摘要： Gas admission valve assembly includes a housing, an elongated valve guide disposed within a central bore of the housing, a valve including a valve stem slidably disposed within the valve guide and a valve head selectively engagable with a valve seat of the housing to control flow between gas entry and exit openings into a housing entry chamber. First and second stem seals are disposed at opposite ends of the valve guide in sealing engagement with the valve stem between the valve stem and the central bore of the housing distally and the valve guide proximally.

摘要： A bearing greasing assembly for simultaneously greasing a plurality of bearings includes an agricultural implement which includes a frame and a plurality of rotating tilling. Each of the plurality of rotating tilling elements includes a bearing which has a grease input. A supply grease conduit is attached to the frame of the agricultural implement and the supply grease conduit has a zerk. A grease gun can be fluidly attached to the zerk to pump grease into the supply grease conduit through the zerk. The supply grease conduit branches into a plurality of outputs which is each in fluid communication with a respective one of the plurality of bearings. In this way each of the plurality of bearings can receive grease from the zerk.

摘要： A holding member configured to hold an injection portion and an imaging unit of an insertion portion in a state in which the injection portion and the imaging unit are arranged side by side includes an injection-portion insertion portion configured such that the injection portion is press-fitted into the injection-portion insertion portion and an imaging-unit insertion portion configured such that the imaging unit is press-fitted into the imaging-unit insertion portion. The insertion portion is configured to be inserted toward a corresponding portion in a narrow space while being gripped by an operator. The injection portion has a cylindrical shape and is provided with a fluid substance injection port at a tip end portion. The imaging unit has a cylindrical shape and is configured to capture an image including the tip end portion of the injection portion and its surrounding environment.

摘要： Methods and apparatus according to which a first valve is opened, or kept open, the first valve being part of a wellhead including a flow component above the first valve. The method may further include detecting a state of the first valve and, in response to detecting the state of the first valve, metering an amount of grease to the first valve. In addition, or instead, the method may further include opening, or keeping open, a second valve, the second valve being operably coupled to the wellhead and positioned above the flow component, and, after opening, or keeping open, each of the first and second valves, detecting whether the second valve is open or closed, in response to detecting that the second valve is open, preventing the first valve from being closed, and in response to detecting that the second valve is closed, allowing the first valve to be closed.

摘要： A greasing system may be placed partially within the red zone and partially outside of the red zone. Grease and pneumatic power is supplied from outside of the red zone to a pod, inside of the red zone, having local storage, high-pressure pumping capacity, and a distribution mechanism. The grease is supplied from outside of the red zone to the pod at low-pressure through a hose having at least a 1 inch inside diameter and is usually at least 100 feet long. The pod pressurizes the grease to a high-pressure and distributes the grease via a distribution mechanism to a relatively short hose, generally less than 8 feet between the distribution mechanism and the greasing point on the wellhead, in order to minimize pressure losses.

摘要： Grease distribution systems for lubricating a plurality of fracking valves on a wellhead include a distribution manifold configured for mounting on or adjacent to the wellhead, stand mount, mobile skid, grease skid or trailer. The distribution manifold includes a plurality of manifold valves configured for coupling in fluid communication with the fracking valves, respectively, on the wellhead. A grease pump is disposed in fluid communication with the distribution manifold. Methods of lubricating fracking valves on a wellhead are also disclosed.
