Description
Technical field
The utility model relates to a kind of venting gas appliance, especially relates to the rapid exhaust on a kind of modulating valve.
Background technique
At chemical enterprise, modulating valve is the most general process equipment, and the running of modulating valve is to carry out switch valve by pressurized air as power source, and be to have compressibility with air as power, so in the time that source of the gas is filled with cylinder, first source of the gas is compressed in cylinder, reaches subsequently certain energy and could promote valve; Otherwise in the time that cylinder is exitted, the air of compression need to be got rid of cylinder and also need a process.Like this, modulating valve is because the compressibility of air makes valve event slow.And in the middle of process control, in the time of emergency, need modulating valve rapid response especially, directly return to modulating valve home.And modulating valve itself is to realize continuous control by positioning work piece, but positioning work piece is processed the limited in one's ability of source of the gas, is very slowly from positioning work piece exhaust.So, solve cylinder Quick air-discharge problem, just can make modulating valve also can use under special circumstances.
Model utility content
The purpose of this utility model be exactly provide in order to overcome the defect that above-mentioned prior art exists a kind of using scope wide, simple in structure, debug the rapid exhaust on modulating valve easily.
The purpose of this utility model can be achieved through the following technical solutions:
Rapid exhaust on a kind of modulating valve, before being connected to modulating valve, described venting gas appliance comprises source of the gas pilot valve, positioning work piece and source of the gas PRESSURE PIPE, described source of the gas pilot valve is provided with controller hole, source of the gas input hole, source of the gas delivery outlet and exhaust port, described controller hole is connected with the signal output part of positioning work piece, described source of the gas input hole is all communicated with outside air feed source of the gas with positioning work piece, described source of the gas delivery outlet is connected with the cylinder of modulating valve by source of the gas PRESSURE PIPE, the control signal of positioning work piece output is changed into more powerful source of the gas signal by described source of the gas pilot valve, and control source of the gas input hole, the logical state that closes of source of the gas delivery outlet and exhaust port, make the air Quick air-discharge in modulating valve cylinder.
Described modulating valve is pneumatic type modulating valve.
Described exhaust port directly passes into atmosphere.
Described source of the gas PRESSURE PIPE is metal tube, plays source of the gas importing effect.Described source of the gas pilot valve adopts metallic material, sturdy and durable.
The working principle of rapid exhaust of the present utility model is: when positioning work piece passes through control signal, change into the controller hole that control gas signal outputs to source of the gas pilot valve, the spool that promotes source of the gas pilot valve is understood after receiving certain bleed pressure in controller hole, open source of the gas input hole and make source of the gas input, then be directly inputted to modulating valve cylinder by source of the gas delivery outlet, so just realized the object of small-signal control large-signal.And in the time that modulating valve cylinder needs exhaust, positioning work piece can reduce to control source of the gas output, the spool of source of the gas pilot valve is owing to can recovering source of the gas input hole closed condition under acting force of the spring, now, the source of the gas delivery outlet of source of the gas pilot valve is directly communicated with exhaust port, large quantity of air in modulating valve cylinder is directly exported from the exhaust port of source of the gas pilot valve, thereby has realized the object of Quick air-discharge.
Compared with prior art, the utlity model has following advantage:
One, using scope is wide: modulating valve, owing to having increased rapid exhaust, just can make modulating valve switch motion rapider.
Two, simple in structure: the utility model structure is used simple, full mechanical mechanism, the life-span is long.
Three, debugging is simple: source of the gas pilot valve delivery pressure is during with positioning work piece delivery pressure imbalance, and the source of the gas that can cause entering modulating valve is unstable, and source of the gas pilot valve does not know that delivery pressure is the pressure that positioning work piece will be exported.While installing adjusting nut or balance nut additional, can mate by adjustment nut, positioning work piece and source of the gas pilot valve reach balance, reach the operating state of modulating valve the best.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 is positioning work piece, 2 is air feed source of the gas, and 3 is source of the gas pilot valve, and 4 is source of the gas input hole, and 5 is source of the gas delivery outlet, and 6 is controller hole, and 7 is exhaust port, and 8 is source of the gas PRESSURE PIPE, and 9 is modulating valve, and 10 is balance nut.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
Rapid exhaust on a kind of modulating valve 9, as shown in Figure 1, before being connected to modulating valve 9, venting gas appliance comprises source of the gas pilot valve 3, positioning work piece 1 and source of the gas PRESSURE PIPE 8, source of the gas pilot valve 3 is provided with controller hole 6, source of the gas input hole 4, source of the gas delivery outlet 5 and exhaust port 7, controller hole 6 is connected with the signal output part of positioning work piece 1, source of the gas input hole 4 is all communicated with outside air feed source of the gas 2 with positioning work piece 1, source of the gas delivery outlet 5 is connected with the cylinder of modulating valve 9 by source of the gas PRESSURE PIPE 8, the control signal that source of the gas pilot valve 3 is exported positioning work piece 1 changes into more powerful source of the gas signal, and control source of the gas input hole 4, the logical state that closes of source of the gas delivery outlet 5 and exhaust port 7, make the air Quick air-discharge in modulating valve 9 cylinders.Modulating valve 9 is pneumatic type modulating valve.Exhaust port 7 directly passes into atmosphere.Source of the gas PRESSURE PIPE 8 is metal tube, plays source of the gas importing effect.Source of the gas pilot valve 3 adopts metallic material, sturdy and durable.
