The invention relates to a stopping device for special loop overhauling and debugging. An upper cover (1) and a lower cover (2) are connected in a butting mode to be installed on two sides of the outer wall of a pipeline (12), a connection rod (3) is inserted into a fixed seat (13) assembled by the upper cover (1) and the lower cover (2), an opening pin (4) is inserted in a through hole in the end portion of the connection rod (3), independent space is formed on the outside of the pipeline, an injection port (14) is arranged in the upper cover (1), and an inlet cover (11) is installed on the injection port (14). The device changes the traditional way that media in a loop need to be discharged or a valve is utilized to stop medium flowing during loop overhauling and debugging. The device is a medium stopping device simple in structure, reliable in operation, convenient to install and applicable to various pipe diameters.
Description
Technical field: the present invention relates to extraordinary loop maintenance debugging occluding device.
Background technique: when circuit system need to overhaul debugging, common way is to discharge the medium in loop or utilize valve blocking-up media flow, and these two kinds of methods all exist drawback for the complicated loop of transmission special media.First, if the medium in loop has contaminativity, need to consider recovery, processing and the recycling of medium when discharge, this has increased financial cost virtually, has extended the repair cycle, also has the hidden danger of befouling environment simultaneously; Secondly, if rely on the media flow in valve blocking-up loop completely, for complicated circuit system, valve quantity will be very huge so, and this has not only increased construction and the maintenance cost of circuit system, has also increased the leakage hidden danger in loop simultaneously.
Summary of the invention:
The object of the invention is in complicated loop system, to flow and propose a kind of safe and reliable, efficient solution easily for blocking medium in Practical Project, thereby avoid increasing because discharging medium or the cost that too much valve causes being installed.The object of the invention is openly a kind of extraordinary loop maintenance debugging occluding device that utilizes characteristic blocking-up medium that medium low temperature solidifies to flow in loop.Technological scheme of the present invention is: a kind of extraordinary loop maintenance debugging occluding device, upper cover (1) and lower cover (2) abutting joint are in pipeline (12) outer wall both sides, connecting rod (3) is inserted in the equipped fixed base (13) of upper cover (1) and lower cover (2), connecting rod (3) end through-hole mounting cotter pin (4), the first right end cap (5), the second right end cap (6) is by bolt (9), nut (10) puts together on the right-hand member of upper cover (1) and lower cover (2), the first left end cap (7), the second left end cap (8) is by bolt (9), nut (10) puts together on the left end of upper cover (1) and lower cover (2), device forms an independently space outside pipeline, upper cover (1) is with inlet (14), on inlet (14), be installed into lid (11).
The occluding device principle explanation for maintenance debugging of extraordinary loop:
As shown in Figure 2, the maintenance debugging of extraordinary loop can multiple unit processes with occluding device, be installed on the pipeline outer wall of target pipeline section both sides, outside pipeline, form two independently enclosed spaces, this device need to be according to different calibers, select the first right end cap (5), the second right end cap (6), the first left end cap (7) and second left end cap (8) of different inner diameters size.
As shown in Figure 2, inject liquid nitrogen by the maintenance debugging of extraordinary loop with the inlet (14) on occluding device upper cover (1) top, then close access cover (11), on the pipeline that this device is installed, form topical hypothermia, utilize the be cooled temperature of pipeline section of infrared temperature measurement gun measurement, keep the solidifying point of temperature lower than pipeline internal medium, after the medium in pipeline herein solidifies, medium just can not flow between two devices, now just can pipeline be overhauled or be debugged.Complete after maintenance debugging, device is removed, utilize ambient temperature that the medium in pipeline is melted, recover flowing state.
The maintenance debugging of extraordinary loop is succeeded in developing with occluding device, and the efficiency of construction that makes engineering pipeline maintenance and debugging is improved greatly.
The invention has the beneficial effects as follows:
(1) what the present invention proposed utilizes characteristic blocking-up medium mobile method in loop that medium low temperature solidifies to belong to pioneering, need to be by traditional method emptying loop medium or dependence valve blocking-up media flow when the method has changed loop maintenance debugging, the valve quantity that plays the effect of blocking-up medium while significantly reducing loop maintenance debugging, reduces construction and the maintenance cost in loop.
(2) the maintenance debugging of the extraordinary loop of the present invention adopts the structural type of two halves formula half arc upper cover and lower cover, semicircle end cap with occluding device, the advantage such as that this structure has is low to installation environment requirement, do not destroy loop original structure, installation process is simple, meets actual demands of engineering.
(3) the present invention can choose according to the outside dimension of return the end cap of corresponding internal diameter, is applicable to multiple caliber loop, can form tandem product.

Embodiment
As shown in Figure 1, a kind of extraordinary loop maintenance debugging occluding device, upper cover 1 and lower cover 2 abutting joints are in pipeline 12 outer wall both sides, connecting rod 3 is inserted in upper cover 1 and the equipped fixed base 13 of lower cover 2, as shown in Figure 3, connecting rod 3 end through-hole mounting cotter pins 4, the first right end cap 5, the second right end cap 6 is by bolt 9, nut 10 puts together on the right-hand member of upper cover 1 and lower cover 2, the first left end cap 7, the second left end cap 8 is by bolt 9, nut 10 puts together on the left end of upper cover 1 and lower cover 2, device forms an independently space outside pipeline, as shown in Figure 3, upper cover 1 is with inlet 14, on inlet 14, be installed into lid 11.
The present invention adopts in device and injects liquid nitrogen and make the medium cooled and solidified in pipeline, reaches and stops the mobile object of pipeline internal medium.As shown in Figure 3, inlet 14 by upper cover 1 top injects liquid nitrogen, then close access cover 11, on the pipeline that this device is installed, form topical hypothermia, utilize the be cooled temperature of pipeline section of infrared temperature measurement gun measurement, keep temperature lower than the solidifying point of pipeline internal medium, after the medium in pipeline herein solidifies, just reached the object of blocking-up media flow.Complete after maintenance debugging, device is removed, utilize ambient temperature that the medium in pipeline is melted, recover flowing state.The maintenance debugging of the extraordinary loop of the present invention is high by occluding device reliability, is easy to dismounting, and maintenance cost is low, applied widely.
