[0062] Now, refer to the attached Figure 1 To the attached Figure 8 Exemplary embodiments according to the present invention are described in more detail.

[0063] The first aspect of the present invention provides a valve installation structure 100. Figures 1 to 8 The valve mounting structure 100 includes a mounting seat 101 , a valve assembly 102 and a fastener 140 .

[0064] The mounting seat 101 has a mounting cavity 111, an inlet flow channel 118 and an outlet flow channel 119. The mounting cavity 111 is surrounded by a mounting wall 112. The mounting wall 112 forms a mounting portion 113 at the end of the mounting cavity 111 along the first direction D1. The outer peripheral surface of the mounting portion 113 is provided with an external thread 114. The valve assembly 102 includes a valve body 150, which is at least partially disposed in the mounting cavity 111 and is used to communicate between the inlet flow channel 118 and the outlet flow channel 119. The fastener 140 includes a connecting portion 143 and a limiting portion 144. The connecting portion 143 is provided with an internal thread 141 that cooperates with the external thread 114. The connecting portion 143 is connected to the mounting portion 113 by threaded cooperation, and the limiting portion 144 abuts against the valve body 150 to limit the movement of the valve assembly 102 along the first direction D1.

[0065] According to the valve mounting structure 100 of the utility model, the valve assembly 102 and the mounting seat 101 are fixed by means of the fastener 140, and the threaded structure and the flow channel in the valve assembly 102 are separated by means of the structure on the mounting seat 101, so that the debris generated when the fastener 140 is screwed can be prevented from entering the flow channel of the valve assembly 102, thereby ensuring the cleanliness of the flow channel and improving the product quality.

[0066] The first direction D1 and the second direction D2 may refer to the axial direction of the installation cavity 111 or the axial direction of the valve body 150 which are opposite to each other. That is, the first direction D1 and the second direction D2 are parallel to the central axis of the valve body 151 (to be described below).

[0067] Specifically, the valve installation structure 100 according to the present invention can be a separate valve product, or a combined structure in which the valve is installed on a device or a pipeline. For example, the installation seat 101 can be a component on a device that uses a valve.

[0068] In order to facilitate the processing of the external thread 114, the mounting seat 101 needs to protrude from the upper surface of the mounting seat 101. And the mounting seat 101 can be an independent component, as long as it has the mounting portion 113 that can protrude from the surface as described above. Alternatively, the mounting seat 101 can also be a separate component, so that the external thread 114 can be processed more conveniently.

[0069] For example, Figure 1 , Figure 2 , Figure 5 and Figure 6 , the mounting seat 101 may include a first valve seat 110 and a second valve seat 130. The first valve seat 110 has the above-mentioned mounting cavity 111, inlet flow channel 118 and outlet flow channel 119. The second valve seat 130 has a hollow cavity 131 that is arranged along the first direction D1 and the second direction D2, and the second valve seat 130 is also provided with an additional flow channel 132. The first valve seat 110 is arranged in the hollow cavity 131, and the mounting portion 113 protrudes from the surface of the end of the second valve seat 130 along the first direction D1, and the inlet flow channel 118 is connected to the additional flow channel 132. Such a setting makes it easier to process the external thread 114 of the mounting portion 113 of the first valve seat 110. In order to reduce the possibility of leakage between the inlet flow channel 118 of the first valve seat 110 and the additional flow channel 132 of the second valve seat 130, it is preferred to set a sealing ring between the inlet flow channel 118 and the additional flow channel 132.

[0070] Further, in order to facilitate the positioning and connection between the first valve seat 110 and the second valve seat 130, the first valve seat 110 is preferably provided with a first positioning hole 121, and the second valve seat 130 is preferably provided with a second positioning hole 134 corresponding to the position of the first positioning hole 121. When the first valve seat 110 is installed in the hollow cavity 131 of the second valve seat 130, the first positioning hole 121 is butted with the second positioning hole 134. Thus, the first valve seat 110 and the second valve seat 130 can be fixed by using the positioning pin 135 to pass through the second positioning hole 134 and extend into the first positioning hole 121. Among them, at least one of the second positioning hole 134 and the first positioning hole 121 is a screw hole, and the positioning pin 135 is correspondingly configured as a bolt.

[0071] Continue to refer Figure 1 , Figure 5 and Figure 6, the first valve seat 110 also has a first matching step portion 120, the radial dimension of which is greater than the radial dimension of the mounting portion 113. In other words, the first matching step portion 120 can be understood as a shoulder formed by radially inward contraction of the mounting portion 113. The second valve seat 130 also has a second matching step portion 133, which is located at the end opening of the hollow cavity 131 along the first direction D1, and the radial dimension of the hollow cavity 131 is greater than the radial dimension of the second matching step portion 133. Similarly, the second matching step portion 133 can be understood as a flange formed by radially inward contraction of the opening of the hollow cavity 131 along the first direction D1. The first valve seat 110 extends from the end opening of the hollow cavity 131 along the second direction D2 into the hollow cavity 131, so that the first matching step portion 120 abuts against the surface of the second matching step portion 133 located in the hollow cavity 131, for example, the upper surface of the first matching step portion 120 abuts against the lower surface of the second matching step portion 133 as shown in the figure, so as to form a similar snap-fit ​​structure. Such a setting not only facilitates the assembly between the first valve seat 110 and the second valve seat 130, but also further uses the two steps to block the passage of debris generated by the external thread 114 of the mounting portion 113 from entering the flow channel, specifically, it can prevent debris from entering the flow channel through the gap between the first valve seat 110 and the second valve seat 130.

[0072] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The valve assembly 102 includes a valve body 150, which includes a valve body portion 151, a valve mouth portion 155, and a valve core portion 162. The valve body portion 151 is provided with a flow hole 154, and the flow hole 154 is connected to the inlet flow channel 118. The surface of the valve body portion 151 facing the first direction D1 is configured as a fastening surface 161. When the fastener 140 is tightened, the fastener 140 abuts against the fastening surface 161 to provide a fastening force along the second direction D2 to the valve body 150.

[0073] The mounting wall 112 is provided with a mounting step portion 115 at the end of the mounting cavity 111 along the second direction D2, and the valve body 150 is provided with a mounting flange 156 at the end along the second direction D2. The mounting flange 156 abuts against the mounting step portion 115. When the fastener 140 abuts against the fastening surface 161, the mounting step portion 115 provides a resistance force along the first direction D1 to the mounting flange 156, so that the valve assembly 102 is fixed between the fastener 140 and the mounting step portion 115.

[0074] The valve mouth portion 155 is connected to the valve body portion 151, and the two are preferably connected by welding and / or interference fit. The end of the valve mouth portion 155 along the second direction D2 forms a mounting flange 156, and the mounting flange 156 forms a valve port 158, and the valve port 158 ​​is connected to the outlet flow channel 119. The valve core portion 162 is provided in the valve body portion 151, and the valve core portion 162 is configured to be movable along the first direction D1 and the second direction D2, and when the valve core portion 162 moves along the second direction D2 to abut against the valve mouth portion 155, the valve core portion 162 can block the flow hole 154.

[0075] The valve body 150 has a sealing shaft shoulder 157, which is arranged around the mounting flange 156. Specifically, the sealing shaft shoulder 157 is arranged at the valve mouth 155, adjacent to the mounting flange 156, and the radial dimension of the sealing shaft shoulder 157 is larger than the radial dimension of the mounting flange 156. The mounting wall 112 is also provided with a sealing step 116, which is adjacent to the mounting step 115. The sealing shaft shoulder 157 is arranged at a distance from the sealing step 116, and an inner leakage seal 117 is connected between the sealing shaft shoulder 157 and the sealing step 116 to prevent the liquid from leaking from the gap on the outer peripheral surface of the valve mouth 155 when the valve assembly 102 is in a closed state, that is, when the valve core 162 blocks the flow hole 154 of the valve body 151. When the fastener 140 is tightened, the inner leakage seal 117 is in a compressed state, thereby providing a reverse pre-tightening force to the fastener 140 to prevent the fastener 140 from loosening and improve the stability of the installation. Preferably, when the fastener 140 is tightened, the inner leakage seal 117 is compressed by 20%.

[0076] The outer circumference of the valve body 150 and / or the inner circumference of the mounting wall 112 is provided with an external leakage sealing groove 152, and the external leakage sealing groove 152 is provided with an external leakage sealing member 153. In the embodiment shown in the figure, the external leakage sealing groove 152 is provided on the outer circumference of the valve body 151. In an optional embodiment, the external leakage sealing groove 152 can be provided on the inner circumference of the mounting cavity 111 of the first valve seat 110. The external leakage sealing member 153 is connected to both the outer circumference of the valve body 151 and the inner circumference of the mounting wall 112 to prevent the liquid from leaking from the gap between the valve body 151 and the first valve seat 110 when the valve assembly 102 is in a closed state, that is, when the valve core 162 blocks the flow hole 154 of the valve body 151. Preferably, the external leakage sealing member 153 can also be in a compressed state to provide a reverse pre-tightening force to the above-mentioned positioning pin 135 to prevent it from loosening.

[0077] refer to Figure 1 , Figure 2 and Figure 8The valve body 150 further includes a connecting portion 159, which is disposed at the end of the valve body portion 151 along the first direction D1 and extends along the first direction D1, and the radial dimension of the connecting portion 159 is smaller than the radial dimension of the valve body portion 151. In other words, the connecting portion 159 protrudes outward from the end of the mounting portion 113 along the first direction D1. A connecting member 160 that can move along the first direction D1 and the second direction D2 is disposed in the connecting portion 159, and the connecting member 160 is connected to the valve core portion 162 to control the movement of the valve core portion 162, wherein the connecting member 160 can be understood as a control member of the valve core portion 162, which can be connected to a certain control device for the operator to operate the valve opening and closing.

[0078] The fastener 140 is provided with a through hole 142, and the radial dimension of the connecting portion 159 is smaller than the radial dimension of the through hole 142, so that the connecting portion 159 is arranged through the through hole 142. In the illustrated embodiment, the through hole 142 is arranged in the middle of the limiting portion 144. The radial dimension of the through hole 142 is smaller than the radial dimension of the valve body portion 151. It can be understood that the radial dimension of the connecting portion 159 is smaller than the radial dimension of the valve body portion 151 to form a shoulder. Thus, the fastener 140 can be connected to the mounting portion 113 and the fastening surface 161 on the valve body portion 151. Thus, when the fastener 140 is tightened, the inner periphery of the through hole 142 of the fastener 140 can press the valve body portion 151 along the second direction D2, thereby improving the firmness of the installation. It can be understood that the shoulder surface of the valve body portion 151 (the above-mentioned fastening surface 161) is preferably flush with the surface of the mounting portion 113 of the first valve seat 110 facing the first direction D1.

[0079] As an optional embodiment, the valve assembly 102 can be a manual valve, in which case the connector 160 can be constructed as a screw that can be raised and lowered by rotation, and the top end of the screw can be connected to an operating unit. Alternatively, the valve assembly 102 can be a pneumatic valve, and the connector 160 is connected to a pneumatic component.

[0080] As a preferred embodiment, Figure 1 and Figure 2 As shown in , the valve assembly 102 is configured as a solenoid valve, which further includes a solenoid assembly 170. The solenoid assembly 170 is disposed at the connecting portion 159, and the solenoid assembly 170 includes a solenoid coil 171 and a moving iron core 172, wherein the moving iron core 172 is connected to the connecting member 160. Preferably, the solenoid valve is configured as a long-open solenoid valve, that is, a compressed resilient member 163 may be disposed between the valve core portion 162 and the valve mouth portion 155, so that when no power is supplied, the resilient member 163 may lift up the valve core portion 162, so that the flow hole 154 is connected to the inlet flow channel 118 and the outlet flow channel 119, thereby making the solenoid valve in an open state.

[0081] The second aspect of the present invention provides a thermal management system, comprising the valve mounting structure 100 of the first aspect, wherein the pipeline or equipment in the thermal management system can be constructed as the mounting seat 101 of the first aspect.

[0082] According to the thermal management system of the present invention, the valve installation structure 100 of the first aspect is provided, so the cleanliness inside the pipeline of the thermal management system is high and the service life is long.

[0083] A third aspect of the present application provides a vehicle, comprising the valve mounting structure 100 of the first aspect and / or comprising the thermal management system of the second aspect.

[0084] The vehicle according to the utility model has the valve installation structure 100 of the first aspect and / or the thermal management system of the second aspect, and thus has technical effects similar to those of the valve installation structure 100 of the first aspect and / or the thermal management system of the second aspect.
