Description

Technical Field

[0001] This application relates to the field of valves, and more specifically to a valve for an internal combustion engine. Background Technology

[0002] Valves are commonly used in internal combustion engines to create different cooling circuits between different components to be cooled. Specifically, a valve includes a housing, a shaft, and a valve body. The housing forms a housing cavity and has at least three ports. These at least three ports are used to connect to different components in the internal combustion engine to form different cooling circuits. A partition plate is provided in the housing, dividing the housing cavity into a left cavity and a right cavity. The left cavity houses a drive component, and the right cavity houses the valve body, which controls the flow of coolant. The partition plate has holes for accommodating the shaft. The drive component is connected to the valve body via the shaft, enabling the drive component to rotate the valve body. The valve body has at least one hole so that when the valve body rotates, it can selectively communicate with one or more ports of the housing, thereby forming different cooling circuits.

[0003] The valve also includes a seal, which is located between the shaft and the partition plate to prevent the coolant contained in the right cavity from entering the drive component along the shaft, so as to prevent the drive component from short-circuiting, corroding, or wearing due to the erosion of the coolant. Summary of the Invention

[0004] Exemplary embodiments of this application can solve at least some of the above-mentioned problems. For example, this application provides a valve including a housing body, a partition plate, and a collecting device. The housing body defines a housing cavity extending through the housing body. The partition plate is disposed in the housing cavity to divide it into a left cavity and a right cavity. A leakage channel is provided in the partition plate. It extends along the partition plate, through the housing body, and forms a lower port and an upper port of the leakage channel on the housing body. The collecting device includes a lower component, an upper component, and a connector connecting the lower component and the upper component. The lower component is configured to cover the lower port of the leakage channel, and the lower component includes a collecting cavity communicating with the lower port of the leakage channel. A lower assembly assembly is provided at the lower part of the lower component and the housing body, and an upper assembly assembly is provided at the upper part of the upper component and the housing body. The lower component and the upper component are assembled into position on the housing body by the lower assembly assembly, the upper assembly assembly, and the connector.

[0005] According to the valve of this application, the lower housing assembly and the upper housing assembly are symmetrically arranged with respect to the axis of the housing body.

[0006] According to the valve of this application, the lower assembly includes a lower housing assembly portion disposed on the housing body and a lower component assembly portion disposed on the lower component. The upper assembly includes an upper housing assembly portion disposed on the housing body and an upper component assembly portion disposed on the upper component.

[0007] According to the valve of this application, the lower housing assembly portion and the upper housing assembly portion protrude from the outer surface of the housing body. The lower component assembly portion is a recess located on the lower component, and the upper component assembly portion is a recess located on the upper component.

[0008] According to the valve of this application, the lower housing assembly and the upper housing assembly are both wedge-shaped. The wedge-shaped lower housing assembly includes a first blocking surface and a first inclined surface connected to the first blocking surface, the first inclined surface being closer to the connector than the first blocking surface. The wedge-shaped lower housing assembly also includes a second blocking surface and a second inclined surface connected to the second blocking surface, the second inclined surface being closer to the connector than the second blocking surface.

[0009] According to the valve of this application, the housing body is provided with a left limiting member and a right limiting member, the left limiting member and the right limiting member respectively protruding from the outer surface of the housing body, thereby forming a connecting member receiving part between the left limiting member and the right limiting member to receive the connecting member.

[0010] According to the valve of this application, the collecting device is made of a single piece of plastic.

[0011] According to the valve of this application, the partition plate is provided with a shaft receiving hole that extends laterally through the partition plate for accommodating a shaft. The shaft receiving hole is connected to the leakage channel.

[0012] According to the valve of this application, the left cavity is used to accommodate the drive component, and the right cavity is used to accommodate the valve body of the valve.

[0013] According to the valve of this application, the housing body further includes a left sealing plate and a right sealing plate, which are respectively connected to the left and right surfaces of a partition plate around the shaft receiving hole. The valve also includes a shaft, a first sealing element, and a second sealing element. The shaft passes through the shaft receiving hole. The first sealing element is annular, with its inner wall abutting against the shaft and its outer wall abutting against the left sealing plate, thereby sealing the left cavity and the leakage channel through the first sealing element. The second sealing element is annular, with its inner wall abutting against the shaft and its outer wall abutting against the right sealing plate, thereby sealing the leakage channel and the right cavity through the second sealing element.

[0014] The coolant leaking from the valve provided in this application can be collected by a collection device, preventing it from dripping onto the outside of the valve. The collection device provided in this application can be molded, making it simple and easy to manufacture, thus saving manufacturing time. The collection device is installed onto the housing using its own structure and the structure on the housing, without requiring other fastening components (e.g., nuts, bolts, etc.), which reduces the number of assembly parts and saves costs.

[0032] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although terms indicating direction, such as "up," "down," "left," "right," "inner," and "outer," are used herein to describe various exemplary structural parts and elements, their use is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings.

[0033] Figure 1A This is a top-down perspective view of a valve 100 according to one embodiment of this application. Figure 1B yes Figure 1A The valve 100 shown is a perspective view from bottom to top. Figure 1C yes Figure 1A The bottom view of valve 100 shown. Figure 1D yes Figure 1A The exploded view of valve 100 is shown. Figure 1A-1DAs shown, valve 100 includes a housing 102, a shaft 116, a valve body 118, a first seal 112, and a second seal 114. The shaft 116, valve body 118, first seal 112, and second seal 114 are disposed within the housing 102. The positional relationship of the shaft 116, valve body 118, first seal 112, and second seal 114 within the housing 102 will be determined by… Figure 2 Detailed introduction.

[0034] The housing 102 includes a housing body 122, a first pipe 141, a second pipe 142, and a third pipe 143. Specifically, the housing body 122 is generally a hollow cylinder. The housing body 122 defines a housing cavity. The housing cavity extends laterally through the housing body 122. The first pipe 141, the second pipe 142, and the third pipe 143 are disposed outside the housing body 122 and are all hollow pipes. The first pipe 141, the second pipe 142, and the third pipe 143 are in fluid communication with the housing cavity, thereby allowing fluid (e.g., coolant) contained in the housing cavity to flow out of the housing 102 through the first pipe 141, the second pipe 142, and the third pipe 143, or allowing fluid (e.g., coolant) to flow into the housing 102 through the first pipe 141, the second pipe 142, and the third pipe 143. The first pipe 141, the second pipe 142, and the third pipe 143 can be connected to components to be cooled (not shown) to form different cooling circuits for cooling different components.

[0035] Figure 2 yes Figure 1A The valve 100 shown is along Figure 1C A cross-sectional view along line AA shows the specific positional relationship of shaft 116, valve body 118, first seal 112, and second seal 114 within housing 102. (See diagram below.) Figure 2 As shown, the housing 102 also includes a partition plate 206. The partition plate 206 is disposed in the housing cavity and divides the housing cavity into a left cavity 222 and a right cavity 224. The left cavity 222 is used to accommodate a drive component (not shown). The right cavity 224 is used to accommodate a valve body 118 for controlling the flow direction of coolant.

[0036] A leakage channel 208 is provided in the partition plate 206. The leakage channel 208 extends along the partition plate 206, penetrates the housing body 122, and forms a lower port 212 and an upper port 214 on the housing body 122. The partition plate 206 also has a shaft receiving hole penetrating the partition plate 206 for accommodating a shaft 116. The shaft receiving hole is in fluid communication with the leakage channel 208. As an example, the partition plate 206 is vertically disposed in the housing cavity, the leakage channel 208 vertically penetrates the partition plate 206, and the shaft receiving hole transversely penetrates the partition plate 206.

[0037] The housing 102 also includes a left sealing plate 232 and a right sealing plate 234. The left sealing plate 232 is disposed around the shaft receiving hole and is connected to the left surface (i.e., the left side) of the partition plate 206. The right sealing plate 234 is also disposed around the shaft receiving hole and is connected to the right surface (i.e., the right side) of the partition plate 206.

[0038] The shaft 116 of valve 100 is generally cylindrical and rotatable about its own axis. Shaft 116 passes through a shaft receiving hole and is positioned transversely within the housing cavity. The left end of shaft 116 enters the left cavity 222 to connect with a drive component (not shown) located in the left cavity 222. The right end of shaft 116 enters the right cavity 224 to connect with the valve body 118 located in the right cavity 224. When the drive component drives shaft 116 to rotate, shaft 116 can cause valve body 118 to rotate together about its axis.

[0039] Both the first seal 112 and the second seal 114 of valve 100 are annular. The outer wall of the first seal 112 abuts against the left sealing plate 232, and the inner wall of the first seal 112 abuts against the shaft 116, thereby enabling the first seal 112 to form a seal between the left cavity 222 and the leakage channel 208. The outer wall of the second seal 114 abuts against the right sealing plate 234, and the inner wall of the second seal 114 abuts against the shaft 116, thereby enabling the second seal 114 to form a seal between the leakage channel 208 and the right cavity 224.

[0040] The valve body 118 of valve 100 is hollow, and the valve body 118 has three openings (see...). Figure 1D When at least one of the three openings on the valve body 118 is aligned with at least one of the first pipe 141, the second pipe 142, and the third pipe 143 on the housing 102, coolant in the right cavity 224 can flow into or out of the valve 100 through the first pipe 141, the second pipe 142, and / or the third pipe 143 aligned with the opening on the valve body 118.

[0041] It should be noted that this application is not intended to restrict the installation sequence and connection relationship between shaft 116, valve body 118, first seal 112 and second seal 114, and any installation sequence and connection relationship is within the protection scope of this application.

[0042] In addition, continue to refer to Figure 1A-1D The valve 100 also includes a collection device 104. The collection device 104 is mounted on the outside of the housing 102. The collection device 104 includes a lower component 152, an upper component 154, and a connector 156. The connector 156 connects the lower component 152 and the upper component 154. The lower component 152 covers the lower port 212 of the leakage channel 208. The upper component 154 covers the upper port 214 of the leakage channel 208.

[0043] In conventional valves, coolant contained in the right cavity may flow along the shaft into the left cavity, causing the coolant to come into contact with the drive component located in the left cavity, resulting in short circuits, corrosion, and wear of the drive component. In the valve 100 of this application, a leakage channel 208 is provided in the housing 102, allowing coolant to flow out of the housing cavity through the leakage channel 208 when coolant contained in the right cavity 224 leaks along the shaft 116 into the left cavity 222, thus preventing coolant from entering the left cavity 222. Furthermore, the collecting device 104 in the valve 100 of this application can cover the lower port 212 of the leakage channel to collect coolant flowing out from the lower port 212 of the leakage channel 208, preventing coolant from contacting other components (e.g., components to be cooled) located outside the valve 100.

[0044] Figure 3A yes Figure 1A The shown is a perspective view of the housing 102 from bottom to top. Figure 3B yes Figure 1A The above is a perspective view of the housing 102 from above. Figure 3C yes Figure 1A The housing 102 shown is along Figure 1C A vertical sectional view along line DD to show the structure on housing 102 that mates with collection device 104. (See attached image.) Figures 3A-3C As shown, the housing 102 includes a left limiting member 312 and a right limiting member 314 to restrict the left and right movement of the connecting member 156 of the collecting device 104. Specifically, the left limiting member 312 is disposed on the housing body 122 and protrudes from the outer surface of the housing body 122. The left limiting member 312 extends circumferentially along the housing body 122. The left limiting member 312 is disposed approximately on the same circumferential direction as the lower port 212 and the upper port 214 of the leakage channel of the housing body 122. The right limiting member 314 includes protrusions 331 and 332 disposed on the same circumferential direction of the housing body 122. Protrusions 331 and 332 also protrude from the outer surface of the housing body 122. The left limiting member 312 and the right limiting member 314 are spaced a certain distance apart along the length direction of the housing body 122 (i.e., the axial direction of the housing body 122) to define the connector receiving part 360 between the left limiting member 312 and the right limiting member 314 to receive the connector 156 in the collecting device 104.

[0045] It should be noted that although the right limiting member 314 in this application includes two protrusions, those skilled in the art will understand that the right limiting member 314 may include any other number of protrusions. Furthermore, although the left limiting member 312 in this application is a structure that extends circumferentially along the housing body 122 and protrudes from the housing body 122, those skilled in the art will understand that the left limiting member 312 may also be formed by at least two protrusions.

[0046] It should also be noted that although the connector receiving portion 360 in this application is defined by the left limiting member 312 and the right limiting member 314 protruding from the housing body 122, those skilled in the art will understand that the connector receiving portion 360 may also be formed by the housing body 122 being recessed inward.

[0047] Continue to refer to Figure 3A and 3C The housing 102 also includes a lower housing assembly 302 for engaging with the lower component 152 of the collecting device 104, thereby mounting the lower component 152 onto the housing 102. The lower housing assembly 302 is located on the outside of the housing body 122 and protrudes from the outer surface of the housing body 122. The lower housing assembly 302 is generally located to the right of the lower port 212 of the leakage channel. Specifically, the lower housing assembly 302 is wedge-shaped. The wedge-shaped lower housing assembly 302 includes a first blocking surface 344 and a first inclined surface 342 perpendicular to the outer surface of the housing body 122. The first blocking surface 344 extends generally radially outward along the housing body 122. The first inclined surface 342 is connected to the first blocking surface 344, and the first inclined surface 342 is closer to the connector receiving portion 360 than the first blocking surface 344. In other words, when the collecting device 104 is mounted on the housing 102, the first inclined surface 342 is closer to the connector 156 than the first blocking surface 344. The lower assembly portion 302 of the housing is approximately triangular in the radial section of the housing body 122 (see...). Figure 3C ).

[0048] Continue to refer to Figure 3B and 3CThe housing 102 also includes an upper housing mounting portion 304 for engaging with the upper component 154 of the collecting device 104, thereby mounting the upper component 154 to the housing 102. The upper housing mounting portion 304 and the lower housing mounting portion 302 are symmetrically arranged with respect to the length direction of the housing body 122 (i.e., the axis of the housing body 122). Specifically, the upper housing mounting portion 304 is located on the outside of the housing body 122 and protrudes from the outer surface of the housing body 122. The upper housing mounting portion 304 is located approximately to the right of the upper port 214 of the leakage channel. The upper housing mounting portion 304 is wedge-shaped. The wedge-shaped upper housing mounting portion 304 includes a second blocking surface 354 and a second inclined surface 352 perpendicular to the outer surface of the housing body 122. The second blocking surface 354 extends approximately radially outward along the housing body 122. The second inclined surface 352 is connected to the second blocking surface 354, and the second inclined surface 352 is closer to the connector receiving portion 360 than the second blocking surface 354. In other words, when the collecting device 104 is mounted on the housing 102, the second inclined surface 352 is closer to the connector 156 than the second blocking surface 354. The mounting portion 304 on the housing is approximately triangular in radial section of the housing body 122 (see...). Figure 3C ).

[0049] Although the upper housing assembly 304 and the lower housing assembly 302 in this application are both wedge-shaped, those skilled in the art will understand that any shape of the upper housing assembly 304 and the lower housing assembly 302 protruding from the housing body 122 is within the protection scope of this application.

[0050] Figure 4 This is a perspective view of the collecting device 104 shown in Figure 1. Figure 4As shown, the collection device 104 includes a lower component 152, an upper component 154, and a connector 156. The connector 156 is generally an arc-shaped strip. One end of the connector 156 is connected to the lower component 152, and the other end is connected to the upper component 154, thereby connecting the components 152 and 154 together. The lower component 152 can mate with the lower housing assembly 302 of the housing 102, the upper component 154 can mate with the upper housing assembly 304 of the housing 102, and the connector 156 can be received by the connector receiving part 360, thereby allowing the collection device 104 to be mounted on the housing 102. As an example, the collection device 104 of this application is integrally molded from plastic. As another example, the lower component 152, upper component 154, and connector 156 in the collection device 104 of this application can also be connected by a connecting member. The collecting device 104 of this application is configured such that when the lower component 152 and / or the upper component 154 is subjected to an external force, the collecting device 104 can deform, thereby causing the lower component 152 and the upper component 154 to move away from each other. Furthermore, the collecting device 104 is also configured such that when the external force is removed, the deformation caused by the external force disappears, and the collecting device 104 returns to its original shape.

[0051] Figure 5A yes Figure 4 The lower component 152 shown is a side view from the inside to the outside. Figure 5B yes Figure 5A The lower component 152 shown is along Figure 5A A cross-sectional view along the BB line. (Example) Figures 5A-5B As shown, the lower component 152 is generally a block with a certain thickness. One end 511 is used to connect to one end of the connector 156, and the other end is a free end 512. A lower component mounting portion 502 is provided on the lower component 152. The lower component mounting portion 502 is a recess located on the lower component 152. In other words, the lower component mounting portion 502 is formed by recessing inward from the inner surface 501 of the lower component 152. The lower component mounting portion 502 is wedge-shaped. That is, the cross-section of the lower component mounting portion 502 along the length direction of the connector 156 (i.e., along...) Figure 5AThe cross-section of the BB line is triangular, which allows it to mate with the lower assembly portion 302 of the housing. More specifically, the lower assembly portion 502 has a lower assembly blocking surface 524 and a lower assembly inclined surface 522. The lower assembly blocking surface 524 is substantially perpendicular to the inner surface 501 of the lower component 152. The lower assembly inclined surface 522 is connected to the lower assembly blocking surface 524, and the lower assembly blocking surface 524 is closer to the free end 512 than the lower assembly inclined surface 522. Therefore, the shape of the lower assembly portion 502 is the same as that of the lower assembly portion 302 of the housing 102. The shape of the lower assembly portion 502 mates with the shape of the lower assembly portion 302 of the housing so that the lower assembly portion 502 can receive the lower assembly portion 302 of the housing.

[0052] The lower component 152 is also provided with a collection cavity 504. The collection cavity 504 is located in a recess on the lower component 152. In other words, the collection cavity 504 is formed by an inward recess from the inner surface 501 of the lower component 152. The collection cavity 504 is configured to contain coolant leaking from the lower port 212 of the leakage channel 208. When the collection device 104 is installed on the housing 102, the collection cavity 504 can be aligned with the lower port 212 of the leakage channel to receive coolant leaking from the lower port 212 of the leakage channel 208.

[0053] When valve 100 is used in an internal combustion engine, collection chamber 504 can be further configured to contain coolant leaking from the lower port 212 of leakage passage 208 within a preset time. This is because the temperature in the internal combustion engine is high, and the coolant contained in collection chamber 504 will evaporate at least partially due to the high ambient temperature.

[0054] Figure 6A yes Figure 4 The upper component 154 shown is a side view from the inside to the outside. Figure 6B yes Figure 6A The upper component 154 shown is along Figure 6A A cross-sectional view along the CC line. (Example) Figures 6A-6B As shown, the upper component 154 is generally a block with a certain thickness. One end 611 is used to connect to one end of the connector 156, and the other end is a free end 612. The upper component 154 is provided with an upper component mounting portion 602. The upper component mounting portion 602 is a recess located on the upper component 154. In other words, the upper component mounting portion 602 is formed by recessing inward from the inner surface 601 of the upper component 154. The upper component mounting portion 602 is wedge-shaped. That is, the cross-section of the upper component mounting portion 602 along the length direction of the connector 156 (i.e., along...) Figure 6AThe cross-section of the CC line is triangular, which allows it to mate with the upper assembly portion 304 of the housing. More specifically, the upper component assembly portion 602 has an upper component blocking surface 624 and an upper component inclined surface 622. The upper component blocking surface 624 is substantially perpendicular to the inner surface 601 of the upper component 154. The upper component inclined surface 622 is connected to the upper component blocking surface 624, and the upper component blocking surface 624 is closer to the free end 612 than the upper component inclined surface 622. Therefore, the upper component assembly portion 602 has the same shape as the housing upper assembly portion 304 of the housing 102. The upper component assembly portion 602 mates with the housing upper assembly portion 304 in such a way that the upper component assembly portion 602 can receive the housing upper assembly portion 304.

[0055] In addition, the upper component 154 is also provided with an additional cavity 604. The formation of the additional cavity 604 is similar to that of the collection cavity 504, and will not be described again here. The upper component 154 is configured such that when the collection device 104 is installed on the housing 102, the upper component 154 can be aligned with the upper port 214 of the leakage channel, so that the upper component 154 can cover the upper port 214 of the leakage channel, thereby preventing dust and other particles in the air from entering the housing cavity through the leakage channel 208.

[0056] Although the upper component 154 is provided with an additional cavity 604 in the embodiments of this application, those skilled in the art will understand that the upper component 154 may not be provided with an additional cavity 604.

[0057] Figures 7A-7C yes Figure 1A The diagram shows the process of installing the collection device 104 into the housing 102. Figure 7A The relative position of the collecting device 104 when it is not installed in the housing 102 is shown. Figure 7B The image shows the state of the collection device 104 as it is ready to be installed into the housing 102. Figure 7C The relative positions of the collecting device 104 when it is installed in the housing 102 are shown. Specifically, as Figure 7A As shown, when the collecting device 104 needs to be installed onto the housing 102, the collecting device 104 needs to be brought close to the housing 102, and the connector 156 of the collecting device 104 needs to be aligned with the connector receiving portion 360 on the housing 102. Figure 7BAs shown, the operator applies upward and downward external forces F to the upper part 154 and lower part 152 of the collecting device 104, respectively, causing deformation of the collecting device 104 (especially the connecting member 156). The lower part 152 and upper part 154 in the deformed collecting device 104 move away from each other. More specifically, the distance between the lower part assembly portion 502 and the upper part assembly portion 602 in the longitudinal direction of the collecting device 104 (i.e., the length of the curve in the longitudinal direction) is greater than the circumferential distance between the lower housing assembly portion 302 and the upper housing assembly portion 304 of the housing 102 (i.e., the length in the circumferential direction). At this time, as... Figure 7C As shown, the operator can engage the lower component assembly 502 with the lower housing assembly 302, engage the upper component assembly 602 with the upper housing assembly 304, and engage the connector 156 with the connector receiving portion 360 on the housing 102, so that the collecting device 104 is assembled in place on the housing 102. Finally, the operator removes the force applied to the collecting device 104, and the collecting device 104 can be held in place on the housing 102.

[0058] When the collecting device 104 is mounted on the housing 102, the upper component 154 can be supported by the housing 102. The connector 156 can apply an upward force to the lower component 152, thereby overcoming the weight of the lower component 152 and keeping it in place. The connector 156 is housed in the connector receiving part 360, and its lateral movement is limited by the left limiting member 312 and the right limiting member 314. After the collecting device 104 is assembled in place on the housing 102, the collecting device 104 is not easily detached from the housing 102 due to external factors such as vibration.

[0059] Figure 8 This is a schematic diagram of another process for installing the collecting device 104 onto the housing 102. (See diagram below.) Figure 8 As shown, the operator can press the collection device 104 towards the housing 102 without applying upward or downward external forces to the collection device 104. For example, by pressing the collection device 104 along... Figure 8The arrows indicate movement in the direction shown. The collecting device 104 is generally arc-shaped, so when the upper component 154 and lower component 152 of the collecting device 104 contact the housing 102, the upper component 154 and lower component 152 will respectively contact the upper mounting portion 304 and the lower mounting portion 302 of the housing. Since the upper mounting portion 304 and the lower mounting portion 302 of the housing respectively have a first inclined surface 342 and a second inclined surface 352, the first inclined surface 342 and the second inclined surface 352 will guide the lower component 152 and the upper component 154 respectively, causing the lower component 152 and the upper component 154 to open outwards (i.e., the lower component 152 and the upper component 154 move away from each other). When the lower component blocking surface 524 and the upper component inclined surface 622 in the lower component 152 and the upper component 154 respectively pass over the first blocking surface 344 and the second blocking surface 354, the first inclined surface 342 and the second inclined surface 352 no longer exert an outward opening force on the collecting device 104. At this point, the lower component assembly 502 engages with the lower housing assembly 302, the upper component assembly 602 engages with the upper housing assembly 304, and the connector 156 is accommodated in the connector receiving portion 360 on the housing 102. The collecting device 104 is then assembled into place on the housing 102. This operation method is simple, requiring only one step for installation, and can be completed by the operator with one hand, greatly increasing the installation efficiency of the collecting device 104 onto the housing 102.

[0060] It should be noted that although the upper housing assembly portion 304 and the lower housing assembly portion 302 in this application are symmetrically arranged with respect to the length direction of the housing body 122 (i.e., the axis of the housing body 122), the upper housing assembly portion 304 and the lower housing assembly portion 302 may not be symmetrically arranged with respect to the length direction of the housing body 122 (i.e., the axis of the housing body 122), as long as the upper housing assembly portion 304 and the lower housing assembly portion 302 are arranged in the same circumferential direction.

[0061] It should also be noted that, in this application, the lower housing assembly 302 and the lower component assembly 502 are referred to as the lower assembly assembly, and the upper housing assembly 304 and the upper component assembly 602 are referred to as the upper assembly assembly. The lower component 152 and the upper component 154 can be installed on the housing body 122 via the lower assembly assembly, the upper assembly assembly, and the connector 156.

[0062] Although the components in the upper and lower assembly assemblies of this application are wedge-shaped, those skilled in the art will understand that the components in the upper and lower assembly assemblies can be of any shape.

[0063] Although in this application, the upper housing assembly portion 304 and the lower housing assembly portion 302 protrude from the housing body 122, and the lower component assembly portion 502 and the upper component assembly portion 602 are recessed portions, those skilled in the art will understand that the upper housing assembly portion 304 and the lower housing assembly portion 302 can also be configured as recessed portions, and the lower component assembly portion 502 and the upper component assembly portion 602 can protrude from the housing body 122. It is sufficient that the lower housing assembly portion 302 and the lower component assembly portion 502 in the lower assembly assembly can mate, and the upper housing assembly portion 304 and the upper component assembly portion 602 in the upper assembly assembly can mate.

[0064] The coolant leaking from the valve 100 provided in this application can be collected by the collecting device 104, preventing it from dripping onto the outside of the valve 100. Furthermore, the collecting device 104 provided in this application can be molded, making it simple and easy to manufacture, thus saving manufacturing time. The collecting device 104 is mounted to the housing 102 by means of its own structure and the structure on the housing 102, without requiring other fastening components (e.g., nuts, bolts, etc.), which reduces the number of assembly parts and saves costs.

[0065] Although only some features of this application have been illustrated and described herein, many modifications and variations will be apparent to those skilled in the art. Therefore, it should be understood that the appended claims are intended to cover all such modifications and variations that fall within the essential spirit and scope of this application.
