Description
Technical field
The utility model relates to SF6 gas sampling technique, specifically the micro-water of a kind of GIS device SF6 gas, composition, purity test threeway sample valve.
Background technology
SF6 gas is often used as the insulating medium of GIS device.Therefore, when testing GIS device, need to sample the SF6 gas in GIS device, and the SF6 gas sampled out is drained to micro-water tester, composition test instrument, purity test instrument respectively, then test three indexs of SF6 gas respectively by micro-water tester, composition test instrument, purity test instrument: micro-water, composition, purity.Under prior art conditions, SF6 stopple coupon is generally adopted to sample the SF6 gas in GIS device.Practice shows, existing SF6 stopple coupon limit due to self structure, there is the problem that sample time is long, sampling efficiency is low.Specifically, existing SF6 stopple coupon is single pipe structure, causes it cannot to shunt the SF6 gas sampled out.Therefore, in order to test three indexs of SF6 gas, existing SF6 stopple coupon needs to carry out three sub-samplings to SF6 gas successively, causes that sample time is long, sampling efficiency is low thus.Based on this, be necessary to invent a kind of brand-new SF6 gas sample tube, to solve the problem that existing SF6 gas sample tube sample time is long, sampling efficiency is low.
Summary of the invention
The utility model, in order to solve the problem that existing SF6 gas sample tube sample time is long, sampling efficiency is low, provides the micro-water of a kind of GIS device SF6 gas, composition, purity test threeway sample valve.
The utility model adopts following technical scheme to realize: the micro-water of GIS device SF6 gas, composition, purity test threeway sample valve, comprises four-way piece, main sampling pipe, SF6 gas sample connecting pipe, micro-water sampling connecting pipe, composition sampling connecting pipe, purity sampling connecting pipe, micro-water sampling retaining valve, composition sampling retaining valve, purity sampling retaining valve; Wherein, one end ferrule of main sampling pipe is socketed on first mouth of pipe outer wall of four-way piece; One end ferrule of SF6 gas sample connecting pipe is socketed on the other end mouth of pipe outer wall of main sampling pipe; One end ferrule of micro-water sampling connecting pipe is socketed on second mouth of pipe outer wall of four-way piece; One end ferrule of composition sampling connecting pipe is socketed on the 3rd mouth of pipe outer wall of four-way piece; One end ferrule of purity sampling connecting pipe is socketed on the 4th mouth of pipe outer wall of four-way piece; Micro-water sampling retaining valve is installed on second mouth of pipe of four-way piece; Composition sampling retaining valve is installed on the 3rd mouth of pipe of four-way piece; Purity sampling retaining valve is installed on the 4th mouth of pipe of four-way piece; The import of the import of micro-water sampling retaining valve, the import of composition sampling retaining valve, purity sampling retaining valve is all communicated with first mouth of pipe of four-way piece.
During use, the other end mouth of pipe of SF6 gas sample connecting pipe is connected with the air chamber of GIS device, the other end mouth of pipe of micro-water sampling connecting pipe is connected with micro-water tester, other end mouth of pipe composition being sampled connecting pipe is connected with composition test instrument, and other end mouth of pipe purity being sampled connecting pipe is connected with purity test instrument.When testing GIS device, open micro-water sampling retaining valve, composition sampling retaining valve, purity sampling retaining valve simultaneously.Now, SF6 gas in GIS device flow to four-way piece by SF6 gas sample connecting pipe, main sampling pipe successively, and being split into three tunnels by second mouth of pipe of four-way piece, the 3rd mouth of pipe of four-way piece, the 4th mouth of pipe of four-way piece: the first via flow to micro-water tester by micro-water sampling connecting pipe, second tunnel flow to composition test instrument by composition sampling connecting pipe, and the 3rd tunnel flow to purity test instrument by purity sampling connecting pipe.Then, three indexs of SF6 gas are tested respectively by micro-water tester, composition test instrument, purity test instrument: micro-water, composition, purity.Based on said process, compared with existing SF6 gas sample tube, the micro-water of GIS device SF6 gas described in the utility model, composition, purity test threeway sample valve are by adopting brand new, the SF6 gas achieved sampling out is shunted, and thus achieves and is drained to micro-water tester, composition test instrument, purity test instrument respectively by disposable for the SF6 gas sampled out.Therefore, the micro-water of GIS device SF6 gas described in the utility model, composition, purity test threeway sample valve only need carry out primary sample to SF6 gas, just can test three indexs of SF6 gas, effectively shorten sample time thus, effectively improve sampling efficiency.
The utility model efficiently solves the problem that existing SF6 gas sample tube sample time is long, sampling efficiency is low, is applicable to GIS device test.
