Description

阀及包括这种阀的用于涂覆覆盖产品的系统
【技术领域】
本发明涉及阀及包括这种阀的用于涂覆覆盖产品的系统。
【背景技术】
用于涂敷覆盖产品的系统，诸如喷涂器，包括至少一个阀，该阀控制可操纵为允许油漆循环的针。该阀通常通过将加压控制空气注入到腔室中来控制。加压空气作用在控制针的活塞上。这种阀包括密封装置，这些密封装置一方面防止油漆朝向腔室进入阀，另一方面防止加压的控制空气从腔室逸出并且防止其他流体进入腔室。
这种阀配备有排放口，即，通道，该通道使得可以在开始在油漆侧上的密封处泄漏的阀的情况下，将油漆引向喷漆器的外部，并且尤其是防止油漆进入控制空气回路，以保护阀门的控制部分。排放口还使得可以定位泄漏阀。
在一些当前的阀上，在阀的主体中进行穿孔，以将油漆引导到阀的外部，然后通过面向喷漆器主体并在其中钻出的点，引向喷油器的外部。
这种类型的排放口可能由于泄漏后的任意干燥油漆残留而导致对喷漆器的损坏，这些残留可能堵塞喷漆器主体中的排放口。
【发明内容】
本发明旨在通过提出一种用于涂敷覆盖产品的系统的新阀来解决这些缺点，在该阀上形成排放口，以便避免对用于涂敷覆盖产品的系统的损坏。
为此，本发明涉及一种用于涂敷覆盖产品的系统的阀，该阀包括主体，该主体包括内中心孔口和腔室，该阀还包括活塞，该活塞由安装在内孔口中的杆和安装在腔室中的活塞头形成，杆延伸到主体外部，并用于在涂敷系统的孔中移动，阀用于安装在该孔中，并且加压的覆盖产品或另外的流体在该孔中循环，阀包括第一密封装置，该第一密封装置由动态密封件形成，该动态密封件在阀的一侧上围绕活塞杆容纳在主体中，在阀的该侧，活塞杆延伸到主体外部，腔室的一部分用于填充有加压控制流体，以便获得抵抗容纳在主体中的弹簧的力的活塞的移动，阀包括第二密封装置，该第二密封装置由动态密封件形成，该动态密封件在第一密封装置与腔室之间围绕活塞杆容纳在主体中。该阀的特征在于：它包括排放管，该排放管设置在活塞的杆中，并且在第一密封装置与第二密封装置之间与内中心孔口连通，并且在露天或与露天连通的腔室的部分中露出。
由于本发明，阀的排放功能在阀内部执行。如果阀在油漆侧泄漏，那么足以更换阀，并且避免了已知排放口的问题，特别是涂敷系统的主体中的堵塞，这减少了维护操作。也降低了产品涂敷系统的总成本。
根据本发明的有利但可选方面，这种阀可以并入有以下特征中的一个或多个，这些特征以任意技术上可允许的组合来考虑：
-排放管包括至少一个径向孔口，该至少一个径向孔口在内中心孔口的腔中露出，该腔轴向地位于第一密封装置与第二密封装置之间。
-阀包括固定到活塞的指示器，该指示器被配置为基于活塞的位置突出到主体外部，并且排放管穿过指示器。
-排放管与活塞的中心轴线同轴。
-排放管在与露天连通且其中安装弹簧的腔室部分中露出。
-阀包括管道，该管道在主体的外表面与轴向地位于第一密封装置与第二密封装置之间的、内中心孔口的腔之间穿过主体，以便朝向排放管引导来自静态密封元件的泄漏，该静态密封元件插入主体与孔之间。
本发明还涉及一种包括如上所述的阀的覆盖产品的涂敷系统。

【具体实施方式】
图1示出了用于涂覆覆盖产品的系统2的一部分，例如，用于油漆、清漆、防腐覆盖物或任何其他可想到类型的产品的喷涂器。系统2包括安装在系统2的孔6中的阀4。
阀4包括主体8，该主体包括内中心孔口10和腔室12。孔口10和腔室12以中心轴线X为中心。在下文中，术语“轴向的”、“径向的”、“轴向地”、“径向地”参考中心轴线X来使用。
孔口10和腔室12流体连通。孔口10在孔6中在主体8的端面14处从主体8露出。
系统2包括在孔6中的流体进入管道16和延伸穿过孔6的流体排出管道18。在一些应用中，进入管道和排出管道可以颠倒。进入管道16和排出管道18主要用于覆盖产品的循环，但是其他流体，尤其是空气或清洁溶剂，也可以在进入管道16和排出管道18中循环。
在进入管道16与排出管道18之间，孔6包括座20，阀4的针22与该座20协作，以便封闭或允许覆盖产品沿着箭头F1从进入管道16到排出管道18的循环。在未示出的变型中，座20也可以直接在涂覆系统2的材料中加工。进入管道16连接到未示出的覆盖产品储存器或者泵，特别是“循环”类型的泵，并且排出管道18连接到未示出的涂敷或喷涂装置，诸如喷枪。
阀4包括由安装在内孔口10中的杆240和容纳在腔室12中的活塞头242形成的活塞24。杆240延伸到主体8的外部并支承针22。杆240旨在在孔6中沿着中心轴线X平移，加压的覆盖产品在孔6中沿着箭头F1循环。
阀4包括第一密封装置26，该第一密封装置在阀4的一侧上围绕活塞杆240容纳在主体8中，在阀4的该侧上，杆240延伸到主体8外部。第一密封装置26是动态密封件，该动态密封件使得可以防止覆盖产品在活塞杆240的平移移动期间朝向腔室12在活塞杆240与主体8之间渗透。
活塞头242具有垂直于中心轴线X的轴向表面244。活塞头242在裙部246中径向地延伸，裙部246中容纳有密封装置248，该密封装置248确保在活塞头242在腔室12中的平移移动期间，活塞头242与腔室12的内圆柱壁120之间的动态密封。密封装置246将腔室12分成流体隔离的两部分12A和12B，这是因为密封装置246防止流体在部分12A与12B之间围绕活塞头242循环。
腔室12的部分12A位于活塞杆240的侧面。轴向表面244位于部分12A中。喷涂系统2包括用于加压控制流体的进入管道28，该进入管道在主体8的周边凹槽30中出现。周边凹槽30通过轴向孔口32与部分12A连通。腔室12的部分12A用于填充有加压控制流体，例如，空气，以便控制活塞24的轴向移动。阀4包括安装在腔室12的部分12B中的弹簧34。弹簧34以中心轴线X为中心，并且对活塞头242施加弹性力，以便将其向下驱动，也就是说，将其推入到部分12A中。弹簧34抵靠活塞头242的一部分并且抵靠在阀4的塞子36上，该塞子被紧固到主体8并且拧紧在涂敷系统2中。
在经由管道28注入到部分12A中的压缩空气的控制作用下(箭头F2)，活塞24抵抗弹簧34的力通过由加压空气的压力对轴向表面244施加的力向上移动(箭头F3)。这导致将针22提离座20并允许覆盖产品通向排出管道18。
阀4包括第二密封装置38，该第二密封装置在第一密封装置26与腔室12之间围绕活塞杆240容纳在主体8中。该密封装置38是动态密封件，该动态密封件防止空气在活塞杆240的平移期间离开腔室12，而且防止其他流体进入部分12A，必须使加压控制空气回路免于外部流体(特别是覆盖产品)的任何侵入。
阀4还包括若干静态密封装置，它们确保孔6与主体8之间的紧密性。这些装置由容纳在主体8的凹槽中并抵靠孔6的O形环39形成，特别是确保围绕端面14在孔6与主体8之间的紧密性的O形环。
在第一密封装置26发生可能引起泄漏以及覆盖产品朝向腔室12的流入的故障的情况下，阀4包括排放管40，该排放管使得可以将已经泄漏的覆盖产品朝向与腔室12的部分12A分开的位置排出。
排放管40设置在活塞杆240中，并且与第一密封装置26和第二密封装置38之间的内中心孔口10连通，并且在露天或与露天连通的腔室12的部分中露出。排放管40由包围在形成活塞杆240的材料中的管道形成。由此，通气孔40设置在阀4本身中，这在涂敷系统2中不需要通气通道。无需干预涂敷系统即可更换有缺陷的阀。
在一个实施方式中，排放管40与活塞24的中心轴线X同轴。排放管40包括至少一个径向孔口42，该至少一个径向孔口在内中心孔口10的腔44中露出，该腔轴向地位于第一密封装置26与第二密封装置38之间。由此，穿过第一密封装置26的覆盖产品的任何泄漏都累积在腔44中，然后沿着箭头F4经由径向孔口42重新接合到排放管40。排放管40可以包括围绕中心轴线X分布的若干径向孔口42。
阀4包括指示器46，该指示器46由固定到活塞24的部分形成，并且被配置为基于活塞24的轴向位置突出到主体8的外部。指示器46是圆柱形部分，该圆柱形部分与中心轴线X同轴，被紧固到活塞头242，并且插入到塞子36的孔360中。当在压缩控制空气的作用下将活塞24向上推时，指示器46突出到塞子36的外部，并且从外部可见。
在所例示的示例中，排放管40在穿过指示器46的穿孔460中延伸，因此，已经通过排放管40泄漏的覆盖产品沿着箭头F4排出到露天地方。因此，如果第一密封装置26出故障，则覆盖产品泄漏通过活塞杆240、然后指示器46(即，阀4的部件)排出到露天地方，而不通过喷涂装置2。这不需要在泄漏的情况下必须清洁的特殊阀。此外，覆盖产品经由通气孔40定向为远离部分12A，以防止污染控制空气回路。
根据未示出的一种变型，排放管40不能与中心轴线X同轴。
根据图2所示的另一变型，排放管40不能穿过指示器46，以便将覆盖产品排出到露天地方。例如，排放管40可以通过管道400遵循活塞杆240和活塞头242内部的路径，这些管道400在腔室12的部分12B中露出。部分12B经由塞子36的孔360与露天连通，指示器46沿着中心轴线X滑动通过孔360。因此，覆盖产品可以经由孔360从部分12B排出。一定量泄漏的覆盖产品可以累积在指示器46和弹簧34周围，并且有利地将阀4堵塞在关闭位置。部分12A通过动态密封装置248保持免受覆盖产品泄漏的影响。阀4在关闭位置的堵塞导致迅速指示阀4的故障。
根据未示出的变型，指示器46也可以不与中心轴线X同轴。指示器46也可以不是与活塞24分开的部分。指示器和活塞24可以是一体的并且形成自始至终被径向孔口42与塞子36处的露天地方之间的排放管40通过的整体部分。
根据一个可选方面，阀4可以包括在孔6与腔44之间穿过主体8的穿孔500。穿孔500的开口相对于端面14设置在密封件39A的后面。由此，在密封件39A处出现密封问题的情况下，在主体8的外表面与孔6之间的泄漏通过穿孔500引导并且沿着箭头F5朝向腔44且然后朝向径向孔口42和排放管40定向。
参见图3至图9，描述了阀4的另外方面、用于组装和拆卸阀4的工具52以及该工具52的操作。
阀4包括在周边部分上的突出或凹进形状，该突出或凹进形状被配置为与工具52的突出或凹进形状协作。这些突出或凹进形状被配置为将旋转移动传递到阀4，并在阀4的拆卸期间固定到工具52。周边部分由具有图4所示的特定形状的塞子54形成，并且该塞子的主要功能类似于图1的塞子36的功能：塞子54被紧固到主体8并拧紧在涂敷系统2中。为此，塞子54包括外螺纹540。
设置在塞子54上的突出或中空形状包括周边轮廓542和周边轮廓544，该周边轮廓544相对于阀4的外端546位于周边轮廓542的后面，该外端由塞子54的轴向表面支承。周边轮廓542和544沿着轴线X分级，周边轮廓542最靠近端546。
周边轮廓542具有三个平坦表面542A，这些表面平行于轴线X延伸，并且形成了塞子54的圆柱形状的断裂。周边轮廓544包括与周边轮廓542的三个平坦表面542A对齐的三个平坦表面544A以及相对于三个平坦表面542A成角度地偏移的三个平坦表面544B。“对齐”意指平坦表面544A至少部分地位于沿着平坦表面542A的轴线X的延伸中并形成相同的平面。“成角度地偏移”意指表面544B位于相对于平坦表面542A在其中延伸的角扇区偏移的角扇区中，使得由平坦表面542A和544B形成的各个平面是正割的。该角偏移使得平坦表面544B可以形成相对于周边轮廓542凹进的轴向肩部545。如图4所示，平坦表面544B从周边轮廓542的圆柱部分退回。
工具52包括在周边部分上的突出或凹进形状，该形状被配置为与设置在阀4的塞子上的突出或凹进形状协作。工具52的这些突出或凹进形状被配置为在阀4的组装或拆卸期间，将旋转移动传递到阀4并固定到阀4。
工具52沿着中心轴线X52延伸，并且包括手柄520和具有孔524的端件522。工具52的突出或中空形状设置在孔524的内周面524A上。内周面524A包括三个平坦的周边表面526，其等于阀4的周边轮廓542的平坦表面542A的数量。平坦表面526以与表面542A平行于轴线X相同的方式平行于轴线X52。周边表面524A还包括从平坦的周边表面526径向地退回的凹槽528。凹槽528相对于工具52的前端530位于平坦表面526的后面。凹槽528形成轴向的肩部527，该肩部被配置为通过固定阀4与工具52来接收阀4的一部分。
凹槽528包括弹性元件529，当阀4被接收在工具52中时，该弹性元件529针对阀4的被接收在凹槽528中的部分施加沿着轴线X52定向的弹性力。该弹性元件529可以例如是O形环。在未示出的变型中，该弹性元件也可以是螺旋弹簧或锁紧垫圈(贝氏垫圈)。
在未示出的变型中，周边轮廓542可以包括不同数量的平坦表面，更通常地，至少一个平坦表面。同样地，周边轮廓544可以具有与周边轮廓542的平坦表面对齐的若干个平坦表面(其数量不同于三个，更通常是至少一个)和相对于周边轮廓542的平坦表面成角度偏移的至少一个平坦表面。如同周边轮廓542和544的平坦表面一样，工具52可以具有数量不同于三个的平坦表面526，更通常是至少一个平坦表面。
下文将描述具有阀4的工具52的操作。图5、图6以及图7示出了阀4在其壳体中的组装。将阀4定位在其孔6中，然后使工具52更靠近阀4，使得轴线X和X52被组合(图5)。
当将端件522推入到塞子54中(图6)使得周边轮廓542至少部分地与平坦表面526轴向对齐时，平坦表面542A和544A通过与平坦表面526平面接触来协作(图7，其中省略了弹性元件529)。因此，通过沿着箭头R1向工具52给予旋转拧紧移动，操作者可以将阀4拧入孔6中。
当操作者希望拧开阀4并去除阀时，他将工具52更深地推入，使得弹性元件529被压碎。周边轮廓542与凹槽528轴向对齐(图9)。接下来，操作者沿着箭头R2在拧开方向上施加旋转，使得表面526绕轴线X枢转，直到它们与平坦表面544B平面接触为止(图8)。该旋转由以下事实允许：周边轮廓544在平坦表面544A和544B的交界处具有允许在拧开方向上旋转的磨圆表面544C。
在这种配置中，通过将工具52的平坦表面526插入到由周边轮廓544形成的退回的凸起中，将周边轮廓542堵塞在凹槽528中。然后，工具52的肩部527在轴向上与阀4的肩部545相对，并且防止工具52从阀4去除。由弹性元件529施加的弹性力趋向于将阀4推回到孔544外部，因此，锁定肩部527和545之间的接触。阀4和工具52然后形成一体组件。阀4和工具52形成“卡口”组件。
通过继续沿拧开方向旋转，操作者在表面526和544B之间施加平面接触，该接触使得可以拧开阀4。一旦将阀从孔6拧出，就可以轻松地去除阀4，即使是从难以到达的位置，因为阀4保持附接至工具52的端件522。阀4保持固定至工具52且不存在掉落的风险。
在将阀4组装在难以到达的位置期间，也可以使用将阀4附接到端件522的这种可能性。操作者可以在组装之前通过将阀4推入孔524中且然后沿拧开方向转动阀4来将阀4紧固到工具52。在将阀4安装在其孔6中之后，操作者然后沿拧紧方向转动工具52。然后，阀4将自由旋转并自行拧紧，直到拧紧遇到阻力为止。然后，工具52的旋转扭矩克服由弹性元件施加的力，并且工具52相对于阀4旋转，直到获得表面526与表面542A和544A的协作为止。然后可以继续拧紧，直到锁定为止。
因此，工具52和设置在阀4上的凹进/突出的凸起使得可以使用相同的工具来组装和拆卸阀。如果允许组装和拆卸的装置都设置在工具52的同一端件522上，则不必旋转它以便执行任何一种操作。通过卡口组件固定阀4和工具52的可能性使得可以在难以到达的位置容易地组装或拆卸阀4。与已知的技术不同，阀的拧开及其去除尤其可以在单个操作中进行，在已知的技术中，用两种不同的工具进行拧开和去除，如果阀门未充分拧开，则两种工具有时需要繁重的更换。
在权利要求的上下文中，可以组合上述实施方式和另选方案的特征，以形成本发明的新实施方式。
