Embodiment
With it is known, flow control components are usually coupled to the fluid conditioner of actuator using pipeline compared with, here
Flow control components are coupled to actuator by the fluid conditioner of the example of description using valve rod.In some instances, the valve
Bar can include passage, so that the flow control components pressure equilibrium, it is therefore desirable to which less power is opened and/or closed
The flow control components.It is, therefore, possible to provide less actuator, thus reduces cost.In addition, compared to traditional seat
Circle, the fluid conditioner of the example described herein, which is used, to be provided by elastomeric material (for example, elastic sealing element, disk or ring) institute
The valve seat or seat ring of the bearing-surface of composition.Therefore, significantly decrease or avoid due to the impact flow in such as technique stream or
The abrasion to elastic sealing element that particulate is produced.
In some instances, sieve or filter can be coupled to the seat ring to filter or prevent the impurity in technique stream
(such as big particulate) flows downstream to the outlet of the fluid conditioner.Especially, the filter can be by multiple discontinuous
Curved surface is constituted.Therefore, when being used for the technique stream with relative low temperature, the filter can be not easily susceptible to the shadow of ice formation
Ring.
Further, it is different from traditional fluid conditioner, the actuator shell of the fluid conditioner of example described herein
Inner surface have bending or smooth profile or shape.So, the diaphragm of actuator can with the contact surface area of increase with
The inner surface contact of actuator shell, it reduce the stress concentration on the diaphragm in contact surface.Additionally or alternatively, by valve
The diaphragm plate that bar is coupled to the flow control components can be dimensionally smaller, to allow the diaphragm to be adjusted compared to conventional fluid
Device more freely bends or bent.Allowing the diaphragm freely to bend or bend the part significantly reduced on diaphragm should
Power.The stress raisers so reduced significantly increase cycle life or the fatigue life of the diaphragm, thereby reduce dimension
Shield and cost.
Below in conjunction with Figure 1A and 1B brief description is provided to known fluid conditioner 100.Figure 1A is that known fluid is adjusted
Viewgraph of cross-section saving device 100, splitting, in an open position 102 fluid conditioner 100 is shown in the figure left-hand side,
And show in the closed position 104 fluid conditioner 100 in right-hand side.Figure 1B is conventional fluid adjuster in Figure 1A
100, amplification partial cross-sectional view.
Reference picture 1A and Figure 1B, it is known that fluid conditioner 100 include being coupled to the actuator 106 of valve body 108.The actuating
Device 106 moves flow control member or throttle ele-ment 110 relative to seat ring 112, to control the passage 116 by the valve body 108
Flow of fluid.
The flow control components 110 of the fluid conditioner 100 are illustrated as disc valve.The flow control components 110 have
Seal disc 118, disk seat or retainer 120, disk locator 122 and stem adapter 124.The seal disc 118 is substantive dish type
Ring, and be made up of elastomeric material.But, when under severe use condition (for example, fluid has high speed relatively
And/or high temperature relatively) in use, the elastic packing disk 118 is readily able to abrasion, and can by quick corrosion and
Damage.For example, as shown in Figure 1B, the impact flow caused by relatively high speed fluid stream 126 causes relatively large power can be with
It is applied on seal disc 118, thus causes seal disc 118 to wear and tear.The abrasion caused on elastic packing disk 118 can be prevented
Flow control components 110 are normally sealed in seat ring 112, and to need to close or by-pass procedure system, close to change this
Closing disk 118.Therefore, the flow control components 110 need the maintenance increased.
In the example shown, the actuator 106 includes upper casing 128 and lower casing 130, and they contain the He of diaphragm plate 132
134.The diaphragm plate 132 and 134 in the exercisable coupling of pipeline 138 with fixing diaphragm 136.Therefore, the He of diaphragm plate 132
Pipeline 138 and flow control components 110, by pipeline connection 140, are coupled to diaphragm 136 by 134.But, as shown in Figure 1A
Pipeline connection 140 significantly increases manufacturing cost and complexity.For example, pipeline connection 140 requires multiple seals 142
Sealed between pipeline 138 and valve body 108 and/or housing 144.
Further, due to pipeline connection 140, travel indicator 146 is coupled to diaphragm plate 132 to provide the flowing control
The instruction of position of the component 110 relative to the seat ring 112 processed.The trip indicator 146 is coupled to diaphragm by snapping connection
The hole 148 of plate 132.It is such snap connection it is firm unlike being for example threadedly coupled, and may be susceptible in operation by from
(for example, being drawn out from diaphragm plate 132) is pulled open on diaphragm plate 132, increased maintenance and closing is thus needed, stroke is referred to
Show that device 146 reconnects to diaphragm plate 132.
Additionally or alternatively, load of the diaphragm plate 132 and 134 transmission from diaphragm 136, with open position 102
The movement pipeline 138 between closed position 104, and therefore diaphragm plate 132 and 134 be dimensioned to support it is relatively large
Transmission load.In operation, the pressure difference of cross-film piece 136 causes diaphragm 136 to bend or bend, and causes flow control components 110
Moved by pipeline 138 relative to seat ring 112, to control the flow of fluid by passage 116.But, diaphragm plate 132 and 134
And/or actuator shell 128 and 130 forms fulcrum 150 or with acute angle or rough contact surface 152.Therefore, diaphragm
136 are restricted to relatively small surface area is bent around or bending.Additionally or alternatively, the diaphragm 136 is with relative
Small contact surface engages the acute angle portion 150 and 152, and/or actuator 106 of diaphragm plate 132 and 134, thereby increases diaphragm
136 contact area stress concentration.This stress raisers for putting on diaphragm 136 can significantly decrease the diaphragm
136 cycle life or fatigue life, thus cause maintenance and the cost increased.
