The adjustable flow resistance reduces the number of unique items to provide a selection of valve assemblies with different flow resistance. The rotational flow control member (8) provides low torque flow control allowing the use of low torque servo motors (10) yet which can provide highly accurate proportional flow control.
Description
The present invention relates to the sub-component of valve, particularly be adapted at controlling in the valve assembly sub-component of the valve of the flow between first fluid pipeline and the bypass fluid pipeline.
A kind of known applications of this valve assembly is to be used for fan coil unit heating or cooling system.Fluid that heat in fan coil unit heating or cooling system or cooling flows through coil pipe, and this coil pipe of blows air over, this fluid are normally supplied with under fixed pressure and the temperature substantially at one.How much controlling of the temperature of coil pipe and the temperature of the air fluid flow by selecting to flow through coil pipe and/or bypass duct.
Known valve with a kind of so optionally bypass functionality has first, second and three-fluid supplier, (be connected to reflow pipe from first fluid supplier (being connected to the return terminal of coil pipe) to the three-fluid supplier, this reflow pipe makes reflux fluid turn back to fluid supply place) fluid flow and fluid flow from second fluid supply apparatus (be connected to an inflow catheter, this flow ipe makes fluid supply place be connected with coil pipe) to the three-fluid supplier control simultaneously by single, linearly moving flow control component.Fluid supply apparatus can constitute by single passage, pipeline or an analog or by two or more functional component in parallel (acting), and a given fluid source and the destination of fluid are linked up.
In one embodiment, the three-fluid supplier be from have annular valve opening on one and once the central lumen of annular valve opening supply with.Having up and down, the flow control component of the seal element of width gradual change can move in chamber by a linear actuators.Last annular valve opening from this chamber to the first fluid supplier, following annular valve opening from the chamber to second fluid supply apparatus.Like this, a valve assembly can constitute an assembly with four holes (port) easily, two holes in four holes of first fluid supplier and three-fluid supplier and this communicate, a flow ipe is connected with two other outlet, and second fluid supply apparatus and this flow ipe certain between latter two hole a bit connect.
When valve member was pulled to its extreme lower position, last annular valve opening was opened fully and is descended the annular valve opening to close fully.When valve member during in the extreme higher position, last annular valve opening close fully and down the annular valve opening open fully, and when valve member during in the neutral position, last annular valve opening and following annular valve opening are all opened, the degree of opening is variable.Instantly the annular valve opening finishes when closing entirely, bypass duct is closed, coil pipe receives the whole flows from fluid supply place like this, when last annular valve opening is closed fully, the coil pipe pipeline becomes bypass duct fully, when in position intermediate, can access variable, a selectable flow by coil pipe.
The cheapest method of controlling this valve is to utilize a wax-wrapped pill that bypass duct is changed between the state of standard-sized sheet and full cut-off, and when wax-wrapped pill was energized, it acted on a Returnning spring.Yet this provides a kind of rough control function and often unreliable in connecting sort run.
A kind of more complicated but more expensive method is to act on Returnning spring and the state of wax-wrapped pill is controlled by the heating element that the pulse signal with a width modulated is applied to an inside with wax-wrapped pill, and the position of the degree of the dissolving decision valve of wax-wrapped pill is between 0% to 100%.
Another method is to use by an electric motor driven electronics location linear actuators, and this electronic function is controlled to the position of selected needed valve stroke.This provides more accurate proportional control than wax-wrapped pill actuator, has increased but cost is the expense of actuator.
Yet a common trait of these existing valve assemblys is that when activateding, they have a linear stroke, and when closing bypass duct, the valve element must be positioned at and withstand (SEATAGAINST) hydrodynamic pressure, needs the retention force of a 100N usually.The wax-wrapped pill actuator can also be with stroke (approximately the being 2 millimeters) operation of the linearity of a weak point.
As everyone knows, this valve assembly should be chosen as at bypass duct and close fully and coil pipe pipeline when opening fully, obtains a flow resistance of being wanted, and vice versa.This value of wanting depends on that coil pipe reaches the flow resistance of relevant fluid feed element.The measurement of flow resistance is a dimensionless parameters Kv, for a given pressure drop, and the higher bigger flow of Kv value representative.
Existing valve assembly has several shortcomings.The needs that a flow resistance characteristic and a specific coil pipe pipeline are complementary require to make the same valve assembly of several patterns, thereby have increased the demand of finished product.Linear stroke, especially during the short-term stroke, the profile that means the valve element must be processed very accurate, and the solid in the fluid is clamped in the little gap between valve and the valve seat easily.They also require to have the high-power output actuator of high cost.The response time of wax-wrapped pill actuator is very slow, and all required test loop of therefore this complete valve assembly are very consuming time and therefore cost height.
Similarly consider to be applied on the valve assembly in two holes, here, control is by the flow velocity of the valve assembly between inflow entrance and the outflow opening, and, under the ideal situation, when valve assembly is in the position of opening fully for the flow resistance of specific application choice minimum.
The sub-component that the purpose of this invention is to provide a kind of improved, multi-functional valve, the sub-component of this valve can be used in the valve assembly with two or three or four holes, and these valve assemblys exist these shortcomings of existing apparatus.
Therefore, the invention provides a kind of sub-component of valve, the sub-component of this valve comprises: have the flow resistance parts of a flow cell, first, the 3rd and third channel extend through the body of first valve member from this flow cell; A flow control component, these parts can be arranged in flow cell to be in sealing relationship with the flow resistance parts, and these parts have several valve elements to be used for optionally regulating the degree of opening of first and second passages; This flow control component and flow resistance parts can relatively rotate so that these valve elements can complete closed first passages and open second channel fully, partly open first and second passages, or open first passage fully and close second channel fully.
, pro rata, close or open second channel more when thereby flow control component and flow resistance parts relatively rotate when opening or closing first passage more.
The sub-component of valve of the present invention can be used on and obtains concrete application in the valve assembly, and this valve assembly comprises: the valve casing of a valve casing chamber is arranged, be extended with first and second fluid supply apparatus from this valve casing chamber; Sub-component according to valve of the present invention; And the flow resistance parts that stretch into this valve casing chamber, be sealed in the valve casing, and relatively being positioned at a position in two or more possible positions in the valve casing, each position provides first and second fluid supply apparatus and separately different desirable degree of overlapping of first and second passages.
The sub-component of valve can be used in the valve casing that two fluid supply apparatus are only arranged so that a valve to be provided, thereby this valve can be controlled flow from the first fluid supplier to second fluid supply apparatus when flow control component is in a fully open position, in the scope of available flow resistance, can regulate so that a flow resistance of being wanted to be provided.The sub-component of this valve also can be used in the valve casing that comprises the three-fluid supplier, the three-fluid supplier stretches out from the valve casing chamber, and be configured to a valve assembly that three holes or four holes are arranged, in this case, overlapping the by-pass flow amount and the full flow Kv of valve assembly simultaneously of first and second fluid supply apparatus and first and second passage, so the ratio of Kv value can automatically remain on a value of being wanted, as 10: 7 (the full flow value is than by-pass value).
Because a kind of structure of the sub-component of valve can be used in the valve assembly in two, three or four holes, so can reduce the finished product demand of the such scope of valve assembly, this will explain below.
Flow control component rotation is with by closing the flow of a given passages regulate fluid, and this can realize by a shear action.This shows that desired actuation force and hydrodynamic pressure or the hydrodynamic pressure that causes owing to flowing are irrelevant.Therefore, can provide a kind of valve assembly now, this valve assembly is the movement requirement energy still less that is implemented between the working state than the existing valve assembly that uses linear actuators.Therefore for example, valve assembly of the present invention can move under the moment of the such order of magnitude of 0.3Nm, and valve assembly of the present invention can drive with a servomotor that quite cheaply, obtains easily.For example, aircraft control surface actuator can use a model, this actuator has the servocontrol machine system of one, and the servocontrol machine system of one can provide the ratio turning effort of highi degree of accuracy (be accurate to 0.1 degree), and price is quite low and be complementary with existing controller software design.And, do not need controller hardware output high-power (non-CPU rank) actuating current, thereby avoid to high power component such as trigger triode are provided, relay, D-A transducer etc. and need the expense of cost.
The flow resistance parts can be formed at many positions and be installed in the valve casing chamber, and these many positions are by, for example keying element decision.Best, thus the flow resistance parts can the two or more positions in the valve casing chamber between rotation can be regulated flow resistance after the assembling fully at valve.
The flow resistance parts can keep by a Lock Part with respect to the rotational position of valve casing, and this Lock Part is removably mounted on the valve casing/also can meshes with valve casing, and can with the part engagement of flow resistance parts.For example, Lock Part can comprise groove and be engaged on that first parts in this groove can be nibbled and part.
Best, the chamber of valve casing is columniform, but also can be with other configuration, as taper shape.In this embodiment, flow control component can remain in the valve assembly by a pair of pin that is spaced apart from each other, and these pins are arranged in valve body and are engaged on the relative both sides of circular groove of the outer wall of flow control component.When being sandwiched between valve casing and static (captive) flow control component, the flow resistance parts also the flow resistance parts can be remained on corresponding position in the valve assembly.These pins can pass the pair of holes that is formed in the flow resistance parts respectively, and the size in these holes may be selected to allow the flow resistance parts to rotate to each position in two or more possible positions with respect to valve body limitedly.The size in these holes in the flow resistance parts make in second fluid supply apparatus hydrodynamic pressure can with the flow resistance component axial shift to flow control component.
This valve assembly can comprise the mounting points that is used to install servomotor.
This flow control component can comprise one or more elements, the arm that for example a plurality of Control Shafts that are basically perpendicular to flow control component stretch out, and these arms be allow the manual tune flow control component with respect to valve casing pivotal position and this arm can accurately be set to known position, the position of injuring out fully or closing fully for example, for example, be provided with the servo of valve or test.
