They are of the typ
22、e used in motor fuel dispensing equipment. Hose nozzle valves covered by this standard are for use with ammable uids which are handled at temperatures within the range of minus 29C (minus 20F) to 52C (125F) and an operating pressure of minimum 50 psi (350 kPa). 1.2 These requirements cover hose nozz
23、le valves of the manually operated and automatic pressure operated type. When they form a part of an assembly which provides for additional functions or service, the requirements are outside the scope of these requirements. 1.3 These requirements do not cover the following: a) Hose nozzle valves for
24、 handling liquids under cryogenic conditions. b) Hose nozzle valves for general renery service, offshore and pipe line terminals, natural gas processing plants, gas distribution systems, petrochemical processing facilities, or the like. c) Hose nozzle valves operated wholly or partially by electrici
25、ty or battery. 1.4 For hose nozzle valves intended to be used with gasoline/ethanol blends with nominal ethanol concentrations above 10%, refer to Outline of Investigation for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 - E85), UL 87A, for additional
26、 requirements. Revised 1.4 effective April 30, 2015 1.5 Refer to Outline of Investigation, UL 87B, for additional requirements for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations Up to 20 Percent (B20), Kerosene, and Fuel Oil. 1.6 Requirements for the insta
27、llation and use of these dispensing devices are included in the Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A.

29、 required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.1.4 Specic components are incomplete in constr
30、uction 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 under those specic conditions. 2.1.5 A hose nozzle valve with an integral swivel shall be a
31、dditionally evaluated to the Electrical-Continuity and Operation Tests in the Standard for Emergency Breakaway Fittings, Swivel Connectors and Pipe-Connection Fittings for Petroleum Products and LP-Gas, UL 567. The force is to be applied at the point on the swivel farthest from the joint. When neces
32、sitated by the swivel construction, this test is to be conducted on additional samples of the swivel with the load applied on the opposite side of the plane of rotation. See UL 567, Figures 15.1 15.3 for examples. 2.2 Units of measurement 2.2.1 When a value for measurement is followed by a value in
33、other units in parentheses, the rst stated value is the requirement. 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.

38、ZLE VALVE, AUTOMATIC A hose nozzle valve which is held open during 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 ope
39、ning when liquid reaches a predetermined point on the spout. 3.3 HOSE 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 liqu
40、ids. 3.4 HOSE NOZZLE VALVE, MANUALLY OPERATED A hose nozzle valve that is manually held open during the entire lling operation and closes only upon release of the manual force. 3.5 HOSE NOZZLE VALVE, VAPOR RECOVERY A system constructed to capture vapors displaced during lling operations. The vapors
41、are not processed during the course of this activity. a) Assist Nozzle 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. 3.6 SEALS, DYNAMIC A seal that is subject to mechanical movement o
42、r other applied forces that result in movement or exing of the seal under normal use conditions. 3.7 SEALS, STATIC A seal that is not subject to mechanical movement or other applied forces other than compressing forces that are applied during installation, after which, the seal is held in place duri

A ma
46、nually-operated valve requires the valve to be manually held open during the entire lling operation without the 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
47、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 equipped with an integr
48、al hold open or latching device shall be so designed that, if left in the latched position after the ow has been stopped by means other than the automatic feature of the hose nozzle, it shall automatically unlatch when it is returned to the dispenser, See Automatic hose nozzle valve, 15.1.2. NOTE: T
49、his includes hose nozzle valves that close with a no pressure/no ow mechanism, as well as interlock hose nozzles valves that unlatch when removed from car ll pipe or when hung on the dispenser. 4.2.3 A hose nozzle valve shall be of the normally closed type. It shall be self-closing upon the manual or automatic release of the operating lever. 4.2.4 A guard shall be provided to guide or protect the free end of an operating lever and to prevent opening of the valve or damage to
