Description

The invention relates to an interchangeable holder for throttle valves of various sizes in a fluid-carrying system, a fluid-carrying system, and a vehicle. Throttle valves and their use in fluid-carrying systems for changing the flow resistance and thus for controlling and regulating the flow of a fluid are well known. Currently, throttle valves are primarily used in hoses so that, in the event of a change, only the affected throttle valve can be replaced. Installation in the same hose using a pressure press is then possible. When a throttle valve is used in an assembly or in a single plastic component, replacing the throttle valve also means changing or replacing the tool, if not the entire hose. This is complex and costly. The US 11,112,808 B2 describes a flow restrictor for liquids, in which a throttle valve is inserted into the connection area of two pipe sections and held in place by means of a sleeve. The DE 198 33 899 C2 This describes a combined component consisting of a throttle valve and a check valve, which is inserted into a flexible hose and secured by an external retaining clip. The check valve can be clipped into the throttle valve or attached to it using a snap-fit connection. As a further state of the art, reference is also made to the EP 0 509 344 B1 referred. The object of the invention is to provide an alternative fastening option for throttle valves in fluid-carrying systems, as well as a fluid-carrying system and vehicle. The problem is solved by a changeable holder with the features of claim 1, by a fluid-guiding system with the features of claim 5, and by a vehicle with the features of claim 10. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims. The interchangeable holder according to the invention for throttle valves of various sizes in a fluid-carrying system, particularly in a vehicle, is designed such that it can be removed from the system and the throttle valves can be exchanged when removed. Various throttle valves can be used in the system with the interchangeable holder according to the invention. Advantageously, only the interchangeable holder is removed from the system for replacement and then reinserted. Within the scope of the invention, the term "throttle valve" is understood as a generic term for any components that alter flow resistance, for example, valves, capillaries, nozzles, or orifices. The fluid-carrying system can contain both water and air. Furthermore, the interchangeable holder according to the invention can advantageously be used in hoses made of a flexible material as well as in pipes made of a harder and inflexible material such as hard plastic, polymer, or similar materials. For the sake of simplicity, the term "hose" will be used uniformly in the following, and this term is not to be understood restrictively, but also includes pipes. It is provided that fastening means are designed for securing the interchangeable holder in a hose of the fluid-carrying system. Preferably, the fastening of the interchangeable holder can be released and re-secured without tools. Therefore, the fastening means are preferably operable without tools for securing and releasing the interchangeable holder in the hose. Furthermore, preferably, the interchangeable holder is arranged in an end region, in particular a hose fitting, or another easily accessible area of the fluid-carrying system. The fastening means can be designed, for example, as an external thread for screwing the quick-release holder into the hose and/or as a frictional locking element to create a frictional connection between the quick-release holder and the hose. For a frictional connection between the quick-release holder and the hose, the contact surfaces between these components are advantageously designed to be frictionally tight or rough. For example, the quick-release holder may have serrations or other irregularities, or a coating with a particularly high-friction material. The aforementioned list of fastening means is not exhaustive. Other types of fastening means and configurations of the fastening are also within the scope of the invention. It is further provided that holding/exchange means are present and designed to hold the throttle valves in the exchangeable holder, which also enable easy exchange of the throttle valves in the exchangeable holder. According to the invention, the exchangeable holder is compatible with throttle valves of various sizes. Preferably, the exchangeable holder has holding/exchange means that allow for simple, quick, and preferably tool-free exchange. The retaining/replacement devices enable the easy removal and replacement of the throttle valves and, secondly, ensure the secure attachment of the respective throttle valve in the interchangeable holder. For example, the retaining/replacement devices can be designed as a simple clip system, a bayonet fitting, or similar. Throttle valves of different sizes usua
