Description

Technical Field

[0001] This utility model relates to the technical field of valve bodies for refueling wells, specifically a status display device for a T-type valve in a refueling well. Background Technology

[0002] In aviation fuel supply systems, the T-valve of the refueling well is used to control the connection between the underground pipeline network and the refueling truck, and its opening and closing status is directly related to the safety of fuel supply.

[0003] The traditional method involves spraying a colored strip or attaching an "open / closed" label to the top of the valve stem. Operators then rely on bending over to observe the position of the colored strip or the text to determine whether the valve is open. Traditional colored strip markings are difficult to identify in low light or when covered with oil. Especially in emergency oil supply scenarios, operators may cause safety accidents due to misjudging the valve status.

[0004] Alternatively, the valve body status can be indicated by setting sensors or electronic display devices, but these electronic devices are prone to failure due to fuel vapor corrosion or mechanical vibration during long-term use, and require regular maintenance and battery replacement, making them inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a status display device for a T-type valve in a refueling well, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a status display device for a T-type valve of a refueling well, configured on a valve body assembly, and coordinated with the movement of the valve stem within the valve body assembly to respond to changes in the operational state of the valve body assembly, comprising: a fixed identifier seat detachably mounted on the valve body assembly, the fixed identifier seat being used to display a first identifier; a push-floating block fixed to the valve stem and capable of moving synchronously with the valve stem, the push-floating block being configured with a movable identifier, the movable identifier being used to display a second identifier; the push-floating block also having an identifier display opening, the first identifier or the second identifier being located at the identifier display opening when the valve stem is in the first state or the second state.

[0007] The status display device for the T-type valve of the refueling well as described above: the movable marker includes a slider and an elastic element that acts on the slider and provides a lateral force to the slider; the slider cooperates with the fixed marker seat during the axial movement of the valve stem so that the first marker or the second marker is at the marker display port.

[0008] As described above, the T-valve status display device for the refueling well has a first extrusion slope formed on the fixed marking seat and a second extrusion slope formed on the slider. The first extrusion slope and the second extrusion slope fit together to convert the axial movement of the valve stem into the lateral movement of the slider.

[0009] The status display device for the T-valve of the refueling well as described above: the fixed marking base is provided with a first marking part for carrying a first marking, and the slider is provided with a second marking part for carrying a second marking, the first marking part and the second marking part are arranged vertically offset.

[0010] The status display device for the T-type valve of the refueling well as described above: the valve body assembly includes: a valve body shell, the valve stem is placed inside the valve body shell, and a fixed mark seat is detachably installed at one end of the valve body shell; a mounting base detachably connected to the other end of the valve body shell, and an elastic mechanism is formed on the inner side of the mounting base, the elastic mechanism being connected to the valve stem.

[0011] The status display device for the T-type valve of the refueling well as described above further includes a connecting seat fixed on the valve body shell and a limiting swing block rotatably mounted on the connecting seat. The limiting swing block is connected to the mounting base through a tension spring. The limiting swing block, in conjunction with the tension spring, is used to limit the upward movement of the valve stem and can be driven to rotate by a pull rope mounted on the limiting swing block, so that the limiting swing block is released from the restriction on the upward movement of the valve stem.

[0012] The status display device for the T-valve of the refueling well as described above: the elastic mechanism includes a sliding component placed in the mounting base and a push rod that passes through the sliding component and slides with the sliding component, and a spring installed in the mounting base for generating a vertical thrust on the push rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by mechanically linking the fixed marker seat, the movable marker component and the valve stem's state, the valve body state can be intuitively displayed through the setting of the first and second markers when the valve stem is in different states. At the same time, it avoids the complexity of needing to set additional sensors or electronic display devices to indicate the valve body state in the traditional method, reduces costs and improves the reliability and stability of the system.

Detailed Implementation

[0016] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0017] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0018] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0019] Please see Figures 1-9As a status display device for a T-type valve of a refueling well according to this utility model, it is configured on the valve body assembly and cooperates with the movement of the valve stem 12 in the valve body assembly to respond to changes in the action state of the valve body assembly. It includes: a fixed mark seat 6 detachably installed on the valve body assembly, the fixed mark seat 6 being used to display a first mark; a press-floating block 7 fixed to the valve stem 12 and capable of moving synchronously with the valve stem 12, the press-floating block 7 being configured with a movable mark 13, the movable mark 13 being used to display a second mark; the press-floating block 7 also has a mark display port 701, the first mark or the second mark being located at the mark display port 701 when the valve stem 12 is in the first state or the second state.

[0020] It should be noted that the first identifier is the "press" identifier; the second identifier is the "raise" identifier.

[0021] In this embodiment, when the valve body assembly is opened (the valve stem 12 is finally in the second state), the valve stem 12 moves upward, thereby driving the floating block 7 to move upward. When the floating block 7 moves upward, the movable indicator 13 moves and displays the second indicator ("raised" indicator) at the indicator display port 701. When the floating block 7 is manually pressed, the floating block 7 drives the valve stem 12 to move downward. Then the movable indicator 13 moves aside, and the floating block 7 moves toward the fixed indicator seat 6 to display the first indicator ("pressed" indicator) at the indicator display port 701.

[0022] By mechanically linking the fixed marker seat 6, the movable marker 13, and the valve stem 12, the valve body status can be intuitively displayed through the setting of the first and second markers when the valve stem 12 is in different states. This avoids the complexity of requiring additional sensors or electronic display devices to indicate the valve body status in the traditional method, reduces costs, and improves the reliability and stability of the system.

[0023] Further, please refer to Figures 4-7 The movable marker 13 includes a slider 1301 and an elastic element 1302 that acts on the slider 1301 and provides a lateral force to the slider 1301; the slider 1301 cooperates with the fixed marker seat 6 during the axial movement of the valve stem 12 so that the first marker or the second marker is located at the marker display port 701.

[0024] A first extrusion slope 602 is formed on the fixed marking seat 6, and a second extrusion slope 1303 is formed on the slider 1301. The first extrusion slope 602 and the second extrusion slope 1303 are in contact with each other to convert the axial movement of the valve stem 12 into the lateral movement of the slider 1301.

[0025] In detail, when the valve stem 12 is in the raised state, the floating block 7 is at its highest stroke. At this time, the second mark on the slider 1301 is at the mark display port 701. When the floating block 7 is pressed down, since the position of the fixed mark seat 6 remains unchanged, the first pressing slope 602 exerts a pressing force on the second pressing slope 1303, causing the slider 1301 to move laterally. When the floating block 7 moves down to the bottom of its stroke, the first mark on the fixed mark seat 6 is just exposed at the mark display port 701. When the valve stem 12 is released from its restriction and moves upward, the floating block 7 moves upward, and the slider 1301 and the elastic element 1302 move upward accordingly. During the upward movement of the slider 1301, the slider 1301 gradually moves in the opposite direction under the elastic force of the elastic element 1302. When the floating block 7 moves upward to the highest stroke, the second mark on the slider 1301 is at the mark display port 701, thus realizing two states of display.

[0026] By cooperating with the fixed marking seat 6 and the slider 1301, and with the elastic action of the elastic element 1302, the markings are accurately displayed when the floating block 7 is pressed at different stroke positions. During the movement of the floating block 7, no additional power source is required. The accurate indication of the status can be completed by relying on the mechanical relationship between the mechanical parts, which improves the reliability and stability of the equipment, while also reducing manufacturing costs and maintenance difficulty.

[0027] Furthermore, the fixed label base 6 is provided with a first label part 601 for carrying the first label, and the slider 1301 is provided with a second label part 1304 for carrying the second label. The first label part 601 and the second label part 1304 are arranged vertically offset.

[0028] Preferably, the first and second markings can be made of oil-resistant stickers, anodized layers, or embedded color blocks to meet the requirements of long-term visibility and corrosion resistance in aviation fuel environments. This embodiment does not specifically limit this.

[0029] Further, please refer to Figures 1-3 The valve body assembly includes: a valve body housing 2, with the valve stem 12 housed inside the valve body housing 2 and a fixing mark seat 6 detachably mounted on one end of the valve body housing 2; a mounting base 1 detachably connected to the other end of the valve body housing 2, the inner side of the mounting base 1 having an elastic mechanism connected to the valve stem 12; and a connecting seat 8 fixed on the valve body housing 2 and a limiting swing block 4 rotatably mounted on the connecting seat 8. The limiting swing block 4 is connected to the mounting base 1 via a tension spring 3. The limiting swing block 4, in conjunction with the tension spring 3, restricts the upward movement of the valve stem 12 and can be driven to rotate by a pull rope 5 mounted on the limiting swing block 4, so that the limiting swing block 4 is released from restricting the upward movement of the valve stem 12.

[0030] It should be noted that the end of the limiting swing block 4 facing the valve stem 12 forms a limiting head, and the valve stem 12 forms a limiting part. When the limiting head abuts against the limiting part, the valve stem 12 can be limited to move upward. When it is necessary to release the limitation on the valve stem 12, the pull rope 5 can be pulled manually to make the limiting swing rod 4 rotate clockwise so that the limiting head passes over the limiting part and is thus released from the limiting part.

[0031] Pressing the floating block 7 causes the valve stem 12 to move downward. When the valve stem 12 moves to the end of its downward stroke, the limit head re-engages in the limit part, thus fixing the position of the valve stem 12.

[0032] The elastic mechanism includes a sliding assembly 11 placed in the mounting base 1 and a push rod 10 that passes through the sliding assembly and slides with the sliding assembly 11. The push rod 10 is connected to a spring 9 installed in the mounting base 1 and used to generate a vertical thrust on the push rod 10.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
