Abstract
The utility model discloses a nitrogen sealing system, including a plurality of oil storage tanks, confession nitrogen pipeline, let out nitrogen pipeline and breather valve pipeline, a plurality of oil storage tanks connect in parallel in supplying the nitrogen pipeline and let out between the nitrogen pipeline, the breather valve pipeline includes that coordination has person in charge's line of a plurality of oil storage tanks, through two by -pass lines parallying respectively with two breather valves of main pipeline connection, set up the gas valve on the by -pass line, the utility model provides a nitrogen sealing system can improve the problem that the breather valve overhauld in -process, unable continuity of operation.
Description
Technical field
The utility model relates to nitrogen encapsulation technique field, particularly a kind of nitrogen envelope system.
Background technology
Petrol storage tank in food processing factory is nitrogen sealed cans, tank body is connected with nitrogen tube sealing line, for petrol storage tank provides the nitrogen of pressure-fired, guarantee that in tank, crude oil does not contact with air, undergo no deterioration, concrete nitrogen tube sealing line comprises the confession nitrogen pipeline be connected with tank body respectively, let out nitrogen pipeline and breathing valve pipeline, when in petrol storage tank during oil-feed, tank body internal pressure becomes large, remain closed for nitrogen pipeline, let out nitrogen pipeline and open release nitrogen, closed after reaching the normal pressure in tank body, when pumping from petrol storage tank, tank body internal pressure diminishes, let out nitrogen pipeline to remain closed, open for nitrogen pipeline, nitrogen is supplemented in tank body, closed after reaching the normal pressure in tank body, and when oil-feed operation, when letting out the normal pressure that nitrogen circuit cannot maintain in tank body, exhaust opened by breathing valve, reduce pressure, when pumping operation, when required pressure cannot be compensated for nitrogen circuit, air inlet opened by breathing valve, supplementary pressure, thus guarantee that tank body internal pressure is normal, prevent tank body deformed damaged.
But, when breathing valve needs clean and maintenance, need breathing valve pipeline and tank body to cut off, if pass in and out oily operation during this, likely there will be the change of tank body internal pressure, cause tank body to be out of shape, can production capacity be affected if stop operation.
In sum, how to improve in breathing valve maintenance process, cannot the problem of continuous working, become the technical matters that those skilled in the art are urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of nitrogen envelope system, can improve in breathing valve maintenance process, cannot the problem of continuous working.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of nitrogen envelope system, comprises multiple petrol storage tank, for nitrogen pipeline, lets out nitrogen pipeline and breathing valve pipeline, and multiple described petrol storage tank is parallel to described for nitrogen pipeline with describedly let out between nitrogen pipeline, and described breathing valve pipeline comprises:
Be connected with the Trunk Line of multiple described petrol storage tank side by side;
By two breathing valves that arranged side by side two by-pass lines are connected with described Trunk Line respectively;
Be arranged at the gas valve on described by-pass line.
Preferably, described gas valve is manual ball valve.
Preferably, described breathing valve is connected with flame trap.
Nitrogen envelope system provided by the utility model, comprise multiple petrol storage tank, for nitrogen pipeline, let out nitrogen pipeline and breathing valve pipeline, multiple petrol storage tank is parallel to for nitrogen pipeline and lets out between nitrogen pipeline, and breathing valve pipeline comprises the Trunk Line being connected with multiple petrol storage tank side by side, by two breathing valves that arranged side by side two by-pass lines are connected with Trunk Line respectively, be arranged at the gas valve on by-pass line, corresponding breathing valve and nitrogen can be regulated to seal the annexation of system by controlling gas valve, being set up in parallel two breathing valves can by controlling any one connecting system of gas valve choice for use, for the protection of petrol storage tank, when one needs maintenance, then use another, or two breathing valves are regularly used alternatingly, be beneficial to and increase the service life, therefore, such vibrational power flow can ensure the continuous working that nitrogen envelope system can be permanent further, can not be forced to stop work because of the maintenance issue of breathing valve, and affect production capacity.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Incorporated by reference to the structural representation that Fig. 1, Fig. 1 are nitrogen provided by the utility model envelope system.
A kind of nitrogen envelope system provided by the utility model, comprises multiple petrol storage tank 1, for nitrogen pipeline 2, lets out nitrogen pipeline 3 and breathing valve pipeline.
Multiple petrol storage tank 1 is parallel to for nitrogen pipeline 2 and lets out between nitrogen pipeline 3, and wherein breathing valve pipeline comprises: the Trunk Line 41 being connected with multiple petrol storage tank 1 side by side; By two breathing valves 43 that arranged side by side two by-pass lines 42 are connected with Trunk Line respectively; Be arranged at the gas valve 44 on by-pass line 42.
Nitrogen envelope system provided by the utility model, corresponding breathing valve 43 and nitrogen can be regulated to seal the annexation of system by controlling gas valve 44, being set up in parallel two breathing valves 43 can by controlling any one connecting system of gas valve 44 choice for use, for the protection of petrol storage tank 1, when one needs maintenance, then use another, or two breathing valves 43 are regularly used alternatingly, be beneficial to and increase the service life, therefore, such vibrational power flow can ensure the continuous working that nitrogen envelope system can be permanent further, can not be forced to stop work because of the maintenance issue of breathing valve 43, and affect production capacity.
Preferably, breathing valve 43 is connected with flame trap, gas valve 44 is manual ball valve.
Above nitrogen envelope system provided by the utility model is described in detail, apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
