供热外管网与热用户的连接方式一般分为两种:间接连接和直接连接。其中间接连接比较常见的是在换热站或热用户入口处采用板式换热器换热机组进行热交换,这种方式需要建造专门的换热站机房,设备和土建方面投资比较大。直接连接又分为三种:
   There are two ways to connect the external heating pipe network and the heat users: indirect connection and direct connection. Among them, indirect connection is more common in the heat exchange station or at the entrance of the heat user to use plate heat exchanger heat exchange unit for heat exchange. This way requires the construction of a special heat exchange station room, with large investment in equipment and civil engineering. There are three types of direct connections:
    1无混合装置连接,即外网的热水直接进入到供热系统再输送到用户家里,这种适用于小的供热系统,应用条件受限制;
    1. There is no mixing device connection, that is, the hot water from the external network directly enters the heating system and then is delivered to the user's home, which is suitable for small heating system, and the application conditions are limited;
    2装水喷射器的直接连接,这种方式构造简单,但要求供回水之间有一定的压差;
 Direct connection of water injector, which is simple in structure, but requires a certain pressure difference between water supply and return;
    3装混合水泵的直接连接,这种形式需要增加混合水泵,会消耗一定的电能。随着变频水泵的普及应用,这种方式的优势正在显现,目前国内已经有很多供热系统采用这种连接方式。混合水泵的直接连接也叫做混水系统。
The direct connection of the mixing water pump needs to increase the mixing water pump, which will consume a certain amount of electric energy. With the popularization and application of variable frequency water pump, the advantages of this method are emerging. At present, there are many heating systems in China that adopt this connection method. The direct connection of the mixing pump is also called the mixing system.
    混水系统的原理:混水系统一般设置在各建筑单元热力入口的地下室里,其原理是把从用户端出来的回水通过混水旁通管与从供热外网来的二次供水进行混合。液位变送器应用:分布式混水机组供热方式和传统供热系统
Principle of the mixed water system: the mixed water system is generally set in the basement of the thermal entrance of each building unit. Its principle is to mix the return water from the user end with the secondary water supply from the external heating network through the mixed water bypass pipe. Application of liquid level transmitter: heating mode of distributed mixed water unit and traditional heating system
