Hydraulic press inside installation hydraulic packing piston do not have double-layer seal effect, sealing effectiveness is not very when in use
Ideal, replacing not easy to remove, usage time is short, and abrasion when in use causes economic waste with regard to needing what is more renewed.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of sealing for inside hydraulic press
Piston.
The utility model is achieved through the following technical solutions above-mentioned purpose, and a kind of sealing for inside hydraulic press is lived
Plug, a conical seat include for the sealing piston inside hydraulic press, be provided with the outside of described conical seat on one diaphragm seal with
One lower sealing piece, the bottom of described conical seat are provided with a catch bar, and described catch bar surface is provided with two bolts, and
Described conical seat top is provided with chassis, and a gland is provided with above described chassis, pacifies on the outside of described gland
Equipped with retainer ring, and a pin-and-hole is provided with the middle part of described gland, and an intermediate pin is installed inside described pin-and-hole.
Preferably, in order that conical seat is easily installed, conical structure is arranged to below described conical seat.
Preferably, in order that catch bar and bolt connection are convenient, described catch bar surface is provided with for fixing bolt
Screw thread.
Preferably, in order that retainer ring and gland can be installed directly, described retainer ring internal diameter and described
Gland external diameter size matches.
The beneficial effects of the utility model are：The sealing piston has Packed effect, using upper sealing piston and under it is close
Envelope piston is sealed, and the sealing effectiveness of double sealing piston is more perfect, and leakage is not susceptible to during use, enables to
The operating efficiency of hydraulic press is obviously improved, and catch bar surface is provided with screw thread, by screw thread can and bolt connection, it is convenient to close
Envelope piston integrally carries out disassembly and installation, connects compact between structure, and service life is long, and operating efficiency is high.Catch bar can rise
To stable impetus so that the pressure rise inside hydraulic press, reach the effect of work.
