四川省石油管理局矿机研究大队试制成功一种850公斤/厘米~2平板阀,可以作为压裂井口的主要部件,与国产850公斤/厘米~2压裂车配合使用。 该阀阀座为浮动型。当平板阀关闭受压后,其进口端阀座的前后可以形成压力差,使阀座紧贴在阀板上,从而实现进口端密封。 Sichuan Petroleum Administration mine unit successfully developed a trial of 850 kg / cm ~ 2 flat-panel valve, can be used as a major part of the wellhead fracturing, and domestic 850 kg / cm ~ 2 fracturing truck used in conjunction. The valve seat is floating type. When the flat-plate valve is closed and pressured, the pressure difference can be formed at the front and the back of the valve seat at the inlet end, so that the valve seat is closely attached to the valve plate, so that the inlet end is sealed.
