Abstract
Description
Technical Field
[0001] This utility model relates to the field of deck valve technology, and more specifically, to a self-closing deck valve for measuring oil tank level. Background Technology
[0002] Accurate measurement of oil tank levels is crucial in numerous fields, including shipping and oil storage. It not only affects the precise counting of cargo quantities, directly impacting economic efficiency, but also significantly influences maritime safety. For example, during navigation, inaccurate oil tank level measurement can lead to miscalculations of the cargo's center of gravity, affecting the ship's stability and increasing the risk of capsizing and other accidents. In oil storage facilities, precise level measurement helps in the rational allocation of storage space, preventing oil spills or insufficient storage. As a key component of the oil tank level measurement system, the performance of the deck valve directly affects the smooth operation of the entire measurement process, as well as the efficiency and safety of the operators.
[0003] Traditional oil tank level measurement deck valves present numerous inconveniences during opening and closing. When opening the valve cover, technicians typically need specific tools, such as wrenches, to apply torque directly to specific areas of the valve cover to rotate it. However, the valve cover surface may become contaminated with oil, dust, and other impurities due to prolonged exposure to the oil tank environment, reducing surface friction. During operation, slippage is highly likely when technicians apply force, requiring repeated attempts to successfully open the valve cover, significantly reducing work efficiency. Furthermore, slippage can lead to tools slipping off due to excessive force, causing damage to surrounding equipment or personnel, posing a significant safety hazard.
[0004] Therefore, this application provides a self-closing deck valve for measuring oil tank level to solve the problems mentioned in the background art. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a self-closing deck valve for measuring oil tank levels. This valve makes it easier for technicians to open the valve cover, thereby reducing the possibility of slippage and improving the efficiency of technicians.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] A self-closing deck valve for measuring oil tank level includes a connecting flange, a valve body fixedly connected to the upper end of the connecting flange, a valve cover threadedly connected to the upper end of the valve body, a connecting rod fixedly connected to the upper end of the valve cover, a through hole drilled at the outer end of the connecting rod, an adjusting rod inserted into the through hole, connecting plates fixedly connected to both ends of the adjusting rod, two symmetrical limiting grooves drilled at the upper end of the valve cover, a receiving groove drilled in the inner wall of the through hole, a top block inserted into the receiving groove, a spring fixedly connected between the top block and the bottom end of the receiving groove, and multiple evenly distributed positioning grooves drilled at the outer end of the adjusting rod. These features facilitate easier valve cover opening by technicians, reducing the possibility of slippage and improving technician efficiency.
[0010] As a further improvement of this utility model, a chain is connected between the connecting rod and the valve cover. By setting the chain, the valve cover is less likely to be lost after it is opened.
[0011] As a further improvement of this utility model, the outer end of the adjusting rod is fitted with two symmetrical contact rings made of rubber material. By setting the contact rings, it is possible to prevent the fingers of technicians from being squeezed and injured by the connecting plate when rotating the adjusting rod.
[0012] As a further improvement of this utility model: two mutually symmetrical elastic pads are fixedly connected to the inner wall of the limiting groove. The thickness of the elastic pads is greater than the gap between the connecting plate and the inner wall of the limiting groove. By setting the elastic pads, the connecting plate can be locked in the limiting groove when it is inserted into the limiting groove.
[0013] As a further improvement of this utility model, the spring is made of stainless steel and the surface of the spring is coated with anti-rust paint. By using stainless steel to make the spring and coating its surface with anti-rust paint, the spring is less prone to corrosion during long-term use, thereby improving the service life of the spring.
[0014] 3. Beneficial effects

[0016] 1. A chain connects the connecting rod to the valve cover. By setting the chain, the valve cover is less likely to be lost after it is opened.
[0017] 2. The outer end of the adjusting rod is fitted with two symmetrical contact rings made of rubber. By setting the contact rings, the technician's fingers are less likely to be squeezed and injured by the connecting plate when rotating the adjusting rod.
[0018] 3. Two mutually symmetrical elastic pads are fixedly connected to the inner wall of the limiting groove. The thickness of the elastic pads is greater than the gap between the connecting plate and the inner wall of the limiting groove. By setting the elastic pads, the connecting plate can be locked in the limiting groove when it is inserted into the limiting groove.
[0019] 4. The spring is made of stainless steel and the surface of the spring is coated with anti-rust paint. By using stainless steel to make the spring and coating its surface with anti-rust paint, the spring is less prone to corrosion during long-term use, thereby improving the service life of the spring.

[0028] Example:
[0029] Please see Figures 1-3 A self-closing deck valve for measuring oil tank level includes a connecting flange 1, a deck valve body 2 fixedly connected to the upper end of the connecting flange 1, a valve cover 3 threadedly connected to the upper end of the deck valve body 2, a connecting rod 4 fixedly connected to the upper end of the valve cover 3, a through hole 5 drilled at the outer end of the connecting rod 4, an adjusting rod 6 inserted into the through hole 5, connecting plates 7 fixedly connected to both ends of the adjusting rod 6, two mutually symmetrical limiting grooves 8 drilled at the upper end of the valve cover 3, a receiving groove 9 drilled in the inner wall of the through hole 5, a top block 10 inserted into the receiving groove 9, a spring 11 fixedly connected between the top block 10 and the bottom end of the receiving groove 9, and multiple evenly distributed positioning grooves 12 drilled at the outer end of the adjusting rod 6. This makes it easier for technicians to open the valve cover, thereby reducing the possibility of slippage when opening the valve cover and improving the work efficiency of technicians.
[0030] Please see Figures 1-2 A chain 401 connects the connecting rod 4 and the valve cover 3. By setting the chain 401, the valve cover 3 is not easily lost after it is opened. Two symmetrical contact rings 601 are sleeved on the outer end of the adjusting rod 6. The contact rings 601 are made of rubber material. By setting the contact rings 601, the fingers of the technicians are not easily squeezed and injured by the connecting plate 7 when they rotate the adjusting rod 6.
[0031] Please see Figures 2-3 Two symmetrical elastic pads 801 are fixedly connected to the inner wall of the limiting groove 8. The thickness of the elastic pads 801 is greater than the gap between the connecting plate 7 and the inner wall of the limiting groove 8. By setting the elastic pads 801, the connecting plate 7 can be locked into the limiting groove 8 when it is inserted into the limiting groove 8. The spring 11 is made of stainless steel and the surface of the spring 11 is coated with anti-rust paint. By using stainless steel to make the spring 11 and coating its surface with anti-rust paint, the spring 11 is not easy to be corroded during long-term use, thereby improving the service life of the spring 11.
[0032] Working principle: When using this device, the technician slides the adjusting rod 6 along the through hole 5 so that the positioning groove 12 is aligned with the top block 10. Figure 1and Figure 3 As shown, the technician then rotates the adjusting rod 6 along the through hole 5, causing the connecting plate 7 to rotate into the limiting groove 8. The adjusting rod 6 is then rotated horizontally, causing the valve cover 3 to rotate. When the chain 401 is reached, the connecting plate 7 is unscrewed from the limiting groove 8. The adjusting rod 6 is then slid along the through hole 5 to the connecting plate 7 at the other end. This locking operation is repeated to change the position of the adjusting rod 6, making it less likely for the chain 401 to obstruct the adjusting rod 6 from continuously rotating the valve cover 3. Compared with existing technologies, this invention makes it easier for technicians to open the valve cover, reducing the possibility of slippage and improving the technician's work efficiency.
[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
