Abstract
The utility model belongs to the fire-extinguishing technical field and relates to a pressure container valve for a fire-extinguishing device. The utility model is a normally closed valve, which is used for storing fire-extinguishing gas at ordinary times and releasing the fire-extinguishing gas in the pressure container during operation. The pressure container valve comprises a hand air valve (1), a lower valve body (2), a safety screw (3), a metal sealing diaphragm (4), a clamping ring (5), an upper valve body (6), a piercing needle (7), a compression screw (8), a charge (9), a piston (10), a guide sleeve (11), a sealing ring (12), a gas circuit triplet (13), a pipeline (14), etc. The pressure container valve utilizes the differential pressure principle to cause the piston (10) to drive the piercing needle (7) installed on the piston to pierce the metal sealing diaphragm (4) under the action of the pressure gas. The utility model has three opening modes: manual operation, pneumatic operation and electric operation; because gas of all the three opening modes can be ensured, the situation that the valve can not be opened is not likely to occur.
Description
Technical field:
The utility model belongs to the fire prevention field, relate to the pressurized container valve that a kind of fire-fighting fire-extinguishing equipment is used, it is at ordinary times in order to store fire-suppressant gas, a kind of normally close valve that during work the fire-suppressant gas in the pressurized container is discharged, it is the main actuating device that control fire-fighting fire extinguishing gas is carried at a distance, broken, leads to.
Background technique:
The existing used pressurized container valve of fire-fighting fire-extinguishing equipment mainly be a kind of be the valve of energy-accumulating element with the spring, spring is in compressive state under gas is sealed state up for safekeeping, the valve mode of opening of this valve has three kinds: manual, pneumatic and electronic, three kinds of opening ways all are to promote to puncture pin by spring force to move downward and puncture the metallic seal diaphragm and work.And there is the possibility of spring failure in this mechanical component of spring, in case spring failure punctures pin and can't move downward and puncture the metallic seal diaphragm, valve can't be opened.Well imagine that big fire is current, can't open the valve of fire extinguisher, fire-suppressant gas can not discharge, and will produce what kind of consequence.In addition, this valve compresses trim ring by inner nut and the metallic seal diaphragm seals, and the interior six sides processing of inner nut is comparatively difficult, manufacturability is poor, and difficult sealing is to guarantee.
Summary of the invention:
The purpose of this utility model is that a kind of novel pressurized container valve will be provided, and the possibility that valve can't be opened is reduced to zero, and makes its easy processing, assembling and good airproof performance.
The purpose of this utility model is achieved in that utilizes differential pressure principle, and it utilizes piston to drive the dress broken metallic seal diaphragm of acupuncture that punctures thereon under the pressed gas effect and works.The opening ways of this valve also has three kinds: manual, pneumatic, electronic, they all utilize pressed gas to promote piston motion and drive valve, because the gas of these three kinds of opening ways all can guarantee, so just the situation that valve can't be opened can not occur.The utility model compresses trim ring by upper valve body in addition and the metallic seal diaphragm seals, and upper valve body is a solid of rotation, and technology capability is good, good airproof performance.
The utility model and be the vessel valve of the energy-accumulating element following advantage of having compared with the spring:
1, the unlatching of valve not only flexibly but also reliable;
As long as 2 can promote piston just the situation that valve can't be opened can not appear;
3, processing, easy for installation.
Description of drawings:
Accompanying drawing is the sectional drawing of the utility model pressurized container valve.
The manual air valve of .1. 2. descends valve body among the figure, 3. safety screw, and 4. metallic seal diaphragm, 5. trim ring, 6. upper valve body 7. punctures pin, 8. housing screw, 9. cartridge bag, 10. piston, 11. guide sleeves, 12. seal rings, 13. gas circuit threeways, 14. pipelines.
Embodiment:
Following valve body (2) is installed in by scyewed joint on the pressurized container A that stores fire-suppressant gas, and metallic seal diaphragm (4) relies on the screw thread of upper valve body (6) and following valve body (2) to screw power by trim ring (5) and is fastened onto down on the valve body (2), forms tight seal; Upper valve body (6) and following valve body (2) are scyewed joint.Safety screw (3) is installed in down on the valve body (2), and too high when ambient temperature, when the gas pressure among the pressurized container A was too high, portion gas can overflow by safety screw (3), reduces the pressure among the pressurized container A.Upper valve body (6) is a scyewed joint with guide sleeve (11), piston (10) and puncture pin (7) and be installed in the cavity that upper valve body (6) and guide sleeve (11) form, puncture pin (7) and be installed in the bottom of piston (10), it between the two drive fit, effect by housing screw (8) with piston (10) with puncture pin (7) and be connected as a body common static or motion.Upper valve body (6), piston (10) and guide sleeve (11) assembling back form the B of sealed air chamber, produce differential pressure face C.When gas acts on the differential pressure face C, piston (10) and puncture pin (7) and can move downward along guide sleeve (11) and upper valve body (6), in order to guarantee the B of sealed air chamber sealing, between piston (10) and guide sleeve (11), the upper valve body (6) seal ring (12) is housed.Manually air valve (1) is installed in down on the valve body (2), manually air valve (1) links to each other with gas circuit threeway (13) by pipeline (14), when opening manual air valve (1), be that the fire-suppressant gas of sealing up for safekeeping among the pressurized container A can enter into pneumatic air valve (1) in the following valve body (2), enter into gas circuit threeway (13) by pipeline (14).When needs pressurized container opening of valves, make gassy in the B of sealed air chamber, gas acts on the differential pressure face on the C, and piston (10) will drive the pin of adorning thereon (7) that punctures and move downward under the gas pressure effect, puncture metallic seal diaphragm (4), put out a fire thereby discharge fire-suppressant gas.Gas source among the B of sealed air chamber has three kinds: the 1. extraneous gas that starts in the steel cylinder; 2. the fire-suppressant gas among the pressurized container A, i.e. self gas; 3. the gas that produces of cartridge bag (9), these three kinds of gases respectively by pneumatic, manually reach electronic three kinds of modes and obtain.Cartridge bag when electronic (9) is received electric signal and is started, the gas that cartridge bag (9) produces is pooled among the B of sealed air chamber, act on the differential pressure face C, promote piston (10) and drive the dress pin (7) that punctures thereon and move downward and puncture metallic seal diaphragm (4), the fire-suppressant gas that stores in the release pressure container A; When pneumatic, the extraneous gas that starts in the steel cylinder comes together in the B of sealed air chamber by gas circuit threeway (13), promotes piston (10) and drives the pin of adorning thereon (7) that punctures and move downward and puncture metallic seal diaphragm (4); In the time of manually, the manual air valve (1) of outwarding winding, the fire-suppressant gas of sealing up for safekeeping among the pressurized container A enters the B of sealed air chamber by pipeline (14) and gas circuit threeway (13), act on the differential pressure face C, promote piston (10) and drive the dress pin (7) that punctures thereon and move downward and puncture the purpose that metallic seal diaphragm (4) reaches fire extinguishing.
