Abstract

The present invention relates to a kind of frock, more particularly to a kind of uniform internal diameter cylinder airtightness testing tool.Described frock includes plug and connecting rod, and plug is sealingly mounted at the two ends of cylinder to be detected, is linked together by connecting rod between plug, and connecting rod is located in cylinder.The technical scheme simple structure, being connected for two plugs is being realized by the inside of testpieces, it is to avoid using complicated fixing device outside testpieces, tool structure is simplified compared with prior art, easy to operate, shortens test period.Meanwhile, gas pressure intensity is taken with the Lalique of connecting rod, fixed reliability is higher compared with prior art.

Description

A kind of uniform internal diameter cylinder airtightness testing tool
Technical field
The present invention relates to a kind of frock, more particularly to a kind of uniform internal diameter cylinder airtightness testing tool.
Background technology
Isometrical endoporus cylinder material is detected with the presence or absence of sand holes, the general method for using is detected for air-tight test. In the prior art, the air-tightness detection tool for using includes two plugs, and plug is sealed in cylinder to be detected respectively The two ends of body, then to injection pressure in cylinder.Two plugs are fixed outside cylinder, it is to avoid in air pressure masterpiece It is ejected with lower end cap.This kind of frock uses external stability, complex structure, and fixed poor reliability, shadow Ring the efficiency of experiment.
The content of the invention
The purpose of the present invention is:A kind of simple structure, fixed highly reliable uniform internal diameter cylinder air-tightness are provided Test tool.
The technical scheme is that:A kind of uniform internal diameter cylinder airtightness testing tool, it is characterized by:It is described Frock include plug and connecting rod, plug is sealingly mounted at the two ends of cylinder to be detected, passes through between plug Connecting rod is linked together, and connecting rod is located in cylinder.
As the technical program one kind improve, connecting rod be the screwed screw rod in one end, screw rod with wherein One plug is integrated, and another plug inner side is provided with screw.The technical scheme simplifies part Number, is easy to the installation under operating condition of test.
Improved as one kind of the technical program, one of plug is air intake valve.The technical scheme is simultaneously The technical problem of air-tight test pressurization is solved, a frock multiple use is realized.
Beneficial effects of the present invention:The technical scheme simple structure, two are being realized by the inside of testpieces Plug is connected, it is to avoid using complicated fixing device outside testpieces, compared with prior art Tool structure is simplified, it is easy to operate, shorten test period.Meanwhile, the Lalique with connecting rod is convinced Body pressure, fixed reliability is higher compared with prior art.
Brief description of the drawings
Fig. 1 is:Structural representation of the invention.
In figure:1 is band screw rod joint, and 2 is sealing ring, and 3 is plug, and 4 is cylinder.
Specific embodiment
The technical program is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, the frock in the present embodiment includes band screw rod joint 1, sealing ring 2 and plug 3, band One end of joint 1 of screw rod is air intake valve, and air intake valve is integrated with screw rod, band screw rod joint 1 One end be provided with screw thread, be machined with screw on the inner side end under test conditions of plug 3, the screw can Coordinate with screw rod.
During experiment, plug is sealingly mounted at one end of the endoporus of cylinder 4, then will be sealed with screw rod joint 1 Installed in the other end of cylinder 4, will be connected with screw rod joint 1 and plug 2 with the cooperation of screw by screw rod It is fixed.By the air intake valve with screw rod joint 1 to injection pressure in cylinder 4, tested.
