Description

Technical Field

[0001] The utility model relates to the technical field of breather valve detection, in particular to a new type of breather valve inlet tooling. Background Art

[0002] A breather valve is a type of valve commonly used in various storage tanks and pressure vessels. This valve uses its respiratory system to ensure the normal pressure inside various storage tanks and pressure vessels. When detecting the breather valve, its detection method is specified in detail in the inspection technical specification for safety accessories of in-service vertical cylindrical steel welded storage tanks.

[0003] During the detection process of the breather valve, it is generally necessary to remove the breather valve body and perform pressure relief / pressurization from the valve inlet for detection. In the actual detection process, it is necessary to isolate the breather valve from the pressure vessel through a blind plate, and the installation and disassembly of the blind plate are relatively cumbersome. When the pressure in the pressure vessel changes, if the pressure in the pressure vessel exceeds or is lower than the limit value, an explosion may occur or the pressure vessel may collapse, posing serious potential accident hazards. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is: to provide a new type of breather valve inlet tooling to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0009] Through the above technical solution, by installing this new type of breather valve inlet tooling between the traditional breather valve and the pressure vessel, the effect of rapid plugging can be achieved by inflating the expansion plugging structure to separate the pressure vessel and the breather valve. Compared with the plugging methods such as using a solid blind plate, the plugging speed is greatly increased, which can effectively reduce the weight borne by the detection personnel, thereby improving the inspection efficiency.

[0010] As a further improvement of the above technical solution, connecting flanges are respectively and fixedly arranged at both ends of the tooling body.

[0011] Through the above technical solution, the connecting flanges at both ends of the tooling body are respectively connected to the breathing valve and the pressure vessel.

[0012] As a further improvement of the above technical solution, two limiting blocking nets are fixedly arranged inside the tooling body, and the two limiting blocking nets are respectively arranged on both sides of the blocking space.

[0013] Through the above technical solution, when the expansion blocking structure expands due to the injection of the medium and abuts against the two limiting blocking nets on both sides, the limiting blocking nets can limit the expansion blocking structure to prevent the expansion blocking structure from leaving the blocking space when expanding or the expansion blocking structure from expanding excessively, thereby avoiding the contact between the expansion blocking structure and other components of the tooling body and ensuring the normal operation of other components of the tooling body.

[0014] As a further improvement of the above technical solution, it further includes an interface closing member. The tooling body is provided with a plurality of functional interfaces, and the interface closing member is detachably connected to the functional interfaces, and the plurality of functional interfaces are closed by the interface closing member.

[0015] Through the above technical solution, when the functional interfaces are not needed, the interface closing member blocks the functional interfaces.

[0016] As a further improvement of the above technical solution, the functional interface includes an endoscope interface, and the endoscope interface is arranged on the breathing valve side and is used for allowing the endoscope to enter the tooling body.

[0017] Through the above technical solution, by providing the endoscope interface, the endoscope can be inserted into the interior of the tooling body from the endoscope interface before detection, and then the interior of the breathing valve can be observed through the endoscope for damage. If there is damage inside the breathing valve, the breathing valve can be directly disassembled and repaired, which can greatly optimize the detection efficiency. After the endoscope is used, the endoscope is removed, and the interface closing member is reconnected to the endoscope interface to block the endoscope interface.

[0018] As a further improvement of the above technical solution, the functional interface includes a first pressure gauge installation interface, and the first pressure gauge installation interface is arranged on the breathing valve side.

[0019] Through the above technical solution, after installing a pressure gauge on the first pressure gauge installation interface, the pressure on the breathing valve side can be detected.

[0020] As a further improvement of the above technical solution, the functional interface further includes a first pressure regulation interface, and the first pressure regulation interface is arranged on the breathing valve side.

[0022] As a further improvement of the above technical solution, the function interface includes a second pressure gauge installation interface, and the second pressure gauge installation interface is arranged on the side of the pressure vessel.

[0023] Through the above technical solution, after installing a pressure gauge at the second pressure gauge installation interface, during the detection process, the staff can always observe whether the value of the pressure gauge connected to the second pressure gauge installation interface is within the specified limit of the pressure vessel. If the displayed pressure exceeds the specified value limit, the staff needs to perform other operations to ensure that the pressure of the pressure vessel is within the specified limit.

[0024] As a further improvement of the above technical solution, the function interface further includes a second pressure regulating interface, and the second pressure regulating interface is arranged on the side of the pressure vessel.

[0025] Through the above technical solution, the second pressure regulating interface can be connected to a pressure regulating component, and the pressure regulating component can regulate the pressure in the pressure vessel. In the non-detection state, the pressure regulating component is in the closed state. During the detection process, the staff always observes the value of the pressure gauge connected to the second pressure gauge installation interface. When the value of the pressure gauge exceeds the specified limit of the pressure vessel, the pressure regulating component is opened. When the pressure of the pressure vessel is greater than the upper limit of the specified limit, the pressure regulating component relieves the pressure of the pressure vessel; when the pressure of the pressure vessel is less than the lower limit of the specified limit, the pressure regulating component pressurizes the pressure vessel, thereby ensuring the safety of the detection.

[0026] As a further improvement of the above technical solution, the expansion plugging structure is a rubber member.

[0036] Referring to Figure 1 and Figure 2 , a new type of breather valve inlet tooling, including a tooling body 100, a plugging component 200 and a plurality of interface closing members 300.

[0037] Both ends of the tooling body 100 are provided with connection flanges, and the two connection flanges are respectively set as the upper flange 110 and the lower flange 120. The upper flange 110 is connected to the air inlet of the breathing valve, and the lower flange 120 is connected to the breathing valve installation port of the pressure vessel.

[0038] A blocking space 101 is arranged in the middle of the tooling body 100, and both sides of the blocking space 101 are respectively set as the pressure vessel side and the breathing valve side.

[0039] A restricting and blocking net 130 is installed inside the tooling body 100. The number of the restricting and blocking nets 130 is set to two, and the two restricting and blocking nets 130 are respectively arranged on both sides of the blocking space 101. The restricting and blocking net 130 can be set as a mesh structure or a grid structure, and those skilled in the art can select the specific structure of the restricting and blocking net 130 according to actual needs.

[0040] The tooling body 100 is provided with a plurality of functional interfaces, and the plurality of functional interfaces are correspondingly arranged with a plurality of interface closing members 300. The functional interfaces are threadedly connected to the interface closing members 300, so that the functional interfaces and the interface closing members 300 are detachably connected, thereby realizing the closing and opening of the functional interfaces.

[0041] The plurality of functional interfaces are respectively set as an endoscope interface 106, a first pressure gauge installation interface 102, a first pressure regulation interface 103, a second pressure gauge installation interface 104, and a second pressure regulation interface 105.

[0042] Among them, the endoscope interface 106, the first pressure gauge installation interface 102, and the first pressure regulation interface 103 are all arranged on the breathing valve side. The second pressure gauge installation interface 104 and the second pressure regulation interface 105 are all arranged on the pressure vessel side.

[0043] The first pressure gauge installation interface 102 and the first pressure regulation interface 103 are arranged in a 180-degree layout with respect to the central axis of the tooling body 100. The endoscope interface 106 is arranged between the first pressure gauge installation interface 102 and the first pressure regulation interface 103, and the endoscope interface 106 and the first pressure gauge installation interface 102 are arranged in a 90-degree layout with respect to the central axis of the tooling body 100.

[0044] By setting the endoscope interface 106, before detection, the endoscope can be inserted into the interior of the tooling body 100 from the endoscope interface 106, and then the interior of the breathing valve can be observed through the endoscope to check for damage. If there is damage inside the breathing valve, the breathing valve can be directly disassembled and repaired, which can greatly optimize the detection efficiency. After the endoscope is used, the endoscope is removed, and the used interface closing member 300 is reconnected to the endoscope interface 106 to block the endoscope interface 106.

[0045] The second pressure gauge installation interface 104 and the second pressure regulation interface 105 are arranged at 180 degrees with respect to the central axis of the tooling body 100.

[0046] The first pressure gauge installation interface 102 and the second pressure gauge installation interface 104 can be connected to an external pressure gauge. The attached drawing is a schematic diagram after connecting the pressure gauge. After installing the pressure gauge on the second pressure gauge installation interface 104, during the detection process, the staff can always observe whether the value of the pressure gauge connected to the second pressure gauge installation interface 104 is within the specified limit of the pressure vessel. If the displayed pressure exceeds the specified value limit, the staff needs to perform other operations to ensure that the pressure of the pressure vessel is within the specified limit.

[0047] During the test, the first pressure regulation interface 103 is connected to an external detection pipeline connector, and the detection pipeline connector is connected to an air intake / extraction device. Through the air intake / extraction device and the detection pipeline connector, air intake / exhaust operations can be performed on the breathing valve to detect the breathing valve.

[0048] The second pressure regulation interface 105 is connected to a pressure regulation component. The pressure regulation component can regulate the pressure inside the pressure vessel. In the non-detection state, the pressure regulation component is in the closed state. During the detection process, the staff always observes the value of the pressure gauge connected to the second pressure gauge installation interface 104. When the value of the pressure gauge exceeds the specified limit of the pressure vessel, the pressure regulation component is opened. When the pressure of the pressure vessel is greater than the upper limit of the specified limit, the pressure regulation component relieves the pressure of the pressure vessel; when the pressure of the pressure vessel is less than the lower limit of the specified limit, the pressure regulation component pressurizes the pressure vessel, thereby ensuring the safety of the detection.

[0049] During the detection process, if the pressure inside the pressure vessel fluctuates, the traditional blind plate sealing method cannot handle the pressure fluctuation of the pressure vessel in a timely manner, and it is easy to cause potential accident problems. This solution can detect the pressure inside the pressure vessel in real time during the detection process, and realize the exhaust or intake of the pressure vessel through the pressure regulation component, so as to ensure that the pressure in the tank is within the specified range and ensure the safety of the detection.

[0050] The plugging component 200 includes a medium injection channel 220 and an expansion plugging structure 210. The expansion plugging structure 210 is arranged in the plugging space 101, and the medium injection channel 220 is communicated with the expansion plugging structure 210. Specifically, in this embodiment, the expansion plugging structure 210 is a rubber component. Specifically, in this embodiment, the medium injection channel 220 is used to inject or extract gas into the expansion plugging structure 210, so that the expansion plugging structure 210 expands or contracts, thereby filling the plugging space 101 or canceling the filling of the plugging space 101.

[0051] When the expansion plugging structure 210 expands due to the injection of the medium and abuts against the two limiting and blocking nets 130 on both sides, the limiting and blocking nets 130 can restrict the expansion plugging structure 210 to prevent the expansion plugging structure 210 from leaving the plugging space 101 or over-expanding during expansion, thereby avoiding contact between the expansion plugging structure 210 and other components of the tooling body 100 and ensuring the normal operation of other components of the tooling body 100.

[0052] After the expansion plugging structure 210 abuts against multiple side walls of the plugging space 101 and the two limiting and blocking nets 130, the plugging of the plugging space 101 is completed, the injection of the medium is stopped, and the shape of the expansion plugging structure 210 is maintained to maintain the plugging of the plugging space 101, thereby ensuring the smooth progress of subsequent inspections.

[0053] Installing this new type of breather valve inlet tooling between the traditional breather valve and the pressure vessel can achieve the effect of rapid plugging by inflating the expansion plugging structure 210. Compared with plugging methods such as using solid blind plates, the plugging speed is greatly increased, which can effectively reduce the weight carried by the inspection personnel and thus improve the inspection efficiency.

[0054] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
