For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of chemical storage device, comprise the confession nitrogen valve with confession nitrogen valve admission port and confession nitrogen valve air gate, also comprise the storage device body with admission port, be connected with the admission port of storage device body for the nitrogen valve air gate.The utility model also comprises the breathing valve with breathing valve admission port and breathing valve exhausr port, and also with air extractor duct, the breathing valve admission port is connected with the air extractor duct of storage device body on the described storage device body.
Further, also include waste discharge and take over, described breathing valve exhausr port is taken over waste discharge and is connected.
Further, described breathing valve admission port is connected with the air extractor duct of storage device body by taking over.
Further, the described nitrogen valve air gate that supplies is connected by the admission port of connection pipe with the storage device body.
Further, described storage device body is tank.
Further, described breathing valve is the all-weather anti-explosion fire-retardant breather valve.
After adopting technique scheme, the utlity model has following beneficial effect:
(1) the utility model is provided with breathing valve, when the storage device internal pressure weakens, can replenish atmosphere gas for the nitrogen valve in the trend storage device, when the gaseous tension in the storage device increases to a certain critical value, stops make-up gas for the nitrogen valve; Along with the gradually increase of storage device internal pressure, when pressure reached the pressure release critical value of breathing valve, the beginning pressure release was until pressure stability.So repeatedly, the utility model makes the pressure in the storage device keep stable by regulating pressure.
(2) the utility model also is provided with the waste discharge adapter, and the breathing valve exhausr port is taken over waste discharge and is connected.The breathing valve exhausr port that is arranged so that waste discharge is taken over can be connected with the emission-control equipment of outside, so that it is up to standard or make gas discharging reach again discharging or recycle after the higher more high-quality to discharge the gas processing that contains chemical of storage device.
(3) the storage device body can but to be not limited to be the forms such as cylinder, still, at this preferred tank, convenient processing, use; Adopt the all-weather anti-explosion fire-retardant breather valve to improve breathing valve anti-explosion fire-retardant performance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of A-A among Fig. 1.
Among the figure: 1, for the nitrogen valve, 101, for nitrogen valve admission port, 102, for the nitrogen valve air gate, 2, storage device body, 201, admission port, 202, air extractor duct, 203, discharging opening, 3, breathing valve, 301, the breathing valve admission port, 302, the breathing valve exhausr port, 4, take over, 5, connection pipe, 6, waste discharge takes over, 7, inlet point.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Embodiment
Shown in Fig. 1～2, a kind of chemical storage device comprises for nitrogen valve 1, storage device body 2 and breathing valve 3, also includes adapter 4, connection pipe 5 and waste discharge and takes over 6.Wherein:
---supply nitrogen valve 1 with supplying nitrogen valve admission port 101 and supplying nitrogen valve air gate 102;
---storage device body 2 is with inlet point 7, discharging opening 203, admission port 201 and air extractor duct 202;
---breathing valve 3 comprises breathing valve admission port 301 and breathing valve exhausr port 302;
---be connected with the admission port 201 of storage device body 2 by connection pipe 5 for nitrogen valve air gate 102, breathing valve admission port 301 is connected with the air extractor duct 202 of storage device body 2 by taking over 4; Described breathing valve exhausr port 302 is taken over 6 with waste discharge and is connected.
During normal the use, chemical is entered in the storage device body 2 by inlet point 7, discharges storage device body 2 by discharging opening 203.
When using, the utility model links to each other with the atmosphere gas source of supply for nitrogen valve admission port 101.For realizing the gas shield of chemical, atmosphere gas enters in the storage device body 2 by the nitrogen valve admission port 101 that supplies for nitrogen valve 1, and along with atmosphere gas in the storage device body 2 increases, it is large that its pressure becomes gradually; When the pressure in the storage device increases to a certain critical value, stop make-up gas for the nitrogen valve; When the storage device internal pressure increase to gradually the pressure release critical value of breathing valve the time, breathing valve begins pressure release, until pressure stability.Because breathing valve can be discharged storage device with unnecessary atmosphere gas, so can use the atmosphere gas that flows, keep pressure stability, realize the device that chemical substance stores.
