[0002] With the continuous development of modern buildings and industrial systems, pipeline systems are increasingly widely used in the transportation of water, gas and other fluids. In these pipeline systems, pressure sensors are widely used to monitor and control the pressure of the fluid to ensure the normal operation and safety of the system. However, during the installation of the pressure sensor, especially at the installation pipe fitting connected with the water pipe, sealing problems are often encountered.

[0003] Usually, the pressure sensor is connected with the water pipe through the installation pipe fitting, and in order to ensure the sealing of the connection, a rubber sealing ring is usually provided on the side wall of the installation pipe fitting. When the pressure sensor or the pipe fitting is tightened, the rubber sealing ring is deformed by extrusion to achieve sealing of the water pipe. However, in actual operation, the rubber sealing ring is easily affected by the circumferential rotating force during installation. This rotating force is usually generated when the installation pipe fitting is tightened, especially when a larger torque is applied.

[0004] Due to the good elasticity and toughness of the rubber material, it is easy to tear or damage in the case of frequent changes in the direction of force. Such damage not only leads to sealing failure, thereby causing leakage problems, but also may adversely affect the safety and reliability of the entire pipeline system.

[0005] Therefore, how to effectively prevent the rubber sealing ring from tearing due to the circumferential rotating force during installation has become a problem to be solved in the design of pressure sensors and their installation pipe fittings. It is of great practical significance to develop a new structure that can ensure sealing while effectively reducing or avoiding damage to the rubber sealing ring by circumferential rotating force.

[0028] 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.

[0029] A pressure sensor mounting structure and a pressure sensor, such as Figures 1-4 As shown, the device includes a base 1, within which a pressure sensor assembly is housed. A connecting pipe 6 is integrally formed at the bottom of the base 1, with external threads on its outer wall for easy connection to a water pipe. At the junction of the connecting pipe 6 and the base 1, from top to bottom, are an upper sealing ring 7, a sealing ring 8, and a lower sealing ring 9, where the sealing ring 8 is a rubber ring, and the upper sealing ring 7 and sealing ring 8 are metal rings. The upper sealing ring 7 is fixedly connected to the connecting pipe 6. A guide groove 10 is formed on the connecting pipe 6 corresponding to the position of the lower sealing ring 9; the guide groove 10 is a circumferential inclined groove. A guide block 11 is integrally formed on the lower sealing ring 9 corresponding to the position of the guide groove 10. Furthermore, the inclined direction of the guide groove 10... With the same external thread direction as the connecting pipe 6, during installation, the connecting pipe 6 is tightened to the water pipe. During the tightening process, the water pipe presses against the lower sealing ring 9, causing the lower sealing ring 9 to move axially along the connecting pipe 6, gradually squeezing the sealing ring 8, so that the upper sealing ring 7, sealing ring 8 and lower sealing ring 9 are interference fit, and the inner side of the sealing ring 8 also squeezes the surface of the connecting pipe 6, thereby making the installation more airtight. Because the opening angle of the guide groove 10 is the same as the external thread direction in this embodiment, the lower sealing ring 9 does not move relative to the sealing ring 8 in the final tightening stage, reducing tearing of the sealing ring 8, not damaging the sealing ring 8, and ensuring that the sealing ring 8 can successfully seal the water pipe.

[0030] In some embodiments, the outer ring of the upper sealing ring 7 is an inclined surface, and the inner ring of the lower sealing ring 9 is an inclined surface that cooperates with the upper sealing ring 7. The inclined surface guides the sealing ring 8 to seal more tightly.

[0031] In other embodiments, the inner ring of the upper sealing ring 7 is an inclined surface, and the inner ring of the lower sealing ring 9 is also an inclined surface. The inclined surfaces of the upper sealing ring 7 and the lower sealing ring 9 form a sealing space for the compression sealing ring 8 near the connecting pipe 6.

[0032] In this embodiment, the pressure sensor assembly includes a pressure sensing component 3, a battery 4, and a communication component 5. The pressure sensing component 3 is fixed to the bottom of the base 1 with adhesive, the battery 4 is fixed to the middle of the base 1, and the communication component 5 is fixedly installed on the top of the base 1 for easy signal transmission. In some embodiments, the communication component 5 is an Internet of Things (IoT) module that can remotely connect to the network for pressure monitoring. In other embodiments, the communication component 5 is an NFC module or a Bluetooth module that can transmit data and obtain pressure data at close range through a handheld device such as a mobile phone.

[0033] Furthermore, the bottom of the base 1 is integrally formed with a support plate 12. The support plate 12 consists of multiple sets of fan-shaped blocks evenly spaced around the connecting pipe 6. The pressure sensing component 3 is attached to the support plate 12. During the potting and sealing process, the glue can fix the pressure sensing component 3 from the top and bottom sides.

[0034] Furthermore, the base 1 is provided with multiple sets of glue grooves 13 at the position below the support plate 12. The glue grooves 13 are circular grooves with a convex cross-section. When the glue passes through the glue grooves 13, it seeps into the glue grooves 13 and increases the tightness after solidification. The base 1 is also provided with glue guide grooves 14 at the position of the connecting pipe 6, so that more glue is gathered at the position of the connecting pipe 6. After the pressure sensor of the pressure sensing component 3 is aligned with the connecting pipe 6, the glue enhances the sealing between the pressure sensing component 3 and the connecting pipe 6.

[0035] Furthermore, a top cover 2 is detachably installed on the top of the base 1, and an observation slot 15 is fixedly installed at the center of the top of the top cover 2. The internal condition of the base 1 can be observed through the observation slot 15. In some cases, the communication component 5 can be set to display the pressure value in real time.

[0036] The working principle of this utility model is as follows: During installation, the connecting pipe 6 is tightened with the water pipe. During the tightening process, the water pipe presses against the lower sealing ring 9, causing the lower sealing ring 9 to move axially along the connecting pipe 6, gradually squeezing the sealing ring 8, so that the upper sealing ring 7, the sealing ring 8 and the lower sealing ring 9 are interference-fitted. In addition, the inner side of the sealing ring 8 also squeezes the surface of the connecting pipe 6, thereby making the installation more airtight. In this embodiment, the opening angle of the guide groove 10 is the same as the direction of the external thread. Therefore, when the lower sealing ring 9 is finally tightened, its position relative to the sealing ring 8 does not move, reducing tearing of the sealing ring 8, not damaging the sealing ring 8, and ensuring that the sealing ring 8 can successfully seal the water pipe.

[0037] When the glue passes through the glue tank 13, it seeps into the glue tank 13 and increases the tightness after solidification. The base 1 is also provided with a glue guide groove 14 corresponding to the position of the connecting pipe 6, so that more glue is gathered at the position of the connecting pipe 6. After the pressure sensor of the pressure sensing component 3 is aligned with the connecting pipe 6, the glue enhances the sealing between the pressure sensing component 3 and the connecting pipe 6.

[0038] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
