Abstract
The utility model discloses a vacuum valve box which enables a work site to be orderly and is beneficial to safety production. The vacuum valve box comprises a box body, and at least two sets of vacuum valve structures are installed on the box body. Each vacuum valve structure comprises a vacuum valve and two vacuum joints positioned on a casing of the box body, wherein the vacuum joints comprise a first vacuum joint and a second vacuum joint. Two ports of the vacuum valve are positioned inside the box body and are respectively connected with a first inner pipe and a second inner pipe, one end of the first inner pipe is located inside the first vacuum joint, one end of the second inner pipe is located inside the second vacuum joint, and both an outer wall of the first inner pipe and an outer wall of the second inner pipe are wrapped with at least one layer of thermal insulation blanket. A controlling unit of the vacuum valve is located outside the box body. Through proper setting, the vacuum valve box can arrange each pipeline and each vacuum valve together in a centralized manner, and enables a work site to be orderly and is beneficial to safety production, and can reduces amount of evaporation of cryogenic liquids when the cryogenic liquids flow.
Description
Technical field
The utility model relates to a kind of clack box, especially relates to a kind of vacuum clack box that use in the field that vacuumizes.
Background technique
When extracting cryogenic liquide at present, use the high-vacuum insulation pipeline to come transporting low temperature liquid,, need use vacuum valve that vacuum pump is connected with corresponding pipeline simultaneously to avoid the loss of cryogenic liquide.It is following not enough to adopt aforesaid way to exist: because the production scene often need be extracted the cryogenic liquide in a plurality of equipment out; This just needs to use many high-vacuum insulation pipelines and a plurality of vacuum valve; Can make the production scene disorder like this; Each vacuum valve is not easy to search, and each pipeline is arranged and influenced each other, and is unfavorable for that the safety of producing carries out.
The model utility content
The technical problem that the utility model solves provides a kind of vacuum clack box that the production scene is in good order and help keeping the safety in production that makes.
The utility model solves the technological scheme that its technical problem adopted: the vacuum clack box; Comprise casing; Said casing is provided with at least two cover vacuum valve structures, and said vacuum valve structure comprises vacuum valve and is arranged on first vacuum connect and second vacuum connect on the shell of casing; Two ports of said vacuum valve are positioned at the inside of casing and are connected with first pipe respectively and second pipe; An end of pipe is arranged on the inside of first vacuum connect in said first; An end of pipe is arranged on the inside of second vacuum connect in said second, and the outer wall of pipe all is enclosed with one deck heat insulation layer at least in the outer wall of the said first interior pipe and second; The control device of said vacuum valve is positioned at the outside of casing.
Further be: said first vacuum connect and second vacuum connect all are the flange-type vacuum connect.
Further be: the inside of said casing is vacuum state.
The beneficial effect of the utility model is: through the vacuum clack box is set, can pipeline that be used for join dependency equipment and vacuum valve centralized arrangement be in the same place, make the production scene in good order, the safety that helps producing is carried out.And,, therefore reduced the steam output in the mobile process of cryogenic liquide owing to compact in design, media flow are lacked apart from short and heat transfer.
Description of drawings
Fig. 1 is the schematic representation of the vacuum clack box of the utility model;
Fig. 2 is the annexation schematic representation of pipe and two vacuum connects in vacuum valve and two.
Be labeled as among the figure: vacuum valve 1, control device 11, port one 2, port one 3, the first vacuum connects 2, flange plate 21, connecting tube 22, the second vacuum connects 3, flange plate 31, connecting tube 32, pipe 5 in the heat insulation layer 4, the first, pipe 7 in the heat insulation layer 6, the second, casing 8, shell 81.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As depicted in figs. 1 and 2; The vacuum clack box; Comprise casing 8; Said casing 8 is provided with at least two cover vacuum valve structures, and said vacuum valve structure comprises vacuum valve 1 and be arranged on two vacuum connects on the shell 81 of casing 8 that said two vacuum connects are respectively first vacuum connect 2 and second vacuum connect 3; Two ports of said vacuum valve 1 are positioned at the inside of casing 8 and are connected with first pipe, 5 and second pipe 7 respectively; As shown in Figure 2; Pipe 5 links to each other in the port one 2 of vacuum valve 1 and first; Pipe 7 links to each other in the port one 3 of vacuum valve 1 and second, and an end of the said first interior pipe 5 is arranged on the inside of first vacuum connect 2, and an end of the said second interior pipe 7 is arranged on the inside of second vacuum connect 3; The outer wall of the said first interior pipe 5 is enclosed with at least, and the outer wall of one deck heat insulation layer 4, the second interior pipes 7 all is enclosed with one deck heat insulation layer 6 at least; The control device 11 of said vacuum valve 1 is positioned at the outside of casing 8.The quantity of above-mentioned vacuum valve structure can be 2 covers, and 5 covers or 10 covers etc. can be confirmed according to the actual conditions of production scene.The number of plies of above-mentioned heat insulation layer can be 1 layer, and 2 layers, 4 layers or 8 layers etc. can as required insulation effect and cost design.Above-mentioned heat insulation layer can be processed by the thermoinsulation material of using comparative maturity in the existing technology.
During use and since each vacuum valve all centralized arrangement therefore on same casing, can be convenient to search and install, and each pipeline is owing to be centralized arrangement also, therefore can avoid owing to arrange influencing each other between the pipeline that causes temporarily.And,, therefore reduced the steam output in the mobile process of cryogenic liquide because employing centralized arrangement mode makes media flow lack apart from short and heat transfer.
Above-mentioned vacuum connect can adopt face seal formula vacuum connect or external diameter sealed type vacuum connect, and in order to make designs simplification, versatility is good, and said vacuum connect is preferably the flange-type vacuum connect.As depicted in figs. 1 and 2, first vacuum connect 2 comprises that flange plate 21 and connecting tube 22, the second vacuum connects 3 comprise flange plate 31 and connecting tube 32.As shown in Figure 1, an end of connecting tube 22 links to each other with flange plate 21, and the other end links to each other with the shell 81 of casing.Can make things convenient for relevant device through flange plate and to be connected with pipeline.
On the basis of the above, it is lower to conduct heat when cryogenic liquide is flowed in pipeline, and then makes that the breakage of cryogenic liquide is lower, and the inside of said casing 8 is vacuum state, and just the inside with casing 8 vacuumizes.The implementation of the inner vacuum state of above-mentioned casing 8 has multiple, the casing vacuum valve of internal gas that can be through on casing 8, being provided for extracting casing 8.During use, can extract box house gas, make box house realize vacuum state through the casing vacuum valve.
