Detailed Description
The present invention will be further described with reference to specific embodiments.
A pressure regulating floating valve group comprises a valve block, a two-position two-way electromagnetic seat valve A, a two-position two-way electromagnetic seat valve B and a three-way pressure reducing valve; the two-position two-way electromagnetic seat valve A, the two-position two-way electromagnetic seat valve B and the three-way pressure reducing valve are all arranged on the valve block, and the valve block is also provided with an oil port P, an oil port T, an oil port I1 and an oil port I2; an inlet of the three-way pressure reducing valve is communicated with the oil port P, an outlet 1 of the three-way pressure reducing valve is communicated with the oil port T, and an outlet 2 of the three-way pressure reducing valve is communicated with an inlet of the two-position two-way electromagnetic seat valve B; the inlet of the two-position two-way electromagnetic seat valve A is communicated with the outlet 1 of the three-way pressure reducing valve; the inlet of the two-position two-way electromagnetic seat valve B is communicated with the outlet 2 of the three-way pressure reducing valve; an outlet of the two-position two-way electromagnetic seat valve A is communicated with an oil port I1, and an oil port I1 is communicated with an oil way A of the hydraulic oil cylinder; an outlet of the two-position two-way electromagnetic seat valve B is communicated with an oil port I2, and the oil port I2 is communicated with an oil way B of the hydraulic oil cylinder; the oil port P is communicated with the oil supply path P, and the oil port T is communicated with the oil return path T.
The valve block is equipped with the valves mounting hole, the valves mounting hole sets up the left and right sides at the valve block, the quantity of valves mounting hole is 4, respectively has 2 about.
The three-way pressure reducing valve is arranged between the two-position two-way electromagnetic seat valve A and the two-position two-way electromagnetic seat valve B.
The snow sweeping roller of the snow sweeping vehicle is provided with a hydraulic oil cylinder for driving the snow sweeping roller to lift. When the road surface height became high, the snow sweeping roller became less apart from the ground, and the brush hair became big to ground pressure, and hydraulic cylinder bore pressure became little, and tee bend relief pressure valve export 1 was closed this moment, and hydraulic oil flowed to oil circuit B through two-position two-way solenoid valve B to make hydraulic cylinder's piston upwards, hydraulic cylinder promoted the snow sweeping roller, and the brush hair recovers to ground pressure.
When the road surface height becomes low, the distance between the snow sweeping roller and the ground is increased, the pressure of the brush bristles to the ground is reduced, the ground supporting force is reduced, and therefore the pressure born by the hydraulic oil cylinder is increased. At the moment, the outlet 2 of the three-way pressure reducing valve is closed, and hydraulic oil flows to the oil way A through the two-position two-way electromagnetic seat valve A, so that a piston of the hydraulic oil cylinder faces downwards, and the hydraulic oil cylinder drives the snow sweeping roller to descend. The pressure of the bristles to the ground is restored.
The utility model provides a unsteady valves of pressure regulating can realize adjusting the brush hair according to the operating mode and to ground pressure, help improving the work efficiency of snow sweeper and reduce the wear rate of brush hair. Just the utility model discloses an independent valves can conveniently install on the snow plough that does not have the floating function. And the upgrading and refitting cost of the old equipment is reduced.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
