Mounting base assembly 9 is arranged on the bottom of control panel with fixing whole module.The upper surface of this mounting base assembly 9 is a plane, for other comprising modules of fixing control panel.
Left side suction valve group 1, as the first suction valve group, is arranged on the left side of mounting base assembly 9.This valve group 1 comprises an air inlet switch control valve 101 and one and purges control valve 102, and air inlet switch control valve 101 controls air inlet switch, purges control valve 102 and does system purge use, to ensure clean for air purge in pipeline after left side ventilation bottle.
Concrete, air inlet switch control valve 101 and purging control valve 102 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 9 by mounting screw 12; Wherein, air inlet switch control valve 101 entirety is positioned at downside, purges control valve 102 and is positioned at upside.The suction port A of air inlet switch control valve 101 connects source of the gas (as gas cylinder) as the suction port of whole left side suction valve group 1, and its air outlet connects setting decompressor 2; Purge the floss hole of control valve 102 by discharging and taking over the floss hole that road 6 is connected to safety valve 7.
Right side suction valve group 5, as the second suction valve group, is arranged on the right side of mounting base assembly 9 relative to left side suction valve group 1.This valve group 5 comprises an air inlet switch control valve 501 and one and purges control valve 502, and air inlet switch control valve 501 controls air inlet switch, purges control valve 502 and does system purge use, to ensure clean for air purge in pipeline after right side ventilation bottle.
Concrete, air inlet switch control valve 501 and purging control valve 502 are made up of corresponding diaphragm valve respectively, adopt seamless welding to connect between the two, are fixed on mounting base assembly 9 by mounting screw 12; Wherein, air inlet switch control valve 501 entirety is positioned at downside, purges control valve 502 and is positioned at upside.The suction port B of air inlet switch control valve 501 connects source of the gas (as gas cylinder) as the suction port of whole right side suction valve group 2, and its air outlet connects and switches decompressor 4; The floss hole purging control valve 502 is discharged by tee union 13 connection and is taken over road 8, then by discharging and taking over another floss hole that road 8 is connected to safety valve 7, wherein tee union 13 the 3rd exports as purging floss hole D, as discharge or the recovery of gas.
Setting decompressor 2, shuttle valve 3, switching decompressor 4 complement each other to form corresponding semi-automatic switcher structure to safety valve 7, and entirety is placed in the middle part of mounting base assembly 9, for controlling the handoff-security between left side suction valve group 1 and right side suction valve group 5.
Wherein, shuttle valve 3 is arranged on the downside in the middle part of mounting base assembly 9, and the suction port of its left and right sides connects the air outlet of setting decompressor 2 respectively and switches the air outlet of decompressor 4.
Be positioned at the setting decompressor 2 on the left of shuttle valve 3, it is arranged on the outlet port of left side suction valve group 1, connects with the air outlet of air inlet switch control valve 101.Pressure hole place on the upside of setting decompressor 2 is provided with left pressure table 10.
Be positioned at the switching decompressor 4 on the right side of shuttle valve 3, it is arranged on the outlet port of right side suction valve group 5, connects with the air outlet of air inlet switch control valve 501.The pressure hole place switched on the upside of decompressor 4 is provided with right atrial pressure table 11.
Safety valve 7 is arranged on the outlet port of shuttle valve 3, and the suction port of this safety valve 7 exports with shuttle valve 3 and is connected, and two floss holes of the left and right sides are connected with discharging and take over road 6 and discharge and take over road 8 respectively.
This safety valve 7 is arranged on corresponding output pipe, and can prevent reducer pressure from climbing and bring danger to decompressor and downstream pipe and equipment use, be can releasing pressure automatically when downstream pressure exceedes setting pressure.
Discharge in control panel is also taken over road 6 and is discharged and take over road 8, purges respectively as safety valve floss hole and left side the outlet connecting pipe road that control valve and right side purge control valve.
According to such scheme form semi-automatic switching gas control panel when carrying out work, be connected two gas cylinders respectively by suction port A with B on it, set corresponding pressure relief value by the setting decompressor 2 in left side.
Left gas enters from suction port A, enters left side decompressor (namely setting decompressor) through left side air inlet switch control valve 101, and on the upside of decompressor, pressure gauge 10 shows left side air inlet pressure force value, enters shuttle valve 3 by decompressor after being reduced pressure; Top right gas enters from suction port B, and enter right side decompressor (namely switching decompressor 4) through right side air inlet switch control valve 501, on the upside of decompressor, pressure gauge 11 shows right side air inlet pressure force value, enters shuttle valve 3 by decompressor after being reduced pressure.When right side decompressor (namely switch decompressor 4) finger to the left time, left side decompressor delivery pressure is higher than right side decompressor, and under gas pressure effect, the right side inlets of shuttle valve is closed, by left side air feed; When left side is along with cylinder gas pressure drop, when left side decompressor delivery pressure is lower than right side decompressor delivery pressure, the left side inlet close of shuttle valve under gas pressure effect, system automatically switches to right side air feed, ensures the constant air feed in downstream thus.
Because shuttle valve 3 outlet is connected with the import of safety valve 7, after gas enters safety valve, exported C to downstream air feed from safety valve.Because two, the left and right joint of safety valve is all as the floss hole for safety valve, left side floss hole is connected with the outlet that left side purges control valve 102 through discharging and taking over road 6, right-side outlet through discharging and taking over road 8, then is connected with the outlet of right side floss hole by a tee union.When toxic and harmful decompression is used, because decompressor Long-Time Service or gas reason cause decompressor to occur, pressure climbs, and when pressure is increased to the setting pressure of safety valve, safety valve is opened automatically, gas is discharged by purging floss hole D or is reclaimed, to guarantee down-stream system safety.
Simultaneously, floss hole due to safety valve is distributed in the left and right sides of safety valve, and the blow valve port of floss hole and the left and right sides is at grade, thus can realize safety relief pipeline, purge discharge pipe effectively gather together make system pipeline connect more succinct, easy for installation.
As from the foregoing, in this programme, realizing semi-automatic switching air feed by two decompressors, ensureing the uninterrupted air feed when changing steel cylinder, realize providing continual source of the gas to downstream; After ensureing to change steel cylinder, enter gas piping without air, this programme enters gas downstream pipeline without air by arranging two purging control valves after ensureing changing steel cylinder simultaneously.
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.
