DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 to Figure 8, which is the first embodiment of the present invention, and provides a valve for a waste heat recovery device, which can achieve the effect of quickly fixing the valve body 101 and the waste heat recovery pipeline 104, and comprises a supporting component 100, including a valve body 101, a first flange 102 arranged at the left and right ends of the valve body 101, a second flange 103 arranged outside the first flange 102, and a waste heat recovery pipeline 104 arranged on the second flange 103; a limiting component 200, including an extruded part arranged on the first flange 102 The pressing component 201 includes a locking component 202 disposed on the pressing component 201, a guiding component 203 disposed on the locking component 202, a transmission component 204 disposed on the guiding component 203, and a reset component 205 disposed on the transmission component 204; the closing component 300 includes a sealing component 301 disposed on the second flange 103, a rotating component 302 disposed on the sealing component 301, a toggle component 303 disposed on the rotating component 302, and a moving component 304 disposed on the toggle component 303.

[0034] Specifically, the first flange 102 and the second flange 103 are both provided with an inner groove, and a sealing ring is provided in the inner groove, so as to achieve sealing between the first flange 102 and the second flange 103. Here, the first flange 102 and the second flange 103 are both provided with threaded holes, and the waste heat recovery pipe 104 here is connected to the waste heat recovery and utilization device.

[0035] Further, the extrusion assembly 201 includes a plurality of mounting boxes 201a fixedly connected to the first flange 102, the outer ends of the plurality of mounting boxes 201a are all open, a slider 201b is slidably connected inside the mounting box 201a, the slider 201b is elastically connected to the inner wall of the mounting box 201a through a first spring 201c, and the second flange 103 is provided with a plurality of mounting grooves 201d that cooperate with the slider 201b mounting box 201a; the clamping assembly 202 includes a first mounting port 202a provided on the mounting box 201a, and the slider 201b is provided with a second mounting port 202b that cooperates with the first mounting port 202a. An insert block 202c is provided in the installation port 202a, and a card slot 202d matching the installation slot 201d is provided on the inner wall of the installation slot 201d; the guide assembly 203 includes a support frame 203a fixedly connected to the installation box 201a, and a lifting plate 203b is slidably connected to the inner wall of the support frame 203a, and a vertical opening 203c penetrating the support frame 203a is provided on the lifting plate 203b, and the insert block 202c penetrates the vertical opening 203c, and the insert block 202c is fixedly connected to the lifting plate 203b, and the lifting plate 203b is slidably connected to the support frame 203a, and the lifting plate 203b is elastically connected to the support frame 203a through a second spring 203d.

[0036] It should be noted that the initial positions of the first mounting opening 202a and the second mounting opening 202b are misaligned, so that the plug 202c cannot penetrate the second mounting opening 202b, and the length of the mounting groove 201d is greater than the sum of the widths of the plug 202c and the mounting box 201a, so that the plug 202c and the mounting groove 201d will not be stuck.

[0037] When in use, when the first flange 102 and the second flange 103 need to be fixed, the installation box 201a on the first flange 102 only needs to be inserted into the installation groove 201d on the second flange 103. At this time, the first installation port 202a and the second installation port 202b are misaligned, and the insert block 202c cannot move to the lower side of the installation box 201a. The first spring 201c is in a compressed state. When the slider 201b on the installation box 201a abuts against the inner wall of the installation groove 201d, the valve continues to be pushed. The main body 101 causes the slider 201b to move toward the installation box 201a, so that the first installation port 202a is opposite to the second installation port 202b. At this time, the plug block 202c is opposite to the slot 202d, and under the action of the first spring 201c, the plug block 202c penetrates the first installation port 202a and the second installation port 202b and enters the slot 202d. At this time, the first flange 102 and the second flange 103 cannot be separated, thereby realizing the connection between the valve main body 101 and the waste heat recovery pipeline 104.

[0038] In summary, when it is necessary to connect the valve body 101 and the waste heat recovery pipeline 104, it is only necessary to insert the installation box 201a on the first flange 102 on the valve body 101 into the installation groove 201d on the second flange 103, so as to achieve the fixation between the first flange 102 and the second flange 103 and realize the connection between the valve body 101 and the waste heat recovery pipeline 104.

[0039] Example 2

[0040] Reference Figure 1 to Figure 6, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a transmission assembly 204 for a valve for a waste heat recovery device, which solves the problem of how to disassemble the valve body 101 and the waste heat recovery pipeline 104. It includes a transmission assembly 204, including a plurality of third mounting ports 204a arranged on the first flange 102, and the plurality of third mounting ports 204a are all provided with a circular port 204b penetrating the first flange 102, and an L-shaped rod 204c is slidably connected in the third mounting port 204a; a reset assembly 205 includes a circular ring 205a fixedly connected to the first flange 102, and the circular ring 205a is provided with a T-shaped groove 205b, and the T-shaped groove 205b is provided with a T-shaped ring 205 c, a rotating ring 205d is fixedly connected to the T-shaped ring 205c, a first arc groove 205e is provided on the rotating ring 205d, a second arc groove 205f is provided on the first arc groove 205e, a third arc groove 205g connected to the first arc groove 205e is provided on the second arc groove 205f, a guide rod 205h matched with the first arc groove 205e is provided on the L-shaped rod 204c, an extension groove 205i is provided in the third arc groove 205g, a transmission shaft 205j is rotatably connected in the extension groove 205i, a baffle 205k is fixedly connected to the transmission shaft 205j, a torsion spring is provided on the transmission shaft 205j, and the baffle 205k is away from the side wall of the first arc groove 205e and abuts against the inner wall of the extension groove 205i.

[0041] Specifically, the upper end of the L-shaped rod 204c passes through the circular opening 204b and extends to the outside of the first flange 102. The T-slot 205b cooperates with the T-ring 205c to prevent the rotating ring 205d from being separated from the circular ring 205a, thereby ensuring the stability of the rotating ring 205d during rotation. The setting of the baffle 205k can limit the guide rod 205h to prevent the guide rod 205h from returning from the first arc groove 205e to the third arc groove 205g. Since the baffle 205k is away from the side wall of the first arc groove 205e and abuts against the inner wall of the epitaxial groove 205i, the baffle 205k can only deflect toward the first arc groove 205e and cannot deflect toward the third arc groove 205g. Damping is provided between the T-slot 205b and the T-ring 205c here to prevent the rotating ring 205d from self-rotating.

[0042] During use, when the guide rod 205h is in the first arc groove 205e, due to the obstruction of the baffle 205k, the guide rod 205h cannot move downward into the third arc groove 205g. At this time, the guide rod 205h cannot drop, and the L-shaped rod 204c cannot drop. Even if the first mounting port 202a is directly opposite to the second mounting port 202b, the plug block 202c cannot move. When it is necessary to fix the first flange 102 and the second flange 103, it is only necessary to rotate the rotating ring 205d counterclockwise (from the right side, the same below) to move the guide rod 205h to the connection between the first arc groove 205e and the second arc groove 205f. When the first mounting port 202a is directly opposite to the second mounting port 202b, the guide rod 205h can move in the second arc groove 205f, and the plug block 202c can be inserted through transmission. In the slot 202d, when the insert block 202c is inserted into the slot 202d, the guide rod 205h moves to the connection between the second arc groove 205f and the third arc groove 205g. When the first flange 102 and the second flange 103 need to be disassembled, it only needs to be rotated clockwise. At this time, the guide rod 205h slides in the third arc groove 205g. Under the guidance of the third arc groove 205g, the guide rod 205h moves upward. At this time, the baffle 205k can be deflected toward the first arc groove 205e and will not block the guide rod 205h. During the upward process of the guide rod 205h, it can drive the L-shaped rod 204c to move, so that the insert block 202c moves upward and disengages from the slot 202d. At this time, the first flange 102 and the second flange 103 can be separated, and the valve body 101 and the waste heat recovery pipe 104 can be disassembled.

[0043] In summary, when it is necessary to disassemble the valve body 101 and the waste heat recovery pipe 104, it is only necessary to turn the rotating ring 205d on the first flange 102 to make the guide rod 205h rise along the third arc groove 205g, and the plug block 202c is separated from the slot 202d through transmission. At this time, the installation box 201a can be pulled out to realize the disassembly between the first flange 102 and the second flange 103, and the disassembly between the valve body 101 and the waste heat recovery pipe 104.

[0044] Example 3

[0045] Reference Figure 1 to Figure 10, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a sealing component 300 for a valve for a waste heat recovery device, which solves the problem of how to automatically seal the waste heat recovery pipeline 104 after the valve body 101 is separated from the waste heat recovery pipeline 104. It includes a sealing component 301 including a plurality of receiving grooves 301a arranged on the second flange 103, and the plurality of receiving grooves 301a are rotatably connected to a rotating shaft 301b, and a sealing plate 301c is fixedly connected to the rotating shaft 301b. A rubber pad 301d is provided at one end of the plate 301c close to the accommodating groove 301a, and multiple sealing plates 301c are combined into a disc with a diameter equal to the inner diameter of the waste heat recovery pipe 104. A water guide ring 301e that cooperates with the sealing plate 301c is fixedly connected in the waste heat recovery pipe 104; the rotating component 302 includes a cavity 302a arranged in the second flange plate 103, the rotating shaft 301b extends into the cavity 302a and is rotatably connected to the inner wall of the cavity 302a, and a fourth arc groove 302b is provided on the side wall of the rotating shaft 301b.

[0046] Specifically, the rubber pad 301d is configured so that when the sealing plate 301c rotates, the rubber pad 301d can be deformed when it abuts against the inner wall of the receiving groove 301a, thereby avoiding the sealing plate 301c and the inner wall of the receiving groove 301a from getting stuck. The water guide ring 301e is configured to guide the water flow, thereby avoiding the sealing plate 301c from being reset under the action of liquid or gas after the sealing plate 301c is unfolded.

[0047] Furthermore, the toggle assembly 303 includes a transverse groove 303a arranged on the inner wall of the slot 202d, a movable plate 303b is slidably connected in the transverse groove 303a, a guide opening 303c connected to the transverse groove 303a is provided on the cavity 302a, and a guide rod 303d that cooperates with the fourth arc groove 302b is fixedly connected to the movable plate 303b; the movable assembly 304 includes a connecting column 304a fixedly connected to the movable plate 303b, a wedge block 304b is fixedly connected to the connecting column 304a, and the movable plate 303b is elastically connected to the inner wall of the transverse groove 303a through a third spring 304c.

[0048] It should be noted that the guide rod 205h cooperates with the fourth arc groove 302b to drive the rotating shaft 301b to rotate, thereby driving the sealing plate 301c to rotate, so that the waste heat recovery pipe 104 is opened, and the bevel of the wedge block 304b cooperates with the plug block 202c to avoid the plug block 202c from getting stuck downward between the wedge block 304b.

[0049] When in use, in the initial state, the plurality of sealing plates 301c are combined into a disc with a diameter equal to the inner diameter of the waste heat recovery pipe 104, so as to close the waste heat recovery pipe 104. At this time, the gas or liquid in the waste heat recovery pipe 104 does not flow out, and due to the pressure problem, the sealing plate 301c is compressed, so that the sealing plate 301c is not easy to be opened, and the greater the pressure, the less likely the sealing plate 301c is to loosen, so as to ensure the stability of the seal. When the valve body 101 is connected to the waste heat recovery pipe 104, when the plug 202c is inserted into the card slot 202d, it can push the wedge block 304b to move, drive the connecting column 304a to move, and make the moving plate 303b move. The third spring 304c is compressed, and when the moving plate 303b moves, it drives the guide rod 303 d movement, the guide rod 303d cooperates with the fourth arc groove 302b to drive the rotating shaft 301b to rotate, so that the sealing plate 301c is opened. After the sealing plate 301c is opened, the sealing plate 301c is close to the inner wall of the waste heat recovery pipe 104, and the guide ring can guide the water flow or air flow to avoid the sealing plate 301c automatically resetting under the action of liquid or gas after the sealing plate 301c is unfolded. The elasticity of the second spring 203d here is greater than the elasticity of the third spring 304c, thereby avoiding the automatic resetting of the moving plate 303b. After the plug 202c is pulled out, the moving plate 303b is reset under the action of the third spring 304c, and the sealing plate 301c is reset through transmission to close the waste heat recovery pipe 104 again.

[0050] In summary, by setting the closing component 300, the waste heat recovery pipe 104 can be automatically closed after the valve body 101 is separated from the waste heat recovery pipe 104, so there is no need to close the valve on the waste heat recovery pipe 104, and the valve body 101 can also be disassembled, which is more convenient to use.
