摘要： Various examples are provided related to low pressure delivery, e.g., less than 250 psi at the point of application, of plural component system from unpressurized parts A and B material supplies. In one example, a system includes a polyurethane spray foam (“SPF”) raw material supply including parts A and B and a fluid handling system that can deliver the SPF raw material at low pressure to a metal spray gun in metered amounts through separate material fluid paths/conduits via a heated hose length and a whip hose. The fluid handling system can also deliver air at low pressure to the spray gun through separate air stream paths so that the air is communicated to the part A and B material conduits forward of the part A and B material input locations, where they are supplied separately to a mixing nozzle that is engaged at an end of the spray gun.

摘要： An apparatus and method for depositing an aerosol that has an ultrafast pneumatic, shutter. The flow of aerosol through the entire deposition flow path is surrounded by at least one sheath gas, thereby greatly increasing reliability. The distance between the aerosol switching chamber and a reverse gas flow chamber input is minimized to reduce switching time. The distance from the switching chamber to the nozzle exit is also minimized to reduce switching time. The gas flows in the system are configured to maintain a substantially constant pressure in the system, and consequently substantially constant flow rates through the deposition nozzle and exhaust nozzle, to minimize on/off switching times. This enables the system to have a switching time of less than 10 ms.

摘要： The present disclosure provides an aerosol unit for an aerosol dispenser. The aerosol unit includes an axially oriented body, having a distal inlet part and a proximal outlet part. The aerosol unit also includes a carrier member arranged in the body, transversally to the axis between the inlet part and the outlet part. The carrier member includes through-holes which place the inlet part in fluid communication with the outlet part, and the carrier member is insert-moulded into the body such that a contact surface between the carrier and the body forms an air-tight seal.

摘要： Provided are a water outlet device (1) and an intelligent closestool. The water outlet device (1) includes a core (100). The core (100) includes a mixing chamber (110), one or more first water inlets (120), one or more second water inlets (130), and a water outlet (140). The water outlet (140) connects with the mixing chamber (110). A tangential direction, a radial direction, and an axial direction of the mixing chamber (110) are defined. The one or more first water inlets (120) are disposed in the mixing chamber (110) along the tangential direction so that a water flow entering the mixing chamber (110) from the one or more first water inlets (120) is capable of forming a vortex. The one or more second water inlets (130) are disposed in the mixing chamber (110) along the axial direction or the radial direction so that a water flow entering the mixing chamber (110) from the one or more second water inlets (130) is capable of forming a stable water flow. The water outlet is capable of spraying water flows in different states by adjusting the water intake ratio of the one or more first water inlets (120) and the one or more second water inlets (130).

摘要： A mix chamber for a plural component sprayer is configured to receive first and second component materials and emit a spray of a resulting plural component material. The mix chamber includes a chamber body extending between a first end and a second end and including flat lateral sides. A ramp feature is disposed proximate the first end and is configured to contact and push first and second side seals, respectively, away from a body axis as the mix chamber shifts in a first direction through a cartridge bore to increase a gap between the first side seal and the second side seal such that the first side seal engages the first flat lateral side and the second side seal engages the second flat lateral side.

摘要： A robot end effector (100) for dispensing an extrudable substance (102) comprises a chassis (110), a static mixer (101), and cartridge bays (122), extending from the chassis (110). Each of the cartridge bays (122) is shaped to receive a corresponding one of the two-part cartridges (104). Fluidic communication between the selected one of the two-part cartridges (104) and the static mixer (101) is established when the cartridge bays (122) are moved to a predetermined position with respect to the chassis (110). The robot end effector (100) comprises a dispensing valve (130), attached to the chassis (110), and a head assembly (150), comprising pairs of fittings (152). Each of the pairs of fittings (152) is configured to selectively supply compressed air from a pressure source (199) to contents of a corresponding one of the two-part cartridges (104).

摘要： A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

摘要： A device for adjusting air pressure of a spray gun, and a method for adjusting air pressure of a spray gun includes installing an air adjustment valve in a first chamber located at the rear end of a rear path of the spray gun. The spray gun is connected with a compressor and the users operates the air adjustment valve to reduce the pressure in the first chamber, and the second chamber is supplied with a pre-set pressure so as to stably provide constant pressure to the front path to proceed paint spraying task.
