Problems solved by technology

Although this can prevent the closed water test water from leaking at the sewer port, the closure inserted into the sewer pipe is likely to be sucked into the depth of the pipe by the negative pressure suction of the sewer pipe, causing blockage
Although the blockage made of hard materials cannot be sucked into the sewer pipe, its surface is not elastic, so it cannot completely seal the sewer port, and even damage the PVC sewer pipe during installation

Embodiment 1

[0023] Example 1, such as Figure 1-2 As shown, the plug body of the closed water test plug for interior decoration is an integrated plug structure composed of a vent pipe 1 and a sealing surface 2, and is made of an elastic material through injection molding or machining. The elastic material can be Choose from silicone or rubber.

[0024] Such as figure 2 As shown, the ventilation pipe 1 is a hollow cylindrical pipe body with openings at both ends for air circulation, so the structural shape of the ventilation pipe is not limited to the cylindrical pipe body. In order to allow the ventilation pipe 1 to be smoothly inserted into the water outlet, the maximum diameter of the outer edge of the ventilation pipe 1 should be smaller than the diameter of the water outlet.

[0025] Such as Figure 1-2 As shown, the bottom of the ventilation pipe 1 is also provided with a sealing surface 2 for fitting and blocking the water outlet. The sealing surface 2 is in the shape of a trunc...

Embodiment 2

[0030] Example 2, such as image 3 As shown, the sealing surface 2 of the closed water test plug for indoor decoration is a bowl formed by an upper opening parabola rotating around the parabolic axis of symmetry. An opening is provided at the bottom, and the opening is set on the bottom of the ventilation pipe 1 and integrally fixedly connected with the bottom of the ventilation pipe 1 .

[0031] The outer edge of the section with the largest diameter at the top of the bowl-shaped sealing surface 2 closely matches the inner diameter of the downpipe.

[0032] During use, the closed water test plug described in Example 2 is inserted into the downpipe, and water is injected into the closed water test area. 3 As an expansion device, it expands outward under the action of liquid pressure, so that the tight fit between the sewer pipe 1 and the outer wall of the sealing surface 2 becomes an interference fit, and the seal is realized.

Embodiment 3

[0033] Example 3, such as Figure 4-5 As shown, the closed water test plug for indoor decoration also includes a detachable expansion device 4, which is sleeved on the vent pipe 1 and is used to expand the expansion device 4 of the sealing surface 2 in the direction of the inner edge of the lower nozzle. The expansion device 4 can be made of the same solid elastic material or hard material as the closed water test plug described in this application.

[0034] The expansion device, such as Figure 5 As shown, it includes a through-heart tube and an expansion plug. The through-heart tube is a body whose inner diameter is larger than that of the vent tube. The outer surface of the bottom of one end of the through-heart tube is provided with an expansion plug 6 for expanding the sealing surface 2. The expansion plug 6 as Figure 5 The shape shown is the same as the cross-sectional shape of the truncated cone formed by the sealing surface 2, which is also a truncated cone.

Abstract

A closed water test plug for interior decoration is used for waterproof tests. The closed water test plug for interior decoration at least comprises a plug body made of an elastic material. The plug body comprises a ventilation pipe and a seal face. The closed water test plug for interior decoration has the beneficial effects that since the ventilation structure is arranged in the closed water test plug, the inner portion of a pipe communicates with indoor air, and the situation that when other users use a sewage pipe, instantly-generated negative pressure sucks the closed water test plug intothe pipe, and then the pipe is blocked is avoided.

Description

technical field [0001] The application relates to the field of inspection tools for interior decoration, in particular to a closed water test plug for interior decoration used for waterproof testing. Background technique [0002] In the interior decoration work, according to the relevant construction standards, the water-repellent treatment of the ground is required in functional areas such as toilets and shower rooms. The test to check the waterproof effect is called the closed water test. The closed water test is to close the sewer pipe, store water in the waterproofed area and keep it for a period of time, and then judge whether there is any water leakage defect in the waterproof project by measuring the water level. During the closed water test, because the sewer pipe always needs to be closed to avoid leakage, inflatable balloons, corks, or other objects smaller than the inner diameter of the sewer pipe are usually used to seal the sewer port during construction. Thoug...
