Problems solved by technology

Since the crossover valve and the three-way flow proportional distribution cut-off valve used in this technical solution are manually operated valves, it is impossible to control the indoor temperature of existing users. At the same time, the pipeline is relatively complicated, and the valves and other devices used are many and the cost is high.

Embodiment 1

[0036] Example 1: As shown in Figure 1, the new single-pipe system is a centralized heating single-pipe heat distribution household metering management network system, and heating branch pipe 11 is set on the n+1 layer of the heating area n+1 , Set the return pipe 2 at its lower level; the heating branch pipe 11 of the n+1 layer n+1 ,Connect the heating load A of this floor n+1 , By the heating load A n+1 Backwater branch pipe 21 n+1 Connecting to the heating load A of the next floor n , Heating from top to bottom in turn, until the heating load A of the first layer 1 Backwater branch pipe 21 1 It is connected with the return pipe 2 at the lower level, and a remote flow meter 6 is installed on the heating main pipe 1. 总 And inlet water temperature sensor 7 总 , And there is an intelligent electric two-way flow proportional distribution stop valve 31 on the return pipe 2 总 And return water temperature sensor 7 h The control output terminal is connected to the master acquisition cont...

Embodiment 2

[0040] Example 2: See figure 2 , A new single-pipe system, the computer monitoring system 5 includes a regional heat distribution center computer platform 51 connected to multiple communities and a single building embedded real-time monitoring summary table 52, and its output is connected to multiple unit embedded real-time monitors 53, The output terminal of the embedded unit real-time monitor 53 is connected to the household acquisition controller 4 n . The rest of the structure is the same as the above example. There are also valves in the heating network.

Embodiment 3

[0042] Example 3: See image 3 , The centralized heating single-tube heat distribution household metering and charging management network system for the transformation of the single-tube old system, including the setting of heating branch pipes 11 in the n+1 layer of the heating area n+1 ,Set the return pipe 2 at its lower level, which consists of n+1 layer heating branch pipes 11 n+1 ,Connect the heating load A of this floor n+1 . The load of the old single-tube system is the load of each room and the load of each heating load A n+1 Backwater branch pipe 21 n+1 Connect to the corresponding indoor heating load A of the next floor n , Heating from top to bottom in turn, until the heating load A of the first layer 1 Backwater branch pipe 21 1 It is connected with the return pipe 2 at the lower level, and a remote flow meter 6 is installed on the heating main pipe 1. 总 And inlet water temperature sensor 7 总 And there is an intelligent electric two-way flow adjustment shut-off valve 3...

Abstract

The present invention relates to central heating supply and separated metering system. The single-pipe heat distribution separating management network system for central heating includes heating supply branch pipes, lower story return pipe in the heating supply area; and the heating supply loads in different stories connected through return branch pipes. It features the remote flowmeter and main inflow water temperature sensor in the main heating supply pipe, and / or main intelligent electric two-way flow ratio distributing stop valve and main return temperature sensor in the main return pipe, main acquisition controller, water filter before the main remote flowmeater, and real-time monitoring main flowmeter connected to the output of the main acquisition controller.

Description

Technical field: [0001] The present invention mainly relates to a household metering system for centralized heating, and particularly relates to a household heating metering system for buildings or high-rise buildings, or to the transformation of an existing heating system and a method for metering and charging the system. Background technique: [0002] The single-pipe plumbing heating system in the prior art generally adopts a top-down series arrangement. This kind of system is equipped with heating pipes on the top layer to provide heating to the heating load of the lower layer in the longitudinal direction, and the return water of this layer then downwards. The first floor is heated until the bottom floor returns to water. The advantage of this up-and-down downstream heating system is that the layout structure is relatively simple, but its heating imbalance is more prominent. The upper heating users using this system get more heat, while the lower users get less heat; in addit...
