Abstract
The utility model discloses a kind of high pressure flange seal clamp, comprise the seal groove of two symmetrically arranged semi-circular shape, be respectively equipped with one outside the two ends of described seal groove and be fixedly connected with otic placode, described being fixedly connected with on otic placode has mounting hole, described seal groove outer wall evenly offers several injecting hole, seal groove inwall is provided with the convex tongue snap ring of arc along its circumferencial direction, described convex tongue snap ring both sides have a filler annular groove, described convex tongue snap ring has several go out agent hole, described go out agent hole run through convex tongue snap ring, and communicate with the filler annular groove of convex tongue snap ring both sides, and be communicated with injecting hole, be fastened and fixed by clamping bolt between two seal grooves and connect otic placode connection.The utility model effectively improve high pressure flange dehisce large or flange alignment tolerance is larger time, the success rate of flange pressurized leak stoppage sealing, and after leak sealing success, there is good sealing and endurance, avoid the economic loss that continization chemical production device maintenance shut-downs causes.
Description
Technical field
The utility model belongs to high pressure flange and reveals technical field of sealing technology, is specifically related to a kind of high pressure flange seal clamp.
Background technique
In the large chemical complex of consecutive production, due to raw-material under-supply, the load of system adjusts thereupon, and the High Temperature High Pressure flange that now pipeline connects often leaks when pressure and temperature change, and the continuous seepage jeopardizing device runs.The mode of usual employing is for carry out fastening to flange bolt online, when fastening inefficacy, only have and adopt traditional fixture type on-line pressure sealant leak stopping to eliminate leak source, avoid loss of stopping, but paired flange outer rim is because the defects such as forging, installation, measurement error, machining error cause flange outer rim to match afterwards, and size deviation is large, pipeline is larger in the alignment tolerance of effect of stress lower flange, easily flange is tightly gone out to dehisce, make cannot be formed between flange and fixture effectively to fit tightly, cause shutoff failure, system shutdown keeps in repair, and causes huge economic loss.
Model utility content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, there is provided a kind of high pressure flange seal clamp, its structure is simple, ensure that Security when maintenance man operates, and sealing and plugging is respond well, avoid the situation of production system generation maintenance shut-downs.
The technological scheme that the utility model adopts is: a kind of high pressure flange seal clamp, comprise the seal groove of two symmetrically arranged semi-circular shape, be respectively equipped with one outside the two ends of described seal groove and be fixedly connected with otic placode, described being fixedly connected with on otic placode has mounting hole, described seal groove outer wall evenly offers several injecting hole, seal groove inwall is provided with the convex tongue snap ring of arc along its circumferencial direction, described convex tongue snap ring both sides have a filler annular groove, described convex tongue snap ring has several go out agent hole, described go out agent hole run through convex tongue snap ring, and communicate with the filler annular groove of convex tongue snap ring both sides, and be communicated with injecting hole, be fastened and fixed by clamping bolt between two seal grooves and connect otic placode connection.
As preferably, the quantity in described injecting hole is identical with the fixed hole quantity on flange.
As preferably, offer injecting hole place correspondence and be provided with out agent hole, and be also provided with out agent hole between two injecting holes.
As preferably, described seal groove, near the injecting hole of mounting plate position, is opened on the end face of seal groove.
The beneficial effects of the utility model are: the utility model structure is simple, effectively improve high pressure flange dehisce large or flange alignment tolerance is larger time, the success rate of flange pressurized leak stoppage sealing, and after leak sealing success, there is good sealing and endurance, avoid the maintenance shut-downs of continization chemical production device, and Security when ensure that leak sealing operator operate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the plan view of the utility model seal groove.
In figure: 1, seal groove; 2, otic placode is fixedly connected with; 3, mounting hole; 4, injecting hole; 5, convex tongue snap ring; 6, filler annular groove; 7, agent hole is gone out.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Embodiment: as depicted in figs. 1 and 2, the utility model comprises the seal groove 1 of two symmetrically arranged semi-circular shape, be respectively equipped with one outside the two ends of described seal groove 1 and be fixedly connected with otic placode 2, described being fixedly connected with on otic placode 2 has mounting hole 3, described seal groove 1 outer wall evenly offers the injecting hole 4 identical with flange fixed hole quantity, seal groove 1 inwall is provided with the convex tongue snap ring 5 of arc along its circumferencial direction, described convex tongue snap ring 5 both sides have a filler annular groove 6, described convex tongue snap ring 5 has several go out agent hole 7, described go out agent hole 7 run through convex tongue snap ring 5, and communicate with the filler annular groove 6 of convex tongue snap ring 5 both sides, and be communicated with injecting hole 4, be fastened and fixed connection otic placode 2 by clamping bolt between two seal grooves 1 to connect, the position correspondence wherein seal groove 1 offering injecting hole 4 has out agent hole 7 on convex tongue snap ring 5, and convex tongue snap ring 5 between two injecting holes 4 also has out agent hole 7, described seal groove 1, near the injecting hole 4 of mounting plate position, is opened on the end face of seal groove 1.
Seal groove 1 is fixed on the gap of flange by convex tongue snap ring 5 by the utility model, and by being fixedly connected with otic placode 2, two seal grooves 1 are connected and fix, then by injecting sealing compound to injecting hole 4, sealing compound enters into flange slot and stuffing box packing back, along with filling up of space between flange, the rising of pressure, part sealant can outwards be extruded, by setting out agent hole 7 and filler annular groove 6, make the sealing compound be extruded pass through agent hole 7 and enter filler annular groove 6, flexible filler secondary in filler annular groove 6 is promoted, raise and eliminate gap, it is made to be close on end face of flange, eliminate the sealing compound deficiency because injecting hole 4 enters, filler all effectively can not be piled up the deficiency forming seal chamber, thus reach the effective sealing of flange leakage.
The utility model structure is simple, effectively improve high pressure flange dehisce large or flange alignment tolerance is larger time, the success rate of flange pressurized leak stoppage sealing, and after leak sealing success, there is good sealing and endurance, avoid the maintenance shut-downs of continization chemical production device, and Security when ensure that leak sealing operator operate.
