Abstract

This utility model relates to an electromagnetic drive connector, which includes a connector body, a starting diaphragm, a supplementary core, a piercing needle, and a starting hose connector. One end of the connector body is screwed to the threaded mounting interface of the main release pipe, and the other end is screwed to the electromagnetic drive device. The side of the connector body is provided with a starting hose connector for connecting to the starter of the selector valve through the starting hose. The starting diaphragm is provided inside the connector body and is pressed and fixed to the connector body by the supplementary core in a screwed manner. This utility model combines electrical signal drive with release pressure to form a linkage between the electromagnetic drive device and the selector valve starter, which can support remote and linkage control.

Description

Technical Field

[0001] This utility model relates to the field of inert gas fire extinguishing, specifically to an electromagnetic drive connector. Background Technology

[0002] In existing gas extinguishing systems, the selection valve is activated by two traditional modes: pneumatic activation and emergency manual activation. Pneumatic activation relies on high-pressure gas to drive the selection valve to open, which has the characteristics of rapid response and strong power, ensuring timely release of extinguishing agent when a fire occurs. Emergency manual activation serves as a backup method when pneumatic activation fails, allowing manual operation of the mechanical device to open the selection valve. Its advantage is that it does not rely on electricity or gas sources, and is simple and reliable.

[0003] Traditional solutions are mainly pneumatic or manual, relying on independent drive air sources and complex pipelines, resulting in high system integration and maintenance costs. They are difficult to connect to fire alarm or linkage platforms to achieve remote and linkage control. At the same time, the consistency and repeatability of startup are poor, and the response time is greatly affected by the operator, the site environment and pipelines. The reliability is low in unattended or nighttime scenarios, and there is a risk of misoperation, hesitation or misalignment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an electromagnetic drive connector to solve the technical problems of the current traditional solution which is mainly pneumatic or manual, relies on independent drive air source and complex pipeline, has high system integration and maintenance costs, is difficult to connect to fire alarm or linkage platform to achieve remote and linkage control, has poor start-up consistency and repeatability, is affected by operator, on-site environment and pipeline, has large fluctuations in response time, has low reliability in unattended or nighttime scenarios, and has the risk of misoperation, hesitation or misalignment.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design an electromagnetic drive connector, which includes a connector body, a start-up diaphragm, a core, a needle, and a start-up hose connector;

[0006] One end of the connector body is screwed to the threaded mounting interface of the release main pipe, and the other end is screwed to the electromagnetic drive device. The side of the connector body is provided with a starting hose connector for connecting to the starter of the selector valve through the starting hose.

[0007] The connector body is provided with an activation diaphragm, which is used to close the air passage between the main release pipe and the activation hose connector when not activated. The activation diaphragm is pressed and fixed to the connector body by a core screw.

[0008] The needle is slidably disposed in the central hole of the core, and its length is adapted to the top rod of the electromagnetic drive device.

[0009] Preferably, one end of the main release pipe is connected to a pipe joint, and the top of the pipe joint is connected to a selector valve through a pipe body. A pneumatic starter is provided on the side of the selector valve.

[0010] Preferably, an O-ring seal is provided between the core and the connector body.

[0011] Preferably, an O-ring seal is provided at the sliding contact between the needle and the core.

[0012] Preferably, the starter hose connector is installed at the side threaded mounting interface of the connector body.

[0013] Preferably, the needle is located upstream of the activation diaphragm and maintains a preset gap with it in the non-activated state to avoid damage to the activation diaphragm under transportation or vibration conditions.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model integrates electrical signal drive and pressure release transmission to achieve linkage from electromagnetic drive device to selector valve starter, supports remote / linkage control, has consistent start response and high repeatability, and reduces the uncertainty caused by manual intervention.

[0016] 2. This utility model releases pressure by electromagnetically driving membrane rupture and conduction, eliminating the need for a driving gas cylinder group and its matching valves and pipelines. This reduces the number of connection points and seals, shortens the installation path, reduces leakage risk and maintenance workload, and helps to shorten the construction and commissioning cycle and reduce system costs.

[0017] 3. This utility model uses a connector to be used with an electromagnetically driven container valve, resulting in a more compact system structure, a clearer and simpler layout, and improved system reliability and maintainability. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1: Electromagnetic drive connector, see Figures 1 to 3 The electromagnetic drive connector 6 includes a connector body 61, a start-up diaphragm 62, a filler core 63, a piercing pin 64, and a start-up hose connector 65.

[0024] One end of the connector body 61 is screwed to the threaded mounting interface of the release main pipe 1, and the other end is screwed to the electromagnetic drive device 5. The side of the connector body 61 is provided with a starting hose connector 65, which is used to connect with the starter of the selector valve 2 through the starting hose 4.

[0025] The connector body 61 is provided with a start diaphragm 62, which is used to close the air passage between the main release pipe 1 and the start hose connector 65 when not activated. The start diaphragm 62 is pressed and fixed inside the connector body 61 by the supplementary core 63 in a screw connection.

[0026] The needle 64 is slidably disposed in the center hole of the core 63, and its length is adapted to the push rod of the electromagnetic drive device 5 so that a gap is maintained between the end of the needle 64 and the activation diaphragm 62 in the non-activated state to avoid accidental puncture; when the electromagnetic drive device 5 is activated, the push rod pushes the needle 64 to puncture the activation diaphragm 62, thereby establishing a gas passage from the main pipeline 1 to the activation hose connector 65.

[0027] The electromagnetic drive connector 6 is installed between the main release pipe 1 and the electromagnetic drive device 5, and is connected to the starter 3 of the selector valve 2 through the lateral start hose 4 interface. The start diaphragm 62 is screwed and pressed into the body 61 by the core 63. The core is sealed in the body 61 with an O-ring. The needle 64 slides in the center of the core 63 and matches the length of the push rod of the electromagnetic drive device 5 to avoid accidentally puncturing the diaphragm when not in operation. Thus, the gas passage between the main release pipe 1 and the start hose 4 is closed when not in operation. When the system receives the fire extinguishing start command, the electromagnetic drive device 5 is energized, the push rod is pushed down and pushes the needle 64 to puncture the start diaphragm 62, so that the release pipe and the drive gas passage of the selector valve 2 starter are connected. Then the agent bottle container valve opens, and inert gas enters the main release pipe 1. The pressure is transmitted to the selector valve 2 starter 3 through the connector and the start hose 4, thereby driving the selector valve 2 to complete the start.

[0028] For details, see Figure 3 One end of the main release pipe 1 is connected to a pipe joint, and the top of the pipe joint is connected to a selector valve 2 through the pipe body. A pneumatic starter 3 is provided on the side of the selector valve 2.

[0029] For more details, see Figure 3 An O-ring seal is provided between the core 63 and the connector body 61.

[0030] Further, see Figure 3 An O-ring seal is provided at the sliding contact point between the needle 64 and the core 63.

[0031] It is worth noting that, see Figure 1 The starter hose connector 65 is installed at the threaded mounting interface on the side of the connector body 61.

[0032] It is worth noting that, see Figure 3 The needle 64 is located upstream of the activating diaphragm 62 and maintains a preset gap with it in the non-activated state to avoid damage to the activating diaphragm 62 under transportation or vibration conditions.

[0033] When using the electromagnetic drive connector, when the system receives the fire extinguishing start command, the electromagnetic drive device 5 is energized, the push rod is pushed down and pushes the piercing needle 64 to pierce the start diaphragm 62, so that the release pipeline and the drive gas path of the selector valve 2 starter are connected. Then the agent bottle container valve opens, the inert gas enters the release main pipeline 1, and the pressure is transmitted to the selector valve 2 starter through the connector and the start hose 4, thereby driving the selector valve 2 to complete the start.

[0034] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
