Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.
Referring to Fig. 1-2; A kind of automatic inflation selector comprises the first straight-through cutting ferrule joint 1, integrated package 2, the second straight-through cutting ferrule joint 3, safety valve 4, priority valve 5, the first triplet card bell and spigot joint 6, pipeline 6, hexagon socket head cap screw 6, one-way valve 9, the second triplet card bell and spigot joint 10, mounting plate 11, GAUGE CONNECTOR 12 and pressure gauge 13.Integrated package 2 is fixed on the mounting plate 11 through hexagon socket head cap screw 8.
The first straight-through cutting ferrule joint 1 is fixed on the underpart of integrated package 2 through its outside thread, and the cutting ferrule joint of this first straight-through cutting ferrule joint 1 is and breathes the connection interface of gas cylinder 19.
The suction port of the air outlet of the suction port of priority valve 5, one-way valve 9, second straight-through cutting ferrule joint 3, the first straight-through cutting ferrule joint 1 and safety valve 4 is communicated with each other through the internal pipeline of integrated package 2.
Fig. 2 shows and is connected with the schematic diagram that the utility model is inflated the gas charging system of selector automatically; For the ease of explanation; Automatically inflating selector portion; Only show safety valve 4, priority valve 5 and one-way valve 9, other part of inflating selector automatically is not shown, and other part of this gas charging system includes storage gas cylinder group 14, air compressor 15, safety check 16, reduction valve 17, breathes gas cylinder 18, ball valve 19.
Below in conjunction with this schematic diagram, the working principle of the utility model is explained as follows:
In the following stated, P1 refers to that air compressor delivery pressure, P2 refer to store gas cylinder group pressure, P3 refers to that tidal air bottle pressure, P4 finger pressure mechanical compliance preface valve opening pressure, P5 refer to the reduction valve setting pressure.
At first, in gas charging system principle schematic shown in Figure 2, pressure sequence valve opening pressure P4 is all the time greater than reduction valve setting pressure P5.
When ball valve 19 is closed; After starting air compressor 15; Air compressor delivery pressure P1 will progressively raise, and when air compressor delivery pressure P1 equals pressure sequence valve opening pressure P4, inflates priority valve 5 conductings of selector automatically; The storage gas cylinder group pressure P 2 that stores gas cylinder group 14 will progressively raise, until balancing each other with air compressor delivery pressure P1.
Insert tidal air bottle pressure P3 this moment is zero breathing gas cylinder 18, and opens ball valve 19, and air compressor delivery pressure P1 descends immediately, and tidal air bottle pressure P3 is rapid and air compressor delivery pressure P1 balances each other; Air compressor delivery pressure P1 was lower than pressure sequence valve opening pressure P4 and stored gas cylinder group P2 this moment, inflated the priority valve 5 of selector automatically and will close.Store gas cylinder group pressure P 2 and open one-way valve 9 immediately; Tidal air bottle pressure P3 is progressively raise and reach balance through reduction valve 17 and the ball valve of opening 19; Store gas cylinder group pressure P 2 because air compressor delivery pressure P1 is lower than simultaneously, store gas cylinder group pressure P 2 and will close safety check 16, cut off air compressor 15 and breathe gas cylinder 18 and the path that stores gas cylinder group 14; Running along with air compressor 15; Air compressor delivery pressure P3 progressively brings up to greater than storing gas cylinder group pressure P 2, but when being lower than priority valve pressure P 4, air compressor delivery pressure P1 will close the one-way valve 9 of automatic inflation selector; Do not have conducting owing to inflate the priority valve 5 of selector automatically this moment, stores gas cylinder group 14 and just be cut off with the pipeline of breathing gas cylinder 18.The air compressor delivery pressure P1 of air compressor 15 directly progressively raises tidal air bottle pressure P3 through reduction valve 17 and ball valve 19;
After tidal air bottle pressure P3 reaches reduction valve 17 setting pressure P5; Because the effect of reduction valve 17; Tidal air bottle pressure P3 can not continue to raise, and air compressor delivery pressure P1 can continue along with the running of air compressor 15 to raise, when air compressor delivery pressure P1 equals pressure sequence valve opening pressure P4; Automatically priority valve 5 conductings of inflation selector, storing gas cylinder group pressure P 2 will raise and raise along with air compressor delivery pressure P1; As air compressor delivery pressure P1 during greater than the setting pressure of the automatic safety valve 4 of inflation selector, safety valve 4 is opened release, thereby plays the safety protection effect.
The utility model can guarantee in gas charging system, breathes gas cylinder in case insert, and when the pressure that stores the gas cylinder group during greater than the delivery pressure of air compressor, storing the gas cylinder group can be fast to breathing the gas cylinder inflation; When store gas cylinder group and air compressor delivery pressure balance or less than the time, the pneumatics function is preferably to breathing the gas cylinder inflation, has only after breathing gas cylinder and reaching required working pressure, air compressor just can be changed automatically to storage gas cylinder group and inflate.Thereby raising system inflation usefulness reduces operator's manipulation strength, is exempted from the air compressor frequent starting, helps energy saving and the maintenance that reduces system.
