A hydrant includes: a hydrant body defining a hydrant inner cavity, the hydrant configured to couple to and be in fluid communication with a fluid distribution system including a fluid therein under pressure; and a break check valve coupled to the hydrant body, the valve including: a valve body defining a valve inner cavity, the hydrant inner cavity defining a valve bore in fluid communication with the fluid during normal operation of the hydrant; a valve member configured to rotate from an open position to a closed position of the valve; and an arm in contact with the hydrant and configured to prevent movement of the valve member when the hydrant is coupled to the valve, the valve defining a hole separate from the valve bore and in fluid communication with each of the hydrant inner cavity and the valve inner cavity.

Intended is to improve the corrosion resistance of an overlay used in a nuclear power plant, and to reduce dissolution of cobalt from an overlay. The corrosion and wear resistant overlay 7 is formed along a surface of a base 2 by laser lamination modeling, and is configured from a plurality of metal layers 1a, 1b, 1c, and 1d of a Co-base alloy. The thickness of carbide eutectics that precipitate in the metal layers 1a, 1b, 1c, and 1d is the largest in the metal layer 1a closest to the base 2, and is gradually smaller in the metal layers 1b, 1c, and 1d farther away from the base 2. The intensity of the laser beam applied to form layers by laser lamination modeling is adjusted so that the carbide eutectics that precipitate in at least the outermost metal layer 1d have a controlled size of 10 μm or less.

A sealing assembly for controlling a flow of fluid through a fluid line has a housing having a first end opposite a second end with a hollow interior extending therebetween and an elastically resilient plug disposed within the hollow interior of the housing. The plug has a body engagable with a seat within the housing and a tension member having a first end connected to the body and a second end connected to the housing. The tension member is pre-loaded in tension to urge the body of the plug against the seat to seal the hollow interior of the housing. The body is movable away from the seat when the plug is acted upon by a fluid pressure greater than a pre-load force of the tension member.

Apparatuses of the present invention create a backward pressure in fluid traversing a pipe, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid, allowing more accurate water meter measurements. The apparatus comprises a poppet valve having multiple springs to minimize or eliminate spring-binding caused by off-center hydraulic force during use.

A fully-draining check valve with a mushroom assembly having a tapered back edge and a drain line disposed with the lower rim of the drain line below the tapered back edge to ensure no fluid becomes trapped in the check valve when not in use. Additionally, a fully-draining diaphragm pump is disclosed having a drain line configured to drain the lowest point of a product chamber to ensure no fluid becomes trapped in the diaphragm pump when not in use. A method of cleaning a fully-draining diaphragm pump and fully-draining check valve assembly is further disclosed comprising inducing turbulent flow of water, wash solution, and/or sanitizer through the assembly and opening ball valves the drain lines of the fully-draining check valves to vent the assembly.

A storage container having a base storage compartment configured to receive a divider by which the storage compartment is divided into two or more sub-compartments, wherein divider includes a tool configured to provide a secondary utility or function unrelated to dividing the storage compartment.

A valve system (13), connectable to a pump system (1), includes a pump assembly (3) connectable to a pipe (5), wherein the valve system (13) includes a valve (15) including a pipe section (39), of the pipe (5), that defines a primary flow direction (19), and a valve opening (41) in the pipe section, a valve seat (43) and a valve body (45). The valve opening (41), the valve seat (43) and the valve body (45) define a common valve axis (47) extending transversely to the primary flow direction. An operating element (49), arranged at the pipe section opposite the valve opening, is configured to control the valve body for operating in a check-valve mode to open the valve opening upon a fluid flow from the valve opening towards the valve body and for operating in a shut off-valve to close the valve opening for any fluid flow direction.

A wiper arm adapter device with at least one fluid channel (44a, 46a; 44b, 46b) for conducting a fluid, and with at least one connecting unit (48a; 48b) for connecting the fluid channel (44a, 46a; 44b, 46b) to a fluid line element (36a; 36b) of a wiper arm and/or to a wiper blade adapter (30a; 30b), wherein the connecting unit (48a; 48b) has at least one connecting element (52a, 54a; 52b, 54b) which at least partially delimits the fluid channel (44a, 46a; 44b, 46b). The connecting unit (48a; 48b) has at least one valve element (56a, 58a; 56b, 58b) which is arranged on the connecting element (52a, 54a; 52b, 54b) and is configured to form the fluidic connection of the fluid channel (44a, 46a; 44b, 46b) to the wiper blade adapter (30a; 30b) in a closeable manner.

A linear compressor includes a cylinder, a discharge valve, a valve spring pressing the discharge valve to close one side of the cylinder, and a spring support portion providing a support point for the valve spring to press the discharge valve. The valve spring includes a first spring arm whose center is connected to the discharge valve and extending spirally, a second spring arm spaced apart from the first spring arm by a predetermined distance with respect to an axial direction of the cylinder and extending spirally toward an outer portion according to a shape of the first spring arm, and a rubber damper connecting the first spring arm and the second spring arm and fixing relative positions of the first spring arm and the second spring arm.
