Description

Technical Field

[0001] This utility model belongs to the field of civil defense engineering technology, and in particular relates to a pressure measuring pipe through a sealed partition wall structure. Background Technology

[0002] A pressure measuring pipe for a sealed partition wall is a device installed on a sealed partition wall to measure the pressure difference between the two sides of the wall. It is widely used in places with high requirements for airtightness, such as civil defense projects and clean rooms. By accurately measuring the pressure difference, the air pressure status on both sides of the partition wall can be grasped in a timely manner, which helps to judge whether the airtightness of the partition wall is good. Its structure usually includes a sleeve embedded in the wall and a pressure measuring pipe running through it, and is equipped with sealing components to ensure that the partition wall is kept airtight when measuring pressure, preventing the leakage of air, harmful gases, etc., and ensuring the safety and stability of the internal environment of the project.

[0003] In construction projects, especially in areas with high protection requirements such as civil defense projects, the sealing requirements for the location where the pressure measuring pipe passes through the airtight partition wall are very high. However, the simple sealing materials used to seal the pressure measuring pipe through the airtight partition wall are insufficient to ensure the tightness of the seal between the pressure measuring pipe and the pre-embedded sleeve, as well as between the pressure measuring pipe and the wall. Over time and with environmental changes, gaps are prone to appear, leading to leakage of air or other media, affecting the accuracy of pressure measurement and the protective performance of the airtight partition wall. Therefore, it is necessary to provide a pressure measuring pipe through the airtight partition wall structure. First, the pressure measuring pipe is centered and then effectively sealed by grouting and sealing components, improving the stability and sealing performance of the pressure measuring pipe in the airtight partition wall.

Detailed Implementation

[0013] In the following description, embodiments of the pressure measuring tube penetrating a sealed partition wall according to the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates a pressure-measuring pipe penetrating a sealed partition wall according to an embodiment of the present invention. The pipe includes a pre-embedded sleeve 1 embedded within the wall. A water-stop plate 2 is fixedly connected to the surface of the pre-embedded sleeve 1, and the water-stop plate 2 is embedded within the wall. A pressure-measuring pipe 3 is installed through the inner cavity of the pre-embedded sleeve 1. Sealing components 4 are provided on both sides of the surface of the pressure-measuring pipe 3. The sealing components 4 include a positioning plate 41 that engages with the inner cavity of the pre-embedded sleeve 1. Multiple annularly distributed grouting holes 6 are opened on the surface of the positioning plate 41. A compression ring 43 is injection molded on the side near the positioning plate 41. The device is integrally molded with multiple annularly distributed plugs 7, which engage with the inner cavity of the grouting hole 6. Through the cooperation of the plugs 7 and the grouting hole 6, the user can easily fill the surface of the pressure testing pipe 3 with a sealing mortar layer 45 after centering it, ensuring a tight seal between the embedded sleeve 1 and the pressure testing pipe 3. Simultaneously, the plugs 7 can seal the grouting hole 6 after filling, preventing leakage of the uncured sealing mortar layer 45. The positioning plate 41, with multiple integrally molded plugs on the side near the embedded sleeve 1, has multiple... Positioning blocks 8 are arranged in a ring and engage with the inner cavity of the pre-embedded sleeve 1. The positioning blocks 8 provide a locking connection between the positioning disc 41 and the pre-embedded sleeve 1, and simultaneously position the pressure testing pipe 3, ensuring that the center axis points of the pressure testing pipe 3 and the pre-embedded sleeve 1 coincide, thus ensuring the uniformity of the sealing mortar layer 45 during filling. A rubber bushing 42, fitted onto the surface of the pressure testing pipe 3, is fixedly connected to one side of the positioning disc 41. A compression ring 43 is engaged with the surface of the rubber bushing 42. One side of the compression ring 43... Multiple ring-shaped elastic plates 44 are integrally injection molded. The end of the elastic plate 44 away from the extrusion ring 43 is pressed against the surface of the rubber bushing 42. A leak-sealing mortar layer 45 is filled between the inner cavity of the pre-embedded sleeve 1 and the surface of the pressure measuring pipe 3. Both sides of the surface of the pressure measuring pipe 3 are fitted with sealing caps 5. Screws 9 are inserted through the four corners of one side of the sealing cap 5. One end of the screw 9 passes through the sealing cap 5 and is fixedly connected to the wall. The inner wall of the sealing cap 5 is set as an inner arc surface. The inner wall of the sealing cap 5 is tightly pressed against the surface of the elastic plate 44.

[0015] Working principle: When using this utility model, the user inserts the pressure testing pipe 3 into the inner cavity of the pre-embedded sleeve 1. Then, the user places the positioning disc 41 on the surface of the pressure testing pipe 3 and pushes the positioning disc 41 so that it engages in the inner cavity of the pre-embedded sleeve 1, thus centering the pressure testing pipe 3 within the inner cavity of the pre-embedded sleeve 1. The user then injects a layer of sealing mortar 45 into the inner cavity of the pre-embedded sleeve 1 through the grouting hole 6 to fill and seal the gap between the pre-embedded sleeve 1 and the pressure testing pipe 3. Finally, the user places the extrusion ring 43 on the surface of the pressure testing pipe 3 and presses the extrusion ring 43 to compress the pressure testing pipe 3. 3. The surface plug 7 is inserted into the inner cavity of the grouting hole 6 to seal the grouting hole 6. At the same time, the extrusion ring 43 extrudes the rubber bushing 42, so that the rubber bushing 42 is tightly attached to the joint between the pre-embedded sleeve 1 and the pressure measuring pipe 3. Meanwhile, the elastic clamping plate 44 is elastically clamped on the surface of the rubber bushing 42, so that the inner wall of the rubber bushing 42 is tightly attached to the surface of the pressure measuring pipe 3. Finally, the user puts the sealing cover 5 on the surface of the pressure measuring pipe 3, so that the inner wall of the sealing cover 5 extrudes the elastic clamping plate 44, enhancing the clamping effect on the rubber bushing 42. The sealing cover 5 is then fixed to the wall with screws 9.

[0016] In summary: The pressure testing pipe penetrates the sealed partition wall structure. Through the cooperation of the pre-embedded sleeve 1 and the water-stop plate 2, a passage through the wall is provided for the pressure testing pipe 3. Then, through the cooperation of the sealing component 4 and the sealing cover 5, the space between the pre-embedded sleeve 1 and the pressure testing pipe 3 and both sides are sealed, thus achieving the purpose of simple and quick installation and continuous compression sealing.
