Abstract
The utility model discloses a dynamic equilibrium electric two-way valve comprising a valve body 1, a valve cover 12, a valve core 10, a valve rod 11, a valve upstream 7 and a valve downstream 8. A water flow cylinder 2 is arranged between the valve upstream 7 and the valve downstream 8 which are arranged on two sides of the valve body, and the water flow cylinder 12 is internally provided with a flexible path 6, a fixed path 9 and a piston spring 3; the bottom end of the piston spring 3 is connected with an equalizing piston 4; and the other end of the water flow cylinder 2 is provided with a water flow cylinder cover 5. The utility model can keep water flow unchanged when the pressure difference between the valve upstream and the valve downstream is changed, ensure higher comfort level and lower energy consumption and reduce the water flow noise and vibration, is more convenient to clean and change the valve core and has longer service life and smaller volume.
Description
Technical field
The utility model relates to a kind of heating ventilation air-conditioning system, is used for fan coil unit temperature control, also can be used in the system that other similar functions such as Region control requires.Be particularly related to a kind of dynamic balancing electric two-way valve.
Background technique
The water flow fluctuation of conveying was big, the temperature departure is big, the sometimes hot and sometimes cold shortcoming in room because thereby pressure surge makes greatly when traditional electric two-way valve was in the operation at part load state in system.
Summary of the invention
At above shortcoming, the utility model provides a kind of novel dynamic balancing electric two-way valve.
To achieve these goals, the technical field taked of the utility model is:
A kind of dynamic balancing electric two-way valve, comprise valve body 1, valve gap 12, spool 10, valve rod 11, valve downstream 7 and valve downstream 8, be arranged between the valve downstream 7 of valve body 1 both sides and the valve downstream 8 and be provided with flow tube 2, be respectively arranged with variable latus rectum 6 and fixing latus rectum 9 on described flow tube 2 barrels, described flow tube 2 inside are provided with piston spring 3, described piston spring 3 balance support pistons 4, the other end of described flow tube 2 is provided with flow cover 5;
Described valve body 1 material is a brass;
Described balance valve core 2 materials are the high tenacity compound;
Described spool 10 materials are brass;
Described valve rod 11 materials are stainless steel.
The beneficial effects of the utility model: in the time of guaranteeing that pressure reduction changes before and after the valve, flow remains constant, has guaranteed comfort level that the room is higher and lower energy consumption, can reduce the noise and the vibration of current, cleaning and replacing spool are convenient, and the life-span is longer, and volume is littler.

Embodiment
See also its implementation process of description of drawings:
A kind of dynamic balancing electric two-way valve has comprised the valve body 1 and the valve gap 12 of fixation, plays the spool 10 of regulating action, plays the valve rod 11 of interconnect function, valve downstream 7 and valve downstream 8, and valve downstream 7 and valve downstream 8 be medium import and media outlets respectively.The utility model before the valve of valve body 1 both sides 7 and valve after be provided with flow tube 2 between 8.Flow tube 2 is for there being the hollow cylinder of special construction, be respectively arranged with variable latus rectum 6 and fixing latus rectum 9 on the inwall, variable latus rectum 6 and fixedly latus rectum 9 all can make the MEDIA FLOW mistake, the inner chamber of flow tube 2 is provided with piston spring 3, the balance support piston 4 of described piston spring 3.When the pressure reduction of valve downstream 7 and valve downstream 8 changed, its differential pressure action made its pressure spring 3 on piston 4, and piston 4 slides up and down in flow tube inboard, thereby comes control flow rate by the openings of sizes that changes variable latus rectum.The other end of described flow tube 2 is provided with flow cover 5, and flow cover 5 plays sealing and fixed flow graduated cylinder 2.
When following several situation appears in valve upstream and downstream pressure reduction, in the flow tube different working staties can appear:
When valve downstream pressure P1 less than valve downstream pressure P2, and pressure reduction is during less than minimum operationg pressure differential, piston does not have pressure spring, current flow through through fixing latus rectum and variable latus rectum largest portion partly, flow at this moment raises along with the increase of pressure reduction.
When valve downstream pressure P1 greater than valve downstream pressure P2, and pressure reduction is during greater than minimum operationg pressure differential, piston begins pressure spring, and the current process fixedly part of latus rectum raises along with the increase of pressure reduction, and the flow of variable latus rectum part reduces gradually because piston turns down latus rectum.Therefore two flows summation of adding phase always remains unchanged.
When valve downstream pressure P1 greater than valve downstream pressure P2, and pressure reduction is during greater than maximum operating pressure differential, the complete pressure spring of piston, the flow of variable latus rectum part is zero, current are only by fixing latus rectum part.Therefore, flow increases with the increase of pressure reduction.
Described valve body 1 material is a brass, and She Ji benefit is like this, can make the life-span of valve body 1 longer, and volume is littler, and anti-corrosion.
Described balance valve core 2 and piston 4 materials are novel high tenacity compound, adopt the benefit of novel high-ductility polymer to be, the high-ductility polymer is fit to air-conditioning and cold and hot water supply system, and suitable work water temperature range is wide, not influenced by current frictional force, and less scaling.
The beneficial effects of the utility model: can guarantee that flow remains constant when valve upstream and downstream pressure reduction changes, guaranteed comfort level that the room is higher and lower energy consumption, can reduce the noise and the vibration of current, cleaned and to change spool convenient, life-span is longer, and volume is littler.The utility model is the temperature control that is used for the heating ventilation air-conditioning system fan coil unit, integration product with transient equiliblium and electronic two logical functions, can remain stable by assurance system flow when operating conditions changes, be used for the closed circulation system that heats, supply water or freeze, guarantee that each terminal flow conforms to design discharge.The water flow fluctuation of conveying is big, the temperature departure is big, the sometimes hot and sometimes cold shortcoming in room because thereby pressure surge makes greatly when having avoided being in the operation at part load state as traditional electric two-way valve in system.
Those skilled in the art's simple replacement and replacing all are within the protection domain of this patent.
