Abstract
The utility model relates to a safety relief device suitable for on-line checking, which mainly comprises at least two sets of inlet pipelines (1), at least two sets of inlet cut-off valves (2), at least two sets of common safety relief elements (3) (such as relief valves, explosion-proof plates, fusible plugs, etc.,) and a pressure container body (4), wherein The discharge capacity of each set of the safety relief element (3) is bigger than or equal to the safe relief amount of the pressure container when in action. Through simple and novel design, the safety relief device is improved, and the repair, replacement and checking of the safety relief device of the pressure container are realized under the condition that production is not interrupted through on the other hand. The safety relief device has very important significance to departments which emphasize large-scale and continuous production, such as chemical industry, oil refining, light industry and the like.
Description
Technical field
The utility model relates to a kind of safe technology of pressure vessel field, particularly relates to a kind of safe pressure relief device that is suitable for on-line testing.
Background technique
The application of pressurized container in production technology is very extensive, and traditional sectors such as chemical industry, oil refining, light industry, pharmacy, food all be unable to do without pressurized container, and are the necessary key equipments of these departments.Pressurized container is a kind of bearing device.In order to guarantee pressure vessel safety operation, the equipment that prevents is owing to superpressure has an accident, and eliminates except fundamentally taking measures or reduces the various factors that may cause the pressurized container superpressure, and installing safe pressure relief device is a key measure.
Safe pressure relief device can be divided into valve type, breaking type, fusing type and combined by its working principle and structural type.But they are following two problems of ubiquity all.The first, if for a certain reason in the safe pressure relief device certain component lost efficacy, can make whole safe pressure relief device lose original function.For example: the spring of Direct spring loaded safety valve gets rusty, and safety valve can not be opened under the pressure of regulation, can not finish the function of pressure release and protection pressurized container; The second, traditional safe pressure relief device is difficult to realize repairing, replacing and the verification of pressure vessel safety pressure relief device under the situation of breaks in production not, promptly be difficult to repairing, replacing and the verification of canbe used on line pressure vessel safety pressure relief device.
Therefore, engineers and technicians hanker after finding solution to the problems described above always.If can address the above problem well, not only can guarantee the safe operation of pressurized container, and the department that requires extensive continuity to produce for chemical industry, oil refining, light industry etc. can also reduce production costs greatly, improves output, has crucial meaning.
Summary of the invention
The purpose of this utility model is to provide a kind of safe pressure relief device that is suitable for on-line testing, and it can improve the Security of pressurized container, can be implemented in repairing, replacing and the verification of carrying out the pressure vessel safety pressure relief device under the situation of breaks in production not again.
The utility model solves the technological scheme that as above technical problem adopted:
A kind of safe pressure relief device that is suitable for on-line testing, comprise entrance pipe, inlet stop valve, common safety relief element, pressurized container body, its entrance pipe, inlet stop valve, common safety relief element are arranged on the end socket of pressurized container, and are provided with two covers at least respectively.
Described a kind of safe pressure relief device that is suitable for on-line testing, its common safety relief element includes safety valve, burst disk, fusible plug.
Advantage of the present utility model and effect are:
The utility model is owing in the normal using process of pressurized container, have two cover safe pressure relief devices simultaneously at least in work, so can improve the reliability of safe pressure relief device greatly; Need to repair, (as: spring of finding Direct spring loaded safety valve gets rusty, and needs to change spring under the situation of replacing and verification; Perhaps by the national legislation requirement, safe pressure relief device has arrived check-verifying period, in the time of need carrying out verification etc.), then need not to stop to produce and can overlap safe pressure relief device place under repair, replacing and verification respectively, repairing, replacing and verification that promptly can canbe used on line pressure vessel safety pressure relief device each.Like this, solved the problem that safe pressure relief device in the past all must stop production when repairing, replacing and the verification with regard to thorough.Chemical industry, oil refining, light industry etc. are emphasized that the department that extensive continuity is produced has crucial meaning.
Description of drawings
Accompanying drawing is a kind of safe pressure relief device schematic representation that is suitable for on-line testing of the utility model.
Main parts size explanation among the figure: entrance pipe 1, inlet stop valve 2, common safety relief element 3 (as: safety valve, burst disk etc.), pressurized container body 4.
Embodiment
A kind of safe pressure relief device that is suitable for on-line testing mainly comprises entrance pipe, inlet stop valve, common safety relief element (as: safety valve, burst disk, fusible plug etc.), pressurized container body.Entrance pipe, inlet stop valve, common safety relief element are provided with two covers respectively at least; And the discharge amount of every suit safety relief element when action is greater than the safety relief amount that equals pressurized container; Under normal circumstances, every cover safe pressure relief device all is in normal operating condition, and ought need to repair by wherein any cover safe pressure relief device, when replacing or verification, then its inlet stop valve is closed, place under repair, change or verification, repairing, after replacing or the verification, open the inlet stop valve again, this cover safe pressure relief device is come into operation, like this, in the most of the time of pressurized container operation, can guarantee that two covers or the above safe pressure relief device of two covers are in work, improved pressure vessel safety reliability of operation (suppose that wherein a cover is malfunctioning, other safe pressure relief device also can proper functioning) greatly.
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment: referring to shown in Figure 2, the utility model comprises entrance pipe 1, inlet stop valve 2, each two cover and pressurized container body 4 of common safety relief element 3 (as: safety valve, burst disk etc.), is separately positioned on the end socket of pressurized container.In normal productive process, two inlet stop valves 2 all are in the state of unlatching, when the pressure in the pressurized container surpasses the operating pressure of common safety relief element 3 defineds owing to certain abnormal cause, wherein that less cover safe pressure relief device of operating pressure will begin action, pressure in the pressurized container will descend, in the time of in pressure drops to normal range (NR), by the closing automatically of safety relief element 3 (as: flap of safety valve returns seat), or by the people for close the inlet stop valve 2, reach the purpose that returns to normal production.After less that cover safety relief element 3 is changed (as: burst disk etc.) to operating pressure, open its inlet stop valve 2 again, make it recover normal working.When any cover safe pressure relief device needs repairing, replacing and verification, all can realize repairing, replacing and verification by closing its inlet stop valve 2, open inlet stop valve 2 again, make it be in normal working again.Because any cover safe pressure relief device is during repairing, replacing and verification, always there is an other cover safe pressure relief device also to be in normal working, both can effectively prevent pressurized container generation demolition accident, breaks in production has not realized safe pressure relief device is carried out online repairing, replacing and verification again.
