[0002] Water for injection is a common liquid used by pharmaceutical enterprises, which is usually transported to various water points through a delivery pipeline system. The existing delivery pipeline is provided with only one water supply pipeline, but the temperature of water for injection required by different water points is different (divided into high temperature and low temperature), which will cause the pipeline to be longer when the number of water points is large, and a large number of heat exchangers also need to be used (to ensure the use requirements of the water points). Therefore, the construction cost and maintenance cost of the pipeline are relatively high, and the later maintenance is also relatively inconvenient. CONTENT OF THE UTILITY MODEL

[0012] Preferably, the third pipeline is provided with a plurality of the first water points.

[0013] Preferably, the second circulation pipeline comprises a fourth pipeline, the low-temperature pipeline and a fifth pipeline which are sequentially communicated.

[0014] Preferably, the low-temperature pipeline is communicated with the fourth pipeline and the fifth pipeline through corresponding heat exchangers at two ends thereof.

[0015] Preferably, the fourth pipeline is communicated with the liquid outlet end of the first pipeline and the liquid inlet end of the second pipeline away from the liquid inlet end of the low-temperature pipeline; and the liquid outlet end of the fifth pipeline is directly communicated with the storage tank.

Further, the description should not be interpreted as implying that any particular element, feature, structure, or characteristic is essential.

[0025] Throughout the specification, when an element (such as a layer, region, or substrate) is referred to as being "on" another element, "connected to" another element, "coupled to" another element, "adjacent to" another element, or "covering" another element, it can be directly on, connected, coupled, adjacent to, or covering the other element, or one or more other elements can be interposed therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to," "directly coupled to," "directly adjacent to," or "directly covering" another element, there are no other elements interposed therebetween.

[0026] As used herein, the term "and / or" includes any one of the listed items and any combination of two or more of the listed items.
