Pressure-proof sealing oil injector

Abstract

The invention discloses a pressure-proof sealing oil injector which comprises an oil outlet pipe nut, an oil outlet valve nut, a steel wire pressure-proof hose, a one-way oil outlet valve, an injection plug sleeve oil inlet, an injection plug sleeve, an injection plug rod, a connecting plate, a lever and handle, a hinge shaft, a lever bracket, a sealing oil cavity, an oil pressing piston, a compression spring, an oil injector housing, a threaded gland, a hinge pin and an electric heating device. The pressure-proof sealing oil injector is characterized in that the oil injector housing is internally provided with the injection plug sleeve; the injection plug sleeve is provided with the injection plug sleeve oil inlet; the injection plug rod is arranged in the middle of the injection plug sleeve; the one-way oil outlet valve is arranged at the front end of the injection plug sleeve, and is connected with the oil outlet valve nut of the steel wire pressure-proof hose; the connecting plate is arranged at the tail end of the injection plug rod, and is in hinge connection with the lever and handle; the lever bracket is arranged at the front end of the oil injector housing, and is hinged to the lever and handle by using the hinge shaft; the injection plug rod makes reciprocating motion; the sealing oil cavity is formed in a front area in the oil injector housing, and is used for storing sealing oil; the oil pressing piston, the compression spring and the threaded gland are arranged in a rear area in the oil injector housing; and the electric heating device is arranged on the outer surface of the oil injector housing for heating. Oil injection operation is carried out immediately after a power supply is disconnected, and the pressure-proof sealing oil injector is ideal.

Description

technical field [0001] A pressure-resistant sealing oil injector belongs to the technical field of powder processing machinery. Background technique [0002] The special sealing oil is used in the feeding machinery that requires pressure, such as powder processing machinery and pneumatic conveying equipment. Since the sealing oil is solid at normal temperature and pressure, when filling the feeding machinery with sealing oil, it must be The seal oil is preheated, and it is required to preheat the seal oil first, and then fill it up. At present, there is no such oil injector. Contents of the invention [0003] In order to solve the above problems, the invention discloses a pressure-resistant sealing oil oiler, which is used for filling the pressure-resistant sealing oil of powder processing machinery. [0004] In order to solve the above technical problems, the present invention discloses a pressure-resistant sealed oil injector, comprising: an oil outlet pipe nut, an oil ...
