The common specification of the passage of these guide's control loops and functional element is less, but One's name is legion, the changes of function complexity.Simultaneously, the aperture of quite a few guide's control loop passage, need to adopt standardized what is called " plug screw " (such as meeting ISO261 (M), ISO228/BSPP (G), standard plug screws such as DW908/910) to be sealed with metric system or connecting thread made in Great Britain.
Application and practice show, in the current commercially available two-way plug-in valve control unit, in nearly all flange control cover plate product, the inner guide who is provided with controls functional element and the aperture plug screw all has independently form, and is installed in respectively in the passage of guide's control loop or in the aperture.The layout of the traditional approach of this separated type is not only made troubles to the design of the guide's control loop in the two-way plug-in valve control cover plate.Especially when flange-type control cover plate inside configuration guide control loop is comparatively complicated, the layout difficulty, certainly will cause the feature dimension and the weight of the block of the cover plate body of control cover plate or control valve piece to increase, simultaneously, considerable part is too much kind, specification and the unnecessary variation that forms after the functional element owing to having adopted different sort-type guides to control in the existing flange-type control cover plate product.
In two-way plug-in valve flange control cover plate another important structural element be on its cover plate body except the inside attachment face that the bottom must be provided with, in the end face and the side of cover plate body, especially also often be provided with outside attachment face at end face.Outside attachment face is used for installing the combination of the pilot-actuated valve and the overlapping thereof of employing standard.Current in the nearly all two-way plug-in valve flange control cover plate product of commercially available inside nominal diameter in the following Dimensions of NG50, mostly having adopted the pilot-actuated valve that meets the outside attachment face of corresponding specification in the ISO4401-03 class standard, is solenoid directional control valve or its stack combinations in a large number.And all show by theoretical theory analysis and the application practice to hydraulic pilot control network of liquid resistance, for than small dimension, for example for guide's control of the two-way plug-in valve control unit of NG16, specifications such as 25, the pilot-actuated valve that adopts corresponding specification in the ISO4401-03 class standard is its some important technological parameters in many cases, flow for example, be far longer than actual need flow, flow controller (plug screw etc.) is set in the cover plate body in a large number to such an extent as to have to, cause the complex structure in guide's controlled stage, control owes reasonable etc.
