Description

Technical Field

[0001] This utility model relates to the field of valve control technology, and in particular to a novel electromagnetic lock for valve interlocking control. Background Technology

[0002] In the field of industrial automation, valves, as key components of fluid control systems, directly affect the stability of the production process due to their control accuracy and safety. Traditional valve control methods are mainly manual, which is prone to problems such as misoperation, inability to achieve remote control and access control. Manual operation is susceptible to errors due to factors such as fatigue and misjudgment. Especially in the scenario of multi-flow parallel continuous casting production, accidentally closing the crystallizer cooling water valve may lead to overheating of the crystallizer and cause major safety accidents such as physical explosions. At the same time, the lack of remote control and access control mechanisms means that any person can operate the valves, posing a risk of process parameters going out of control due to unauthorized operation.

[0003] Although existing technologies incorporate electromagnetic locks into valve control, most solutions only offer simple energized locking and lack a robust interlocking authorization mechanism. For example, in billet continuous casting scenarios, the inability to dynamically authorize valve operation permissions based on the start / stop status of each flow can easily lead to water waste (valve failure to close in time during stopped flows) or safety hazards (valve misoperation during started flows). Therefore, developing a novel electromagnetic lock for valve interlocking control has significant engineering application value. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a novel electromagnetic lock for valve interlocking control.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a novel electromagnetic lock for valve interlocking control, comprising: an electromagnetic lock body, including a lock shell and a lock core, wherein the lock core includes an iron core and an electromagnetic coil, the electromagnetic coil being wound around the outside of the iron core; a control circuit, including an intermediate relay and a PLC module, wherein the PLC module is connected to the intermediate relay, and the intermediate relay is electrically connected to the electromagnetic coil; a power supply module for supplying power to the electromagnetic coil and the control circuit; and a bracket for mounting the electromagnetic lock body.

[0006] As a further improvement of this utility model: one end of the lock housing is rotatably connected to the bracket via a hinge, and the lock cylinder is located at the other end of the lock housing.

[0007] As a further improvement of this utility model: the lock cylinder is located on the side of the lock shell near the valve.

[0008] As a further improvement of this utility model: the valve is provided with a valve core. The valve core is the operating part of the valve.

[0009] As a further improvement of this utility model, the electromagnetic lock body also includes a protective cover, which is mounted on a bracket. The protective cover and the lock housing form a sealed cavity, and the valve and valve core are enclosed within the sealed cavity formed by the protective cover and the lock housing. By setting the protective cover, which cooperates with the lock housing to surround the valve and valve core, the safety accident of the crystallizer physical explosion caused by the employee accidentally turning off the cooling water supply to the crystallizer during the pouring process is further avoided, and the safety and reliability of valve control are further improved.

[0010] As a further improvement of this utility model: the bracket includes a support rod, a first mounting rod and a second mounting rod, the two ends of the first mounting rod are mounted on the support rod, and the two ends of the second mounting rod are mounted on the support rod.

[0011] As a further improvement of this utility model: one end of the lock housing is rotatably connected to the first mounting rod via a hinge, the lock cylinder is mounted on the second mounting rod, and the lock cylinder is located at the other end of the lock housing.

[0012] As a further improvement of this utility model: the first mounting rod is located at the top of the support rod, and the second mounting rod is located below the first mounting rod.

[0013] As a further improvement of this utility model: the first mounting rod and the second mounting rod are parallel to each other.

[0014] As a further improvement of this utility model, the lock shell is made of steel plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model receives the start or stop signal of pouring through a PLC module and controls the on / off state of the intermediate relay, which in turn controls the on / off state of the electromagnetic coil. By controlling the on / off state of the electromagnetic coil, it controls whether the lock cylinder generates an electromagnetic attraction to the lock shell to hold the lock shell in place. Through interlocking control, the valve opening and closing protection is realized, which effectively improves the safety and reliability of valve control.

[0017] 2. The electromagnetic lock of this utility model can dynamically authorize valve operation permissions according to the start / stop status of each casting cycle, while avoiding water waste (valve not being closed in time for stopped casting cycles) and safety hazards (valve being misoperated for started casting cycles). When the continuous casting machine is in the start state for that casting cycle, the PLC module receives the start signal and controls the intermediate relay to be energized. After the intermediate relay energizes the electromagnetic coil, the lock core generates an electromagnetic attraction to the lock shell, which holds the lock shell in place, preventing the operator from opening the lock shell and avoiding safety accidents caused by accidental valve closure. When the continuous casting machine is in the stop state for that casting cycle, the electromagnetic lock is de-energized, and the operator can open the lock shell to close the valve for that casting cycle, thereby achieving the purpose of saving water.

[0022] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The invention will now be further described with reference to the accompanying drawings and embodiments:

[0023] Please see Figure 1-3 A novel electromagnetic lock for valve interlocking control includes:

[0024] The electromagnetic lock body includes a lock shell 5 and a lock cylinder 6. The lock cylinder 6 includes an iron core and an electromagnetic coil, with the electromagnetic coil wound around the outside of the iron core.

[0025] The control circuit includes an intermediate relay and a PLC module, wherein the PLC module is connected to the intermediate relay, and the intermediate relay is electrically connected to an electromagnetic coil.

[0026] The power module is used to supply power to the electromagnetic coil and control circuitry.

[0027] Bracket 2 is used to install the electromagnetic lock body.

[0028] Bracket 2 is used to install the electromagnetic lock body in the operating position of valve 3; such as Figure 2 and 3 As shown, when the continuous casting machine is in the pouring state, the PLC module receives the pouring signal and controls the intermediate relay to be energized. After the intermediate relay energizes the electromagnetic coil, the lock core 6 generates an electromagnetic attraction to the lock shell 5, which holds the lock shell 5 in place. The operator cannot open the lock shell 5, thus preventing accidental valve closure and avoiding the safety accident caused by accidental valve closure 3.

[0029] like Figure 1As shown, when the continuous casting machine is in a stopped state for that flow, the electromagnetic lock is de-energized. The operator can open the lock housing 5 to close the valve for that flow, thereby saving water.

[0030] The PLC module receives the start or stop signal of pouring and controls the on / off state of the intermediate relay, which in turn controls the on / off state of the electromagnetic coil. By controlling the on / off state of the electromagnetic coil, the system controls whether the lock cylinder 6 generates an electromagnetic attraction to the lock shell 5 to hold the lock shell 5 in place. Through interlocking control, the system protects the valve opening and closing, effectively improving the safety and reliability of valve control.

[0031] Small billet continuous casting machines are generally composed of multi-flow systems. For flows that are not in operation, the cooling water of the crystallizer for that flow needs to be shut off to save energy and media costs. Electromagnetic locks can dynamically authorize valve operation permissions based on the start / stop status of each flow, while avoiding water waste (valve not being closed in time for stopped flows) and safety hazards (valve being misoperated for open flows). During steel casting, the electromagnetic lock is energized by the start signal of a single flow, and the valve is locked through lock housing 5, preventing employees from closing the valve. This avoids the safety accident of employees accidentally shutting off the cooling water supply to the crystallizer, which could cause a physical explosion of the crystallizer.

[0032] In some embodiments, one end of the lock housing 5 is rotatably connected to the bracket 2 via a hinge 7, and the lock cylinder 6 is located at the other end of the lock housing 5, with the lock cylinder 6 located on the side of the lock housing 5 closer to the valve.

[0033] The lock cover 5 is mounted on the bracket 2 via a hinge 7 at one end to enable the opening and closing of the lock cover. Normally, the lock cover 5 covers the lock cylinder 6 and can rotate 180 degrees around the hinge 7.

[0034] In some embodiments, the crystallizer cooling water pipe 1 passes vertically through the platform, and the support 2 is welded to the platform and located in front of the crystallizer cooling water pipe 1.

[0035] In some embodiments, the lock housing 5 is made of steel plate.

[0036] In some embodiments, the valve is provided with a valve core 4. The valve core 4 is the operating part of the valve.

[0037] In some embodiments, the electromagnetic lock body further includes a protective cover (not shown in the figure), which is mounted on the bracket 2. The protective cover and the lock housing 5 form a sealed cavity, and the valve and valve core 4 are covered in the sealed cavity formed by the protective cover and the lock housing 5.

[0038] During the steel casting process, the electromagnetic lock is energized by the single-flow opening signal, and the valve and valve core 4 are locked by the protective cover and lock shell 5, preventing the valve from being closed. This is to avoid the safety accident of the crystallizer being physically exploded due to the employee's accidental operation of turning off the cooling water source of the crystallizer.

[0039] By setting up a protective cover, which works in conjunction with the lock housing 5 to surround the valve and valve core 4, the safety of the crystallizer is further improved by preventing employees from accidentally turning off the cooling water supply to the crystallizer during the pouring process, thus avoiding a physical explosion of the crystallizer.

[0040] In some embodiments, the bracket 2 includes a support rod 8, a first mounting rod 10 and a second mounting rod 11, wherein the two ends of the first mounting rod 10 are mounted on the support rod 8, and the two ends of the second mounting rod 11 are mounted on the support rod 8.

[0041] In some embodiments, one end of the lock housing 5 is rotatably connected to the first mounting rod 10 via a hinge 7, the lock cylinder 6 is mounted on the second mounting rod 11, and the lock cylinder 6 is located at the other end of the lock housing 5.

[0042] In some embodiments, the first mounting rod 10 is located at the top of the support rod 8, and the second mounting rod 11 is located below the first mounting rod 10.

[0043] In some embodiments, the first mounting rod 10 and the second mounting rod 11 are parallel to each other.

[0044] The main functions of this utility model are:

[0045] This invention receives start or stop signals for pouring via a PLC module and controls the on / off state of an intermediate relay, which in turn controls the on / off state of an electromagnetic coil. By controlling the on / off state of the electromagnetic coil, it controls whether the lock cylinder generates an electromagnetic attraction to the lock shell, thus holding the lock shell in place. Through interlocking control, the valve opening and closing protection is achieved, effectively improving the safety and reliability of valve control.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
