Among them,in residents of heating system, water collector manages a number of branchpipe and in air conditioning water system and industrial water system,management of the same number of branch pipeline, respectively include abackwater branch and water supply branch, but the large number ofDN350-DN1500 ranging, the use made of steel plate, which belongs to theprofessional class pressure vessel. A plurality of containers between the needto install a pressure regulating valve, and the need to automatically bypasspipeline auxiliary[2]. Visible in the production and life in many fields, hotwater collector showed its extraordinary role in reasonable Structure designand perfect processing flow, produced by the hot water collector moreassurance of industrial safety in production and the life convenient fortable[3]. So the catchment water heater structure design and processoptimization and innovation is particularly important. The design task is mainly according to the requirements of productionand processing, design and production of horizontal catchment water of horizontal catchment water heater is making process is simple,the installation is convenient, high safety coefficient. The hot water collectordes
