The utility model content
Technical problem to be solved in the utility model is to provide a kind of rolling machine hydraulic system, so that the pressure in first and second oil pipe is balanced under packing state.
The technical solution of the utility model is as follows: a kind of rolling machine hydraulic system, comprise first and second magnetic valve, both are two-position four-way valve, wherein the A of first magnetic valve end series connection check valve is after first oil pipe is connected to the hydraulic cylinder group, on first oil pipe between this hydraulic cylinder group and the check valve, be connected to first bypass pipe, be parallel with ball valve after this first bypass pipe connects accumulator; The A end series connection check valve of described second magnetic valve is after second oil pipe is connected to the hydraulic cylinder group, on second oil pipe between this hydraulic cylinder group and the check valve, be connected to second bypass pipe, after connecing accumulator, this second bypass pipe is parallel with ball valve, its key is: described first bypass pipe is communicated with through the 3rd oil pipe with second bypass pipe, and on the 3rd oil pipe ball valve is housed.
The utility model is communicated with second bypass pipe described first bypass pipe, and on the 3rd oil pipe ball valve is housed on the basis of traditional structure through the 3rd oil pipe.Adopt above technical scheme, the utility model can make the isostasy in first and second oil pipe, so just can guarantee the thrust unanimity of two hydraulic cylinder groups to roll squeezer movable roll left and right side bearing block, thereby effectively reduce noise, reduce vibrations, improve the stable working of roll squeezer, be not only applicable to cement manufacturing industry, and can promote the use on a large scale.
For the length that reduces the 3rd oil pipe, save cost, special left end with described the 3rd oil pipe is connected on first bypass pipe between accumulator and the ball valve, its right-hand member is connected on second bypass pipe between accumulator and the ball valve.
In order to improve automaticity, elect described ball valve as Solenoid ball valve.
Beneficial effect: the utility model is simple in structure, easy to make, can make the isostasy in first and second oil pipe, so just can guarantee the thrust unanimity of two hydraulic cylinder groups to roll squeezer movable roll left and right side bearing block, thereby effectively reduce the roll squeezer noise, reduce vibrations, improve the stable working of roll squeezer.
