Description
Technical field
The utility model is related to explosion-proof valve technical field, more particularly to a kind of new type explosion proof with decompression function in advance
Valve.
Background technology
At present, with the fast development of society, transfer pipeline (pipeline road, air delivering pipeline or be hydraulic pipeline) is made
It is that great contribution has been made in the production practices of the mankind for a kind of important resource transmission mode, it is continuous with transfer pipeline
Increase, the security of transfer pipeline is increasingly valued by people, and in order to ensure the trouble free service of transfer pipeline, people are defeated
Send and explosion-proof valve is added in pipeline, it is well known that when the pressure in transfer pipeline is excessive, explosion-proof valve can start, and then realize
Effect to transfer pipeline flood discharge, therefore explosion-proof valve holds the balance；It is general only when the pressure in pipe is reached in routine use
During one threshold value, explosion-proof valve starts just now, but in practice, above-mentioned threshold value is general than larger, when overpressure reaches threshold value
When nearby, pipeline subjects huge security threat safely, if pipeline is under high pressure operations for a long time, to whole
Then there is huge potential safety hazard in pipeline.So, design and develop and a kind of overpressure can be entered according to the size of overpressure
The explosion-proof valve that row shifts to an earlier date the either local pressure release of pressure release seems it is particularly important.
Utility model content
The technical problems to be solved in the utility model is：A kind of explosion-proof valve is provided, the explosion-proof valve being capable of basis
The size of overpressure, carries out shifting to an earlier date pressure release, and then ensure the safe operation of pipeline to overpressure.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
A kind of explosion-proof valve, including：It is connected to the explosion-proof valve body (2) on transfer pipeline (3)；The explosion-proof valve body (2)
Including an entrance, one outlet and a venting；
The arrival end of the explosion-proof valve body (2) is provided with the pressure sensor of detection transfer pipeline (3) interior pressure information,
A circular hole is opened up on the transfer pipeline (3), protection sleeve pipe is welded with the circular hole；Detection probe (1) insertion should
In protection sleeve pipe；The outer wall that the detection probe (1) of the pressure sensor penetrates transfer pipeline (3) gos deep into transfer pipeline (3)；
Pressure relief pipe is provided with the transfer pipeline (3), magnetic valve (4) is installed on the pressure relief pipe；The pressure sensor
Signal output terminal electrically connected by data wire with the comparison terminal of comparator, the lead-out terminal and magnetic valve of the comparator
(4) control terminal electrical connection.
Preferably, the utility model additionally uses following technical scheme：
Further：The venting is by guiding pipeline to be connected with return line；It is provided with the guiding pipeline anti-
Plate bursting and flame screen.
The utility model has the advantages and positive effects of：
By using above-mentioned technical proposal, pressure sensor can in real time be detected to the pressure in pipeline, and will inspection
Survey result send to comparator, be provided with advance on the comparison terminal of comparator and compare threshold value, compare threshold value be slightly less than it is explosion-proof
The pressure value that plate is born；When the pressure in pipeline approaches the threshold value of explosion-proof valve startup, and then reach when comparing threshold value, then compare
Triggering level is exported compared with device, under the startup of the triggering level, magnetic valve, which is opened, carries out pressure release, when the pressure in pipeline persistently increases
Plus, when finally beyond threshold value (i.e. the startup pressure value of explosion-proof valve), then pressure release is realized by explosion-proof valve.

Fig. 1 is the structural representation of the utility model preferred embodiment.
Wherein：1st, detection probe；2；Explosion-proof valve body；3rd, transfer pipeline；4th, magnetic valve；5th, bursting diaphragm；6th, return line.
Embodiment
For utility model content of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and
Accompanying drawing is coordinated to describe in detail as follows：
Referring to Fig. 1, a kind of explosion-proof valve, including the explosion-proof valve body 2 being connected with transfer pipeline 3；The explosion-proof valve body 2 includes
One entrance, one outlet and a venting,
The arrival end of the explosion-proof valve body 2 is provided with the pressure sensor of pressure information in detection transfer pipeline 3, the pressure
The outer wall that the detection probe 1 of sensor penetrates transfer pipeline 3 gos deep into transfer pipeline 3；The specific installation process of detection probe 1
For a circular hole is opened up on transfer pipeline 3 first, protection sleeve pipe is inserted in the circular hole, then protection sleeve pipe is welded in
On transfer pipeline 3, detection probe 1 is inserted out of protection sleeve pipe, then entered the gap between detection probe 1 and protection sleeve pipe
Row pours sealing；Pressure relief pipe is provided with the transfer pipeline 3, magnetic valve 4 is installed on the pressure relief pipe；The pressure
The signal output terminal of force snesor is electrically connected by data wire with the comparison terminal of comparator, the lead-out terminal of the comparator
Electrically connected with the control terminal of magnetic valve 4.Because comparator and magnetic valve are the electronic product of comparative maturity, therefore herein not
Excessive repeat is carried out to its specific structure and operation principle again.Comparator in this preferred embodiment is preferably univoltage
The LM311 comparators of comparative type；Pressure sensor is selected according to the liquid property inside transfer pipeline, such as liquid
