Description

Technical Field

[0001] The utility model relates to a remote regulating valve for a dry steam humidifier. Background Art

[0002] In the field of pharmaceutical controlled release and targeting, many products require constant temperature and humidity conditions for production. The dry steam humidifier used in the prior art has a set of humidity control devices in terms of control mode, which are automatically adjusted according to the set parameters (controlled by relevant programs), and this set of control devices is regulated by a set of PID. It also has a manual valve to control the amount of steam ejected. The entire system controls different humidity levels according to steam pressure fluctuations and changes in ambient temperature and humidity (due to day and night temperature differences, sunny and rainy weather, etc. outdoors). When the manual valve is not moved, the system's adjustment range is certain. When it exceeds the adjustment range, production cannot continue. The manual valve must be adjusted to meet the standard before production can continue. This manual adjustment process is a test of the worker's experience, and requires staying next to the equipment at all times, which is extremely labor-intensive. Utility Model Content

[0003] The utility model aims to provide a remote regulating valve for a dry steam humidifier, which is used to solve the problem that a manual valve requires a worker to stay beside the equipment at any time to adjust the valve, which wastes manpower.

[0004] In order to solve the above problems, the technical solution of the utility model is:

[0005] A remote regulating valve for a dry steam humidifier comprises a gear box, a valve body and a valve stem. A rotating shaft, a worm and a gear set are assembled in the gear box. A hexagonal head is arranged at one end of the rotating shaft. A motor is mounted on the gear box. The output shaft of the motor is connected to the input end of the gear set. The output end of the gear set is connected to the worm. A worm wheel meshing with the worm is assembled on the rotating shaft. The gear box is connected to the valve body through a plurality of connecting rods. An adapter is arranged between the valve body and the rotating shaft. The adapter comprises an adapter rod. A first socket and a second socket corresponding to the hexagonal head and the valve stem are respectively arranged at both ends of the adapter rod. The hexagonal head at one end of the rotating shaft and one end of the valve stem are respectively inserted into the first socket and the second socket.

[0006] The adapter also includes a circle of skirt arranged on the adapter rod, a through hole is opened at the center of the rotating shaft, a third socket coaxial with the through hole is opened at the bottom of the first socket, a spring is arranged on the adapter rod, and the two ends of the spring are respectively against the skirt and the valve body, and the spring pushes the first socket to be covered onto the hexagonal head.

[0007] It also includes a force transmission rod, one end of which is provided with a hexagonal head. The hexagonal head at one end of the force transmission rod passes through the rotating shaft and is inserted into the third plug hole.

[0008] A torsion bar which is perpendicular to the force transmission rod is fixedly connected to one end of the force transmission rod.

[0009] The beneficial effects of the utility model are:

[0010] 1. The existing manual valves are replaced with electric valves and remotely controlled, without the need for workers to be on duty, solving the problem of wasted manpower. At the same time, the modified electric valves can achieve high torque and low speed output through gear sets and worm gears, realize precise adjustment of the valves, and have a self-locking function to prevent rotation.

[0011] 2. In addition, the valve can be clutched and controlled through the adapter, which makes it convenient to switch the valve between electric and manual, realize manual emergency use of the valve, and also facilitate the resetting of the valve opening to improve the accuracy of valve opening and closing.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 4As shown, a dry steam humidifier remote regulating valve comprises a gearbox 7, a valve body 3 and a valve stem 8. A rotating shaft 9, a worm 17 and a gear set 16 are assembled in the gearbox 7. A hexagonal head is arranged at one end of the rotating shaft 9. A motor 1 is mounted on the gearbox 7. The output shaft of the motor 1 is connected to the input end of the gear set 16. The output end of the gear set 16 is connected to the worm 17. A worm wheel 18 meshing with the worm 17 is assembled on the rotating shaft 9. The gearbox 7 is connected to the valve body 3 through a plurality of connecting rods 2. An adapter is arranged between the valve body 3 and the rotating shaft 9. The adapter comprises an adapter rod 5. The first and second jacks 10 and 11 corresponding to the hexagonal head and the valve stem 8 are respectively arranged at both ends of the adapter rod. The hexagonal head at one end of the rotating shaft 9 and one end of the valve stem 8 are respectively inserted into the first and second jacks 10 and 11. The motor 1 is a servo motor 1. The first jack 10 is a hexagonal hole, the second jack 11 is a square hole, and the third jack 12 is a hexagonal hole.

[0020] When the utility model is used, after the handle of the existing manual valve is removed, the gear box 7 is connected to the valve body 3 through the connecting rod 2, and the rotating shaft 9 is connected to the valve stem 8 through the adapter, and then the motor 1 is connected to the factory DCS control system, so that the opening and closing of the valve and the opening degree of the valve can be adjusted by remotely controlling the motor 1.

[0021] In addition, compared with directly replacing manual valves with electric valves, this modification has low cost, does not require the removal of manual valves, does not require equipment shutdown, and does not require workers to be on duty, thus solving the problem of wasted manpower.

[0022] The adapter also includes a circle of skirt 6 arranged on the adapter rod 5, a through hole is opened at the center of the rotating shaft 9, a third socket 12 coaxial with the through hole is opened at the bottom of the first socket 10, and a spring 4 is arranged on the adapter rod 5, and the two ends of the spring 4 are respectively against the skirt 6 and the valve body 3, and the spring 4 pushes the first socket 10 to be covered on the hexagonal head.

[0023] It also includes a force transmission rod 14 , one end of which is provided with a hexagonal head. The hexagonal head at one end of the force transmission rod 14 passes through the rotating shaft 9 and is inserted into the third plug hole 12 .

[0024] A torsion bar 15 perpendicular to the force transmission rod 14 is fixedly connected to one end of the force transmission rod 14. The torsion bar 15 and the force transmission rod 14 form a T-shaped wrench to facilitate two-handed operation.

[0025] A plane bearing 13 is provided on the outer sleeve of the adapter rod 5, and the spring 4 pushes the plane bearing 13 to abut against the skirt 6. The plane bearing 13 can place the spring 4 for dry grinding.

[0026] In normal conditions, the spring 4 pushes the first socket 10 onto the hexagonal head, allowing the rotating shaft 9 to dock with the valve stem 8. When the remote control valve is damaged or the remote control fails, and the valve opening needs to be adjusted urgently, the hexagonal head at one end of the force transmission rod 14 can be passed through the rotating shaft 9 and inserted into the third socket 12, and the adapter rod 5 can be pushed hard to compress the spring 4, so that the adapter rod 5 is separated from the rotating shaft 9, and then the force transmission rod 14 is rotated by the torsion bar 15 to realize manual adjustment of the valve, so as to provide emergency manual use and reset the valve opening.
