Description

流體連接器 Fluid connector

本創作係有關一種公、母接頭對接前後及過程，不易有流體外洩、外漏或外滲的流體連接器。 This creation is about a kind of fluid connector before and after the butting of male and female joints and the process, which is not easy to leak, leak or seep.

按，加壓端上游流體往低壓端下游輸送，常在輸送路徑(如輸送管)與接收路徑(如接收管)上裝設連接器，使輸送路徑與接收路徑之間可選擇性的連通或斷開。 Press, the fluid from the upstream of the pressurizing end is transported to the downstream of the low-pressure end. Connectors are often installed on the transport path (such as the transport pipe) and the receiving path (such as the receiving pipe), so that the transport path and the receiving path can be selectively connected or connected. disconnect.

市面上連接器，一般包含有一公接頭及一母接頭，其對接前後或過程，通常必須在關閉上游流體輸出的型態下進行，否則公、母接頭的對接口會排出流體；儘管公、母接頭欲離開時，可由上游的開關閥關閉流體送出，唯輸送路徑(管路)或接收路徑所殘留下來的流體，仍會從公接頭及/或母接頭的接口外漏出來，污染或影響環境。 Connectors on the market generally include a male connector and a female connector. Before and after the docking or the process, usually must be done in the mode of shutting off the upstream fluid output, otherwise the mating interface of the male and female connectors will discharge fluid; although the male and female connectors When the connector wants to leave, the upstream switch valve can be used to close the fluid delivery. Only the remaining fluid in the delivery path (pipeline) or receiving path will still leak from the male connector and/or female connector interface, polluting or affecting the environment .

習用如TWI427231及TWI463089號台灣發明專利，為一種連接器或耦接器，皆是在公、母接頭內設閥件，當公、母接頭對接時打開閥門連通上下游流體，反之，則關閉閥門，限制上游流體輸出；其雖能省略上游開關閥的使用，唯，公、母接頭內閥件(閥門)至對接頭存在有一段距離，以致公、母接頭完全脫離的過程，接頭內會因仍然殘留下有些許流體，而難以避免對接口處不會有流體滴出的情形。 Traditionally used, such as TWI427231 and TWI463089 Taiwan Invention Patent, is a connector or coupler, both of which are equipped with valves in the male and female joints. When the male and female joints are connected, the valve is opened to connect the upstream and downstream fluids, and vice versa, the valve is closed. , Limiting the upstream fluid output; although it can omit the use of upstream switching valves, but there is a certain distance between the valve parts (valves) in the male and female joints and the counter joint, so that the male and female joints are completely separated from each other. There is still a little fluid remaining, and it is difficult to avoid the situation that no fluid drips out of the interface.
