Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to an aluminum alloy stop valve. Background Art

[0002] Aluminum alloy stop valve is an important control device in air conditioners, used to open and close the refrigerant channel in the air conditioning system. During the installation process, the stop valve and the joint nut (the nut is used to connect to the external pipeline) are hard-sealed. A large torque is required during installation, which causes the valve body to be subjected to a large shear force. However, the strength of aluminum alloy materials is relatively low. When the torque reaches the yield strength, the valve body will produce plastic deformation, resulting in structural changes in the first-line seal (the sealing matching position of the valve core and the valve port), loss of sealing effect, causing the valve body to fail, thereby affecting the sealing performance of the valve body. In addition, the valve body is susceptible to plastic deformation and metal fatigue, which causes the valve body to crack and affects the service life of the valve body. Utility Model Content

[0036] See also Figures 1 to 11The present application provides an aluminum alloy stop valve, which includes a valve body 10, and the valve body 10 includes a valve body 11, a reinforcement part 12 and a valve pipe 13. Among them, a valve cavity 111 and a valve port 112 are provided in the valve body 11. The valve pipe 13 is connected to the valve body 11. The reinforcement part 12 is arranged on the valve body 11 and is arranged corresponding to the position of the valve port 112. The reinforcement part 12 extends in the direction of the valve pipe 13 and protrudes from the outer side wall of the valve body 11, and the reinforcement part 12 is connected to the valve pipe 13. During the installation of the aluminum alloy stop valve, the valve pipe 13 needs to be inserted into the joint nut, and a wrench is used to apply a torque to the joint nut to tighten the joint nut, so that the valve pipe 13 and the joint nut are hard-sealed. A cap needs to be connected to the top of the valve body, and a wrench is used to apply a torque to the cap to tighten the cap. In the process of twisting the joint nut, the joint nut applies a force to the valve pipe 13, so that the valve pipe 13 will apply a force in the X-axis direction to the reinforcement part 12 and the valve body 11. When the cap is twisted, the cap will apply a force in the Y-axis direction to the valve body. Since the reinforcement portion 12 increases the cross-sectional area of ​​the valve body 11, the valve body 11 can withstand forces in two directions, and thus will not undergo plastic deformation, and will not cause the valve core and valve port 112 to be poorly sealed or the valve body 11 to crack, thereby effectively improving the sealing effect and service life of the aluminum alloy stop valve.

[0037] Furthermore, the reinforcement part 12 covers the outside of the valve body 11, and the reinforcement part 12 and the valve body 11 covered by it are rectangular as a whole. The rectangular shape mentioned above means that the reinforcement part 12 and the part of the valve body covered by the reinforcement part 12 are rectangular together, and the corners and edges of the rectangular body can also be chamfered to a certain extent without affecting the expression of the rectangular shape. Since the valve body 10 of the aluminum alloy stop valve is obtained by extrusion of the profile and then machining, the rectangular shape is easier to obtain, which effectively reduces the processing procedures, is conducive to intensive production, and saves costs.

[0038] Furthermore, the valve body 11, the reinforcement part 12 and the valve tube 13 are an integrated structure, and the integrated structure here refers to a one-time processing by machining methods such as turning and cutting. The valve cavity 111 penetrates the valve body 11 in the height direction Z of the valve body 11, the valve tube 13 is a hollow structure and communicates with the valve cavity 111, and the valve port 112 is arranged at a position close to the connection between the valve tube 13 and the valve cavity 111, and the position of the valve port 112 is the one-line seal mentioned above.

[0039] In this embodiment, the diameter of the valve body 11 is set to Φ1, and the diameter of the valve tube 13 is set to Φ2; the width of the reinforcement portion 12 is set to D1, and D1, Φ1, and Φ2 satisfy the relationship: D1>Φ1, D1>Φ2. That is, the width of the reinforcement portion 12 can completely cover the width of the valve body 11 and the width of the connection of the valve tube 13, thereby ensuring the strength of the connection between the valve tube 13 and the valve body 11 and reducing the possibility of deformation at this position.

[0040] Furthermore, the height of the reinforcement part 12 is set to H, and H and Φ2 satisfy the relationship: H>Φ2. That is, the height and width of the reinforcement part 12 will completely cover the valve tube 13, ensuring the strength of the connection between the valve tube 13 and the valve body 11 and reducing the possibility of deformation at this position.

[0041] Specifically, the valve pipe 13 includes a first connecting pipe 131 and a second connecting pipe 132. The reinforcement portion 12 includes a first body 121 and a second body 122. The first body 121 extends from the valve body 11 to the first connecting pipe 131 and is connected to the first connecting pipe 131. The second body 122 extends from the valve body 11 to the second connecting pipe 132 and is connected to the second connecting pipe 132. Preferably, the first connecting pipe 131 is coaxially arranged with the valve body 11, and the second connecting pipe 132 is arranged perpendicular to the valve body.

[0042] Furthermore, the cross section of the first body 121 is rectangular. Of course, in other embodiments, the cross section of the first body 121 can also be set to other shapes, which can be selected according to actual needs.

[0043] Furthermore, the cross section of the second body 122 is rectangular. Of course, in other embodiments, the cross section of the first body 121 can also be set to other shapes, which can be selected according to actual needs.

[0044] Specifically, a joint installation position 132a is provided on the second connecting pipe 132, and during installation, the joint nut is connected to the joint installation position 132a. The axis of the valve port 112 is coaxially arranged with the valve body 11, and the axis of the second connecting pipe 132 is arranged to intersect with the axis of the valve port 112.

[0045] In one embodiment, the valve tube 13 further includes a third connecting pipe 133, the third connecting pipe 133 is coaxially arranged with the second connecting pipe 132, and the first connecting pipe 131 is coaxially arranged with the valve body. The reinforcing portion 12 further includes a third body 123, the third body 123 extends from the valve body 11 to the third connecting pipe 133 and is connected to the third connecting pipe 133. Further, the cross section of the third body 123 is rectangular. Of course, in other embodiments, the cross section of the first body 121 can also be set to other shapes, which can be selected according to actual needs.

[0046] Furthermore, a cap mounting position 11a is provided on the top of the valve body 11, and the cap is connected to the cap mounting position 11a during installation. An extension portion 124 is provided on the reinforcement portion 12, and the extension portion 124 extends from the reinforcement portion 12 to the cap mounting position 11a, and the cross section of the extension portion 124 is rectangular. Of course, as in other embodiments, the cross section of the first body 121 can also be set to other shapes, which can be selected according to actual needs.

[0047] Furthermore, the aluminum alloy stop valve further includes a flange 20, which is disposed on the valve body 10. The flange 20 can be disposed on the valve body 11 or on the reinforcement portion 12, and the specific location can be selected according to actual use requirements.

[0048] See also Fig. 9 In one embodiment, the flange 20 and the valve body 10 are an integral structure, and the processing operation is simple.

[0049] See also Figure 1 and Fig.10 In other embodiments, the flange 20 and the valve body 10 are configured as a split structure. Specifically, a mounting portion 14 is provided on the valve body 10, and a flange hole 23 matching the mounting portion 14 is provided on the flange 20. When the cap is installed on the top of the valve body 11, the torque applied by the wrench to the cap will cause the flange 20 plate of the valve body 10 to be subjected to shear force. The presence of the flange hole 23 enables the flange 20 to withstand a large torsional force and is not prone to cracking. The mounting portion 14 can be provided on the valve body 11, or on the reinforcement portion 12, and the specific location can be selected according to actual use needs. In this embodiment, it is preferably provided on the reinforcement portion 12 to ensure that the force during the installation of the flange 20 will not cause torsional deformation of the valve body 11, thereby further improving the sealing effect and service life of the valve body 10.

[0050] For details, see Figure 1 , the flange 20 is sleeved on the mounting portion 14. Specifically, the mounting portion 14 and the reinforcing portion 12 are an integral structure, which is obtained by turning the reinforcing portion 12. The flange 20 and the mounting portion 14 can be fixedly connected by arc welding, gas welding, laser welding, etc. In this embodiment, laser welding is preferably used for firm welding. The welding position and welding length are selected according to actual conditions and are not limited here.

[0051] Alternatively, see Fig.10 The flange 20 is plugged into the mounting portion 14. Specifically, the mounting portion 14 is a ring groove disposed on the reinforcing portion 12.

[0052] See also Fig.11 The flange 20 includes a first body 21 and a second body 22, and the flange hole 23 includes a first half hole 231 and a second half hole 232. The first half hole 231 is provided on the first body 21, and the second half hole 232 is provided on the second body 22. The first body 21 and the second body 22 are plugged into the mounting portion 14 and then spliced ​​to form a complete flange 20. The first body 21 and the second body 22 can be fixedly connected by arc welding, gas welding, laser welding, etc. Under this structure, the flange 20 also plays the role of increasing the thickness of the valve body 11, further improving the strength of the valve body 11, and ensuring that the valve body 11 can withstand a large degree of joint torque.

[0053] In one embodiment, the length of the flange hole 23 is set to L1, and the length of the mounting portion 14 is set to L2, and L1 and L2 satisfy the relationship: 0.05mm≤L1-L2≤0.4mm. In addition, there is a certain gap between the flange hole 23 and the mounting portion 14 in the width direction, which ensures that the flange 20 can be easily installed on the mounting portion 14, and at the same time, the gap is not too large, ensuring that the flange 20 has sufficient strength after welding. The value of L1-L2 can be 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.35mm, 0.4mm, etc. Of course, the value of L1-L2 can also be selected according to the actual situation, which will not be described in detail here.

[0054] Furthermore, the width of the flange hole 23 is set to L3, and the width of the mounting portion 14 is set to L4, and L3 and L4 satisfy the relationship: 0.05mm≤L3-L4≤0.4mm. In addition, there is a certain gap between the flange hole 23 and the mounting portion 14 in the length direction, which ensures that the flange 20 can be easily installed on the mounting portion 14, and at the same time, the gap is not too large, ensuring that the flange 20 has sufficient strength after welding. The value of L3-L4 can be 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.35mm, 0.4mm, etc. Of course, the value of L3-L4 can also be selected according to the actual situation, which will not be described in detail here.

[0055] Preferably, the thickness of the flange 20 is set to D3, D3 ≥ 5 mm. The value of D3 can be 5 mm, 10 mm, 15 mm, 20 mm, etc. Of course, the value of D3 can also be selected according to the actual situation, which will not be described in detail here.

[0056] Specifically, the shape of the flange hole 23 can be set to, but not limited to, an ellipse, a rectangle, or a square. In the present embodiment, the flange hole 23 is set to be a rectangle, and preferably a rectangle.

[0057] Preferably, the inner corner 20a of the flange hole 23 is set as a chamfered structure. The chamfered structure means that the inner corner 20a is processed as a chamfer, and the angle of the chamfer can be selected according to actual needs and is not limited here. Since the profile extrusion cannot form a right angle, and then there will be a certain arc on the valve body 11, the reinforcement part 12, and the installation part 14, the inner corner 20a of the flange hole 23 is set as a chamfer to ensure that the flange 20 can be smoothly assembled with the valve body 10.

[0058] Preferably, the upper end 14a of the mounting portion 14 is also processed into a chamfer to facilitate the installation of the flange 20. The angle of the chamfer can be selected according to actual needs and is not limited here.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
