Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] like Figure 1 to Figure 3 As shown, a threaded assembly tool suitable for valves between the valve body and the valve cover includes a base 1, a column 2 and a beam box 3, and the base 1 is provided with a workbench and a beam for fixing the valve body. An assembly assembly that rotates synchronously with the valve cover and can move up and down is arranged on the box body 3; the assembly assembly includes assembly linkage shaft device 6, assembly linkage shaft feeding device 5 and assembly linkage shaft lifting device 4.

[0019] Wherein the assembly linkage shaft device 6 comprises a guide column barrel 65 with a tooth rack arranged on the outer wall, an assembl...

Abstract

The invention provides a tool suitable for threaded assembly between a valve body and a valve deck of a valve. The tool comprises a base, a stand column and a beam box body. A working table used for fixing the valve body is arranged on the base. An assembling assembly is arranged on the beam box body and comprises an assembling linkage shaft device. The assembling linkage shaft device comprises a guide column, an assembling linkage shaft, a power source and a threaded assembly fixing end, wherein a rack is arranged on the outer wall of the guide column, the assembling linkage shaft is arranged on the inner wall of the guide column, the power source is arranged on the inner wall of the guide column, and the threaded assembly fixing end is arranged at one end of the assembling linkage shaft. A concentric chuck used for fixing the valve body is arranged on the working table. At least one first positioning piece used for preventing the valve from rotating on the concentric chuck is arranged on the concentric chuck. The first positioning pieces are matched with connecting holes corresponding to the flange end faces of the valve. The tool aims at solving the problems that due to the fact that assembly in the existing assembling process is not precise, valve leakage is caused, efficiency is low, and people are easily hurt.

Description

technical field [0001] The invention relates to a thread assembly tool, in particular to a tool used for thread assembly between a valve body and a valve cover of a valve. Background technique [0002] The threaded assembly of the valve mainly refers to the threaded assembly between the valve body and the valve cover. The valve body also includes a ball and an elastic gasket. At the same time of cooperation, it is also necessary to apply axial pressure to ensure the perfect sealing between the valve cover and the valve body. [0003] In the prior art, manual thread assembly is generally used, and threaded assembly fixtures are generally used. The threaded assembly fixture includes its body and assembly handle. When assembling, the threaded assembly fixture and the end of the valve cover are first coaxial. Connection, generally for different bonnet structures, the way of coaxial connection is also different, such as the end surface of the bonnet is provided with holes or mat...
