调速卸荷阀

Speed regulation relief valve

Abstract

The utility model relates to a speed regulation relief valve, which comprises a hand wheel, a valve seat, a valve spool and a valve body. The valve spool is placed inside the valve seat, the valve seat in installed on the valve body, the hand wheel capable of rotating through 180 degrees is installed at the outer end of the valve spool, two holes with different shapes are arranged on the upper portion and the lower portion of the middle of the valve spool, positions of two holes which are simultaneously arranged on the valve seat respectively corespond to two holes on the valve seat, the positions of the two pair of holes respectively correspond to each other, the two pairs of holes are differently distributed, and the shapes of the holes are different. The speed regulation relief valve can rapidly stop an oil way in mechanical processing process, and realizes speed regulation without increasing system pressure.
本实用新型公开了一种调速卸荷阀,调速卸荷阀由手轮、阀座、阀芯、阀体组成;阀芯置于阀座内,阀座安装在阀体上,在阀芯的外端部装有一个可180度旋转的手轮,在阀芯的中间上下不同部位,开有两个不同形状的孔,在阀座与阀芯相对应的位置,同样开有两个孔,两对孔的上下位置分别对应,分布不同,孔的形状也不相同。采用新型调速卸荷阀,可使机械加工过程中,快速截止油路,不增加系统压力来实现调速。
