Description

Technical Field

[0001] The utility model is designed in the field of fire safety technology, in particular to a novel explosion-type electromagnetic valve starting valve device. Background Art

[0002] The electromagnetic start valve is an actuator installed on the fire extinguishing gas storage tank. In the gas fire extinguishing system, after a fire occurs, the fire extinguishing system usually starts the fire extinguishing gas storage device through a traditional electromagnetic start valve to release the fire extinguishing gas. The start-up method is generally to rely on electromagnetic force or manual pressure to start. However, in large-scale energy storage projects, if a fire occurs in the energy storage device, the fire is difficult to control, or even if the fire extinguishing system fails due to fire or other reasons, the gas fire extinguishing system cannot be automatically activated. At this time, it is necessary to manually press the fire extinguishing gas start valve to perform the fire extinguishing operation. Human intervention at this time is extremely dangerous, so the existing technology needs to be innovated.

[0003] In the prior art, when the automatic fire extinguishing system fails, human intervention is required to start the fire extinguishing, which is very risky; the fire extinguishing can only be triggered by the automatic fire extinguishing system. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a novel explosion-type solenoid valve starting valve device, which has multiple triggering modes and can be automatically triggered without human intervention under certain conditions, and the various triggering conditions do not interfere with each other.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A novel explosion-type solenoid valve starting valve device, comprising

[0007] A protective shell, wherein the middle part thereof has a tubular structure, and the lower end of the tubular structure has a limiting structure;

[0008] a striker assembly, a needle-shaped member at its lower portion, the striker assembly being mounted in the tubular structure;

[0009] An elastic support structure is installed in the tubular structure near the lower end, and two ends of the elastic support structure abut against the limiting structure and the striker assembly respectively;

[0010] a core propellant charge mounted in the tubular structure and disposed adjacent to a top portion of the firing pin assembly;

[0011] A plugging structure is installed in the tubular structure, and the tubular structure is plugged at the upper end of the tubular structure;

[0012] The induction heat-sensitive wire is connected to the core propellant. The induction heat-sensitive wire is used to ignite the core propellant after being heated, and the core propellant combustion pushes the needle-shaped member at the bottom of the firing pin assembly to extend out of the tubular structure.

[0013] Preferably, the limiting structure is an annular step structure arranged on the inner wall of the tubular structure and adjacent to the lower end.

[0014] Preferably, the elastic supporting structure is a spring.

[0015] Preferably, the manual hammer is provided with a latch hole, in which a safety latch is detachably inserted for preventing the manual hammer from being accidentally triggered.

[0016] Preferably, the striker assembly has a latch hole, in which a safety latch is detachably inserted for preventing the striker assembly from being accidentally triggered.

[0017] Preferably, an upper end cover and a lower end cover are respectively installed at the top end and the lower end of the protective shell, and both the upper end cover and the lower end cover are provided with a through hole structure corresponding to the position of the tubular structure in the protective shell.

[0018] Preferably, there is a transfer charge between the core propellant and the induction heat-sensitive wire.

[0019] Preferably, the blocking structure is a manual hammer, which can move in the tubular structure along the extension direction of the tubular structure.

[0020] Preferably, there is a cavity between the outer wall of the protective shell and the tubular structure, in which there is an electromagnetic coil. The tubular structure also has an electromagnetic hammer for cooperating with the electromagnetic coil. The electromagnetic hammer is installed at the upper end of the firing pin assembly. When the electromagnetic coil is triggered, it can move through the electromagnetic hammer and push the needle-shaped part at the lower part of the firing pin assembly out of the tubular structure.

[0021] The beneficial effects of using the utility model are:

[0022] The novel explosive solenoid valve starting valve device has a core propellant arranged in a protective shell, and an induction thermal wire is arranged corresponding to the core propellant. When the induction thermal wire is triggered, the core propellant can be ignited, the core propellant burns rapidly, and explodes in the limited space within the tubular structure of the protected object, which can drive the needle-shaped part at the bottom of the firing pin assembly to extend out of the tubular structure, thereby completing the explosive starting valve.

[0023] The solenoid valve starting valve device is also provided with a manual hammer, a solenoid coil and an solenoid hammer. When necessary, it can be started by manually triggering the valve or by remotely controlling the valve. These two starting methods do not conflict with the explosion-type starting valve and do not interfere with each other. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0032] In order to solve the problem that when the automatic fire extinguishing system fails in the prior art, human intervention is required to start the fire extinguishing, which is risky, and the fire extinguishing can only be triggered by the automatic fire extinguishing system, such as Figure 1 As shown, this embodiment proposes a new type of explosion-type solenoid valve starting valve device. Specifically, the new type of explosion-type solenoid valve starting valve device includes a protective shell 10, the middle part of the protective shell 10 has a tubular structure, and an upper end cover 9 and a lower end cover 14 are respectively installed at the top and the bottom of the protective shell 10. The upper end cover 9 and the lower end cover 14 are both provided with a through hole structure corresponding to the position of the tubular structure in the protective shell 10. There is a step structure at the lower end of the hole structure of the lower end cover 14 for matching the spring, and an annular protrusion is provided at the lower end of the lower end cover 14 corresponding to the hole structure. The outer ring surface of the annular protrusion has a mounting thread 15, and the mounting thread 15 is used to install the new type of explosion-type solenoid valve starting valve device as a whole with the external threaded hole structure. There is also a step structure at the top of the hole structure of the upper shell to limit the manual hammer 4 from detaching from the hole structure.

[0033] The manual hammer 4 has a latch hole, in which a safety latch 8 for preventing the manual hammer 4 from being accidentally triggered is detachably inserted. The striker assembly 7 has a latch hole, in which a safety latch 8 for preventing the striker assembly 7 from being accidentally triggered is detachably inserted. When the safety latch 8 is inserted into the latch hole, Figure 1 As shown, the firing pin assembly 7 and the manual hammer 4 cannot be triggered, which is convenient for transportation and storage. Figure 2 As shown, the striker assembly 7 can be driven out of the lower end cover 14 at any time.

[0034] like Figure 3 As shown, in the connected cavity formed by the hole structure and the tubular structure, there are a spring striker assembly 7, a blasting hammer 6, a core propellant 11, an electromagnetic hammer 3 and a manual hammer 4 from bottom to top. There is also a cavity between the outer wall of the protective shell 10 and the tubular structure, in which there is an electromagnetic coil 1, and in the tubular structure there is also an electromagnetic hammer 3 for cooperating with the electromagnetic coil 1. The electromagnetic hammer 3 is installed at the upper end of the striker assembly 7. When the electromagnetic coil 1 is triggered, it can move through the electromagnetic hammer 3 and push the needle-like member at the lower part of the striker assembly 7 out of the tubular structure.

[0035] like Figure 4 As shown, the spring is installed in the tubular structure near the lower end, and the two ends of the spring respectively abut the limiting structure and the firing pin assembly 7; the core propellant 11 is installed in the tubular structure and is arranged adjacent to the top of the firing pin assembly 7; there is a pyrotechnic powder 12 between the core propellant 11 and the inductive thermistor 13, and the inductive thermistor 13 is connected to the core propellant 11 through the pyrotechnic powder 12, and the inductive thermistor 13 is used to ignite the core propellant 11 after being heated, and the combustion of the core propellant 11 pushes the needle-shaped part at the lower part of the firing pin assembly 7 out of the tubular structure.

[0036] like Figure 5 As shown, the manual hammer 4 can also be pressed manually, and the manual hammer 4 drives the electromagnetic hammer 3 to move downward, overcoming the spring resistance so that the needle-like structure at the lower end of the striker assembly 7 extends out of the lower shell.

[0037] The specific structures of the various components in this embodiment are as follows.

[0038] Electromagnetic coil 1: The main body of this component is wound with copper wire. When 24V DC is passed through, it can cooperate with the electromagnetic hammer 3 to generate 90N / m of power, impact the firing pin module, and achieve the starting purpose.

[0039] Wiring socket 2: This component provides an interface for the power input of the electromagnetic coil 1, which is convenient for installation and wiring.

[0040] Electromagnetic hammer 3: This component is a magnetic iron cylindrical component, which cooperates with the electromagnetic coil 1 to impact the striker assembly 7 to achieve the starting purpose.

[0041] Manual hammer 4: This component is an actuator for manual quick start in an emergency state. A safety pin 8 is installed on the upper part. In an emergency, the safety pin 8 can be pulled out and the hammer can be pressed to achieve the starting purpose.

[0042] The fire transfer component 5 is composed of an inductive thermistor, a gunpowder 12 and a charge-carrying platform. The inductive thermistor (customizable length) enters the component from the outside and winds around the gunpowder 12. When the set combustion temperature is reached near the thermistor, the thermistor burns and continues to ignite the gunpowder 12, thereby igniting the core propellant 11 on the top of the explosive hammer 6.

[0043] Explosive hammer 6: This component is the core component of the explosive pneumatic valve, which consists of a hammer shell, a hammer hollow core, and a core propellant 11 filled in the core. When the gunpowder 12 of the fuse module is ignited by an external fire source, the core propellant 11 is ignited through the ignition hole of the explosive hammer 6 shell, and then the explosion of the core propellant 11 drives the hammer core to impact the firing pin module, thereby achieving the starting purpose.

[0044] Strike pin assembly 7: This assembly consists of a striker, a return spring, a striker carrier, and a safety latch 8. When the hammer triggers the impact, this component serves as the main actuator to activate the fire extinguishing facility.

[0045] Safety latch 8: This component is installed on the manual hammer 4 connecting rod and the firing pin module respectively, and is mainly used as a safety protection device during equipment installation.

[0046] Upper end cover 9 and lower end cover 14: These components provide protection for the entire device and facilitate transportation and installation.

[0047] Protective housing 10 and connecting screws: This component provides protection for the entire device and facilitates transportation and installation.

[0048] This new explosion-type solenoid valve starting valve device continues the simplicity of structure and easy installation of previous solenoid starting valve devices, while increasing the reliability of the device, avoiding delays in fire extinguishing due to fire extinguishing system failures and high on-site risks when a fire occurs, thereby reducing the economic and casualty losses caused by the fire.

[0049] The novel explosive solenoid valve starting valve device has a core propellant 11 in the protective shell 10, and an induction thermosensitive wire 13 is arranged corresponding to the core propellant 11. When the induction thermosensitive wire 13 is triggered, the core propellant 11 can be ignited, and the core propellant 11 burns rapidly and explodes in the limited space in the tubular structure of the protected object, which can drive the needle-shaped part at the bottom of the firing pin assembly 7 to extend out of the tubular structure, thereby completing the explosive starting valve.

[0050] The solenoid valve starting valve device is also provided with a manual hammer 4, an electromagnetic coil 1 and an electromagnetic hammer 3. When necessary, it can be started by manually triggering the valve or by remotely controlling the valve. These two starting methods do not conflict with the explosion-type starting valve and do not interfere with each other.

[0051] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
