Abstract
The invention discloses a protective gas feeding device of chemical equipment. The protective gas feeding device of the chemical equipment comprises a storage tank, a first valve, a second valve and a sealing structure, wherein protective gas is stored in the storage tank, the first valve is connected to the storage tank, the second valve communicating with the first valve is connected to the chemical equipment, and the sealing structure is installed between the first valve and the second valve. The sealing structure comprises a first sleeve fixedly connected with the first valve and a second sleeve fixedly connected with the second valve; and materials of the first sleeve and the second sleeve are PFA and PTFE correspondingly, the first sleeve is sleeved with the second sleeve, and the outer surface of the first sleeve is matched with the inner surface of the second sleeve in a sealed mode. According to the protective gas feeding device of the chemical equipment, a sealing form that the first sleeve made of PFA is combined with the second sleeve made of PTFE is adopted by the sealing structure, sealing performance is good, mounting and dismounting are convenient and quick.
Description
Technical field
The present invention relates to a kind of protective gas feedway of chemical industry equipment.
Background technology
Protected, it is necessary to be passed through the protective gas such as inert gas for some special chemical products and chemical process.In the prior art; storage tank that the feedway of chemical industry equipment protective gas mainly contains protective gas including internal memory, the first valve being connected on the storage tank, the second valve being connected on chemical industry equipment, are connected between the first valve and the second valve by pipeline.Sealed by filling filler or being realized by mechanical sealing member between pipeline and valve, there is the deficiencies such as filler easily abrasion and leakage, dismounting difficulty.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art, there is provided a kind of protective gas feedway of improved chemical industry equipment, its good airproof performance, easy to loading and unloading.
To solve above technical problem, the present invention is adopted the following technical scheme that：
A kind of protective gas feedway of chemical industry equipment, the storage tank of protective gas is contained including internal memory, it is connected to the first valve on storage tank, the second valve communicated with the first valve and the sealing structure being arranged between the first valve and the second valve are connected on chemical industry equipment, wherein, the sealing structure includes the first sleeve being fixedly connected with the first valve, the second sleeve pipe being fixedly connected with the second valve, first sleeve, the material of the second sleeve pipe is respectively PFA and PTFE, first sleeve is plugged in two sleeve pipes, and the outer surface of first sleeve coordinates with the inner surface sealing of the second sleeve pipe.
According to a preferred aspect of the present invention, the second sleeve pipe coordinates with first sleeve phase screw thread, can be specifically that the inner surface of the second sleeve pipe sets screw thread, during sealing, first sleeve is inserted in the second sleeve pipe.
Due to the implementation of above technical scheme, the present invention has the following advantages that compared with prior art：
The seal form that sealing structure of the invention is combined using the first sleeve of PFA materials and the second sleeve pipe of PTFE materials, good seal performance is easy to loading and unloading, quick.
Brief description of the drawings
The present invention will be further described in detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the schematic front view for being mounted with partial crystallization groove of the invention；
Fig. 2 is enlarged drawing at A in Fig. 1；
Wherein：1st, the second valve；2nd, sealing structure；20th, first sleeve；21st, the second sleeve pipe；3rd, cell body.
Specific embodiment
Referring to Fig. 1, Fig. 2, protective gas feedway is installed on the cell body 3 of partial crystallization groove and is passed through protective gas with to cell body 3.Storage tank that protective gas feedway contains protective gas including internal memory, the first valve (not shown) being connected on storage tank, it is connected to the second valve 1 communicated with the first valve on cell body 3 and the sealing structure 2 being arranged between the first valve and the second valve 1.Sealing structure 2 specifically include be fixedly connected with the first valve and material for PFA plastics first sleeve 20 be fixedly connected with the second valve 1 and material for PTFE (polytetrafluoroethylene (PTFE)) the second sleeve pipe 21.The inner surface of the second sleeve pipe 21 is provided with screw thread, and first sleeve 20 is plugged in second sleeve pipe 21, and mutually sealing coordinates between them.
The seal form that sealing structure of the invention is combined using the first sleeve of PFA materials and the second sleeve pipe of PTFE materials, compared with packing seal structure, not only sealing property is more excellent, be not susceptible to wear and tear and reveal, and its assembly and disassembly more facilitates.
The present invention is described in detail above, but the invention is not restricted to the embodiments described.The equivalent change or modification that all Spirit Essences of the invention are made, should all cover within the scope of the present invention.
