Abstract

一种喷枪，用于混合并喷射两种介质，其包含用于每一种介质的阀。所述两个阀一个设置在另一个里面，并且可以在一个壳体中轴向位移、彼此相对移动，克服弹簧作用力，向着或离开一个阀座移动。上述阀一起受到外部力的作用。

Description

喷枪
本发明涉及一种喷枪，其用于混合并喷射两种介质，并且包含用于每一种介质的一个阀。
上述喷枪已经众所周知，其具有两个分开的阀及一公共的混合室，两个分开的阀分别用于每一种介质并彼此隔开一定距离。这种设计的缺点在于，当两种介质相互反应时，阀孔将被堵塞；为防止这种情况发生，在每次喷射操作的中断期间都需要仔细地清洗。另一缺点在于，喷枪变得非常庞大，从而难于握持；并且具有许多可移动部件，从而与只用于一种介质的喷枪相比，需要更多维护，造价昂贵。
本发明的目的是提供一种喷枪，其具有以下优点：
通过擦拭，易于清洗；
在很大程度上防止了污染阀孔；
如同用于一种介质的喷枪一样易于握持；
具有很少的移动部件；
需要极少地维护；
价格合理。
通过下述设计解决了上述任务，其中，使用了两个阀，一个阀在另一个阀里面；所述阀可以在一个壳体中移动、彼此相对移动以及克服弹簧作用力向着或离开阀座运动；通过一外部作用力使阀被驱动。
参照附图，以实施例的方式对本发明进行更详细地说明。
图1为本发明喷枪处于关闭的不工作状态时的截面图；
图2为通过本发明喷枪中部的放大截面图，喷枪处于动作位置；
圈2a为图2中用圆圈2a标出部分的局部放大图；
图2b为图2中用圆圈2b标出部分的局部放大图。
根据本发明的喷枪包括，一中央壳体11，中央壳体的前部装配有喷嘴12，后部装配有伺服机构13。中央壳体11包含两个阀14和15，其中内阀15设置在外阀14中。壳体11还包含手柄16，和手柄16前面的扳机17，其形式为双臂杆，并可绕销轴18转动。在壳体上部设置了用于控制伺服机构13的阀装置19。
外阀14可以在壳体11中轴向移动，并包括，套筒20，套筒20延伸到同轴的筒管21，而筒管21延伸进入喷嘴12。一保护衬套22螺纹连接在筒管21上，其向前的锥形端23与壳体11中的阀座24配合。在筒管的前端设置了止回阀25，该止回阀在筒管中压力的作用下可以打开。保护衬套22外面包围着一环形通道30，该环形通道30与供给管道31连通，用来供应第一介质，例如，聚酯。在筒管21和套筒20之间的过度段，在套筒20中设置有阀座26，该阀座与内阀15的阀体27的端面配合作用。内阀由一个筒管28构成，其前端封闭，但是设有侧向开口29，通过该开口与第二环形通道或第二环形槽32连通，当阀体27在离开其阀座26的方向上位移使通道33的开口暴露出来时，第二环形通道32与筒管21的内通道33连通。
可以在外阀14的套筒20中轴向位移的内阀15，通过其管状阀体28进入套管34，所述套管在套筒20中被引导。筒管28的内通道36在此套管处开口；用于供应第二介质，例如，硬化剂的供给管道37连接于该通道。活塞40的活塞杆39构成了伺服机构13的一部分，并受到加压弹簧38的负载；该活塞杆也连接在套管34上。
压力空气管道35与壳体11连接，其向阀杆41提供压力空气；所述阀杆41装配有两个阀体42和43，其中一个总是靠在一阀座上保持封闭状态，而另一个处于开启状态。阀杆的位置由扳机17控制。当扳机被动作时，阀体42打开连着空气管道44的通道，从而将压力空气导入活塞40的前侧。活塞杆39于是受到克服弹簧38的作用力的拉力。该拉力被传递到套管34，从而使由外、内阀14和15构成的整个阀组件向着一挡块46位移，如图2和2a所示。在此阶段，因为在第二环形槽32和通道36中包含的第二介质受到压力作用，两个阀14、15形成一个互相连接的装置。在此位置，超出阀座24的通道开通，这样第一介质能够从供给管道31流到喷嘴12的连接通道45。这个通道设计为混合室或混合通道，其装配有例如螺旋状的混合元件。
随着压力空气连续供应到活塞40，超出阀座26的通道将被打开，这样，第二介质能够从环形槽32流入到筒管21的内通道33，并进一步流到止回阀25，使之打开。于是，第二介质抵达混合室45，开始两种介质的混合。
当在止回阀25处的用于第二介质的出口位于用于第一介质的在标号24处的出口前面时，第一介质总是先被排放，在这些出口24处不会有任何污染。在拧下喷嘴12后，清洗仅限于擦拭止回阀25。
