Description

Technical Field

[0001] This utility model relates to the field of safety valve testing technology, and in particular to a safety valve testing device. Background Technology

[0002] A safety valve is a valve device used for automatic control of pressure systems. Its core function is to prevent the pressure in equipment or pipelines from exceeding a set value by discharging the medium, thereby avoiding major safety accidents such as explosions and leaks. The opening pressure and sealing performance of a safety valve directly affect its protective effect. During the production process, pressure tests and calibrations are required to verify its operational accuracy. For example, spring-loaded safety valves require testing to balance the spring load with the medium pressure to prevent losses due to component fatigue or material defects. Simultaneously, testing can identify potential problems with non-standard products (such as modified valves from scrapped parts), preventing accidents caused by dimensional inconsistencies or substandard sealing materials.

[0003] A search revealed a Chinese patent publication number CN117309370B, which discloses a safety valve testing device, comprising: an operating table and an assembly kit for fixing the safety valve. The operating table is equipped with multiple pairs of support columns, and a horizontal plate is mounted on the top of each support column. The horizontal plate is equipped with multiple sets of air injection and pressurization mechanisms, each of which includes a lifting air head and a drive assembly for driving the lifting air head to move up and down.

[0004] To address the issues in the aforementioned technologies where soapy water is reflected and sprayed onto the valve surface via a liquid reflector, resulting in uneven spraying, difficulty in observing the rear side, and the generation of numerous bubbles during impact, a safety valve detection device is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a safety valve detection device to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: it includes an installation platform, a plurality of bottom connectors are movably connected above the installation platform, a valve body is fixedly connected above the bottom connectors, a swing gear ring is fixedly connected to the top of the bottom connectors, a swing gear rod is slidably connected above the installation platform, the plurality of swing gear rings mesh with one side of the swing gear rod, a drive groove plate is fixedly connected to one end of the swing gear rod, and a drive assembly is movably connected to the inner side of the drive groove plate.

[0007] In some embodiments, the drive assembly includes a drive motor, a swing arm, and a roller. The drive motor is fixedly connected to the bottom of the mounting platform, one end of the swing arm is fixedly connected to the power output end of the drive motor, and the roller is rotatably connected to the other end of the swing arm and rotatably connected to the groove inside the drive slot plate.

[0008] In some embodiments, a top push rod and an air pump are fixedly connected to the top of the mounting platform, and a gas distributor is fixedly connected to the movable end below the top push rod. The air inlet of the gas distributor is fixedly connected to the air outlet of the air pump through a pipe.

[0009] In some embodiments, a plurality of top connectors are fixedly connected to the bottom of the gas distributor via a rotary joint, the other end of the top connectors is fixedly connected to the top of the valve body, and a gas pressure detection device is fixedly connected to the bottom connector via a rotary joint.

[0010] In some embodiments, a water supply component is fixedly connected to one side of the mounting platform, and a plurality of soap water nozzles are fixedly connected to the water outlet end of the water supply component through a pipe, with one end of each soap water nozzle fixedly connected to one side of the mounting platform.

[0011] In some embodiments, a plurality of swing grooves are provided on one side of the mounting platform, and a clamping rod is movably connected in the swing groove. A half gear is fixedly connected to the lower end of the clamping rod, and one side of the half gear is rotatably connected to the mounting platform.

[0012] In some embodiments, a plurality of positioning teeth are slidably connected to the inner side of the mounting platform, one side of the positioning teeth meshes with a half gear, and the upper ends of the plurality of positioning teeth are slidably connected to the outer side of the bottom connector.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] A safety valve testing device uses a drive motor to power a swing rod and rollers, causing the swing rack to reciprocate. This, in turn, drives the bottom connector to swing the valve body left and right, dynamically adjusting the position of the soap water spray. This design ensures that the soap water evenly covers the valve body surface, avoiding localized foam buildup that can interfere with observation due to fixed spraying, thus improving testing efficiency and accuracy.

[0016] A safety valve detection device, through the simultaneous operation of multiple bottom connectors, combined with a gas distributor and air pump, can synchronously inject detection gas into multiple valve bodies. The coordinated operation of the air pressure detection device and the soapy water nozzle allows for both leak detection via pressure changes and visual location of the leak point through foam formation.

[0017] A safety valve testing device drives a half gear through the downward pressure during valve body installation, which in turn links a positioning rack to complete three-way clamping. The clamping position is offset from the soap water nozzle to avoid interference. After the test is completed, a spring pushes the bottom connector to reset, achieving quick installation and clamping.

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0030] like Figure 1-6 As shown, a safety valve testing device includes a mounting platform 1. Multiple bottom connectors 9 are movably connected to the top of the mounting platform 1. A valve body 6 is fixedly connected to the top of the bottom connectors 9. A swing gear ring 19 is fixedly connected to the top of the bottom connectors 9. A swing gear rod 20 is slidably connected to the top of the mounting platform 1. Multiple swing gear rings 19 mesh with one side of the swing gear rod 20. A drive groove plate 22 is fixedly connected to one end of the swing gear rod 20. A drive assembly is movably connected to the inner side of the drive groove plate 22.

[0031] A water supply component 8 is fixedly connected to one side of the mounting platform 1. The water outlet of the water supply component 8 is fixedly connected to multiple soap water nozzles 7 through a pipe. One end of each soap water nozzle 7 is fixedly connected to one side of the mounting platform 1.

[0032] The mounting platform 1 has transparent glass guards on the front and sides. When in use, the valve body 6 can be inserted into the bottom connector 9 for fixation and testing. During the testing process, the water supply assembly 8 can be used to supply soapy water to multiple soap water nozzles 7 and spray it onto the side of the valve body 6 to check whether the valve body 6 leaks air during the testing process.

[0033] During this process, the drive assembly can be used to drive the swing rack 20 to swing laterally, which in turn drives the bottom connector 9 to swing left and right through the swing gear ring 19, thereby driving the valve body 6 to rotate. This allows the position of the valve body 6 to be sprayed with soapy water to be adjusted, enabling more even water spray detection. Furthermore, the position of the soapy water spray is always in front, making it easier to observe, and the soapy water will not cause foam due to repeated collisions, thus avoiding interference with observation.

[0034] In this embodiment, the driving assembly includes a drive motor 21, a swing arm 23, and a roller 24. The drive motor 21 is fixedly connected to the bottom of the mounting platform 1, one end of the swing arm 23 is fixedly connected to the power output end of the drive motor 21, and the roller 24 is rotatably connected to the other end of the swing arm 23. The roller 24 is rotatably connected to the groove inside the drive slot plate 22.

[0035] The drive motor 21 can drive the swing rod 23 to rotate, which in turn can drive the roller 24 to make circular motion, which can drive the drive slot plate 22 to make reciprocating linear motion, and thus drive the swing rack 20 to make reciprocating motion.

[0036] In this embodiment, a top push rod 2 and an air pump 3 are fixedly connected to the top of the mounting platform 1, and a gas distributor 4 is fixedly connected to the movable end below the top push rod 2. The air inlet end of the gas distributor 4 is fixedly connected to the air outlet end of the air pump 3 through a pipe.

[0037] Multiple top connectors 5 are fixedly connected to the bottom of the gas distributor 4 via a rotary joint. The other end of the top connector 5 is fixedly connected to the top of the valve body 6. A gas pressure detection device 12 is fixedly connected to the bottom connector 9 via a rotary joint.

[0038] The top push rod 2 can extend and press the top connector 5 downward to press it onto the valve body 6, thus fixing the valve body 6. The air pump 3 can inject gas into multiple valve bodies 6 through the gas distributor 4 for testing. The rotary joints on one end of the pipes of the top connector 5 and the bottom connector 9 can be used without affecting the rotation of the valve body 6 during testing. The air pressure detection device 12 can detect whether there is any air leakage in the valve body 6.

[0039] In this embodiment: there are transparent glass protective plates in front and on both sides of the mounting platform 1. When in use, the valve body 6 can be inserted into the bottom connector 9 for fixing and testing. During the testing process, the water supply component 8 can be used to supply soap water to multiple soap water nozzles 7 and spray it onto the side of the valve body 6 to test whether the valve body 6 leaks air during the testing process.

[0040] In this process, the drive component can be used to drive the swing rack 20 to swing laterally, which can drive the bottom connector 9 to swing left and right through the swing rack ring 19, thereby driving the valve body 6 to rotate. This can adjust the position of the valve body 6 where the soap water is sprayed, allowing for more even water spraying detection. The position of the soap water spray is always in front, making it easier to observe, and the soap water will not cause foam due to repeated collisions, thus avoiding interference with observation.

[0041] The drive motor 21 can drive the swing arm 23 to rotate, which in turn drives the roller 24 to make a circular motion. This drives the drive slot plate 22 to make a reciprocating linear motion, which in turn drives the swing rack 20 to make a reciprocating motion. The top push rod 2 can extend and press the top connector 5 downward to press it onto the valve body 6, thus fixing the valve body 6. The air pump 3 can inject gas into multiple valve bodies 6 through the gas distributor 4 for testing. The rotary joints on one end of the pipes of the top connector 5 and the bottom connector 9 can not affect the rotation of the valve body 6 during testing. The air pressure detection device 12 can detect whether there is an air leak in the valve body 6. Example 2

[0042] A safety valve detection device, this embodiment is based on embodiment 1 with the following improvements, such as... Figure 1-6 As shown,

[0043] In this embodiment, a plurality of swing grooves 18 are opened on one side of the mounting platform 1, and a clamping rod 15 is movably connected in the swing groove 18. A half gear 14 is fixedly connected to the lower end of the clamping rod 15, and one side of the half gear 14 is rotatably connected to the mounting platform 1.

[0044] Multiple positioning racks 13 are slidably connected to the inner side of the mounting platform 1. One side of the positioning rack 13 meshes with the half gear 14, and the upper ends of the multiple positioning racks 13 are slidably connected to the outer side of the bottom connector 9.

[0045] The clamping rod 15 can slide in the swing groove 18. When the valve body 6 is installed on the bottom connector 9, it will squeeze the bottom connector 9 to move downward. At this time, it can drive the positioning toothed rod 13 to move downward, thereby driving the half gear 14 to rotate, so that the clamping rod 15 clamps the valve body 6 from three sides. At the same time, the position of the clamping rod 15 is offset from the soap water nozzle 7, so as not to affect the detection of soap water spray.

[0046] In this embodiment, a support plate 11 is fixedly connected inside the mounting platform 1. A spring 10 is fixedly connected to the bottom of the support plate 11 and the bottom connector 9. A positioning rod 16 is slidably connected inside the mounting platform 1. One end of the positioning rod 16 is inserted into the side slot of the positioning tooth rod 13. A spring 2 17 is fixedly connected to the other side of the positioning rod 16 and the inside of the mounting platform 1.

[0047] After the positioning toothed rod 13 and the bottom connector 9 fall down, the positioning rod 16, which is L-shaped, can be inserted into one side of the positioning toothed rod 13 to prevent the bottom connector 9 from rising and resetting, and to fix the clamping rod 15. Spring 10 can use its elasticity to make the bottom connector 9 rise automatically, and spring 2 17 can prevent the positioning rod 16 from shaking and slipping off one side of the positioning toothed rod 13.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
