Description
本發明涉及一種葉片式節流閥。 The invention relates to a vane type throttle valve.
習知的葉片式節流閥包括複數平板狀的葉片,通過旋轉葉片改變葉片的傾斜角度來調節節流閥的開關角度,然而隨著節流閥尺寸的增大,僅僅通過旋轉葉片來調節節流閥開關的角度無法精確控制流體的流量,特別對於真空鍍膜設備,節流閥的尺寸越大則越是造成氣體的浪費,而且越是難以控制設備內的真空度。 The conventional vane type throttle valve includes a plurality of flat blades, and the switching angle of the throttle valve is adjusted by changing the inclination angle of the blades by rotating the blades. However, as the size of the throttle valve increases, the section is adjusted only by rotating the blades. The angle of the flow valve switch does not accurately control the flow of the fluid. Especially for vacuum coating equipment, the larger the size of the throttle valve, the more waste of gas, and the more difficult it is to control the vacuum inside the equipment.
有鑒於此,有必要提供一種能精確控制開關角度的葉片式節流閥。 In view of this, it is necessary to provide a vane type throttle valve that can precisely control the switching angle.
一種葉片式節流閥,包括複數葉片,每一葉片上均設有至少一通孔,每一葉片上可滑動地連接一擋板,該擋板上設有與葉片上的通孔相應的穿孔,所述擋板相對葉片滑動以調節葉片上通孔的開關程度。 A vane type throttle valve includes a plurality of vanes, each of which is provided with at least one through hole, each of which is slidably connected to a baffle, and the baffle is provided with a perforation corresponding to the through hole in the vane, The baffle slides relative to the blade to adjust the degree of switching of the through hole in the blade.
與習知技術相比,該葉片式節流閥可通過擋板與葉片的相對滑動調節葉片上通孔的開關程度,從而可精確控制通過葉片式節流閥的流體的流量,節省流體。 Compared with the prior art, the vane type throttle valve can adjust the degree of opening and closing of the through hole on the vane by the relative sliding of the baffle and the vane, thereby accurately controlling the flow of the fluid through the vane type throttle valve and saving the fluid.

如圖1所示,本發明一較佳實施例的葉片式節流閥包括一殼體10、設置於殼體10內的複數葉片30及複數擋板50。 As shown in FIG. 1, a vane type throttle valve according to a preferred embodiment of the present invention includes a housing 10, a plurality of vanes 30 disposed in the housing 10, and a plurality of baffles 50.
所述葉片30的數量可以根據需要而改變,本實施例中,為簡化圖示,僅示出五個葉片30。所述葉片30均勻間隔設置,且通過一連接件70連接為一體,該連接件70包括一縱長的連接桿72以及複數可轉動地連接於連接桿72上的連接片74,連接片74的數量是根據葉片30的數量設置,每一連接片74連接於一葉片30的上表面上,連接片74與葉片30的連接方式可以是黏貼、焊接等。 The number of the blades 30 can be changed as needed, and in the present embodiment, only five blades 30 are shown for simplicity of illustration. The blades 30 are evenly spaced and integrally connected by a connecting member 70. The connecting member 70 includes an elongated connecting rod 72 and a plurality of connecting pieces 74 rotatably connected to the connecting rod 72. The number is set according to the number of the blades 30, and each of the connecting pieces 74 is connected to the upper surface of one of the blades 30, and the connecting piece 74 and the blade 30 may be attached by adhesion, welding or the like.
每一葉片30均呈薄板狀,葉片30上設有複數貫穿葉片30的通孔32,所述通孔32大致均勻地分佈於葉片30上。葉片30的兩端分別形成一支撐軸38,所述支撐軸38固定連接於殼體10的相對兩壁面上,葉片30與支撐軸38之間形成轉動連接。其中位於中間的葉片30可連接一轉動驅動件,從而驅動葉片30旋轉,調節葉片30開關的角度。由於連接件70將所有葉片30連接為一體,當旋轉驅動件驅動中間的葉片30旋轉時,可帶動所有的葉片30同步旋轉。 Each of the vanes 30 has a thin plate shape, and the vane 30 is provided with a plurality of through holes 32 penetrating the vanes 30, and the through holes 32 are substantially uniformly distributed on the vanes 30. The two ends of the blade 30 respectively form a support shaft 38. The support shaft 38 is fixedly coupled to the opposite wall surfaces of the housing 10, and the blade 30 forms a rotational connection with the support shaft 38. The blade 30 located in the middle is connectable to a rotary drive member to drive the blade 30 to rotate, adjusting the angle of the switch of the blade 30. Since the connecting member 70 connects all the blades 30 as one body, when the rotating driving member drives the intermediate blades 30 to rotate, all the blades 30 can be driven to rotate synchronously.
每一葉片30的下表面上貼設一擋板50,每一擋板50上設有複數貫穿擋板50的穿孔52,所述穿孔52的數量、位置、大小與葉片30上 通孔32的數量、位置、大小相同。所述擋板50連接為一體,其連接方式與葉片30的連接方式相似,本實施例中,通過一固定件90連接為一體,該固定件90包括一縱長的固定桿92以及複數可轉動地連接於固定桿92上的固定片94,所述固定片94分別與擋板50的一下表面連接從而將所有擋板50連接為一體。 A baffle 50 is disposed on the lower surface of each of the blades 30, and each of the baffles 50 is provided with a plurality of through holes 52 penetrating the baffle 50. The number, position and size of the perforations 52 are on the blade 30. The number, position, and size of the through holes 32 are the same. The baffle 50 is integrally connected, and the connection manner is similar to that of the blade 30. In this embodiment, the baffle 50 is integrally connected by a fixing member 90. The fixing member 90 includes an elongated fixing rod 92 and a plurality of rotating members. The fixing pieces 94 are connected to the fixing rods 92, and the fixing pieces 94 are respectively connected to the lower surface of the baffle 50 to integrally connect all the baffles 50.
如圖3所示,擋板50與相應的葉片30之間形成滑動連接,本實施例中,葉片30的下表面向內凹陷形成兩滑槽34,擋板50上表面向外凸設形成與滑槽34配合的兩凸條54。為避免對葉片30上的通孔32的影響,葉片30上的兩滑槽34分設於通孔32的兩側,相應地,擋板50上的凸條54也分設於穿孔52的兩側。其中滑槽34的深度小於葉片30的厚度,並未在厚度方向上貫穿葉片30,滑槽34的橫截面大致呈梯形,滑槽34的寬度由外向內逐漸遞減,也就是說,滑槽34在葉片30的下表面處最窄。而凸條54的高度不大於滑槽34的深度,優選地,本實施例中,凸條54的高度與滑槽34的深度相當。凸條54的橫截面為梯形,上寬下窄,凸條54的頂端的寬度與滑槽34的最大寬度相當,大於滑槽34位於葉片30的下表面處的寬度,凸條54與擋板50的連接處的寬度大致與滑槽34位於葉片30的下表面處的寬度相當。擋板50連接於葉片30上時,該兩凸條54可滑動地收容於葉片30的兩滑槽34內,由於滑槽34的寬度限制,凸條54不會由滑槽34中脫落,凸條54與滑槽34構成卡扣連接,將擋板50穩定地連接至葉片30上。可以理解地,葉片30的滑槽34與擋板50的凸條54形成卡扣配合是為了將擋板50連接至葉片30上,也可將滑槽34設置於擋板50上,而凸條54設置於葉片30上,從而組裝後葉片30上的凸條54卡扣於擋板50的滑槽34內將兩者連接為一體。凸條54與滑槽34的形狀也不限於上述的梯形。 As shown in FIG. 3, a sliding connection is formed between the baffle 50 and the corresponding blade 30. In this embodiment, the lower surface of the blade 30 is recessed inwardly to form two sliding slots 34. The upper surface of the baffle 50 is convexly formed outwardly. Two ribs 54 that cooperate with the chute 34. In order to avoid the influence of the through holes 32 on the blade 30, the two sliding grooves 34 on the blade 30 are disposed on both sides of the through hole 32. Accordingly, the ribs 54 on the baffle 50 are also divided into two of the through holes 52. side. The depth of the sliding groove 34 is smaller than the thickness of the blade 30, and does not penetrate the blade 30 in the thickness direction. The cross section of the sliding groove 34 is substantially trapezoidal, and the width of the sliding groove 34 gradually decreases from the outside to the inside, that is, the sliding groove 34 It is the narrowest at the lower surface of the blade 30. The height of the ridge 54 is not greater than the depth of the chute 34. Preferably, in the present embodiment, the height of the rib 54 is comparable to the depth of the chute 34. The rib 54 has a trapezoidal cross section, the upper width is narrower, and the width of the top end of the rib 54 is equivalent to the maximum width of the sliding groove 34, which is larger than the width of the sliding groove 34 at the lower surface of the blade 30, the ridge 54 and the baffle. The width of the junction of 50 is substantially equivalent to the width of the chute 34 at the lower surface of the blade 30. When the baffle 50 is connected to the blade 30, the two ribs 54 are slidably received in the two sliding slots 34 of the blade 30. Due to the limitation of the width of the sliding slot 34, the ridge 54 is not detached from the sliding slot 34, and is convex. The strip 54 forms a snap connection with the chute 34 to stably connect the baffle 50 to the blade 30. It can be understood that the sliding groove 34 of the blade 30 forms a snap fit with the rib 54 of the baffle 50 in order to connect the baffle 50 to the blade 30, and the chute 34 can also be disposed on the baffle 50, and the rib 54 is disposed on the blade 30 such that the ridges 54 on the assembled blade 30 are snapped into the slots 34 of the baffle 50 to connect the two together. The shape of the ridge 54 and the chute 34 is not limited to the trapezoid described above.
其中位於中間的一擋板50,即貼靠於中間的葉片30上的擋板50,對應於設有轉動驅動件的一端,用於連接一滑動驅動件,該滑動驅動件可驅動中間的擋板50相對葉片30滑動,進而帶動所有擋板50一起相對葉片30滑動。 A baffle 50 located in the middle, that is, a baffle 50 abutting against the intermediate blade 30, corresponding to one end provided with a rotary driving member for connecting a sliding driving member, the sliding driving member can drive the intermediate block The plate 50 slides relative to the blade 30, which in turn drives all of the baffles 50 to slide relative to the blade 30.
圖1所示為葉片30處於完全打開的狀態,此時所有葉片30相互平行,均呈水平狀,擋板50貼合於相應的葉片30的下方,與葉片30完全重疊。相鄰兩葉片30之間形成一通道36,供流體通過,該通道36的高度不大於葉片30的寬度,優選地,葉片30的寬度略大於通道36的高度。連接件70設置於葉片30的後側,固定件90設置於葉片30的前側,當啟動轉動驅動件來調整葉片30的角度時,葉片30以及連接件70的連接片94以支撐軸38為中心軸沿順時針方向轉動,與此同時,連接在葉片30上的擋板50以及固定件90的固定片94同步沿順時針方向轉動,逐步將葉片30之間的通道36關閉。當所有葉片30轉動至大至豎直狀態,由於葉片30的寬度大於葉片30水平時葉片30之間的通道36的高度,此時相鄰的葉片30部分重疊,所有葉片30共同形成一連續的壁面,葉片30處於封閉狀態。請參閱圖2,由於葉片30上設有通孔32,擋板50上設有穿孔52,而此時擋板50與葉片30重疊,擋板50上的穿孔52與葉片30上的通孔32分別連通,可供少量的流體流通,也就是說當葉片30旋轉至封閉狀態時,通道36並未完全封閉,仍然可供少量流體流通,相當於減小了通道36的大小。 1 shows the blade 30 in a fully open state, in which all the blades 30 are parallel to each other and are horizontal, and the baffle 50 is fitted under the corresponding blade 30 to completely overlap the blade 30. A passage 36 is formed between adjacent two vanes 30 for fluid passage therethrough. The height of the passage 36 is no greater than the width of the vane 30. Preferably, the width of the vane 30 is slightly greater than the height of the passage 36. The connecting member 70 is disposed on the rear side of the blade 30, and the fixing member 90 is disposed on the front side of the blade 30. When the rotational driving member is activated to adjust the angle of the blade 30, the blade 30 and the connecting piece 94 of the connecting member 70 are centered on the supporting shaft 38. The shaft is rotated in the clockwise direction, at the same time, the baffle 50 attached to the blade 30 and the fixing piece 94 of the fixing member 90 are synchronously rotated in the clockwise direction to gradually close the passage 36 between the blades 30. When all of the blades 30 are rotated to a large vertical state, since the width of the blades 30 is greater than the height of the passages 36 between the blades 30 when the blades 30 are horizontal, the adjacent blades 30 partially overlap, and all the blades 30 together form a continuous On the wall, the blade 30 is in a closed state. Referring to FIG. 2, since the blade 30 is provided with a through hole 32, the baffle 50 is provided with a through hole 52, and at this time, the baffle 50 overlaps the blade 30, and the through hole 52 on the baffle 50 and the through hole 32 in the blade 30 are provided. Connected separately, a small amount of fluid can be circulated, that is, when the blade 30 is rotated to the closed state, the passage 36 is not completely closed, and a small amount of fluid is still circulated, which is equivalent to reducing the size of the passage 36.
如圖3所示,當需要進一步減小流體的流量時,可啟動滑動驅動件從而驅動擋板50相對葉片30滑動,隨著擋板50的移動,擋板50上的穿孔52偏離葉片30上的通孔32,葉片30的通孔32逐漸被擋板 50遮擋,同時擋板50上的穿孔52也逐漸被葉片30上的穿孔52遮擋,穿孔52與通孔32重疊的部分逐漸減小,也就是說可供流體流通的通道36越來越小,如圖4所示,當擋板50滑動至穿孔52完全偏離葉片30上的通孔32時,葉片30的通孔32完全被擋板50遮擋,同時擋板50上的穿孔52也完全被葉片30上的穿孔52遮擋,此時通道36被完全封閉,限制流體的流通,也就是說,葉片式節流閥整體處於完全封閉狀態。 As shown in FIG. 3, when it is desired to further reduce the flow rate of the fluid, the slide drive member can be activated to drive the shutter 50 to slide relative to the blade 30. As the shutter 50 moves, the perforation 52 on the shutter 50 is offset from the blade 30. Through hole 32, the through hole 32 of the blade 30 is gradually blocked by the baffle 50 is blocked, and the perforations 52 on the baffle 50 are also gradually blocked by the perforations 52 on the vanes 30, and the portion of the perforations 52 overlapping the through holes 32 is gradually reduced, that is, the passage 36 through which the fluid can flow is smaller and smaller. As shown in FIG. 4, when the baffle 50 slides until the perforation 52 is completely offset from the through hole 32 in the blade 30, the through hole 32 of the vane 30 is completely blocked by the baffle 50, while the perforation 52 on the baffle 50 is also completely covered by the vane. The perforations 52 in the 30 are blocked, at which point the passage 36 is completely closed, restricting the flow of fluid, that is, the vane type throttle is entirely closed.
從而,該葉片式節流閥可通過滑動擋板50逐步調節葉片30上通孔32的開關程度,逐步調節流體的流量,從而可精確控制流體流量的流量,避免流體的浪費,對於真空鍍膜設備而言,由於該葉片式節流閥可逐步調節流體的流量,從而可以儘量將設備內的氣體抽出,達到較高的真空度。 Therefore, the vane type throttle valve can gradually adjust the degree of switching of the through hole 32 on the vane 30 through the sliding baffle 50, and gradually adjust the flow rate of the fluid, thereby precisely controlling the flow rate of the fluid flow and avoiding waste of the fluid, for the vacuum coating equipment. In this case, since the vane type throttle valve can gradually adjust the flow rate of the fluid, the gas in the apparatus can be extracted as much as possible to achieve a high degree of vacuum.
