Abstract

The invention discloses a switching valve airtightness detection device, and belongs to the technical field of mechanical equipment. The device mainly comprises a bearing plate, a pressurizing mechanism, a bearing mechanism and a mixed detection mechanism, wherein a first driver is arranged on the bearing plate; the pressurizing mechanism comprises a sliding table plate slidably connected with thebearing plate and a pressurizing pipe arranged on the sliding table plate; the bearing mechanism comprises a bearing table, a fixed disc, a driven gear arranged on the fixed disc, a second driver installed on the bearing table, a driving gear arranged at the output end of the second driver and a fixed shaft; a first stepped hole is formed in the position, corresponding to a valve seat of a switching valve, of the fixed disc; a positioning block is arranged at the end, stretching into the fixed disc, of the fixed shaft; and the mixed detection mechanism comprises a rack installed on the bearing table, a sliding block, a connecting air pipe arranged on the sliding block, a liquid pipe arranged on the sliding block and a third driver installed on the sliding block. According to the switchingvalve airtightness detection device, airtightness detection can be efficiently and effectively carried out on the switching valve.

Description

Technical field[0001]The invention relates to the technical field of mechanical equipment, in particular to a switching valve air tightness detection device.Background technique[0002]The switching valve uses the relative rotation of the rotor to change the connecting flow path, refer toFigure 7 As shown, the switching valve 600 includes a valve head 610, a valve seat 620 provided at one end of the valve head, a rotor 630 rotatable relative to the valve head 610, and a rotating shaft 640 housed in the valve seat 620 and fixed to the rotor 630. The valve head 610 A common interface 611 and a plurality of reversing interfaces 612 are provided on the upper opening, and a groove 631 is opened on the rotor 630 to rotate the rotor 630 relative to each other, so that the groove 631 communicates with the target reversing interface 612 to realize the switching of fluid flow channels. Due to the large number of reversing ports 612 of this switching valve, it is difficult for the existing air t...
