Description

[Detailed Description of the Invention] The present invention relates to a liquid expansion thermometer that is used by being attached to a tank, cooling/heating piping, etc.

Liquid expansion thermometers that are conventionally used by being attached to tanks, cooling/heating piping, etc.
The lower part of the temperature display tube and a protection tube to protect it are connected to the lower part of a vertically long rectangular case with a glass lid on the front, which consists of a temperature display board section with a glass temperature display tube, a temperature scale, and numbers. It is configured.

Therefore, in order to prevent other objects nearby from getting in the way of installing this liquid expansion type thermometer and making it difficult to install the thermometer, the vertically long rectangular case and the protective tube are fixed in a straight line. and
Three types of thermometers were manufactured and prepared in advance: one in which the angle between the vertically long rectangular case and the protective tube was fixed at 45 degrees, and the other in which the angle between the vertically long rectangular case and the protective tube was fixed at 90 degrees. This was extremely inconvenient as I had to select the appropriate thermometer depending on the location where I would use it. Moreover, since it is impossible to bend the vertically elongated case against the protective tube,
There were disadvantages in that the temperature displayed on the temperature display board was difficult to see and the temperature could not be accurately viewed.

Furthermore, in this liquid expansion type thermometer, the length of the lower part of the temperature display tube and the length of the protection tube are prefabricated to a certain length, so for example, when the liquid expansion type thermometer is installed, It was not possible to know the temperature in deep parts.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to provide a 360°
By making it possible to freely bend the liquid inflatable thermometer in the direction of the temperature, even if there are other objects near the installation of the liquid inflatable thermometer, it can be easily installed while avoiding it. If you want to make it easier to see the temperature displayed on the screen and to see it more accurately, and also to know the temperature deep in the area where the liquid expansion thermometer is installed, change only the protective tube to a longer one. The purpose of the present invention is to provide a convenient liquid expansion type thermometer that can determine the temperature of the area.

That is, the present invention consists of a case consisting of a temperature display tube, a temperature scale, and a temperature display plate with numbers, and a flexible tube is attached to the lower part of the case with a transparent lid attached to the front surface using a cap nut, and a tightening nut is inserted into the lower part of the flexible tube. A protective tube is screwed into the tube, a part of the reed tube connected to the lower part of the temperature display tube is coiled, and a temperature sensor is attached to the lower end of the reed tube. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to the embodiments shown in the accompanying drawings, which relate to a liquid expansion type thermometer which is made by enclosing a liquid.

The present invention consists of a temperature display plate 3 displaying a temperature scale and numbers 2 on a vertically long rectangular case 1, and a temperature display tube 4 made of glass.
and a transparent lid 5 made of glass or the like on the front.
Attach the upper part of the metal flexible tube 9 to the lower part of the vertically long rectangular case 1 by screwing the female screw 8 of the cap nut 7 into the lower male screw 6 provided at the lower part of the vertically long rectangular case 1. The female screw 14 on the upper part of the metal protective tube 13 is screwed into the male screw 12 of the tightening nut 11 fitted into the cylinder 10 with the flange 10a fixed to the lower part of the metal flexible tube 9, and the temperature display tube 4 is inserted. A part of the metal lead tube 15 connected to the lower part of the metal lead tube 15 is coiled 15a, and a metal temperature sensor 16 is attached to the lower end of the metal lead tube 15. A liquid 17 such as alcohol is sealed in a metal temperature sensor 16.

Next, to explain the operation of the present invention, the male screw 18 provided on the outer periphery of the upper part of the protection tube 13 is
When installed by screwing it into a female thread provided in a heating pipe (not shown), the internal temperature is sensed by the temperature sensor 16 in the protection tube 13. Inside the tube 15 and temperature display tube 4, there is a liquid 1 such as alcohol.
7 is enclosed, it thermally expands and rises in the temperature display tube 4 and stops, or descends and stops, so the temperature can be known from the temperature scale, numeral 2.

Therefore, in the present invention, the upper part of the flexible tube 9 is attached to the lower part of the case 1 by screwing the female screw 8 of the cap nut 7 into the lower male screw 6 provided at the lower part of the case 1. A protective tube 1 is attached to a male screw 12 of a tightening nut 11 fitted into a cylinder 10 provided with a flange 10a fixed to a cylindrical body 10.
Since the female screw 14 on the upper part of the protective tube 13 is inserted, the case 1 can be bent appropriately in 360 degrees with respect to the protective tube 13 via the flexible member 9 in the middle. Therefore, even if there are other appliances near the installation of the present invention, it can be easily installed while avoiding them, and the temperature displayed on the temperature display tube 4 of the case 1 can be easily seen. , can be seen accurately.

Further, when the flexible tube 9 is bent, the lead tube 15 connected to the lower part of the temperature display tube 4 is accommodated in the flexible tube 9, so even if the lead tube 15 is bent, the lead The tube 15 will not break. Therefore, according to the present invention, depending on the installation location, there are three types: one in which the case and protection tube are fixed in a straight line as in the past, and one in which the case and protection tube are fixed at 45 degrees or 90 degrees. This completely eliminates the inconvenience of having to prepare and prepare a thermometer in advance.

In addition, in the present invention, the protective tube 1 is attached to the tightening nut 11 inserted into the lower part of the flexible tube 9.
A reed tube 15 connected to the lower part of the temperature display tube 4 is housed in the flexible tube 9, and a part of the reed tube 15 is coiled, and a temperature sensor 1 is connected to the lower end of the reed tube 15.
6 is attached and housed in the protection tube 13, so if you want to know the temperature at a deeper position than the part where the protection tube 13 is attached, remove the protection tube 13 from the tightening nut 11 and lower the reed tube 15. If the pitch of the coiled tube 15a is widened by pulling it to an appropriate length, the length of the lead tube 15 can be increased by the desired length. By attaching the protective tube 13, which is longer than the protective tube 13, to the tightening nut 11, it is possible to know the temperature in the deep part. It is easy to make and effective by changing only the long part of number 13.
