Description
Technical field
The utility model relates to a kind of GIS high-voltage switch gear technical field, specifically a kind of calibration valve for GIS high-voltage switch gear.
Background technique
GIS high-voltage switch gear is to utilize the SF6 gas with excellent insulation performance as the combined electrical apparatus of insulation and arc-extinguishing medium.Owing to being filled with the SF6 gas of certain pressure in GIS high-tension switch gear, for equipment safety operation, need accurately monitor SF6 gas in real time with instrument and apparatus, no matter be that the SF6 gas in high-voltage electrical equipment is monitored or carried out the recovery of gas or supplement, go by high-tension apparatus unique one carry out in connecing, this interface claims again calibration valve.Traditional calibration valve inside is the valve seat of a three-port structure, complex structure, be difficult for assembling and use, especially in the time of adjustment instrument, must close fluid source and instrument could be pulled down and carry out adjustment, after adjustment is qualified, again instrument is installed and connected, and then monitor, therefore, the dismounting of instrument, adjustment have affected the normal operation of equipment, the working efficiency of the equipment of reduction.
Summary of the invention
The utility model provides the calibration valve of realizing instrument dismounting or adjustment under the prerequisite of a kind of not impact equipment operation in order to overcome above-mentioned defect.
The technical solution adopted in the utility model is: a kind of calibration valve for GIS high-voltage switch gear, comprise the valve seat of inside with Three way type passage, in three passages of valve seat, the outer end of passage one is provided with the jointing with self-sealing joint, the outer end of passage two is provided with the instrument connector that can be connected with instrument, passage three is communicated with high-tension switch gear air chamber, and passage one is along same axis setting with passage three, passage two is perpendicular to passage one and passage three, it is characterized in that: also comprise two ball valves and a gas-tpe fitting, gas-tpe fitting is arranged on the outer end of passage three, one of them ball valve claims left ball valve, left ball valve is arranged on passage one, the inner side of jointing, another ball valve claims right ball valve, right ball valve is arranged on passage three, the inner side of gas-tpe fitting, on the switch handle of two ball valves, be provided with Warning board.
The utility model will be provided with gas-tpe fitting on the passage of traditional threeway valve seat, facilitates adjustment valve to be communicated with equipment air chamber, and in valve seat, to be provided with two ball valves be left ball valve and right ball valve, closes left ball valve and right ball valve, and instrument can be conveniently installed; Then open right ball valve, left ball valve keeps closing, instrument and fluid source connection, and high-tension switch gear air chamber is communicated with passage two by pipeline and passage one, can real-time watch device pressure by instrument; In the time that needs are changed instrument, only need close right ball valve and just can; In the time that needs carry out adjustment to instrument, adjustment instrument is connected on jointing, then open left ball valve and keep right ball valve to open simultaneously, adjustment instrument is like this connected with equipment fluid source, realize adjusting function, adjustment instrument does not affect the operation of equipment, has improved the working efficiency of equipment.The utility model utilizes two ball valves to realize calibration valve path and opens and closes step by step, no matter carries out adjustment instrument or installation or disassembling, assembling and replacing instrument, only need to open or close corresponding ball valve just can, do not affect the normal operation of high-tension switch gear.
