Insect shaped sprinkler nozzle have safety and real shaped touch of sense and legs, and have the function of water supply from one part of its body to the direction of dripping, 90 degrees, 180 degrees, 360 degrees or mist spray.
摘要:
A microprocessor-operated valve is held in a showerhead to shut off flow of water if a leak detector measures any water leakage. The valve is mounted in a conduit in the showerhead and operated to shut off water flow if the water leak detector senses leakage from the showerhead. An electric motor is held in the showerhead and actuated to drive a gear train to close the normally-open valve and shut off water flow through the conduit.
摘要:
A universal head for fixing a nozzle to a fluid distribution duct comprises a cap-like sleeve adapted to be associated with the outlet of the duct, a nozzle insertion slot formed at the top of the sleeve, and wings for locking the nozzle that can expand radially and are formed proximate to the slot.

An apparatus and method for applying adhesive in a web converting machine is disclosed. In some embodiments, an adhesive application assembly is used to seal the tail of a rolled product against the rolled product. After being positioned in a location upon a roller, the rolled product is rotated and a sensor detects the location of the tail end, thereby establishing a reference for determining tail length in later operations. When the tail reaches a desired position, the adhesive application assembly applies adhesive to the tail and/or rolled product. In some embodiments, the adhesive assembly includes one or more adhesive sprayers with aperture members, and is self-cleaning. After the adhesive has been applied, the tail is wound upon the rolled product. In some embodiments, an adhesive application assembly is employed to apply adhesive to a core about which sheet material is to be wound.

A fuel injection valve including an orifice plate having a plurality of injection orifices, a valve seat in the upstream section of the injection orifices and has a cylindrical fuel flow path formed therein, a fuel cavity formed between the fuel flow path and the orifice plate directly above the injection orifices, and a valve member supported for its reciprocations to settle in and lift off the valve seat. The relationships among dimensions are nullD1nullnulld
摘要:
A two doctor blade laminating and coating system is employed with a gravure or flexographic set up to coat adhesive onto a film and then laminate it to another film. The adhesive is pumped into the chamber and a sump receives adhesive recirculated back from the enclosed chamber. Adhesive is mixed and supplied to the sump while the process is being conducted so that the enclosed chamber is continuously full of adhesive. The preferred adhesive is a two-stage epoxy having part A and part B mixed together in a desired ratio. The adhesive is a zero VOC 100% solids laminating adhesive having a mixed viscosity of 200-1500 cps with the viscosity remaining within a desired range at room temperature, defined as a temperature range of 50-100 degrees F. for up to 3 hours. The adhesive is solventless and is unaffected by moisture. The adhesive consists of ingredients which make it permissible for use as an adhesive for laminations of films designed for food packaging pursuant to F.D.A. Regulation 175.105. The adhesive is formulated to avoid emission of odors and can be used in a four or five roll coating system.
摘要:
A method for producing a re-releasable bond between two wafers which is stable at high temperatures and mechanically stable is described. The two wafers to be bonded are placed one on top of the other in such a way that a surface of the first wafer is disposed on a surface of the second wafer. Interspaces at least partially connecting the surfaces are created between the wafers. A liquid glass compound is introduced into the interspaces in such a way that a liquid glass film wetting the inner surfaces of the interspaces is formed, in which process voids that are connected to the atmosphere surrounding the wafers remain inside the interspaces wetted with the liquid glass compound. To transform the wetting liquid glass film into a solid silicon dioxide film, the wafers lying one on top of the other are subjected to a temperature treatment.
摘要:
The invention relates to a fuel injection valve which is characterized in that it possesses a multilayer swirl valve (30) downstream from a valve seat (15) shaped onto a valve seat element (13), at least these two components being installed from the inflow direction into a passthrough opening (10) of a valve seat support (9). The valve seat support (9) has a lower base region (17) that provides for a reduction in the cross section of the passthrough opening (10) downstream from the valve seat (15). The fuel injection valve is suitable in particular for direct injection of fuel into a combustion chamber of a mixture-compressing, spark-ignited internal combustion engine.
