Abstract
The utility model discloses a container valve of a fire extinguisher. The container valve of the fire extinguisher comprises a valve body and a piston inside the valve body. The piston extends out of a piston connection end of the valve body and is fixedly arranged inside a piston seat. One end of the piston seat is fixedly arranged on the valve body and is fixedly provided with a cylinder. An L-shaped connection end of a connecting rod and a top plate is provided with a pry hole. The end portion of the connecting rod is fixedly arranged at the other end of the piston seat, the end portion of the top plate is pressed on a cylinder rod of the cylinder, and the connecting rod is clamped inside a backup plate which extends out from the valve body. The container valve of the fire extinguisher is simple and concise in structure and capable of being used independently, thereby lowering manufacturing cost and the maintenance cost of users.
Description
Technical field
The utility model relates to valve body structure, in particular, relates to a kind of valve arrangement for the fire extinguisher container.
Background technique
The fire extinguisher vessel valve structure of using at present (is mainly used in CO
2Container) as shown in Figure 2, when the startup bottle was opened release startup gas, this valve of smooth opening discharged the interior CO of storage bottle group
2Extinguishing medium, extinguishing agent is transported to the zone of protection through valve and pipeline, sprays extinguishing medium by gas tip and puts out a fire.
This class valve arrangement all needs the gas starter just can complete no matter be automatically to start structure or manually boot structure, function singleness, and reliability and stability are poor.It is to puncture blowout disk by starter jointing plug-in strip that this valve is opened, and makes spring reset, thereby discharges CO
2Extinguishing medium.Need change diaphragm when reusing could use, and increased the repair and maintenance difficulty, and product structure is single, must use with other valve combination, and manufacture cost strengthens.
The model utility content
Technical problem to be solved in the utility model be realize a kind of simple in structure, easy to use, repeatedly used fire extinguisher vessel valve structure.
To achieve these goals, the technical solution adopted in the utility model is: a kind of fire extinguisher vessel valve, comprise valve body, and the piston in valve body, the piston connecting end that described piston stretches out valve body is fixed in piston seat, described piston seat one end is fixed on valve body and is fixed with cylinder, the L-shaped connecting end of connecting rod and top board is provided with prizes the hole, wherein interlinking lever end is fixed in the piston seat the other end, top end is pressed on the cylinder column of cylinder, and described connecting rod is stuck in the backup plate that is extended outward by the valve body body.
Described connecting rod is comprised of limited part and joint, and described limited part is vertical with piston seat, and this part contacts with the backup plate face, and described joint is to the piston lopsidedness, and this part end is connected with top board.
Described cylinder is to the piston lopsidedness, and described cylinder angle of inclination is the 10-30 degree.
Described top board is wedge shape, and by itself and the outwards attenuation gradually of connecting rod connecting end.
The outer end of described piston seat and connecting rod joint is provided with the external arc transition.
The utility model has the advantage of that this valve possesses two kinds of functions simultaneously, automatically and manually boot all and can complete, do not need the gas starter on this valve, powerful, use safety, reliable; It is by startup gas push cylinder moving that this valve is opened, and drives the action of top board and connecting rod, makes on piston and moves, thereby discharge the CO2 extinguishing medium.Only need allow cylinder or top board and connecting rod reset when reusing and get final product, repair and maintenance are convenient, and such vessel valve structure is simplified, and can independently use, and has reduced manufacture cost and user's maintenance cost.
Description of drawings
The below is briefly described the content of every width accompanying drawing expression in the utility model specification and the mark in figure:
Fig. 1 is the utility model fire-fighting equipment vessel valve structural representation;
Fig. 2 is old-fashioned fire-fighting equipment vessel valve structural representation;
Mark in above-mentioned figure is: 1, valve body; 2, piston; 3, piston connecting end; 4, cylinder; 5, cylinder column; 6, top board; 7, sled hole; 8, connecting rod; 9, backup plate, 10, piston seat; 11, starter interface; 12, blowout disk; 13, spring.
Embodiment
referring to Fig. 1 as can be known, control conducting by piston 2 in the valve body 1 of fire extinguisher vessel valve, the piston connecting end 3 that piston 2 stretches out valve body 1 is fixed in piston seat 10, piston seat 10 1 ends are to be extended by valve body 1 body, and has elasticity at connection part, piston seat 10 is vertical with piston 2, piston connecting end 3 is fixed on piston seat 10 neutral positions, piston seat 10 the other ends are connected with connecting rod 8 one ends, connecting rod 8 the other ends are connected with top board 6 one ends, piston seat 10 is provided with cylinder 4 with valve body 1 connecting end, its cylinder column 5 identical with piston 2 moving direction (allowing 45 degree with interior differential seat angle), it is capable that top board 6 and connecting rod 8 are L, the outer end of top board 6 is pressed in cylinder column 5 tops of cylinder 4, and connecting rod 8 outsides are stuck in the backup plate 9 that is extended outward by valve body 1 body, backup plate 9 is for having flexible sheet metal.Cylinder 4 promotion cylinder columns 5 move upward like this, promote the related connecting rod 8 of top board 6, piston seat 10 move upward (elasticity that relies on piston seat 10 and valve body 1 fixed end), the final piston 2 that drives outwards moves, Open valve, in order to make the fire extinguisher vessel valve also possess manual opening function, be provided with sled hole 7 at connecting rod 8 and top board 6 connecting ends, can use easily the crowbar Open valve, open theory is identical with cylinder 4 promotions, the just change of power source.
due to the existence that backup plate 9 is arranged, when opening the fire extinguisher vessel valve, the elasticity of dependence backup plate 9 can be with connecting rod 8, piston seat 10 and with its link displacement, reset, wherein connecting rod 8 is comprised of limited part and joint, this limited part is vertical with piston seat 10, thereby guarantee to contact with 9 of backup plates when valve cuts out, can guarantee leakproofness and the stability of 2 sealings of valve closed condition lower piston by both face contacts, piston seat 10 is provided with the external arc transition with the outer end of connecting rod 8 joints, can be so that during open valve, movable smooth and easy, can avoid because opening valve to backup plate 9 extrusion-deformations simultaneously, affecting valve closes and resets.
Smooth and easy for guaranteeing that piston 2 is opened; the stability of valve body 1 and reliability; joint is to piston 2 lopsidedness; and this part end is connected with top board 6; cylinder 4 is to piston 2 lopsidedness; the angle of inclination is the 10-30 degree; top board 6 is wedge shape; and by itself and the outwards attenuation gradually of connecting rod 8 connecting ends; because the motion of piston 2 is to be based upon on the metallic elastic basis of the connecting end of piston seat 10 and valve body 1 and backup plate 9; above-mentioned design can be avoided the metal excessive deformation in the situation that guarantee that piston 2 bars motions put in place, can't recover.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
