Abstract

The invention relates to the technical field of cubic press, and particularly relates to a vacuum exhaust valve and a cubic press comprising such vacuum exhaust valve. The vacuum exhaust valve comprises an exhaust bolt which is provided with an exhaust hole, a lower part of the exhaust bolt is arranged in the exhaust hole through a thread and an upper part of the exhaust bolt stretches out the exhaust hole and forms an air pumping connector, a valve needle is arranged in the exhaust hole from bottom to top through penetration, the valve needle comprises a guide rod part and a blocking part, anupper end of the blocking part and a lower end face of the exhaust bolt block upwards in cooperation, a lower end blocks downwards and seals a small-diameter end of the exhaust hole, the lower end face of the exhaust bolt is provided with a transverse groove, an inner wall of the exhaust hole is provided with a vertical groove, the transverse groove and the vertical groove are correspondingly communicated so as to form an air channel for gas to flow to an air pumping hole from the exhaust hole. The vacuum exhaust valve provided by the invention has high pressure bearing capability, can adaptto exhaust requirements of an ultrahigh pressure hydraulic system, and simultaneously, is convenient for a vacuum pump to perform vacuum supply for a press cylinder, thus, exhaust efficiency is improved essentially.

Description

technical field [0001] The invention relates to the technical field of six-sided presses, in particular to a vacuum exhaust valve and a six-sided press including the same. Background technique [0002] In the field of diamond synthesis in my country, the six-sided press is the main equipment. The six-sided press has 6 pressure cylinders. The press cylinders are hydraulic cylinders, and the oil pressure can reach more than 100Mpa. Because the pressure source of the six-sided press is Six directions, so after the new assembly and maintenance of the six-sided top press, there will be more gas in the horizontal and upward cylinders. In order to ensure the normal operation of the cylinders, the gas in the cylinders needs to be discharged. [0003] Ordinary exhaust devices are generally exhaust screws, and the exhaust screws are installed in the preset exhaust holes on the oil supply pipe joint of the pressure cylinder. A stepped round hole whose inner diameter increases sequentia...
