The invention discloses a valve pressure test machine, which comprises a bottom plate, an air pump box, an electric push rod, a valve, a lifting device, a first buffer mechanism and a protection box, and is characterized in that the electric push rod is installed on a top plate of the bottom plate, and the output end of the electric push rod is provided with a ventilation disc; the lifting device comprises a transmission box, a motor, a gear and rack transmission mechanism, a connecting plate and a guide rod, the gear and rack transmission mechanism is installed at the output end of the motor, and the first buffering mechanism comprises an upper connecting plate, a connecting rod mechanism, a buffering part and a lower connecting plate. The valve comprises a valve body, an upper connecting flange, a lower connecting flange and a left connecting flange. According to the valve pressure test machine provided by the invention, the pressure test can be performed on the valve in the protection box through the lifting device, the valve pressure test risk can be greatly reduced, the safety of an operator and equipment is effectively protected, the operation is easy, and convenience is provided for the valve pressure test.
Description
technical field [0001] The invention relates to the field of valve channel pressure testing equipment, in particular to a valve pressure testing machine. Background technique [0002] With the continuous development of valve technology and the continuous expansion of valve application fields, the corresponding valve standards are becoming more and more indispensable. Products in the valve industry have entered a period of innovation. Not only product categories need to be updated, but internal management of enterprises also needs to deepen reforms according to industry standards. For the valves in operation, all valve parts should be complete and intact. The bolts on the flange and the bracket are indispensable, and the threads should be intact and no loosening is allowed. If the fastening nut on the handwheel is found to be loose, it should be tightened in time to avoid abrasion of the joint or loss of the handwheel and nameplate. If the handwheel is lost, it is not allo...
