Abstract
The utility model relates to a piston type control valve for hydraulic pile hammers of various kinds, comprising a valve body 10 and a valve piston 2 in the valve body 10. High voltage in a system pressure pipeline 30 can hold the valve piston and a gravity hammer connected with the valve piston through passages 11, 25, 24 and 12. When the pressure in one pipeline 40 is reduced, under the function of the inner pressure of the passages 12 and 14, the valve piston is moved right. Simultaneously the passage 12 is communicated with a low-voltage liquid return pipeline 50 by the passages 26 and 13. The upper side 83 of the valve piston 81 is communicated with the lower side 84 of the valve piston 81 into one body. The pressure enforced in the control pipeline 40 pushes the valve piston to move left. In this way, the circulation is conducted repeatedly. The utility model can be applied for various pile devices. The utility model has the advantages of convenient manufacture and operation, and low cost.
