Turning back now to the exemplary setting of accompanying drawing, Fig. 3 to 5 illustrates fluid conditioner 100, and it includes the example lever assembly 102 with antivibrator 104 according to this utility model enlightenment.Except lever assembly 102 and antivibrator 104, fluid conditioner 100 is generally similar with the actuator 10 of Fig. 1.Therefore, identical accompanying drawing labelling is used to refer to the identical of fluid conditioner or substantially similar feature, and unless it is desired in order to, beyond understanding relative to lever assembly 102 and antivibrator 104, otherwise not repeat such explanation with reference to the explanation before it.Iting should be understood that lever assembly 102 and antivibrator 104 can be used for the fluid conditioner of number of different types and pattern, and enlightenment of the present utility model is not limited to example fluid regulator 100 definite shown in accompanying drawing, it is only for explanation purposes.
Lever assembly 102 includes lever 106 and antivibrator 104.Lever 106 includes pivot part 108, and described pivot part can be pivotally coupled to governor body 12 to pivot around the axis A horizontal-extending transverse to fluid passage 18 and/or to rotate.In this example, pivot part 108 includes pin 110, and lever 106 can be pivotally connected to governor body 12 by described pin, but other pivot linkage it is also possible that.The front end 112 of lever 106 is attached to flow control component 20, and the rear end 114 of lever 106 is attached to actuating rod handle 28.The vertical motion (it is caused in response to the vertical motion exporting 16 fluid pressure changes by barrier film 26) activating rod handle 28 makes lever 106 rotate around axis A, its then make flow control component 20 along fluid passage 18 longitudinal axis direction backward and/or forward horizontal shift, thereby make flow control component 20 shift between the open position spaced apart with valve seat 22 and the make position (as shown in Figure 3) that valve seat 22 can be engaged.
Antivibrator 104 is directly or indirectly such as attached to governor body 12 via the platform 116 between governor body 12 and antivibrator 104.In either case, antivibrator 104 is fixed on select location relative to governor body 12.Antivibrator 104 includes the spring member 122,124 that can rebound of one or more engagement, levers 106.Preferably, the spring member 122,124 that can rebound along with the direction of axis A parallel with a certain amount of power frictionally and slidably extrusion lever 106, described a certain amount of power is enough to reduce or even eliminates lever 106 around the less desirable of described axis A and/or uncontrolled pivot and/or vibration, and via activating, rod handle 28 is desired to be controlled motion and pivot amount necessary to the desired outlet pressure of maintenance in response to actuator 24 to allow lever 106.Thus, antivibrator 104 has cushioned lever 106 efficiently and has such as been quivered caused less desirable pivoting action by uncontrolled vibration, loose assembling and/or valve, and this can thus increasing useful life cycle and/or the accuracy of whole fluid conditioner 100.
The best is as shown in Figures 4 and 5, antivibrator 104 is the form of intermediate plate spring, described intermediate plate spring has matrix 120, can rebound left fork 122 and the right fork 124 that can rebound, the described left fork that can rebound and the right fork that can rebound form the spring member that can rebound.The left fork 122 that can rebound upwardly extends from the left hand edge of matrix 120, and the right fork 124 that can rebound upwardly extends from the right hand edge of matrix 120.The left fork 122 that can rebound and the right fork 124 that can rebound are spaced apart to form gap 126 between which.Gap 126 is preferably slightly smaller than the corresponding width W of the lever 106 part in gap.Thus, gap 126 receives a part for lever 106 so that the left fork 122 that can rebound and the right fork 124 that can rebound such as can be pressed from both sides to lever 106 by pressing from both sides the two opposite sides portion by lever 106 with rebounding.The size in gap 126 may be selected to be to apply the clamping of preliminary election, slip and/or frictional force against lever 106, does not stop lever 106 in response to the desired motion of control campaign activating rod handle 28 to reduce the less desirable vibration of lever and motion.Each of the left fork 122 that can rebound and the right fork 124 that can rebound slopes inwardly from matrix 120 upwardly toward the clamping zone 128 limiting gap 126.At clamping zone 128 place, the fork 122,124 that can rebound such as is flared out with a bending section or an angle then towards their far-end 129, thereby forming the acceptance division 130 of constriction, lever 106 can be such as directed in gap 126 by described acceptance division during assembling fluid conditioner 100.In the present arrangement, matrix 120, the left fork 122 that can rebound and the right fork 124 that can rebound all are formed by single material (such as steel) band that can rebound, and described band has such as been shaped to the shape in accompanying drawing by known bending techniques；But, intermediate plate spring can pass through to be enough to provide any method against chucking power desired by lever 106 to be formed.Additionally, each structure of intermediate plate spring can have other shape, vibrate so that cushioning lever 106 is less desirable as long as the left fork that can rebound 122 and the right fork 124 that can rebound can clamp to lever 106.And, antivibrator 104 is not necessarily limited by the form with intermediate plate spring, but other form with one or more spring members that can rebound can be adopted, the described spring member that can rebound is similarly adapted to frictionally and/or ground engagement, levers 106 of rebounding pivots vibration so that cushioning lever 106 is less desirable.
Lever 106 includes the lever arm 132 extending to rear end 114 from front end 112.Lever has left side 134 and right side 136, described left side and right side, and from top 138 to bottom margin 140 and 114 ground extend to the back-end from front end 112.Preferably, left side 134 and right side 136 are parallel to each other so that lever 106 has the constant width W running through whole lever 106.Preferably, lever 106 is formed by the material of one piece of general horizontal (smooth).By this way, lever 106 such as can relatively easily be cut by metal bar material one piece smooth and form；But, lever 106 can adopt other shape and not need have shape smooth, level.First connection part 142 installs front end 112 place in lever arm 136, and the second connection part 144 installs rear end 114 place in lever arm 136.First connection part 142 is the form of groove, and described groove extends through left side 134 and right side 136 and downwardly extends from top 138 adjacent front end 112 ground of lever arm 132.Described groove is sized to and receives the projecting block 146 coupled with flow control component 20, so that this projecting block 146 can slide in described groove and/or rotate when lever 106 pivots around axis A.Second connection part 144 is the hook-type of the rear end 114 of lever arm 132 or downward angularly part, and this part is assemblied on the saddle part 44 activating rod handle 28.But, the first connection part 142 and the second connection part 144 can take other form according to the needs coupled with flow control component and actuator.
Lever 106 also includes the lug 150 extending in the gap 126 of antivibrator 104.In the present arrangement, lug 150 is formed one protruding, and described projection downwardly extends from the bottom margin 140 of lever arm 132 and installing at interval at pivot part 108 and the second connection part 144.But, lug 150 can adopt other shape in the gap 126 between the spring member that can rebound being arranged to be sandwiched in antivibrator 104 and/or form.As the best is shown in figure 3, lug 150 has following height, and this height is sized to be kept between the fork 122 and 124 being clipped in intermediate plate spring with running through the whole range of movement of lever 106 between the open position and make position of flow control component 20.Thus, lug 150 allows antivibrator 104 to engage with lever 106 sometimes keeping, and thereby makes antivibrator 104 can run through the motion of lever 106 whole range of movement ground cushioning lever 106.Preferably, lug 150 has parallel left side and right side, described left side and right side and is coupled so that antivibrator 104 keeps constant while the chucking power of lever 106 runs through lever 106 range of movement by left fork 122 and the right fork 124 that can rebound can rebounded accordingly.But, the surface of lug 150 can be shaped differently (such as the nonparallel sidepiece by sidepiece that is that have constriction or that bend) so that the chucking power of antivibrator 104 changes relative to the diverse location along lever 106 range of movement.In some settings, lever arm 132 can not be formed by one piece of planarization material as mentioned above with constant width W, in this case, lug 150 can be the only part that the whole range of movement running through lever 106 of lever 106 is installed between fork 122 and 124 in space 126.By this way, difform lever energy is modified to include lug 150, to engage antivibrator 104 and to provide constant extruding and/or chucking power not to change basic configuration and/or the structure of lever remainder with cushioning lever.In addition, although lug 150 is shown as on the bottom margin 140 of lever arm 132, in other is arranged, lug 150 can installed between top 138 and bottom margin 140 along other position of lever 106 (such as along top 138), and/or depends on that the antivibrator 104 position in governor body 12 and/or desired mechanical lever advantage are installed in front end 112 or rear end 114 place.
Pivot part 108 includes pin 110, and described pin extends through aperture 152, described aperture through lever arm 132 along the bottom margin 140 Offset portion 154 near front end 112.In particular, Offset portion 154 offsets downward from lever arm 132 so that aperture 152 offsets thus the vertical motion of rear end 114 is converted into the horizontal movement of front end 112 downwards and backward from the first connection part 142.Pin 110 preferably has frictional fit closely or otherwise such as coordinates regularly in aperture 152 by welding or other fixing connection measure, in order to stop lever arm 132 to move individually relative to pin 110 with rotary motion or lateral movement.In some settings, pin 110 can such as form with lever arm 132 by casting or machine, and in this case, aperture 152 can be removed owing to there is no need.But, pivot part 108 is not necessarily limited by concrete setting, and it can be deployed in other set-up mode lever 106 and governor body 12 be able to being pivotally connected.In current example, Offset portion 154 is spaced apart with lug 150, and lug 150 is spaced apart with the second connection part 144, so that lug 150 is installed between pivot part 108 with rear end 114 and spaced apart with pivot part and rear end.But, the exact shape of top 138 and bottom margin 140 and profile can be revised to coordinate flow control component 20, governor body 12 as required and activate the concrete setting of rod handle 28, if antivibrator 104 can as previously noted can slidably and a part for clamping engagement, levers 106 to cushion less desirable vibration.
Antivibrator 104 can pass through any applicable mechanism and couple regularly with governor body 12.In the example in the drawings, form is that the antivibrator 104 of intermediate plate spring is attached to platform 116 by one or more securing members 156 (such as screw or rivet).But, antivibrator 104 can utilize other mechanism to be attached to governor body, such as by welding, bonding or be formed as the integrated component of governor body 12 and couple.
The lever assembly such as including lever 106 and antivibrator 104 described herein can help to extend the useful life of fluid conditioner 100 and/or improve its accuracy.Additionally, the lever with lug 150 can allow the lever of difformity and size to be easily adaptable antivibrator 104 without the shape generally re-constructing lever.Additional technique effect and/or benefit realize also by the lever assembly with antivibrator as disclosed herein.
