Beneficial effect: compared with the prior art, the utility model discloses a this key components's of starter gas tightness detects and provides special testing tool. The detection method of starter gas tightness that it is perfect has simplified the condidence program.
Description
Technical field
The utility model belongs to pick-up unit, particularly relates to a kind of test device for air tightness for inert gas fire-fighting system gas storage cylinder container value starter.
Background technology
Gas extinguishing system is mainly used in the environment being unsuitable for arranging other fire extinguishing systems such as water fire-extinguishing system, such as computer room, important library files shop, mobile communication base station (room), UPS room, battery chamber, general diesel generator room etc.It is automatic that gas extinguishing system comprises mixed gas.Its feature: mixed gas fire extinguishing agent is the gas mixed according to a certain percentage by nitrogen, argon gas and carbon dioxide, these gases all naturally exist in atmospheric envelope, loss is not had to atmospheric ozone layer, also can not have an impact to " greenhouse effect " of the earth, and mixed gas is nontoxic, colourless, tasteless, non-corrosiveness, non-conductive, neither support burning, not producing with most of material again and react, is a kind of very good environment-friendly type fire extinguishing agent.The starter engaged with the gas storage cylinder container value starter interface of inert gas fire-fighting system is the drive unit that steel cylinder container value is opened.Starter can regular event except needs, and the connection also needing itself and container value seals, if the connection gas leakage of interface also can cause starter can not regular event, affects whole system and normally plays fire extinguishing effectiveness.Therefore, for the impermeability of this critical component of starter, be a quality critical point of starter, will carry out test and the detection of 100% before dispatching from the factory, this just needs a special testing tool.
Utility model content
The utility model is to overcome deficiency of the prior art, provides a kind of test device for air tightness of gas storage cylinder container value starter, simulates the connecting interface of container value and starter completely, and perfect air-tightness detection method, simplifies trace routine.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of test device for air tightness of gas storage cylinder container value starter, it is characterized in that: comprise air tightness tester body and valve inside, described air tightness tester body central is provided with threaded circular hole, be bolted with valve inside in described circular hole, be provided with the annular concave platform be connected with starter sealing joint in described air tightness tester body, described annular concave platform is communicated with circular hole.
Described annular concave platform root is provided with groove, is equipped with O-ring seals in described groove.
The outer circular cross sectional shape of described air tightness tester body is six sides or four directions.
Described air tightness tester body is provided with the pin hole of clamping starter near annular concave platform place radial direction.
Beneficial effect: compared with prior art, the utility model is that the air-leakage test of this critical component of starter provides special testing tool.The bubble-tight detection method of starter that it is perfect, simplifies trace routine.
Accompanying drawing explanation
Fig. 1 is the utility model and container value starter connection diagram.
Fig. 2 is outside drawing of the present utility model.
In figure: 1, air tightness tester body, 1-1, circular hole, 1-2, annular concave platform, 2, valve inside, 3, starter, 4, O-ring seals, 5, pin hole.
Embodiment
Below in conjunction with preferred embodiment, to the embodiment provided according to the utility model, details are as follows: embodiment
Refer to accompanying drawing, present embodiments provide a kind of test device for air tightness of gas storage cylinder container value starter, comprise air tightness tester body 1 and valve inside 2, described air tightness tester body central is provided with threaded circular hole 1-1, valve inside is bolted with in described circular hole, be provided with the annular concave platform 1-2 be connected with starter sealing joint in described air tightness tester body, described annular concave platform is communicated with circular hole.Described annular concave platform root is provided with groove, is equipped with O-ring seals 4 in described groove.The outer circular cross sectional shape of described air tightness tester body is six sides or four directions, and itself and starter screw by spanner easy to use.Air tightness tester intrinsic single shape is ladder shaft-like, and large circular portion is processed into six sides or four directions, and the cylindrical of little circular portion is provided with and the screw thread tested gas source interface and be connected.Described air tightness tester body is provided with the pin hole 5 of clamping starter near annular concave platform place radial direction.
The design simulates the connecting interface of container value and starter completely, according to the interface size of container value, air-proof condition and requirement, select the material that wall thickness intensity is enough, one end is starter interface, the other end is male connection, provides and the connecting interface testing source of the gas.
The course of work
1, the starter 3 through motion test is arranged on the air tightness test instrument of the number of joining O-ring seal;
2, by starter male connection shutoff, another connects driving gas circuit, and checks whether this connection is tight;
3, the other end of instrument is connected with the high-pressure air source of working pressure, and checks that whether this junction is tight;
4, open high-pressure source of the gas, then open driving source of the gas, pressurize 5 minutes, bubble-free is leaked as qualified.
5, test terminates first to close high-pressure air source, then closes driving source of the gas, then dismantles tested starter.
Above-mentioned detailed description of carrying out with reference to the test device for air tightness of embodiment to this kind of gas storage cylinder container value starter; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under the utility model general plotting and amendment, should belong within protection domain of the present utility model.
