Detailed description of the invention
Please refer to Fig. 1 to Figure 11, the Soda water machine pressure protection agency in figure, comprise an exhaust bracket 1, Manual air exhausting mechanism 2, automatic vent mechanism 3; Wherein exhaust bracket 1 is imported to by the carbon dioxide in gas cylinder 4 in above-mentioned two exhaust gears thus can be discharged by gas in time when bottle inner high voltage situation to avoid bottle explosion; Manual air exhausting mechanism 2 utilizes manually to be discharged by the gas in bottle by flowing mode, and automatic vent mechanism 3 utilizes automated manner to be discharged by the gas in bottle.
Exhaust bracket 1 has a discoidal base 11 and is convenient to install, and have air inlet pipe 12 and blast pipe 13 on the pedestal 11, wherein blast pipe 13 can bi-directional venting, thus is imported to by gas in Manual air exhausting mechanism 2 and automatic vent mechanism 3 simultaneously.
Manual air exhausting mechanism 2 comprises a manual spool 21, manual valve seat 22, manual exhaust valve 23; Manual spool 21 moves downward for driving the moving air permeable pipe 232 in manual exhaust valve 23 under external force, and then is discharged by the gas in bottle.Manual valve seat 22 is for being communicated with exhaust bracket 1 fixed manual spool 21 and manual exhaust valve 23 simultaneously.Manual exhaust valve 23 for discharging the gas in bottle under the effect of manual spool 21.Manual spool 21 has sealing ring, and manual spool 21 remains sealing state with manual valve seat 23.Together with manual valve seat 22 and manual exhaust valve 23 are mated by internal and external threads, it is inner with manual exhaust valve 23 that manual spool 21 is fixed on manual valve seat 22, and this manual spool 21 top exceeds manual valve seat 22 top and so conveniently presses; The side of exhaust bracket 1 is communicated with manual valve seat 22, like this gas is imported to Manual air exhausting mechanism 2 inner.Manual valve seat 22 top in Fig. 6-7 is tapered, so the manual spool 21 of convenient installation and minimizing volume.Manual exhaust valve 23 comprises the fixture 234 of moving air permeable pipe 232, Compress Spring 233, band air-vent of a lower valve base body 231, band air-vent 2321; Moving air permeable pipe 232, Compress Spring 233, fixture 234 are fixed in lower valve base body 231 from top to bottom successively, and lower valve base body 231 is fixed on manual valve seat 22; When manual spool 21 pressed move down time, it drives moving air permeable pipe 232 to move down, due to moving air permeable pipe 232 having air-vent 2321, gas in such bottle will flow in lower valve base body 231 from exhaust bracket 1, because fixture 234 is also with air-vent, such gas just can be discharged to external environment from fixture 234.
Automatic vent mechanism 3 comprises an automatic valve seat 31, upper air bleeding valve 32, lower air bleeding valve 33 automatically automatically; Simultaneously the effect of automatic valve seat 31 gas in exhaust bracket 1 is imported to automatic vent mechanism 3 inside to support automatic air bleeding valve up and down; Automatically the effect of upper air bleeding valve 32 is when the air pressure in bottle exceedes design pressure, and it is automatically opened and makes gas automatically from air bleeding valve discharge automatically.Automatically the effect of lower air bleeding valve 33 is when upper air bleeding valve 32 fault automatically, and it starts to make gas automatically to discharge from air bleeding valve 33 automatic automatically, plays the function of two pipe protections like this.Automatic valve seat 31 in figure is communicated with exhaust bracket 1 opposite side, manual in the drawings valve seat 22 and automatic valve seat 31 symmetry be arranged on exhaust bracket 1 left and right sides; Automatically upper air bleeding valve 32, automatically lower air bleeding valve 33 are fixed on the two ends up and down of automatic valve seat 31 and are communicated with.Automatically upper air bleeding valve 32 in figure comprises top cover 321, upper valve base Compress Spring 322, automatic upper valve core 323 of a band air-vent; Top cover 321 and automatic valve seat 31 are coordinated by internal and external threads thus are fixed on automatic valve seat 31 top, and automatic upper valve core 323 puts upper valve base Compress Spring 322 and is fixed on automatic valve seat 31 inside; Automatic upper valve core 323 is taper seat with the face contacted bottom automatic valve seat 31, and automatic upper valve core 323 side is provided with a sealing ring, and automatic upper valve core 323 is tightly connected by sealing ring and automatic valve seat 31.When the pressure in bottle exceedes design pressure, first gas drive automatic upper valve core 323 move upward thus discharged by top cover 321 by gas.
Automatically lower air bleeding valve 33 comprises 332, one, an automatic bottom spool 331, automatic bottom spool Compress Spring band automatic lower valve base 333, lower air bleeding valve main body 334 with air-vent; Automatic bottom spool 331 puts automatic bottom spool Compress Spring 332 and is fixed on lower air bleeding valve main body 334 inside; This lower air bleeding valve main body 334 to be fixed on bottom automatic valve seat 31 and to be communicated with.Automatic bottom spool 331 side is provided with a sealing ring, and automatic bottom spool 331 is tightly connected by sealing circle and lower air bleeding valve main body 334.When upper air bleeding valve 32 breaks down automatically, gas can drive automatic bottom spool 331 to move down, and such gas is discharged in external environment by the automatic lower valve base 333 of band air-vent and reaches depressurization.
The place that Soda water machine in Fig. 1 and Fig. 2 and common Soda water machine are distinguished is, it uses pressure protection agency above-mentioned, and other structure does not then do too much change.
More than show and describe general principle of the present invention, principal character and advantage of the present invention; the technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.
