  • Patent number: 8205639
    Abstract: Disclosed is a valve sealant fitting of high quality, which not only ensures rapid and easy injection of a sealant but also maximizes an effect of preventing a leakage. That is, the present invention provides a valve sealant fitting, which comprises, sequentially assembles and couples: a sealant body 10 having an insert coupling groove 12 with a sealing O-ring 12a mounted on an inner wall of the body, a sealant exit port 13 with a small diameter and a sloped injection port at a lower end of the body, and an exit port side ball 14 mounted at a bottom of the exit port 13; an insert 20 having an intermediate sealant movement path 21 for guiding the sealant to be injected toward an inner center of the insert and having a sealed port 22 and a coil spring 23 interposed at a lower end of the insert; and an upper end cap 30 having a sealant injection port 31 with a small diameter mounted on an upper end of the insert 20 and having an injection port side ball 32 mounted below the injection port 31.

  • Publication number: 20090217990
    Abstract: Disclosed are a valve sealant fitting and a method of manufacturing the same, which not only allows a sealant to be rapidly and easily injected but also prevents a leakage, which result in a more facilitated manufacturing process with reduced costs and a superior mechanical quality. In particular, the sealant fitting includes: a spring coupling unit 150 having an internal screw thread 140 for coupling unit assembly below the ball installation groove 103 of the sealant body 100, the internal screw thread 140 having a hexagonal groove 151 for preventing a downward separation of the coil spring 130, allowing a fluid to flow and facilitating fastening and releasing of the screw, and having an external screw thread 152 at an outer circumference of the spring coupling unit; and outer sealing O-rings 160 and 160-1 disposed in O-ring installation grooves 161 formed on respective upper and lower positions of the valve coupling taper screw part 101-1 formed on the outer lower side of the sealant body 100.
