Abstract
The utility model provides a full cross-section valve membrane of electricity explosion valve punctures knife tackle spare, includes uide bushing, conical head body, side puncture membrane blade, and the one end fixed mounting of conical head body is on the uide bushing, and side puncture membrane blade sets up on the head conical surface of conical head body along circumference interval. When the guide sleeve is moved leftwards to puncture the valve diaphragm, the side film puncturing blade can puncture the valve diaphragm into a plurality of umbrella surface spliced sub-diaphragms along the radial direction from the center of the valve diaphragm, all the sub-diaphragms are directly lifted towards the right side under the action of the high-pressure liquid fire extinguishing agent, and the liquid with the full cross section can flow out, so that the problem that the large flow of the full cross section cannot be released after the film puncturing blade punctures the valve diaphragm in the prior art is solved, the fire extinguishing agent can pass through the low-damping full cross section when the electric explosion valve is opened, and the side film puncturing blade is one of key points for improving the fire extinguishing efficiency of the fire suppression device for the battery box.
Description
Technical Field
The utility model relates to an electric explosion valve in battery box fire suppression device. In particular to a membrane pricking knife of an electric explosion valve.
Background
At present, an electric explosion valve used in a battery box fire suppression device is shown in figure 1, and comprises a valve body 1, a one-way inflation valve 2, a pressure relief valve 3, a pressure gauge 4, a fire extinguishing agent injection head 5 and an electric explosion assembly 6, wherein the valve body 1 is provided with a container connecting end 11, an electric explosion end 12, an inflation pressurizing end 13 and a release end 14, the inflation pressurizing end 13 of the valve body 1 is provided with the one-way inflation valve 2 and the pressure gauge 4, the electric explosion assembly 6 is arranged at the electric explosion end 12, the container connecting end 11 is hermetically connected with a fire extinguishing bottle, in the electric explosion assembly 6, a guide sleeve 61 provided with a puncture knife 63 presses a spring 62 between the guide sleeve 61 and a film pressure sleeve 64 under the action of air pressure at the moment after an electric explosion head 60 is ignited and detonated, and because the existing puncture knife 63 is of a tubular type knife slope structure, when the puncture knife 63 breaks the valve 65, when the guide sleeve 61 moves to the limit position to the left, the membrane puncturing knife 63 of the tubular bevel knife structure can only puncture half of the valve membrane 65, so that the fire extinguishing agent in the fire extinguishing bottle can only be released and flows out along half of the section of the inner hole of the tube body of the membrane puncturing knife 63, and the fire extinguishing agent cannot be guaranteed to flow along the whole section of the tube body of the membrane puncturing knife 63. Although the side wall long hole 66 is arranged on the membrane puncturing knife 63, the large flow can not be released in the whole section, and the fire extinguishing efficiency is directly influenced.
In order to solve the defects in the prior art, the applicant provides the low-damping large-flow-release electric explosion valve, after the electric explosion head is ignited and detonated, the fire extinguishing agent can be sprayed and released from the whole section, and the defects that the air inflation is not convenient and the air inflation or filling efficiency is low in the prior art are overcome.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a knife tackle is punctureed to full cross-section valve membrane of low damping of electricity explosion valve, it enables to puncture the membrane sword and punctures the valve diaphragm full cross-section, and the valve diaphragm punctures along radially being punctured the membrane sword from the center promptly, presses the area fire extinguishing agent to push open and flow to the valve diaphragm full width, can solve the problem of proposing in the above-mentioned background art at present.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a full cross-section valve membrane of electricity explosion valve punctures knife tackle spare, characterized by: the film puncturing blade comprises a guide sleeve, a conical head pipe body and side film puncturing blades, wherein one end of the conical head pipe body is fixedly installed on the guide sleeve, and the side film puncturing blades are arranged on a head conical surface of the conical head pipe body at intervals along the circumferential direction.
Furthermore, the number of the side film pricking blades is more than or equal to three.
Still further, the number of the side film pricking blades is six.
Further, the taper of the head conical surface of the conical head pipe body is 60-150 degrees.
Furthermore, the head of the cone head pipe body is a frustum cone.
The utility model has the advantages that:
the utility model improves the prior tubular inclined plane knife structure film pricking knife into a cone head radial multi-knife structure, the conical surface of the closed part of the conical head pipe body is provided with side film pricking blades at intervals along the circumferential direction, the other end of the conical head pipe body is fixedly arranged on the guide sleeve, thus, when the guide sleeve moves leftwards to puncture the valve diaphragm and the guide sleeve moves leftwards to the limit position, the side puncture blade fixed on the conical surface of the head can puncture the valve diaphragm into a plurality of umbrella surface splicing sub-diaphragms from the center of the valve diaphragm along the radial direction, under the action of high-pressure liquid fire extinguishing agent, all the sub-diaphragms are directly lifted to the right side, so that the full-section liquid can flow out, therefore, the problem that the large flow of the whole cross section cannot be released after the membrane piercing knife pierces the valve membrane in the prior art is solved, the fire extinguishing agent can pass through the whole cross section with low damping when the electric explosion valve is opened, and the fire extinguishing device is one of the key points for improving the fire extinguishing efficiency of the fire suppression device of the battery box.
