Description

Technical Field

[0001] The utility model relates to the field of pressure safety control devices, specifically a bursting valve with detectable output signal that integrates bursting valve functions and state detection functions. It is suitable for container systems that need to accurately monitor and respond to internal pressure changes, such as liquid medicine tanks. Background Art

[0002] Overpressure protection for liquid storage tanks and other containers is crucial in industries like chemical and pharmaceuticals. While traditional burst valves can effectively prevent container rupture due to excessive pressure, they often lack immediate detection and signal feedback mechanisms, making it impossible to notify operators or automatic control systems in a timely manner to take emergency measures.

[0003] Patent application number CN200410155202.X belongs to the technical field of pressure vessel safety equipment and is a safety pressure relief device for fluid overpressure. It includes a bursting disc fixing edge, a bursting disc rigidity zone, a bursting disc connection zone, a bursting cracking zone, an ungrooved area of ​​the bursting disc, and a weakening groove. A bursting disc rigidity zone is provided between the bursting disc fixing edge and the bursting disc connection zone, which serves to limit the caliber of the bursting disc during the bursting process. Through the bursting disc fixing edge, the bursting disc directly or indirectly contacts the edge of the pressure relief hole of the protected container or the pressure relief pipe of the protected container, and can be connected to the protected container by welding, threading, bolt clamping, or other methods. This device overcomes the drawback of existing bursting disc holders, which have limited installation space, and prevents the generation of fragments after the bursting disc explodes, which could block the flow path or cause harm to personnel and equipment. The bursting disc has a simple structure and is safe and practical.

[0004] However, the aforementioned patented technology is unable to immediately send an external alarm signal when the bursting disc ruptures, prompting the entire production line to stop production and eliminate subsequent safety hazards. Therefore, it is particularly important to develop a new bursting valve that can both achieve safe pressure relief and instantly issue an alarm signal. Utility Model Content

[0005] The purpose of this utility model is to provide a burst valve with a detectable output signal to solve the problems raised in the above background technology:

[0006] (1) How to realize the function of sending signals to the external control system at the same time as blasting, thereby improving the response speed and safety of the pressure control system.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A burst valve with detectable output signal;

[0009] Includes valve body assembly, bursting disc and detection assembly;

[0010] The bursting disc comprises a flange body and a bursting disc body. A through hole is opened in the middle of the flange body. The area inside the through hole of the flange body is the bursting cracking area. The bursting cracking area is completely covered by the bursting cracking disc body. The upper side of the bursting cracking area is the pressure relief side. The edge of the bursting cracking disc body is fixedly connected by the flange body.

[0011] The detection assembly includes a magnetic induction switch, a magnetic body, and a connecting spring. One end of the connecting spring is fixedly connected to the flange body of the bursting disc. The other end of the connecting spring extends into the bursting cracking area and is fixedly connected to the magnetic body. The magnetic body is located on the pressure relief side of the bursting disc, and a gap is formed between the magnetic body and the bursting cracking body of the bursting disc.

[0012] The valve seat assembly includes an upper fixed valve seat and a lower fixed valve seat, the upper fixed valve seat and the lower fixed valve seat are detachably connected, the upper fixed valve seat is provided with an upper pressure relief hole corresponding to the bursting cracking area of ​​the bursting disc, the upper fixed valve seat is provided with a mounting hole, the mounting hole is communicated with the upper pressure relief hole, the magnetic induction switch of the detection assembly is installed in the mounting hole of the upper fixed valve seat, the lower fixed valve seat is provided with a lower pressure relief hole corresponding to the bursting cracking area of ​​the bursting disc, and the upper end surface of the lower fixed valve seat is provided with an assembly groove that fits the bursting disc flange body;

[0013] After the upper fixed valve seat of the valve seat assembly is matched with the lower fixed valve seat, the bursting disc is fixedly installed in the chamber formed between the assembly groove of the lower fixed valve seat and the lower end surface of the upper fixed valve seat;

[0014] In the initial state, the magnetic induction switch of the detection component is aligned with the magnetic body, and the magnetic induction switch cooperates with the magnetic body.

[0015] On the basis of the above technical solution, the present invention can also be improved as follows.

[0016] Furthermore, the bursting disc body of the bursting disc is provided with a spherical crown-shaped convex surface facing the pressure relief side.

[0017] Furthermore, the blasting fragment body of the blasting fragment is made of AL3003 material.

[0018] Furthermore, the detection component also supports a spring, the lower end of which is fixedly connected to the flange of the bursting disc, and the upper end of which extends into the bursting cracking area. In the initial state, the upper part of the spring is below the magnetic body.

[0019] Furthermore, the blasting cracking area of ​​the blasting fragment body is 490.625mm 2 The design blasting pressure of the blasting fragments is 0.4MPa.

[0020] Furthermore, the bursting disc further comprises a hand-held portion, one end of which is fixedly connected to the flange body, and the other end of which extends in a direction away from the blasting cracking area.

[0021] After adopting such a structure, in the initial state, when the pressure in the liquid medicine tank is lower than the designed bursting pressure, the magnetic induction switch and the magnetic body remain aligned and work normally, the supporting reed is stably supported, and the liquid medicine tank operates normally.

[0022] When the pressure inside the liquid medicine tank exceeds the designed bursting pressure, the explosive fragments rupture, driving the connecting reed and the magnetic body to swing, and the magnetic body is disconnected from the magnetic induction switch. The magnetic induction switch then sends a burst signal to the control electrical cabinet of the liquid medicine tank, triggering the shutdown protection mechanism of the entire liquid medicine production line.

[0023] The beneficial effects of the detectable output signal burst valve are:

[0024] (1) By integrating the burst valve and signal detection function, instant feedback of pressure anomalies is achieved, improving the safety and automation level of the production line.

[0025] (2) The design of the blasting disc and detection components ensures both the reliability of the blasting and the accuracy of the signal transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The rupture disc 100 includes a flange body 110, a blasting and splitting piece 120, and a hand-held portion 130. A through hole is opened in the middle of the flange body 110. The area inside the through hole of the flange body 110 is the blasting and splitting area. The blasting and splitting piece 120 completely covers the blasting and splitting area. The upper side of the blasting and splitting area is the pressure relief side. The blasting and splitting piece 120 is provided with a spherical crown-shaped convex surface toward the pressure relief side. The edge of the blasting and splitting piece 120 is sealed and fixed to the flange body 110. The blasting and splitting piece 120 of the rupture disc 100 is made of AL3003 material. The blasting and splitting area of ​​the blasting and splitting piece 120 is 490.625mm 2 The design blasting pressure of the blasting and cracking piece 120 is 0.4 MPa. One end of the hand-held part 130 is riveted to the flange body 110, and the other end of the hand-held part 130 extends away from the blasting and cracking area. The setting of the hand-held part 130 facilitates installation and maintenance, and improves the usability of the equipment.

[0039] The detection component includes a magnetic induction switch 210, a magnetic body 220, a supporting spring 240 and a connecting spring 230. One end of the connecting spring 230 is welded and fixed to the flange body 110 of the bursting disc 100, and the other end of the connecting spring 230 extends into the blasting cracking area and is fixed to the magnetic body 220. The magnetic body 220 is on the pressure relief side of the bursting disc 100. There is a gap between the magnetic body 220 and the blasting cracking body 120 of the bursting disc 100. The lower end of the supporting spring 240 is welded and fixed to the flange body 110 of the bursting disc 100, and the upper end of the supporting spring 240 extends into the blasting cracking area.

[0040] The valve seat assembly includes an upper fixed valve seat 310 and a lower fixed valve seat 320, which are detachably connected to each other by bolts. The upper fixed valve seat 310 is provided with an upper pressure relief hole 311 corresponding to the bursting cracking area of ​​the bursting disc 100, and an installation hole 312 is provided inside the upper fixed valve seat 310, which is communicated with the upper pressure relief hole 311.
