(2) food companies such as milk, juice, beer industry, and pharmaceutical factory and other facilities and pipelines, the proposed use of austenitic stainless steel, tight pattern cone plug valves. Because of simple structure, fast disease (open and close 1/4 q turns the cork can complete opening and closing action) , the operation is convenient, fluid resistance small, until now is still widely used. (4) oil mining, natural gas mining, the branch pipeline, refining and cleaning facilities, nominal pressure level is greater than the Class7500, nominal diameter and larger than 900 mm, office temperature is not higher than 340 ℃, proposed to choose oil seal type cone plug valves. (5) in the large chemical industry, including pipeline and facilities of corrosive medium, requiring open or closed fast, for eau forte based media can choose teflon sleeve tightly closed cone plug valves; For medium with CH3COOH as the base, can choose Crl8Nil 2 m02ti stainless steel with ptfe sleeve tightly closed cone plug valves. It easy for multi-channel structure, so that a valve can obtain Marine valves have two, three or even four different port, so can simplify the presupposition of pipeline system, impairment of the Industrial Valves gate dosage and facility needs a bit of a petition in accessories. ( 3) Plug valve is in the history of the earliest is considered by many suitable valves. ( 4) On the basis of the structure of the cock unique place and function of can achieve, by default, can choose according to the following lists principles. Up to now is mainly used in low pressure, small and medium under the condition of temperature is not high. 6 in the hvac system in liquefied petroleum gas, natural gas, pipelines and facilities, nominal diameter greater than 200 nm, appropriate chooses packing type cone plug valves. (3) oil mining, natural gas field excavation, the branch pipeline, refining and cleaning facilities, nominal pressure level is greater than the Class300 and nominal diameter and larger than 300 mm, oil seal type cone plug valve is used in the proposal. (1) for distribution medium and change the media flow direction, the temperature is not higher than 300 ℃, nominal pressure PN 1 or less. 6 mpa, half is greater than the nominal diameter of 300 mm, many pathways cock valve is used in the proposal. Q: on the choice of the cock valve and plug valve structure of the unique place: answer: ( 1) Dc plug valves fluid after, small resistance, convenient, quick opening and closing. 。 ( 2) Plug valve in the pipeline is mainly used for truncation, and change the medium flow direction. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
