Description

Technical Field

[0001] This utility model belongs to the field of valve airtightness testing technology, and specifically relates to an airtightness testing device for valve casting production. Background Technology

[0002] Valve castings are valve part blanks obtained by pouring molten metal into a pre-made mold cavity, allowing it to cool and solidify, and then cleaning, heat treatment, and necessary subsequent processing. The castings constitute the main structural framework and fluid passage of the valve.

[0003] In existing technologies, a cylinder is typically used to drive a sealing device to seal both ends of the valve. The sealing device then pressurizes the inside of the valve by filling it with air. The valve is then placed in water, and the airtightness of the valve is tested by observing whether bubbles emerge from the water. However, the airtightness of the valve needs to be tested one by one, which is not convenient for continuous testing and reduces the efficiency of valve airtightness testing. Utility Model Content

[0004] To address the issue that valve airtightness testing involves sealing both ends of a valve using a cylinder-driven sealing device, pressurizing the valve's interior with air, and then submerging the valve in water to observe for bubbles, the current method requires testing each valve individually, hindering continuous testing and reducing efficiency. This invention proposes an airtightness testing device for valve casting production to overcome these existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an airtightness testing device for valve casting production, comprising a housing:

[0007] The housing is equipped with a drive assembly, a transmission assembly, a tilting assembly, a detection assembly, and an air supply assembly.

[0008] The drive assembly has its output end fixedly installed inside the transmission assembly, so that the drive assembly drives the transmission assembly to rotate.

[0009] The flipping component is fixedly installed inside the transmission component on the outer surface of the transmission component so that the rotation of the transmission component drives the flipping component to flip.

[0010] The detection component is fixedly installed on one side of the flipping component, so that when the flipping component flips, it drives the detection component to flip as well, for the purpose of detecting the airtightness of the valve casting.

[0011] The gas delivery assembly is fixedly installed at its bottom end to the top end of the transmission assembly, so that the transmission assembly rotates to drive the gas delivery assembly to rotate.

[0012] Furthermore, the drive assembly includes a mounting bracket, the top of which is fixedly mounted to the inside of the housing, and a motor is fixedly mounted at the bottom of the mounting bracket.

[0013] Furthermore, the transmission assembly includes a drive gear, the inside of which is fixedly installed with the output end of the motor, a driven gear meshing with the surface of the drive gear, a support shaft rotatably connected inside the driven gear, the bottom end of the support shaft being fixedly installed with the top end of the housing, and an internal gear ring meshing with the surface of the driven gear.

[0014] Furthermore, the flipping assembly includes a turntable, the bottom end of which is rotatably disposed with the top end of the housing, the interior of the turntable being fixedly installed with the outer surface of the internal gear ring, a rotating seat being fixedly installed at the top end of the turntable, and a mounting frame being rotatably disposed inside the rotating seat.

[0015] Furthermore, the flipping assembly also includes a limiting cylinder, the bottom end of which is fixedly installed to the top end of the housing. The outer surface of the limiting cylinder is provided with a high and low groove, and a guide rod is slidably arranged inside the high and low groove. A connecting frame is fixedly installed at one end of the guide rod, and one side of the connecting frame is fixedly installed to one side of the mounting frame.

[0016] Furthermore, the detection assembly includes a cylinder and an adjusting rod.

[0019] 1. This utility model drives the transmission component installed at the output end of the start-up drive component to rotate, so that the transmission component drives the flipping component installed on the outer surface to rotate. After the flipping component rotates to a designated position, one end of it rotates downward, thereby enabling the flipping component to drive the detection component installed on the inner side to rotate. During the rotation of the detection component, the valve casting is gradually driven into the water pool opened at the top of the shell, so that the water submerges the valve casting.

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] Please see Figures 1-6 As shown, this utility model is an airtightness testing device for valve casting production, including a housing 1:

[0034] The housing 1 is respectively provided with a drive assembly 2, a transmission assembly 3, a tilting assembly 4, a detection assembly 5, and an air supply assembly 6;

[0035] The drive assembly 2 is fixedly installed inside the transmission assembly 3 at its output end, so that the drive assembly 2 drives the transmission assembly 3 to rotate.

[0036] The flipping component 4 is fixedly installed inside the transmission component 3 so that the transmission component 3 rotates and drives the flipping component 4 to flip.

[0037] The detection component 5 is fixedly installed on one side of the flipping component 4, so that when the flipping component 4 flips, it drives the detection component 5 to flip as well, so as to detect the airtightness of the valve casting.

[0038] The bottom end of the gas delivery assembly 6 is fixedly installed to the top end of the transmission assembly 3 so that the transmission assembly 3 drives the gas delivery assembly 6 to rotate when it rotates.

[0039] In use, the air outlet of the air supply component 6 is connected to the detection component 5 via an air pipe, allowing the air supply component 6 to control the detection component 5 to detect the valve casting. The valve casting is then placed horizontally inside the detection component 5. The detection component 5 is then activated to seal both ends of the valve casting. The drive component 2 is then activated to drive the transmission component 3 installed at the output end to rotate, causing the transmission component 3 to drive the rotating component 4 installed on the outer surface to rotate. After the rotating component 4 rotates to a designated position, one end of it rotates downwards, thereby causing the rotating component 4 to drive the detection component 5 installed on the inner side to rotate. During the rotation of the detection component 5, the valve casting is gradually driven into the water pool opened at the top of the housing 1, so that the water submerges the valve casting. The presence of air bubbles is then observed. Since multiple sets of rotating components 4 and detection components 5 are provided, continuous detection of the valve casting is facilitated.

[0040] This invention drives the transmission component 3 installed at the output end of the drive component 2 to rotate, so that the transmission component 3 drives the flipping component 4 installed on the outer surface to rotate. After the flipping component 4 rotates to a designated position, one end of it rotates downward, thereby enabling the flipping component 4 to drive the detection component 5 installed on the inner side to rotate. During the rotation of the detection component 5, the valve casting can be gradually driven into the water pool opened at the top of the housing 1, so that the water submerges the valve casting. Then, the presence of air bubbles is observed. Since multiple sets of flipping component 4 and detection component 5 are provided, it is convenient to continuously detect the valve casting, thereby improving the detection efficiency of the valve casting's airtightness.

[0041] In one embodiment, the drive assembly 2 includes a mounting bracket 201, the top of which is fixedly mounted to the inside of the housing 1, and a motor 202 is fixedly mounted at the bottom of the mounting bracket 201.

[0042] The mounting bracket 201 is designed to support the motor 202 mounted at the bottom, thereby improving the stability of the motor 202 during operation.

[0043] In one embodiment, the transmission assembly 3 includes a drive gear 301, the inside of which is fixedly installed with the output end of the motor 202, a driven gear 302 meshing with the surface of the drive gear 301, a support shaft 303 rotatably connected inside the driven gear 302, the bottom end of the support shaft 303 being fixedly installed with the top end of the housing 1, and an internal gear ring 304 meshing with the surface of the driven gear 302.

[0044] The drive gear 301 installed at the output end is driven to rotate by starting the motor 202, so that the drive gear 301 drives the driven gear 302 that is surface-meshing. Since the interior of the driven gear 302 is rotatably set with the outer surface of the support shaft 303, and the surface of the driven gear 302 meshes with the surface of the internal gear ring 304, when the driven gear 302 rotates, it can drive the internal gear ring 304 to rotate, which is quite convenient.

[0045] In one embodiment, the flipping assembly 4 includes a turntable 401, the bottom end of which is rotatably disposed from the top end of the housing 1, the interior of the turntable 401 is fixedly installed on the outer surface of the internal gear ring 304, a rotating seat 402 is fixedly installed on the top end of the turntable 401, and a mounting frame 403 is rotatably disposed inside the rotating seat 402.

[0046] The flipping assembly 4 also includes a limiting cylinder 404, the bottom end of which is fixedly installed with the top end of the housing 1. The outer surface of the limiting cylinder 404 is provided with a high-low groove 405, and a guide rod 406 is slidably arranged inside the high-low groove 405. A connecting frame 407 is fixedly installed at one end of the guide rod 406, and one side of the connecting frame 407 is fixedly installed with one side of the mounting frame 403.

[0047] When the internal gear ring 304 rotates, it drives the turntable 401 mounted on its outer surface to rotate, which in turn drives the rotating seat 402 mounted on its top to rotate. This causes the rotating seat 402 to drive the internally rotating mounting frame 403 to rotate in a circular motion. Consequently, the mounting frame 403 drives the connecting frame 407 mounted on one side to rotate in a circular motion. Since a guide rod 406 is fixedly connected to one side of the connecting frame 407, and the outer surface of the guide rod 406 is slidably disposed with the interior of the high and low groove 405, when the connecting frame 407 drives the guide rod 406 to move to the high position of the high and low groove 405, the guide rod 406 can drive the connecting frame 407 to move along the direction of the high and low groove 405. This causes the connecting frame 407 to drive the mounting frame 403 mounted on one side to rotate around the rotating seat 402, thus facilitating the flipping of one side of the mounting frame 403.

[0048] In one embodiment, the detection component 5 includes a cylinder 501 and an adjusting rod 502. One side of the cylinder 501 is fixedly installed to the inner side of the mounting frame 403. A pneumatic head 503 is fixedly installed at the telescopic end of the cylinder 501. One end of the adjusting rod 502 is fixedly connected to one side of the mounting frame 403. An adjusting plate 504 is fixedly installed on the outer surface of the adjusting rod 502. A sealing head 505 is fixedly installed on one side of the adjusting plate 504.

[0049] By placing the valve casting between the pneumatic head 503 and the sealing head 505, and then activating the cylinder 501 to drive the pneumatic head 503 installed at the telescopic end to move, the pneumatic head 503 is brought into contact with one end of the valve casting during the movement, and works with the sealing head 505 to seal both ends of the valve casting. When one side of the mounting frame 403 is flipped, it can cause the cylinder 501 installed on the inner side to flip, so that the cylinder 501 drives the pneumatic head 503 to flip, and the mounting frame 403 can also cause the adjusting rod 502 fixed on one side to flip, so that the adjusting rod 502 drives the adjusting plate 504 to flip, so that the adjusting plate 504 drives the sealing head 505 to flip, so that the pneumatic head 503 and the sealing head 505 can flip the valve casting, thus facilitating the flipping of the valve casting into the water tank opened at the top of the housing 1 for airtightness testing.

[0050] In one embodiment, the gas delivery assembly 6 includes a support frame 601, the bottom end of which is fixedly installed to the top end of the turntable 401. An outer air cylinder 602 is fixedly installed inside the support frame 601, and an inner air cylinder 603 is rotatably arranged inside the outer air cylinder 602. A positioning frame 604 is fixedly installed on the outer surface of the inner air cylinder 603, and the bottom end of the positioning frame 604 is fixedly installed to the top end of the housing 1.

[0051] The turntable 401 drives the external air cylinder 602 to rotate, so that the air nozzle of the external air cylinder 602 is connected to the cylinder 501 and the air pressure head 503 through the pipe, so as to facilitate the use of the cylinder 501 and the air pressure head 503. The external air cylinder 602 can rotate with the cylinder 501, thereby avoiding pipe entanglement, which is more convenient.

[0052] Through the above technical solution, 1. The drive component 2 drives the transmission component 3 installed at the output end to rotate, so that the transmission component 3 drives the flipping component 4 installed on the outer surface to rotate. After the flipping component 4 rotates to the designated position, one end of it rotates downward, so that the flipping component 4 drives the detection component 5 installed on the inner side to rotate. During the rotation of the detection component 5, the valve casting can be gradually driven into the water pool opened at the top of the housing 1, so that the water submerges the valve casting. Then, by observing whether there are air bubbles, since there are multiple sets of flipping component 4 and detection component 5, it is convenient to continuously detect the valve casting, thereby improving the detection efficiency of the airtightness of the valve casting.

[0053] 2. By placing the valve casting between the pneumatic head 503 and the sealing head 505, and then starting the cylinder 501 to drive the pneumatic head 503 installed at the telescopic end to move, the pneumatic head 503 will come into contact with one end of the valve casting during the movement, and cooperate with the sealing head 505 to seal both ends of the valve casting. When one side of the mounting frame 403 is flipped, it can drive the cylinder 501 installed on the inner side to flip, so that the cylinder 501 drives the pneumatic head 503 to flip, and the mounting frame 403 can drive the adjusting rod 502 fixed on one side to flip, so that the adjusting rod 502 drives the adjusting plate 504 to flip, so that the adjusting plate 504 drives the sealing head 505 to flip, so that the pneumatic head 503 and the sealing head 505 can drive the valve casting to flip, thus facilitating the flipping of the valve casting into the water pool opened at the top of the housing 1 for airtightness testing.
