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 clearly understand, 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, be not intended to limit the present invention.
As shown in Figure 1, the secondary active lubrication device of a kind of guiding valve for railway vehicle control valve, described control valve comprises control valve body 1, the slide valve buckle 4 being arranged on the guiding valve 3 in the valve chamber 2 of control valve body 1 and being arranged between control valve body 1 and guiding valve 3, described guiding valve 3 forms guiding valve pair 5 with slide valve buckle 4, the secondary active lubrication device of described guiding valve comprises the installation valve body 6 that is connected with control valve body 1 and is arranged on to be installed in valve body 6, below valve chamber 2 and the oil sump 7 be communicated with it, described valve chamber pressure can change with the not same-action of control valve, described slide valve buckle 4 is provided with oil circuit 8, described oil sump 7 by line check valve 9 be arranged on oil storage path 10 one end of installing in valve body 6 and be communicated with, the other end of described oil storage path 10 by oil outlet one-way valve 11 be arranged on control valve body 1 and be communicated with fuel-displaced path 12 one end of installing in valve body 6, the other end of described fuel-displaced path 12 is communicated with oil circuit 8 one end be 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 the equalizing piston 14 that is arranged in balance cylinder 13 and balance spring 15, balance cylinder 13 interior separation is relatively independent two-part up and down by described equalizing piston 14, its underpart is communicated with oil storage path 10, described balance spring 15 to be socketed on equalizing piston 14 and its lower end abutment in equalizing piston 14 upper-end surface, upper end is resisted against balance cylinder 13 upper inside wall, when assembling initial position, described equalizing piston 14 is in bottom balance cylinder 13 under self gravitation and the effect of balance spring 15 elastic force, top enfeoffment in described balance cylinder 13 has an atmospheric pressurized air, in described balance cylinder 13, rubber diaphragm 16 is provided with above equalizing piston 14, described rubber diaphragm 16 bottom is socketed on equalizing piston 14, its upper end is resisted against the positive stop lug boss place in balance cylinder 13, two-part up and down that the setting of rubber diaphragm can make equalizing piston be isolated by balance cylinder are more reliable.
This device is arranged in the control valve of guiding valve side effect, the pressure change of valve chamber itself is utilized to carry out the opening and closing of one-way valve in drive unit, simultaneously, the Volume Changes of balance cylinder internal pressure air is relied on constantly to be drawn in device by lubricant oil, and being incorporated into guiding valve pair from interior oil circuit of establishing, unnecessary lubricant oil again can flow in oil sump through slide face and recycle.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 are all in closed condition by spring force, equalizing piston is also because self gravitation and balance spring force are in bottom balance cylinder, 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 circuit on the right side of oil outlet one-way valve leads to guiding valve pair, and the same valve chamber of pressure change, therefore, oil outlet one-way valve is sealed by pressurized gas, is 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 now balance cylinder inner air pressure becomes higher than valve chamber inner air pressure, on the right side of oil outlet one-way valve, 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 lubricant oil through opening of equalizing piston bottom pumps into valve inner oil circuit.Like this, the lubricant oil in oil sump, through suction repeatedly with after pumping action, finally can cause on slide face through valve inner oil circuit, thus makes 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 amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
