Description
Technical field
The utility model is related to Domestic garbage treatment equipment technical fields, are supervised more particularly to a kind of safety valve real-time online
Examining system.
Background technology
Safety valve is a kind of safety guard being connected on pressure vessel or pressure pipeline：When in equipment or pipeline
When pressure medium increases to over specified value, by outside system discharge medium come to prevent in pipeline or equipment pressure medium be more than rule
Fixed number value has run important protective effect to personal safety and equipment.
In the prior art, it needs periodically to verify safety valve in the service life of safety valve, it is important in verification
One verification project is is sealed performance detection to safety valve.However, safety valve sealing performance detection is carried out in the prior art
It needs to separate safety valve by installation site, is transported to special equipment inspection center and completes the detection of the parameters such as sealing performance, school
It tests.
To sum up, safety valve sealing performance detection of the prior art carries out under the improper working condition of safety valve, and
Safety valve is difficult to find in time when leaking during normal use, in this way, when leakage situation occurs for safety valve, not only
There are problems that wasting fluid, while the generation of safety accident may be caused.
Utility model content
It is detected for safety valve sealing performance of the prior art set forth above in the improper working condition of safety valve
Lower progress, and safety valve is difficult to find in time when leaking during normal use, in this way, leakage feelings occur in safety valve
During condition, not there is only the problem of waste fluid, while the problem of may cause the generation of safety accident, the utility model provides
A kind of safety valve real time on-line monitoring system, system and method can realize that safety valve carries out safety valve in course of normal operation
Sealing performance monitor on-line, reach safety valve sealing performance monitoring do not influence respective line or pressure vessel normal work,
Find safety valve escape to avoid unnecessary fluid wastage, the purpose for avoiding causing because of fluid leakage safety accident in time.
Safety valve real time on-line monitoring system provided by the utility model is solved the problems, such as by following technical essential：Safety
Valve real time on-line monitoring system, including pressure pipe, the pressure measuring unit being connected on pressure pipe；
The relief pipeline being connected with pressure vessel or pressure pipeline is further included, safety valve is connected on the relief pipeline；
The first block valve is further included, first block valve is series on relief pipeline, and pressure vessel or pressure pipeline
Positioned at the arrival end of the first block valve, safety valve is located at the port of export of the first block valve；
The nozzle of the pressure pipe is connected with relief pipeline, and tie point of the pressure pipe on relief pipeline is located at safety valve
Between the first block valve.
Specifically, when pressure vessel or pressure pipeline work normally, to realize safety valve arrival end and pressure vessel or
The connection of pressure pipeline need to be set as the first block valve and be in opening, and relief pipeline is divided into position by such as the first block valve
The first pipeline section between the first block valve arrival end and pressure vessel or pressure pipeline, positioned at the first block valve port of export and peace
The second pipeline section between full valve arrival end, at this point, the first pipeline section is connected with second pipe.This system exists in realization safety valve escape
When line monitors, the first block valve is closed, at this point, the both ends of the second pipeline section are blocked by the first block valve and safety valve, is taken at this time
Pressure pipe is communicated with the second pipeline section, the pressure value in pressure value reflection second pipe on pressure pipe acquired in pressure measuring unit.
When safety valve No leakage or leakage are in allowed band, data shown in pressure measuring unit are unchanged or in the unit interval
Change rate is less than a certain numerical value；When safety valve escape situation is serious, change rate is big in data unit time shown in pressure measuring unit
In or equal to a certain numerical value.
After the sealing performance monitoring of safety valve is completed, the first block valve is opened, you can so that safety valve and pressure vessel
Or pressure pipeline connection so that safety valve plays over-voltage protecting function.
To sum up, in the prior art, the verification of safety valve carries out primary for general 1 year, can be in safety valve work using this programme
The sealing situation of any time judgement or real-time monitoring safety valve during work；Safety valve real time on-line monitoring disclosed in this programme
In the case where safety valve does not separate installation site, using the internal pressure of pressure vessel or pressure pipeline, peace can be rapidly completed in system
The leakage situation judgement of full valve.In this way, it may be such that safety valve escape monitoring in relevant pressure container or pressure pipeline working condition
Lower progress, achieving the purpose that the sealing performance monitoring of safety valve does not influence respective line or the normal work of pressure vessel；Meanwhile
Since the work of this system can carry out under pressure vessel or pressure pipeline working condition, therefore this programme can find safety valve in time
