On the basis of technique scheme, the utility model can also be done following improvement.
Further, described valve cylinder body interior is provided with the stepped circular hole portion of four sections different inner diameters, and first section circular hole portion is: from the inside through hole of the pin end of valve cylinder body; Second section circular hole portion is: first section circular hole portion place is inside from the valve cylinder body, and internal diameter is greater than the through hole of first section circular hole portion; The 3rd section circular hole portion is: second section circular hole portion place is inside from body, and internal diameter is greater than the through hole of second section circular hole portion; The 4th section circular hole portion is: the box end from the 3rd section circular hole portion to the valve cylinder body, and internal diameter is greater than the through hole of the 3rd section circular hole portion.
Further, described valve cylinder also comprises wear-resistant sleeve, is installed in described body the 3rd circular hole portion.
Further, described wear-resistant sleeve adopts stainless steel.
The beneficial effect that adopts above-mentioned further scheme is that the wear-resistant sleeve abrasion-resistance of stainless steel is good, even and dash to damage and also to be convenient to change, because wear-resisting jacket wall is very thin, use material seldom, therefore with low cost, adopt improve nearly twice the application life of this kind mode valve cylinder, effectiveness is fairly obvious.
Further described valve cylinder the 3rd circular hole portion is along a plurality of round tube holes of valve cylinder circumference uniform distribution, and round tube hole is communicated with this inside and outside.
Adopt the beneficial effect of above-mentioned further scheme to be, a part of mud can be discharged from round tube hole, prevents the inner accumulation of mud of valve cylinder, influences stem movement.
Moreover the utility model provides a kind of wireless drilling inclinometers impulse generator main valve assembly, comprises valve cylinder, wear ring, and main spring, the signal valve rod, guide shoe, piston cap, y-type seal ring and O RunddichtringO and main valve head, wherein valve cylinder is made by beryllium-bronze material.
At last, the utility model provides a kind of wireless drilling inclinometers impulse generator main valve assembly,
