The specific embodiment
By reference to the accompanying drawings 1, Fig. 2, the structure of the utility model fire extinguisher bottle head valve is specific as follows:
The fire extinguisher bottle head valve comprises that first of upper valve body 9, lower valve body 11, bonnet, 6 and hollow punctures pin 7, first punctures pin 7 is hollow form, the center of bonnet, 6, upper valve body 9, lower valve body 11 is provided with through hole, first punctures pin 7 is contained in the described through hole, bonnet, 6, upper valve body 9 and lower valve body 11 are stacked successively from top to bottom, be provided with sealing gasket 4 between bonnet, 6 and the upper valve body 9 and be used for sealing, upper valve body 9 is installed together with lower valve body 11 usefulness pressure caps 10.
First punctures the piston 8 that is set with annular on the pin 7 middle part outer walls, and the top that bonnet, 6, upper valve body 11 inwalls, first puncture pin 7 outer walls and piston 8 consists of a closed chamber, is provided with the quick-fried box 5 of medicine in the closed chamber; The quick-fried box of this medicine 5 outsides are connected with terminal box 3; Be provided with annular crash roll 2 between upper valve body 9 and the lower valve body 11, crash roll 2 is with bellmouth, the first outer wall that punctures pin 7 bottoms is provided with the conical surface 21, and the hole wall of the bellmouth on this conical surface 21 and the crash roll 2 cooperates, and different angles have a plurality of breach on the crash roll 2; The first tip section that punctures pin 7 is with leg-of-mutton breach; First punctures below, pin 7 tips is provided with main film 1.
In addition, the first time in the present embodiment, broken pin 7 and second punctured the tip section of pin 19 all with leg-of-mutton breach.
The operation principle of this fire extinguisher bottle head valve:
When electricity started, terminal box 3 was connected with the quick-fried box 5 of the medicine of bottle valve inside, and when the impulsive force that quick-fried box 5 blasts of medicine produce, pushing piston 8 also drives first and punctures that pin 7 is downward fast to be moved and crash roll 2 is cracked, thereby punctures main film 1;
When manually booting, pull out first safety pin 15 and make 12 fractures of lead sealing band, and firmly take handle 13, puncture pin 19 with second and puncture secondary diaphragm 16, at this moment, hollow conduit 18 just in time communicates with the gas port of upper valve body 9 with lower valve body 11, the gas port that the pressed gas of fire extinguisher pharmacy jar 17 internal storage is run through to lower valve body 11 and upper valve body 9 by hollow conduit 18, sharply be forced into piston 8 tops, and pushing piston 8 drives first puncture pin 7 fast operation downwards, crash roll 2 is cracked, thereby puncture main film 1.
The impulsive force that the utility model fire extinguisher bottle head valve can rely on the medicine box blast to produce, the pushing piston drive punctures pin main film is punctured; Or manually driving handle makes second to puncture the broken secondary diaphragm of acupuncture, and the pressed gas in the pharmacy jar is by behind the gas port of bottle valve inside, and pushing piston drive first punctures pin main film is punctured.
This practical employing piston mode provides and punctures power and adopt crash roll to prevent misoperation, has solved that existing bottle valve produces because of vibrations that the inertia force mistake punctures diaphragm or because of the long-time compressed shortcoming that causes screen resilience to lose efficacy and cause diaphragm to be difficult for being punctured of spring.
The utility model fire extinguisher bottle head valve is applicable to have in the flask for medicinal preparations fire extinguisher of pressed gas, by the notch size of reasonable control crash roll, makes to puncture the diaphragm under the different pressures in the broken pharmacy jar of acupuncture.The utlity model has the advantages such as simple in structure, easy to use.
The utility model also has numerous embodiments, in every case in spirit of the present utility model and essential scope, any change of doing, is equal to replacements, improvement, all within the protection domain of utility model.
