Abstract

The invention provides a hot water pipe network system, relating to a pipe network system, which aims at solving the problem that in the conventional pipe network system, trapping is performed by a valve or a trapping hole plate, energy is wasted regarding a primary network, while a water pump is required to reduce resistance loss regarding a secondary network. The system comprises two schemes, wherein one scheme is that: the input end of a hydraulic turbine is connected with a primary water supply pipe, while the output end is connected with a first connecting shaft; the hydraulic turbine isconnected with a circulating pump through a first connecting shaft, a coupling and a second connecting shaft; the circulating pump is connected with a water device; and the outlet of the hydraulic turbine is connected with a heat exchanger; and the water inlet of the circulating pump is connected with the heat exchanger; and the other scheme is that: the input end of the hydraulic turbine is connected with a primary water supply pipe, while the output end is connected with a first connecting shaft; the hydraulic turbine is connected with a circulating pump through a first coupling, a couplingand a second coupling; the circulating pump is connected with a water device; and the hydraulic turbine and the water inlet of the circulating pump are connected with a water outlet of a bypass pipe through the same pipeline. The hot water pipe network system is used in a pipe network system between a boiler and a hot water user.

Description

technical field [0001] The invention relates to a pipe network system. Background technique [0002] The heating network is a pipeline system used to transport and distribute hot water under the condition of central heating. It is composed of two parts of the pipeline system: the water supply pipe and the return pipe. The water in the water pipe has a small flow rate and a large temperature difference. For hot water users, in order to achieve a better heating effect, a large flow rate and a small temperature difference are required. The temperature is inconsistent. In order to solve the above problems, it is necessary to set up a heat exchanger or a bypass pipe between the boiler room and the heat user for heat exchange: such as Figure 7 Shown, is to utilize heat exchanger 13 to carry out heat exchange; As Figure 8 As shown, the bypass pipe 20 is used for heat exchange. In a complex pipe network system, due to the existence of multiple heat users, a water pump is unifor...
