摘要： A service tee (T) of this disclosure includes a valve plug (V) having a plunger (31) connected to a threaded stem (27) extending from a bottom end (10b) of a plug body (10). Turning the threaded stem actuates the plunger, thereby advancing and retracting a seal (35) of the plunger to block or allow flow respectively. An anti-rotation stop (23) prevents the plunger from rotating as the threaded stem linearly displaces the plunger. A keyway or drive (10d) for actuating the plunger remains recessed in the body of the plug so that prior art plug insertion tools can be used for plug installation. In some embodiments, the plug insertion tool may be a hot tapping machine. Once the plug has been set into a pressurized pipeline fitting, every leak path is sealed using non-metallic (e.g. elastomeric or polymer) sealing technology.

摘要： A valve comprises a body that includes a first channel connected to the gas tank and a second channel connected to a circuit, with the first and second channels communicating with a central housing. The valve comprises a closure member movable between a closed position of the first channel and a supply position in which the first and second channels communicate. A third channel is formed in the body and communicates with the central housing The closure member is configured to isolate the third channel from the first and second channels in the closure and supply positions, and to allow communication between the third channel and the first and second channels in a discharge position.

摘要： A plug valve assembly includes a valve carried in a valve body and including a spindle coupled to a plug. The spindle may have an appendage coupled to a sidewall of the plug, and circumferentially extending about a rotational axis less than 180 angular degrees, such that the spindle appendage is registrable with a valve body outlet to selectively reinforce the plug sidewall and thereby resist blowout of the plug sidewall into or through the valve body outlet. The spindle may be composed of nylon and the plug may be composed of liquid silicone rubber.

摘要： A valve arrangement according to the present disclosure includes a valve module and a drain valve. The valve module includes first and second functional spaces, and an attachment interface defining a passage into one of the first or second functional spaces. The drain valve includes a fluid inlet and a fluid outlet formed through a common connector part that is connectable to the attachment interface to connect the fluid inlet of the drain valve to the second functional space and the at least one fluid outlet to the first functional space.

摘要： Irrigation valves for channels and for irrigation tanks are of three types. All are activated by a pair of tilting float arms to which a pair of floats are attached. One type is a T-shaped duct with a cylindrical valve disposed at 90 degrees to the part that is connected to the incoming flow. The floats rotate the valve. The second type has the same construction as the first type, thereby giving flow control but additionally has a rise and fall gate in the duct part that is connected to the incoming flow. The gate acts as a stop valve. The third type has a cylindrical duct connectable to the incoming flow but no valve and provides both flow control and stop valve facilities through a rise and fall gate actuated by the tilting of the float arms.

摘要： This invention, through an arrangement of basic elements, has resulted in a new device for landscape irrigation which has not been previously available. This implementation is an electromechanical device which can potentially revolutionalize the entire landscape irrigation industry. During operation it cyclically varies the amount of water ejected from a sprinkler device and thereby provides a more uniform coverage than is ordinarily available. This obviates the necessity to have additional sprinklers fill in the under-watered areas. The device accomplishes this by utilizing a synchronous alternating current motor to drive a rotor which, as it rotates, varies the flow rate of the water to the sprinklers. The motor is powered by the same source that powers the valves feeding water to the sprinklers. Its use will drastically reduce the amount of irrigation water required, helping to save a precious resource.

摘要： A valve has a body having a rotatable valve element. A drive mechanism has a drive input member and a drive output member that are coupled to the valve element for rotating the valve element. A shear member is operatively located within the drive mechanism between the drive input member and the drive output member for shearing in the event the force to rotate the valve element is excessive. The valve has indicia indicating open and closed positions for the valve element. An indicator is mounted to output drive member to properly align with the indicia regardless whether the shear member has sheared or not.
