Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, the secondary initiatively lubricating fitting of a kind of guiding valve for railway vehicle control valve, described control valve comprises control valve body 1, be arranged on the guiding valve 3 in the valve chamber 2 of control valve body 1 and be arranged on control valve body 1 and guiding valve 3 between slide valve buckle 4, described guiding valve 3 forms guiding valve pair 5 with slide valve buckle 4, the secondary initiatively lubricating fitting of described guiding valve comprises the installation valve body 6 being connected with control valve body 1 and is arranged on to be installed in valve body 6, valve chamber 2 belows and the oil sump 7 being communicated with it, described valve chamber pressure can change with the not same-action of control valve, on described slide valve buckle 4, be provided with oil circuit 8, described oil sump 7 is communicated with oil storage path 10 one end in being arranged on installation valve body 6 by line check valve 9, the other end of described oil storage path 10 is communicated with fuel-displaced path 12 one end that are arranged on control valve body 1 and install in valve body 6 by oil outlet one-way valve 11, the other end of described fuel-displaced path 12 is communicated with oil circuit 8 one end that are arranged on slide valve buckle 4, the other end of described oil circuit 8 is arranged on secondary 5 corresponding parts of guiding valve, when assembling initial position, described in line check valve 9 and oil outlet one-way valve 11 are in closed condition.
Wherein, described oil storage path 10 is connected with oil storage balanced controls, described oil storage balanced controls comprise balance cylinder 13 and are arranged on equalizing piston 14 and the balance spring 15 in balance cylinder 13, described equalizing piston 14 is relatively independent two-part up and down by balance cylinder 13 interior separations, its underpart is communicated with oil storage path 10, described balance spring 15 be socketed on equalizing piston 14 and its lower end abutment in equalizing piston 14 upper-end surfaces, upper end is resisted against balance cylinder 13 upper inside wall, when assembling initial position, described equalizing piston 14 under self gravitation and balance spring 15 elastic force effects in balance cylinder 13 bottoms, top enfeoffment in described balance cylinder 13 has an atmospheric pressurized air, in described balance cylinder 13, equalizing piston 14 tops are provided with rubber diaphragm 16, described rubber diaphragm 16 bottoms are socketed on equalizing piston 14, its upper end is resisted against the positive stop lug boss place in balance cylinder 13, the setting of rubber diaphragm can make equalizing piston that two-part up and down of balance cylinder isolation are more reliable.
This device is arranged in the control valve of guiding valve side effect, utilize the pressure of valve chamber itself to change the switching that carrys out one-way valve in drive unit, simultaneously, rely on the Volume Changes of balance cylinder internal pressure air that lubricant oil is constantly drawn in device, and be incorporated into guiding valve pair from the interior oil circuit of establishing, unnecessary lubricant oil can again flow in oil sump and recycle through slide face.Its specific works process is:
As shown in Figure 1, assembling initial position, due to guiding valve indoor non-pressure power air, in line check valve and oil outlet one-way valve lean on spring force all in closed condition, equalizing piston is also because self gravitation and balance spring force are in balance cylinder bottom, now, in balance cylinder, envelope has 1 atmospheric pressurized air.
As shown in Figure 2, when control valve is inflated, valve chamber internal pressure raises, and in line check valve spring is compressed, in line check valve is opened, meanwhile, because oil outlet one-way valve right side oil circuit leads to guiding valve pair, the same valve chamber of pressure change, therefore, oil outlet one-way valve is sealed by pressurized gas, in close stance.Therefore, the in line check valve sucktion balance cylinder of lubricant oil through opening in oil sump, and promote equalizing piston and move upward, the air in compression balance cylinder, until balance cylinder compressed air pressure and valve chamber pressure balance.
As shown in Figure 3, when control valve reduces pressure, valve chamber internal pressure declines, and in line check valve is closed under spring force effect.Because balance cylinder inner air pressure now becomes higher than valve chamber inner air pressure, oil outlet one-way valve right side oil circuit pressure declines with valve chamber internal pressure simultaneously, therefore equalizing piston moves downward, oil outlet one-way valve is opened, and the oil outlet one-way valve of the lubricant oil of equalizing piston bottom through opening pumps into valve inner oil circuit.Like this, the lubricant oil in oil sump is through suction repeatedly and pump after action, finally can cause on slide face through valve inner oil circuit, thereby make the guiding valve vice division chief of control valve in lubricating status.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
