Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 2, a kind of many grades of regulators, comprise valve seat 1, valve seat 1 is provided with S. A. 2, control handle 3, compression indicator 4, connector assembly 5, inhibiting device 6, joint 7, first blowdown valve 81, second blowdown valve 82 and the 3rd blowdown valve 83, described S. A. 2 is fixed in valve seat 1, can be rotated about axis, described S. A. 2 two ends are provided with sealed groove, be provided with shaft block ring groove outside S. A. 2 and adopt shaft block ring and valve seat 1 to fix, multiple radial direction oil is provided with in the middle part of described S. A. 2, can with the first blowdown valve 81, the oil duct of the second blowdown valve 82 and the 3rd blowdown valve 83 communicates, described S. A. 2 one end is provided with many groups for mounting spring 10, the through hole of spacing steel ball 11, S. A. 2 is provided with two groups of seal rings, described inhibiting device 6 overlaps 9 by calibration, spring 10, spacing steel ball 11, locating dowel pin 12 forms, described calibration cover 9 is provided with the many groups hole by gear angular distribution, it is inner that described calibration cover 9 is fixed on valve seat 1 by locating dowel pin 12, described spring 10, steel ball 11 is located in S. A. 2 radial hole, when steel ball 11 enters in the through hole on calibration cover 9 at every turn, represent a gear, described control handle 3 adopts holding screw to be fixed in S. A. 2 radial hole, by controlling described control handle 3, get to appointment one gear that described valve seat 1 identifies, the object of switch operating pressure can be reached.
Spring 10 in inhibiting device 6, steel ball 11 rotate with S. A. 2, and during every gear, part enters in calibration cover 9 by steel ball 11.
As shown in Figure 3, described valve seat 1 be provided with clear, understand, be easy to identify gear mark 1,2,3, X.
