The explosion-proof cabinet strength water pressure detection tool can well block and seal holes in the explosion-proof cabinet without complex operation, and the rubber pads are not easy to extrude through the rubber flanges, so that the explosion-proof cabinet can be quickly and reliably sealed.
Description
Technical Field
The utility model relates to a flame proof cabinet field, concretely relates to flame proof cabinet intensity water pressure detection frock.
Background
After the explosion-proof cabinet is manufactured, water pressure detection is needed so as to determine whether the explosion-proof cabinet can withstand the specified pressure without deformation. Before water pressure detection, a hole in the explosion-proof cabinet needs to be blocked by a blocking tool, only one water through hole is reserved, and an opening in the explosion-proof cabinet needs to be sealed by a cover plate sealing cover after a sealing ring is arranged on the end face where the opening is located. The structure of the plugging tool generally comprises: a shrouding, one to locking plate, a sealing washer, wear to be equipped with a screw on the shrouding, the hole that supplies the screw to pass on the shrouding needs the welding to seal. The blocking tool is complex, so that the blocking work of the hole on the explosion-proof cabinet is complex and can be finished in a long time, thereby greatly reducing the production efficiency; in addition, the sealing ring on the opening of the explosion-proof cabinet is easily pressed out by high water pressure to cause water leakage.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the explosion-proof cabinet strength water pressure detection tool capable of rapidly and reliably sealing the explosion-proof cabinet is provided.
In order to solve the above problem, the utility model discloses the technical scheme who adopts does: explosion-proof cabinet intensity water pressure detects frock, its characterized in that: the method comprises the following steps: at least one annular rubber pad and at least one rubber stopple are provided with the annular rubber flange of round in rubber pad inner circle lower limb department, and the shape of rubber stopple is the round platform shape, and the height of rubber pad is 5 ~ 10mm, and the height of rubber flange is 5 ~ 10mm, and the thickness of rubber flange is not less than 5mm, and the contained angle of rubber stopple generating line and axis is 8 ~ 16.
Further, explosion proof cabinet intensity water pressure detection frock, wherein: the rubber pad and the rubber flange are integrally formed, and the hardness of the rubber pad and the rubber flange is 50-60 HA.
Further, explosion proof cabinet intensity water pressure detection frock, wherein: the hardness of the rubber hole plug is 40-50 HA.
Further, explosion proof cabinet intensity water pressure detection frock, wherein: the height of the rubber pad is equal to that of the rubber flange.
The utility model has the advantages that: the explosion-proof cabinet strength water pressure detection tool can well block and seal holes in the explosion-proof cabinet without complex operation, so that the production efficiency can be greatly improved, and the rubber gasket is not easy to be extruded through the rubber flanges, so that the explosion-proof cabinet can be quickly and reliably sealed.
Drawings
FIG. 1 is the explosion proof cabinet intensity water pressure detect frock in the schematic structure of rubber pad.
FIG. 2 is the explosion proof cabinet intensity water pressure detect frock in the structural schematic diagram of rubber stopple.
Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
As shown in FIG. 1 and FIG. 2, the explosion suppression cabinet strength water pressure detection tool comprises: at least one annular rubber pad 1 and at least one rubber stopple 3, border department is provided with annular rubber flange 2 of round under 1 inner circle of rubber pad, the shape of rubber stopple 3 is the round platform shape, the high a of rubber pad 1 is 5mm, the height c of rubber flange is 5mm, the thickness b of rubber flange is 5mm, the contained angle alpha of 3 generating lines of rubber stopple and axis is 12, contained angle alpha should not too big or too little, it is too big, difficult sealed hole, it is too little, make rubber stopple 3 pressed into in the hole easily. The width between the inner ring and the outer ring of the rubber pad 1 can not be too small, and at least needs to exceed half of the width of the end face where the opening is formed, so that most of the cover plate can be supported, and the cover plate is not easy to deform during cover sealing.
In the present embodiment, the rubber pad 1 and the rubber rib 2 are integrally formed, and both have a hardness of 55HA, and the rubber pad 1 and the rubber rib 2 are not too soft and too hard, so that the rubber pad 1 is easily pressed out due to the too soft hardness, and a seal is not easily formed due to the too hard hardness. The hardness of the rubber hole plug 3 is 45HA, the hardness of the rubber hole plug 3 cannot be too soft or too hard, the rubber hole plug 3 is too soft, the rubber hole plug 3 is easily pressed into a hole to cause sealing failure, and the rubber hole plug 3 is too hard to form sealing.
During sealing, the rubber hole plug 3 is plugged into a hole on the explosion-proof cabinet to seal the hole, and the rubber hole plug 3 is more and more tight along with the rise of water pressure; the rubber pad 1 is laid on the end face where the explosion-proof cabinet is open, and the rubber flange 2 needs to be inserted into the opening during laying, so that the rubber pad 1 can be clamped in the opening through the rubber flange 2 and is not easy to be extruded.
