一种内涨式小口径钢管水压试验装置

Internally expanding small-caliber steel pipe water pressure test device

Abstract

本实用新型公开了一种内涨式小口径钢管水压试验装置,包括产生高压水的高压进水机构,该水压试验装置还包括能与钢管一端形成密封的封口堵头,高压进水机构的出水口端连接有能与钢管的另一端形成密封的高压进水堵头,高压进水堵头内设有连通钢管内部和出水口端的进水通道,在高压进水堵头和封口堵头上设有能够使高压进水堵头和封口堵头固定在钢管内的涨紧机构。本内涨式小口径钢管水压试验装置具有结构简单、操作方便,能够检测任何长度的小口径的钢管成品,解决了现有钢管水压试验装置存在只能检测定长钢管成品的问题。
The utility model discloses an internally expanding small-caliber steel pipe water pressure test device, which comprises a high-pressure water inlet mechanism producing high-pressure water and a sealing plug capable of forming a seal with one end of a steel pipe, wherein the water outlet end of the high-pressure water inlet mechanism is connected with a high-pressure water inlet plug capable of forming a seal with the other end of the steel pipe; and a water inlet passage connecting the inside of the steel pipe and the water outlet end is arranged in the high-pressure water inlet plug; the high-pressure water inlet plug and the sealing plug are provided with a tension mechanism capable of fixing the high-pressure water inlet plug and the sealing plug in the steel pipe. The internally expanding small-caliber steel pipe water pressure test device is simple in structure and convenient in operation, can test finished small-caliber steel pipes of various lengths and solves the problem thatthe prior steel pipe water pressure test device can only test finished steel pipes of a fixed length.
