A quartz rod fixing and sealing device

Abstract

The invention discloses a quartz handle rod fixing and sealing device which is composed of a first O-type sealing loop, bolts, a first sealing ring, a fixing pin, a first fixing ring, a second O-type sealing loop and a second sealing ring. Sealing of a quartz handle rod is achieved through mechanical sealing of the upper O-type sealing loop, the lower O-type sealing loop, the upper sealing ring and the lower sealing ring, the bolts are used for fastening, and no air leakage phenomenon is generated in the use process; and the sealing loops and the sealing rings can be used repeatedly. Meanwhile, in the use process, no phenomenon of filler falling is generated, and product quality is not influenced. Thus, according to the quartz handle rod fixing and sealing device, the structure and the sealing manner are both changed, and the beneficial effects of being reliable in sealing, low in cost, free of hazardous substances and the like are achieved.

Description

technical field [0001] The invention relates to a fixing and sealing device, in particular to a quartz rod fixing and sealing device. Background technique [0002] The existing fixing and sealing device is composed of fixing pins, sealing rings, sealing rings, fixing rings and other components. After connecting the fixing rings with the frame through fixing pins and bolts, the quartz rod can be fixed. Gas is introduced, so the connection is required to be airtight, and it is mainly used in devices such as quartz glass tube drawing and optical fiber drawing. [0003] as attached figure 1 As shown, the existing fixing and sealing device is to pass the fixing pin through the quartz rod, connect the fixing ring and the frame through bolts, and seal the gap between the frame and the fixing ring through a sealing ring and a type rubber ring. The gap between the pin and the retaining ring is sealed by inserting quartz wool. In the above-mentioned device, the quartz wool is stuff...

AI Technical Summary

Problems solved by technology

In the above device, the quartz wool is stuffed into the gap between the fixed pin and the fixed ring through tools, and the degree of tightness of different operators is inconsistent, and there is an air leakage phenomenon.

Secondly, the inside of the rod is filled with gas. During use, under the action of air pressure, the quartz wool will fall off, resulting in unstable air pressure in the rod and affecting product quality.

Again, the shedding quartz wool falls directly on the product under the action of gravity, affecting product quality, and at the same time inhaling the quartz wool fiber is harmful to the human body

Finally, quartz wool is a one-time consumable, and at the same time the price is higher, resulting in an increase in product cost
