Technical Field

[0001] The invention relates to the technical field of marine valve sealing detection, in particular to a production detection device applied to marine valves. Background Art

[0002] In order to control the pressure, flow and flow of fluid in ship pipelines, a large number of valve adjustment parts need to be installed inside the ship. The basic function of valves is to control the flow and direction of fluid pipelines, adjust the pressure and flow of the medium, and protect the normal operation of pipeline equipment.

[0003] The most critical factor for marine valves is sealing, and the internal dimensions and processing accuracy of the valve housing in the valve will have the most obvious impact on sealing. Therefore, it is necessary to test the sealing during the production process. The current testing method is just to measure the opening size to ensure its assembly accuracy, but it cannot simulate the load generated during use, resulting in limited test data, and it is impossible to perform high-precision inspection on the inside of the valve body. In addition, because manual inspection is mostly used, false inspection and missed inspection may occur. Summary of the invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4The device shown is used for the production and testing of marine valves, comprising a main frame 1 and a first electrically-controlled conveyor belt 2 installed on the main frame 1; an embedded electrically-controlled detection seat 3 is movably installed on the upper surface of the main frame 1 at the unloading end of the first electrically-controlled conveyor belt 2; a second electrically-controlled conveyor belt 4 is installed on the upper surface of the embedded electrically-controlled detection seat 3 at one side of the first electrically-controlled conveyor belt 2; a top mounting crossbeam 6 is fixedly installed on the upper surface of the main frame 1 at the periphery of the embedded electrically-controlled detection seat 3 through a lateral frame 5; a top mounting crossbeam 6 is provided at the lower end of the top mounting crossbeam 6; a top lifting machine 8 for controlling the top mounting crossbeam 7 is fixedly installed on the upper end of the top mounting crossbeam 6; two electrically-controlled telescopic detection covers 9 and two electrically-controlled telescopic limit frames 10 are symmetrically installed on the inner side of the lateral frame 5.

[0030] Working principle: The valve is translated to the second electrically controlled conveyor belt 4 through the first electrically controlled conveyor belt 2. At this time, the embedded electrically controlled detection seat 3 starts to rotate, and the electrically controlled telescopic limit frame 10 extends to the outside of the valve. At the same time, the second electrically controlled conveyor belt 4 starts to rotate independently in the opposite direction to control the rotation of the valve. This can shorten the valve adjustment time and improve the alignment efficiency of the valve and the electrically controlled telescopic detection cover 9 more quickly. After the detection is completed, the second electrically controlled conveyor belt 4 is controlled to rotate forward or flip at the same time according to the detection results to translate the valve to different stacking guide rails to facilitate the screening of unqualified valves.

[0031] In order to cooperate with the top assembly, a circular sinking groove 11 for installing the embedded electric control detection seat 3 is opened on the upper surface of the main frame 1, and an internal installation groove is opened on the inner bottom surface of the circular sinking groove 11.

[0032] In order to cooperate with the angle adjustment, the embedded electric control detection seat 3 includes an internal adjustment motor 31 fixed in the internal installation groove, an embedded adjustment disk 32 movably installed in the circular sinking groove 11 and a transmission gear 33 for transmission connection.

[0033] An arc-shaped adjustment tooth groove is provided on the lower surface of the embedded adjustment disk 32. The internal adjustment motor 31 is inserted into the arc-shaped adjustment tooth groove through the transmission gear 33 and is transmission-connected to the embedded adjustment disk 32. The transmission gear 33 is controlled to rotate by the internal adjustment motor 31, thereby driving the embedded adjustment disk 32 to rotate.

[0034] In order to coordinate translational conveying and rotational adjustment, the first electrically controlled conveyor belt 2 is composed of two first strip conveyor belts rotating synchronously and in the same direction, and the second electrically controlled conveyor belt 4 is composed of two second strip conveyor belts that can operate independently.

[0035] In order to cooperate with the top flow diversion, the protruding end of the lower end of the top elevator 8 passes through the top mounting beam 6 and is axially connected to the upper end connecting pipe of the top detection cover 7. An external connecting valve 12 with a built-in flow monitoring module is fixedly installed on the outer side of the top detection cover 7, and an external inlet pipe 13 is fixedly installed on the outer side of the external connecting valve 12.

[0036] In order to cooperate with lateral extrusion, the electrically controlled telescopic detection cover 9 includes a longitudinal guide rail 91 fixedly mounted on the outer wall of the lateral frame 5, an outer mounting seat 92 slidably assembled on the longitudinal guide rail 91, a first electrically controlled support rod 93 fixedly mounted on the outer mounting seat 92, a lateral extrusion sealing head 94 axially fixedly mounted on the protruding end of the first electrically controlled support rod 93, and a pressure sensor module 95 fixedly mounted on the end of the lateral extrusion sealing head 94.

[0037] The first electrically controlled support rod 93 controls the lateral extrusion sealing head 94 to be extruded inwardly by extending and is inserted into the opening outside the valve.

[0038] In order to cooperate with the extrusion and limiting on the outside when the valve rotates, the electric control telescopic limit frame 10 includes a second electric control support rod 101 fixedly installed on the outer side wall of the lateral frame 5 and an arc-shaped limit correction frame 102 axially fixed on the extended end of the second electric control support rod 101.

[0039] When the valve is translated from the first electrically-controlled conveyor belt 2 to the second electrically-controlled conveyor belt 4, the second electrically-controlled support rod 101 then extends and controls the arc-shaped limit correction frame 102 to be squeezed and translated toward the outer side of the valve. When the arc-shaped limit correction frame 102 moves to the outer side of the valve, the second electrically-controlled support rod 101 is closed, and then one of the two second conveyor belts starts to rotate in the opposite direction. The two horizontally-arranged second conveyor belts rotate in the opposite direction, which can control the valve to rotate on its own, thereby adjusting the position of the lateral opening of the valve.

[0040] In order to coordinate with the positioning of the opening on the outer side of the valve, an optical positioning module 14 is fixedly mounted on the side wall of the outer mounting seat 92 .

[0041] While the second conveyor belt controls the valve to rotate, the optical positioning module 14 starts to start and scans and identifies the position of the opening on the valve surface. When the opening is scanned to be directly above or below the lateral extrusion sealing head 94, the optical positioning module 14 controls the second conveyor belt to close, and then adjusts the height of the outer mounting seat 92 until the lateral extrusion sealing head 94 is aligned with the outer opening of the valve. Then, the first electrically controlled strut 93 is started to insert the lateral extrusion sealing head 94 into the outer opening of the valve to seal the outer opening of the valve. At the same time, the top elevator 8 controls the top detection cover 7 to descend, close the opening at the upper end of the valve, and complete the closure of all external openings of the valve.

[0042] During detection, fluid, which can be air or water vapor, is input into the external connection valve 12 through the external inlet pipe 13 until the pressure sensor module 95 detects that the internal pressure reaches the maximum set value. Then, the volume inside the valve can be calculated based on the built-in flow monitoring module of the external connection valve 12, and its sealing can be detected based on the pressure change.

[0043] In order to cooperate with height adjustment, a longitudinal rack 15 is fixedly installed on the outer side of the lateral frame 5 at one side of the longitudinal guide rail 91, and an adjustment motor 16 that cooperates with the longitudinal rack 15 is fixedly installed inside the outer mounting seat 92.

[0044] The adjusting motor 16 meshes with the longitudinal rack 15 through the lifting gear on its outer adjusting shaft, and controls the outer mounting seat 92 to rise and fall along the longitudinal guide rail 91 by controlling the rotation of the lifting gear. In conjunction with the rotation of the valve, the lateral extrusion sealing head 94 can be accurately aligned with the opening on the outer side of the valve.

[0045] In order to improve the bottom limiting capability of the valve, an arc-shaped adjustment slot 17 is provided on the inner arc surface of the arc-shaped limit correction frame 102 , and both sides of the arc-shaped adjustment slot 17 are slidably mounted with electrically controlled arc-shaped extension arms 18 .

[0046] The electrically controlled arc extension arm 18 includes a first arc extension arm and a second arc extension arm slidably assembled on both sides of the arc adjustment slot 17, a transverse electrically controlled screw fixed on the side wall of the connecting end of the arc limit correction frame 102, an internally threaded translation sleeve threadedly sleeved on the transverse electrically controlled screw, and a control connecting rod movably mounted on the outside of the internally threaded translation sleeve. The transverse electrically controlled screw controls the translation of the internally threaded translation sleeve by rotating, and the control connecting rod is used to control the sliding adjustment of the first arc extension arm and the second arc extension arm inside the arc adjustment slot 17.

The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
