Description

Technical Field

[0001] The utility model relates to the technical field of sealing cover plates, in particular to a fluid controller cover plate with good sealing performance. Background Art

[0002] With the continuous development of industrial production and the improvement of automation levels, the demand for fluid control is increasing. As key equipment, fluid controllers play an important role in the energy, chemical, pharmaceutical, aerospace and other fields. These industries have placed higher requirements on the precise control of fluid parameters such as flow, pressure, and temperature, which has promoted the continuous advancement of fluid control technology.

[0003] When installing, the fluid controller is usually installed next to the fluid. At this time, the interior of the fluid controller is easily corroded by water mist, causing water accumulation inside the fluid controller, which can easily damage the fluid controller and increase maintenance costs.

[0004] The utility model with application number CN202322262170.4 discloses a weighing controller cover, which is used in the field of weighing controller covers. It includes a cover body, and the top of the cover body is provided with an L-shaped through groove, and the number of the L-shaped through grooves is four; the utility model is provided with an L-shaped through groove on the cover body, and an L-shaped limit block is slidably connected inside the L-shaped through groove. When the cover body is buckled with the controller shell, the protrusion of the cover body enters the inside of the controller shell, and the return spring pushes the L-shaped limit block into the limit groove inside the weighing controller shell for positioning, thereby achieving the purpose of installation without the use of bolts, thereby improving the speed of installation and disassembly, and a connecting plate is installed on the cover body, which cooperates with the groove body opened at the corresponding position of the end socket, and a dustproof plate is hinged inside the groove body. The dustproof plate can prevent external dust from entering the interior of the end socket, thereby preventing dust from entering and ensuring the stability of the connection work.

[0005] This application prevents dust from entering the controller by setting up a dustproof plate, but it cannot effectively protect the water mist on the glass wall. It is difficult to prevent the fluid from passing through the glass wall when the controller is close to the glass wall, causing water mist to appear on the outer wall of the glass wall.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of the utility model is to provide a fluid controller cover with good sealing performance which can effectively solve the above technical problems.

[0008] In order to achieve the purpose of this utility model, the following technical solutions are adopted:

[0010] The sealing assembly includes a sealing shell, a positioning plate, and a fixer; a hole groove is opened in the sealing shell, and the sealing shell is plugged into the positioning plate, and the fixer is threadedly connected to the sealing shell by bolts;

[0011] A through hole is provided in the middle of the fixer, and a threaded hole is provided at the edge of the through hole.

[0012] Furthermore, the rotating assembly is composed of a display, a limiter, and a rotating member; the display is slidingly connected to the limiter, the rotating member is fixedly connected to the display, and the rotating member is rotatably connected to the sealing shell.

[0013] Furthermore, the clamping assembly includes a torsion spring and a clamping plate; the torsion spring is rotatably connected to the clamping plate, and the torsion spring enables the clamping plate to always maintain downward pressure.

[0014] Furthermore, the bottom of the display is fitted with the top of the sealing plate, and the gap is small.

[0015] Furthermore, the clamping plate may be provided with cables, or the controller may be externally connected to other wiring harnesses.

[0016] Furthermore, a groove is provided in the positioning plate to facilitate the placement of the limiter.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a fluid controller cover with good sealing performance, which positions the display through a positioning plate, so that when the display is placed horizontally, it is prevented from being on top of the positioning plate, and the midline of the short side of the positioning plate is used as the vertical line, so that the display can be perfectly immersed in the interior of the sealed shell with reference to the positioning plate, and the display is laterally packaged and positioned by a fixer to prevent the display from falling automatically due to gravity when the display is idle, thereby protecting the display.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments.

[0025] In the description of the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] like Figures 1 to 4 As shown, a fluid controller cover with good sealing performance includes: a sealing component 1 for sealing the controller, a rotating component 2 for driving the display screen on the cover to rotate, and a clamping component 3.

[0027] As is common knowledge in the art, the fundamental principle of a fluid controller is to utilize the dynamic properties of fluids to move them along a predetermined path and at a predetermined speed by designing and controlling the shape, size, position, and control methods of components such as flow channels, valves, and pumps. Commonly controlled parameters include flow rate, pressure, speed, and viscosity. Fluid controllers achieve precise regulation of fluid parameters through the coordinated operation of sensing elements (such as solenoid valves and mechanical valves) and actuators (such as pumps and pressure reducing valves).

[0028] While the controller controls the flow of fluid, when the fluid passes through the installation location of the controller, such as when cold water passes through, condensation will occur on the installation wall surface, which will cause water mist to be generated inside the controller, causing the controller to short-circuit, thereby increasing maintenance costs.

[0029] First, by installing the rotating assembly 2, the control system can be separated from the controller body, reducing the water droplet formation gap, slowing down the water droplet formation time, and at the same time, the controller body will not be affected when the water mist condenses. The rotating assembly 2 consists of a display 21, a limiter 22, and a rotating member 23; the display 21 is slidably connected to the limiter 22, the rotating member 23 is fixedly connected to the display 21, and the rotating member 23 is rotatably connected to the sealed shell 11; by sliding the limiter 22, the limiter 22 is contacted to limit the display 21, and the rotating member 23 is rotated at the same time, so that the display 21 is converted from a horizontal placement state to a vertical placement state. At this time, the display 21 does not need to be close to the controller and can still control the controller, preventing the display 21 from getting wet and causing poor performance;

[0030] At the same time, the bottom of the display 21 fits with the top of the sealing plate with a small gap. When the display 21 is not rotated, the back of the display 21 faces outward, which can protect against wind and dust, preventing dust from entering the interior of the controller and playing a dust-proof role.

[0031] The clamping assembly 3 includes a torsion spring 31 and a clamping plate 32; the torsion spring 31 is rotatably connected to the clamping plate 32, and the torsion spring 31 always keeps the clamping plate 32 under downward pressure; the clamping plate 32 can clamp cables, or the controller can be connected to other wiring harnesses; by lifting the clamping plate 32, wires such as wiring harnesses can be bundled to prevent the wires from hanging beside the glass wall when the controller is vertically attached to the glass wall, making the wires easily affected by water vapor. The clamping plate 32 is used to clamp linear objects such as cables to prevent the cables from blocking the work of the staff.

[0032] The sealing assembly 1 includes a sealing shell 11, a positioning plate 12, and a holder 13. The sealing shell 11 is provided with a hole groove, and the sealing shell 11 is plugged into the positioning plate 12. The holder 13 is threadedly connected to the sealing shell 11 by bolts. The positioning plate 12 is used to position the display 21 so that when the display 21 is placed horizontally, it is prevented from being on top of the positioning plate 12. The center line of the short side of the positioning plate 12 is used as a vertical line so that the display 21 can be perfectly immersed in the sealing shell 11 with reference to the positioning plate 12. The holder 13 is used to package the display 21 horizontally to prevent it from falling under the influence of gravity when the display 21 is idle, thereby protecting the display 21.

[0033] A through hole is provided in the middle of the fixture 13, and a threaded hole is provided at the edge of the through hole. A groove is provided in the positioning plate 12 for placing the limiter 22. By providing a through hole in the middle of the fixture 13, when disassembling the display 21, it is easier to disassemble the sealing shell 11 through the through hole for easy maintenance.

[0034] Working principle:

[0035] By sliding the limiter 22, the contact limiter 22 restricts the display 21, and at the same time rotating the rotating part 23, the display 21 is converted from the horizontal placement state to the vertical placement state. At this time, the display 21 does not need to be close to the controller, and the controller can still be controlled, preventing the display 21 from getting damp and causing poor performance. By lifting the clamping plate 32, wires such as wiring harnesses can be bundled to prevent the wires from hanging beside the glass wall when the controller is vertically attached to the glass wall, making the wires easily affected by water vapor. The clamping plate 32 is used to clamp linear objects such as cables to prevent the cables from blocking the work of the staff. The placement position of the display 21 is positioned by the positioning plate 12, so that when the display 21 is placed horizontally, it is prevented from being on the top of the positioning plate 12, and the midline of the short side of the positioning plate 12 is used as the vertical line, so that the display 21 can be perfectly immersed in the interior of the sealed shell 11 with reference to the positioning plate 12, and the display 21 is horizontally packaged and positioned by the fixer 13 to prevent the display 21 from falling automatically due to gravity when the display 21 is idle, thereby protecting the display 21.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
