Abstract
The utility model discloses a tool for fastening the valve core of a butterfly valve. The tool comprises a sleeve cylinder (1) and a force arm rod (2), wherein, a force arm installation hole (3) is radially formed at the one end of the sleeve cylinder (1), the force arm rod (2) penetrates the installation hole (3), and two symmetrical positioning teeth (4) are arranged on the cylinder wall at the other end of the sleeve cylinder (1). When in use, firstly, the seal cover of the valve core of the butterfly valve is opened; secondly, one end of the sleeve cylinder where the positioning teeth (4) are provided is inserted into the valve core of the butterfly valve, and the force arm rod (2) with an appropriate length is inserted into the installation hole (3) at the other end; and finally, the force arm rod (2) is rotated to the extent that the pressure thereof is appropriate. The fastening tool has the advantages of simple structure and convenient use, and can significantly improve the performance and shorten repair time in inspecting and repairing the butterfly valve and fastening the valve core, thereby increasing economic benefits for companies, reducing workload of workers and raising work efficiency.
Description
Technical field
The utility model relates to fastened tools, is specifically related to a kind of butterfly valve core fastened tools.
Background technology
As everyone knows, because butterfly valve is second-rate, or it is loosening that the spool clamping nut easily takes place after long-term the use, thereby cause the spool oil impregnate, at present, maintenance or during fastening spool method comparatively original, taste that not have specific purpose tool to be used for spool fastening, in addition, if fastening dynamics control is improper, the spool clamping nut is difficult for the loosening employing hammer that needs sometimes and strikes, and fragile spool reduces service life.
Summary of the invention
The purpose of this utility model is: a kind of butterfly valve core fastened tools is provided, and fastening by this fastened tools auxiliary spool, raising speed ensures the spool installation quality.
Technical solution of the present utility model is: this fastened tools comprises ferrule sleeve and arm bar, radially establishes the arm bar installing hole at an end of ferrule sleeve, and arm bar passes through installing hole.
In the butterfly valve core fastened tools of the present utility model, on the barrel of the other end of ferrule sleeve, establish the positioning tooth of two symmetries.
In the butterfly valve core fastened tools of the present utility model, the internal diameter of ferrule sleeve is slightly larger than the external diameter of butterfly valve core.
During use, at first open the butterfly valve core capping; An end that then ferrule sleeve is had fully positioning tooth inserts butterfly valve core, or an end of ferrule sleeve is enclosed within on the butterfly valve core the interspersed arm bar that is of convenient length in the installing hole of the other end; Last rotatory force armed lever is to convenient pressure.
The utility model is simple in structure, and is easy to use, can significantly improve repair quality when butterfly valve maintenance and fastening spool, shortens the repair time, thereby improves business economic benefit, the work of minimizing manpower, increases work efficiency.
