球阀有几种叫法 根据执行器分,球阀可以叫气动球阀/电动球阀。根据球阀的阀体是否可拆卸,可分一片式、二片式、三片式球阀。一片式球阀,阀体紧凑,经济实惠;二片式和三片式阀门,便于球阀的维护和置换。根据球阀的通道数量,可分二通、三通球阀。二通球阀应用非常广泛,根据通道内外直径是否一致,可分全径球阀和缩径球阀,缩径球阀的内部直径比外部直径小,会减小介质流量,但更耐压;三通球阀根据内部球体形状,可分L型、T型球阀,L型球阀起换向作用,T型球阀可起换向和混合作用,应用也相当广泛。 球阀也叫开关阀。 译文: What are the name for ball valve Points according to the actuator, ball valve pneumatic valve can be called / electric valve. According to whether the removable valve body can be divided into one-piece, two piece, three-piece ball valve. A ball valve, the valve body compact, cost-effective; two-and three valves, ball valves to facilitate maintenance and replacement. According to the number of channels ball can be divided into two-, three-ball. Two-way valve is widely used, according to the channel are the same inside and outside diameter, can be divided into full bore and reduced bore ball valve, reduced bore ball valve of the internal diameter than the external diameter of small, medium flow will be reduced, but more pressure; way ball valve according to the internal shape of a sphere can be divided into L-, T-ball, L-ball play for the role, T-ball and can play for the mixing, the application is quite extensive. Ball also called off valve. |
