Description

  The present invention relates to a fuel oil tank such as a fuel oil stove and a boiler for heating used in a cold region home, and relates to a gauge indicating a fuel oil tank installed mainly outdoors.

  The gauge of such a fuel oil tank indicates how much fuel oil has been supplied into the tank when fuel oil is supplied from the fuel oil tank filler port, or shows fuel from the fuel oil tank inlet. This is to indicate how much fuel oil remains in the tank when the oil is sent and used.

  In such a fuel oil tank, since the fuel oil is supplied to the stove or boiler by natural fall, it is installed so that the bottom surface of the tank is higher than the stove or boiler. In addition, the tank shape is thin and tall to constrain the installation location and secure the required amount.

  And the gauge provided in the upper part cannot be seen from above, and protrudes from the upper part of the tank so that the oil level indicator can be confirmed from the side. Such gauges are installed after the tank is installed in order to prevent damage during transportation due to the protruding structure.

  This type of conventional gauge is attached to a cylindrical socket whose central axis is the vertical direction of the upper surface of the tank, as shown in, for example, Utility Model Registration No. 3038222. The mounting portion is placed on the outer periphery of the socket, and is attached to the socket by a plurality of mounting screws directed inward from the outer periphery.

  In addition, a floating rod that freely rotates in the vertical direction from the lower end of the support rod is provided, a floating element is provided at the tip of the floating rod, an indicator rod is provided along the support rod, and the indicator rod moves up and down by the vertical rotation of the floating rod. It is supposed to do.

To install the gauge, insert a support rod, float float or float from the socket of the tank into the tank, place a round circular disk mounting seat on the top of the socket, and place the gauge cap over the socket. A plurality of mounting screws are fastened and fixed by sandwiching the mounting seat.
Utility model registration No. 3038222

  The fuel oil tank as described above is mainly installed when a fuel oil stove or a heating boiler is installed, and there are almost no contractors specially installing the fuel oil tank. And since the person who specializes in the stove also attaches the gauge, it is difficult to say that it is attached with sufficient care.

  The above gauges must be mounted in the correct orientation so that the floats or floats do not contact the tank inner wall when the floats are turned up and down. In other words, the float must be attached so that it is parallel to the side of the tank in plan view. The thinner the tank, the greater the risk of contact.

  There is a risk of the floating float or float contacting the inner wall when the floating float is almost horizontal.If it comes into contact, the oil level indicator will not operate and will stop while pointing to about half of the amount. There is a danger that it will overflow when it is done, or it will become empty while the tank still has fuel oil, and the stove and boiler will stop in the severe winter season.

  However, if the support rod is inserted from the socket, only the mounting seat which is a round disk can be seen, and it cannot be confirmed whether it is in the correct orientation. Therefore, if it was set in the correct orientation before insertion, it had to be inserted with care not to rotate it.

  Therefore, the present invention can be installed in the correct orientation without paying sufficient attention when inserting the gauge, and anyone can check whether the gauge is installed in the correct orientation even afterwards. It aims at providing the fuel oil tank which shows.
