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.
