Background technique
At present, cylindrical shell or body tube drawing technology are widely used in the interface of various high pressure pipe lines and high pressure cylindrical shell equipment, because arm that the employing extruding is extracted or ozzle and body or cylindrical shell are that seamless link is integral, thereby avoided the arm of welding fabrication or the welding residual stress of ozzle, thereby pipeline or device ' have been improved greatly; But its maximum problem is that arm or the ozzle extracted generally can be too not high, if thereby adopt the method for welded seal during the hydrostatic test, welding heat affected zone certainly will to be removed after the hydrostatic test, in the design of arm, just must consider the loss of this part length of tube like this, thereby can adopt the way that increases person in charge's thickness, will increase equipment cost greatly like this, the residual stress that welding simultaneously forms is not eliminated fully, the safe operation of equipment has from now on been brought hidden danger yet.
Summary of the invention
The purpose of this utility model is to exist when adopting welded seal when now the ozzle of extrusion modling or arm being carried out the hydrostatic test influence ozzle or prop up length of tube and have the problem of remaining welding stress, designs a kind of seal arrangement that can carry out pressure test to ozzle or arm that need not to weld.
The technical solution of the utility model is:
A kind of heat extrusion compacting arm hydrostatic test orifice sealing device, it mainly covers 4 by blind plate its feature, dunnage 3, the flanged (FLGD) pipe nipple 5 in two ends, blind flange 6, nut 11 and screw rod 2 are formed, blind plate lid 4 lids are contained on the arm 8, dunnage 3 is arranged in main pipe or cylindrical shell 1 and relative with described arm 8, arm 8 links to each other by nut 11 and screw rod 2 with dunnage 3, between the end face of blind plate lid 4 and arm 8, seal ring 7 is installed, on blind plate lid 4, offer vent hole 10, one end of the flanged (FLGD) pipe nipple 5 in two ends links to each other with blind plate lid 4, the other end links to each other with blind flange 6, and vent hole 10 is communicated with the inner chamber of the flanged (FLGD) pipe nipple 5 of arm 8 inner chambers and two ends respectively.
The upper end spinning of described screw rod 2 is on blind plate lid 4.
The two ends of the flanged (FLGD) pipe nipple 5 in described two ends all are equipped with seal ring.
The beneficial effects of the utility model:
(1) the utility model is owing to be to adopt non-welding method to seal the mouth of pipe of hot drawing arm, thereby can not stay residual stress by line up, improved the general safety performance of extracting tube apparatus or pipeline.
(2) the utility model can lower equipment or pipeline to extracting the requirement of mouthful thickness or height, thereby improves the yield rate of extracting mouthful technology, lowers cost of production.
(3) the utility model method is simple, and the efficient height can not cause damage to bulk material.
Description of drawings
Fig. 1 is the structural representation of seal arrangement of the present utility model.
Fig. 2 is the structural representation of blind plate lid of the present utility model.
