Abstract

The utility model relates to a rupture disk technical field especially relates to signal sensor rupture disk, solves the shortcoming that exists among the prior art, including the rupture disk, the rupture disk includes first intermediate layer, second intermediate layer, third intermediate layer, fourth intermediate layer and bolt, first intermediate layer, second intermediate layer, third intermediate layer and fourth intermediate layer pass through bolt fixed connection, and pre-buried there is thin wire between first intermediate layer, second intermediate layer, third intermediate layer and the fourth intermediate layer. Once explosion venting or rupture disk damage occurs, an alarm is sent immediately to remind workers, the workers can be linked with the equipment, the equipment is shut down in time while the alarm is sent, and potential safety hazards are eliminated.

Description

Rupture disk with signal sensor

Technical Field

The utility model relates to a rupture disk technical field especially relates to signal sensor rupture disk.

Background

The non-reclosing pressure relief device consists of a rupture disk (or a rupture disk assembly), a holder (or a supporting ring) and other parts. Under the set blasting pressure difference, when the pressure difference on the two sides of the blasting piece reaches the preset value, the blasting piece acts (breaks or falls off) instantly and releases fluid medium.

The existing common rupture disk only plays a role in pressure relief. After the rupture disk acts, or the fault breaks, the rupture disk can not send a signal to inform workers, and can not be linked with equipment, so that the equipment is stopped in time. Therefore, certain hidden troubles exist.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that exists among the prior art, and the signal sensor rupture disk is provided in signal.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the signal sensor rupture disc comprises a rupture disc body, wherein the rupture disc body comprises a first interlayer, a second interlayer, a third interlayer, a fourth interlayer and a bolt, the first interlayer, the second interlayer, the third interlayer and the fourth interlayer are fixedly connected through the bolt, and a fine wire is pre-buried between the first interlayer, the second interlayer, the third interlayer and the fourth interlayer.

Preferably, both ends of the thin wire extend to the outside of the rupture disk.

The utility model has the advantages that:

1. once the explosion venting or rupture disk is damaged, an alarm is sent out immediately to remind workers.

2. The alarm can be linked with equipment, and the equipment can be shut down in time while the alarm is given out, so that potential safety hazards are eliminated.

Drawings

Fig. 1 is the utility model provides a structural schematic of signal sensor rupture disk.

In the figure: 1 rupture disk, 11 first interlayer, 12 second interlayer, 13 third interlayer, 14 fourth interlayer, 2 thin wires and 3 bolts.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, the rupture disk with the signal sensor comprises a rupture disk 1, wherein the rupture disk 1 comprises a first interlayer 11, a second interlayer 12, a third interlayer 13, a fourth interlayer 14 and a bolt 3, the first interlayer 11, the second interlayer 12, the third interlayer 13 and the fourth interlayer 14 are fixedly connected through the bolt 3, a thin wire 2 is pre-embedded between the first interlayer 11, the second interlayer 12, the third interlayer 13 and the fourth interlayer 14, once the rupture disk is exploded or damaged, an alarm is immediately sent out, a worker is reminded of the rupture disk, the rupture disk can be linked with equipment, the equipment is timely shut down when the alarm is sent out, potential safety hazards are eliminated, and two ends of the thin wire 2 extend to the outside of the rupture disk 1.

In this embodiment, during the use, thin wire 3's both ends lead to the outside of rupture disk 1, thin wire 3's both ends and outside signal equipment and equipment switch intercommunication, under normal conditions, the wire is intact, both ends form a route, when rupture disk 1 pressure release is opened, thin wire 3 receives the impulsive force fracture, original route then becomes open circuit, the route becomes open circuit, it is the signal of a switching value in fact, utilize this signal, then can play the effect of warning and linkage.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
