Technical field
The utility model belongs in the electronic chemical product production process closed container and uses the safety protection technique field, is specifically related to a kind of safety guard of closed container.
Background technology
In chemical process, in the particularly ultrapure electronic chemical product production process, because it requires high for product purity, production process is normally carried out in a closed container, then along with the variation of internal tank and ambient pressure difference, for example all can make the running of equipment excess load when superpressure or negative pressure, can cause flat or crack in the equipment, equipment can be damaged even scrap when serious.In order to protect container not to be damaged when the superpressure or not inhaled during in negative pressure flatly, on container, set up a water sealed tank usually.Water sealed tank promptly is a little container, and top is a cylindrical shell, and the centre is established dividing plate and is divided into two, and is connected with U-bend in the bottom, dress water in the U-bend.When container inner pressure rises, the one end water surface descends and the rising of the other end water surface, during along with the continuation rising of pressure and above setting value, liquid level drops to U-bend turn of bilge summit, force other end liquid level to enter water sealed tank top cylindrical shell, because the cylindrical shell sectional area is far longer than the U-bend sectional area, liquid enters the lifting height of cylindrical shell and can ignore.At this moment, gas rises from U-bend turn of bilge summit and enters atmosphere by cylindrical shell, reaches the purpose of decompression protection container.Otherwise when vacuum reached limit value in the container, ambient atmosphere entered container from U-bend turn of bilge summit by cylindrical shell, reached the purpose of make-up gas protection container.The deficiency of its existence: 1. the liquid in the water sealed tank is carried away, and the Field Force can not in time find, thereby make container can't reach airtight problem; 2. at north of china in winter, there is the problem of congealing in the liquid in the water sealed tank; 3. overflow from sealing liquid owing to concentration difference makes the medium in the container, cause the wasting phenomenon of resource.
At above-mentioned existing problems, be necessary the safety guard structure of existing closed container is improved, technical scheme described below produces under this background.
Summary of the invention
The purpose of this utility model is the safety guard that a kind of closed container will be provided, and it can not only protect container not to be damaged when pressure exceeds limit value, also can avoid the loss of medium; Simultaneously, simple in structure, the equipment less investment need not manually-operated, can realize Automatic Control.
The purpose of this utility model reaches like this; a kind of safety guard of closed container; comprise that tank body and cap seal constitute on tank body and between the two the cover that is tightly connected; described tank body is provided with discharge nozzle and liquid level gauge; described discharge nozzle is provided with hydraulic pump and control valve; described cover is provided with charging aperture and Pressure gauge; be characterized in: on described cover, also have additional and be used for the breather valve that communicates with jar chamber; blowdown pipe and tube connector; described blowdown pipe is provided with magnetic valve; described tube connector is provided with pressure controller; be provided with power contact head in the described pressure controller; be used for the diaphragm and the spring that cooperate and can move up and down with described power contact head; one end of one termination external power source of described magnetic valve; one end of another termination power contact head of magnetic valve, the other end of another termination external power source of power contact head.
In a specific embodiment of the present utility model, the material of described diaphragm is preferably stainless steel.
In another specific embodiment of the present utility model, on the described diaphragm gasket seal is installed.
In another specific embodiment of the present utility model, described breather valve is a malleation safety valve.
The utility model is because after adopting said structure; saved the water sealed tank structure in the prior art; by breather valve be located at the magnetic valve on the blowdown pipe and be located at pressure controller on the tube connector and come air pressure in the automatic regulating tank body; when the jar internal gas pressure rises; breather valve can be opened automatically; reach the purpose of decompression protection container; when the jar internal gas pressure descends and produce negative pressure; by pressure controller control magnetic valve; make magnetic valve connect external power source and open valve on the blowdown pipe; extraneous ultrapure air or inert gas enter in the container by blowdown pipe, reach the purpose of make-up gas protection container.Thereby the utility model can not only effectively protect container not to be damaged when pressure exceeds limit value, guarantees the usage safety performance of storage tank, increases the service life, and also can avoid the loss of medium; Simultaneously, simple in structure, the equipment less investment need not manually-operated, can realize Automatic Control.
