Description
Technical field
The present invention relates to the valve technology field in heating system, say it is a kind of simple in construction, with low cost in detail, according to
The liquid-inlet of setting or the pressure of outlet automatically adjust the voltage stabilizing variable rate valve of valve body flow.
Background technology
It is known that in the heating system of skyscraper, in order to ensure being no more than with water, heating equipment for low area part
Its bearing capacity, often the booster apparatus system in low area He Gao areas be provided separately, under different pressurization points run, can just accomplish
High area and low area's part system are independent of each other, it is ensured that system safety.Thus considerably increase the investment of booster apparatus station and transport
Row expense.As high residential building is more and more, low area's heating system is with high area's heating system and in the presence of in a heating system；This
After the booster of Yang Danggao areas heating system has a power failure, traditional regulating valve is unable to the heating water that automatic-sealed lives high sound zone system, makes
The heating water of high sound zone system flows to low sound zone system in water pump power failure moment by return pipe, can so cause low sound zone system superpressure,
Low area's heating facility superpressure is caused to burst, influence safety can cause people's property, life security when serious.
In the heating system of low-rise building, in order to ensure that the heating equipment of low area part is no more than its bearing capacity, together
When ensure heating system pipe network poised state, traditional method is exactly self-operated type pressure difference, flow balance valve on feed pipe.Rely on oneself
Formula pressure difference, flow balance valve are not only complicated, cost is high, and because its automatic sensing structure interval is small, easily blocks very much and lose
Spirit, has a strong impact on heating quality, and operational management personnel, for heat supply of meeting an urgent need, just remove in the case where that can not overhaul to it,
Heat supply network hydraulic regime after dismounting more deteriorates, in order to meet the heating quality of system end user, then often takes replacing big
The water pump operation of power, cause imbalance it is more serious, operating cost further increases, and heating system becomes " a hypertension
Patient ".
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art there is provided one kind is simple in construction, with low cost, according to setting
The pressure of fixed import or export automatically adjusts the voltage stabilizing variable rate valve of valve body flow.
