrusion 18 protruding outward from this end face is provided on the lower end face of the third protrusion 17. The outdoor unit interface 146 extends away from the valve body 1 from the fourth protrusion 18. A through hole 21 adapted to the fourth protrusion 18 is provided on the flange plate 2, and the flange plate 2 is clamped on the fourth protrusion 18. Regarding the height of the fourth protrusion 18, if the height of the fourth protrusion 18 is less than the thickness of the flange plate 2, the connection between the two will be insecure. If the height of the fourth protrusion 18 is greater than the thickness of the flange plate 2, it will affect the stability of the connection between the globe valve and the air conditioner outdoor unit. Therefore, in this embodiment, the height of the fourth protrusion 18 is the same as the thickness of the flange plate 2.

[0038] In one embodiment, the shapes of the first protrusion 15, the second protrusion 16, the third protrusion 17, and the fourth protrusion 18 are rectangular structures. In other embodiments, the shapes of the first protrusion 15, the second protrusion 16, the third protrusion 17, and the fourth protrusion 18 can be other shapes, such as frustum shapes, etc.

[0039] In one embodiment, the front and rear side surfaces of the first protrusion 15, the second protrusion 16, the third protrusion 17, and the fourth protrusion 18 are all in the same vertical plane as the front and rear side surfaces of the valve body 1. It can be understood that such a setting can make the overall structural layout of the valve body 1 more reasonable.

[0040] In one embodiment, an extension block 19 extending away from the valve body 1 is provided on the end face opposite to the end face where the connection pipe orifice 13 is located. The lower end face of the extension block 19 is in the same horizontal plane as the lower end face of the third protrusion 17, and the outer side surface of the extension block 19 on the side away from the valve body 1 is in the same vertical plane as the outer side surface of the flange plate 2 on the side away from the valve body 1. It can be understood that by providing the extension block 19, the contact area between the valve body 1 and the flange plate 2 is increased to further increase the fitting firmness between the flange plate 2 and the valve body 1.

[0041] Furthermore, the length of the extension block 19 in the width direction of the valve body 1 is the same as or greater than the width of the valve body 1.

[0042] In one embodiment, strip-shaped arc notches 171 centered at the points on the intersection line of the third protrusion 17 and the fourth protrusion 18 are provided at the joints of the fourth protrusion 18 and the third protrusion 17 in the width direction of the valve body 1, and the top corners of the through holes 21 on the flange plate 2 are located within the strip-shaped arc notches 17. It can be understood that placing the top corner line of the through hole 21 of the flange plate 2 within the strip-shaped arc notch 17 further increases the fitting firmness between the flange plate 2 and the valve body 1.

[0043] In one embodiment, chamfers 23 with semi-circular arc-shaped contour surfaces recessed along the length of the flange plate are provided at the four corners within the through hole 21 of the flange plate 2, and the four vertical edges of the fourth protrusion 18 are located within the chamfers 23. It can be understood that placing the four vertical edges of the fourth protrusion 18 within the chamfers 23 reduces the influence of thermal expansion and contraction generated between metals, and further increases the fitting firmness after welding between the flange plate 2 and the valve body 1.

[0044] Those of ordinary skill in the art should understand that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
