Abstract

763,851. Slide valves. WEY, J. April 14, 1954 [April 18, 1953], No. 11068/54. Class 135. A gate valve has a closed sealing element which completely surrounds the valve passage, the element being constituted by a U-shaped first sealing portion 9 of elastic material such as rubber arranged in the plane of the valve plate or gate 2 so that when the valve is closed the closing edge 3 of the gate is substantially flush with the wall of the valve passage 6 and a second sealing portion 11 also of elastic material arranged in a groove 10 in the inner wall of the valve body and constantly engaging the valve plate. The ends of the portion 9 meet the portion 11. In the screw-actuated valve shown in Fig. 2, the sealing portion 9 is held in a groove 8 formed in two body parts joined by screws 7. Where the valve is normally closed and its outlet side is at a low pressure the portion 11 is not constituted as a ring as in Fig. 2, but extends across the high-pressure side only of the valve plate and is made in one piece with the U-shaped sealing portion 9. The body parts 1 may extend only to the sealing portion 11 and may be surmounted by an upper body part having a groove to receive a further sealing ring embracing and sealing against the valve gate. Fig. 9 shows a further arrangement having inner body parts 20 which may be of high grade corrosion-resisting material and outer body parts 19, all the parts being held together by screws 24. The valve gate or plate 2 which is operated by an off-set non-rising spindle 21 supporting a nut 22 is engaged by a sealing ring 26 and engages in the close position a U-shaped sealing portion 25 similar to the portion 9. The ring 26 may be arranged in a groove the lowest point of which is over the axis of the valve passage. Guides 27 for the plate 2 project inwardly from the wall of the valve passage and scrapers 28 are arranged in grooves within the sealed area of the valve body and pressed against the valve plate by a resilient ring 29. In a further modification two additional seals in the form of overlying frames are provided between the body parts 1.
