Accompanying drawing explanation
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is front view of the present utility model;
Fig. 2 is side view of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 and Fig. 2, the band that it illustrates the utility model provides discharges and the agent structure of the gas control panel of the one-sided air feed connect.
As seen from the figure, this gas control panel primarily of suction valve group 1, regulate reduction valve 2, safety valve 3, discharge and take over road 4, high-pressure manometer 5, high-pressure manometer 6, mounting base assembly 7 cooperatively interact composition.
Mounting base assembly 7, as carrying and the arrangement parts of whole gas control panel, other constituent elements for control panel provides settles platform accordingly.Concrete, the upper surface of this arrangement bottom deck assembly 7 is a plane, as arrangement platform, for concentrated arrangement suction valve group 1, adjustment reduction valve 2, safety valve 3, discharge and take over road 4, and this arrangement bottom deck assembly 7 is arranged on bottom whole air supply system with fixing whole module.
Suction valve group 1, is arranged on mounting base assembly 7, and the setting position for suction valve group 1 can be determined according to the actual requirements, and illustrated example is the right side being arranged on mounting base assembly 7.
This valve group 1 comprises an air inlet switch control valve 11 and one and purges control valve 12, and air inlet switch control valve 11 controls air inlet switch, purges control valve 12 and does system purge use, to ensure clean for air purge in pipeline after left side ventilation bottle.
Concrete, air inlet switch control valve 11 and purging control valve 12 are made up of corresponding diaphragm valve respectively, adopt seamless welding to connect between the two, are fixed on (as shown in Figure 2) on mounting base assembly 7 by mounting screw 8; Wherein, air inlet switch control valve 11 entirety is fixed on the right lower side of mounting base assembly 7, purges control valve 12 and is positioned at upper right side.The suction port A of air inlet switch control valve 11 connects source of the gas (as gas cylinder) as the suction port (being also the suction port of whole gas control panel) of whole suction valve group 1, and its air outlet connects the suction port regulating reduction valve 2; Purge the floss hole (be also the floss hole of whole gas control panel) of floss hole C as whole suction valve group 1 of control valve 12.
Realize the control to air feed source of the gas by the simple suction valve group of structure in this programme, control corresponding air inlet switch by air cock control valve 11, control being switched on or switched off of source of the gas thus; If downstream allows to be interrupted source of the gas, there will be interruption air feed when changing steel cylinder, entering gas piping without air after can ensureing to change steel cylinder by the purging escape cock arranged, thus entering gas downstream pipeline without air after ensureing to change steel cylinder.
Regulate reduction valve 2, be specially setting decompressor, it is placed on mounting base assembly 7, and is positioned horizontally in the outlet port of air inlet switch control valve 11 in suction valve group.The suction port of this setting decompressor 2 connects with the air outlet of air inlet switch control valve 11, and setting decompressor 2 air outlet connects with the suction port of safety valve 3.
High-pressure manometer 6 and low pressure gauge 5 are set respectively at the pressure hole place of setting decompressor 2 and low pressure hole place simultaneously.
The adjustment reduction valve 2 arranged thus can regulate the pressurized gas that air inlet switch control valve 11 is carried, and the gas of elevated pressures is reduced to low-pressure gas, and the working pressure needed for ensureing keeps steady state from start to finish.
Safety valve 3, it is placed in the lower left side of mounting base assembly 7, and is positioned horizontally in the air outlet place regulating reduction valve 2.The suction port of this safety valve 3 is relative with regulating the air outlet level of reduction valve 2, and connects with it; The air outlet B of safety valve 3, as the air outlet of whole control panel, stretches out from the left side level of mounting base assembly 7, for downstream gas equipment air feed; The floss hole of safety valve 3 is positioned at the top of safety valve 3, the floss hole C purging control valve 12 in suction valve group 1 is connected to by discharging and taking over road 4, concrete, discharge and realize being connected by a tee union 9 between the floss hole C taking over road 4 and purging control valve 12 and connect.
This programme by arranging safety valve 3 on output pipe, effectively can prevent reducer pressure from climbing and bring danger to decompressor and downstream pipe and equipment use, can releasing pressure automatically when downstream pressure exceedes setting pressure.
The band formed according to such scheme discharge and the gas control panel of the one-sided air feed connect when carrying out work, connect gas cylinder by suction port A on it, regulate reduction valve 2 to adopt and set reduction valve, set corresponding pressure relief value by this setting decompressor 2.
Gas enters from suction port A, enters into air inlet switch control valve 11, and controlling to be allowed for access by the keying of air inlet switch control valve 11 regulates reduction valve 2.
After air feed gas enters adjustment reduction valve, on the upside of reduction valve, pressure gauge 6 will show air-source inflow force value, then by reduction valve regulating handle, regulate setting delivery pressure, on the upside of decompressor, display is used outlet pressure value by pressure gauge 5, will be the constant air feed in downstream.
The air feed gas regulated through decompression enters into safety valve 3 by regulating the air outlet of reduction valve 2.Gas after safety valve 3 from left side outlet B to downstream air feed.Joint wherein above safety valve is the floss hole of safety valve, is connected with a tee union in the purging exhaust-control valve outlet port in suction valve group 1 by discharging and taking over road 4.When toxic and harmful decompression is used, if reduction valve is because Long-Time Service or gas reason cause decompressor to occur, pressure climbs, the setting pressure being increased to safety valve when pressure is that safety valve is opened automatically, make gas through discharging and taking over road 4, discharge by purging floss hole C or reclaim, to guarantee down-stream system safety again.
Simultaneously, floss hole due to safety valve is distributed in the top of safety valve, and floss hole and discharge blow valve port are at grade, thus can realize safety relief pipeline, purge discharge pipe effectively gather together make system pipeline connect more succinct, easy for installation.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
