Embodiment Construction

[0015] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0016] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or an intervening element may also exist. When a component is said to be "connected" to another component, it may be directly connected to the other com...

Abstract

The invention discloses a corrugated pipe pressure test tool. The corrugated pipe pressure test tool comprises a bottom plate, wherein two sealing plates are can be adjustably and fixedly mounted at two ends of the bottom plate along the length direction of the bottom plate; a groove is correspondingly formed in the inner side of each of the two sealing plates; two ends of a corrugated pipe are hermetically assembled in the corresponding grooves; a through hole is formed in each groove; the through hole in one of the sealing plates is fixedly connected with a pressure gage interface extendingtowards the outer side in a sealing mode, and the through hole in the other of the sealing plates is fixedly connected with an air pipe connector extending towards the outer side in the sealing manner; and a blocking part which is positioned at the periphery of the corrugated pipe and is used for preventing the corrugated pipe from distorting and deforming is arranged between the two sealing plates. The corrugated pipe pressure test tool is simple in structure and simple and convenient to operate; moreover, the corrugated pipe is not distorted due to internal pressure in the test process, so that the corrugated pipe needing a pressure test can be effectively subjected to the pressure test, and the quality and requirements of the corrugated pipe can meet the requirements on vacuum equipment.

Description

technical field [0001] The invention relates to a pressure test tool, in particular to a bellows pressure test tool. Background technique [0002] In the manufacture of vacuum vessels, many joints are connected by bellows. Before welding to the vacuum vessel, the internal pressure test should be done according to the technical requirements. Usually, the bellows will be distorted due to lack of rigidity when there is pressure. Deformation, after the bellows are twisted and deformed, the internal pressure test cannot be carried out according to the requirements, so it cannot be guaranteed whether the bellows can meet the performance and requirements of use. Contents of the invention [0003] The object of the present invention is to provide a corrugated pipe pressure test tool to solve the problem of distortion and deformation of the corrugated pipe in the prior art during the internal pressure test. [0004] For reaching this purpose, the present invention adopts following...
