Description
Technical field
The present invention relates to a kind of venting gas appliance, especially relate 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 carrys out switch valve by pressurized air as power source, and be have compressibility with air as power, so when source of the gas is filled with cylinder, first source of the gas is compressed in cylinder, and reaching certain energy subsequently could promote valve; Otherwise when cylinder is exitted, the air of compression needs to get rid of cylinder and also needs a process.Like this, modulating valve is because the compressibility of air makes valve event slow.And in the middle of process controls, especially when emergency, need modulating valve rapid response, directly return to modulating valve home.And modulating valve itself needs by positioning work piece to realize continuous control, but positioning work piece process source of the gas is limited in one's ability, is very slowly from positioning work piece exhaust.So, solve cylinder Quick air-discharge problem, modulating valve just can be made also to use under special circumstances.
Summary of the invention
Object of the present invention be exactly provide that a kind of using scope is wide to overcome defect that above-mentioned prior art exists, structure is simple, debug modulating valve easily on rapid exhaust.
Object of the present invention 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 and positioning work piece are all communicated with outside air feed source of the gas, 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 that positioning work piece exports 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, source of the gas delivery outlet and the logical of exhaust port close state, make the air Quick air-discharge in modulating valve cylinder.
Described modulating valve is pneumatic type modulating valve.
Described exhaust port directly passes into air.
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 invention is: when positioning work piece passes through control signal, change into and control the controller hole that gas signal outputs to source of the gas pilot valve, the spool of source of the gas pilot valve can be promoted after controller hole receives certain bleed pressure, opening source of the gas input hole makes source of the gas input, then be directly inputted to modulating valve cylinder by source of the gas delivery outlet, so just achieve the object that small-signal controls large-signal.And when modulating valve cylinder needs exhaust, positioning work piece can reduce to control source of the gas and export, the spool of source of the gas pilot valve is owing to can recover 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 directly exports from the exhaust port of source of the gas pilot valve, thus achieves the object of Quick air-discharge.
Compared with prior art, the present invention has the following advantages:
One, using scope is wide: modulating valve, owing to adding rapid exhaust, just can make modulating valve switch motion rapider.
Two, structure is simple: structure of the present invention uses simple, and full mechanical mechanism, the life-span is long.
Three, debugging is simple: when source of the gas pilot valve delivery pressure and positioning work piece delivery pressure imbalance, the source of the gas entering modulating valve can be caused unstable, and source of the gas pilot valve does not know that delivery pressure is the pressure that positioning work piece will export.When installing adjusting nut or balance nut additional, can be mated by adjustment nut, positioning work piece and source of the gas pilot valve reach balance, reach the operating state of modulating valve the best.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 present invention is described in detail.
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 and positioning work piece 1 are all communicated with outside air feed source of the gas 2, 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 positioning work piece 1 exports is changed into more powerful source of the gas signal by source of the gas pilot valve 3, and control source of the gas input hole 4, source of the gas delivery outlet 5 and the logical of exhaust port 7 close state, make the air Quick air-discharge in modulating valve 9 cylinder.Modulating valve 9 is pneumatic type modulating valve.Exhaust port 7 directly passes into air.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.
