Description
本新型是有關於一種接頭裝置,特別是指一種用於管路及設備安裝的接頭裝置。The present invention relates to a joint device, and more particularly to a joint device for piping and equipment installation.
管路的設置在於提供各種流體(例如:液體、氣體)傳輸的路徑,而管路中所連接設置的各種接頭裝置,主要在防止管路因溫度變化產生熱脹冷縮,導致彎曲或斷裂,而發生流體外洩的狀況,如管路所傳送的為液化石油氣、有毒化學液體、高壓氣體等具有危險性的流體,外洩的狀況就會造成環境汙染、氣爆或有毒氣體擴散等危險。另外,接頭裝置如裝設於引擎、壓縮機等環境,也會因長久的機械振動而產生管路伸縮、搖晃的現象,因此接頭裝置也必須具有吸收振動的能力,以緩衝振動造成的變形或位移變化。再者,接頭裝置與管路安裝連接時的密合程度也相當重要,如密合程度不佳產生縫隙同樣有可能會發生流體洩漏的情況。故管路中所裝設的接頭裝置對於整體管路的設置,具有舉足輕重的重要地位。The pipeline is arranged to provide a path for the transmission of various fluids (for example, liquids, gases), and the various joint devices provided in the pipelines mainly prevent the pipeline from being thermally expanded and contracted due to temperature changes, resulting in bending or breaking, In the case of fluid leakage, such as liquefied petroleum gas, toxic chemical liquid, high-pressure gas and other dangerous fluids, the leakage will cause environmental pollution, gas explosion or toxic gas diffusion. . In addition, if the joint device is installed in an environment such as an engine or a compressor, the pipe may be stretched and shaken due to long-term mechanical vibration. Therefore, the joint device must also have the ability to absorb vibration to compensate for vibration or deformation. Displacement changes. Furthermore, the degree of adhesion of the joint device to the pipe is also important. If the degree of tightness is not good, the gap may also cause fluid leakage. Therefore, the joint device installed in the pipeline plays an important role in the setting of the overall pipeline.
