No negative pressure hot water direct supply unit

Abstract

A non-negative pressure hot water direct supply unit belongs to the field of hot water direct supply equipment. Including the buffer tank (5) and the control cabinet (11), the municipal heating pipeline (1) is connected to the buffer tank (5), and the outlet of the buffer tank (5) is connected in parallel with the high zone user (29) and the low zone user (20) Three water supply pipelines connected at the same time, characterized in that: a return chamber (27) connected to the high area user (29) and the low area user (20) is provided, and a pressure control valve is installed on the return chamber (27) (25), the outlet of the pressure regulating valve (25) is connected with the three-way pipe (23), and the other two openings of the three-way pipe (23) are respectively connected in series with the first bypass pipe (19) and the second bypass pipe (30 ), the first bypass pipe (19) and the second bypass pipe (30) are respectively connected in parallel to the two booster pipelines. The unit has reliable performance, can uniformly collect hot water during pressure relief, and has good anti-blocking effect.

Description

technical field [0001] A non-negative pressure hot water direct supply unit belongs to the field of hot water direct supply equipment. Specifically relates to a non-negative pressure hot water direct supply unit capable of uniformly collecting hot water during pressure relief and having good anti-blocking effect. Background technique [0002] At present, with the increasing number of high-rise buildings, the heating problem of high-rise buildings is an urgent problem to be solved. In the existing non-negative pressure hot water direct supply unit, there are mainly the following shortcomings: 1. The safety valve or pressure relief valve installed on the pipeline and the tank cannot be collected uniformly when the pressure is released. , because the medium in the pipeline is hot water, when the pressure is released, the hot water is released irregularly. On the one hand, it is easy to cause inconvenience in production, and on the other hand, it is a great waste of resources. ...

AI Technical Summary

Problems solved by technology

In the existing non-negative pressure hot water direct supply unit, there are mainly the following shortcomings: 1. The safety valve or pressure relief valve installed on the pipeline and the tank cannot be collected uniformly when the pressure is released. , since the medium in the pipeline is hot water, when the pressure is released, the hot water is released irregularly. On the one hand, it is easy to cause inconvenience in production, and on the other hand, it is a great waste of resources.

2. The pipeline is easy to block

3. After the hot water has completed the heat exchange between the users in the high area and the users in the low area, the hot water is directly returned to the municipal heating source, which is also easy to cause blockage at the municipal heat source

4. The safety factor is low, and there are not enough safety devices in the pipeline, which can easily cause safety accidents
