Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealed liquid circuit box technology, and in particular to a highly sealed liquid circuit box body. Background Technology
[0002] In many industrial production and experimental research fields involving liquid handling, high-sealing liquid manifolds play a crucial role. They ensure the stable transmission of liquids within a specific path, preventing liquid leakage and the intrusion of external impurities. In practical applications, high-sealing liquid manifolds typically rely on the following technologies:
[0003] 1. Box structure: Generally, high-strength, corrosion-resistant materials such as stainless steel and engineering plastics are used to make the box;
[0004] 2. Sealing connection mechanism: Various sealing components, such as rubber sealing rings and O-rings, are used to achieve tight connection between various parts of the box and with external pipelines;
[0005] 3. Liquid circuit control mechanism: Equipped with valves, pumps and other devices to control the flow of liquid in the tank. Valves are used to adjust the flow rate and direction of the liquid, as well as to open and close the liquid circuit.
[0006] Existing sealed liquid circuit boxes cannot actively seal off when a leak occurs in the internal liquid circuit. The liquid continues to flow inside the circuit, causing a continuous outflow of liquid. Since the liquids flowing in sealed liquid circuits are usually flammable, explosive, or corrosive substances, the continuous outflow of liquid can easily lead to safety accidents. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a highly airtight liquid circuit box, solving the problem that existing airtight liquid circuit boxes cannot actively seal off when a leak occurs in the internal liquid circuit, allowing the liquid to continue flowing and causing continuous leakage. Furthermore, the liquids flowing in the sealed liquid circuit are usually flammable, explosive, or corrosive substances, and the continuous leakage of liquid can easily lead to safety accidents.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A highly airtight liquid circuit enclosure includes a sealed enclosure with an installation cavity and a maintenance cavity inside. A first solenoid valve and a second solenoid valve are fixedly installed on the sealed enclosure. An installation plate for installing liquid circuit pipes and required components is slidably installed inside the sealed enclosure. A bracket is fixedly installed on the installation plate, and a metal sensor is fixedly installed on the bracket. A liquid level box is fixedly installed on the first solenoid valve. A float plate is installed inside the liquid level box, and a metal ring is fixedly installed on the outside of the float plate. A glass window for observing the liquid flow is fixedly installed on the sealed enclosure. The glass window and the sealed enclosure are connected by sealant.
[0010] Preferably, the mounting plate has through holes for fixing the liquid circuit pipes and required components.
[0011] Preferably, a threaded rod is rotatably mounted inside the sealed housing.
[0012] Preferred: Threaded connection between threaded rod and mounting plate.
[0013] Preferably, rubber gloves are symmetrically fixedly installed on the sealed box.
[0014] Preferably, a first sealing plate is slidably installed on the sealed housing.
[0015] Preferably, a second sealing plate is slidably installed on the sealed housing.
[0016] Preferably, a knob is fixedly installed on the threaded rod.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. After the liquid enters, it flows through the level box and then out. In the level box, the buoyancy of the liquid causes the float plate to float between the two metal sensors. Under normal use, the liquid entering and leaving the level box is constant. When a leak occurs in the liquid circuit, the liquid level in the level box will drop. At this time, as the liquid level drops, the float plate will drive the metal ring away from the detection range of the metal sensor. When the metal sensor can no longer detect the metal ring, it will cause the first solenoid valve and the second solenoid valve to close, sealing the liquid circuit inside the sealed box. At this time, the liquid will no longer enter or flow out, and the liquid will stop flowing. Under the action of pressure, the amount of liquid leakage will be greatly reduced, preventing the continuous flow of liquid and achieving the effect of improving the safety of the liquid circuit.
[0019] 2. When maintenance of the internal fluid circuit is required, slide the second sealing plate upward to open the maintenance chamber from the outside, then put the necessary parts and tools into the maintenance chamber, and then slide the second sealing plate downward to reset it. Insert your hands into rubber gloves, and then slide the first sealing plate from the inside of the sealed box to open the maintenance chamber from the inside. You can then take out the necessary tools and parts for maintenance, thus achieving the effect of maintaining the internal fluid circuit in a closed environment. Attached Figure Description

[0026] This application provides a highly sealed liquid circuit box, effectively solving the technical problem that existing sealed liquid circuit boxes cannot actively seal off when a leak occurs, allowing the liquid to continue flowing and causing continuous outflow. Since the liquids flowing in sealed liquid circuits are typically flammable, explosive, or corrosive, this continuous outflow can easily lead to safety accidents. In this new design, the liquid enters, flows through a level box, and then flows out. Within the level box, buoyancy causes a float plate to float between two metal sensors. Under normal use, the liquid flow into and out of the level box is constant. When a leak occurs, the liquid level in the level box drops. As the liquid level drops, the float plate moves the metal ring away from the detection range of the metal sensors. When the metal sensors can no longer detect the leak... When the metal ring is in place, it will cause the first and second solenoid valves to close, sealing the liquid path inside the sealed housing. At this time, the liquid will no longer enter or flow out, and the liquid will stop flowing. Under the action of pressure, the leakage of liquid will be greatly reduced, preventing the continuous flow of liquid and achieving the effect of improving the safety of the liquid path. When it is necessary to maintain the internal liquid path, slide the second sealing plate upward to open the maintenance chamber from the outside, and then put the maintenance parts and tools into the maintenance chamber. Then slide the second sealing plate downward to reset it. Put your hands into rubber gloves, and then slide the first sealing plate from the inside of the sealed housing to open the maintenance chamber from the inside. You can then take out the maintenance tools and parts to carry out maintenance work, achieving the effect of maintaining the internal liquid path in a closed environment.
[0027] Example
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that existing sealed liquid circuit boxes cannot be actively sealed when a leak occurs in the internal liquid circuit. The liquid continues to flow in the liquid circuit, leading to continuous outflow. Since the liquid flowing in the sealed liquid circuit is usually a flammable, explosive, or corrosive substance, the continuous outflow of liquid can easily cause safety accidents. The overall idea is as follows:
[0029] To address the problems existing in the prior art, this utility model provides a highly sealed liquid circuit box, including a sealed box 1, an installation cavity and a maintenance cavity provided inside the sealed box 1, a first solenoid valve 2 and a second solenoid valve 3 fixedly installed on the sealed box 1, and an installation plate 4 for installing liquid circuit pipes and required components slidably installed inside the sealed box 1, with a bracket 5 fixedly installed on the installation plate 4.
[0030] A metal sensor 7 is fixedly installed on the bracket 5, a liquid level box 6 is fixedly installed on the first solenoid valve 2, a float plate 8 is installed inside the liquid level box 6, a metal ring 9 is fixedly installed on the outside of the float plate 8, and a glass window 11 for observing the flow of liquid is fixedly installed on the sealed box 1; the glass window 11 and the sealed box 1 are connected by sealant.
[0031] The mounting plate 4 has through holes for fixing the liquid circuit pipes and required components. A threaded rod 12 is rotatably installed inside the sealing box 1. The threaded rod 12 is threadedly connected to the mounting plate 4. Rubber gloves 13 are symmetrically fixedly installed on the sealing box 1. A first sealing plate 14 is slidably installed on the sealing box 1. A second sealing plate 15 is slidably installed on the sealing box 1. A knob 16 is fixedly installed on the threaded rod 12.
[0032] Sealed housing 1: One-piece molded, serving as the main body of the high-sealing liquid circuit housing, it contains installation and maintenance chambers, providing a mounting base for other components. It is connected to the glass window 11 with sealant to ensure overall sealing. Simultaneously, its internal space accommodates liquid circuit pipes and related components, and provides space for liquid circuit operation.
[0033] First solenoid valve 2: It is fixedly installed on the sealed housing 1 and connected to the liquid inlet pipe. It controls the liquid flow into the liquid circuit system inside the housing and is the inlet control component for liquid entering the housing.
[0034] The second solenoid valve 3 is fixedly installed on the sealed housing 1 and connected to the liquid outflow pipe. It is responsible for controlling the liquid outflow from the housing and is the outlet control component for the liquid outflow from the housing.
[0035] Mounting plate 4: Slidably installed inside the sealed housing 1, used to install liquid pipelines and required components. Through holes on it can fix these components. It can slide up and down when the threaded rod 12 is rotated by threaded connection, so as to adjust the position of the installed components and provide flexibility for the installation and layout of the liquid system.
[0036] Bracket 5: It is fixedly installed on the mounting plate 4 and serves to connect and support the metal sensor 7, assisting the mounting plate 4 in installing and arranging related components;
[0037] Liquid level box 6: It is fixedly installed on the first solenoid valve 2 and connected in series in the liquid circuit between the first solenoid valve 2 and the second solenoid valve 3. Liquid flows through this box. A float plate 8 is installed inside. The buoyancy of the liquid keeps the float plate 8 in a specific position. At the same time, it reflects whether the liquid circuit is leaking through its own liquid level change. It is an important part of the liquid circuit leakage detection structure.
[0038] Metal sensor 7: Fixedly mounted on bracket 5, it works with float plate 8 to detect whether the liquid circuit is leaking. When float plate 8 moves metal ring 9 away from its detection range due to liquid level change, it triggers the first solenoid valve 2 and the second solenoid valve 3 to close, thus blocking the liquid circuit.
[0039] Float 8: Installed inside the liquid level box 6, it floats between two metal sensors 7 by relying on the buoyancy of the liquid. By changing its own position, it drives the metal ring 9, thereby allowing the metal sensors 7 to detect whether there is a leak in the liquid circuit.
[0040] Metal ring 9: It is fixedly installed on the outside of the float plate 8 and moves with the position of the float plate 8. When it leaves the detection range of the metal sensor 7, it indicates that the liquid circuit is leaking, thereby triggering the subsequent liquid circuit sealing action.
[0041] Glass window 11: It is fixedly installed on the sealed box 1 and connected to the sealed box 1 by sealant. It is used to observe the flow of liquid and to facilitate the operator to understand the operating status of the liquid in the box in real time.
[0042] Threaded rod 12: Rotatably installed inside the sealed housing 1, threadedly connected to the mounting plate 4, and rotates by turning the knob 16, thereby driving the mounting plate 4 to slide up and down, so as to adjust the position of the mounting plate 4 to meet the installation requirements of different liquid circuit components.
[0043] Rubber gloves 13: Symmetrically fixedly installed on the sealed housing 1, allowing operators to insert their hands into them so that the first sealing plate 14 can be slid inside the sealed housing 1 to open the maintenance chamber for internal maintenance work, thus facilitating maintenance operations;
[0044] First sealing plate 14: Slidably installed on the sealing box 1. When maintenance is required, it can be slid out from the inside of the sealing box 1 to open the maintenance chamber, making it convenient to take out the tools and parts required for maintenance.
[0045] Second sealing plate 15: Slidably installed on the sealed box 1. Sliding upwards can open the maintenance chamber from the outside, making it convenient to put in the parts and tools required for maintenance. After sliding downwards to reset, it can cooperate with rubber gloves 13 and the first sealing plate 14 to realize internal maintenance operations in a closed environment.
[0046] Knob 16: It is fixedly installed on the threaded rod 12. Rotating it can drive the threaded rod 12 to rotate, thereby adjusting the position of the mounting plate 4. It is an operating component that controls the sliding of the mounting plate 4.
[0047] Working principle:
[0048] The first step, during installation, involves connecting the first solenoid valve 2 to the liquid inlet pipe and the second solenoid valve 3 to the liquid outlet pipe. The level box 6 is then connected in series via pipes to the liquid path between the first solenoid valve 2 and the second solenoid valve 3. Turning knob 16 rotates the threaded rod 12. Since the mounting plate 4 is threadedly connected to the threaded rod 12, it will slide up and down to adjust the installation position. After the liquid enters, it flows through the level box 6 and then out. Within the level box 6, buoyancy causes the float plate 8 to float between the two metal sensors 7. During normal use… The liquid entering and exiting the level box 6 is constant. When a leak occurs in the liquid circuit, the liquid level in the level box 6 will drop. At this time, as the liquid level drops, the float plate 8 will drive the metal ring 9 away from the detection range of the metal sensor 7. When the metal sensor 7 can no longer detect the metal ring 9, it will cause the first solenoid valve 2 and the second solenoid valve 3 to close, sealing the liquid circuit inside the sealed box 1. At this time, the liquid will no longer enter or flow out, and the liquid will no longer flow. Under the action of pressure, the leakage of liquid will be greatly reduced, preventing the continuous outflow of liquid and achieving the effect of improving the safety of the liquid circuit.
[0049] The second step involves sliding the second sealing plate 15 upwards to open the maintenance chamber from the outside when maintenance is required. Then, the necessary parts and tools are placed into the maintenance chamber. The second sealing plate 15 is then slid downwards to reset the chamber. Both hands are inserted into the rubber gloves 13, and the first sealing plate 14 is slid from inside the sealed housing 1 to open the maintenance chamber from the inside. The necessary tools and parts can then be removed for maintenance, thus achieving the effect of maintaining the internal fluid circuit in a closed environment.
[0050] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
