摘要： Exemplary embodiments are directed to butterfly valves, generally including a body assembly and handle assembly. The body assembly generally includes a body, a disc rotationally disposed inside an opening of the body, a cog, and a stem passing through the disc and the body. The handle assembly generally includes a handle body and a force ring. The stem can be rotationally interlocked relative to the disc and the handle assembly. The cog and the force ring can engage to rotationally secure the disc relative to the body. The handle assembly can include a lever and a grip, the force ring, the lever and the grip being pivotally secured relative to each other. The body can include a male radial protrusion and the body assembly can include a liner with a female radial groove. Methods of assembling and positioning a butterfly valve are also provided.

摘要： A gate valve for controlling flow of a fluid therethrough is provided. The gate valve includes a valve body having an outer surface, a bore, a valve cavity, a first seat pocket, a second seat pocket, and first and second fluid ports extending from the outer surface to the first and second seat pockets, respectively. First and second seats are positioned respectively within the first and second seat pockets. The seats include circumferential fluid channels and one or more conduits in fluid communication with the fluid ports for permitting a repair fluid to be injected into the ports to the faces of the seats. A gate is slidably positioned within the valve cavity between the first seat and the second seat for controlling flow of a fluid through the valve. Sand shields are also provided at the rear of the seats to capture particulates and to bias the seats against the gate.

摘要： A backflow preventer adapted for installation in an inner conduit of a hose coupling of a hydrant is disclosed. The backflow preventer contains a non-return device having a closing body, a seal seat, and a resetting device. The resetting device is adapted to resiliently pretension the closing body into sealing engagement against the seal seat.

摘要： A valve for variable throttling of a hydraulic flow includes a tappet and a guide element in which the tappet is guided for movement in a stroke direction. The valve also includes at least one fatigue-resistant, mechanical member that locally reduces a radial play of the tappet so as to reduce possible valve oscillations.

摘要： The present invention relates to an air admittance valve (AAV) that operates automatically at low pressures to selectively open and close an air passageway between an inlet and an outlet. The AAV comprises a valve body having a centrally disposed, internal valve chamber in communication with the ambient environment, and having a valve seat. The AAV includes a sealing member having a flexible diaphragm that is fastened to a support ring, the ring defining one or more lugs on an outer periphery thereof. The AAV further includes a cap member within which the sealing member may be disposed, such that the one or more lugs may interact with an interior surface of the cap. The sealing member may selectively seal or unseal from the valve seat in response to pressure differentials between the inlet and the outlet.

摘要： An overmolded valve is provided for use in a container having a throat. The valve is inserted into the throat of the container and prevents liquid from flowing from the container during shipment or storage. When the container is inverted for use with a dosing and/or dispensing apparatus, the valve remains closed until it is opened by an upward force to permit liquid to flow from the container, by gravity, to the dosing and/or dispensing apparatus. The valve closes when the upward force is removed. A pair of plastic semi-helical springs urge the valve to the closed position.

摘要： A valve assembly for a fluid pump includes a valve body; an inlet disk movably disposed in the valve body; an outlet disk movably disposed in the valve body; and a valve seat fixed within the valve body. The valve seat includes a first aperture defined axially through the valve seat in a radial central portion thereof, and one or more second apertures disposed at least partly around the first aperture. The inlet disk is biased in a closed position against the valve seat along a first surface thereof, the closed position of the inlet disk covering the one or more second apertures of the valve seat. The outlet disk is biased in a closed position against the valve seat along a second surface thereof.

摘要： A vent valve flow fuse includes a valve cap with a valve cap cavity defined by one or more valve cap interior surfaces. The vent valve flow fuse includes a valve body with a valve body cavity defined by one or more valve body interior surfaces. The vent valve flow fuse includes a poppet configured to at least partially fit within the valve cap cavity and the valve body cavity. The vent valve flow fuse includes a spring configured to fit within the valve body cavity and to generate a resistive force against the poppet. The poppet is in a first position when fluid having a first amount of fluid pressure enters the valve cap cavity from a vent valve and engages the poppet. The poppet is in a second position when fluid having a second amount of fluid pressure enters the valve cap cavity and engages the poppet.

摘要： A linear compressor includes a spring axially elastically supporting a driving assembly. The spring includes a spring body axially extending, a front spring link forming an end of the spring body by extending from a side of the spring body, and a rear spring link forming the other end of the spring body by extending from the other side of the spring body. Any one of the front spring link and the rear spring link is fixed to the driving assembly and the other one is fixed to a supporting assembly.
