Device used for machining safety valve element

Abstract

The invention discloses a device for processing the valve core of a safety valve, which comprises a base, a support shaft, a processing table, a driving mechanism, a plurality of clamping parts, a grinding part, and a limit rod; the support shaft is vertically rotated and installed on the base The processing table is installed on the support shaft; the driving mechanism is used to drive the support shaft to rotate; multiple clamping parts are evenly distributed around the support shaft, and the clamping parts include a bottom plate, a first clamping plate, a second clamping plate, a rotating The shaft, the first connecting piece, the second connecting piece, and the bottom plate are installed on the processing table, and guide rails are arranged on the bottom plate; the first clamping plate and the second clamping plate are distributed in sequence along the length direction of the guide rail, and the first clamping plate On the base plate; the second clamping plate is slidingly connected with the guide rail; the rotating shaft is vertically rotated and installed on the base plate; one end of the first connecting piece is hinged with the second clamping plate, and the other end of the first connecting piece is connected with the second connecting piece hinged.

Description

technical field [0001] The invention relates to the technical field of safety valve processing, in particular to a device for processing a safety valve core. Background technique [0002] The safety valve is a valve for safety protection. Its opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises and exceeds the specified value, it will automatically open. The medium pressure in the pipeline or equipment exceeds the specified value. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines, to control the pressure not to exceed the specified value, and play an important role in protecting personal safety and equipment operation. [0003] The surface of the safety valve spool is not smooth, and the spool needs to be polished. The current method is to position the spool with a pressing device, and then use a grinding device to polish it. However, ...

Problems solved by technology

[0003] The surface of the safety valve spool is not smooth, and the spool needs to be polished. The current method is to position the spool with a pressing device, and then use a grinding device to polish it. However, this method requires separate inspection of each valve. Grinding the core, disassembled after grinding, and then grinding another valve core, this method is not efficient, and the existing device has a complex structure and is inconvenient to use, and needs further improvement
