Abstract
Abstract Slide valve for use as a bypass slide valve for medium supplying pipes with a relatively large pressure compri-sing a housing (11) with a pipe socket (15, 16) each at the inlet side and at the outlet side and a sliding plate (12) movable with a lifting rod (14) squarely to the middle axis M of the pipe sockets wherein the inside jacket of the pipe socket (15) at the inlet side is conically tapered towards the sliding plate (12) wherein the slide valve comprises a device (17, 17', 18, 18', 19, 19') for lifting the sliding plate (12, 13) in paral-lel with the middle axis M to move the sliding plate without wear.

Claims (12)
1. Slide valve for use as a bypass slide valve for medium supplying pipes with a relatively large pressure comprising a housing (11) with a pipe socket side and a sliding plate (12) movable with a lifting rod (14) squarely to the middle axis M of the pipe sockets, c h a r a c t e r i z e d i n, that the inside jacket of the pipe socket (15) at the inlet side is conically tapered towards the sliding plate (12).
2. Slide valve according to claim 1, characterized in that the inside jacket of the pipe socket (15) is inclined in relation to the middle axis M in an angle of about 2° to 4°.
3. Slide valve according to claim 1 or 2, characterized in that the largest inner diameter D of the pipe socket (15) at the inlet side is about equal to the inner diameter DA of the pipe socket (16) at the outlet side.
4. Slide valve according to one of the preceding claims, characterized in that the end of the pipe socket (16) facing the sliding plate (12) comprises a first annular seal (21) at the outlet side, and that a second approximately annular seal (22) is arranged at the sliding plate (12), the second seal (22) sealingly cooperating with the first annular seal in the closed position of the sliding plate (12).
5. Slide valve according to claim 4, characterized in that the seals (21, 22) are made of metallic materi-al
6. Slide valve according to claim 5, characterized in that the metallic material is stainless steel.
7. Slide valve according to claim 4, characterized in that the first annular seal (21) consists of metal-lic material and that the second annular seal (22) consists of an elastic non-metallic material.
8. Slide valve according to claim 7, characterized in that the elastic, non-metallic material is silicone rubber.
9. Slide valve according to one of the preceding claims, characterized in that the sliding plate (12) comprises an approximately circular opening (13) with the diameter thereof about equal to the smallest inner diameter D' of the pipe socket (15) at the inlet side.
10. Slide valve according to one of the preceding claims, characterized by a device to move the sliding plate (12) in parallel with the middle axis M of the pipe socket.
11. Slide valve according to claim 10, characterized in that the device comprises skid rails (17, 17') arranged in parallel with the lifting rod (14) with the skid rails slidingly encompassing the lateral edges of the sliding plate (12), and that the skid rails (17, 17') are movable in parallel with the middle axis M by lifting devices (18, 18', 19, 19') arranged at the housing (11).
12. Slide valve according to claim 10 or 11, characte-rized in that the lifting devices (18, 18', 19, 19') comprise at least two fluid operated lifting motors for each skid rail (17, 17') with the piston rods of the lifting motors connected with the skid rail (17, 17') and with the cylinders of the lifting motors connected with the housing.
