摘要： A two-stage filtering system including a first and second filter container. The first filter container has a first filter assembly with a foam filter sleeve enveloping a fluid intake device, a connected valve, and transfer tubing. The second filter includes a pump connected to a spout, a second stage splashguard strainer, a second stage cup filter, and a second filter assembly. The second filter assembly includes at least one main filter comprising at least one carbon body filter enveloping a filter chamber, and exit tubing. The first filter container is structured to stack on top of the second filter container and the transfer tubing is structured to transfer first stage filtered fluid to the second filter container. The pump is structured to draw second stage filtered fluid from the second container through the exit tubing and expel the second stage filtered fluid out the spout to provide purified water.

摘要： A straining device for bathtub drains to capture fallen hairs from water flowing into the drain. The straining device includes a tubular body that has multiple apertures in its wall and an open bottom. The body is divided into two parts that are pivotally coupled at the base through two opposite hinge joints. The tops of the two parts can be pivoted away from each other. To remove the trapped hairs, the tops of the two parts can be pulled away from each other resulting in dropping off the trapped hair on the outer surface of the straining device.

摘要： A water cleaner, including a housing and a filter mechanism. Two ends of the housing are provided with a first inlet and a first outlet, respectively. The filter mechanism is arranged in the housing. A first end and/or an outer circumstance of the filter mechanism are/is provided with a second inlet, and a second end is provided with a second outlet. The sewage flows into the housing through the first inlet and flows towards the filter mechanism to be filtered. The obtained clean water flows into the filter mechanism through the second inlet and flows out of the housing through the second outlet and the first outlet in sequence. The first end of the filter mechanism is close to the first inlet, and the second end is close to the first outlet.

摘要： A gutter protection assembly includes a frame, stanchions, and a mesh. The frame includes a rear brace and a supporting flange. The supporting flange is detachably attached to a front lip of a gutter using fasteners. The frame is defined by a series of alternating parallel ridges and a series of parallel channels such that each of the parallel channels define equally spaced openings. Each of the two self-supported stanchions include a base portion, an elongate stem portion inclined relative to the base portion, and two jaw portions extending from an end of the elongate stem portion that include a support clip for receiving adjacent portions of parallel ridges of the frame to define a space between a rear lip of the gutter and the rear brace of the frame. A mesh covers the frame to filter debris through the gutter.

摘要： A fluid flow control device includes a valve body defining an inlet, an outlet, and a fluid flow path extending therebetween, a valve seat ring coupled to the body that defines an orifice through which the fluid flow path passes, a cage coupled to the body that defines an interior bore, a control element slidably disposed within the interior bore of the cage, and a particle catcher at least partially disposed within an interior bore of the control element. The particle catcher includes a particle catcher body that defines an inner flow path and at least one particle catcher passage through which the fluid flow path passes. An outer surface of the particle catcher and an inner surface of the control element form a particle catching portion. The at least one particle catcher passage directs the fluid flow path downwardly into the particle catching portion.

摘要： A method of filtering a fluid for injection into an injection well comprises opening an actuator valve, actuating a pump in fluid communication with the actuator valve, receiving a fluid comprising solids within a filter assembly, where the pump is in fluid communication with the filter assembly, separating at least a portion of the suspended solids in the fluid within the filter assembly, ceasing separation of the suspended solids from the fluid, initiating a cleaning cycle for the filter assembly after ceasing separation of the suspended solids, washing at least the portion of the suspended solids from the filter assembly into a solids collection vessel using a cleaning fluid after initiating the cleaning cycle, and resuming separation of the suspended solids from the fluid after washing at least the portion of the suspended solids from the filter assembly.

摘要： Described are cleaning devices intended for immersion in water of swimming pools and spas. The devices beneficially may be pressure-side cleaners attached indirectly to outlets of water-circulation pumps. The supply of pressurized water travelling from a pump to such a device may be employed for various purposes, including directing debris-laden water to or near tops of debris collection chambers. The water exiting nozzles associated with the devices may push, rather than pull, the debris-laden water toward the collection chambers. Some nozzles may be oriented approximately parallel to a to-be-cleaned pool surface, and curved tubes may be employed to direct water and debris flow to perimeters of the cleaners.

摘要： An internal valve includes a valve stem disposed in a valve body, a poppet valve coupled to the stem, and a bleed valve coupled to the stem. The valve stem is shiftable from a first position in which the poppet valve and the bleed valve are closed, to a second position in which the bleed valve is open, and a third position in which the bleed valve is closed and the poppet valve is open, and the poppet may close in response to a pressure change. The internal valve includes a strainer having an extended portion to be positioned in a clearance space between an upper portion of the valve body and an opening of a fluid container. The strainer is arranged for securement to a mounting area of the valve body by at least one fastener.

摘要： A disposable filter for a sink including a substantially inverted disposed conical filter having a rounded conical apex and a continuous horizontally disposed circular bottom rim. A circular top rim is continuously disposed on a top surface of the bottom rim of the filter. A concave-shaped indentation is continuously disposed through each of an exterior edge of the bottom rim and an outer surface of the top rim. A plurality of tabs is attached to the outer surface of the top rim. An adhesive layer is disposed on a bottom surface of the bottom rim of the filter. The filter is removably disposed atop an exterior surface of a sink, with an exterior edge of the indentation disposed around an exterior surface of a base of a faucet.
