Meanwhile, the purpose of this utility model is also to provide the circuit breaker hydraulic actuating mechanism using above-mentioned control valve.
In order to solve the problem, control valve of the present utility model is by the following technical solutions: control valve, comprise valve seat and be assemblied in the valve pocket in valve seat, control chamber and instantaneous high pressure oil pocket is provided with between valve pocket and valve seat, be communicated with throttle orifice by oily passage between control chamber with high-voltage oil cavity, throttle orifice is at one end of the close instantaneous high pressure oil pocket of oily passage and oily channel connection, described oily channel part is located on the wall of valve seat, and throttle orifice is directly located on valve seat or is located on the plug that is fixedly connected with valve seat.
Throttle orifice is located on the plug that is fixedly connected with valve seat, and described plug is the screw plug with valve seat screw-thread fit.
The outer end of described screw plug is provided with allen wrench groove.
The part be positioned on valve seat of oil passage comprises along the axially extended axial extension part of valve pocket and the radial extension part along the extension of axle sleeve radial direction, and one end of axial extension part and radial extension part close valve seat outside separately is by corresponding plug shutoff.
Circuit breaker hydraulic actuating mechanism is by the following technical solutions: circuit breaker hydraulic actuating mechanism, comprise control valve, described control valve comprises valve seat and is assemblied in the valve pocket in valve seat, control chamber and instantaneous high pressure oil pocket is provided with between valve pocket and valve seat, be communicated with throttle orifice by oily passage between control chamber with high-voltage oil cavity, throttle orifice is at one end of the close instantaneous high pressure oil pocket of oily passage and oily channel connection, described oily channel part is located on the wall of valve seat, and throttle orifice is directly located on valve seat or is located on the plug that is fixedly connected with valve seat.
Throttle orifice is located on the plug that is fixedly connected with valve seat, and described plug is the screw plug with valve seat screw-thread fit.
The outer end of described screw plug is provided with allen wrench groove.
The part be positioned on valve seat of oil passage comprises along the axially extended axial extension part of valve pocket and the radial extension part along the extension of axle sleeve radial direction, and one end of axial extension part and radial extension part close valve seat outside separately is by corresponding plug shutoff.
Because described oily channel part has been located on the wall of valve seat by control valve of the present utility model, throttle orifice be directly arranged on valve seat or be located on the plug that is fixedly connected with valve seat.Therefore, when processing, the valve seat relatively easily can processed processes throttle orifice, thus the machining apparatus such as drilling machine can be adopted directly to process throttle orifice at material, technique is simple, efficiency is high, solves the problem that the throttle orifice processing difficulties of existing control valve, work efficiency are low, less economical.
Further, adopt additional plug to arrange the structural type of throttle orifice, can beyond control valve, independent processes to throttle orifice, is more convenient to clamping and location, and can not affect the other parts of control valve in course of working.
