Description
Technical Field
The invention belongs to the field of mechanical assembly, and particularly relates to a graphite ring mounting tool for a valve cavity of a safety valve pilot valve of a nuclear power station.
Background
The nuclear power station SEBI IM safety valve pilot valve structure is complicated, and the maintenance is difficult, and the inside design of pilot valve chamber has the graphite sealing ring, and this graphite sealing ring need be changed again when the valve disintegrates the maintenance, when installing new graphite ring, because the position of the inside installation graphite ring of pilot valve chamber is darker, general method is to utilize the manual work to press after putting into the valve body with the graphite ring inside, relies on the sensation to install, and the problem is that the installation is difficult, is difficult to install in place to damage the graphite ring easily.
Therefore, a special device needs to be designed for installing the graphite ring of the valve cavity of the SEBI IM safety valve pilot valve in the nuclear power station, and the problem that the graphite ring of the valve cavity of the SEBI IM safety valve pilot valve in the nuclear power station is difficult to install is solved.
Disclosure of Invention
The invention aims to provide a graphite ring installation tool for a nuclear power station SEBI IM safety valve pilot valve cavity, which is used for installing a nuclear power station safety valve pilot valve cavity graphite ring and solves the problem that the nuclear power station SEBI IM safety valve pilot valve cavity graphite ring is difficult to install.
The technical scheme of the invention is as follows:
a graphite ring mounting tool for a valve cavity of a safety valve pilot valve of a nuclear power station comprises an inner guide rod, an outer mounting sleeve and a graphite ring; the outer mounting sleeve is hollow, the inner side of the inner guide rod is sleeved with the outer mounting sleeve, and the graphite ring is arranged at one end of the outer mounting sleeve.
The diameter of the inner guide rod is slightly smaller than the inner diameter of the graphite ring.
The inner diameter and the outer diameter of the outer mounting sleeve are respectively consistent with the inner diameter and the outer diameter of the graphite ring.
The invention has the beneficial effects that:
[1] the graphite ring mounting tool for the valve cavity of the SEBI IM safety valve pilot valve of the nuclear power station is simple in structure and convenient to use;
[2] the method can effectively solve the problem of difficulty in installing the graphite ring of the valve cavity of the SEBI IM safety valve pilot valve of the nuclear power station, saves time and labor, and improves the installation quality of the graphite ring of the valve cavity of the SEBI IM safety valve pilot valve.
Drawings
FIG. 1 is a structural diagram of a graphite ring mounting tool for a valve cavity of a safety valve pilot valve of a nuclear power station, according to the invention;
fig. 2 is a sectional view of a graphite ring mounting tool for a valve cavity of a safety valve pilot valve of a nuclear power station.
Detailed Description
The invention will be further described with reference to the following figures and examples:
a graphite ring mounting tool for a valve cavity of a safety valve pilot valve of a nuclear power station comprises an inner guide rod 1, an outer mounting sleeve 2 and a graphite ring 3; the outer mounting sleeve is hollow, the outer mounting sleeve 2 is sleeved on the inner side of the inner guide rod 1, and the graphite ring 3 is arranged at one end of the outer mounting sleeve 2.
The diameter of the inner guide rod 1 is slightly smaller than the inner diameter of the graphite ring 3.
The inner diameter and the outer diameter of the outer mounting sleeve 2 are respectively consistent with the inner diameter and the outer diameter of the graphite ring 3.
When the graphite ring installation tool for the valve cavity of the safety valve pilot valve of the nuclear power station is used for installing the graphite ring of the valve cavity of the SEBI IM safety valve of the nuclear power station, the tool is assembled according to a drawing, a new graphite ring which needs to be installed in the valve cavity of the safety valve pilot valve of the nuclear power station is installed on the tool according to the drawing 1, then the whole tool is placed into the valve cavity of the SEBI IM safety valve of the nuclear power station, the tool 1 is used for guiding the bottom of an inner guide rod, the graphite ring reaches the installation position, an outer installation sleeve 2 is pressed, the inner guide rod 1 is upwards extracted, the inner guide rod 1 is lifted to a position higher than the graphite ring, the outer installation sleeve 2 is lifted upwards, the tool is separated from the graphite ring, then the tool is lifted integrally, and the installation of the graphite ring of the valve cavity of the.
The present invention has been described in detail with reference to the drawings and examples, but the present invention is not limited to the examples, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. The prior art can be used for the content which is not described in detail in the present invention.
