QUETSCHVENTILPINCH VALVE
Quetschventlle slnti altbekannte und zuverlässig arbeitende Absperrorgane für Rohrleitungen. Die Arbeitswelse ist einfach: Ein elastischer Quetschventilschlauch wird von einem Steuermittel, z.B. Druckluft oder einer Hydraulikflüssigkeit, so zusammengedrückt, daß der Durchfluß in dem Quetschventilschlauch gesperrt ist·Pinch valves are well-known and reliably working shut-off devices for pipelines. The working catfish is simple: An elastic pinch valve hose is compressed by a control means, e.g. compressed air or a hydraulic fluid, so that the flow in the The pinch valve hose is blocked Herkömmliche Quetechventile haben etwa folgenden Aufbau: In einem Ventilgehäuse wird ein zylindrische^ Quetschveiitilschlauch an seinen beiden Enden mit jeweils einem losen Flansch, der ein schlauchtüllenähnliches Anpreßteil enthält, durch Einpressen in den jeweiligen Ventilgehäuseflansch, der eine konische Ausdrehung enthält, befestigt. Die Quetschventilschläuche sind dadurch an ihren Einpreßstellen bereits im Ruhestand erheblichen Spannungen ausgesetzt. Durch die Lastwechsol während des Betriebes solcher Quetschventile sind die Quetschventilschläuche an diesen Einpreßstellen zusätzlich erheblichen Walk- und Biegespannungen unterworfen.Conventional pinch valves have the following structure: In a valve housing a cylindrical squeeze tube is attached to both ends with a loose tube Flange, which contains a hose-spout-like pressing part, is fastened by being pressed into the respective valve housing flange, which contains a conical recess. As a result, the pinch valve hoses are exposed to considerable stresses at their press-fit points even in retirement. Due to the load changes during operation of such Pinch valves are the pinch valve hoses on them Press-fit points are also subjected to considerable flexing and bending stresses.
Im Dauerbetrieb neigen dadurch die Quetschventilschläuche dazu, an ihren Einpreßstellen am ehesten zu Bruch zu gehen.In continuous operation, the pinch valve hoses tend to break at their press-fit points.
Der Fortschritt des neuen Quetechventile besteht nur im wesentlichen darin, daß der Quetschventilschlauch 6 in dem Ventilgehäuse, daß in einzelnen aus dem Gehäusemantel 1, dem G-ehäuseflanech 3» dem Befestigungsflansch k und dem Gehäueeflansch 5 besteht, nicht mehl; durch Einpressen befestigt wird·The progress of the new pinch valve consists essentially in the fact that the pinch valve hose 6 in the valve housing, which consists of the housing jacket 1, the housing flange 3, the fastening flange k and the housing flange 5, does not fail; is fastened by pressing in
Um das zu erreichen, enthält der Quetschventilschlauch 6 an seinen Enden kegeletutzenförmige Wülste 7» In denen kegele tutsenförmige Metallringe 8 einvulkanisiert sind. Mit Hilfe der Innensechskantschrauben 9, die ihr Gegengewinde in den Metallringen 8 haben, werden die Wülste 7 des Quotschventilschlauches 6 gegen die Innenflächen 12 der Gehäuseflansche 3 und 5 gezogen und damit befestigt; wie in Pig.1 dargestellt.To achieve this, the pinch valve hose contains 6 at its ends, conical socket-shaped beads 7 »in which conical tube-shaped metal rings 8 are vulcanized. With The help of the Allen screws 9, which have their mating thread in the metal rings 8, the beads 7 of the Quotsch valve hose 6 drawn against the inner surfaces 12 of the housing flanges 3 and 5 and thus fastened; as in Pig. 1 shown.

Zur besseren Zentrierung und zum zusätzlichen Abstützen der Wülste 7 des Quetschventilschlauches 6 werden die Innenflächen 12 durch das Eindrehen einer kreisring- und rratenförmigen Vertiefung in die Gehäuseflansche 3 und 5 gelegt; wie in Figur 2 dargestellt; und zwar so, daß die äußere Wand 13 der Vertiefung senkrecht zur Innenfläche 12 steht, und die innere Wand \k der Vertiefung in einem stumpfen Winkel zur Innenfläche 12 steht.For better centering and for additional support of the beads 7 of the pinch valve hose 6, the inner surfaces 12 are placed in the housing flanges 3 and 5 by turning a circular and rat-shaped recess; as shown in Figure 2; in such a way that the outer wall 13 of the recess is perpendicular to the inner surface 12, and the inner wall \ k of the recess is at an obtuse angle to the inner surface 12.
Die in den Wülsten 7 des Quetschventilschlauches 6 einvulkanisierten Metallringe 8 enthalten auf ihren äußeren konischen Oberflächen radial angeordnete, wellenförmige Rillen 10 zur Vergrößerung der Vulkanisierflächen.The vulcanized into the beads 7 of the pinch valve hose 6 Metal rings 8 contain, on their outer conical surfaces, radially arranged, wave-shaped Grooves 10 to enlarge the vulcanization areas.
In dem Quetschventilschlauch 6 befindliche Gewebeeinlagen 11 sind in den Wülsten 7 aus Festigkeitegründen um die Metallringe 8 ohne Unterbrechungen hervmgeführt.Fabric inlays located in the pinch valve hose 6 11 are around in the beads 7 for reasons of strength the metal rings 8 without interruptions.
Der Gehäusemantel 1 enthält in Längsrichtung mindestens vier sickenförmige Vertiefungen 2; wie in Schnitt a-a dargestellt.The housing jacket 1 contains at least four bead-shaped depressions 2 in the longitudinal direction; as in section a-a shown.
Diese Ausführung erzielt folgenden Fortschritt:This execution achieves the following progress:
a. Der Quetschventilschlauch erreicht durch seine nicht eingepreßten Enden eine erheblich höhere Standzeit.a. The pinch valve hose has a considerably longer service life thanks to its non-pressed ends.
b. Das Ein- und Ausbauen des Quetschventilschlauches ist gegenüber herkömmlichen Quetschventilen bei dieser Bauart wesentlich vereinfacht.b. The installation and removal of the pinch valve hose is compared to conventional pinch valves with this one Design significantly simplified.
c. Das neue Quetschventil besteht aus einem Minimum an Bauteilen.c. The new pinch valve consists of a minimum of components.
d. Dieses Quetschventil baut gewichtsmäßig erheblich leichter als herkömmliche Quetschventile.d. This pinch valve is considerably lighter in weight than conventional pinch valves.
