Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tools, in particular to a special disassembly tool for a servo valve. Background Art

[0002] In the Danfoss ICS25 servo valve, the two sealing rings on the function module are embedded in the inner groove of the valve body, and the function module is flush with the valve body end face. After long-term use, oil molecules and impurities in the ammonia gas can reduce the gap between the function module and the valve body, causing a tight engagement and making it difficult to remove the function module from the valve body.

[0003] The existing method for removing a functional module involves screwing a bolt into the threaded hole at the top of the module and using one or two flat-blade screwdrivers to pry the bolt, thereby driving the module out of the valve body. During the removal process, the flat-blade screwdriver must use the end face of the valve body as a fulcrum to pry the bolt. If the suction force between the functional module and the valve body is large, the remover may use excessive force or perform improper operation, causing damage to the valve body end face. Since the module is generally welded to an outdoor suspended pipe, using this method can cause the module to fall to the ground if excessive force or improper operation is used, thereby damaging the module and putting the remover in danger.

[0004] Therefore, in view of the deficiencies in the prior art, a special disassembly tool for a servo valve is provided. Utility Model Content

[0010] The first fixing member abuts against the end surface of the functional module, and the first fixing member is connected to the connecting rod;

[0011] The base is located on the end surface of the valve body and supports the substrate.

[0012] As a further improvement of the technical solution of the present invention, a protective member is further included. The protective member is located between the first fixing member and the base, and the protective member is sleeved on the connecting rod.

[0013] As a further improvement of the technical solution of the utility model, a wrench is also included, and the wrench is adapted to the adjusting member.

[0014] As a further improvement of the technical solution of the present invention, it also includes a second fixing member, which is fixedly connected to the top of the connecting rod.
