摘要:
The invention relates to a method for machining a sealing seat (24a, b), arranged at the end (26) of a connection pipe (8a, b), of a shut-off valve (6) fitted in a power generating or industrial plant (2), which method comprises the following steps: a) an upper valve part (16) and the internal housing fittings (32) are removed from the housing (10) of the shut-off valve (6), whereby a housing opening (14) is exposed, b) a clamping device (40), having a counter-bearing (56), is introduced through the housing opening (14) into the or a further connection pipe (8a, b) and fastened to the inner wall (50) thereof, c) a machine tool (58), having a bearing (64), is introduced into the housing (10) through the housing opening (14) and mounted with its bearing (64) on the counter-bearing (56), d) a machining step (B1-4) is carried out with the machine tool (58) on the sealing seat (24a, b), e) the machine tool (58) is detached from the counter-bearing (56) and removed through the housing opening (14), f) if need be, steps c) to e) are repeated with another or the same machine tool (58), g) the clamping device (40) is detached from the connection pipe (8a, b) and removed through the housing opening (14), and h) the upper valve part (16) and the internal fittings (32) are attached to the housing (10). A device for machining a sealing seat (24a, b), arranged at the end (26) of a connection pipe (8a, b), of a shut-off valve (6) fitted in a power-generating or industrial plant (2) comprises a clamping device (40), which can be introduced through a housing opening (14) of the shut-off valve (6) into the or a further connection pipe (8a, b) and includes a counter-bearing (56) and a fastening element (47) interacting with the inner wall (50) of the connection pipe (8a, b), and at least one machine tool (58), which can be introduced through the housing opening (14) into the housing, for carrying out a machining step (B1-4) on the sealing seat (24a, b), wherein the machine tool (58) has a bearing (64), which can be mounted in the counter-bearing (56).
摘要:
A valve in which an elastic member (26) containing a normally closed slit (28) is adapted to be selectively stretched by displacement of an actuating means, such as to stretch open the slit (28) over the outlet end (27) of a product discharge passage defined by a tube (24) and allow fluid product to be dispensed therefrom, release of the actuating means allowing the elastic member, and hence the distorted slit (28) to return to its original configuration, thereby reclosing the outlet end of the passage. The actuating means comprises a pair of relatively pivotable actuating members (30a, 30b) relative angular displacement of which is adapted to stretch open the slit (28) in the elastic member (26) over said outlet end (27) of the product discharge passage defined by the rigid tube (24).

A Self Priming Gravity Wave Water Pump, Double Acting, vertically Self Adjusting incorporating a Submerged Column Platform as shown in Figure 4A, the submerged column platform (22) can be tethered (28) or secured by a pivot to a weight (29) or fixed into the water bed (31). The column (22) can be incorporated into an additional submerged water filled column chamber (23), to operate as a hydraulic tidal adjustable column platform. The Gravity Wave Pump (9) is a wave energy converter using wave energy in the form of wave motion to displace a float (2), to lift the pumps reciprocating piston (12) and uses gravity, causing a weight (3) to push a piston down as the wave passes. The pump could pressurise piped water to a head of up to 100 metres or more and could pump pressures in excess of 150 pounds per square inch when adjusted accordingly.

The invention relates to a vehicle for transport of material. To allow for the pellet-like material, such as cattle feed, to be unloaded without disturbance, the height adjustable closing member (19) of the discharge funnel (8) is provided with a cutting edge (33) for destruction of pellet-like material.
