Abstract
The invention relates to a liquid charging valve mandril, which comprises a rod body, an upper limit connecting sleeve and a lower limit fixing sleeve and is characterized in that: the upper part and the lower part of the rod body are respectively provided with an upper snap spring groove and a lower snap spring groove; an upper snap spring and a lower snap spring are respectively embedded in the upper snap spring groove and the lower snap spring groove; the upper limit connecting sleeve is arranged on the upper snap spring through a stopper screw; the lower limit fixing sleeve is arranged on the lower snap spring in a crimping way. Because the upper limit connecting sleeve and the lower limit fixing sleeve are both fixed on the rod body through the snap springs, and the sizes of the upper snap spring groove and the lower snap spring groove are greatly reduced compared with the size of a snap ring groove, the rod body of the mandril is prevented from breaking, and the service life of the mandril is prolonged.
Description
Technical field
The present invention relates to a kind of liquid-filling valve, particularly a kind of liquid-filling valve push rod of not easy-rupturing.
Background technique
Liquid-filling valve is a kind of Pilot operated check valve, a direction fluid stopping, and another direction free flow has reliable sealing performance, in metal forming machinery, is widely used.
The push rod of liquid-filling valve is provided with a upper limit and a lower limit, and upper limit is used for fixing the Returnning spring on the push rod, and lower limit is used for fixing the spool of liquid-filling valve.Traditional liquid-filling valve push rod structure is as shown in Figure 1, and the upper limit of push rod 1 adopts upper limit connecting sleeve 7 to be threaded in push rod top, and upper limit connecting sleeve 7 sidewalls are established the fastening screw 8 that props up push rod 1; Lower limit adopts push rod 1 bottom to open annular groove, and the embedded semicircle snap ring 9 of annular groove is provided with fixed cover 10 and locking cap 11 respectively at the upper and lower of snap ring 9, is fixed on snap ring 9 places by fixed cover 10 and locking cap 11 screw-thread fit.The shortcoming of this kind structure is: the size of annular groove is relatively large, makes the push rod easy-rupturing at this place, and influence is used normally, safeguards very inconvenient; The connecting sleeve of upper limit is threaded with push rod, processing, inconvenient installation.
Summary of the invention
The technical problem that the present invention will solve provides a kind of liquid-filling valve push rod of not easy-rupturing.
For solving the problems of the technologies described above; Technological scheme of the present invention is: a kind of liquid-filling valve push rod; Comprise the body of rod, upper limit connecting sleeve and lower limit fixed cover; Its innovative point is: said body of rod upper and lower is opened jump ring groove and lower circlip groove respectively, and said going up in jump ring groove and the lower circlip groove is embedded with jump ring and lower circlip respectively; Said upper limit connecting sleeve is installed on the jump ring through the fastening screw, and said lower limit fixed cover is installed on the lower circlip through crimping.
The invention has the advantages that: upper limit connecting sleeve and lower limit fixed cover all are fixed on the body of rod through jump ring, and the size of upper and lower jump ring groove is compared annular groove and reduced greatly, have avoided the fracture of the push rod body of rod, have improved working life.
Description of drawings
Fig. 1 is for adopting the liquid-filling valve structural representation of traditional push rod structure.
Fig. 2 is liquid-filling valve push rod structure schematic representation among the present invention.
Fig. 3 is installed in structural representation on the liquid-filling valve push rod for upper limit connecting sleeve among the present invention and lower limit fixed cover.
Embodiment
Like Fig. 2, shown in 3, comprise the body of rod 1, last jump ring groove 2, lower circlip groove 3, go up jump ring 4, lower circlip 5, lower limit fixed cover 6, upper limit connecting sleeve 7 and fastening screw 8.
The upper and lower of the above-mentioned body of rod 1 has jump ring groove 2 and lower circlip groove 3, in last jump ring groove 2 and lower circlip groove 3, is embedded with jump ring 4 and lower circlip 5 respectively.
After lower limit fixed cover 6 is installed on the lower circlip 5 through frock, through being fixed on the lower circlip 5 after the upper end extruding closing in of crimping with lower limit fixed cover 6.Upper limit connecting sleeve 7 is fixed on the jump ring 4 through fastening screw 8 after being installed on the jump ring 4.
Claims (1)
1. a liquid-filling valve push rod comprises the body of rod, upper limit connecting sleeve and lower limit fixed cover, it is characterized in that: said body of rod upper and lower is opened jump ring groove and lower circlip groove respectively, and said going up in jump ring groove and the lower circlip groove is embedded with jump ring and lower circlip respectively; Said upper limit connecting sleeve is installed on the jump ring through the fastening screw, and said lower limit fixed cover is installed on the lower circlip through crimping.
