摘要:
A coated stainless steel article and a method of preparing the article are disclosed. The coating is a plasma chemical vapor deposited coating, formed from a plasma of nitrous oxide, a silane, and an energy transfer agent (such as He, Ar). The resulting coating is adherent, corrosion resistant, and has a thickness sufficient to mask and cover the features of the stainless steel substrate, and to provide a pitting potential (in 3.5% NaCl) of greater than 600 millivolts, a J.I.S. 8502 (1982) versus a saturated calomel electrode a salt spray test rating in 5% NaCl-0.02% hydrogen peroxide of at least B.
摘要:
A sanitary fitted element (1) which can be inserted into the water outlet of a sanitary outlet fitting and is held releasably there. A characteristic feature of the fitted element (1) according to the invention is that said fitted element has an adjusting device for changing the clear sectional area of flow of the fitted element (1) and/or the discharge rate, which adjusting device is actuable via at least one control element (8) which is arranged actuably on the inflow side of the fitted element (1) and/or on the outflow side thereof. The fitted element (1) according to the invention can be used in a versatile manner in order to reduce the outlay on production and stock.
摘要:
A flow regulator (1) having a regulator housing (2) with a control peg (4) in a passage channel that encompasses an annular flow restrictor (5) made of elastic material. The flow restrictor defines a control gap (6) located between itself and at least one part that is fixed to the housing. The passage cross-section of the gap can be modified by deformation of the flow restrictor resulting from the difference in pressure during cross flow. Spaced recesses (7, 8) oriented in the flow direction are provided in a peripheral direction on the surfaces of the part fixed to the housing defining the control gap (6). The regulation recesses are on the inner surface of the regulator housing (2) and on the peripheral surface of the control peg. The desired flow rate is achieved at comparatively low liquid pressure and remains practically constant in case of increased or fluctuating liquid pressures.
