Introduction the paper and structure characteristics of plug valve

     Structural characteristics

    (1).Plug valves fluid by DC, small resistance, convenient opening and closing, quickly.

    (2).Plug valves in the pipeline is mainly used for cutting, distribution and change the flow direction of medium rise. It is easy to adapt to multi channel structure, so that a valve can get two, three, or even four different channel, this simplifies the design of piping systems,reducing valve and equipment required in the amount of someconnection fittings.

    (3).Plug valve is the valve the earliest history of people used.Because of simple structure, rapid opening and closing (plug 1/4Q turn to complete the opening and closing action), convenient operation, small fluid resistance, is still widely used. Mainly used in low pressure, small caliber and medium temperature is not high case.

    (4).According to the structure characteristics and design plug valves of the function, can be used according to the followingprinciples.

    Used for distribution of media and change the flow direction of medium, its working temperature is not higher than 300 ℃, nominal pressure PN ≤ 1.6MPa, nominal diameter less than 300mm,suggested the use of multiple plug valve.

     Equipment and pipeline, milk, fruit juice, beer, food industry andpharmaceutical factory and so on, the selection of austenitic stainless steel business advice, tight set conical plug valves.

     The oil, natural gas, pipeline transportation branch, refining andcleaning equipment, nominal pressure of not more than Class300,nominal diameter less than 300mm, suggested the use of conical plug valve oil seal.

      The oil, natural gas, pipeline transportation branch, refining andcleaning equipment, nominal pressure of not more than Class7500,nominal diameter less than 900mm, the temperature is not higher than 340 ℃, suggested the use of conical plug valve oil seal.

Chain guides

      In large scale chemical industry equipment, pipeline and corrosivemedium, request to open or close the speed occasions, for using nitric acid as the base of the medium can be used Teflon sleeve conical plug valve seal; for acetic acid based medium, can choose Crl8Nil 2M02Ti stainless steel lined PTFE sleeve conical plug valve seal.

     In the pipeline gas, natural gas, HVAC systems and equipment,nominal diameter less than 200nm, should use packed type conical plug valve.
