[0002] The ball valve is an important fluid control device, and its core component is a ball with a through hole. The opening and closing of the pipeline are realized by rotating the ball. The ball valve has simple structure, convenient operation, small fluid resistance and good sealing performance, and is widely used in petroleum, chemical industry, water treatment, natural gas and other fields.

[0003] The assembling of the ball valve in the prior art needs to ensure that the valve body flange is correctly sleeved on the pipeline, and the connecting end is welded or fastened to the pipeline. Then, the components such as bolts, sleeves and nuts are sleeved on the valve body flange according to the design requirements, and space is reserved for subsequent installation of the valve body. Then, the valve body is installed between the two connecting ends, and the valve ball is ensured to be in the open position. Then, the remaining bolts, sleeves and nuts are installed, and the valve is adjusted to the required direction, and the nuts are tightened according to the specified torque value to ensure stability. The closed ball valve is sent to the detection station for sealing detection.

[0004] For the related technology in the above, the valve ball in the valve body may be disturbed during the installation of the valve body and the adjustment of the valve, which may cause the displacement of the valve ball, thereby affecting the accuracy of the ball valve structure. And only the closed ball valve is detected, which may not be comprehensive enough. SUMMARY

[0036] Refer to Figure 2 and Figure 3The first driving assembly 5 comprises a driving motor 51, a cylinder 52, a rotating ring 53 and a clamping ring 54. The fixed end of the cylinder 52 is arranged on the mounting frame 1, the telescopic end of the cylinder 52 is connected to the end of the first moving column 3 away from the second moving column 4, the clamping ring 54 is arranged on the telescopic end of the cylinder 52, the rotating ring 53 is arranged on the end of the first moving column 3 away from the second moving column 4, the rotating ring 53 is arranged in the clamping ring 54 in a rotating manner, the driving motor 51 is arranged on the mounting frame 1, and the output end of the driving motor 51 is connected to the end of the first moving column 3 away from the second moving column 4.

[0038] Referring to Figure 2 and Figure 4 The detection device 6 comprises a first sealing mechanism 61 and a second sealing mechanism.

When the clamping block 612 is located in the clamping groove 614, the first moving column 3 and the sealing head 611 are clamped in the horizontal direction. The first sealing assembly 613 is arranged on the first moving column 3 to improve the sealing degree between the first moving column 3 and the inner wall of the flow channel of the first assembly part 21. The second sealing assembly is arranged on the sealing head 611 to improve the sealing degree between the sealing head 611 and the inner wall of the flow channel of the ball center 23.

A through hole is formed in the bottom of the annular groove. The annular groove and the installation groove are communicated through the through hole. The air bag 6131 comprises an annular part 6133 and a protruding part 6134. The annular part 6133 of the air bag 6131 is sleeved on the first moving column 3 and located in the annular groove.

The third driving assembly 7 is arranged on the first moving column 3 and used to drive the adjusting disc 6132 to rotate. The second sealing assembly is arranged in the same way as the first sealing assembly 613.

[0041] The third driving assembly 7 drives the adjusting disc 6132 to rotate, so that the wave-shaped annular outer side of the adjusting disc 6132 abuts against the protruding part 6134 of the air bag 6131, realizing the extrusion of the protruding part 6134 of the air bag 6131, further improving the pressure in the air bag 6131, and making the air bag 6131 and the flow channel fit more closely, thereby improving the sealing between the first moving column 3 and the flow channel, providing more perfect detection conditions for subsequent sealing detection, thereby further improving the accuracy of the subsequent sealing detection result.

The end of the mounting column 71 close to the passive disc 74 is provided with a driving groove. The driving structure 75 is used to drive the passive disc 74 to rotate after the cubic driving block 77 completely enters the driving groove.

[0043] After the first moving column 3 and the second moving column 4 are separated from the sealing head 611 at the ends, the first moving column 3 and the second moving column 4 abut against the sealing head 611 respectively. After the cubic driving block 77 on the passive disc 74 completely enters the driving groove, the passive disc 74 rotates under the action of the driving structure 75. Since the ratchet wheel 72 is mounted on the mounting column 71 and the driving groove is arranged on the mounting column 71, the ratchet wheel 72 and the adjusting disc 6132 can be driven to rotate. At this time, the ratchet wheel 72 and the pawl 73 are not engaged, the wavy annular outer side of the adjusting disc 6132 abuts against the protruding part 6134 of the air bag 6131, the protruding part 6134 of the air bag 6131 is extruded, the ratchet wheel 72 has a reverse rotation tendency after the adjusting disc 6132 rotates, the ratchet wheel 72 and the pawl 73 are engaged with each other to lock, the adjusting disc 6132 is kept stationary, the mounting column 71 is rotated by ninety degrees by the cubic driving block 77 at this time, the first moving column 3 and the second moving column 4 are separated after rotating and abutting against the sealing head 611, the driving structure 75 makes the cubic driving block 77 completely separate from the driving groove to reset, and the above operation is repeated to rotate the adjusting plate by ninety degrees again, so that the wavy annular outer side of the adjusting disc 6132 does not abut against the protruding part 6134 of the air bag 6131, and the protruding part 6134 of the air bag 6131 is not extruded.

[0044] Referring to Figure 2 and Figure 4 The driving structure 75 comprises a driving disc 751 and a torsion spring 752. The driving disc 751 is fixedly arranged in the rotating groove. The torsion spring 752 is arranged in the rotating groove and connected with the groove bottom at one end and connected with the passive disc 74 at the other end. The ends of the passive disc 74 and the driving disc 751 close to each other are arranged in a wavy shape and staggered with each other.

[0045] The end of the passive disc 74 and the active disc 751 close to each other is arranged in a wave shape and staggered with each other. When the passive disc 74 and the active disc 751 abut, the cubic driving block 77 is completely in the driving groove. Since the active disc 751 is fixedly installed, the relative rotation between the passive disc 74 and the active disc 751 can be realized and the wave-shaped edges are engaged, so as to realize the rotation of the cubic driving block 77.

[0046] With reference to Figure 2 And Figure 3 The air inlet and outlet mechanism 8 comprises a first air inlet and outlet structure 81 and a second air inlet and outlet structure. The first air inlet and outlet structure 81 comprises a first air outlet disc 811 and a colored gas storage box 812. The first air outlet disc 811 is arranged on the mounting frame 1. An air outlet port 813 and a colored gas inlet port are arranged on the air outlet disc. The length of the air outlet port 813 is arranged according to the moving distance of the first moving column 3. A gas passage is arranged in the first moving column 3. The gas passage is communicated with a mounting groove. The mounting groove is communicated with the end of the first moving column 3 close to the second moving column 4. When the first moving column 3 is fixedly connected with the sealing head 611 in the horizontal direction, the air outlet port 813 is communicated with the gas passage. The colored gas inlet port is not communicated with the gas passage. When the first moving column 3 is separated from the sealing head 611, the colored gas inlet port is communicated with the gas passage. The air outlet port 813 is not communicated with the gas passage. The colored gas storage box 812 is arranged at the end of the colored gas inlet port away from the gas passage. The second air inlet and outlet structure is arranged on the second moving column 4 and arranged with the first air inlet and outlet structure 81.

[0047] When the first moving column 3 and the second moving column 4 move close to the flow channel, the pressure in the flow channel increases. The first moving column 3 and the second moving column 4 are not separated from the sealing head 611. The first moving column 3 and the second moving column 4 do not rotate. At this time, the air outlet port 813 is communicated with the gas passage. The colored gas inlet port is not communicated with the gas passage. Part of the air in the ball valve 2 is discharged through the air outlet port 813. After the first moving column 3 and the second moving column 4 are separated from the sealing head 611 and rotated, the first moving column 3 and the second moving column 4 rotate. After the first moving column 3 and the second moving column 4 move away from each other, the pressure in the flow channel decreases. The colored gas inlet port is communicated with the gas passage. The air outlet port 813 is not communicated with the gas passage. The colored gas in the colored gas storage box 812 enters the ball valve 2. Then the first moving column 3 and the second moving column 4 are close to each other to pressurize the inside of the ball valve 2. Thus, according to the colored gas leakage, the sealing detection of each connection of the ball valve 2 can be performed when the ball valve 2 is opened. Thus, the control of the quality of the ball valve 2 is further improved, and the quality of the finished ball valve 2 is improved.

[0048] The implementation principle of the ball valve automatic assembly and detection integrated device in the embodiment of the application is as follows:

[0049] When it is needed to align the flow channels in the first assembly part 21, the second assembly part 22 and the ball core 23, the air cylinder 52 is started, and since the clamping ring 54 at the end of the air cylinder 52 is connected with the rotating ring 53, the telescopic end of the air cylinder 52 is elongated to drive the first moving column 3 to move away from the air cylinder 52, and the second driving assembly is arranged with the first driving assembly 5, so that the first moving column 3 and the second moving column 4 can be close to each other, and since the first moving column 3 and the second moving column 4 are symmetrically arranged, the flow channels in the first assembly part 21, the second assembly part 22 and the ball core 23 can be aligned;

[0050] When it is needed to detect the sealing performance of the opened ball valve 2, the first moving column 3 and the second moving column 4 are moved close to each other in the flow channel, at this time, the air outlet 813 is communicated with the gas channel, the colored gas inlet is not communicated with the gas channel, and part of the air in the ball valve 2 is discharged through the air outlet 813, after the first moving column 3 and the second moving column 4 are separated from the sealing head 611, the first moving column 3 and the second moving column 4 are moved away from each other, the pressure in the flow channel is reduced, the colored gas inlet is communicated with the gas channel, the air outlet 813 is not communicated with the gas channel, the colored gas in the colored gas storage tank 812 enters the ball valve 2, and the first moving column 3 and the second moving column 4 are moved close to each other to pressurize the inside of the ball valve 2, so that whether the colored gas leaks or not can be detected when the ball valve 2 is opened, and the sealing performance of each connection of the ball valve 2 can be detected, so that the quality of the ball valve 2 is further controlled, and the quality of the finished ball valve 2 is improved.
