30、roduction The vapour manifold vent valve allows the controlled release of vapour from the vapour manifold and the controlled entry of atmospheric air into the vapour manifold. It may also include a breathing function. BS EN 17110:2018EN 17110:2018 (E) 6 1 Scope This document covers the vapour manifo

31、ld vent valve used to provide controlled venting of the vapour manifold to atmosphere. It specifies the performance requirements and the critical dimensions of the vapour manifold vent valve. It also specifies the tests necessary to verify compliance of the equipment with this document. The service

32、equipment specified by this document is suitable for use with liquid petroleum products and other dangerous substances of Class 3 of ADR 1 which have a vapour pressure not exceeding 110 kPa at 50 C and petrol, and which have no sub-classification as toxic or corrosive. 2 Normative references The fol

38、provide pressure and vacuum breathing for the vapour manifold. 5 Design characteristics 5.1 General The vapour manifold vent valve shall provide a controlled vapour path between the vapour manifold and atmosphere. The vapour manifold vent valve shall be closed during the process of vapour recovery,

39、both loading and delivery. Self-operating valves shall not compromise the vapour recovery process. Such valves shall be of the resealing type, and shall be designed to prevent unauthorized adjustment of the self-operating mechanism. When not activated the valve shall return automatically to its pass

40、ive state. 5.2 Pressure and vacuum breathing When provided, the pressure and vacuum breathing characteristics shall be: pressure relief opening setting - not to exceed 12 kPa (gauge); vacuum relief opening setting - between 0,8 kPa (gauge) and 2,5 kPa (gauge). 5.3 Ingress protection The vapour manif

41、old vent valve shall be designed, or provision made, to meet the requirements of IP 21 in accordance with EN 60529. 5.4 Flow capacity A flow performance against pressure drop diagram (standard m3/h at 20 C) shall be provided by the manufacturer for pressure and/or vacuum functions. 5.5 Temperature r

42、ange Unless otherwise specified, the design temperature range shall be 20 C to +50 C. Where the vapour manifold vent valve is subjected to more severe conditions, the design temperature range shall be extended to 40 C or +70 C as applicable. 5.6 Materials of construction The manufacturer shall provi

43、de, with the equipment, a full material specification for those parts that may come into contact with the substances described in Clause 1. 5.7 Dimensional characteristics 5.7.1 Maximum dimensions Top mounted valves shall be accommodated within the tank top protection BS EN 17110:2018EN 17110:2018 (

46、h the dangerous goods and its mounting shall not exceed 1 106. Provision shall be made for the bonding of its mounting to the tank such that the electrical resistance between the two shall not exceed 10 . 6 Tests 6.1 General Two classes of tests are required: production tests and type tests. Test re

47、sults shall be recorded and maintained in accordance with the manufacturers procedures. Testing methods and procedures shall conform to EN 12266-1 and EN 12266-2 except as specified within this document. Unless otherwise specified, test medium shall be air or other suitable gas. The choice of the me

48、dium is the responsibility of the manufacturer. Where the obturator forms part of the pressure containing shell, it may be closed during strength and tightness tests. 6.2 Production tests 6.2.1 General The number, frequency and sampling methods of production test samples shall be not less than those

49、 specified within ISO 2859-1 (AQL of 2,5). Production tests shall comprise the following: internal seat tightness test; and operability test.
