[0002] Breather valves are commonly used in various types of storage tanks and pressure vessels. These valves utilize their breathing system to maintain normal pressure within these tanks and pressure vessels. The inspection procedures for these valves are detailed in the Technical Specifications for Inspection of Safety Accessories for In-Service Vertical Cylindrical Steel Welded Storage Tanks.

[0003] During the current testing process, it is generally necessary to remove the breathing valve body and perform pressure relief / pressurization testing at the valve inlet. During the actual testing process, a blocking plate is required to isolate the breathing valve from the tank body and pressure vessel, and the installation / removal of the blocking plate is relatively cumbersome. When pressure changes occur in the tank or pressure vessel, if the pressure inside the tank exceeds or falls below the limit, it is prone to explosion or deflation, posing a serious accident hazard. The currently used reverse pressure differential method of testing has problems such as poor sealing and short-term fluctuations in the air extraction / intake flow due to human factors, resulting in reduced detection accuracy.

[0032] Referring to Figures 1 to 6 The novel breathing valve 6 detection device comprises a sealing piece 3, a plug disc 1, a tensioning structure 4 and a detection assembly.

[0033] The sealing piece 3 is provided with a force applying wall surface and a sealing wall surface, specifically, the sealing wall surface is used for abutting and sealing with the outlet of the breathing valve 6, and the force applying wall surface is used for abutting with the plug disc 1, so that the sealing piece 3 keeps abutting and sealing with the breathing valve 6.

[0034] Specifically, in the embodiment, the sealing piece 3 comprises a side sealing part 31 and an end sealing part 32, the side sealing part 31 and the end sealing part 32 are integrally arranged, the side sealing part 31 is in a cylindrical structure, and the end sealing part 32 is in a round cake structure. The inner side surface of the side sealing part 31 and the end surface of the end sealing part 32 close to the breathing valve 6 are combined to form the sealing wall surface. The inner wall surface of the side sealing part 31 is used for sealing connection with the outer peripheral surface of the outlet of the breathing valve 6 through abutting, and the end surface of the end sealing part 32 close to the breathing valve 6 is used for sealing connection with the end surface of the outlet of the breathing valve 6 through abutting. The force applying wall surface is the end surface of the end sealing part 32 away from the breathing valve 6.

[0035] The end sealing part 32 of the sealing piece 3 is provided with two round holes. In other embodiments, a large round hole can be provided in the end sealing part 32 of the sealing piece 3, and those skilled in the art can select the size of the hole in the end sealing part 32 according to actual needs.

[0036] The end surface of the plug disc 1 and the force applying wall surface are in sealing connection through abutting.

[0037] The plug disc 1 is provided with a detection interface 12 and a endoscope interface 13. The detection interface 12 and the endoscope interface 13 are correspondingly arranged with the two round holes provided in the end sealing part 32, and the detection interface 12 and the endoscope interface 13 are respectively in communication with the corresponding round holes.

[0038] By arranging the endoscope interface 13 in the plug disc 1, the endoscope and other components can be connected through the endoscope interface 13 before detecting the breathing valve 6, and the inside of the breathing valve 6 is observed by using the endoscope to determine whether the valve body is suitable for detection. If there is damage or blockage in the inside of the valve body, it can be directly disassembled and repaired, thereby improving the detection efficiency. During detection, the endoscope interface 13 is blocked by the locking nut, thereby ensuring the sealing of the entire novel breathing valve 6 detection device.

[0039] The plug disc 1 is provided with four through holes 11 arranged in a rectangular shape.

[0040] The tensioning structure 4 passes through the breather valve 6 and abuts against the breather valve 6, and the two ends of the tensioning structure 4 are connected with the plug disc 1, so as to realize the close connection of the plug disc 1, the sealing element 3 and the breather valve 6. Specifically, in the embodiment, the tensioning structure 4 comprises a strap head 41 and a strap body 42, the strap body 42 passes through the through hole 11 of the plug disc 1, and the strap head 41 is limited by the plug disc 1 and cannot pass through the through hole 11, one strap head 41 of the tensioning structure 4 is arranged at each through hole 11, and the strap body 42 of each tensioning structure 4 passes through the through hole 11, wherein the strap body 42 of one strap is inserted into the strap head 41 of the other strap opposite to the strap body 42, so as to realize the fixation of the plug disc 1.

[0041] The tensioning structure 4 applies an axial force of the plug disc 1 to the sealing element 3, so as to realize the close connection of the plug disc 1, the sealing element 3 and the breather valve 6, to improve the sealing specific pressure and ensure the sealing, so as to ensure the sealing between the sealing element 3 and the breather valve 6.

[0042] In other embodiments, the tensioning structure 4 can also be provided as a clamp, and a person skilled in the art can select the specific structure of the tensioning structure 4 according to actual needs.

[0043] The clamp structure 2 is further included, and the clamp structure 2 is sleeved on the side sealing part 31 and is used for keeping the side sealing part 31 sealed with the outer circumferential surface of the outlet of the breather valve 6.

[0044] The detection assembly comprises a connecting pipeline, a differential pressure gauge 52, a flow meter 53, a pressure gauge 54, a pressure regulating valve 55 and a manual pressure regulating device 56.

[0045] The differential pressure gauge 52, the detection interface 12 and the connecting pipeline are connected through a three-way interface. By arranging the differential pressure gauge 52, the change of the differential pressure before and after the opening and closing of the breather valve 6 can be detected, so as to quickly judge whether the breather valve 6 is qualified.

[0046] The flow meter 53, the pressure gauge 54, the pressure regulating valve 55 and the manual pressure regulating device 56 are connected with the connecting pipeline. The flow meter 53, the pressure gauge 54, the pressure regulating valve 55 and the manual pressure regulating device 56 are connected through a four-way interface. By additionally arranging the flow meter 53 and the pressure gauge 54, the problem of detection precision reduction caused by the pressure fluctuation in the detection device due to human factors can be effectively avoided.

[0047] Specifically, in this embodiment, the manual pressure regulating device 56 can be set as a manual vacuum pump or a gas cylinder. The manual pressure regulating device 56 is used to replace the traditional electric vacuum pump while ensuring the sealing of the detection device, which greatly reduces the burden on the detection personnel, effectively improves the adaptability to the actual detection environment, and improves the detection efficiency.

[0048] After ensuring that the detection device is installed properly, check the inhalation / exhalation pressure of the breathing valve 6, select a manual vacuum pump or gas cylinder to connect with the connecting pipe according to actual needs, and use the locking nut to close the endoscope interface 13.

[0049] Ensure that the seal 3 is in contact with the plugging disc 1 and connected to the outlet of the breathing valve 6. Pass the belt body 42 of the tensioning structure 4 through the four perforations 11 on the plugging disc 1, and then pass the belt body 42 of the tensioning structure 4 around the breathing valve 6, and then pass it through the tie head 41 of another tensioning structure 4 to tightly connect the plugging disc 1, the seal 3 and the breathing valve 6, thereby applying axial force to the seal 3.

[0050] Furthermore, by using the clamp structure 2 , the side sealing portion 31 is closely fitted to the outer peripheral surface of the outlet of the breathing valve 6 , thereby imparting an annular force to the sealing member 3 .

[0051] The pressure between the sealing member 3 and the outlet of the breathing valve 6 is enhanced by the clamp structure 2 and the tensioning structure 4, thereby effectively improving the sealing performance of the detection device.

[0052] During the test, close the pressure regulating valve 55 and use the manual pressure regulating device 56 (a manual vacuum pump or gas cylinder) to evacuate / introduce air into the device. By observing the changes in the differential pressure gauge 52, the corresponding value can be calculated to determine whether the breathing valve 6 is qualified. During the test, the tester needs to observe the values ​​of the flow meter 53 and pressure gauge 54 to avoid large fluctuations that may affect the accuracy of the test.

[0053] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
