Description

Technical Field

[0001] The utility model relates to the technical field of sealed flange devices, in particular to a sealed flange device for the fusion sealing of a quartz tube container. Background Technique

[0002] The fusion sealing of quartz tubes is a high-precision manufacturing process that requires strict control of the flange temperature to avoid stress concentration in the quartz tubes. In early industrial practices, passive cooling methods were attempted: using materials such as asbestos cloth soaked in water and ceramic fiber felts to wrap the flange, and utilizing the latent heat of vaporization of water to absorb part of the heat. However, this method has fatal defects.

[0003] The existing patent CN 205315907 U improves the sealing performance by optimizing the structures of the sealing ring and the metal ring, but does not solve the problem of thermal deformation in high-temperature environments. The thermal expansion coefficient of the flange body (such as 304 stainless steel) is 17.2×10⁻ 6 / ℃. When the temperature rises from 25℃ to 300℃, the radial expansion amount can reach 0.46mm, far exceeding the compensation ability of the sealing ring (usually ≤0.1mm), resulting in seal failure. The core structure of this solution is the front, middle, and rear flange plates. The middle flange plate improves the sealing performance through a single-sided conical metal ring and multiple sealing rings, but there is no cooling design.

[0004] The evaporation rate of water is greatly affected by the ambient temperature and humidity. At high temperatures (>100℃), the water quickly evaporates, and the cooling effect can only be maintained for 5 - 10 minutes; after the soaked materials dry (especially organic fiber-based materials), they are prone to carbonization (carbonization rate ≥30%) under the radiation of the oxy-hydrogen flame, and even cause open flames, posing a safety risk; with the improvement of the automation level of the fusion sealing process, the passive cooling method has been gradually phased out due to its unreliability, and there is an urgent need for a technical solution that can actively and continuously control the flange temperature.

The water inlet and the water outlet are respectively communicated with two inner ends of the cooling channel, which is used to facilitate the water circulation inside the rear end cover, thereby improving the heat dissipation effect of the device.

[0009] Furthermore, the sealing mechanism includes a first sealing ring. A sealing groove is opened at the center of the other end of the surface of the front end cover. The sealing groove is arranged in a ring shape. The first sealing ring is installed inside the sealing groove. A mounting plate is fixedly connected to the surface of the front end cover near one end of the transition ring. The mounting plate is fixedly connected to the surface of the front end cover through a bolt. The mounting plate is arranged on the surface of the first sealing ring, which is used to seal the connection between the front end cover and the transition ring.

[0010] Preferably, a fixing ring is sleeved on an inner wall of the rear end cover away from one end of the front end cover. A double-cone ring is arranged inside the rear end cover. The double-cone ring is arranged between the fixing ring and the connecting ring. A sealing groove is arranged inside the connecting ring. The sealing groove is arranged on the surface of the front end cover away from one side of the transition ring. Third sealing rings are arranged at both ends of the double-cone ring. One of the third sealing rings is arranged on the surface of the fixing ring, and the other third sealing ring is arranged on the surface of the connecting ring, which is used to seal both ends of the double-cone ring installed inside the rear end cover, thereby achieving a sealing effect between the rear end cover and the front end cover.

[0012] 1. The device is fixedly installed with the transition ring, and by arranging a first sealing ring between the front end cover and the transition ring, it is convenient to achieve a sealing effect.

[0013] 2. Then insert it into the interior of the rear end cover through the connecting ring at the bottom of the front end cover, and connect the rear end cover and the front end cover through bolts. A double-cone ring is also arranged between the rear end cover and the connecting ring. The third sealing rings of the two double-cone rings are respectively fitted with the fixing ring inside the rear end cover and the surface of the connecting ring, which can improve the sealing performance of the installation between the rear end cover and the front end cover.

[0014] 3. During the use of the device, by connecting water pipes at the water inlet and outlet and making the water circulate, the purpose of cooling can be achieved. The immersion material required for passive cooling is cancelled, and a fully enclosed cooling channel is processed inside the flange body to form an active cooling system, thereby improving the use effect of the device.
