Description

Technical Field

[0001] This utility model relates to the technical field of safety valve calibration devices, and in particular to a multifunctional safety valve calibration device. Background Technology

[0002] Existing safety valve calibration devices, such as the multifunctional safety valve calibration device with patent number CN222318342U, can better observe whether the safety valve is leaking by using a sealing cover and a solution tank. However, in addition to the straight-type safety valves detected by the aforementioned patent, there are also safety valves with L-shaped inlets and outlets, which the aforementioned device cannot detect, thus reducing its application range. Utility Model Content

[0003] Therefore, it is necessary to provide a multifunctional safety valve calibration device to address the technical problem of the limited applicability of the aforementioned safety valve calibration devices.

[0004] To achieve the above objectives, this utility model provides a multifunctional safety valve calibration device, including a frame, a fixed sealing gasket mounted on the frame, a rotating frame rotatably mounted on the frame, a movable sealing gasket slidably engaged on the rotating frame, a drive mechanism for driving the rotating frame to rotate mounted on the frame, an abutment frame slidably engaged on the frame, an upper linear drive mechanism and a side linear drive mechanism mounted on the frame, a push frame mounted at the output end of the side linear drive mechanism, an air inlet pipe mounted on the fixed sealing gasket, the input end of the air inlet pipe being connected to a gas pressure source, and an air outlet pipe mounted on the movable sealing gasket, the output end of the air outlet pipe being connected to a solution tank.

[0005] Preferably, the frame is provided with inclined grooves, and there are two inclined grooves arranged symmetrically, with the abutment frame slidingly engaged in the inclined grooves.

[0006] Preferably, the pusher is provided with a slot, and the abutment is slidably engaged in the slot.

[0007] Preferably, a measuring tube is installed on the fixed sealing gasket, and a pressure gauge is installed on the frame, with the measuring tube connected to the pressure gauge.

[0008] Preferably, the drive mechanism includes a first gear, which is mounted on a rotating frame. A rotary drive device is mounted on the frame, and a second gear is mounted on the output end of the rotary drive device. The first gear and the second gear are meshed together.

[0009] Preferably, an abutment shaft is rotatably mounted on the abutment frame.

[0010] Preferably, a spring is installed inside the abutment frame, and the output end of the spring is connected to the movable sealing gasket.

[0011] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0012] 1. By cooperating with the rotating frame and the upper linear drive mechanism and the side linear drive mechanism, the moving sealing gasket is positioned in different positions, thus forming an L-shape or a straight line with the fixed sealing gasket, thereby enabling the calibration of different types of safety valves.

[0013] 2. By setting up the push frame, the side linear drive mechanism can push the moving sealing gasket or abutment frame according to the different types of safety valves detected, thereby further improving practicality. Attached Figure Description

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 3This application provides a multifunctional safety valve calibration device, including a fixed sealing gasket 2 fixedly mounted on a frame 1, a rotating frame 3 rotatably mounted on the frame 1, a movable sealing gasket 4 slidably engaged on the rotating frame 3, both the fixed sealing gasket 2 and the movable sealing gasket 4 being thin, airtight, and elastic soft pads mounted on rigid mounting plates, a drive mechanism for rotating the rotating frame 3 mounted on the frame 1, an abutment frame 5 slidably engaged on the frame 1, and an upper linear drive mechanism 6 and a side linear drive mechanism 7 mounted on the frame 1. Both the upper linear drive mechanism 6 and the side linear drive mechanism 7 are preferably electric cylinders. The output end of the side linear drive mechanism 7 is equipped with a push frame 8. An air inlet pipe 9 is fixedly installed on the fixed sealing gasket 2. The input end of the air inlet pipe 9 is connected to the air pressure source 10, which can be an air pump. An air outlet pipe 11 is fixedly installed on the movable sealing gasket 4. The air outlet pipe 11 is preferably a retractable hose and is limited and fixed. When the rotating frame 3 rotates, the air outlet pipe 11 will not affect the detection work. The output end of the air outlet pipe 11 is connected to the solution tank 12.

[0020] In this embodiment, the pusher 8 is V-shaped, with a square long push rod installed in the middle for pushing the movable sealing gasket 4. When dealing with a safety valve with a straight inlet and outlet, the side linear drive mechanism 7 drives the pusher 8 to directly push the movable sealing gasket 4, thereby fixing the sealing gasket 2 on the opposite side to cooperate with the movable sealing gasket 4, jointly squeezing and sealing the inlet and outlet of the safety valve. When dealing with a safety valve with an L-shaped inlet and outlet, the drive mechanism drives the rotating frame 3 and the movable sealing gasket 4 on it to rotate, so that the movable sealing gasket 4 and the fixed sealing gasket 2 are also set in an L-shape. At this time, the side linear drive mechanism 7 pushes the abutment frame 5 forward and cooperates with the fixed sealing gasket 2 to squeeze the safety valve. Then, the upper linear drive mechanism 6 presses down, so that the movable sealing gasket 4 can close one of the inlets and outlets of the L-shaped inlet and outlet. After the safety valve inlet and outlet are sealed, the air pressure source 10 pressurizes one of the safety valve inlets and outlets through the air inlet pipe 9. At this time, the safety valve can be in the closed state. When the other inlet and outlet of the safety valve exhausts air out through the air outlet pipe 11 and enters the solution tank 12 and is observed, this safety valve is unqualified; otherwise, it is qualified. The safety valve inlet and outlet protrude from the cylindrical body, and the movable sealing gasket 4 has a certain thickness, so that the movable sealing gasket 4 can first abut against the safety valve with the abutment frame 5. When the pusher 8 pushes the movable sealing gasket 4, it can successfully seal one of the safety valve inlets and outlets. When the pusher 8 pushes the abutment frame 5 to compress and fix the safety valve body, the square long push rod on the pusher 8 is farther away from the safety valve body than the abutment frame 5, so the abutment frame 5 can fix the safety valve first.

[0021] In some embodiments, to facilitate the pressing and fixing of the safety valve by the abutment frame 5, the frame 1 is provided with two inclined grooves 13, which are symmetrically arranged. The abutment frame 5 is slidably engaged in the inclined grooves 13. The closer the inclined groove 13 is to the fixed sealing gasket 2, the smaller the distance between the two inclined grooves 13, so that the two abutment frames 5 can form a stable triangular pressing structure with the fixed sealing gasket 2.

[0022] In some embodiments, in order to facilitate timely repositioning of the abutment frame 5 after it is pushed out, a slot is provided on the push frame 8, and the abutment frame 5 is slidably engaged in the slot.

[0023] In some embodiments, to facilitate pressure monitoring during safety valve calibration, a measuring tube 14 is fixedly mounted on the fixed sealing gasket 2, and a pressure gauge 15 is fixedly mounted on the frame 1. The measuring tube 14 is connected to the pressure gauge 15. The pressure gauge 15 can monitor the input gas pressure when the gas pressure source 10 supplies gas to the safety valve for pressurization.

[0024] In some embodiments, to facilitate the rotation of the rotating frame 3, a drive mechanism is provided including a gear 16, which is rotatably mounted on the rotating frame 3. A rotary drive device 17 is fixedly mounted on the frame 1. The rotary drive device 17 is preferably a servo motor. A gear 18 is mounted on the output end of the rotary drive device 17, and the gear 16 and gear 18 are meshed together. Thus, through the meshing connection of the gear 16 and gear 18, when the output end of the rotary drive device 17 rotates, it can drive the rotating frame 3 to rotate together.

[0025] In some embodiments, to facilitate the compression and fixing of the cylindrical body of the safety valve, an abutment shaft 19 is rotatably mounted on the abutment frame 5. The safety valve is fixed by the abutment shaft 19, thereby enabling compression and fixing of safety valves of different sizes. Compared with the square abutment frame 5, which has an invariable tilt angle, it can better contact and abut with the safety valve.

[0026] In some embodiments, to facilitate the repositioning of the movable sealing gasket 4 after movement, a spring 20 is fixedly installed inside the abutment frame 5, and the output end of the spring 20 is connected to the movable sealing gasket 4.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
