调速节流阀valveflow流阀阀芯 7.4调速阀FlowControlValve根据“流量负反馈”原理设计而成的流量阀称为调速阀。根据“串联减压式”和“并联溢流式”之差别,又分为调速阀和溢流节流阀两种主要类型,调速阀中又有普通调速阀和温度补偿型调速阀两种结构。调速阀和节流阀在液压系统中的应用基本相同,主要与定量泵、溢流阀组...

专利名称:Flow control valve 发明人:Raymond Keiper 申请号:US07/803987 申请日:19911209 公开号:US05183077A 公开日:19930202 专利内容由知识产权出版社提供 摘要:A flow control valve includes a body having a spherical hollow central section into which a spherical central body fits. Three fluid flow...
The valve operates to control the mass flow rate between a condenser and an evaporator by regulating the effective opening area,Seff. The mass flow rate is where: vinis the inlet specific volume, or the fluid volume per unit mass.
A fluid flow control valve for a fixture having a conduit for the passage of a fluid through the fixture comprises a valve rod that is manually slideable through a hole in the fixture to intercept the conduit at right angles. The rod has a plurality of various apertures through the diameter...
A fluid flow control valve assembly has a housing with first and second ports, and a valve mechanism for controlling fluid flow by closing either port or permitting fluid flow between them. The valve
