The utility model relates to a multi -functional packing gland of plunger pump. Mainly solved the plunger pump leakage liquid of existence among the prior art and can follow the blowout of plunger axis and the problem of polluted environment, corruption packing box screw thread when the packing pine. Its characterized in that: packing gland (1) tip open and to have the counter bore, it has a plurality of guiding gutter (5) to open on the terminal surface of counter bore, and guiding gutter (5) communicate with each other with packing gland (1) surface, the counter bore built -in have manger plate sealing washer (4), manger plate sealing washer (4) outer deployment has sealing washer clamp plate (2), and sealing washer clamp plate (2) are fixed on packing gland (1) through screw (3). This multi -functional packing gland of plunger pump can prevent packing leakage liquid along plunger axis blowout, and liquid is not not beyond the scope of spouting, and the polluted environment is avoided to incorruptible packing box screw thread.
