て取り付けられている。[0005] Reference numeral 6 denotes an outer tube made of glass such as quartz, which has good ultraviolet transmittance, and this outer tube 6 is provided with a general packing 7 such as an O-ring in an attachment hole 5 provided at the center of the jacket cover 4. It is fitted and attached while sealing with no leakage.

6をジャケット蓋4にパッキン7或いは接着剤9を利用

造コストが非常に高くなってしまったり、シールの耐久
性が劣ってしまったりする。However, the outer tube 6 for protecting the ultraviolet lamp 8 is fitted to the mounting hole 5 using the packing 7 or the adhesive 9 on the jacket lid 4 as in the conventional ultraviolet sterilizer. If attached, the manufacturing cost would be very high and the durability of the seal would be poor.
【0009】まず図5に示すように、Oリングのような
パッキン7を利用してシールしながら外管6をジャケッ
ト蓋4に取付穴5に嵌め合わせて取り付ける場合には、
外管6の製造に非常に高い寸法精度が要求され、歩留ま
りが非常に低くなるのでコストが高くなってしまう。First, as shown in FIG. 5, when the outer tube 6 is fitted in the mounting hole 5 in the jacket lid 4 while sealing using a packing 7 such as an O-ring,
Very high dimensional accuracy is required for the manufacture of the outer tube 6, and the yield is very low, so that the cost is high.
【0010】Oリングを利用してシールする場合に、直
径20mm程度の外管6には、外径寸法でプラス0m
m、マイナス0.06mm程度の精度が要求される。[0010] In the case of sealing using an O-ring, the outer tube 6 having a diameter of about 20 mm has an outer diameter of 0 m.
m, minus 0.06 mm accuracy is required.
【0011】しかしながら一般に製造される直径20m
m程度の石英管の場合の外径寸法は、プラス、マイナス
0.5mm程度の精度である。[0011] However, generally manufactured diameter 20m
The outer diameter in the case of a quartz tube of about m has an accuracy of plus or minus about 0.5 mm.

度を満たした石英管を製造するか、一般に製造された石
英管を熱旋盤を利用して後加工するか、或いは寸法精度
を満たすものだけを選別するかの何れかによらなければ
ならない。Therefore, in order to obtain the outer tube 6 that satisfies the seal using the O-ring, a quartz tube satisfying the dimensional accuracy of the outer diameter can be manufactured by custom order, or a generally manufactured quartz tube can be manufactured by using a heat lathe. It must either be used for post-processing or only those that meet the dimensional accuracy must be selected.

難しくやはりコストが非常に高くなるので、実際には一
般に製造された石英管の中から外径寸法の合ったものだ
けを選別して外管6として利用している。[0013] If a quartz tube is manufactured as a special order, the cost is naturally extremely high, and the post-processing is also very difficult, and the cost is also very high. Only those having the same outer diameter are selected from the inside and used as the outer tube 6.
【0014】しかしながら、外管6は、一般に製造され

別すると非常に歩留まりが悪くのるので、どうしてもコ
ストは高くなってしまう。However, as for the outer tube 6, if only those which satisfy the dimensional accuracy of the outer diameter are selected from generally manufactured quartz tubes, the yield is extremely low, so that the cost is inevitably increased.
【0015】次に図6に示すように、接着剤9を利用し
てシールしながら外管6をジャケット蓋4に取付穴5に
嵌め合わせて取り付ける場合には、外管6の外径寸法に

英管をそのまま外管6として利用できる。Next, as shown in FIG. 6, when the outer tube 6 is fitted to the jacket cover 4 by fitting it into the mounting hole 5 while sealing using an adhesive 9, the outer diameter of the outer tube 6 is reduced. Since high precision is no longer required, a generally manufactured quartz tube can be used as it is as the outer tube 6.

不良も多くなり製造コストはやはり高くなってしまう。However, when the outer tube 6 is fitted into the mounting hole 5 by fitting the outer tube 6 to the jacket lid 4 while sealing with the adhesive 9, the application of the adhesive 9 is troublesome, and at the same time, the adhesive 9 is cured. It takes a long time to perform the process, and furthermore, the bonding failure increases, and the manufacturing cost also increases.

When the device is mounted on the device, the structure is simple, troublesome, and no defect is caused, so that the assembly cost is reduced and the device can be manufactured at a low cost.

ので、装置のメンテイナンスに費用が掛からない。In addition, the sealing effect against water leakage by the elastic seal tube is perfect, and if the elastic seal tube is made of a material resistant to ultraviolet rays such as fluoro rubber, it is difficult to deteriorate. Since the band is tightened and the sealing effect is maintained for a long period of time, the maintenance of the device is inexpensive.
