[0044] Example 1

[0045] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, proposes

[0046] A quick disassembly and assembly device for valve series pressure testing is used for synchronous pressure testing of multiple valve bodies 1 connected in series, including a support seat 2, wherein the support seat 2 has multiple support seats 2, and the multiple support seats 2 are distributed at intervals; there are multiple sliding seats 3, two sliding seats 3 form a group, and a group of sliding seats 3 are relatively slidably arranged on the support seat 2; a clamping piece 4 is arranged on the sliding seat 3, and the clamping piece 4 is used to clamp two adjacent valve bodies 1; a driving mechanism 5 is connected to the clamping piece 4, and the driving mechanism 5 is used to control the clamping piece 4 to tighten or loosen the two adjacent valve bodies 1.

[0047] In this embodiment, in order to solve the problem in the related art that it is inconvenient to perform synchronous pressure testing on multiple valves, the two adjacent valve bodies 1 are tightened by the clamping members 4, so that the multiple valve bodies 1 are connected in series in sequence. The two clamping members 4 respectively clamp the upper and lower sides of the two adjacent valve bodies 1, which has better sealing performance and avoids the effect of the pressure testing of the valve body 1 due to air leakage at the connection. The distance between the two clamping members 4 can be changed by sliding a group of sliding seats 3, so that the clamping members 4 can connect valve bodies 1 of multiple different specifications in series, thereby improving the versatility of the quick disassembly and assembly device and further reducing the cost.

[0048] Specifically, when performing pressure testing on multiple valve bodies 1, firstly, multiple support seats 2 are arranged in sequence according to the specifications of the valve bodies 1, and then the distance between each group of sliding seats 3 is adjusted according to the size of the valve bodies 1, so that the clamping member 4 can clamp and fix two adjacent valve bodies 1. After the valve bodies 1 are connected by the clamping member 4, the two ends of the valve bodies 1 connected in series can be connected to the pressure testing device respectively, and multiple valve bodies 1 can be pressure tested synchronously at the same time, which is simple and convenient to operate and has higher pressure testing efficiency.

[0049] Furthermore, it also includes a first telescopic rod 6, which has multiple first telescopic rods 6, and the two ends of the first telescopic rod 6 are respectively arranged on the support seat 2 and the sliding seat 3; the elastic member 7 is sleeved on the first telescopic rod 6, and the two ends of the elastic member 7 are respectively connected to the support seat 2 and the sliding seat 3, and the sliding seat 3 is used to provide a force for the sliding seat 3 to approach the support seat 2; the limit plate 8 is slidably arranged on the support seat 2, and after the limit plate 8 slides, it is used to drive the sliding seat 3 away from the support seat 2.

[0050] In this embodiment, a first telescopic rod 6 and an elastic member 7 are connected between the sliding seat 3 and the support seat 2. A group of sliding seats 3 can be brought closer to each other through a sliding limit plate 8, thereby adjusting the distance between the two clamping members 4 so that the clamping members 4 can clamp valve bodies 1 of different specifications. After the pressure test is completed, after the limit plate 8 is reset, the sliding seat 3 slides to the side close to the support seat 2 under the action of the elastic member 7 and resets. The first telescopic rod 6 can make the sliding process of the sliding seat 3 more stable and prevent the clamping member from shaking.

[0051] Furthermore, the sliding seat 3 has a guide groove 301 at one end close to the support seat 2, and the limiting plate 8 has a guide slope 801 at one end close to the sliding seat 3, and the guide slope 801 abuts against the guide groove 301, and also includes a first telescopic member 9, which is arranged on the support seat 2 and is used to drive the limiting plate 8 to slide.

[0052] In this embodiment, the first telescopic member 9 drives the limit plate 8 to slide, and then the guide slope 801 drives the sliding seat 3 to slide, so that the clamping member 4 can clamp the two adjacent valve bodies 1. During the sliding of the limit plate 8, the guide slope 801 slides along the guide groove 301. The setting of the guide groove 301 makes the connection between the sliding seat 3 and the limit plate 8 more stable. The first telescopic member 9 is set on one side of the support seat 2. The first telescopic member 9 and the limit plate 8 drive the sliding seat 3 to slide. Compared with the telescopic member directly set at one end of the sliding seat 3 to drive the sliding seat 3 to slide, the arrangement is more reasonable, making the size of the entire quick disassembly and assembly device more symmetrical and convenient for storage.

[0053] Furthermore, two first telescopic rods 6 form a group, and a group of first telescopic rods 6 is symmetrically distributed on both sides of the sliding seat 3 .

[0054] Furthermore, the driving mechanism 5 includes a hydraulic pump 501 ; a hydraulic synchronizer 502 is connected to the hydraulic pump 501 , and the hydraulic synchronizer 502 is connected to the clamping member 4 .

[0055] In this embodiment, through the cooperation of the hydraulic pump 501 and the hydraulic synchronizer 502, multiple clamping members 4 can be controlled to be clamped synchronously, thereby improving the efficiency when multiple valve bodies 1 are connected in series, making the pressure test process more efficient.

[0056] Furthermore, it also includes a blind plate 10, which is arranged at one end of a plurality of valve bodies 1 connected in series, and is used to seal the valve bodies 1 located on both sides; a pressure gauge 11 is arranged on the blind plate 10, and the pressure gauge 11 is used to display the pressure inside the valve body 1.

[0057] In this embodiment, one end of the series-connected valve body 1 connected to the outside is blocked by a blind plate 10, and the other end of the series-connected valve body 1 is connected to a pressure test pump. A relatively closed space is formed between the pressure test pump, the series-connected valve body 1 and the blind plate 10. The pressure gauge 11 on the blind plate 10 can display the pressure inside the valve body 1 in real time, which is convenient for observing the results of the pressure test.

[0058] Furthermore, the clamping member 4 includes a support frame 401, which is arranged on the sliding seat 3; there are two second telescopic rods 402, which are arranged on the support frame 401, and the output ends of the two second telescopic rods 402 are facing the two sides of the support frame 401, and the hydraulic synchronizer 502 is used to control the extension and retraction of the second telescopic rod 402; the pressure plate 403 is arranged on the second telescopic rod 402, and the second telescopic member is used to drive the pressure plate 403 to move closer to or away from the valve body 1.

[0059] In this embodiment, the two second telescopic rods 402 are arranged opposite to each other and connected to the hydraulic synchronizer 502. The hydraulic pump 501 and the hydraulic synchronizer 502 can drive the second telescopic rods 402 to extend and retract, thereby making the two pressure plates 403 move closer to or farther from each other, thereby clamping the two adjacent pump bodies or canceling the clamping of the two valve bodies 1 after the pressure test is completed. The clamping member 4 conveniently connects the two valve bodies 1 together, so that the pressure test can be carried out quickly.

[0060] Furthermore, the pressing plate 403 is arc-shaped.

[0061] In this embodiment, the arc-shaped pressing plate 403 can better fit the valve body 1 , so that the sealing between the two valve bodies 1 is better.

[0062] Furthermore, it also includes a supporting leg 12 , and there are multiple supporting legs 12 , and the multiple supporting legs 12 are arranged on the supporting seat 2 .

[0063] In this embodiment, the support base 2 is supported by the support legs 12, and space can be reserved between the support base 2 and the ground. A through groove is opened on the support base 2, which can play a guiding role when the limit plate 8 slides. The setting of the support legs 12 can avoid friction between the limit plate 8 and the ground when sliding.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
