Abstract
The invention discloses an fire extinguisher container valve which comprises a valve body and a piston in the valve body, wherein a piston connecting end of the piston, which extends out of the valve body, is fixed in a piston seat with one end fixed on the valve body and fixed with an air cylinder; prying holes are formed on a connecting rod and an L-shaped connecting end of a top plate, the end part of the connecting rod is fixed at the other end of the piston seat, and the end part of the top plate is pressed on a cylinder rod of the air cylinder; and the connecting rod is clamped into a backing plate extending outwards from the valve body. The container valve has a simplified structure, can be used independently, and reduces the manufacturing cost and maintenance cost for users.
Description
Technical field
The present invention relates to valve body structure, in particular, relate to a kind of valve arrangement for fire extinguisher container.
Background technique
The fire extinguisher container valve arrangement of current use (is mainly used in CO
2container) as shown in Figure 2, when starting bottle and opening release startup gas, this valve of smooth opening, the CO in release storage bottle group
2extinguishing medium, extinguishing agent is transported to zone of protection through valve and pipeline, sprays extinguishing medium put out a fire by gas tip.
No matter this kind of valve arrangement is automatically start structure or manually boot structure, and all need gas starter just can complete, function singleness, reliability and stability are poor.It is puncture blowout disk by starter jointing plug-in strip that this valve is opened, and makes spring reset, thus release CO
2extinguishing medium.Need change diaphragm when reusing could use, add repair and maintenance difficulty, and product structure be single, must use with other valve combination, manufacture cost strengthens.
Summary of the invention
Technical problem to be solved by this invention realizes a kind of structure simply, easy to use, repeatedly used fire extinguisher container valve arrangement.
To achieve these goals, the technical solution used in the present invention is: fire extinguisher container 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, and described piston seat one end to be fixed on valve body and to be fixed with cylinder, connecting rod and the L-shaped connecting end of top board are provided with sled hole, wherein interlinking lever end is fixed on the piston seat the other end, and top end is pressed on the cylinder column of cylinder, and described connecting rod is stuck in the backup plate that extended outward by valve body body.
Described connecting rod is made up of limited part and joint, and described limited part is vertical with piston seat, and this part contacts with backup plate face, and described joint is to piston lopsidedness, and this portions end is connected with top board.
Described cylinder is to piston lopsidedness, and described cylinder angle of inclination is 10-30 degree.
Described top board is wedge shape, and outwards thinning gradually by itself and connecting rod connecting end.
Described piston seat and the outer end of link joint feature are provided with external arc transition.
The invention has the advantages that this valve possesses two kinds of functions simultaneously, automatically and manually boot and all can complete on this valve, do not need gas starter, powerful, use safety, reliable; It is by starting gas push cylinder moving that this valve is opened, and drives top board and connecting rod action, makes piston moves, thus release CO2 extinguishing medium.Cylinder or top board and connecting rod only need be allowed when reusing to reset, and repair and maintenance are convenient, and such vessel valve structure is simplified, and can independently use, and reduces the maintenance cost of manufacture cost and user.
Accompanying drawing explanation
Mark in the content expressed every width accompanying drawing in specification of the present invention below and figure is briefly described:
Fig. 1 is fire-fighting equipment vessel valve structural representation of the present invention;
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, hole is prized; 8, connecting rod; 9, backup plate, 10, piston seat; 11, starter interface; 12, blowout disk; 13, spring.
Embodiment
Known see Fig. 1, conducting is controlled by piston 2 in the valve body 1 of fire extinguisher container valve, the piston connecting end 3 that piston 2 stretches out valve body 1 is fixed in piston seat 10, piston seat 10 one end is extended by valve body 1 body, and at connection part, there is elasticity, piston seat 10 is vertical with piston 2, piston connecting end 3 is fixed on piston seat 10 neutral position, piston seat 10 the other end is connected with connecting rod 8 one end, connecting rod 8 the other end is connected with top board 6 one end, piston seat 10 and valve body 1 connecting end are provided with cylinder 4, its cylinder column 5 identical with piston 2 moving direction (allowing the differential seat angle within 45 degree), top board 6 is capable in L with connecting rod 8, the outer end of top board 6 is pressed in above the cylinder column 5 of cylinder 4, and be stuck in the backup plate 9 that extended outward by valve body 1 body outside connecting rod 8, backup plate 9 is for having flexible sheet metal.Such cylinder 4 promotes cylinder column 5 and moves upward, then the related connecting rod 8 of promotion top board 6, piston seat 10 move upward (elasticity relying on piston seat 10 and valve body 1 fixed end), final drive piston 2 outwards moves, Open valve, in order to make fire extinguisher container valve also possess manual opening function, being provided with sled hole 7 at connecting rod 8 and top board 6 connecting end, crowbar Open valve can being used easily, open theory promotes identical with cylinder 4, just the change of power source.
Owing to there being the existence of backup plate 9, when opening fire extinguisher container valve, the elasticity of dependence backup plate 9 can by connecting rod 8, piston seat 10 and with its link displacement, reset, wherein connecting rod 8 is made up of limited part and joint, this limited part is vertical with piston seat 10, thus guarantee to contact with backup plate 9 when valve cuts out, the leakproofness that valve closed condition lower piston 2 seals and stability can be ensured by both face contacts, piston seat 10 is provided with external arc transition with the outer end of connecting rod 8 joint, when can make open valve, movable smooth and easy, can avoid because opening valve to backup plate 9 extrusion-deformation simultaneously, affect valve and close reset.
Smooth and easy for ensureing that piston 2 is opened; the stability of valve body 1 and reliability; joint is to piston 2 lopsidedness; and this portions end is connected with top board 6; cylinder 4 is to piston 2 lopsidedness; angle of inclination is 10-30 degree; top board 6 is wedge shape; and it is outwards thinning gradually by itself and connecting rod 8 connecting end; motion due to piston 2 is based upon piston seat 10 with on the connecting end of valve body 1 and the metallic elastic basis of backup plate 9; above-mentioned design when guaranteeing that the motion of piston 2 bar puts in place, can be avoided metal excessive deformation, cannot recover.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technological scheme is carried out; or design of the present invention and technological scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
