Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bursting discs, in particular to a vertex groove type bursting disc. Background Art
[0002] A bursting disc, also known as an explosion-proof disc or explosion-proof membrane, can burst at specified temperature and pressure to release the pressure in the container. A bursting disc usually consists of a bursting disc body and a clamping part. The bursting disc body is a component that can burst and relieve pressure at the calibrated bursting pressure and temperature, while the clamp is an auxiliary component that is installed and clamped at the appropriate part of the container. The bursting disc has a simple structure, sensitive and accurate response, and will not leak under normal pressure. It can work reliably in viscous, high temperature, low temperature, corrosive and other environments. It is an ideal safety device for high-pressure containers and is widely used in various industrial fields.
[0003] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: the existing bursting discs have uniform thickness. When the bursting discs are used in medium and low pressure pipelines, in order to enable them to explode and release pressure under the specified air pressure, the thickness is relatively thin after they are manufactured, which leads to high requirements for processing accuracy during the processing of the bursting discs, making the processing of the bursting discs difficult, and prone to air leakage or failure to explode. At the same time, the processed bursting discs are prone to collisions due to the bumps of the transportation vehicle during transportation. Thinner bursting discs are prone to bending and other defects during the collision, which increases the difficulty of transportation. After installation, thinner bursting discs are prone to repeated impacts of the medium and produce metal fatigue, and have poor fatigue resistance. After fatigue occurs, they need to be frequently replaced, causing a lot of inconvenience and economic losses to users. Utility Model Content
[0004] The utility model aims to provide a vertex groove type bursting disc with low processing difficulty, convenient transportation and strong fatigue resistance in view of the defects and shortcomings of the prior art.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vertex groove type bursting disc, comprising a clamping piece for fixing the bursting disc and a bursting disc body arranged on the clamping piece, a weak groove is arranged on the bottom surface of the bursting disc body, a medium high pressure is applied to the bursting disc body, and the pressure is concentrated at the weak groove, so that the bursting disc body bursts under the action of a lower medium pressure, and a bursting guide groove is arranged on the bursting disc body, and the bursting guide groove is a cross-shaped concave groove.
[0006] A further improvement is that the bursting disc body is a spherical cap-shaped thin disc which is reversely arched and arranged on the clamping disc.
[0007] A further improvement is that the weakening groove is an arc-shaped groove with rounded edges.
[0008] A further improvement is that: the blasting guide groove is an arc-shaped concave groove.
[0009] A further improvement is that: the blasting guide groove is an arc-shaped sawtooth groove.
[0010] A further improvement is that the weakened groove is arranged at the center of the bottom surface of the bursting disc body.
[0011] A further improvement is that a reinforcement ring is provided above the clamping piece, a triangular protrusion extending downward is provided on one side of the inner wall of the reinforcement ring, and a spoon-shaped plate extending downward is provided on the other side of the inner wall of the reinforcement ring.
[0012] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: the utility model is provided with a weak groove on the bursting disc body, and then when in use, the pressure of the medium can be concentrated at the weak groove, so that the bursting disc body can burst under the action of a lower pressure, and then when used in medium and low pressure pipelines, the thickness can be increased while maintaining the pressure value required for the bursting, and the thickness of the bursting disc is increased to make the processing easier. At the same time, it is less likely to produce defects due to bumps during transportation, and after being installed in the pressure pipeline, it can withstand more repeated impacts and has better anti-fatigue performance.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments. Embodiment 1:
[0021] See also Figure 1-2 As shown, the technical solution adopted in this specific embodiment is: a vertex groove type bursting disc, comprising a clamping piece 1 for fixing the bursting disc and a bursting disc body 2 arranged on the clamping piece 1, wherein a weak groove 3 is arranged on the bottom surface of the bursting disc body 2, and the medium high pressure is applied to the bursting disc body 2, and the pressure is concentrated at the weak groove 3, so that the bursting disc body 2 bursts under the action of a relatively low medium pressure. When in use, the clamping piece 1 is clamped on the fixed flange of the pressure pipe and locked, and at the same time, the convex part of the bursting disc body 2 faces the direction of higher pressure. When the pressure in the pressure pipe is lower than the bursting pressure, the bursting disc body 2 and the clamping disc 1 seal the pressure pipe to prevent leakage of the medium in the pressure pipe. When the pressure in the pressure pipe is higher than the bursting pressure, the pressure can be concentrated at the weak groove 3, so that the bursting disc body 2 bursts under the action of the lower medium pressure, thereby making the overall thickness of the bursting disc thicker, making the processing easier, and making it less likely to be damaged due to bumps during transportation. After being installed in the pressure pipe, it can withstand more repeated impacts and has better fatigue resistance.
[0022] The bursting disc body 2 is provided with a bursting guide groove, which is an arc-shaped concave groove 41, which is conducive to the bursting disc body 2 to crack along the arc-shaped concave groove 41 when bursting, thereby reducing the debris generated by the bursting, and making the bursting trajectory of the bursting disc body 2 more controllable;
[0023] The bursting disc body 2 is a spherical cap-shaped thin sheet that is reversely arched and arranged on the clamping sheet 1, which is conducive to making the force on the bursting disc body 2 more uniform under low pressure conditions, and avoiding premature bursting due to excessive force on some parts;
[0024] The weak groove 3 is arranged at the center of the bottom surface of the bursting disc body 2, which is conducive to maximizing the reduction of the medium pressure required for bursting;
[0025] A reinforcing ring 10 is also provided above the clamping piece 1, and a triangular protrusion extending downward is provided on one side of the inner wall of the reinforcing ring 10, and a spoon-shaped plate extending downward is provided on the other side of the inner wall of the reinforcing ring 10, which is conducive to making the installation of the bursting disc more convenient and easy to distinguish the front and back sides;
[0026] A control test was set up on a bursting disc with a thickness of 0.17 mm. Under the condition of a temperature of 50°C, the pressure required for the bursting disc body 2 without a weak groove 3 to burst was 2.94 MPa-3.20 MPa, and the pressure required for the bursting disc body 2 with a weak groove 3 to burst was 0.905 MPa-0.961 MPa. The pressure required for bursting was reduced by at least 67%.
[0027] Working principle of this embodiment: When the utility model is used, the clamping piece 1 is clamped on the fixed flange of the pressure pipe and locked, and the raised part of the bursting piece body 2 is faced to the direction of higher pressure. When the pressure in the pressure pipe is lower than the bursting pressure, the bursting piece body 2 and the clamping piece 1 seal the pressure pipe to prevent the medium in the pressure pipe from leaking. When the pressure in the pressure pipe is higher than the bursting pressure, the pressure can be concentrated at the weak groove 3, so that the bursting piece body 2 bursts under the action of the lower medium pressure, thereby making the overall thickness of the bursting piece thicker and making the processing easier. At the same time, it is less likely to produce defects due to bumps during transportation, and it can withstand more repeated impacts after being installed in the pressure pipe, and has better anti-fatigue performance. Embodiment 2:
[0028] See also Figure 1 , 3 As shown, the technical solution adopted in this specific embodiment is different from that in Example 1 in that: the blasting guide groove is a cross-shaped recessed groove 42, which is conducive to making the bursting opening of the bursting disc body 2 cross-shaped, so that there are fewer obstacles to the pressure relief port, the pressure relief speed is faster, and no fragments are generated. The maximum working pressure can reach 90% of the blasting pressure, which is more suitable for working conditions with pulsating pressure.
[0029] Working principle of this embodiment: When the utility model is used, the clamping piece 1 is clamped on the fixed flange of the pressure pipe and locked, and the raised part of the bursting piece body 2 is faced to the direction of higher pressure. When the pressure in the pressure pipe is lower than the bursting pressure, the bursting piece body 2 and the clamping piece 1 seal the pressure pipe to prevent the medium in the pressure pipe from leaking. When the pressure in the pressure pipe is higher than the bursting pressure, the pressure can be concentrated at the weak groove 3, so that the bursting piece body 2 bursts under the action of the lower medium pressure, thereby making the overall thickness of the bursting piece thicker, making the processing easier, and at the same time, it is less likely to produce defects due to bumps during transportation, and after being installed in the pressure pipe, it can withstand more repeated impacts and has better anti-fatigue performance. Embodiment three:
[0030] See also Figure 1 , 4As shown, the technical solution adopted in this specific implementation is different from that of Example 1 and Example 2 in that: the blasting guide groove is an arc-shaped sawtooth groove 43, which is beneficial to make the instantaneous rupture speed of the blasting faster through the arc-shaped sawtooth groove 43, thereby making the pressure relief faster.
[0031] Working principle of this embodiment: When the utility model is used, the clamping piece 1 is clamped on the fixed flange of the pressure pipe and locked, and the raised part of the bursting piece body 2 is faced to the direction of higher pressure. When the pressure in the pressure pipe is lower than the bursting pressure, the bursting piece body 2 and the clamping piece 1 seal the pressure pipe to prevent the medium in the pressure pipe from leaking. When the pressure in the pressure pipe is higher than the bursting pressure, the pressure can be concentrated at the weak groove 3, so that the bursting piece body 2 bursts under the action of the lower medium pressure, thereby making the overall thickness of the bursting piece thicker, making the processing easier, and at the same time, it is less likely to produce defects due to bumps during transportation, and after being installed in the pressure pipe, it can withstand more repeated impacts and has better anti-fatigue performance.
