Description

Technical Field

[0001] This utility model relates to the field of floor drain technology, specifically to a stainless steel CF8 material floor drain. Background Art

[0002] Floor drains are important interfaces connecting the floor and drainage system in buildings. To ensure the integrity of fire compartments in nuclear power plants and to prevent fresh air from entering and circulating during a fire, thus preventing the spread of fire, floor drains in nuclear power plants must be sealed.

[0003] For example, Chinese patent CN203729391U discloses a device for a floor drain. The device includes a floor drain body, a positioning ring inside the floor drain body, an adjustment ring inside the positioning ring, a body inside the adjustment ring, a cover inside the body, and a neoprene sleeve tightly fitted to the lower part of the floor drain body. This drain installation structure is made of A48 grade cast iron, which has excellent corrosion resistance. The neoprene rubber sleeve ensures a good seal at the bottom of the drain body. The positioning ring, along with its internal adjusting ring and the drain body, provides a seal above the drain body. The positioning ring is secured with hexagonal screws, significantly reducing the probability of nuclear leakage and opening a new chapter in nuclear safety. This also improves the level of nuclear power equipment manufacturing and related material research in my country. However, in practical application, because the drain body lacks any connecting and fixing devices, it is likely to separate under strong impact, resulting in poor stability during long-term use. To solve this problem, we propose a stainless steel CF8 drain. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stainless steel CF8 floor drain, which solves the problems mentioned in the background art.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A stainless steel CF8 floor drain includes: a floor drain body, a sedimentation tank inside the floor drain body, and several internal hex bolts on the outside of the floor drain body.

[0007] By adopting the above technical solution, by setting up a sedimentation tank, and by using the drain body, sedimentation tank and internal hex bolts together, it is easy to fix the drain body in the required position later. Under strong impact, the two will separate, resulting in poor fixation of the drain body during long-term use.

[0008] Preferably, the hexagonal socket bolt is connected to the drain body.

[0009] By adopting the above technical solution and setting the drain body, since the internal hexagonal bolts are threaded together with the threaded groove, it is easy to fix the drain body in the required position later.

[0010] Preferably, the inner circular wall of the sedimentation tank is provided with a plurality of filter holes.

[0011] By adopting the above technical solution and setting up a sedimentation tank, the water can be filtered through the through holes inside the sedimentation tank.

[0012] Preferably, a washer is provided below the internal hex bolt.

[0013] By adopting the above technical solution and setting up hexagon socket head cap screws, the presence of washers underneath the screws increases the overall stability after installation, thereby greatly reducing the probability of nuclear leakage. This opens a new chapter in nuclear safety and improves the level of nuclear power equipment manufacturing and related material research in my country.

[0014] Preferably, both the drain body and the sedimentation tank are made of cast iron.

[0015] By adopting the above technical solution and setting the drain body, since both the drain body and the sedimentation tank are made of Grade A cast iron (stainless steel CF8 material), they have good corrosion resistance.

[0016] Preferably, the internal hex bolt is made of alloy steel.

[0017] By adopting the above technical solution and setting the internal hexagon bolts, which are made of alloy steel, the internal hexagon bolts have better stability and toughness, and good corrosion resistance.

[0018] Preferably, an outwardly inclined support is provided below the sedimentation tank, and the support is integrally formed with the sedimentation tank.

[0019] In summary, the present invention has the following main advantages:

[0020] By incorporating hexagonal socket head cap screws, which are made of alloy steel, the screws exhibit improved stability and toughness, along with excellent corrosion resistance. Furthermore, the presence of washers beneath the hexagonal socket head cap screws enhances overall stability after installation, significantly reducing the likelihood of nuclear leakage. This has opened a new chapter in nuclear safety and elevated the level of nuclear power equipment manufacturing and related material research in my country. Additionally, the floor drain body, made of Grade A cast iron (or CF8 stainless steel), provides excellent corrosion resistance, as both the drain body and sedimentation tank are constructed from this material.
