Description

Technical Field

[0001] The utility model relates to the technical field of water circulation, and more specifically to a full-automatic constant-pressure water replenishing and exhausting device. Background Art

[0002] The constant pressure water replenishment and exhaust device is a water circulation equipment commonly used in air conditioning and heating systems. It consists of a water replenishment component and an exhaust component. In a closed water circulation system, when a penetration problem occurs, the pressure of the water circulation system decreases. At this time, water is replenished into the water tank through the water replenishment component until the pressure inside the water circulation system returns to normal. The water replenishment component stops operating. When the water in the water circulation system is heated, the temperature rises, the volume expands, the air chamber is squeezed, and the pressure of the system increases. At this time, the gas inside the water tank needs to be discharged through the exhaust component to reduce the pressure inside the water circulation system to a normal level.

[0003] Based on the above, the inventors found that the existing water supply and exhaust devices work in a humid environment for a long time, and the control components are prone to circuit failure over time. The water supply and exhaust devices lack an effective dehumidification and drying structure, which requires frequent maintenance. Therefore, in view of this, the inventors have studied and improved the existing structure and provided a fully automatic constant pressure water supply and exhaust device in order to achieve a more practical purpose.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figure 1-4, a fully automatic constant pressure water replenishment and exhaust device, including a water tank 1, a circulation pipe 2 is fixedly connected to one side of the water tank 1, and a controller 3 and an air suction frame 6 are fixedly connected to the top surface of the water tank 1 at one end, a water pump 4 and an exhaust valve 5 are fixedly connected to the other end and the center of the top surface of the water tank 1 respectively, an air pump 7 is provided on one side of the air suction frame 6, and a connecting pipe 8 is provided in the center of the opposite surface of the air suction frame 6 and the air pump 7, one end of the water pump 4 is fixedly connected to an external water pipe 9, a moisture absorption cylinder 10 is clamped in the center of the connecting pipe 8, and extension sleeves 11 are penetrated at both ends of the connecting pipe 8, a clamping mechanism 12 is provided on the outside of the moisture absorption cylinder 10, and a threaded ring 13 and a mounting sleeve 14 are fixedly connected to both ends of the extension sleeve 11 respectively;

[0028] The clamping mechanism 12 includes two symmetrically arranged outer rods 15, both ends of the outer rods 15 are fixedly connected to positioning rods 16, and the middle part of the outer rods 15 is fixedly connected to a clamping block 17. In order to improve the installation stability of the desiccant cylinder 10 and reduce the occurrence of loosening problems, the clamping mechanism 12 is provided.

[0029] See Figure 1 The air intake frame 6 is located outside the controller 3, and an air intake hole is opened on the inner surface of the air intake frame 6. The water circulation work is carried out through the water tank 1 and the circulation pipe 2. If the pressure of the circulation system is reduced due to leakage, water is added to the water tank 1 through the water pump 4 and the external water pipe 9 to ensure the stability of the pressure of the circulation system. On the contrary, if the circulating water expands due to heating, causing the internal pressure of the water tank 1 to be too high, the water tank 1 is depressurized through the exhaust valve 5. The operation of the water replenishment component and the exhaust component is controlled by the controller 3, and then the air pump 7 is started to make the air intake frame 6 inhale the air around the controller 3. After being filtered by the moisture absorption cylinder 10 inside the connecting pipe 8, it is discharged from the output end of the air pump 7, reducing the impact of moisture on the control components and reducing circuit failure problems.

[0030] See Figure 2 The two threaded rings 13 are respectively located at both ends of the inner part of the connecting pipe 8, and the threaded rings 13 are threadedly connected to the connecting pipe 8. The extension sleeve 11 is rotated to drive the installation sleeve 14 to adjust its position through the threaded rings 13.

[0031] See Figure 2 One of the two mounting sleeves 14 is snap-connected with the input end of the air pump 7, and the other mounting sleeve 14 is snap-connected with the output end of the air suction frame 6. When the two mounting sleeves 14 are snap-connected with the input end of the air pump 7 and the output end of the air suction frame 6 respectively, the position of the connecting pipe 8 is fixed. Conversely, when the two mounting sleeves 14 are separated from the input end of the air pump 7 and the output end of the air suction frame 6 respectively, the connecting pipe 8 can be removed.

[0032] See Figure 4The two outer rods 15 are respectively located on the upper and lower sides of the connecting tube 8, the clamping block 17 is located inside the connecting tube 8, and the clamping block 17 is slidably connected to the connecting tube 8. Pulling the outer rod 15 can drive the positioning rod 16 and the clamping block 17 to move.

[0033] See Figure 4 The two positioning rods 16 on the same side are arranged in a snap-fitting manner, and the position of the outer rod 15 is fixed by the snap-fitting of the two pairs of positioning rods 16 .

[0034] See Figure 4 The middle part of the moisture absorbing cylinder 10 is provided with positioning grooves on both sides, and the clamping block 17 is clamped with the positioning groove so that the two clamping blocks 17 cooperate with each other to clamp and reinforce the moisture absorbing cylinder 10.

[0035] When in use: snap the moisture absorbing cylinder 10 into the connecting pipe 8, then press the two outer rods 15 inward to drive the snap connection of the two pairs of positioning rods 16, so that the position of the outer rod 15 is fixed. At this time, the two snap blocks 17 cooperate with each other to snap-connect and reinforce the moisture absorbing cylinder 10, then move the connecting pipe 8 to one side of the suction frame 6, rotate the extension sleeve 11, and drive the mounting sleeve 14 to adjust the position through the threaded ring 13. When the two mounting sleeves 14 are respectively snapped into the input end of the air pump 7 and the output end of the suction frame 6, the position of the connecting pipe 8 is fixed. In daily work, the water circulation work is carried out through the water tank 1 in conjunction with the circulation pipe 2. If the water circulates due to seepage, If there is a leakage problem, which causes the pressure of the circulation system to decrease, water will be added to the water tank 1 through the water pump 4 in conjunction with the external water pipe 9 to ensure the stability of the pressure of the circulation system. On the contrary, if the circulating water expands due to heating, which causes the internal pressure of the water tank 1 to be too high, the water tank 1 will be depressurized through the exhaust valve 5, and the operation of the water replenishment component and the exhaust component will be controlled by the controller 3. Then, the air pump 7 will be started to make the air suction frame 6 inhale the air around the controller 3. After being filtered by the moisture absorption cylinder 10 inside the connecting pipe 8, the air is discharged from the output end of the air pump 7, thereby reducing the influence of moisture on the control components, reducing circuit failure problems, and ensuring the normal operation of the water replenishment and exhaust device.
