Description

Technical Field

[0001] This utility model relates to the field of fire equipment testing technology, specifically a moisture testing device for a heptafluoropropane extinguisher. Background Technology

[0002] Heptafluoropropane is widely used as a highly efficient and environmentally friendly fire extinguishing agent. To ensure its long-term stability and effectiveness, regular monitoring of the moisture content in heptafluoropropane fire extinguishers is crucial. Currently, the Karl Fischer coulometric method is the standard method for determining trace moisture. This method quantitatively analyzes the number of water molecules in a sample through a chemical reaction, and this precise measurement is typically performed using a trace moisture analyzer.

[0003] Currently, when using a trace moisture analyzer to test the moisture content of heptafluoropropane fire extinguishers, the electrolytic cell, as a core component, is used to promote the chemical reaction between the sample and the reagent. Since the electrolytic cell is usually installed on the instrument using a simple snap-fit ​​method, while this method is convenient for disassembly and cleaning, it has certain limitations in actual operation. First, during the moisture determination process, to ensure thorough mixing of the reagent and the sample, the liquid in the electrolytic cell needs to be stirred. However, this electrolytic cell installation structure does not provide sufficient stability and is prone to shaking during stirring, thus affecting the accuracy and repeatability of the measurement. Furthermore, the stirring process may cause stress concentration at the connection between the electrolytic cell and the instrument, which may lead to poor sealing or loosening of the interface after prolonged use, further increasing the risk of leakage. Utility Model Content

[0004] The purpose of this invention is to provide a moisture testing device for heptafluoropropane sterilizers, in order to solve the problems mentioned in the background art regarding the insufficient stability of the electrolytic cell installation of current trace moisture analyzers for heptafluoropropane sterilizers, the tendency to shake during stirring leading to poor measurement accuracy and repeatability, and the potential for poor sealing or loosening of interfaces after prolonged use, which increases the risk of leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heptafluoropropane sterilizer moisture testing device, comprising a trace moisture analyzer body, an electrolytic cell installed on one side of the top of the trace moisture analyzer body via a connection port, symmetrically distributed columns installed on both sides of the electrolytic cell, a controllable stabilizing component consisting of a support member and a clamping member installed at the lower end of the column, the controllable stabilizing component being fitted onto the column at a suitable height via a fixed sleeve ring, and an elastic clamping component provided at the top of the column, the elastic clamping component being used to clamp the two sides of the top interface of the electrolytic cell.

[0006] Preferably, the retaining ring is fixed in the middle of the outer side of the support member, and the clamping member is located on the inner side of the support member. A positioning member is provided in the gap between the support member and the clamping member, and the positioning member and the clamping member are connected by an elastic pad.

[0007] Preferably, adjusting bolts are inserted on both sides of the support member, and a pressure block is provided at one end of the adjusting bolt located on the inner side of the support member, and pressure grooves that match the structure of the pressure block are provided on both outer walls of the positioning member.

[0008] Preferably, the support member has a notch in the middle of its inner side, and the notch in the middle of the inner side of the support member is provided with a limiting spring that is connected to the middle of the outer side of the positioning member.

[0009] Preferably, the threaded ring is sleeved and connected to the outside of the top of the column through a threaded structure, the lower end of the flip-fastening member is movably connected to the outer wall of the threaded ring through a pivot pin, and the tension spring is connected between the outer side of the flip-fastening member and the outer wall of the threaded ring.

[0010] Preferably, the snap fastener has a right-angled structure, and a rubber pad is adhered and fixed to the inner wall of the snap fastener.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This heptafluoropropane sterilizer moisture testing device effectively reduces shaking and stress concentration during stirring by enhancing the stability and sealing of the electrolytic cell installation, thereby improving measurement accuracy and repeatability and reducing the risk of leakage. Through the design of the support and clamping components, the device achieves stable and appropriate clamping of the electrolytic cell, avoiding problems of over-clamping or under-clamping. Simultaneously, the fixed collar allows for convenient adjustment and fixation of the component height, ensuring the stability of the electrolytic cell in different application scenarios. Furthermore, the elastic clamping component at the top of the column further enhances the sealing at the top interface of the electrolytic cell, preventing any possible leakage problems caused by stirring.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a moisture testing device for a heptafluoropropane sterilizer, comprising a trace moisture analyzer body 1. A control panel and display screen are located on one side of the top of the trace moisture analyzer body 1. An electrolytic cell 2 is installed on the other side of the top of the trace moisture analyzer body 1 via a connection port. A collection tube is located on the top of the electrolytic cell 2, mainly used for connecting and transmitting gas samples to the electrolytic cell 2 for moisture content determination. Symmetrically distributed columns 3 are installed on both sides of the electrolytic cell 2. The bottom end of each column 3 is connected to a threaded interface on the trace moisture analyzer body 1, allowing for quick disassembly of the structure on the column 3 from the trace moisture analyzer body 1 when not in use. A controllable and stable support structure consisting of a support member 4 and a clamping member 5 is installed at the lower end of each column 3. The components, including the support 4 and clamping member 5, are all arc-shaped structures. This controllable and stabilizing component is mounted on the column 3 at a suitable height via a retaining ring 6. A locking bolt is connected to the retaining ring 6 via a threaded structure. The top of the column 3 is equipped with an elastic clamping component consisting of a threaded ring 7, a tension spring 8, and a flip-locking clamping member 9. This elastic clamping component is used to clamp both sides of the top interface of the electrolytic cell 2. When the main body 1 of this micro-moisture analyzer is used in conjunction with the electrolytic cell 2 to test the moisture content of the heptafluoropropane sterilizer, the two sides of the electrolytic cell 2 can be symmetrically positioned on both sides of the electrolytic cell 2 by installing the columns 3. The clamping member 5 can control the clamping force from the inside of the support 4, ensuring a stable and appropriate clamping force on the electrolytic cell 2. The pressure is adjusted to avoid over- or under-clamping, and the component is adjusted to the appropriate height and locked by the retaining ring 6, ensuring the stability of the electrolytic cell 2 during the test. Simultaneously, the top of the column 3 is fitted with an elastic clamping assembly consisting of a threaded ring 7, a tension spring 8, and a snap-fit ​​clamping component 9 to firmly press the two sides of the top interface of the electrolytic cell 2. This effectively reduces the shaking of the electrolytic cell 2 caused by stirring during operation, enhancing its stability and sealing, improving measurement accuracy and repeatability, and reducing the risk of leakage due to long-term use. This solves the problems of unstable and loose electrolytic cell installation structures in existing technologies, providing a more reliable operating platform for moisture testing of heptafluoropropane fire extinguishers. The clamping member 5 is welded and fixed to the middle of the outer side of the support member 4, and is located inside the support member 4. A positioning member 10 is provided in the gap between the support member 4 and the clamping member 5. The positioning member 10 and the clamping member 5 are connected by an elastic pad 11, which can be made of high-elasticity sponge material. The clamping member 5 with this structure can be adjusted in position as needed inside the support member 4 to accommodate electrolytic cells 2 of different sizes. At the same time, by adjusting the position of the positioning member 10, the clamping force of the clamping member 5 can be further fine-tuned to ensure that a stable and appropriate pressure is provided to the electrolytic cell 2. The elastic pad 11 is placed between the positioning member 10 and the clamping member 5, which can effectively buffer the stress generated during clamping, prevent excessive clamping from damaging the electrolytic cell 2, and also enhance the stability of clamping.Adjusting bolts 12 are inserted on both sides of the support member 4, and a pressure block 13 is provided at one end of the adjusting bolt 12 located inside the support member 4. The positioning member 10 is made of deformable elastic metal material, and pressure grooves matching the structure of the pressure block 13 are provided on both outer walls of the positioning member 10. This structure can be used to push the pressure block 13 inward by rotating the adjusting bolts 12. The pressure applied by the pressure block 13 is transmitted to the positioning member 10 through the matching pressure grooves. The positioning member 10 deforms under pressure, thereby causing the clamping member 5 to fit tightly against the outer contour of the electrolytic cell 2, providing additional The stability and adaptability not only allow for precise adjustments based on the specific size and shape of the electrolytic cell 2, but also ensure a uniform distribution of clamping force, avoiding damage caused by localized stress concentration. A notch is provided in the middle of the inner side of the support member 4, and a limiting spring 14 connected to the middle of the outer side of the positioning member 10 is located in this notch. This limiting spring 14 provides a reverse elastic force at the notch in the middle of the inner side of the support member 4, helping the positioning member 10 to smoothly respond to changes in external pressure and ensuring its flexible deformation according to actual needs. The threaded ring 7 passes through... A threaded structure is sleeved and connected to the outside of the top of the column 3. The outer wall of the top of the column 3 has a threaded structure. The lower end of the flip-fitting clamp 9 is movably connected to the outer wall of the threaded ring 7 through a pivot pin. The tension spring 8 is connected between the outer side of the flip-fitting clamp 9 and the outer wall of the threaded ring 7. The threaded ring 7 of this structure is firmly fixed to the top of the column 3 through its threaded structure, which not only provides a stable support point, but also allows the user to fine-tune its position according to actual needs. When it is necessary to firmly clamp the electrolytic cell 2, the flip-fitting clamp 9 is first flipped up around the pivot pin, so that the electrolytic cell 2 can be smoothly clamped. The clamp is placed on top of the column 3. Then, the flip-lock clamp 9 is released. Under the elastic force of the tension spring 8, the flip-lock clamp 9 will press tightly against both sides of the top interface of the electrolytic cell 2, ensuring its stability and preventing wobbling. The flip-lock clamp 9 has a right-angled structure, and a rubber pad is adhered and fixed to its inner wall. This structure allows the flip-lock clamp 9 to fit tightly against both sides of the top interface of the electrolytic cell 2. The rubber pad on the inner wall of the flip-lock clamp 9 contacts the surface of the electrolytic cell 2, not only increasing friction to ensure a stable clamping but also providing necessary cushioning to avoid potential damage from direct contact with hard materials.

[0018] Working Principle: When using this heptafluoropropane extinguisher moisture testing device, firstly, quickly connect the two columns 3 to the corresponding threaded interfaces on the main body 1 of the micro-moisture analyzer through their bottom threaded interfaces. Then, install the electrolytic cell 2 on one side of the top of the main body 1 of the micro-moisture analyzer through the connection port, ensuring that the collection tube at the top of the electrolytic cell 2 is correctly connected to transmit the gas sample to the inside of the electrolytic cell 2 for moisture content determination. Next, adjust the controllable and stable assembly consisting of the support 4 and the clamping 5 so that it is positioned at a suitable height on the column 3 through the fixed ring 6 and fixed by the locking bolt. At this time, rotate the adjusting bolt 12 to push the pressure block 13 inward, and apply pressure through the pressure block 13. Force is applied to the groove of the positioning part 10, causing the positioning part 10 to deform and drive the clamping part 5 to fit tightly against the outer contour of the electrolytic cell 2, providing additional stability and adaptability. Next, the position of the threaded ring 7 at the top of the column 3 is adjusted and it is firmly fixed by its threaded structure. It is also ensured that the flip-locking part 9 is movably connected to the outer wall of the threaded ring 7 by the pivot pin. The flip-locking part 9 is released, and under the elastic force of the tension spring 8, the flip-locking part 9 presses tightly against both sides of the top interface of the electrolytic cell 2. Finally, the parameters are set and the test program is started by operating the control panel and display screen on the top of the trace moisture analyzer body 1. The moisture in the heptafluoropropane fire extinguisher is accurately measured through the electrolytic cell 2, thereby completing a series of tasks.
