(2) background technique
Present two-way plug-in valve field, the maximum diameter of international standard ISO/DP7368 regulation is Dg160, so at home and abroad the maximum diameter maximum of two-way plug-in valve is exactly the Dg160 latus rectum.Fast development along with large-scale stamp forging hydraulic press, large free forging hydraulic machine and other big machinery equipment, the two-way plug-in valve of Dg160 latus rectum can not satisfy the demand of large hydraulic system development, and in the process of making big latus rectum cartridge valve, reasonably installation question needs people to solve.
(3) summary of the invention
The present invention provides the Dg250 latus rectum high-pressure high-flow two-way plug-in valve mounting mechanism of a kind of reliable performance, safety and stability in order to remedy the defective of prior art.
The present invention is achieved through the following technical solutions:
A kind of Dg250 latus rectum high-pressure high-flow two-way plug-in valve mounting mechanism, comprise valve body, it is characterized in that: the valve body top is provided with four uniform plug-in unit mounting holes, and the valve body top is provided with positioning pin hole and control cover plate mounting screw hole, and valve inner is provided with the oily runner of control hole.
The latus rectum of working connection is Dg250mm in this Dg250 latus rectum high-pressure high-flow two-way plug-in valve mounting mechanism, valve body, and valve body nominal operation oil pressure is 31.5Mpa, and maximum oil pressure is 42Mpa, and the control peak rate of flow is 40000L/min.The center of circle in plug-in unit mounting hole and control cover plate mounting screw hole is positioned on the same circumference, and the diameter of described circumference is 620mm.Control cover plate mounting screw hole number is 12, and symmetry is installed in that angle is 35 degree between two control cover plate mounting screw hole circle hearts of plug-in unit mounting hole both sides, and angle is 27.5 degree between two adjacent arbitrarily control cover plate mounting screw hole circle hearts.
The invention has the beneficial effects as follows: this Dg250 latus rectum high-pressure high-flow two-way plug-in valve mounting mechanism, make the working connection maximum diameter reach Dg250mm, logical oil mass is big, flexible and convenient operation, stable action, commutation is reliable, guarantees that high pressure oil has good working performance under the maximum service pressure state, use reliable, life-span is long, has realized rated working pressure 31.5Mpa under the Dg250 latus rectum condition, maximum service pressure 42Mpa, peak rate of flow 40000L/min has very big promotional value.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing 1 is looked schematic representation for the master of Dg250 latus rectum high-pressure high-flow two-way plug-in valve mounting mechanism of the present invention.
Accompanying drawing 2 is the schematic top plan view of Dg250 latus rectum high-pressure high-flow two-way plug-in valve mounting mechanism of the present invention.
Among the figure, 1 valve body, 2 working connections, 3 positioning pin holes, 4 plug-in unit mounting holes, 5 control cover plate mounting screw holes, the oily runner of 6 controls hole.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This Dg250 latus rectum high-pressure high-flow two-way plug-in valve mounting mechanism, comprise valve body 1, it is characterized in that: valve body 1 top is provided with four uniform plug-in unit mounting holes 4, and valve body 1 top is provided with positioning pin hole 3 and control cover plate mounting screw hole 5, and valve body 1 inside is provided with the oily runner of control hole 6.The latus rectum of working connection 2 is Dg250mm in the valve body 1, and valve body 1 nominal operation oil pressure is 31.5Mpa, and maximum oil pressure is 42Mpa, and the control peak rate of flow is 40000L/min.Plug-in unit mounting hole 4 is positioned on the same circumference with the center of circle in control cover plate mounting screw hole 5, and the diameter of described circumference is 620mm.Control cover plate mounting screw hole 5 numbers are 12, and symmetry is installed in that angle is 35 degree between 5 centers of circle, two control cover plate mounting screw holes of plug-in unit mounting hole 4 both sides, and angle is 27.5 degree between adjacent arbitrarily 5 centers of circle, two control cover plate mounting screw holes.
