This disclosure relates to a shut-off valve, in particular a pipe-bridge slide valve, for a coking drum for the production of coke, having at least one pipe socket which has a first end for connection to the coking drum and a second end on which a slider is arranged for opening and closing the coking drum, wherein the pipe socket has a supply connection for filling the coking drum with a medium and a diaphragm which is arranged between the supply connection and the first end of the pipe socket and can be moved into a filling position and into an emptying position, wherein, in the filling position, a diaphragm opening is arranged in the region of the central longitudinal axis of the pipe socket for introducing the medium centrally into the coking drum, and, in the emptying position, the diaphragm opening has a larger passage area than in the filling position.

In embodiments, a gate valve includes a valve body including a flow passage from a first opening to a second opening, and a gate channel having a first end intersecting the flow passage and a second end delineated by a third opening. A valve cover fits over the third opening. A cap fits over a valve cover opening. In embodiments, a valve cover includes a body with a second sealing surface protruding from a first sealing surface, both around an opening of the body. A cap has a third sealing surface to mate with the first sealing surface, and a fourth sealing surface congruent to the second sealing surface. In embodiments, a valve cover cap includes a body with a first sealing surface on an end of a wall. Pin flanges each have a pin hole having a pin hole axis oriented perpendicular to a center axis of the wall.

A gate valve provided in a boundary portion between two sections to block communication between the two sections, the gate valve includes a base, a first moving mechanism installed on the base and configured to move a first movement body along a first linear track, a second moving mechanism installed on the first movement body, and configured to operate at a timing different from the first moving mechanism and to move a second movement body along a second linear track orthogonal to the first linear track, and a valve body installed on the second movement body and configured to come into contact with a contact surface so as to perform sealing. One of the first linear track and the second linear track is parallel to a direction orthogonal to the contact surface.

A connecting fitting is disposed on an upper face of a valve plate and is fixed to the connecting shaft. A first close-contact mechanism portion is formed at a portion where the connecting fitting and the connecting shaft are in contact with each other, a second close-contact mechanism portion is formed at a portion where the connecting fitting and the valve plate are in contact with each other, and a third close-contact mechanism portion is formed at a portion where the lower end of the valve plate and the lower end of the connecting shaft are in contact with each other. By bringing the valve plate and the connecting shaft toward each other with the close-contact mechanism portions of three vertical positions, a hole front face of a connection hole and a shaft front face of a connecting shaft are brought into close contact with each other.

A shut-off system of the present invention includes a straight pipe made of a polyolefin-based material, and a knife gate, wherein: a semicircular arc-shaped first cutting blade is formed on a distal end side of the knife gate to cut open the straight pipe to form a slit-shaped opening; an arc band-shaped sealing portion is formed on a proximal end side of the knife gate to be in contact with cut surfaces of the straight pipe; the knife gate includes a pair of side edge portions that connect the first cutting blade and the sealing portion; the first cutting blade and the side edge portions bite into an inner circumference surface of the straight pipe along the inner circumference surface; the knife gate is formed in a flat plate shape having a first surface and a second surface, extending from the first cutting blade to the sealing portion and between the pair of side edge portions; the opening extends in a circumferential direction on the straight pipe; and the sealing portion extends from one end of the opening to the other end thereof, and extends from the inner circumference surface to an outermost surface, which is on an outermost side, of the straight pipe.

Pipeline apparatus comprising a housing including a riser and a pipeline connector and a device configured to interact with fluid flowing through the pipeline connector, a mounting structure for releasably mounting the device in the riser and seal situated between an inner surface of the riser and an outer surface of the mounting structure, the seal configured to seal against egress of fluid from the apparatus, the mounting structure and the riser each including a part of a locking structure for releasably locking the device in the riser, the device situated in the pipeline connector.

A clamp assembly to secure a yoke to a valve body of a knife gate valve is provided. The clamp assembly can include a bolt that is configured to extend through a first bushing, a first spring member, a first side wall of the yoke, the valve body, a second side wall of the yoke, a second spring member, and a second bushing. The clamp assembly can be configured to pin the yoke to the valve body, apply a pressure-containing preload to the valve body via the first and second bushings, and compress the first spring member between the first bushing and the first side wall of the yoke and the second spring member between the second bushing and the second side wall of the yoke.

A connecting fitting is disposed on an upper face of a valve plate and is fixed to the connecting shaft. A first close-contact mechanism portion is formed at a portion where the connecting fitting and the connecting shaft are in contact with each other, a second close-contact mechanism portion is formed at a portion where the connecting fitting and the valve plate are in contact with each other, and a third close-contact mechanism portion is formed at a portion where the lower end of the valve plate and the lower end of the connecting shaft are in contact with each other. By bringing the valve plate and the connecting shaft toward each other with the close-contact mechanism portions of three vertical positions, a hole front face of a connection hole and a shaft front face of a connecting shaft are brought into close contact with each other.

The present invention is an elastic (mechanically stretchable), sanitizing pouch configured to receive and hold an Electronic Device of a predetermined configuration. The elasticity of the fabric used maximizes surface contact with the Electronic Device and the closeness of the fabric of the invention with the outside surfaces of the Electronic Device. A liftable and removable cover flap on the front of the invention is used to hold and access the inside of the invention. The back of the invention includes at least one pocket. The invention further includes a pull tab to help lift an Electronic Device out of the invention. While inside the invention, the silver ions are released in the fabric and inhibit the colonization of bacteria, viruses and fungus on the Electronic Device.

A metering device for bulk material has a metering container with an outlet opening provided with a rim. A slide is connected to a slide drive and closes the outlet opening. The slide is provided with a slide rim. The rim of the outlet opening and the slide rim, as a function of a displacement travel of the slide in a displacement direction, determine a travel-dependent outlet cross section of the outlet opening. The rim of the outlet opening; or the slide rim; or the rim of the outlet opening and the slide rim extend at a slant to the displacement direction of the slide.
