22、re of minimum 50 psi (350 kPa). 1.2 Hoze nozzle valves covered by these requirements are intended for use with one or more of the following as applicable: a) Gasoline formulated in accordance with the Standard Specication for Automotive Spark- Ignition Fuel, ASTM D4814; b) Gasoline/ethanol blends wi

23、th nominal ethanol concentrations up to 25 percent ethanol (E25), consisting of gasoline formulated in accordance with the Standard Specication for Automotive Spark-Ignition Fuel, ASTM D4814, when blended with denatured fuel ethanol formulated to be consistent with the Standard Specication for Denat

24、ured Fuel Ethanol for Blending With Gasolines For Use as Automotive Spark-Ignition Engine Fuel, ASTM D4806; or c) Gasoline/ethanol blends with nominal ethanol concentrations above 25 percent formulated in accordance with the Standard Specication in item (b) or formulated in accordance with the Stand

25、ard Specication for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines, ASTM D5798. 1.3 These requirements cover hose nozzle valves of the manually operated and automatic pressure operated type. When they form a part of an assembly which provides for additional functions or serv

26、ice, the requirements are outside the scope of these requirements. 1.4 These requirements do not cover the following: a) Hose nozzle valves for handling liquids under cryogenic conditions. b) Hose nozzle valves for general renery service, offshore and pipe line terminals, natural gas processing plan

27、ts, gas distribution systems, petrochemical processing facilities, or the like. c) Hose nozzle valves operated wholly or partially by electricity or battery. 1.5 This standard does not cover hose nozzle valves for use with diesel, biodiesel, diesel/biodiesel blends, kerosene or fuel oil, which are c

29、TRIBUTION WITHOUT PERMISSION FROM UL 1.6 This standard does not cover hose nozzle valves for use with liqueed petroleum gas (LP-Gas), which are covered under the Standard for Flow Control Valves for Anhydrous Ammonia and LP-Gas, UL 125. 1.7 Requirements for the installation and use of these dispensi

30、ng devices are included in the Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A. 2 General 2.1 Components 2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply with the requirements for that component. 2.1.2 A component is not requir

31、ed to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance with its rating establis

32、hed for the intended conditions of use. 2.1.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only und

33、er those specic conditions. 2.1.5 A hose nozzle valve with an integral swivel shall be additionally evaluated to the Electrical-Continuity and Operation Tests in the Standard for Emergency Breakaway Fittings, Swivel Connectors and Pipe-Connection Fittings for Gasoline and Gasoline/Ethanol Blends wit

34、h Nominal Ethanol Concentrations up to 85 Percent (E0 E85), UL 567A. The force is to be applied at the point on the swivel farthest from the joint. When necessitated by the swivel construction, this test is to be conducted on additional samples of the swivel with the load applied on the opposite sid

35、e of the plane of rotation. See UL 567A, Figures 16.1 16.3 for examples.

36、 in parentheses are explanatory or approximate information. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 3 Glossary 3.1 For the purpose of this

37、 standard, the following denitions apply. 3.2 BLENDING OPTION Dispensing devices may be provided with an option that blends two specic fuels into one fuel to be dispensed. This blending occurs at the dispenser level and can be in two forms: a) Fixed blending Blending at the dispenser level that blen

38、ds two specic fuels into one fuel to be dispensed, and that fuel to be dispensed is xed. For example, xed blending includes blend options where gasoline and denatured fuel ethanol can be blended to achieve E85, which is the actual dispensed fuel. b) Variable blending Blending at the dispenser level

39、that blends two specic fuels into the fuel to be dispensed, but the fuel to be dispensed can be any of a number of previously set points. For example, variable blending includes blend options where gasoline and E85 can be blended to achieve E40, E60, and E85 as the actual dispensed fuel. 3.3 GASOLIN

40、E/ETHANOL BLENDS Blended fuels composed of a gasoline component and an ethanol component. The numerical value corresponding to the ethanol component determines the blend rating (such as E85 for 85% ethanol, 15% gasoline). 3.4 HOSE NOZZLE VALVE, AUTOMATIC A hose nozzle valve which is held open during

41、 the entire lling operation. It may be held open by manual force or by an integral hold-open or latching device. It incorporates a mechanism that shuts off the ow of liquid during refueling operations to prevent overow from the ll opening when liquid reaches a predetermined point on the spout. 3.5 H

42、OSE NOZZLE VALVES A self-closing device designed to control the ow of ammable and combustible liquids at an operating pressure of minimum 50 psi (345 kPa). It is intended for use at the outlet end of a hose for dispensing ammable liquids. 3.6 HOSE NOZZLE VALVE, MANUALLY OPERATED A hose nozzle valve

43、that is manually held open during the entire lling operation and closes only upon release of the manual force. 3.7 HOSE NOZZLE VALVE, VAPOR RECOVERY A system constructed to capture vapors displaced during lling operations. The vapors are not processed during the course of this activity. a) Assist No

44、zzle A vacuum or pump is used to draw the vapors back to tank. b) Balance Nozzle Displacement of vapors from tank being ll forces the vapor back into the storage tank.

45、UL 3.8 SEALS, DYNAMIC A seal that is subject to mechanical movement or other applied forces that result in movement or exing of the seal under normal use conditions. 3.9 SEALS, STATIC A seal that is not subject to mechanical movement or other applied forces other than compressing forces that are app

46、lied during installation, after which, the seal is held in place during normal use conditions. CONSTRUCTION 4 Assembly 4.1 General 4.1.1 A hose nozzle valve shall include all of the components required for its intended function and installation. 4.1.2 A seat disc shall be attached to its poppet or h

47、older or otherwise assembled so as to prevent it from becoming dislocated under service conditions as determined by the Hose Nozzle Endurance Test, Section 18. The means to secure the disc shall not rely upon cement or adhesive. 4.1.3 A brazing material used for joining liquid conning parts of a val

48、ve shall have a melting point (solidus temperature) of minimum 538C (1000F). 4.2 Hose nozzle valves 4.2.1 A hose nozzle valve shall be of the manually-operated or of the automatic type. A manually-operated valve requires the valve to be manually held open during the entire lling operation without th

49、e aid of hold-open devices or latches, but is capable of closing automatically. An automatic valve requires the valve to: a) Be manually opened, but is capable of being held open during the lling operation by a latch or other device; and b) Is provided with automatic closing features. Exception: A hose nozzle valve for use in salt water or boat yard environments shall be of the automatic closing type without a latch-open device. 4.2.2 Automatic hose nozzle valves equ
