Description
Technical field
The utility model relates to the pipeline architectures between a kind of pans and storage tank.
Background technique
In chemical production process, it usually needs setting pans and storage tank will be intermediate for the collection and storage of product
The product collected in tank is transported in the storage tank by pipeline.In large-size chemical production field, the pans and storage
Pipeline between tank is generally longer, in unused situation for a long time, superpressure easily occurs inside pipeline, while both ends valve is difficult
It to open, causes to leak so that damaging equipment, or even generates great accident.
Utility model content
The purpose of the utility model is to provide a kind of pipeline pressure relief devices between pans and storage tank, existing to overcome
There is defect existing for technology.
The pipeline pressure relief device being used between pans and storage tank, including pans, delivery pump, storage tank and pressure release
Component；
Pans, delivery pump and the storage tank passes sequentially through pipeline series connection, sets in the outlet of the delivery pump
There is the first control valve, is equipped with the second control valve in the entrance of the storage tank, described first is arranged in the pressure release component
On pipeline between control valve and the second control valve.
The beneficial effects of the utility model are:
The structure for not changing original device passes through simple pipeline and common accessory, it will be able to ensure safety in production.
Detailed description of the invention
Fig. 1 is for the pipeline pressure relief device structural schematic diagram between pans and storage tank.
Specific embodiment
Referring to Fig. 1, the described pipeline pressure relief device between pans and storage tank, including pans 1, delivery pump 2,
Storage tank 3 and pressure release component；
Pans 1, delivery pump 2 and the storage tank 3 passes sequentially through pipeline series connection, in going out for the delivery pump 2
Mouth 201 is equipped with the first control valve 5, is equipped with the second control valve 6, the pressure release component setting in the entrance 301 of the storage tank 3
On pipeline between first control valve 5 and the second control valve 6；
Preferably, the pressure release component includes: third control valve 7, safety valve 8 and the 4th control valve 9；
The pipeline of the bypass inlet 701 of the third control valve 7 and the first outlet 501 of first control valve 5
It is connected, the bypass outlet 702 of third control valve 7 is connected with the safe valve inlet of the safety valve 8 by pipeline, safety
Valve outlet is connected by pipeline with the circuit entrance 901 of the 4th control valve 9, and the circuit outlet 902 of the 4th control valve 9 passes through pipe
Line is connected with the second entrance 602 of second control valve 6 by pipeline.
Preferably, further include controller and pressure sensor, the pressure sensor, delivery pump 2, the first control valve 5,
Second control valve 6, third control valve 7, safety valve 8 and the 4th control valve 9 are motor-operated control valve, the pressure sensor,
Delivery pump 2, the first control valve 5, the second control valve 6, third control valve 7, safety valve 8 and the 4th control valve 9 respectively with it is described
Controller electrical connection controls the first control valve 5, the second control valve 6, third control according to the pressure signal of pressure sensor
The closing and unlatching of valve 7, safety valve 8 and the 4th control valve 9.
The utility model uses in this way:
In normal use, the third control valve 7 and the 4th control valve 9 in pressure release component are closed, so that in pans 1
Material can smoothly be sent to storage tank 3 by delivery pump 2, when not in use, open 7 He of third control valve in pressure release component
4th control valve 9 can pass through safety valve pressure release when superpressure occurring inside pipeline, it is ensured that safety, avoid due to superpressure and, with
It causes to damage equipment and generates great accident.
