[0002] A reaction kettle is a container for physical or chemical reactions, which is widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine, food, etc. When a chemical reaction is carried out in the reaction kettle, the internal pressure may increase rapidly due to temperature rise, generation of reaction gases, etc. Therefore, a pressure relief safety valve is needed to ensure automatic opening when the pressure exceeds the safety threshold, preventing the reaction kettle from bursting or exploding due to overpressure.

[0003] In the prior art, a shock absorber connected to the four-way safety valve is arranged in the shock absorption cavity of the safety valve. It can not only release pressure when the pressure is higher than the set pressure, but also shock-absorb and reduce noise of the safety valve, reducing noise pollution. However, it cannot gradually release the internal pressure of the reaction kettle, resulting in the service life of the pressure relief safety valve being reduced due to the influence of pressure shock. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a novel pressure relief safety valve for a reaction kettle, aiming to improve the problem that the pressure relief safety valve in the prior art cannot gradually release the internal pressure of the reaction kettle, resulting in the service life of the pressure relief safety valve being reduced due to the influence of pressure shock.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Referring to Figures 1-3 , an embodiment provided by the present utility model: a pressure relief safety valve for a new type of reaction kettle, including a valve seat 1, a connecting sleeve 5 is fixedly connected to the left side of the valve seat 1, a valve body 6 is fixedly connected to the outside of the connecting sleeve 5, an exhaust pipe 7 is fixedly connected to the upper part of the left side of the valve body 6, the exhaust pipe 7 is made of stainless steel, a pressure relief component is arranged inside the valve body 6 for releasing the internal pressure of the reaction kettle, the pressure relief component includes a telescopic column 8, the telescopic column 8 is fixedly connected inside the valve body 6, a spring 9 is arranged outside the telescopic column 8, the spring 9 is limited by the telescopic column 8, one end of the telescopic column 8 away from the valve body 6 is fixedly connected with a sealing block 10, a plurality of exhaust grooves 11 are evenly arranged on the outside of the sealing block 10, both the valve seat 1 and the telescopic column 8 are made of stainless steel, both the connecting sleeve 5 and the valve body 6 are made of high-grade alloy materials, the spring 9 is made of 316 spring steel material, the sealing block 10 is made of polytetrafluoroethylene material, cavities are opened inside both the valve seat 1 and the connecting sleeve 5, the sealing block 10 is slidably connected inside the cavity, the sealing block 10 is installed through the cavity, one end of the spring 9 is fixedly connected with the telescopic column 8, and the other end of the spring 9 is fixedly connected with the sealing block 10.

[0030] Inside the reactor, gas is introduced into the cavity through the intake pipe 2. When the chemical reaction inside the reactor is in progress, the pressure of the gas will change as the reaction proceeds, which may cause an increase in the pressure inside the reactor. To prevent excessive pressure from damaging the equipment, the system is designed with an automatic pressure relief mechanism. As the internal gas pressure rises, the kinetic energy of the gas causes the plug 10 to be pushed, prompting it to slide inside the cavity. The sliding of the plug 10 is not only due to the direct force of the gas but also to optimize the gas discharge path. During this process, the exhaust groove 11 will move accordingly, gradually disengaging from the closed state of the cavity, forming an unobstructed exhaust channel. The gas flows into the valve body 6 through the gradually opening exhaust groove 11. In this part, the valve body 6 plays a key regulatory role and can control the flow rate and flow volume of the gas according to actual needs. This control mechanism is very important and helps to discharge high-pressure gas smoothly and safely, preventing equipment damage or safety accidents that may be caused by sudden pressure release. Once the gas successfully enters the valve body 6, it will pass through a well-designed flow channel and finally release the gas to the external environment through the exhaust pipe 7, achieving effective pressure relief. This pressure relief process must be very rapid and stable to ensure that the equipment operates under normal operating conditions and to guarantee production safety.

[0031] An alarm component is provided on the right side of the valve seat 1 for monitoring and alarming the pressure inside the reactor. The alarm component includes the intake pipe 2. The outer side of the intake pipe 2 is provided with threads to facilitate the installation of the pressure relief safety valve. The intake pipe 2 is fixedly connected to the right side of the valve seat 1. The right side of the inner bottom of the intake pipe 2 is fixedly connected to a pressure detector 3. The upper part of the valve seat 1 is fixedly connected to an alarm lamp 4. The intake pipe 2 is made of stainless steel to ensure the corrosion resistance and strength of the intake pipe 2.

[0032] By setting a reasonable preset value for the pressure detector 3, the system can monitor the pressure change inside the reactor in real time. The preset value is usually determined according to the characteristics of the reaction process and the safety standards of the equipment to ensure that the chemical reaction proceeds within the normal working range. This setting can be adjusted through the operation interface, which is convenient for users to optimize according to different reaction conditions. When the pressure detector 3 real-time monitors that the pressure inside the reactor approaches or exceeds the preset value, it will immediately send an alarm signal. At this time, the pressure detector 3 triggers the alarm lamp 4 to start flashing to attract the attention of the staff and ensure that the staff can react quickly.

[0033] Working principle: When it is necessary to release the internal pressure of the reactor, first set a preset value for the pressure detector 3, and monitor the internal pressure of the reactor through the pressure detector 3. When the pressure detector 3 detects that the internal pressure of the reactor exceeds the preset value, the pressure detector 3 triggers the alarm light 4 to flash and alarm to remind the staff. Under the action of the internal pressure of the reactor, the internal gas of the reactor enters the cavity through the intake pipe 2. The gas pushes the plug block 10 as the pressure changes, causing the plug block 10 to slide inside the cavity. The exhaust groove 11 gradually disengages from the cavity as the plug block 10 slides, and the gas gradually enters the valve body 6 through the exhaust groove 11, and finally the gas is discharged through the exhaust pipe 7 to complete the pressure relief. In this way, the safety valve can gradually release the internal pressure of the reactor, improving the service life of the pressure relief safety valve.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
