摘要： A slide valve comprises a valve housing which has a through passage therein with a curved bottom and a recess along the bottom in which is located a resilient seal member. The valve member includes a slide portion which is mounted for upward and downward reciprocal movement in the housing and a guideway formed on each side of the curved bottom. The housing also contains a flange member on each side of the slide plate which has at least one notched portion which defines a scraper edge. The valve plate has a lower stepped portion forming a bottom projecting surface, an upper surface spaced away from the bottom edge and an intermediate ledge surface between the bottom and upper surfaces. The upper surface is curved downwardly at each side toward the bottom surface to define a shearing edge on each side of the slide plate which is cooperable with the scraper edge to dislodge material out of the guideway and the space between the flanges and into the flow stream of the through passage of the valve.

摘要： A sliding plate of a gate valve is guided in guide grooves formed in the region of a flow passage of the two-part gate valve housing. Each guide groove is bounded on both sides [upstream and downstream] by guide strips which extend into the flow channel. The guide strips have axially outwardly directed chamfers, and each such strip has a circular arcuate shaped recess. The recess, which starts at the upper entry point of the guide groove into the flow channel, extends to the lower third of the guide strip. The maximum depth of the recess is 3-5 mm less than the depth (t) of the guide groove 4b. The guide grooves 8a, 8b provide problem-free guiding of the sliding plate when said plate is moved to its closed position, particularly when said plate is moving through the lower third of the flow channel; nonetheless, the guide grooves 8a and 8b present only minimal flow resistance. When the sliding plate is being closed, material which may have deposited in the relatively short parts of the grooves which parts are not affected by the recess, can be expelled without problems via the closing-edge of the sliding plate.
摘要翻译： 闸阀的滑板在形成在两部分闸阀壳体的流动通道区域中的引导槽中引导。 每个引导槽通过延伸到流动通道中的导向条限定在上游和下游两侧。 导向条具有轴向向外指向的倒角，并且每个这样的条具有圆弧形凹部。 从引导槽的上入口开始进入流动通道的凹部延伸到导向条的下三分之一处。 凹槽的最大深度比引导槽4b的深度（t）小3-5mm。 当所述板移动到其关闭位置时，特别是当所述板移动通过流动通道的下三分之一时，引导槽8a，8b提供滑板的无故障导向。 然而，引导槽8a和8b仅具有最小的流动阻力。 当滑板被关闭时，可能已经沉积在槽的相对短的部分中的不受凹部影响的部分的材料可以通过滑板的闭合边缘而无问题地排出。

摘要： A guide slot for a valve plate is bounded on both sides by guide strips projecting into a flow channel of a valve housing for the plate. These guide strips contain notches at intervals. The notches of one guide strip are offset relative to the notches of the other guide strip. When the valve is open, medium entering the guide slot through the notches on the inflow side is deflected in the guide slot before it leaves the guide slot again through the offset notches on the outflow side. This generates in the guide slot a lengthwise current leading to a self-cleaning action for combatting deposits. During the valve plate closing process, a permanent self-cleaning takes place over the entire closing travel zone. For this reason, the valve is particularly well suited for use in conveyor lines for thickish, powdery, granular or solids-containing media.
摘要翻译： 用于阀板的导槽在两侧通过突出到用于板的阀壳体的流动通道中的引导条限定。 这些导板间隔有凹口。 一个引导条的凹口相对于另一个导带的凹口偏移。 当阀打开时，通过流入侧的凹口进入引导槽的介质在引导槽再次通过流出侧的偏移凹口离开引导槽之前被偏转。 这在导槽中产生纵向电流，导致用于抵抗沉积物的自清洁动作。 在阀板关闭过程中，在整个关闭行程区域进行永久性自清洁。 因此，该阀特别适用于用于厚粉末，粉末状，颗粒状或含固体的介质的输送线。

摘要： The slanted closing rim of a valve plate includes a cylindrical portion at the rear side, having a diameter D1 which corresponds to the width of the plate and slightly exceeds the diameter D3 of the passage throat. A groove in the casing guides the narrow sides of the valve plate and accomodates a seal strip. The grooves partly closed at the front side by a guide strip which in the bottom zone of the passage throat is a semicircularly extending strip. The inside diameter D4 of this cylindrical strip approximately corresponds to that of the valve plate and its axis a extends at a level which is higher by half the difference between diameters D1 and D3 than that of the axis b of the throat passage. A slanted closing rim of the valve plate is provided with shear arcs on its frontal points on each of the side edges. The two shear arcs form a kind of a plowshare deflecting the medium from the seal.

摘要： A shutoff device comprises a housing having a closable flow passage which is closed by a closing plate member which moves into a recess defined in said housing forming a receiving seat. The closing plate member is closed by the movement of a fluid pressure operated piston which moves the closing plate member rapidly into the closed position. In order to prevent the closing plate member from slamming into the valve seat and damaging the valve seat, there is provided a bolster member in the form of a stop which is disposed in the path of movement of a stop face connected to a piston rod of the fluid pressure's piston which is connected to the closing member. The bolster member is made of a material which is non-elastic but which deforms after it is contacted by the stop face to initially stop the closing plate member and is then deformed to permit final closing of movement of the closing plate member into a completely closed position engaged in the recess seat and also to absorb the closing force by its own deformation.
