Description of drawings
According to regarding to the explanation of plurality of embodiments down and with reference to accompanying drawing, further details of the present invention, advantage and characteristic will become obviously, in the accompanying drawings:
Fig. 1 has shown the diagram simplified cross-sectional view in half one of the valve of first operating position according to first embodiment of the invention,
Fig. 2 shown with Fig. 1 in valve corresponding, at second operating position and be the diagram of the valve of somewhat modified form,
Fig. 3 shown with Fig. 1 in valve corresponding, at the 3rd operating position and be the diagram of the valve of somewhat modified form equally,
Fig. 4 has shown the sectional view according to the valve of second embodiment of the invention, and
Fig. 5 has shown the valve according to third embodiment of the invention.
The specific embodiment
In Fig. 1 to Fig. 3, show valve 1 respectively in a simplified manner according to first embodiment of the invention, wherein according to diagram, only the first half is selected and illustrates in the drawings, and promptly half one of visible valve above the longitudinal axis L representes with valve 1 below.
Correspondingly, valve 1 has lining 2, and sliding part 3 is directed in lining 2.In this case, sliding part 3 on the direction of the longitudinal axis L that is parallel to lining 2 by means of back-moving spring 4 by prestressing, thereby and be pushed against opposite edges 6, it is inboard and be positioned at lining 2 places that these opposite edges 6 are arranged on lining 2.
For this reason, sliding part 3 has stop surface 5, and according to the angle [alpha] that Fig. 3 indicated, this stop surface 5 is arranged to tilt with respect to longitudinal axis L.Because the effect of back-moving spring 4, the stop surface 5 of sliding part 3 is with fluid sealing mode butt opposite edges 6.This means that the sealing contact between stop surface 5 and the opposite edges 6 produces the blocking action of valve 1.
The conventional flow direction of the hydraulic fluid H of valve actuating device 1 in valve 1 represented by arrow
.Preferably corresponding to the direction of opening of valve actuating device (door that is correspondingly connected), wherein valve 1 block flows flow direction
.This for example prevents in fact under any circumstance that the door that is connected from exceeding maximum open angle.If surpassed maximum angle, then valve actuating device will be destroyed or for example collide on the wall.
In Fig. 1 to Fig. 3, arrow H represents the flow direction of hydraulic fluid H, if door that is for example connected or valve actuating device are carried out closing movement, then hydraulic fluid H can be introduced into when passing hydraulic pressure connecting portion 7, correspondingly is introduced in the outer recess 14 of sliding part 3.Through hydraulic fluid H is introduced in the recess 14, hydraulic fluid H is pulled on the stop surface 5.
Under state shown in Figure 2, for example, wherein door is opened, and the flowing of hollow space that fluid passes between sliding part 3 and the lining 2 exists more slowly or not.This means that the common closer spring of valve actuating device can utilize its whole active force to start bolt down procedure, this initial acceleration for the needs door is favourable.
Because the motion away from valve 1 that is associated therewith of (for example constituting piston 24) actuating device of gradual motion and the valve actuating device of door, back-moving spring 4 moves the stop surface 5 of sliding part 3 on more and more near the direction of opposite edges 6.As especially in Fig. 3, see better, in the zone of opposite edges 6, the hollow space between sliding part 3 and the lining 2 is narrower.This narrows down and hinders flowing of fluid, and thereby causes the speed that door is slower.Closing velocity for example thereby when closing movement finishes is hindered, and this has caused that damping closes.
Significantly, valve 1 can be inserted into equally, because when door just had been opened, piston 24 pushed away opposite edges 6 with stop surface 5.In this case, open at door and realized when motion finishes that damping opens.
Especially as it be shown in fig. 2, valve 1 preferably has bolt portion 15, for example is the shape of soket head cap screw head.At the place, outside, bolt portion 15 preferably has male thread portion 15a at least on some parts, and bolt portion 15 is screwed among the negative thread part 10a that is arranged in attached 10 by this male thread portion 15a.In order not make hydraulic fluid pass this screw connection and to be penetrated into the outside, preferably, bolt portion 15 can have on the outside around groove 15b, and seal 16 (the for example shape of O type circle) is inserted into this around in the groove 15b.Therefore, seal 16 inserts between attached 10 and the bolt portion 15 with fluid sealing mode because advantageously seal be configured to be flexible and be compressed in groove 15b and attached 10 opposite inner face between.
Make bolt portion 15 rotations cause bolt portion 15 translational motion along longitudinal axis L in attached 10.
Through spline adapter, for example lining 2 preferably utilizes anti-rotation protection to be accommodated in the housing 13 of valve actuating device.For example, like what in Fig. 2, see, housing 13 has the protuberance 13b that is used for this purpose, and protuberance 13b is along longitudinal axis L extension and outstanding in the direction of lining 2.2 of linings have the groove-like guidance part that is track or guiding recess 2d shape.Guiding recess 2d thereby only can move along protuberance 13b, thus lining 2 only can move to translation in attached 10, and according to Fig. 2, this is translation on left and right directions.Another advantage of this linear guide of lining 2 is, fluid pressure line 9 and hydraulic pressure connecting portion 7 can only change their position against each other along straight line, the edge straight line parallel for example with longitudinal axis L, and this increases processing safety.
As shown in Figure 3, the linear guide of lining 2 also can be realized through attached 10., compare with Fig. 1 and 2, attached 10 is set to longlyer, and for example has guiding recess 10d for this reason, and lining 2 is directed so that can vertically move along longitudinal axis L by means of the guiding protuberance 2h that is constructed in guiding recess 10d.
Set the reception space that is used for back-moving spring 4 lining 2 with the part place away from bolt portion 15 sliding part 3.For this reason, on the inboard of lining 2 and on the outside of sliding part 3, both have recess 2a or 3a respectively, and recess 2a or 3a are set at around recess respectively.Thereby, the cylindrical hollow space that between lining 2 and sliding part 3, has produced hollow.As selection, recess 3a is removed, and recess 2a is through self producing this hollow space, or turns around.Back-moving spring 4 is inserted into this hollow space and props up the abutment surface 2b by lining 2 with its that end towards bolt portion 15.This for example means that back-moving spring 4 is set to helical spring.Abutment surface 2b preferably constructs by the wall that limits recess 2a of lining 2.Back-moving spring 4 utilizes it to prop up by spring fitting 17 that end of bolt portion 15 dorsad.In the example depicted in fig. 1, spring fitting 17 is constructed by means of the ring of circumferential hoop in groove 3b that inserts sliding part 3.Ring preferably has rectangular shape in cross section, so that for back-moving spring 4 good abutment surface is provided.Groove 3b prevents that the left and right directions among hoop Fig. 1 and Fig. 2 from moving.
As selection, spring fitting 17 is only supported on the direction of back-moving spring 4, and example is as it be shown in fig. 2, because back-moving spring 4 is by tensioning in advance, so it prevents that spring fitting 17 from moving on the direction of back-moving spring 4.In the example shown, spring fitting 17 is placed on the recess 3a, and back-moving spring 4 also is placed on the recess 3a, therefore makes spring fitting 17 not need extra reception space.
As selection, as shown in Figure 3, sliding part 3 has male screw portion 3f in the end of bolt portion 15 dorsad, is nut or annular spring fitting 17 with negative thread and is swirled to male screw portion 3f.Thereby, regulate pre-tensioning and thereby the homing action of regulating back-moving spring 4 be possible.Advantageously, the cross section of ring has non-circular outline, for example; Be outer-hexagonal shape shape; Feasible ring can for example rotate through open-end wrench, thereby on the direction of abutment surface 2b or away from abutment surface 2b translation, moves, and can regulate the pre-tensioning of back-moving spring 4 thus.
In order to reduce the leakage loss on the direction of back-moving spring 4 in maximum possible degree ground; Sliding part 3 preferably further has circumferential hoop around groove 3c; Seal 18 to be inserting circumferential hoop around groove 3c with seal 16 similar modes, thereby and is arranged between lining 2 and the sliding part 3 with fluid sealing mode.
And; Likewise in that side relative of fluid pressure line 9 with bolt portion 15; Lining 2 preferably have with groove 3c, the similar circumferential hoop of 15c around groove 2c; Therefore seal 19 inserts circumferential hoop around groove 2c with the mode that is similar to seal 16,18, is arranged between attached 10 and the lining 2 with fluid sealing mode.
For the housing 13 that keeps valve actuating device and the leakage loss between the valve 1 as far as possible low; Preferably on the both sides of hydraulic channel 12, all be provided with seal 20,21, seal 20,21 preferably is arranged between housing 13 and attached 10 with clamped mode.For this reason, preferably in position locate to have circumferential hoop for attached 10, be respectively recess 10b, 10c around groove.Yet, with groove 10b, relative position place that 10c is corresponding, housing 13 also can have recess or groove 13a, in this situation, recess or groove 13a be positioned at the inboard and around.
Preferably, in the zone in the right side of fluid pressure line 9 and/or left side, attached 10 has external diameter, and this external diameter forms recess 11 thus less than the internal diameter of housing 13 in the zone that is associated.Thereby, the cylindrical hollow space of hollow for example be formed on attached 10 and housing 13 between.Because this hollow space flows in order to make fluid, fluid pressure line 9 needn't be aimed at fluid pressure line 12.But fluid pressure line 9,12 can be about arranged offset each other.Thereby, can make valve 1 standardization, standardized valve 1 can be used for heteroid valve actuating device, and this helps to reduce manufacturing cost again.
In order bolt portion 15 can not only to be moved on the direction of valve actuating device and to promote lining 2 but also can move lining 2 in the opposite direction, bolt portion has means (catch device) in the side towards lining 2.
In the example depicted in fig. 1, means is constructed by means of the block part 15c of annular preferably, and it sets transversely outstanding and outstanding towards lining 2 in the direction of longitudinal axis L preferably for.Lining 2 preferably has the recess 2e that complementally constructs with block part 15c.This means that block part 15c we can say the breech lock through recess 2e.From certain consumption of power, block part 15c and recess 2e are configured to and can engage and/or be disengaged, thereby help dismounting and installation.
As selection, though do not illustrate among the figure, bolt portion 15 has the recess that is similar to recess 2e, and lining 2 has complementary with this recess basically protuberance.
As selection, as shown in Figure 2, block part 15c constructs by means of the protuberance that lies on the lining 2 with clamping mode once more.This means, pull lining 2 by means of bolt portion 15 and realize through clamping or rubbing action.
As selection, as shown in Figure 3, block part 15c constructs by means of recess equally, makes between recess 2e and 15c, to form hollow space once more.The block part 23 that preferably has a shape of ring is inserted this advantageously in the hollow space of ring-type.
Because bolt portion 15 is with respect to lining 2 rotations, so annular shape is favourable.
To explain the task of bolt portion 15 now based on Fig. 2 and Fig. 3.If bolt portion 15 is under the condition shown in Figure 2, then the hydraulic fluid H from fluid pressure line 9 can almost flow in hydraulic pressure connecting portion 7 in the clear, because the almost alignment each other of fluid pressure line and hydraulic pressure connecting portion.Yet under condition shown in Figure 3, wherein bolt portion 15 further moves on the direction of fluid pressure line 9, before arriving hydraulic pressure connecting portion 7, initially must pass the narrower space 22 between attached 10 and the lining 2 from the hydraulic fluid H of fluid pressure line 9.Thereby flowing of fluid is obstructed significantly.As a result, back-moving spring 4 need apply less power is pressed against the stop surface 5 of sliding part 3 lining 2 with fluid sealing mode opposite edges 6.In addition, this motion of the feasible ability door leaf that damping connected that narrows.Obviously, space 22 can be configured to make flowing hardly of fluid or not interrupted.Therefore, wherein damping is provided and has blocked the valve 1 that action can be conditioned.The bolt portion 15 thereby come-at-able simple selection from the outside is provided allows valve 1 to be suitable for each valve actuating device.
As shown in Figure 3, housing 13 is modified slightly.As appreciable, housing 13 is substantially similar to the housing 13 of Fig. 1 and Fig. 2.Yet, to compare with these figure, fluid pressure line 12 is set skew to the right for.Importance along the recess 11 of the broad of longitudinal axis L becomes obvious this moment.Because this width; Valve 1 can use in the housing with heteroid fluid pressure line 12 13; As long as inserting under the state of valve 1, each fluid pressure line 12 get final product with attached 10 recess 11 hydraulic communication, thus the hydraulic fluid between fluid pressure line 12 and recess 11 to exchange be possible.This means that recess 11 has improved the versatility of valve 1.
Because being operatively connected between stop surface 5 and the opposite edges 6, the valve 1 that can insert valve actuating device and remove from valve actuating device with plain mode is provided.Thereby valve 1 can not only use as check mechanism but also as blocking device with the closing sequence controller.In this case; Piston 24 is replaced by the actuation member with closing sequence controller (not detailed icon); Or foundation can be by this actuating device of the valve actuating device startup that is associated with non-swing leaf; Therefore make the valve 1 of swing leaf that flowing of hydraulic fluid can maybe can not be carried out, thereby the valve actuating device that is associated with swing leaf of realization and braking or release.
As shown in Figure 1, on the direction of piston 24, to flow or flow in the opposite direction from the hydraulic fluid H of fluid pressure line 12, this being configured in being present in space 25 and the sliding part 3 between lining 2 and the sliding part 3 of flowing is that continuous through hole 3d carries out.Through hole 3d is used on the direction of recess 14 from exterior guiding hydraulic fluid H, or turns around.If piston 24 is in position shown in Figure 2, then possible is, its straightly against lining 2 with piston opposed outer surface 2f, make hydraulic fluid flowing in this zone be obstructed significantly or get clogged.For fear of this situation, according to Fig. 1, for example piston has through hole 24a, and through hole 24a sets about through hole 3d, makes hydraulic fluid H can flow through through hole 24a.Hydraulic fluid H passes flowing of piston 24 and representes through double-head arrow.
As selection; As shown in Figure 3; Piston 24 has the recess 24b of groove shapes; Laterally discharged from piston 24 through the recess 24b of this groove shapes from the hydraulic fluid H of through hole 3d, correspondingly the hydraulic fluid H from the side of piston 24 is directed to through hole 3d by recess 24b guiding and through recess 24b, as same represent with double-head arrow.
As selection, as shown in Figure 2 in the end towards piston 24, sliding part 3 has the recess 3e that is similar to recess 24b setting.In addition or as selecting, as shown in Figure 2 equally in the end towards piston 24, lining 2 also has and is similar to the recess 2g that recess 24b sets.The fluid stream that in this stub area, flows through sliding part 3 and lining 2 is represented by double-head arrow equally.This structure allows to be used to have the valve actuating device of the piston 24 of sealing fully, and this has widened application.
Particularly as see that in Fig. 1 attached 10 preferably has male screw portion 10e, be screwed into by means of this male screw portion 10e for attached 10 among the negative thread part 13c of structure complementally of housing 13 of door actuator.For this reason, attached 10 also preferably has bolt portion 10f, and this bolt portion 10f preferably has non-circular exterior contour, for example adopts outer-hexagonal shape shape.Thereby, can for example be screwed to housing 13 securely with attached 10 with plain mode through box spanner.This means that attached 10 is fixed on valve 1 in the door actuator, and bolt portion 15 makes valve can be suitable for door actuator together with lining 2, as described above.As further in Fig. 1 to Fig. 3, see, bolt portion 10f is in transversely having of the longitudinal axis L external dimensions bigger than the external dimensions of male screw portion 10e.Thereby, form abutting part, make bolt portion 10f can not too much move among the negative thread part 13c of housing 13, thereby attached 10 can not too much move in the housing 13.In addition, because only need being tightened, this bolt portion needn't consider virtually any size, so bolt portion 10f has simplified installation.
Fig. 4 shown according to the valve 1 of second embodiment of the invention with the similar sectional view of Fig. 1 to Fig. 3.This valve is different from the embodiment of front basically owing to the different back-moving springs of arranging 4.Spring with pre-tensioned state in the space 25 of vertical movable paths arrangement between valve body 3, lining 2 and bolt portion 15 away from the direction upper edge valve body 3 of bolt portion 15.This means, back-moving spring 4 same with valve body 3, be the opposite edges 6 that its stop surface 5 is pressed against lining 2.This means that spring fitting 17 and recess 2a and 3a can be removed.Therefore, valve body 3 and lining 2 can be configured to than before the variation described is remarkable must be short.The remainder of valve 1 is constructed according to above-described embodiment.For example, Fig. 4 has shown the structure according to Fig. 3.
Fig. 5 has shown the valve according to third embodiment of the invention.Like what seen, lining 2 is for example integrally constructed with bolt portion 15.Valve 1 has spring fitting 17, recess 2a and 3a and the back-moving spring 4 according to first embodiment of the invention, and correspondingly it alternatively also has distance members and according to the back-moving spring 4 of second embodiment of the invention.In the situation of extra back-moving spring 4, a little less than two back-moving springs 4 can both be configured to, maybe can increase the reset response power of its combination.In addition, owing to back-moving spring 4 is arranged in the space 25, so even second back-moving spring 4 will be removed or change, also there is basic homing action in the result.As long as it is adjustable that spring fitting 17 is set for, second back-moving spring 4 only is used for the fine adjustments of reset response power thus, and is for example illustrated in Fig. 5.
In addition, not bolt portion 15 but lining 2 is swirled to attached 10.In this case, in a side of the bolt portion dorsad 15 of seal 19, the attached 10 negative thread part 10g with at least one structure, lining 2 utilize male screw portion 2i to screw and get into negative thread part 10g.Advantage is that seal 16 is not pressed against on the screw thread with sealing means, but is pressed against on the smooth basically and flat inner surface, and this life-span for seal 16 has superiority.
The invention is not restricted to above-mentioned embodiment.
Attached 10 can with housing 13 unitary constructions, make valve 1 basically only by lining 2, valve body 3, back-moving spring 4 and the seal 16,18 that preferably exists and 19 and spring fitting 17 form.
