Embodiment Construction

[0054] As a second embodiment, such as Figure 4 As shown, the fluid inlet and outlet unit 43 is provided on one side of the conduit end of the second unit 15 and can be connected to the pressurizing or pressure gauge to perform a gas-tight test of the pipe.

[0055] Specifically, the vertically extending fluid inlet and outlet unit 43 is formed by perforation of the blocking surface 32 of the second unit 15, thereby applying pressure or sensing pressure on the pipe cycle.

[0056] As a third embodiment, such as Figure 5 As shown, an intermediate unit 45 is provided between the first unit 11 and the second unit 15. If you want to make the frictional force of the tilting unit 23 on the conduit 26 greater than the detour of the second unit 15 based on the pressure, the inclination angle must be small. In this case, the second unit 15 is inserted into a deeper with the first unit 11, and there is difficulty in restoring the protocol. In order to solve this problem, a cylindrical hollo...

Abstract

The present invention includes: a first part (11) which has a hollow cylindrical shape and circumscribes or is inscribed in a pipe (26); and a second part (15) which has a cylindrical shape and circumscribes or is inscribed in the first part (11), wherein inclined portions (23), which have inclination angles that can hinder the second part (15) from retreating from the first part (11), are formed between the first part (11) and the second part (15) so as to correspond to each other. That is, when a pipe sealing device is mounted to the pipe and the second part (15) is retreated from the pipe (26), the inclined portions (23) of the first part (11) and the second part (15) push against each other, the first part (11) is pressed against and fixed to the pipe, and the second part (15) can no longer retreat from a limit line due to the inclination angles. Connecting or closing pipes typically involves making screws or welding, and thus requires many tools and consumes much time. In contrast, such work can be conveniently performed using the pipe sealing device of the present invention. Also, a fluid inlet and outlet portion (43) is provided, and thus a pipe sealing test can be easily performed for each section.

Description

Technical field [0001] The present invention relates to a device required for a pipe construction. More specifically, it relates to a device used in the end of the blocking conduit or when the pipe is connected, the device facilitates the airtight test and pipeline construction of the pipe. Background technique [0002] Typically, the apparatus for blocking or connecting the pipeline is mainly used as a manual means, which may have various forms. Implemented by screws or welding operations, at this time, a large amount of work tools are required and consume a large amount of costs and time. Inventive content [0003] 【technical problem】 [0004] The present invention is presented in order to solve the above problems, an object thereof is to provide a piping airtight device without an additional work tool can easily achieve the blocking or connection of the pipe, and by providing a fluid into and out unit, thereby not completed in the pipeline In the state, it is also possible to...
