Abstract
The utility model relates to a magnetic induction alarm of a rupture disc device, and aims at providing an alarm for the state of a rupture disc device, which is complete in sealing, easy in installation and long in service life. The utility model is realized by the following technical scheme that the magnetic induction alarm comprises a clamping device for fixing a magnetic induction senor and a rupture disc (5), wherein the magnetic induction senor is a pressing spring sensor consisting of a sensor, a locking nut and a pressing spring; a strong-magnetic block (6) and the rupture disc (5) are fixedly connected on a magnetic block component bracket (4) in the clamping device; and the induction end part of the pressing spring sensor for sensing the position changing of the magnetic block on the rupture disc is compressed at one side of the clamping device within a 15mm distance from the strong-magnetic block. The magnetic induction alarm has the advantages that since the magnetic-field change is used as a monitoring mode for the state of the rupture disc, the defects that signals are completely transmitted by solid wires to cause easy leakage and inconvenient installation in the prior art are avoided; the defect that a pressure sensor needs to be contacted with a medium to cause easy corrosion and damage is avoided; and the service life of the sensor is prolonged.
Description
Technical field
The utility model relates to a kind of monitor force security of system annex rupture disk user mode device.
Background technology
In the existing rupture disk user mode monitoring technique; The main entity lead that adopts transmits signal and pressure transducer senses change in pressure transmission signal dual mode; The diaphragm action interrupted chopping signal of lead output when the entity lead transmitted aspect through the rupture disk explosion, reached monitoring rupture disk state.This mode is owing to transmit signal through the entity lead, need carry out encapsulation process to the inside and outside binding site that lead runs through pressure vessel.This encapsulation process method uses encapsulant extruding lead to realize usually, and lead sealing position is owing to pushed by encapsulant, and the easy fracture damage of lead produces the false alarm signal.And revealing appears in sealing point easily.
The working pressure sensor carries out rupture disk condition monitoring mode, and the necessary contact pressure internal tank medium of pressure transducer could pass through container internal pressure change monitoring rupture disk user mode.Because pressure transducer directly contacts with the internal tank medium, when running into the corrosive medium situation, can shorten sensor serviceable life.And pressure transducer connects with pressure vessel and is connected, and connecting portion exists reveals hidden danger.Must apply than high pulling torque pressure transducer is screwed on pressure vessel, through the screw thread crush seal.Not only inconvenient installation, and pressure transducer mounting torque is bigger, causes its damage easily.Pressure transducer changes the rupture disk state of monitoring through experiencing pressure, and after the rupture disk explosion, the pressure vessel interior media is transmitted to the pressure transducer place, and a signal is exported in variation thereby sensor is experienced pressure, indication rupture disk state.But after bursting pressure of bursting sheet internal tank medium was released and finished, and container internal pressure disappears, pressure transducer just can not continue to transmit correct signal and indicate the rupture disk state.
Summary of the invention
The purpose of the utility model is to provide a kind of and seals, installs blasting piece device status alert device easier, longer service life fully.
The purpose of the utility model can reach through following measure.A kind of blasting piece device magnetic induction alarm; Comprise: the fixing clamper of magnetic induction sensor and rupture disk 5; It is characterized in that described magnetic induction sensor is a holddown spring sensor of being made up of sensor, set nut and holddown spring, magnetic block 6 connects firmly on the magnetic patch assembly support 4 in clamper with rupture disk 5; The holddown spring sensor sensing end of magnetic patch change in location is pressed at a distance of magnetic block 15mm with interior clamper one side on the induction rupture disk.
The utility model technical scheme is compared prior art and is had following advantage.
1. seal tight reliable, zero leakage.The utility model is monitored the rupture disk state through the magnetic patch change in location on the magnetic induction sensor induction rupture disk.Because magnetic induction sensor can change across 2～3mm metal level induced field, sensor and pressure system directly do not connect, and do not have leakage point, can accomplish to seal zero leakage fully.So just overcome prior art and transmitted signal, be prone to produce the gap by the entity lead, poorly sealed, the easy defective that lost efficacy of sealing.The leakage hidden danger of the sensor tie point of also having avoided must contact pressure internal system medium causing by pressure transducer.
2. long service life.Because the magnetic induction sensor that adopts can change across certain thickness metal level induced field, has avoided contact pressure internal system medium, especially some corrosive mediums.Thereby improved the serviceable life of sensor.At normal temperature, under the vibrationless operating mode, this magnetic induction sensor device ability operate as normal is more than 2 years.
3. it is easier to change.Magnetic patch assembly and rupture disk are combined into an integral body through spot welding, are convenient to change.
Owing to rupture disk and magnetic patch assembly have been carried out integrated processing, after the rupture disk explosion, also just the magnetic induction assembly have been in place when changing diaphragm.
Description of drawings
In order further setting forth rather than the above-mentioned implementation of restriction the utility model, below in conjunction with accompanying drawing the utility model to be described further, but therefore the utility model not to be limited among the described scope.All these designs should be regarded as content disclosed in the utility model and protection domain.
Fig. 1 is the main cut-open view of the utility model blasting piece device magnetic induction alarm.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural section of magnetic induction sensor member among Fig. 1.
Among the figure: 1. go up clamper, 2. register pin, 3. lower gripper, 4. magnetic patch assembly support, 5. rupture disk, 6. magnetic block, 7. magnetic patch fixedly covers part, 8. holddown spring, 9. set nut, 10. sensor, 11. signal wires.
Embodiment
The blasting piece device magnetic induction alarm that Fig. 1 describes; Comprise: magnetic induction sensor and magnetic patch assembly; And the clamper of fixation of sensor and strong magnetic magnetic patch assembly; Described magnetic induction sensor is one to be made up of sensor, set nut and holddown spring, and this sensor is fixed on the clamper by set nut, is pressed on predefined position by holddown spring sensor sensing end again.During operate as normal, magnetic induction sensor and magnetic patch 6 keeps setpoint distances, and this distance and magnetic induction sensor model, magnetic patch magnetic field power are relevant, generally are set in the 15mm.Rupture disk 5 constitutes pressure system safety attachment blasting piece devices can move explosion under set pressure and temperature, relieving pressure system exception pressure is protected pressure system safety; When the rupture disk explosion; Rupture disk drives the magnetic patch motion, and magnetic patch leaves initial position, and magnetic induction sensor can move to the position of magnetic patch at 0.005 second internal induction; Send a signal, thereby reach the purpose of monitoring rupture disk state.
