Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pressure vessels, and in particular to an automatic overpressure relief protection cover for pressure vessels. Background Technology
[0002] Pressure vessels are sealed devices that can withstand pressure and are widely used in many fields such as industrial production and daily life.
[0003] When a pressure vessel is overpressurized, it is usually depressurized by a set of automatic relief devices. If the relief devices fail to work due to unexpected factors, the pressure vessel may not be able to depressurize, which may lead to damage to the pressure vessel. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic overpressure relief protection cover for pressure vessels.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic overpressure relief protective cover for a pressure vessel includes a base plate, a cover body connected to the base plate, a storage tank placed inside the cover body, a pressure sensor connected to a flange at one end of the storage tank, a solenoid valve connected to a flange at another end of the storage tank, a cylinder connected to a flange at another end of the storage tank, a rod connected to the cylinder, a ring connected to the rod, a disc movably passing through the rod, a spring connected to one end of the ring, and one end of the spring connected to the disc.
[0007] Preferably, a housing is connected inside the cover, a first pipe is connected to one end of the solenoid valve via a flange, the first pipe is connected through the housing, and a second pipe is connected to one end and the other end of the cylinder, both sets of the second pipes are connected through the housing.
[0008] Preferably, a second sealing ring is provided at one end of the cover where it fits into the storage tank.
[0009] Preferably, a third sealing ring is connected to the connection between the box body and the first tube body and the two sets of second tube bodies.
[0010] Preferably, a door is hinged to one end of the cover.
[0011] Preferably, a valve body is connected to one end of the housing, and the valve body penetrates the cover.
[0012] Preferably, a first sealing ring is connected to one end of the cylinder.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. Through the cooperation between the solenoid valve, pressure sensor and cylinder, when the pressure inside the container is too high, it will push the ring to move. After the ring moves a certain distance, the second pipe is connected to the storage tank to release pressure. At the same time, the pressure sensor will also monitor the pressure inside the container. When it is too high, it will send a signal to the solenoid valve. The solenoid valve will start and the first pipe will be connected to the storage tank to release pressure. To a certain extent, even if one set of pressure relief devices is damaged by accident, the other set of pressure relief devices can also release pressure, which can prevent the container from being damaged due to excessive pressure.
[0015] 2. Through the coordination between the second pipe, the first pipe and the box, the redundant design of the two sets of second pipes avoids the problem of the second pipe being unable to release pressure due to blockage during depressurization. When the first pipe and the second pipe are depressurized, they will transport the gas stored in the storage tank to the box for storage, to be recycled later. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1, referring to Figures 1 to 5 An automatic overpressure relief protective cover for a pressure vessel includes a base plate 1, with a cover 2 connected to the base plate 1. The cover 2 can, to a certain extent, prevent damage to the outer wall of a storage tank 3 caused by external factors. The storage tank 3 is placed inside the cover 2. A pressure sensor 4 is connected to a flange at one end of the storage tank 3. The pressure sensor 4 is connected to a solenoid valve 5 via an external device. The pressure sensor 4 monitors the internal pressure of the storage tank 3. When the pressure is too high, it transmits a signal to the solenoid valve 5. When the solenoid valve 5 is activated, a first pipe 7 connects to the inside of the storage tank 3 for pressure relief. A cylinder is connected to the flange at one end of the storage tank 3. The cylinder 8 is connected to a rod 10, and a ring 11 is connected to the rod 10. A disc 13 is movably passed through the rod 10. A spring 12 is connected to one end of the ring 11. The spring 12 provides a force to move the disc 13 into the storage tank 3. One end of the spring 12 is connected to the disc 13. When the pressure inside the storage tank 3 is too high, it pushes the disc 13 to move. After moving a certain distance, the second tube 9 connects to the inside of the storage tank 3 to release pressure. Through the redundant design of two sets of pressure relief components, the problem of the storage tank 3 being damaged due to excessive pressure is avoided to a certain extent when there is only one set of pressure relief components and the pressure relief components cannot release pressure due to unexpected factors.
[0024] In this embodiment, a housing 6 is connected inside the enclosure 2. A first pipe 7 is flanged at one end of the solenoid valve 5, and the first pipe 7 penetrates the housing 6. A second pipe 9 is connected to both ends of the cylinder 8, and both sets of second pipes 9 penetrate the housing 6. Gas depressurized from the second pipes 9 and the first pipes 7 flows into the housing 6 for storage and later use, thus improving resource utilization to some extent. A second sealing ring 15 is provided at the junction of the enclosure 2 and the storage tank 3 to prevent debris from falling into the enclosure 2. A third sealing ring 18 is connected at the junctions of the housing 6 with the first pipe 7 and the two sets of second pipes 9, improving the sealing performance of the housing 6 to some extent. A door 16 is hinged to one end of the enclosure 2, allowing maintenance of components such as the solenoid valve 5 and pressure sensor 4. A valve 17 is connected to one end of the housing 6, penetrating the enclosure 2. Gas stored in the housing 6 is extracted through the valve 17, processed, and then reinjected into the storage tank 3. One end of the cylinder 8 is connected to a first sealing ring 14, which improves the sealing performance of the cylinder 8 to a certain extent.
[0025] The working principle of this embodiment is as follows: When the pressure inside the storage tank 3 is too high, the pressure sensor 4 transmits a signal to the solenoid valve 5, which then activates. The first tube 7 connects to the inside of the storage tank 3, delivering some of the gas inside the storage tank 3 to the housing 6. Simultaneously, the excessive pressure will push the disc 13 to move. After moving a certain distance, the two sets of second tubes 9 connect to the inside of the storage tank 3, delivering some of the gas inside the storage tank 3 to the housing 6 for recycling. The redundant design of the two sets of second tubes 9 avoids the problem of pressure failure due to blockage of the second tubes 9 to a certain extent. The redundant design of the two pressure relief components also avoids the problem of excessive pressure inside the storage tank 3 due to unforeseen factors when there is only one set of pressure relief components.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
