Abstract
The utility model discloses a pull rod type spray tube toper screw thread pressure test frock, including a pull rod, one section straight thread has been processed respectively to the both ends excircle of pull rod, and the cover is equipped with a gland respectively on the straight thread at this both ends. The utility model discloses a device is after the welding process of above-mentioned spray tube, is the toper screw thread to the spray tube both ends, carries out the leakproofness test to spray tube both ends welding seam to the experimental frock that needs when solving this kind of form compression test.
Description
Technical Field
The utility model belongs to the technical field of mechanical equipment makes, a pull rod type spray tube toper thread pressure test frock is related to.
Background
In mechanical equipment manufacturing process, the work roll cooling part disposes a large amount of cooling spray pipes, like figure 1, the spray pipe of various models need be done pressure test after the both ends subassembly is accomplished the welding, and test pressure is 16bar generally, and spray pipe both ends screw thread is R4 cun, and this both ends screw thread is the taper thread, adopts ordinary plug effectively sealed, needs to develop a frock that is used for spray pipe taper thread pressure test urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a pull rod type spray tube toper screw thread pressure test frock has solved under the prior art condition, in the work roll cooling process, the unable effective sealed problem of spray tube toper screw thread pressure test plug.
The utility model discloses the technical scheme who adopts is, a pull rod type spray tube toper screw thread pressure test frock, including a pull rod, one section straight thread has been processed respectively to the both ends excircle of pull rod, and the cover is equipped with a gland respectively on the straight thread at these both ends.
The utility model discloses a pull rod type spray tube toper thread pressure test frock, its characterized in that still lies in:
and a sealing ring is arranged in the groove of the inner end surface of the pressurizing cover.
The outer end face of the pressurizing cover is welded with a blind cover.
The beneficial effects of the utility model are that, after the welding process of above-mentioned spray tube, be the toper screw thread to the spray tube both ends, carry out the leakproofness test to spray tube both ends welding seam to the experimental frock that needs when solving this kind of form compression test.
