Abstract
A compressed air storage tank decompression valve having an explosion-proof function comprises a safety valve body, wherein a movable tappet is arranged in the safety valve body; the movable tappet is connected to the safety valve body through an elastic support component; an elastic metal membrane is arranged at the lower end of the movable tappet; a metal contact piece I and a metal contact piece II are arranged above the elastic metal membrane; a decompression groove is formed on the safety valve body; and the metal contact piece I and the metal contact piece II are connected into a pre-warning circuit. The compressed air storage tank decompression valve is simple and compact in structure, reliable in operation and good in safety performance. With the compressed air storage tank decompression valve, the total quality of the storage tank is reduced and the cost is saved; and the application range of the compressed air storage tank decompression valve is wide.
Description
Technical field
The utility model relates to a kind of safety relief valve, especially relates to a kind of compressed air reservoir Decompression valves with explosion prevention function.
Background technique
Existing compressed air reservoir normally increases its intensity by the wall thickness that increases gas holder.When the pressure in the gas holder raise because of reasons such as gasifying, be heated, if step-down in time, it was stable to keep the gas holder internal pressure, tends to cause blasting.At present, the step-down to gas holder is to lean on the driver manually to realize mostly; In addition,, be usually used in the engineering construction place because compressed air reservoir is of many uses, work under bad environment, temperature is high, and vibration is big, so for the rising of gas holder pressure, must there be the excellent prevention measure anti-explosion safety aspect.
Chinese patent 95230377.9 discloses a kind of nothing and has leaked complete opening type gas cylinder Decompression valves; Though this valve has the explosion-proof and auto-reset function of releasing pressure automatically; If but only as if flammable pressurized gas are excreted the safety that gas holder has been protected gas holder, blemish in an otherwise perfect thing be not have warning function.Especially, when using as the gas cylinder Decompression valves, the long-time leakage of inflammable gas but can not be reported to the police, and causes when not known all the time, certainly will bring huge blast to threaten to surrounding environment.
The model utility content
In order to overcome the above-mentioned defective that existing technology exists, the utility model provides a kind of Safety performance the high compressed air reservoir Decompression valves with explosion prevention function.
The technological scheme of the utility model is: it comprises Safety valve body; Be provided with removable tappet in the Safety valve body; Removable tappet is connected with Safety valve body through elastic support member, and removable tappet lower end is provided with the elastic metallic diaphragm, and elastic metallic diaphragm top is provided with two Metal Contact sheet I, Metal Contact sheet II that do not join each other; Safety valve body is provided with pressure relief groove, and Metal Contact sheet I and Metal Contact sheet II are connected in the early warning circuit.
Further, the preferred spring of elastic support member.
Further, said Safety valve body should be " ∩ " shape.
Further, said early warning circuit comprises power supply, beacon, buzzer, and power supply, beacon, buzzer are electrically connected successively.
The utility model is installed on the gas holder import and export.
When gas pressure surpassed safety margin, early warning circuit began to report to the police, and reminds the manual step-down of driver;
If the driver is not at the scene, when perhaps alarm system is made mistakes, along with the continuation rising of pressure, safety relief valve will be opened automatically, realize releasing pressure automatically.
The utility model is simple in structure, compact, reliable operation, and Safety performance is good.And, using the utility model, the wall thickness of gas holder can suitably reduce, and gross mass can descend to some extent, the economical with materials cost.
The utility model not only can be used as the compressed air reservoir safety relief valve, also can be used as the gas cylinder Decompression valves.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation;
Fig. 2 is the early warning circuit structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
With reference to Fig. 1, present embodiment comprises Safety valve body 1, is provided with removable tappet 4 in the Safety valve body 1; Removable tappet 4 is connected with Safety valve body 1 through elastic support member 5; Elastic support member 5 is a spring, and removable tappet 4 lower ends are provided with elastic metallic diaphragm 2, and elastic metallic diaphragm 2 tops are provided with two Metal Contact sheet I8-1, Metal Contact sheet II8-2; Safety valve body 1 is provided with pressure relief groove 3, and Metal Contact sheet I8-1 and Metal Contact sheet II8-2 are connected in the early warning circuit.
With reference to Fig. 2, early warning circuit comprises power supply 9, beacon 10, buzzer 11, and power supply 9, beacon 10, buzzer 11 are electrically connected successively.
The utility model is installed on the gas holder import and export.
When the pressure in the gas holder raise, elastic metallic diaphragm 2 began distortion, and deformation extent raises with pressure and increases; When pressure increased to a certain degree, elastic metallic diaphragm 2 was deformed to position 7, made mutual originally Metal Contact sheet I8-1 that does not join and Metal Contact sheet II8-2 under the effect of the elastic metallic diaphragm 2 after the distortion; Realize conductive communication; At this moment, early warning circuit is started working, and beacon 10 lights; Buzzer 11 also begins to pipe, and reminds the driver to realize the manual pressure release to gas holder.
If the driver can not accomplish manual pressure release not at the scene at this moment, along with the pressure in the gas holder continues to rise, on continuing, moves removable tappet 4, and high pressure air begins releasing pressure automaticallies through pressure relief groove 3; After the gas holder internal pressure dropped to safety value, under the effect of elastic support member 5, removable tappet 4 moved down, and again pressure relief groove 3 is sealed up, and the pressure of keeping in the gas holder is in below the safety value.
Claims (4)
1. have the compressed air reservoir Decompression valves of explosion prevention function, comprise Safety valve body, it is characterized in that; Be provided with removable tappet in the Safety valve body; Removable tappet is connected with Safety valve body through elastic support member, and removable tappet lower end is provided with the elastic metallic diaphragm, and elastic metallic diaphragm top is provided with two Metal Contact sheet I, Metal Contact sheet II; Safety valve body is provided with pressure relief groove, and Metal Contact sheet I and Metal Contact sheet II are connected in the early warning circuit.
