Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, and in particular to an electromagnetic pulse type safety valve. Background Technology

[0002] An electromagnetic pulse safety valve is a device that uses electromagnetic force to open and close the valve to ensure the pressure safety of equipment and systems. It generally consists of a valve body, valve core, electromagnetic control component, pressure monitoring component, and control unit. During operation, the pressure monitoring component monitors the system pressure in real time. When the pressure exceeds a preset opening pressure threshold, the control unit energizes the electromagnetic control component, and the electromagnetic force drives the valve core to open the valve and release pressure. When the pressure drops below the reseating pressure threshold, the electromagnetic coil is de-energized, and the valve core resets to close the valve. It features high pressure control accuracy, fast response speed (down to milliseconds), and the ability to achieve intelligent remote control, and is widely used in industrial pipelines, pressure vessels, aerospace, and other fields with stringent pressure safety control requirements.

[0003] Existing magnetic pulse safety valves typically rely on electromagnetic force to control the opening and closing of the valve during use. This requires extremely high accuracy and stability of the electromagnetic signal, but it is not easy to shield against external electromagnetic interference, which can easily lead to current fluctuations, signal distortion, and other problems that affect the normal use of the safety valve. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing technologies, while easy to shield against external electromagnetic interference, are prone to current fluctuations and signal distortion, which in turn affect the normal use of safety valves. Therefore, this invention proposes an electromagnetic pulse type safety valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electromagnetic pulse safety valve, comprising an electromagnetic pulse safety valve structure, a connecting component provided on the side of the electromagnetic pulse safety valve structure, an anti-interference component provided on the outer side of the electromagnetic pulse safety valve structure, the electromagnetic pulse safety valve structure comprising a safety valve body, the anti-interference component comprising an electromagnetic shield, insert blocks symmetrically mounted on the outer side of the electromagnetic shield, a mounting plate provided on the safety valve body, insert slots symmetrically mounted on the outer side of the mounting plate, insert blocks inserted into the insert slots, springs symmetrically connected to the side of the mounting plate, and a limit block connected to one end of the spring.

[0006] Preferably, the connecting assembly includes a connecting pipe and a second flange. A first flange is installed on the outside of the connecting pipe, and a plurality of fastening elements are distributed on the outside of the first flange. The fastening elements are fastened onto the second flange.

[0007] Preferably, the insert block has a limiting hole, and the limiting block is movably installed inside the limiting hole.

[0008] Preferably, a sealing ring is provided on the surface of the first flange, and a limit plate is installed on the outer side of the fastener.

[0009] Preferably, the outer thread of the buckle is threaded with a threaded sleeve.

[0010] Preferably, the second flange has a groove, and the sealing ring is disposed inside the groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by covering the outside of the safety valve body with an electromagnetic shield, it is beneficial to block electromagnetic interference signals from the external environment. The electromagnetic shield reduces the impact of external electromagnetic interference on the internal electronic components of the safety valve body by reflecting and absorbing electromagnetic signals, ensuring the accuracy and stability of electromagnetic signals. This, in turn, enables the electromagnetic pulse safety valve structure to achieve precise opening and closing, ensuring the normal use of the electromagnetic pulse safety valve structure. By inserting the cartridge block into the inside of the mounting plate, the spring is compressed by the squeezing force during insertion. After the cartridge block is inserted, the spring extends, thereby causing the limiting block to be set inside the limiting hole, which is beneficial to provide a certain limiting effect on the cartridge block. At the same time, the operation is convenient and easy to install and remove the electromagnetic shield, which in turn facilitates the maintenance and repair of the safety valve body.

[0013] 2. In this utility model, by connecting the first flange and the second flange, the sealing ring is secured inside the groove, which helps to provide a sealing effect. When the first flange and the second flange are connected, the fastener is secured on the second flange, which helps to provide an auxiliary limiting effect. Subsequently, a threaded sleeve is threadedly connected to the outside of the fastener, which helps to limit the fastener and thus ensures the tightness of the connection between the first flange and the second flange. The limiting plate helps to limit the threaded sleeve, which facilitates the connection between the connecting pipe and the safety valve body. It eliminates the need for a large number of bolts for connection, improves the convenience of operation, shortens the installation time, and thus improves construction efficiency.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-6 As shown, this utility model provides a technical solution: an electromagnetic pulse safety valve, including an electromagnetic pulse safety valve structure 1, a connecting component 2 on the side of the electromagnetic pulse safety valve structure 1, and an anti-interference component 3 on the outer side of the electromagnetic pulse safety valve structure 1. The electromagnetic pulse safety valve structure 1 includes a safety valve body 101, and the anti-interference component 3 includes an electromagnetic shielding cover 301. Insert blocks 302 are symmetrically installed on the outer side of the electromagnetic shielding cover 301. An installation plate 303 is provided on the safety valve body 101, and insertion slots 304 are symmetrically installed on the outer side of the installation plate 303. Insert blocks 302 are inserted into the insertion slots 304. Springs 305 are symmetrically connected to the side of the installation plate 303. One end of the spring 305 is connected to a limit block 306. A limit hole is opened on the insertion block 302, and the limit block 306 is movably installed inside the limit hole.

[0024] In this embodiment, by covering the outside of the safety valve body 101 with the electromagnetic shielding cover 301, it is beneficial to block electromagnetic interference signals from the external environment. The electromagnetic shielding cover 301 can reduce the impact of external electromagnetic interference on the internal electronic components of the safety valve body 101 by reflecting and absorbing electromagnetic signals, ensuring the accuracy and stability of electromagnetic signals, thereby enabling the electromagnetic pulse safety valve structure 1 to achieve precise opening and closing, and ensuring the normal use of the electromagnetic pulse safety valve structure 1. By inserting the cartridge block 302 into the mounting plate 303, the spring 305 is compressed by the squeezing force during insertion. After the cartridge block 302 is inserted, the spring 305 extends, thereby causing the limiting block 306 to be set inside the limiting hole, which is beneficial to provide a certain limiting effect on the cartridge block 302. At the same time, it is convenient to install and remove the electromagnetic shielding cover 301, thereby facilitating the maintenance and repair of the safety valve body 101.

[0025] Example 2: Figures 1-6 As shown, the connecting assembly 2 includes a connecting pipe 201 and a second flange 206. A first flange 202 is installed on the outside of the connecting pipe 201. Multiple fasteners 203 are distributed on the outside of the first flange 202. The fasteners 203 are fastened to the second flange 206. A sealing ring 205 is provided on the surface of the first flange 202. A limit plate 204 is installed on the outside of the fasteners 203. A threaded sleeve 207 is threadedly connected to the outside of the fasteners 203. A groove is opened on the second flange 206, and the sealing ring 205 is disposed inside the groove.

[0026] In this embodiment, by connecting the first flange 202 and the second flange 206, the sealing ring 205 is secured inside the groove, which facilitates a sealing effect. When the first flange 202 and the second flange 206 are connected, the fastener 203 is secured on the second flange 206, which facilitates an auxiliary limiting effect. Subsequently, a threaded sleeve 207 is threaded onto the outside of the fastener 203, which helps to limit the fastener 203, thereby ensuring the tightness of the connection between the first flange 202 and the second flange 206. The limiting plate 204 helps to limit the threaded sleeve 207, which facilitates the connection between the connecting pipe 201 and the safety valve body 101. This eliminates the need for a large number of bolts for connection operations, improves the convenience of operation, shortens the installation time, and thus improves construction efficiency.

[0027] The working principle of this embodiment is as follows: During use, the insert block 302 is first inserted into the mounting plate 303. During insertion, the spring 305 is compressed by the squeezing force. After the insert block 302 is inserted, the spring 305 extends, causing the limiting block 306 to be positioned inside the limiting hole. This provides a certain limiting effect on the insert block 302. Simultaneously, it facilitates the installation and removal of the electromagnetic shielding cover 301. The electromagnetic shielding cover 301, by reflecting and absorbing electromagnetic signals, reduces the impact of external electromagnetic interference on the internal electronic components of the safety valve body 101, ensuring the accuracy and stability of the electromagnetic signal. This, in turn, enables the electromagnetic pulse safety valve structure 1 to achieve precise opening. Opening and closing connects the first flange 202 and the second flange 206, causing the sealing ring 205 to be engaged inside the groove, which helps to provide a sealing effect. When the first flange 202 and the second flange 206 are connected, the fastener 203 is engaged on the second flange 206, which helps to provide an auxiliary limiting effect. Then, the threaded sleeve 207 is threadedly connected to the outside of the fastener 203, which helps to limit the fastener 203, thereby ensuring the tightness of the connection between the first flange 202 and the second flange 206. The limiting plate 204 helps to limit the threaded sleeve 207, which facilitates the connection between the connecting pipe 201 and the safety valve body 101.

[0028] The safety valve body 101 and the electromagnetic shielding cover 301 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the safety valve body 101 and the electromagnetic shielding cover 301 will not be explained in detail.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
