Description
Technical field
The utility model relates to a kind of tightness test fixture, particularly relates to a kind of interior external pressure integrated combined type tightness test fixture.
Background technology
When carrying out the corrugated tube valve tightness test of ripple tubing product to be checked especially one end open, tightness test or strength test need be carried out respectively to pressure and external pressure in product to be checked.
At present for pressing in this type of bellows part, external pressure tightness test adopts usually is two cover frocks, a set of for external pressure test, a set of for internal pressure test, twice cargo handling process need be carried out to product to be checked, handling trouble, the operation person of being awkward labour intensity is large, inefficiency, experimentation cost is high, and not easily takes care of.
Summary of the invention
The purpose of this utility model is just to provide a kind of interior external pressure integrated combined type tightness test fixture, to solve the problem.To achieve these goals, the technical solution adopted in the utility model is such: external pressure integrated combined type tightness test fixture in a kind of, comprise cylindrical shell, one side opening of described cylindrical shell, the side of the opening of described cylindrical shell is provided with the gland corresponding with opening, between described cylindrical shell and gland, is provided with seal pad assembly; Limiting plate, spacing anchor ear, limit pull rod, half round clamp, half ring washer and seal pad is provided with in described cylindrical shell, described limiting plate, spacing anchor ear and limit pull rod are positioned at the side away from cartridge openings of described cylindrical shell, and described half round clamp, half ring washer and seal pad are positioned at the side of the close cartridge openings of described cylindrical shell successively.
As preferred technical scheme: be also provided with ripple fender in described cylindrical shell.Product to be checked to be measured can be made more firm.
As preferred technical scheme: be also provided with the packing washer corresponding with described seal pad.Can make sealing effectiveness more, result is more accurate.
As preferred technical scheme: be also provided with O shape rubber seal between described cylindrical shell and seal pad assembly.Can make sealing effectiveness more, result is more accurate.
Compared with prior art, the utility model has the advantage of: by a set of frock, the original function realized by two cover frocks is concentrated on one, inside and outside pressure exchange tightness test is realized by simply combining, by the processes shrink originally loading and unloading twice be once, greatly reduce the lay time, improve work efficiency, significantly reduce the labour intensity of operator, and easily take care of.
