Technical Field

The utility model relates to a valve gap structure of fixed ball valve, especially a can promptly annotate ball valve gap structure of fat on line.

Background

As is known, a valve is an important component of fluid in a petroleum, chemical and natural gas pipeline conveying system, and with the high-speed development of modern industry, a ball valve occupies a considerable share of the market due to the advantages of quick opening and closing, small flow resistance and high bearing pressure, and the three-piece side-mounted fixed ball valve is widely applied to modern industrial pipelines.

Disclosure of Invention

In order to overcome the not enough of prior art existence, the utility model provides a can promptly annotate ball valve gap structure of fat on line, including the valve gap, annotate the fat groove, sealed fat injection valve, check valve, annotate fat passageway, valve body, seal gasket, O type circle.

The utility model provides a technical scheme that prior art problem adopted is seted up perpendicularly in the valve gap and annotated the fat groove, annotate the fat inslot and process there is the internal thread, annotates the fat inslot and be equipped with sealed fat filling valve, sealed fat filling valve annotates the fat inslot through screw mode screw in, the grease inlet of sealed fat filling valve lower extreme fixed connection check valve, the play fat mouth of check valve links to each other with the one end of annotating the fat passageway, annotate the fat passageway and be L shape setting, annotate sealed face looks butt between the other end of fat passageway and valve body, the valve gap, be equipped with seal gasket on the vertical direction between valve gap and the valve body, be equipped with O type circle on the horizontal direction between valve gap and the valve body.

The utility model has the advantages that: through having seted up in the valve gap and annotating the fat groove, annotate the fat passageway, and at annotating the sealed fat filling valve of fat inslot setting, the check valve, work as the valve body, the damaged or ageing production of O type circle of valve gap junction leaks, the valve body, the fire prevention gasket of valve gap junction is leaking appearing under the pipeline stress influence, to pouring into sealed fat in the sealed fat filling valve, sealed fat arrives through the check valve and annotates the fat passageway and be full of whole notes fat passageway, can prevent temporarily that the medium from continuing to leak away between valve body and the valve gap, salvage and strive for more time for pipeline installation parking valve, also can reduce because of the valve leaks the environmental pollution who causes outward.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure, the valve comprises a valve cover 1, a valve cover 2, a grease injection groove 3, a sealing grease injection valve 4, a check valve 5, a grease injection channel 6, a valve body 7, a sealing gasket 8 and an O-shaped ring.

Detailed Description

It is right to next combine attached drawing and embodiment the utility model discloses make further detailed explanation, a can online urgent grease injection's ball valve gap structure, including valve gap 1, annotate fat groove 2, sealed fat injection valve 3, check valve 4, annotate fat passageway 5, valve body 6, seal gasket 7, O type circle 8, notes fat groove 2 has been seted up perpendicularly in the valve gap 1, it has the internal thread to annotate to process in the fat groove 2, annotate and be equipped with sealed fat injection valve 3 in the fat groove 2, sealed fat injection valve 3 is through the screw thread mode screw in annotate fat groove 2 in, the grease inlet of sealed fat injection valve 3 lower extreme fixed connection check valve 4, check valve 4 plays to annotate the fat reliably, avoids sealed fat backward flow, the play fat mouth of check valve 4 links to each other with the one end of annotating fat passageway 5, it is L shape setting to annotate fat passageway 5, annotate the other end of fat passageway 5 and valve body 6, the butt joint between the valve gap 1, be equipped with seal gasket 7 on the vertical direction between valve gap 1 and the valve gap 6, be equipped with the valve gap 8 on the valve gap 6 and the valve gap 6 between valve body 6, the valve gap 6 is connected when valve body 6, the valve body 6 is connected, the sealed fat leakage pipeline leakage of sealed fat leakage that the pipeline that the sealed fat leakage can be got also.

The utility model discloses an it annotates fat groove 2 to establish in valve gap 1, annotate fat passageway 5, and set up sealed fat filling valve 3 in annotating fat groove 2, check valve 4, work as valve body 6, the damaged or ageing production of O type circle 8 of valve gap 1 junction leaks, valve body 6, seal gasket 7 of valve gap 1 junction leaks appearing under the pipeline stress influence, to pouring into sealed fat in the sealed fat filling valve 3, sealed fat reachs through check valve 4 and annotates fat passageway 5 and be full of whole notes fat passageway 5, can prevent temporarily that the medium from continuing to leak away from between valve body 6 and valve gap 1, salvage for pipeline device parking valve and strive for more time, also can reduce because of the valve leaks the environmental pollution who causes outward.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
