Abstract:
1. A system for installing a sealant into a stuffing box of an industrial valve, wherein the system comprises: a. a first volatile organic compound injection valve for threadably securing to the stuffing box of the industrial valve wherein the first volatile organic compound injection valve has an injection port bore; b. a seal means disposed around the first volatile organic compound injection valve; c. a removable plug for sealingly engaging one end of the injection port bore; d. a rotatable shut off pin in the first volatile organic compound injection valve intersecting the injection port bore for regulating flow through the injection port bore; e. a high pressure packing gland in fluid communication with the first volatile organic compound injection valve, wherein the high pressure packing gland comprises: f. a rotatable packing gland shut off pin positioned to intersect the packing gland bore to regulate the sealant flowing through the packing gland bore or to stop the sealant from flowing through the packing gland bore; g. a pair of first seals, wherein one first seal of the pair of first seals is disposed on one side of the rotatable packing gland shut off pin and another first seal of the pair of first seals is disposed on the other side of the rotatable packing gland shut off pin, forming a secondary seal between the rotatable packing gland shut off pin and the packing gland body; h. a pair of second seals, wherein one second seal of the pair of second seals is disposed adjacent to one of the first seals of the pair of first seals and another second seal of the pair of second seals is disposed adjacent to the other first seal of the pair of first seals, each forming a tertiary seal between the rotatable packing gland shut off pin and the packing gland body; i. a pair of shut off pin retainers with one of the shut off pin retainers disposed on each side of one of the second seals of the pair of second seals forming a fourth seal between the rotatable packing gland shut off pin and the packing gland body; and j. packing material disposed in the threaded packing chamber; k. a compression nut for rotatably engaging the threaded packing chamber comprising: l. a second volatile organic compound injection valve threadably secured at a right angle to the packing gland bore at the threaded injection valve port for flowing the sealant into the packing gland bore; and m. a rod having a tapered end, a rod diameter and a rod stop, wherein the rod stop has a rod stop diameter, and further wherein the rod stop diameter is larger than the rod diameter, and the tapered end is adapted to penetrate the stuffing box of the industrial valve for injecting the sealant into the stuffing box.
