The floating roof is an important part of an internal floating roof oil tank and is used to achieve the sealing of the operation of the internal floating roof of the oil tank. The gauge hatch is the upper and lower alignment of the gauge hatch on the tank top and the gauge hatch on the floating roof, and is used to allow the oil gauge to pass through the gauge hatch on the floating roof under the gauge hatch on the tank top for manual measurement of parameters such as the height and temperature of the oil product in the oil tank. Since the oil product is prone to volatilization loss and the oil and gas concentration in the space above the floating roof is high, the sealing performance requirements for the gauge hatch are extremely high.

[0003] At present, the traditional sealing at the gauge hatch of the internal floating roof of an oil tank will affect the gauge operation and has poor sealing performance. Since the oil product is prone to volatilization, the oil and gas concentration above the floating roof is high, which further forms an explosive mixed gas phase space, resulting in oil product evaporation loss and certain potential safety hazards.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , the present utility model provides the following technical solutions: An elastic rubber sealing structure for the dipstick opening of the internal floating roof of an oil tank, including an elastic rubber block 1, a metal fixing strip 2 is arranged on the surface of the elastic rubber block 1, a plurality of first mounting holes 3 are opened on the surface of the elastic rubber block 1, and a plurality of second mounting holes 4 are opened on the surface of the metal fixing strip 2;

[0022] It should be noted that the shape of the elastic rubber block 1 can be made into a square or a circle according to the shape of the dipstick opening;

[0023] More importantly, the position of the dipstick opening of the floating roof in the orthographic projection of the dipstick opening on the tank top and the floating roof is used for manually measuring parameters such as the height and temperature of the oil product in the oil tank from above the tank top through the dipstick opening of the floating roof. After the measurement is completed, the elastic rubber block 1 of the internal floating roof dipstick opening will automatically rebound and seal, reducing the volatilization of the oil gas below the tank to the gas phase space above the floating roof;

[0024] A fixing rivet 5 penetrates through the inner sides of the first mounting hole 3 and the second mounting hole 4. A notch 6 is opened on the surface of the elastic rubber block 1. An elastic rubber convex block 7 is arranged on the back surface of the elastic rubber block 1. A sealing strip 8 is adhered to the back surface of the elastic rubber block 1;

[0025] It should be noted that the elastic rubber convex block 7 is adapted to the size at the dipstick opening of the internal floating roof of the oil tank, and the shape of the elastic rubber convex block 7 can be made into a square or a circle according to the shape of the dipstick opening;

[0026] More importantly, the metal fixing strip 2 is used to press the elastic rubber block 1 against the edge of the dipstick opening, and the fixing rivet 5 is used to fix the metal fixing strip 2 and the elastic rubber block 1 at the dipstick opening of the internal floating roof of the oil tank.

[0027] Preferably: The number between the first mounting hole 3 and the second mounting hole 4 is matched. The elastic rubber block 1 and the metal fixing strip 2 are fitted to each other. The shape of the notch 6 is a cross shape. The sealing strip 8 and the elastic rubber block 1 are adhered with PP waterproof glue. The sealing strip 8 is sleeved on the outer wall of the elastic rubber convex block 7.

[0028] During specific use, the elastic rubber bump 7 is embedded into the gauge port of the inner floating roof of the oil tank. Then, after the metal fixing strip 2 is fitted with the elastic rubber block 1, it is fixed at the gauge port of the inner floating roof of the oil tank by using the fixing rivets 5. At this time, the sealing strip 8 will play a sealing role at the gauge port of the floating roof. And by setting the cross-shaped cut 6, when the gauging operation is carried out, the dipstick is slowly lowered from the tank top to the gauge port of the floating roof. The dipstick hammer overcomes the elastic recovery force of the elastic rubber itself by its own weight and the conical cone head, passes through the center position of its cross-shaped cut 6 and enters the oil level under the floating roof for gauging. Finally, when the dipstick is lifted and recovered, after the lifting force of the dipstick is passed through the elastic rubber block 1 by a person, the elastic rubber block 1 uses its own weight and elastic recovery force to reset and seal it, thereby avoiding the evaporation loss of the oil product and improving the safety.

[0029] Working principle: First, the elastic rubber bump 7 is embedded into the gauge port of the inner floating roof of the oil tank. Then, after the metal fixing strip 2 is fitted with the elastic rubber block 1, it is fixed at the gauge port of the inner floating roof of the oil tank by using the fixing rivets 5. At this time, the sealing strip 8 will play a sealing role at the gauge port of the floating roof. And by setting the cross-shaped cut 6, when the gauging operation is carried out, the dipstick is slowly lowered from the tank top to the gauge port of the floating roof. The dipstick hammer overcomes the elastic recovery force of the elastic rubber itself by its own weight and the conical cone head, passes through the center position of its cross-shaped cut 6 and enters the oil level under the floating roof for gauging. Finally, when the dipstick is lifted and recovered, after the lifting force of the dipstick is passed through the elastic rubber block 1 by a person, the elastic rubber block 1 uses its own weight and elastic recovery force to reset and seal it. And it is made of the elastic rubber block 1 with high elasticity and oil corrosion resistance, so that the whole has excellent elasticity and durability and can effectively prevent the volatilization of the oil product.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
