Abstract
The utility model provides a dynamic resistance balance valve. The dynamic resistance balance valve comprises a valve body, a valve deck, an automatic valve plug, a manual valve plug, a spring, a spring tube, a pressure sensing film, a pressure guiding channel, a change-over valve, a flow display plate, a pressure guiding connector, a locking switch, a locking screw, a locking sleeve and other components. The valve body is divided by the pressure sensing film into an upper pressure chamber and a lower pressure chamber, namely an above-film chamber and a below-film chamber. The flow display plate is inlaid in a valve rod of the manual valve plug and displays the flow of a certain opening degree of the manual valve plug. Downstream pressure is guided into the below-film chamber of the pressure sensing film through the pressure guiding channel. The change-over valve which controls the connection / disconnection of the pressure guiding channel is mounted on the spring tube and adjusted to realize switch between a flow control valve and a differential pressure valve. The locking switch and the locking screw are used for tightly abutting against the locking sleeve so as to realize the switch between the flow control valve and a manual balance valve. Due to the characteristics, the dynamic resistance balance valve has the function of a self-operated flow control valve, the function of the manual balance valve and the function of a self-operated differential pressure valve. The dynamic resistance balance valve is simple in structure, convenient to adjust, and suitable for both a system with constant flow and a system with variable flow, and has multiple functions.

Technical field
The utility model relates to control valve, and dynamic resistance balance valve belongs to International Classification of Patents F16K17/20 excess-flow valve technical field.
Background technique
In prior art, flow control valve is used for pipe network system, can only be used for the pipe network constant flow water system.In central air-conditioner and heating system, along with the application of the various power-saving technologies such as converter technique, temperature control technology and the enforcement of household-based heat metering, make the operating mode of pipe network system produce very large difference.The difference of operating mode is very different to selecting also of pipe network water equilibrium of forces product, as selects mistake just can not reach due effect.The uncertainty of operating mode makes selecting of hydraulic equilibrium product produce the uncertain technological innovation that this has just impelled the equilibrium valve manufacturer that the hydraulic equilibrium product is carried out from performance and function.The hydraulic equilibrium product is had multi-functional, and high-performance, to adapt to the demand of pipe network energy-saving run.
Dynamic resistance balance valve has self-operated flow control valve function, Differential Pressure Controller function, manual equilibrium valve function, can convert difference in functionality to according to operating mode, avoid system to change valve because of the change of operating mode, also solved simultaneously buying side's mistake and selected and make heating system can't bring into play proper efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that existing flow control valve can not be suitable for variable flow system, provide simple and practical, can be suitable for constant flow water system and can be suitable for again the rotation speed change total supply that heating management unit regulates the heat-source Cycles water pump according to outdoor climate and realize energy-conservation heat supply network, also applicable household-based heat metering is according to user's the heat supply network with heat request variable-flow energy-saving run.Can convert difference in functionality to according to the operating mode of heat supply network.
The purpose of this utility model is achieved through the following technical solutions.
Dynamic resistance balance valve, it comprises valve body, valve gap, and in valve body, its top is provided with manual spool, and is relative with manual spool, and the center in valve body middle part and bottom runs through that an automatic spool being set, and automatically is equipped with spring in the middle of spool; Be provided with pressure sensitive film in valve body, pressure sensitive film is divided into up and down two pressure chambers, i.e. epistege and hypostegal cavity to valve body.Spring is withstood in the pressure sensitive film upper end, and the lower end is pressed on automatic spool; The hypostegal cavity of pressure sensitive film is communicated with a pilot passage, and the pilot passage the other end communicates with the fluid passage of equilibrium valve, and downstream pressure imports the hypostegal cavity of pressure sensitive film by the pilot passage.
The utility model dynamic resistance balance valve is owing to having adopted above innovative design to have the characteristics such as simple in structure, easy to adjust, practical.
Description of drawings
Fig. 1 is the structure sectional view of the utility model dynamic resistance balance valve
In figure: 1 valve body, 2 valve gaps, 3 display panels, 4 manual spools, 5 automatic spools, 6 spring struts, 7 springs, 8 automatic spool peep holes, 9 pressure guiding joints, 10 switching valves, 11 pressure sensitive films, 12 pilot passages, 13 puzzle locked caps, 14 locking switches, 15 lock screw, 16 pollutant exhaust hole plugs, 17 locking covers.
Embodiment
Dynamic resistance balance valve, it comprises valve body 1, valve gap 2, is equipped with puzzle locked cap 13 at valve gap 2 tops.In valve body 1, its top is provided with manual spool 4, and manually spool 4 tops pass outside valve gap 2, and the above fixes a display panel 3.Display panel 3 is enclosed in puzzle locked cap 13.Display panel 3 shows the flow of manual spool 4 certain aperture.Relative with manual spool 4, the center in valve body 1 middle part and bottom runs through that an automatic spool 5 being set.Automatically be equipped with spring 7 in the middle of spool 5.Be provided with pressure sensitive film 11 in valve body 1, pressure sensitive film 11 is divided into up and down two pressure chambers, i.e. epistege and hypostegal cavity to valve body 1.Spring 7 is withstood in pressure sensitive film 11 upper ends, and the lower end is pressed on automatic spool 5.The hypostegal cavity of pressure sensitive film 11 is communicated with a pilot passage 12, and pilot passage 12 the other ends communicate with the fluid passage of equilibrium valve, and downstream pressure imports the hypostegal cavity of pressure sensitive film 11 by pilot passage 12.A spring strut 6 is installed in valve body 1 bottom, and the changing valve 10 that can control pilot passage 12 break-makes is equipped with in spring strut 6 outsides, realizes the conversion of flow control valve and pressure difference valve.The locking cover 17 of the automatic spool 5 of locking is housed in spring strut 6, and locking cover 17 is equipped with locking switch 14, and locking switch 14 is provided with lock screw 15.Hold out against by locking switch 14, lock screw 15, realize flow control valve and the manually conversion of equilibrium valve.The action that locks automatic spool realizes the resistance balance of pipe network.The opposite side that is positioned at locking switch 14 on spring strut 6 has a pressure guiding joint 9.Automatically on spool 5 axle center, bottom, an automatic spool access opening 8 is being arranged.Spring strut 6 bottoms are equipped with pollutant exhaust hole plug 16.
During adjusting, open puzzle locked cap 13, each customer flow is by the manual spool 4 of constant flow control, be adjusted to required flow valuve to display panel 3.After each user regulates and completes.The pressure sensitive film 11 of dynamic resistance balance valve will sensed pressure be stabilized in certain correct position to spool 5 automatically, and close changing valve 10 this moment, tightens lock screw 15 on locking switch 14 and makes locking cover 17 produce displacement to equal a spool 5 lockings automatically.Make each user reach resistance balance by actual demand, do variable-flow when system and regulate when flow is tuned up or turns down, each user will scale up or reduce flow, thereby the system that reaches changes according to outdoor climate the purpose that variable-flow is regulated.
