Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure capable of keeping oiltightness of a gas vent valve mounted on a surface plate of an oil tank of an oil combustor or an oil storage container such as a crater, and an attachment part such as an oil meter.

[0002]

[Prior Art]

 When attaching a gas vent valve or oil meter to the surface plate of an oil tank of an oil combustor or an oil storage container such as a crater, in order to maintain the oil tightness, an oring, rubber packing, or seal is used at the joint. It was common to fix the mounting parts by caulking or screwing after applying the lubricant.

[0003]

[Problems to be solved by the device]

 In the conventional example, as described above, the joints are coated with the o-ring, the rubber packing, the sealant, etc., but if a certain sealing performance is maintained, the o-ring, the rubber packing, etc. are not always required. In many cases, it is not necessary to use expensive parts, and if the o-rings and rubber packing can be omitted, not only the direct parts price but also the manufacturing unit price can be reduced by rationalizing the manufacturing process. is there.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a mounting structure for mounting a mounting member 2 such as a gas vent valve and an oil meter mounted on a surface plate 1a of an oil storage container 1 such as an oil tank of an oil combustor. A claw 3 formed of a resin molded product and provided on the outer periphery of the mounting side 2a of the mounting component 2 and a skirt-shaped brim 5 with an appropriate distance from the claw 3 are provided, while a mounting port for the surface plate 1a is provided. 4 is provided with a bending edge 4a corresponding to the mounting side 2a of the mounting component 2, and when the mounting side 2a of the mounting component 2 is mounted in the mounting port 4, the end of the bending edge 4a and the claw 3 are engaged with each other. By stopping and pressing the lower edge of the skirt-shaped brim 5 against the surface plate 1a, an oil-tight structure of parts for a petroleum combustor is obtained.

[0005]

[Action]

 The mounting part 2 such as a gas vent valve or an oil meter is mounted on the surface plate 1a of the oil storage container 1 such as an oil tank or a crater (core tube / burner) of an oil combustor. The position is above the oil level of the oil storage container 1, and perfect airtightness is not required as in the case below the oil level. Utilizing this point, the present invention provides the surface plate 1a of the oil storage container 1 with the mounting port 4 and inserts the mounting side 2a of the mounting component 2 into the mounting port 4.

Then, the claws 3 on the mounting side 2a of the resin-made mounting component 2 to be inserted into the mounting port 4 of the surface plate 1a engage the tip of the bent edge 4a of the surface plate 1a, so that the mounting component 2 can be easily mounted. On the other hand, the mounting part 2 made of a resin molded product is provided with a skirt-shaped brim 5, and when the mounting part 2 is mounted in the mounting port 4, the lower edge of the brim 5 is The surface plate 1a is strongly pressure-bonded to maintain oil tightness.

【Example】

 The configuration will be described below with reference to the drawings showing an embodiment. FIG. 1 is an external view of a main part showing a state in which a gas vent valve is attached to an oil combustor of an upper and lower wick type, and FIG. FIG. 3 is a cross-sectional view of a main part showing a state, FIG. 3 is a cross-sectional view of a main part showing a state in which a float switch is attached, and FIG.

1 is an oil storage container such as an oil tank of an oil combustor, 1a is an upper plate of the oil storage container 1 and a surface plate such as a crater or a lid attached to the upper plate, 2 is an appropriate position of the surface plate 1a of the oil storage container 1. It is an attachment part such as a gas vent valve and oil gauge that is attached to the attachment port 4 provided, and is made of a resin molded product. Reference numeral 3 is a claw provided on the outer periphery of the mounting side 2a of the mounting component 2, and 5 is a skirt-shaped collar provided with the claw 3 at an appropriate interval. The collar 5 is a resin skirt. Therefore, the claw 3 can be slightly deformed together with the member on the mounting side 2a.

Reference numeral 4a denotes a bent edge corresponding to the mounting side 2a of the mounting component 2 mounted on the mounting port 4. The end of the bent edge 4a is engaged with the claw 3 when the mounting component 2 is inserted, Further, the brim 5 serves as a stopper when the mounting component 2 is mounted, and the tip of the brim 5 surely comes into close contact with the surface plate 1a while absorbing the error of the mounting component 2.

The mounting part 2 of the embodiment shown in FIGS. 1 and 2 shows a gas vent valve, and the mounting port 4 is provided above the oil level in the oil tank of the oil combustor, and the wick drops when extinguishing a fire. Then, when the pressure in the oil tank rises momentarily, the valve 6 opens to serve as a gas vent.

The mounting part 2 shown in FIG. 3 has a float 7 with a magnet that moves up and down as the oil level of the oil storage container 1 changes, and the reed switch 7a that opens and closes the contacts in response to magnetism detects the oil level. Control ON-OFF.

A mounting part 2 shown in FIG. 4 is an oil meter in which a float 8 that moves up and down as the oil level of the oil storage container 1 changes is attached to the tip of the lever, and the pointer portion at the other end of the lever is observed from the outside. ..

[0013]

[Effect of the device]

 According to the present invention, which has the above-described structure and operation, and the mounting parts 2 such as the gas vent valve and the oil level meter are formed of resin molded products, the claws 3 and the brim 5 can be integrally molded, which is peculiar to resin. Due to the elasticity of the tab 3, the tab 3 can be easily engaged with each other even when the tab 3 is locked to the tip of the bent edge 4a and when the tip of the collar 5 and the surface plate 1a of the oil storage container 1 are brought into contact with each other. Due to its properties, it was strongly pressure-bonded to the surface plate, and a good oil-tight structure was maintained.

Further, the collar 5 serves as a stopper when the mounting side 2a of the mounting component 2 is mounted on the mounting port 4, and in addition, the shape of the collar 5 is formed into a skirt shape, so that the skirt portion is The surface plate 1a is slightly spread and brought into contact with the surface plate 1a, which has the effect of improving the closeness. Further, even if there are variations in the dimensions of the attachment part 2 and the attachment port 4, there is an advantage that the variation is absorbed by the opening degree of the skirt portion of the collar 5.

For this reason, conventionally, it has been necessary to take a structure such as an O-ring, a rubber packing, or a sealing agent application to further secure the oil tightness, and further fix it to a mounting component. It is a versatile device that can be manufactured at low cost because it is unnecessary.
