Description

Technical Field

[0001] This utility model relates to the field of valve opening and closing technology, specifically a convenient opening and closing device for apron valve well valves. Background Technology

[0002] As a crucial component of the apron fuel supply system, the manual valves inside the valve well play a vital role in critical processes such as emergency repairs, airtightness testing, and process switching. However, current operating procedures require personnel to enter the valve well for manual operation, which not only increases operational risks but also severely impacts efficiency. Entering the valve well constitutes confined space work, an environment often fraught with safety hazards, such as insufficient oxygen levels, accumulation of toxic gases, and limited space, necessitating strict approval processes and effective safety measures. This not only increases the complexity of the operating procedures but also limits rapid response capabilities.

[0003] While some advanced airports have already introduced electric valve technology, many airports still lack the conditions for electrifying their valve wells. These airports face problems such as inconvenient valve operation, long maintenance times, and a lack of alternative solutions.

[0004] Therefore, in order to meet the need for rapid valve operation in emergency situations and improve operational efficiency and safety, a convenient valve opening and closing device for apron valve wells is proposed to solve the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example:

[0017] like Figures 1-3 As shown, this utility model embodiment provides a convenient opening and closing device for apron valve well valves, including a pneumatic motor 1, a reducer 2, a handwheel connecting mechanism 3, and an assembled bracket 4; The pneumatic motor 1 is used to provide rotational torque. The pneumatic motor 1 is connected to a reversing switch via an air pipe. The reversing switch is specifically a three-position four-way reversing valve, which controls the forward rotation, reverse rotation, and stop of the pneumatic motor 1. The reversing switch is connected to a mobile air supply source via an air pipe with a self-sealing quick connector. The specific model can be selected according to actual needs.

[0018] The reducer 2 is mounted on the surface of the assembled bracket 4 and connected to the output shaft of the pneumatic motor 1 to reduce the speed and increase the torque.

[0019] The handwheel connecting mechanism 3 is connected to the output end of the reducer 2 and is used to drive the handwheel of the valve to be opened or closed to rotate. The handwheel connecting mechanism 3 includes a turntable 31 fixed to the output end of the reducer 2. The surface of the turntable 31 is provided with multiple sets of locking rods 32. The multiple sets of locking rods 32 are respectively matched with multiple spokes on the handwheel of the valve to be opened or closed. Each set of locking rods 32 consists of two rods, and the two locking rods 32 are respectively locked on both sides of the spokes on the surface of the turntable 31. Figure 1 As shown, when the pneumatic motor 1 drives the reducer 2 to rotate, and the reducer 2 drives the turntable 31 to rotate, the handwheel of the valve to be opened or closed will be rotated under the action of the lever 32, thereby realizing the rapid opening and closing of the valve.

[0020] The position of the locking rod 32 and the turntable 31 is adjustable. Specifically, several strip-shaped slots are provided on the surface of the turntable 31. The locking rod 32 is fixed in the strip-shaped slots by locking bolts. By simply adjusting the tightness of the locking bolts, the locking rod 32 can move within the strip-shaped slots, thereby adjusting the position between the two locking rods 32 to accommodate different models of handwheels.

[0021] The assembled bracket 4 includes a support frame 41 for mounting the reducer 2. Two support plates 42 are provided on both sides of the support frame 41. Four adjustable support rods 43 are respectively provided between the two support plates 42 and the two side walls of the support frame 41. Specifically, the support plates 42 are used to fix to the inner wall of the well. The adjustable support rods 43 can be telescopic rods with different locking structures (such as threaded telescopic rods and pin-positioning telescopic rods), or they can be pairs of support rods 43 composed of multiple threaded rods. Only a certain number of rods need to be added or removed according to actual needs. In this utility model, the adjustable support rods 43 are threaded rods with corresponding nuts matched on their surfaces. The inside of the support frame 41 is hollow, so it can accommodate the threaded rods of movable length. When adjusted to the required length, the nuts on the surface of the threaded rods are tightened against the support frame 41.

[0022] Working principle: When it is necessary to close the valve in an emergency, simply supply air to the pneumatic motor 1 through the air source, and the pneumatic motor 1 will drive the reducer 2 to rotate. When the reducer 2 drives the turntable 31 to rotate, under the action of the lever 32, it will drive the handwheel of the valve to be opened or closed to rotate, thereby realizing the rapid opening and closing of the valve.

[0023] This device combines rotary drive with compressed air assistance to achieve automatic valve closure, overcoming the limitations of traditional manual operation. It has a wide range of applications and a flexible design, making it suitable for valves where electrification is inconvenient, thus improving the equipment's versatility and practicality. It saves manpower and time by reducing labor costs and shortening operation time through compressed air assistance and remote operation, thereby increasing work efficiency. Operation is simple and safe; the device is easy to operate, requiring no complex training, while ensuring the stability and safety of the valve closing process.

[0024] The solution should also be forward-looking, capable of solving the problem of rapid valve closure in airport valve wells where there is no possibility of electrification, and promoting the development trend of electric valves in apron valve wells in domestic airports, driving domestic airports towards a more intelligent and automated direction.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
