Constant-pressure current stabilization interrupter and high-rise heating system

Abstract

The invention relates to a constant-pressure current stabilization interrupter and a high-rise heating system. The constant-pressure current stabilization interrupter comprises a shell and a support. A water inflow pipe, a water outflow pipe, a high-region water return drive pipe and a water supply drive pipe are arranged on the shell. The upper portion and the lower portion of the shell are provided with a valve plug control mechanism and a flow control mechanism respectively. The high-rise heating system comprises a low-region hot water supply pipe, a booster pump, a high-region hot water supply pipe, a high-region radiator, a high-region water return pipe, a low-region radiator, a low-region water return pipe and a constant-pressure current stabilization interrupter body. The water inflow pipe is communicated with the high-region water return pipe, the water outflow pipe is communicated with the low-region water return pipe, the high-region water return drive pipe is communicated with a branch of the high-region water return pipe, and the water supply drive pipe is communicated with a water outflow pipe branch of the booster pump. The water current pressure and flow are controlled and regulated through the constant-pressure current stabilization interrupter body, constant current, constant pressure and instantaneous stop of water current are achieved, the dynamic pressure of the water current in the heating system is reduced, the static pressure is isolated in time when the system is stopped, and the heating system more safely runs.

Description

technical field [0001] The invention relates to a constant-voltage and steady-flow blocker and a high-rise heating system using the constant-voltage and steady-flow blocker. Background technique [0002] The most economical way to heat a high-rise building is to use the original low-zone heat source system to directly connect the heating system to realize a system that supplies heat to the high-zone radiator and the low-zone radiator at the same time. This system must reduce the pressure of the heating return water in the high zone to To prevent the backwater in the high area from breaking down the radiator in the low area, the existing high-level heating system includes a booster pump, a control system, a pressure reducing valve, a radiator in the high area and a radiator in the low area, etc. The booster pump and the control system are used for The heating medium enters the radiator in the high area, and the pressure reducing valve is mainly to reduce the dynamic pressure ...

[0002] The most economical way to heat a high-rise building is to use the original low-zone heat source system to directly connect the heating system to realize a system that supplies heat to the high-zone radiator and the low-zone radiator at the same time. This system must reduce the pressure of the heating return water in the high zone to To prevent the backwater in the high area from breaking down the radiator in the low area, the existing high-level heating system includes a booster pump, a control system, a pressure reducing valve, a radiator in the high area and a radiator in the low area, etc. The booster pump and the control system are used for The heating medium enters the radiator in the high area, and the pressure reducing valve is mainly to reduce the dynamic pressure of the return water in the high area. Under the increasingly urgent situation of energy saving, the heating system needs to be adjusted frequently, the flow of the heating system is changing, and the pressure It will also change accordingly. For example, when the system flow decreases, the pressure reducing valve cannot reduce the flow area accordingly, and the outlet pressure of the pipeline will inevitably increase, resulting in overpressure of the system in the low area and causing damage to the entire system.

When the system stops due to power failure or other circumstances, the booster pump stops working, and the dynamic pressure disappears. The return water of the radiator in the high area forms a higher static pressure than the radiator in the low area, and the pressure reducing valve cannot be closed in time. zone system is isolated from the low zone system causing this static pressure to be a threat to the safety of the low zone radiator
