摘要： Various implementations of a firefighting valve assembly are disclosed. The firefighting valve assembly is especially suitable for fighting wildland fires. In some implementation, the firefighting valve assembly has a spatial profile that makes it easy to pack with long bundles of firefighting hose and easy to connect segments of firefighting hose as part of a hose lay. In some implementations, the firefighting valve assembly has a spatial profile that prevents it from inadvertently opening or closing when the hose is moved or pulled along the ground.

摘要： An irrigation sprinkler can be provided with a flow guard feature configured to send an indicator stream into the air when a nozzle is missing, while still conserving most of the water that would have been wasted without the flow guard feature. The flow guard feature can include a valve assembly having a first port and a second off-axis port. The second port can be smaller than the first port. The second port can be non-parallel to the first port. The first port can be open when the nozzle is present and be sealed when the nozzle is missing. The second, off-axis port can be open even when the nozzle is missing to provide the indicator stream.

摘要： A shower head water-saving switching structure and a shower head are disclosed. The shower head water-saving switching structure includes a water inlet seat, a water discharging body, a functional water switching member, a flow switching member, and a drive mechanism. The water inlet seat and the water discharging body are connected to form a water distribution chamber therebetween. The drive mechanism includes a ratchet wheel, a push rod in linked with the ratchet wheel, and a button linked with the push rod. The functional water switching member and the flow switching member are rotatably accommodated in the water distribution chamber and linked with the ratchet wheel. The structure is simple, and the operation is effortless.

摘要： A valve for metering a fluid, including an electromagnetic actuator and a valve needle which is actuatable by an armature of the actuator and used to actuate a valve closing body which cooperates with a valve seat surface to form a seal seat. The armature is movably guided at the valve needle in the process. A stop element connected to the valve needle limits a relative movement between the armature and the valve needle in connection with an actuation of the valve needle. At least one elastically deformable spacer element is provided between the armature and the stop element, which, during the limitation of the relative movement between the armature and the valve needle at the stop element, encloses an attenuation space provided between a front face of the armature and a stop element surface of the stop element facing the front face of the armature.

摘要： A flexible dispensing apparatus for coupling to pressurized fluid containers is described. It includes a flexible tube and a handle assembly. The handle assembly houses a second end of the tube. The handle assembly has a first side connected to a second side, a slide trigger, a roller coupled to the bottom of the slide trigger with a dowel pin, a spray nozzle assembly, a magnet reservoir, and a magnet. The first side has an inclined ramp that runs along a length of the first side and extends into the second side above and beyond a seam that is formed by the connection of the two sides. The tube is within a channel in the handle assembly formed between the inclined ramp and the roller. When the roller is rolled toward the end of the ramp it pinches the flexible tube near the top of the inclined ramp.

摘要： An adjustable spray nozzle with adjustable arc of coverage as well as spray elevation angle and flow rate. A very simple adjustable arc of coverage spray nozzle configuration is also disclosed which may be easily assembled for a particular precipitation rate and/or range of coverage at a selected nominal pressure. Also disclosed is a simple fixed arc of coverage spray nozzle with selectable ranges for a particular precipitation rate.

摘要： A mixing valve assembly includes a valve housing defining an interior, a cold inlet along a first axis, a hot inlet, and a mixed outlet. A metering ball within the interior rotates about the first axis. The metering ball has an outer shell defining: a cold port aligned with the cold inlet; a hot port selectively aligned with the hot inlet; a cold outlet connected to the cold port; and a hot outlet connected to the hot port. Rotation of the metering ball aligns the hot port with the hot inlet, the cold outlet with the mixed outlet, and the hot outlet with the mixed outlet to varying degrees. The metering ball has a central flowpath for hot water and a radially outward flowpath for cold water.

摘要： A nozzle device includes a first passage, a second passage, and a first ambient valve clapper. The first passage includes a first intake and a first outlet. The second passage includes a second intake and a second outlet. The first ambient valve clapper is configured to control entry of fluid into the second passage through the second intake. The fluid is pumped to enter the first passage through the first intake to form a first negative pressure zone next to the first outlet, and the first ambient valve clapper is opened via a pressure difference between the first negative pressure zone and the surrounding of the nozzle device, allowing the fluid to flow into the second passage.
