Description
Technical field
The present invention is relevant for the gas recovery valve group of bottle blowing machine with one, it can provide one of bottle blowing machine bottle blowing module to produce the first pressure air blowing, the second pressure air blowing, gas recovery and exhaust operation, and has the advantage that reduces gas dead band and accelerate gas recovery operation.
Background technology
Commonly use the bottle blowing module of bottle blowing machine, as shown in No. M302467th, TaiWan, China patent announcement, to be connected with one first pressure gas source, one second pressure gas source and a gas recycling module by a gas recovery valve group, to carry out the first pressure air blowing, the second pressure air blowing, gas recovery and exhaust operation.Wherein, this gas recovery valve group is to include one first pressure valve, one second pressure valve, an air bleeding valve and a recovery valve.Moreover, there is dealer to use arrange convenient and improve as the length in M302467 patent loop own causes the factors such as pressure-air waste, develop a kind of gas concentration unit as shown in No. M402188th, TaiWan, China patent announcement.
The valve body of right above-mentioned located by prior art is formed by the valve body of two mouthfuls two, only can control merely the switch of the first pressure gas source, the second pressure gas source, gas recycling module and exhaust outlet, and the length of bulk loop is fixed.While carrying out the first pressure air blowing and the air blowing of the second pressure as M402188 patent, gases at high pressure all obtain first and all valve inner passages are full of to (amounting to 4 valve bodies as an example of M402188 patent example), could carry out bottle blowing operation to bottle blowing module, unnecessary valve inner passage forms gas dead band, causes gases at high pressure waste.Though each bottle blowing may only cause the gas waste of several CC, with the output of current bottle blowing machine be about 20,000/hour～50,000 bottles/hour, the gases at high pressure that caused are wasted also considerable.
Moreover, when commonly using bottle blowing machine and carrying out the second pressure air blowing operation, for avoid pressure-air to be directly recovered by mistake, therefore recovery valve is in closed condition, when commonly using bottle blowing machine in the time that the second pressure air blowing operation switches to gas recovery operation, obtain and first really close after the second pressure valve, then open recovery valve to carry out gas recovery.But thus, need the reaction time that two valve bodies switch to switch to gas recovery operation from the second pressure air blowing operation, accumulate and also cause many processing procedure time delays.
Utility model content
The shortcoming of opening prior art on comprehensive, comprises that the length of bulk loop is fixed haply, easily produces gas dead band, causes gases at high pressure waste.And in view of solving above-mentioned shortcoming, this case proposes a kind of scheme of gas recovery valve group, this scheme has adjustable loop state, reduces gas dead band and accelerates gas and reclaim the advantage of operation.
For achieving the above object, the technical solution used in the present invention is:
The present invention is to provide a kind of gas recovery valve group, includes:

Understanding after above-mentioned this case detailed structure, is below to describe in detail one by one for the operating principle of this case:
As shown in Figure 4, in the time that bottle blowing machine carries out the first pressure air blowing, this gas recovery valve group 1 is the first pressure pilot valve 25 to be switched to the first controlled valve B251 opens, second switch valve B252 closes, and the second pressure pilot valve 35 switches to, the first controlled valve C351 closes, the state of second switch valve C352 unlatching, make the first pressure gas source 91 be communicated to bottle blowing module 93 by the first pressure communication mouth 24, the second pressure series connection mouth 33 and the second pressure communication mouth 34, with the gases at high pressure that utilize the first pressure gas source 91, bottle blowing module 93 is blown.Wherein, connected entrance 14 and the first pressure series connection mouthfuls 23 is because second switch valve B252 closes, and enters without gas, can reduce the formation in gas dead band.And now reclaim that air bleeding valve 10 can switch to that the first controlled valve A151 opens in advance, the second switch valve A152 state of closing makes to reclaim mouthfuls 12 in advance, keep being communicated with (as shown in Fig. 4) between connected entrance 14 and the series connection of the first pressure mouthfuls 23, but B252 closes because of second switch valve, the gases at high pressure of the first pressure gas source 91 can't flow into.
As shown in Figure 5, when bottle blowing machine carries out the second pressure while blowing, this gas recovery valve group 1 is the second pressure pilot valve 35 to be switched to the first controlled valve C351 closes, the state of second switch valve C352 unlatching.Make the second pressure gas source 92 be communicated to bottle blowing module 93 by the second pressure breathing mouth 32 and the second pressure communication mouth 34, with the gases at high pressure that utilize the second pressure gas source 92, bottle blowing module 93 is blown.Wherein, reclaim air bleeding valve 10, the first pressure valve 20 and the series connection of the second pressure mouthfuls 33 because the first controlled valve C351 closes, and enter without gas, also there is the effect that reduces the formation of gas dead band.
As shown in Figure 6, in the time that bottle blowing machine carries out gas recovery, this gas recovery valve group 1 is that recovery exhaust pilot valve 15 is remained unchanged, and the first pressure pilot valve 25, the second pressure pilot valve 35 switch to the first controlled valve (B, C) 251,351 unlatchings, second switch valve (B, C) 252,352 states of closing.Make gas recycling module 90 be communicated to bottle blowing module 93 by gas recovery valve group 1, with by the pressure-air recycling of bottle blowing module 93.
It is worth mentioning that, the first pressure valve 20 of the present invention is in the time that the second pressure valve 30 is carried out the second pressure air blowing, to switch in advance action, make in advance to reclaim mouth 12, between connected entrance 14 and the first pressure series connection mouth 23, keep being communicated with, be pre-formed and reclaim loop, in the time that bottle blowing machine carries out gas recovery, only the second pressure pilot valve 35 need be switched to the first controlled valve C351 opens, the state that second switch valve C352 closes, this second pressure valve 30 can make bottle blowing module 93 be communicated with gas recycling module 90 simultaneously, the reaction time that only needs single valve body to switch, can complete the switching of the second pressure air blowing operation and gas recovery operation, can improve the reaction speed of operation, reduce processing procedure required time.
Moreover, as shown in Figure 7, be down to predetermined pressure lower time when the pressure-air of bottle blowing module 93 because reclaiming, reclaim exhaust pilot valve 15 and switch to that the first controlled valve A151 closes, the state of second switch valve A152 unlatchings, 13 releases of remaining gas permeation exhaust outlet are discharged in atmosphere.
By describing in detail above, can make to know this skill person and understand that the present invention is really completely different with the design of commonly using, and has suitable novelty.And the present invention has effect that the design of commonly using cannot be expected, meet in fact the positive important document that patent is checked and approved, whence proposes patent application in accordance with the law.
Though the present invention explains with a preferred embodiment, be skillful in this skill person and can do various multi-form changes not departing under the present invention spirit and category.Above illustrated embodiment is only in order to the present invention to be described, non-in order to limit the present invention's scope.Such as do not disobey various modifications or the variation that spirit of the present invention is engaged in, all categories that this invention is intended to protection that belongs to.
