AI Technical Summary
Existing systems fail to detect and prevent faulty connections, incomplete couplings, or damaged seals in fluid-carrying lines, leading to potential leaks and pressure loss, especially in high and low-pressure applications.
A system for detecting and monitoring the sealing condition of couplings using mechanical, electrical, or hybrid elements that record force, displacement, or pressure, with optical, acoustic, or digital signal transmission, suitable for integration into existing couplings or as a retrofittable add-on module.
Prevents dangerous situations by detecting faulty connections early, reducing maintenance complexity and ensuring secure fluid transfer.
Abstract
Description
[0001] The invention relates to a system for detecting and monitoring the sealing condition of plug, screw or bayonet couplings in fluid-carrying lines, particularly in high and low pressure applications for liquid or gaseous media.
[0002] The system is designed to automatically detect and indicate faulty connections, incompletely locked couplings, or damaged seals before a loss of pressure, leakage, or unintentional disconnection of the connection occurs.
[0003] The system can be mechanical, electrical, sensory, or hybrid and includes at least one detection element that records the force, displacement, or pressure at the connection. The signal can be transmitted via an optical, acoustic, or digital interface.
[0004] The aim is to prevent dangerous situations such as incomplete connections, pressure loss or media leakage at an early stage, while also making maintenance easier.
[0005] The system can be integrated into all types of couplings or implemented as a retrofittable add-on module. This makes it suitable for fire service couplings (Storz systems), hydraulic and pneumatic connections, piping systems in construction, agricultural or industrial plants, as well as applications in the chemical and energy sectors.
Claims

[4] System according to any one of the preceding claims, characterized bythat the detection element is designed as a module integrated into the seal, as an additional ring or as an external adapter that can be retrofitted into existing coupling systems. [5] System according to any one of the preceding claims, characterized by that it is suitable for liquid and gaseous media and can be used in areas with operating pressures from 0 to over 600 bar. [6] System according to any one of the preceding claims, characterized by , that if a misalignment is detected, the media flow is automatically throttled, interrupted or blocked. [7] System according to any one of the preceding claims, characterized by that it can be used in fire hose couplings, hydraulic systems, pneumatic, chemical, energy, construction and agricultural systems. 1
