Four-way valve reversing and chamfering machining device

Abstract

The invention discloses a four-way valve reversing and chamfering machining device. The device comprises a base, a feeding table is welded to the top end of the base, a working frame is welded to the position, located at the top end of the base, of the side face of the feeding table, a motor is fixedly connected to the inner wall of the working frame, a pore plate is installed at the output end of the motor, a guide column is slidably connected to the inner wall of the pore plate, a guide block is welded to the top end of the guide column, and the inner wall of the guide block is slidably connected with a sliding rod fixedly connected with the inner wall of the working frame. According to the four-way valve reversing and chamfering machining device, through the arrangement of the sliding rod, in the working frame, the motor rotates to drive the pore plate to rotate, the longest distance from the sliding rod to the motor is equal to the length of the pore plate, the pore plate drives the guide block to move along the sliding rod through the guide column, the sliding rod is in the shape of a Chinese character 'ao', the guide block drives a limiting cylinder to move through a supporting arm, the sliding track of the limiting cylinder is the same as the shape of the sliding rod, and accurate control over the movement track of the limiting cylinder is achieved.

Description

technical field [0001] The invention relates to the technical field of four-way valves, in particular to a four-way valve reversing chamfering processing device. Background technique [0002] The four-way valve is a control valve with four oil ports. The four-way valve is an indispensable part of refrigeration equipment. Its working principle is that when the solenoid valve coil is in a power-off state, the pilot slide valve is driven by the compression spring on the right. Move to the left, the high-pressure gas enters the capillary and then enters the piston chamber at the right end. On the other hand, the gas in the piston chamber at the left end is discharged. Due to the pressure difference between the two ends of the piston, the piston and the main slide valve move to the left, so that the exhaust pipe communicates with the outdoor unit. The other two connecting pipes are connected to form a refrigeration cycle. When the solenoid valve coil is in the energized state, th...
