In the pharmaceutical industry, pure steam (clean steam) is typically used for cleanroom air conditioning humidification, heat sterilization, or sterilization processes. Pure steam must be free of volatile additives to prevent contamination of pharmaceuticals. For steam used in sterilization, the steam quality—superheat, dryness fraction, and non-condensable gas content—must be tested and monitored, and must meet the requirements of British Standard EN285.

Detailed Implementation

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application 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 application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] When using a quick-connect superheat detection device to test different steam pressures, it is necessary to replace the center tube with one of different diameters, which means that the center tube and expansion tube need to be disassembled. In related technologies, the center tube and expansion tube are generally connected by a threaded connection. However, due to the high temperature and pressure of the steam, threaded connections suffer from unreliability and inconvenience.

[0037] Based on this, one embodiment of this application provides a quick-assembly superheat detection device that can solve the above-mentioned technical problems. The quick-assembly superheat detection device provided in one embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0038] See Figures 1 to 3 As shown, an embodiment of this application provides a quick-install superheat detection device, including a central tube 100, a first sealing gasket 200, and an expansion tube 300. The central tube 100 has a steam inlet 110 and a steam outlet 120. The outer peripheral wall of the central tube 100 is constructed with a first perforated plate 130. The first sealing gasket 200 is sleeved on the outer peripheral wall of the central tube 100, and the first sealing gasket 200 is snapped into the first perforated plate 130. The expansion tube 300 is sleeved on the outer peripheral wall of the first sealing gasket 200 and is located at the end of the first sealing gasket 200 away from the central tube 100. The expansion tube 300 is provided with a temperature detection interface 310, which is connected to a temperature detection module 400 and communicates with the steam outlet 120. It can be understood that the diameter of the steam outlet 120 is much smaller than the diameter of the steam inlet 110.

[0039] The aforementioned quick-installation superheat detection device improves the tightness and stability of the connection between the central tube 100 and the expansion tube 300 by fitting a sealing gasket between them, reducing the risk of steam leakage and ejection from the interface, and allowing for more precise temperature detection positioning. Simultaneously, since the first sealing gasket 200 is mated with the first orifice plate 130, the first orifice plate 130 also serves as an installation limit for the first sealing gasket 200, improving the reliability and stability of the connection between components. Furthermore, the snap-fit ​​connection between the components makes installation more convenient, improving assembly efficiency and reducing assembly difficulty. Understandably, the inner diameter of the central tube 100 can be designed with various orifice diameters according to EN285 requirements to adapt to actual usage needs for measuring different steam pressures.

[0040] See Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment, the first sealing gasket 200 is provided with a first sealing groove 210 recessed along its own axial direction, and the first perforated plate 130 engages with the first sealing groove 210. Understandably, the outer diameter of the first perforated plate 130 matches the diameter of the first sealing groove 210, resulting in a tighter connection between the two, thereby improving the sealing effect of the central tube 100 and the expansion tube 300 and reducing the possibility of vapor leakage. In addition to its sealing function, the first sealing gasket 200 also provides heat insulation, reducing the risk of burns to analytical personnel.

[0041] See Figures 3 to 4 As shown, in one embodiment, one of the first sealing gasket 200 and the expansion tube 300 is provided with a first snap-fit ​​portion 220, and the other of the first sealing gasket 200 and the expansion tube 300 is provided with a first mating portion. The first snap-fit ​​portion 220 engages with the first mating portion. Through the snap-fit ​​engagement of the first snap-fit ​​portion 220 and the first mating portion, on the one hand, quick snap-fitting of the first sealing gasket 200 and the expansion tube 300 can be achieved, and on the other hand, the snap-fitting effect of the first sealing gasket 200 and the expansion tube 300 can be improved, thereby enhancing the reliability of the device.

[0042] See Figures 3 to 4 As shown, in one embodiment, the first engaging portion 220 is configured as a first annular protrusion 221, which is formed on the first sealing gasket 200; the first mating portion is configured as a first annular groove for engaging with the first annular protrusion 221, which is formed on the expansion tube 300. Of course, in other embodiments, the positions of the first annular protrusion 221 and the first annular groove can be interchanged, that is, the expansion tube 300 is configured with the first annular protrusion 221, and the first sealing gasket 200 is configured with the first annular groove.

[0043] In one embodiment, the quick-install superheat detection device further includes a first clamp, which has a first groove for engaging the first orifice plate 130 and the expansion tube 300. The first clamp secures the central tube 100 and the expansion tube 300, improving the tightness of the connection and further reducing the risk of steam leakage.

[0044] See Figure 2As shown, in one embodiment, the temperature detection interface 310 extends radially along the expansion tube 300; the probe end 410 of the temperature detection module 400 passes through the temperature detection interface 310 and also through the expansion cavity of the expansion tube 300. By extending the probe end 410 of the temperature detection module 400 into the expansion cavity of the expansion tube 300, the probe end 410 is in direct contact with the steam, improving detection accuracy. The temperature difference between the temperature measured by the temperature detection module 400 and the temperature of saturated steam at the same atmospheric pressure is the superheat of the steam. By setting the temperature detection interface 310 on the radial side of the expansion tube 300, other interfaces, such as the dryness detection interface 330, can be set on the axial side of the expansion tube 300, thereby enabling simultaneous dryness detection. In one embodiment, the temperature detection module 400 can specifically be a temperature sensor.

[0045] In one embodiment, the expansion tube 300 and the central tube 100 can be made of metal, such as stainless steel. The first sealing gasket 200 can be made of a flexible material, such as rubber.

[0046] See Figure 2 As shown, in one embodiment, the quick-install superheat detection device further includes a second sealing gasket 420, which is connected between the temperature detection interface 310 and the temperature detection module 400. By providing the second sealing gasket 420, the sealing effect between the temperature detection interface 310 and the temperature detection module 400 is further improved, reducing the risk of steam leakage and improving the accuracy of the detection results.

[0047] See Figure 2 As shown, in one embodiment, the second sealing gasket 420 is configured with a second snap-fit ​​portion 421, and the temperature detection module 400 is configured with a second mating portion 401 for snapping with the second snap-fit ​​portion 421. One of the second snap-fit ​​portion 421 and the second mating portion 401 is configured as a second annular protrusion, and the other is configured as a second annular groove. The snap-fit ​​engagement of the second annular protrusion and the second annular groove improves the ease of connection between the temperature detection module 400 and the temperature detection interface 310, and also enhances the sealing effect between them. For example, in... Figure 2 In the illustrated embodiment, the second sealing gasket 420 is configured with a second annular protrusion, and the temperature detection module 400 is configured with a second annular groove. In other embodiments, the second sealing gasket 420 may be configured with a second annular groove, and the temperature detection module 400 may be configured with a second annular protrusion.

[0048] See Figure 2As shown, the quick-install superheat detection device also includes a second clamp 430, which has a second slot for engaging the temperature detection interface 310 and the temperature detection module 400. The second clamp 430 securely fastens the temperature detection interface 310 and the temperature detection module 400, improving the tightness of the connection and further reducing the risk of steam leakage, thus enhancing the reliability of superheat detection. The second clamp 430 can be a bolt-type clamp, including two connecting parts. These two connecting parts are fitted onto the outer walls of the temperature detection module 400 and the temperature detection interface 310, and pressure is applied by bolts to firmly press the two connecting parts together.

[0049] See Figure 2 As shown, in one embodiment, the end of the expansion tube 300 furthest from the central tube 100 is provided with a dryness detection interface 330, which is used to connect to the dryness detection module 340. Since the dryness detection interface 330 is integrated at the end of the expansion tube 300 (the end furthest from the central tube 100), connecting to the dryness detection module 340 through the dryness detection interface 330 allows for simultaneous detection of superheat and dryness, improving the efficiency of steam quality detection. For example, in... Figure 2 In the illustrated embodiment, the dryness detection interface 330 is connected to a flexible hose, which can be connected to a vacuum bottle, through which steam enters the vacuum bottle. By detecting the weight of the vacuum bottle and the temperature of the water before and after the introduction of steam, the steam dryness value can be calculated.

[0050] See Figure 2 As shown, in one embodiment, a third sealing gasket 360 is provided between the dryness detection interface 330 and the dryness detection module 340. The third sealing gasket 360 improves the sealing effect between the dryness detection interface 330 and the dryness detection module 340, reducing the risk of vapor leakage. One of the third sealing gasket 360 and the dryness detection module 340 may be constructed with a third annular protrusion 361, and the other may be constructed with a third annular groove for engaging with the third annular protrusion 361. The engaging cooperation between the third annular protrusion 361 and the third annular groove improves the ease of connection between the dryness detection module 340 and the dryness detection interface 330, and also enhances the sealing effect between them. For example, in... Figure 2 In the illustrated embodiment, the third sealing gasket 360 is configured with a third annular protrusion 361, and the dryness detection module 340 is configured with a third annular groove. In other embodiments, the third sealing gasket 360 may be configured with a third annular groove, and the dryness detection module 340 may be configured with a third annular protrusion 361.

[0051] See Figure 2As shown, the quick-install superheat detection device also includes a third clamp 350, which has a third slot for engaging the dryness detection interface 330 and the dryness detection module 340. The third clamp 350 securely locks the dryness detection interface 330 and the dryness detection module 340 together, improving the tightness of the connection, further reducing the risk of steam leakage, and enhancing the reliability of dryness detection. The structure of the third clamp 350 can be referenced from the structure of the second clamp 430, and will not be described further here.

[0052] 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.

[0053] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
