Problems solved by technology

At present, the hard-sealed copper pad of the check valve is prone to vibrating knife marks after processing in the workshop, and the fineness often does not meet the standard, resulting in micro-leakage of the medium when the hard-sealed copper pad of the check valve is sealed, which cannot meet the needs of users.
At present, manual electric grinders are mostly used to grind the hard-sealed copper pads installed in the check valve body, which is not easy to operate, and the surface grinding is uneven

Abstract

The invention discloses a grinding machine for hard seal copper gaskets of check valves. The grinding machine comprises a base, a door-shaped frame, a speed reducer, a hard seal copper gasket grinding device, a lifting device of the hard seal copper gasket grinding device, a limiting device of the hard seal copper gasket grinding device, a check valve body fixing device and an electrical and pneumatic control device. The door-shaped frame is formed by vertical columns and a crossbeam, the hard seal copper gasket grinding device is mounted below the crossbeam of the door-shaped frame, and the check valve body fixing device is mounted on a platform of the base. The grinding machine for the hard seal copper gaskets of the check valves has the advantages that automatic grinding of the hard seal copper gaskets of the check valves is realized, hard seal copper gasket grinding fineness is improved, requirements of hard seal copper gasket grinding process are met, slight leakage of media in use of the hard seal copper gaskets for sealing is prevented, and operation efficiency in grinding of the hard seal copper gaskets is improved.

Description

technical field [0001] The invention belongs to a mechanical grinding device, in particular to a check valve hard-sealed copper pad grinding machine. Background technique [0002] Check valve, also known as one-way valve or check valve, is used to prevent the medium in the pipeline from flowing backward. The hard-sealed copper gasket of the check valve refers to the hard-sealed copper gasket installed in the check valve body (see the appendix of the manual). image 3 And the content recorded in the second last line on page 2-the first line on page 3 of the original manual: "Start the reducer, the grinding rod installed on the output shaft of the reducer drives the grinding head installed on the top to rotate, and the hard seal in the check valve body The copper pad is ground, and when the set time required by the grinding process is reached, the grinding stops." The technology that the hard-sealed copper gasket is installed in the check valve body is the prior art. At pres...
