[0026] In this embodiment, the first plate body 11 can be fixedly connected to the first valve body 2, such as the suction valve of a cone valve type industrial pump, through the first through hole 111, and the second plate body 12 can be fixedly connected to the second valve body 3, such as the pressure valve of a cone valve type industrial pump, through the second through hole 121. Then, the first valve body 2 and the second valve body 3 can be separated or connected by separating or connecting the first plate body 11 and the second plate body 12. In order to quickly release or lock the first plate body 11 and the second plate body 12, a first bracket 112 is provided on one side of the first plate body 11, and a second bracket 122 is provided on one side of the second plate body 12. The first end of the movable rod 13 is rotatably connected to the first bracket 112, and after the first plate body 11 and the second plate body 12 are respectively installed on the first valve body 2 and the second valve body 3, the second end of the movable rod 13 can be rotated around the first end of the movable rod 13 relative to the first bracket 112 to the position of the first bracket 112, and then the locking piece 14 connected to the second end of the movable rod 13 abuts against the second bracket 122 to fix the movable rod 13 and limit the rotation or loosening of the movable rod 13, thereby locking and connecting the first plate body 11 and the second plate body 12. In this way, the first valve body 2 and the second valve body 3 respectively fixedly connected to the first plate body 11 and the second plate body 12 are also locked and connected.

[0027] The quick-release locking device 1 provided in the embodiment of the present application comprises a first plate body 11, a second plate body 12, a movable rod 13 and a locking member 14, wherein the first plate body 11 is provided with a first through hole 111 penetrating both sides and a first bracket 112 is provided on one side, and the second plate body 12 is provided with a second through hole 121 penetrating both sides and a second bracket 122 is provided on one side; and the first end of the movable rod 13 is rotatably connected to the first bracket 112; the locking member 14 is connected to the second end of the movable rod 13, and when the second end of the movable rod 13 is rotated relative to the first bracket 112 to the second bracket 122, the locking member 14 can abut against the second bracket 122. After the first plate body 11 and the second plate body 12 of the quick-release locking device 1 are respectively installed on the valve body of the industrial pump, the disassembly, separation and locking connection operations of the first plate body 11 and the second plate body 12 are convenient during use, thereby effectively improving the convenience of disassembly and assembly of the valve body of the industrial pump.

[0028] Since the movable rod 13 is rotatably connected to the first bracket 112, if the strength of the rotatable connection structure is insufficient or the rotatable operation is inconvenient, it will affect the safety and convenience of using the quick-release locking device 1. Therefore, optionally, in one embodiment of the present application, the first bracket 112 includes a first support plate 1121 and a second support plate 1122 arranged in parallel, and a first through groove is formed between the first support plate 1121 and the second support plate 1122. The first end of the movable rod 13 is located in the first through groove, the first support plate 1121 is provided with a first through hole, the second support plate 1122 is provided with a second through hole, the first end of the movable rod 13 is provided with a third through hole, and a pin shaft 15 is passed through the first through hole, the third through hole and the second through hole.

[0029] See also Figure 2 , Figure 3 The first support plate 1121 and the second support plate 1122 arranged in parallel can provide the movable rod 13 with the required bearing strength. At the same time, through holes are respectively provided in the first support plate 1121, the second support plate 1122 and the first end of the movable rod 13 to penetrate the pin 15 to realize the rotation connection between the movable rod 13 and the first bracket 112. The rotation connection method is safe and reliable and suitable for use under slurry conveying conditions; the first through groove formed between the first support plate 1121 and the second support plate 1122 can provide an accommodating space for the rotation of the movable rod 13. At the same time, the through groove structure is also easy to clean debris, and is convenient for use and maintenance.

[0030] In order to facilitate component processing, the same structural features can be designed for the first plate body 11 and the second plate body 12 to improve processing efficiency and interchangeability of components. Therefore, optionally, in one embodiment of the present application, the second bracket 122 includes a third support plate 1221 and a fourth support plate 1222 arranged in parallel, and a second through groove is formed between the third support plate 1221 and the fourth support plate 1222; the first through groove and the second through groove form a string groove when they are aligned along the through direction of the groove, and the movable rod 13 can rotate around the pin shaft 15 and be accommodated in the string groove.

[0031] The first plate 11 and the second plate 12 may have the same structural shape, the second bracket 122 sets the third support plate 1221 and the fourth support plate 1222 in parallel, and the second through groove is formed between the third support plate 1221 and the fourth support plate 1222, so that the second plate 12 and the first plate 11 can use the same processing station, and further, the third support plate 1221 and the fourth support plate 1222 of the second bracket 122 can be provided with hole structures such as the first perforation and the second perforation respectively, so as to improve the interchangeability of the first plate 11 and the second plate 12 when in use. In this embodiment, the first through groove can provide a accommodating space for the portion close to the first end of the movable rod 13, and the second through groove can provide a accommodating space for the portion close to the second end of the movable rod 13, so that the first plate 11 and the second plate 12 can form a series groove when the first through groove and the second through groove are aligned along the through direction of the groove according to the designed installation position, and provide a accommodating space for the movable rod 13 to fix the first plate 11 and the second plate 12.

[0032] When the movable rod 13 rotates, in order to prevent the pin 15 from falling off, optionally, in one embodiment of the present application, the first end of the pin 15 is provided with a disc-shaped structure, and the outer diameter of the disc-shaped structure is larger than the inner diameter of the first perforation and / or the second perforation. It can be understood that the provision of a disc-shaped structure having an outer diameter larger than the inner diameter of the first perforation or the second perforation at the first end of the pin 15 can limit the movement of the pin 15 axially toward the second end.

[0033] At the same time, a limiting structure can be further configured for the second end of the pin shaft 15. Therefore, optionally, in one embodiment of the present application, an annular groove is circumferentially provided on the outer surface of the second end of the pin shaft 15, and a clamp is provided in the annular groove.

[0034] The clamp embedded in the annular groove can be a standard part such as a retaining spring. It can be understood that due to the obstruction of the first bracket 112, the clamp can limit the axial movement of the pin 15 toward the first end. Therefore, the disc structure and the clamp arranged at both ends of the pin 15 form an axial limit for the pin 15 to prevent the pin 15 from falling off during use, thereby improving the safety and reliability of the rotational connection between the movable rod 13 and the first bracket 112.

[0035] In order to further improve the convenience of use and component versatility of the quick-release locking device 1, optionally, in an embodiment of the present application, the second end of the movable rod 13 is provided with a thread, and the locking member 14 includes a locking nut 141 and a gasket 142; the locking nut 141 is threadedly connected to the second end of the movable rod 13, and when the second end of the movable rod 13 is rotated relative to the first bracket 112 to the second bracket 122, the gasket 142 mounted on the movable rod 13 can be abutted against the second bracket 122.

[0036] The second end of the movable rod 13 is specifically configured as a threaded connection, so that the movable rod 13 can directly use standard parts such as a swing bolt, thereby reducing design costs and processing costs. At the same time, the locking member 14 is correspondingly configured as a locking nut 141 and a gasket 142, which is convenient for selecting the locking nut 141 and the gasket 142 according to the swing bolt, so that the locking member 14 can also be correspondingly selected as a standard part, further reducing the use cost. When the second end of the movable rod 13 rotates relative to the first bracket 112 to the second bracket 122, the gasket 142 sleeved on the movable rod 13 is abutted against the second bracket 122 by tightening the locking nut 141, thereby achieving the fixing and anti-loosening function of the movable rod 13.

[0037] Optionally, in one embodiment of the present application, the quick-release locking device 1 further includes a connecting member 16, and the first through hole 111 and the second through hole 121 are respectively provided with the connecting member 16. The connecting member 16 may specifically be a standard part such as a bolt and a locking gasket 142, and the first valve body 2 and the second valve body 3 are respectively provided with matching bolt holes, so that the first plate body 11 and the second plate body 12 are respectively fixedly connected to the first valve body 2 and the second valve body 3 by inserting the connecting member 16 in the first through hole 111 and the second through hole 121, and a plurality of first through holes 111 and second through holes 121 may be respectively provided according to the structural dimensions of the first plate body 11 and the second plate body 12 to meet the connection strength.

[0038] In order to further improve the connection reliability of the quick-release locking device 1, optionally, in one embodiment of the present application, more than two first brackets 112 are provided on the first plate body 11, and a second bracket 122 matched with each first bracket 112 is provided on the second plate body 12, and each pair of the first bracket 112 and the second bracket 122 is provided with a movable rod 13 and a locking member 14. It can be understood that when multiple pairs of first brackets 112 and second brackets 122 are provided on the first plate body 11 and the second plate body 12, a more stable locking connection effect can be formed, so that the first valve body 2 and the second valve body 3 fixedly connected to the first plate body 11 and the second plate body 12 respectively have better connection strength and sealing effect.

[0039] In the second aspect, an embodiment of the present application further provides a quick-release valve, comprising: a first valve body 2, a second valve body 3 and a quick-release locking device 1, wherein one end of the first valve body 2 is provided with more than two first fixing portions 21, and one end of the second valve body 3 is provided with a second fixing portion 31 matched with each first fixing portion 21; the quick-release locking device 1 is any one of the quick-release locking devices 1 described above; wherein each pair of first fixing portions 21 and second fixing portions 31 is provided with a quick-release locking device 1, the first fixing portion 21 is fixedly connected to the first plate body 11 of the quick-release locking device 1, and the second fixing portion 31 is fixedly connected to the second plate body 12 of the quick-release locking device 1.

One end of the first valve body 2 is connected to one end of the second valve body 3. At the end where the first valve body 2 is connected to the second valve body 3, more than two first fixing parts 21 are provided. For example, two first fixing parts 21 can be symmetrically provided at the end of the first valve body 2. Similarly, at the corresponding position of the end where the second valve body 3 is connected to the first valve body 2, a second fixing part 31 matched with the first fixing part 21 is provided.

The first fixing part 21 can be fixedly connected to the first plate body 11 of the quick-release locking device 1, and the second fixing part 31 can be fixedly connected to the second plate body 12 of the quick-release locking device 1. In this way, when the first valve body 2 and the second valve body 3 are docked at a preset position, After the first and second fixing parts 21 and 31 are positioned, the movable rod 13 of the quick-release locking device 1 configured for each pair of the first fixing parts 21 and the second fixing parts 31 can be rotated, and when the second end of the movable rod 13 is rotated to the corresponding preset position of the second bracket 122, the locking piece 14 connected to the second end of the movable rod 13 is abutted against the second bracket 122 to limit the rotation or loosening of the movable rod 13, so as to lock and connect the first plate body 11 and the second plate body 12, so that the pair of first fixing parts 21 and second fixing parts 31 respectively fixedly connected to the first plate body 11 and the second plate body 12 are fixedly connected. After multiple pairs of first fixing parts 21 and second fixing parts 31 are fixedly connected, the first valve body 2 and the second valve body 3 are also locked and connected accordingly. In addition, the end portion where the first valve body 2 is connected to the second valve body 3 can be specifically configured with a docking sealing structure so that the first valve body 2 and the second valve body 3 meet the sealing requirements in the locked connection state. When it is necessary to separate the first valve body 2 and the second valve body 3, the locking piece 14 of the quick-release locking device 1 configured for each pair of first fixing parts 21 and second fixing parts 31 connected to the second end of the movable rod 13 is disengaged from the second bracket 122, so that the movable rod 13 can rotate and leave the second bracket 122, thereby separating the first plate body 11 and the second plate body 12, so that the pair of first fixing parts 21 and second fixing parts 31 respectively fixedly connected to the first plate body 11 and the second plate body 12 are released. After multiple pairs of first fixing parts 21 and second fixing parts 31 are released, the first valve body 2 and the second valve body 3 are also released accordingly, so that they can be disassembled and separated.

[0041] Thirdly, Figure 4As shown, an embodiment of the present application also provides a quick-release valve, comprising: a first valve body 2, a second valve body 3 and a quick-release locking device 1, wherein one end of the first valve body 2 is provided with a first connecting portion 22 and a first fixing portion 21, one end of the second valve body 3 is provided with a second connecting portion 32 and a second fixing portion 31, and the first connecting portion 22 and the second connecting portion 32 are rotatably connected; the quick-release locking device 1 is any of the quick-release locking devices 1 described above; wherein the first fixing portion 21 is fixedly connected to the first plate body 11 of the quick-release locking device 1, and the second fixing portion 31 is fixedly connected to the second plate body 12 of the quick-release locking device 1.

For example, the first connecting portion 22 can be a lug structure arranged on the side of one end where the first valve body 2 is connected to the second valve body 3. Similarly, the second connecting portion 32 can be another lug structure correspondingly arranged on the side of one end where the second valve body 3 is connected to the first valve body 2. A rotating shaft is passed through the above-mentioned lug structure so that the first valve body 2 and the second valve body 3 can rotate relative to each other around the rotating shaft.

[0043] In this embodiment, the first fixing portion 21 of the first valve body 2 can be fixedly connected to the first plate body 11 of the quick-release locking device 1 according to a preset installation position, and the second fixing portion 31 of the second valve body 3 can be fixedly connected to the second plate body 12 of the quick-release locking device 1. In this way, after the first valve body 2 and the second valve body 3 are relatively rotated around the rotating shaft to the docking position, the movable rod 13 of the quick-release locking device 1 can be rotated, and when the second end of the movable rod 13 is rotated to the corresponding preset position of the second bracket 122, the locking member 14 connected to the second end of the movable rod 13 is abutted against the second bracket 122 to limit the rotation or loosening of the movable rod 13, and the first plate body 11 and the second plate body 12 are locked and connected, so that the first valve body 2 and the second valve body 3 respectively fixedly connected to the first plate body 11 and the second plate body 12 are also locked and connected. In addition, the end portion where the first valve body 2 and the second valve body 3 are connected can be specifically configured with a docking sealing structure so that the first valve body 2 and the second valve body 3 meet the sealing requirements in the locked connection state. When it is necessary to separate the first valve body 2 and the second valve body 3, the locking piece 14 connected to the second end of the movable rod 13 is disengaged from the second bracket 122, so that the movable rod 13 can rotate and leave the second bracket 122, thereby separating the first plate body 11 and the second plate body 12, so that the first valve body 2 and the second valve body 3 respectively fixedly connected to the first plate body 11 and the second plate body 12 can rotate relative to each other around the rotating axis and open the inner cavity.
