一、引言 球形补偿器是热力管网中解决管道热膨胀的一种新型装置。国外一些发达国家如美国、日本、法国等之所以广泛使用,除因为球形补偿器具有补偿能力大,流体阻力和变形应力小,能节省材料和节约投资,占地少、按装方便等优点外,它还具有一个显著的优点——节能。特别是在世界能源日趋紧张的今天,这就更加显示出球形补偿器的生命力和优越性。因此,广泛推广使用球形补偿器已势在必行。 在我国,球形补偿器的使用价值还没有被人们充分认识。只取其补偿能力大,节省材料及节约投资的优点,而没有或很少从节省
I. INTRODUCTION The spherical compensator is a new type of device that solves the thermal expansion of the pipe in the heat pipe network. The reason why some developed countries abroad, such as the United States, Japan, and France, are widely used, except that the spherical compensators have large compensation capability, low fluid resistance and deformation stress, can save materials and save investment, and occupy less land and are easier to install. It also has a significant advantage - energy savings. Especially in today’s increasingly tense world of energy, this shows even more the vitality and superiority of spherical compensators. Therefore, it is imperative to widely promote the use of spherical compensators. In China, the use value of spherical compensators has not been fully understood. Only take advantage of its large compensation capacity, material savings and investment savings, and no or very little from the savings
