Description
Technical field
the utility model relates to a kind of Novel cold and changes structure for pressure test device.
Background technology
existing cold exchange device pressure testing mold, the fuse of same diameter protrudes shell length difference, and need select the mold of different length specification, mold use cost is large, causes very large waste.
Summary of the invention
the purpose of this utility model is to provide a kind of Novel cold simple to operate, that versatility good, sealing is strong and changes structure for pressure test device.
above-mentioned object is realized by following technical scheme:
a kind of Novel cold changes structure for pressure test device, its composition comprises: cylindrical shell, one side end of described cylindrical shell connects closing disk, the end side mounting flange of described cylindrical shell, the side connecting end surface O-ring seal of described cylindrical shell, described end-face seal ring has arcuate slot, described arcuate slot grafting rod O-ring seal, described ring flange has seal groove, described seal groove is built with linear sealing circle, and described cylindrical shell has threaded hole, described threaded hole connection wire rod, described screw mandrel connects pipe cap, and described cylindrical shell connects hanger.
described Novel cold changes structure for pressure test device, and described closing disk has connecting thread hole, and described connecting thread hole connects full spiral shell stud, and described full spiral shell Stud connection nut, described ring flange has bolt hole, described bolt hole coupling bolt.
described Novel cold changes structure for pressure test device, is welded to connect between described cylindrical shell and described closing disk, is welded to connect between described cylindrical shell and described ring flange, and described cylindrical shell connects web joint, the hanger described in described web joint connects.
beneficial effect:
1. the utility model solves the mold of cold exchange device pressure testing in the past, and it is different that the fuse because of same diameter protrudes shell length, need select the mold problem of different length specification.
the utility model adopts linear sealing technology, solves because mold sealing surface is when passive state in pressure testing dress water process, and sealing effectiveness is not good and the problem that causes water to leak.
the utility model has good sealing, and suppress process implementation drop at dress water and do not leak, pressure testing is success once, solves and repeatedly suppresses the waste that failure causes manpower and resource, and affect the problem of maintenance duration.
the utility model has the versatility of cold exchange device with footpath different pressures grade mold, and mold is simple to operate, versatility good, sealing is strong.
accompanying drawing illustrates:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is structural representations of hanger in accompanying drawing 1.
