Embodiment approach

[0025] Further, see figure 1 , figure 2 with Figure 4 , as a specific embodiment of the new plugging plug provided by the present invention, the pressing assembly 2 includes a gland 21 and a pull rod 22 arranged in the cavity 111, one end of the pull rod 22 is connected to the The gland 21 is fixedly connected, the other end of the pull rod 22 passes through the cavity 111 and protrudes from the second end of the rubber plug body 1, and a handle portion 23 is provided at its end; the gland 21 is provided with several balls 24 along its circumference, and the gland 21 is in interference fit with the cavity wall of the cavity 111 through the balls 24 . In this way, by pulling the handle part 23 so that the pull rod 22 drives the gland 21 to move down, the ball 24 squeezes the cavity wall of the cavity 111 so that the outer wall of the rubber plug body 1 and the pipe The inner walls are in tight contact, thereby achieving a pipe seal. The use of the ball 24 can effectively ...

Abstract

The invention discloses a new plugging rubber plug, which comprises a rubber plug body, the rubber plug body includes a first end and a second end, and the inside of the rubber plug body is provided with a first end connected to the rubber plug body A connected cavity, the cavity is provided with a pressing component so that the outer wall of the rubber plug body is in tight contact with the inner wall of the pipeline; the second end of the rubber plug body is also provided with a drain port, and the drain port In communication with the cavity, a drain valve is provided at the drain port. The novel plugging rubber plug described in the present invention can effectively solve the technical problems of time-consuming installation and removal of the traditional wooden plug, low efficiency and high safety risk in the prior art.

Description

technical field [0001] The invention relates to the technical field of rubber plugs, in particular to a novel plugging rubber plug. Background technique [0002] Cork is widely used in shipbuilding, hydraulic engineering construction, construction engineering and other fields. Existing wooden plugs are turned into different sizes for use in pipeline sealing and airtight testing. In the process of use, there are often the following problems: 1. The use of traditional corks for sealing usually requires manual corking. 2. The cork is blocked and the test water cannot be released in advance. After the cork at a higher position is dismantled, the construction workers are easily impacted by the test pressure water, and there is even a safety risk of falling off the scaffold. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a new type of sealing rubber plug to solve the technical problems in the prior art that ...
