Abstract
The utility model discloses a flange type dynamic flow equalizing valve, wherein two valve bodies are connected each other through bolts, a valve bag fixed disk is arranged on the buttjunction portion of the two valve bodies, the fixed disk is provided with two valve bags, each valve bag is composed of a valve bag base, a valve bag cover and a valve bag cover spring, the valve bag cover is fastened on the valve bag base, the valve bag cover spring is arranged between the valve bag base and the valve bag cover, the valve bag cover is also provided with a flux hole, and one end of the valve bag base is provided with a through hole. Compared with traditional electric regulating valves, the equalizing valve of the utility model is not at all dependent on external forces (e.g. manpower, electric power), has a low requirement to the working environment, and saves energy well in a design effort pressure differential range.
Description
Technical field
The utility model relates to a kind of valve, exactly is a kind of flange-type dynamic flow balance valve.
Background technique
The newly-built building of northern China adopts the dwelling house of central heating must have the control of branch family, household metering function, so just requires the regulation and control (regulation and control of flow) of temperature between each floor not disturb mutually each other.Small-bore fluid pilot line such as central air-conditioning system heating or refrigeration also require each room to have temperature independent regulation function in addition.This all requires the fluid transmission ﹠ distribution of system to have the transient equiliblium function.The method that traditional reversed return type designs or pipeline is installed the quiescent flow equilibrium valve endways can't solve this load difference, working condition belongs to the dynamic water conservancy imbalance of regulating variation at random.
Summary of the invention
The utility model is at fluid pilot line bore features of smaller such as the indoor control system of central heating, central air-conditioner, design and develop a kind of small-bore, full-automatic equilibrium valve of small flow that satisfies the rill requirement, solve the dynamic imbalance in fluid control fields such as urban heat supplying, central air-conditioner.
For reaching above purpose, the utility model two valve bodies link together by bolt, joint at two valve bodies is provided with a valve courage fixed tray, on valve courage fixed tray, be provided with two valve courages, the valve courage is made of valve courage base, valve courage lid and valve courage lid spring, and valve courage lid is fastened in the valve courage base, is provided with valve courage lid spring between valve courage base and valve courage lid, cover at the valve courage and also to be provided with metering orifice, be provided with the water port at an end of valve courage base.
Its control principle is the size that the inner self-powering type control unit of installing (cylindrical compression spring or pneumatic spring) can be regulated and control area of passage according to the change self-powering type of pressure reduction before and after the valve; keep constant when making output flow in the pressure reduction operating range of design; do not compressed fully in the maximum operating pressure differential valve flow hole that is higher than design, valve has the overcurrent self-protecting function.
By above setting, the utility model is compared with traditional electric control valve, and in the design work pressure differential range, this equilibrium valve does not rely on external force such as manpower, electric power fully, and working environment is required to reduce, and is also more energy-conservation.
