Valve element disassembling device and disassembling method

Abstract

The invention discloses a valve element disassembling device and a valve element disassembling method. The valve element disassembling device comprises a locking sleeve, an adapter sleeve and a handle, wherein the locking sleeve is provided with a clamping part and a connecting rod, the clamping part comprises at least two clamping arms which are oppositely arranged, and the clamping arms form a conical cavity capable of containing a valve element; in the circumferential direction of the conical cavity, a gap is formed between every two adjacent clamping arms, and an external thread is arranged on the outer wall of the clamping part; the adapter sleeve can be connected to the outer side of the locking sleeve in a sleeving mode, the adapter sleeve is a hollow cylinder, an internal thread matched with the external thread of the locking sleeve is arranged on the inner wall of the adapter sleeve, the adapter sleeve is located at a preset position of the clamping part, and the conical cavity can clamp the valve element; and the handle is arranged on the connecting rod. When the adapter sleeve moves, the gap between every two adjacent clamping arms is gradually reduced until the conicalcavity clamps the valve element, and then the valve element is pulled out through the handle. The contact area between the conical cavity and the valve element is large, the contact surfaces between the clamping arms and the valve element are not prone to slipping, the disassembling time of the valve element is shortened, and the disassembling efficiency is improved.

Description

technical field [0001] The invention relates to the field of removal tools, in particular to a valve core remover and a removal method. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. The spool and valve body are important parts of the valve. After a period of operation, the spool hardens due to the accumulation of lubricating oil and grease, and the precision of the spool and the valve body is high, so the spool is often stuck in the valve body and cannot work. , affecting the service life of the equipment. Therefore, the spool needs to be disassembled and cleaned regularly. [0003] At present, the spools of some valves are all located in the valve block, resulting in less space for disassembly of the spools. At present, the common disassembly method of this type of spoo...

Problems solved by technology

However, due to the small effective contact area between the tip of the needle-nose pliers and the valve core, it is easy to slip between the tip of the needle-nose pliers and the contact surface of the valve core during the drawing process, and the valve core is not easy to be pulled out, resulting in disassembly of the valve core. It is necessary to use needle-nose pliers to pull the valve core multiple times, which takes a long time and the disassembly efficiency is low
