DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-4 The utility model provides a technical solution: an automatic exhaust device for a closed-loop circulation system, including an air-water separation tank 1, an outlet pipe 2, a water pump 3, a check valve 4, a sight glass 5, a liquid level gauge 6, an air-water separation filler 7, a three-phase separator 8, a gas collecting chamber 9, an inlet pipe 10, a pressure gauge 11, an inlet valve 12, an exhaust pipe 13, an exhaust valve 14, a pneumatic valve 15, a degassing pump 16, a positioning card 17, a locking bolt 18, a supporting threaded rod 19, a supporting frame 20 and a locking nut 21. The bottom end of the air-water separation tank 1 is equipped with an outlet pipe 2, the outlet pipe 2 is connected to the water pump 3, and the end of the outlet pipe 2 is equipped with a check valve 4. The front of the air-water separation tank 1 A sight glass 5 is installed in the middle part, a liquid level meter 6 is installed on one side of the outer wall of the gas-water separation tank 1, an gas-water separation filler 7 is installed on the top of the gas-water separation tank 1, a three-phase separator 8 is arranged on the gas-water separation tank 1 below the gas-water separation filler 7, an air collecting chamber 9 is fixed on the top of the gas-water separation tank 1, a water inlet pipe 10 is installed on one side of the gas collecting chamber 9, a pressure gauge 11 is installed on the gas collecting chamber 9, a water inlet valve 12 is installed at the end of the water inlet pipe 10, an exhaust pipe 13 is installed at the other end of the gas collecting chamber 9, an exhaust valve 14 and a pneumatic valve 15 are installed on the top of the exhaust pipe 13, the end of the exhaust pipe 13 is connected to the degassing pump 16, and the bottom of the outer wall of the water inlet pipe 10 fits with the inner side of the positioning card 17.

[0021] In this example, a locking bolt 18 is installed on the side wall of the positioning card 17, and the bottom end of the positioning card 17 is connected and fixed to the top end of the supporting threaded rod 19. The bottom end of the supporting threaded rod 19 passes through the hole opened at the top of the supporting frame 20. The above structural design can stably install the heavier water inlet pipe 10 and its upper components, ensuring the long-term stable operation of the water inlet pipe 10 and its upper components.

[0022] The side view shape of the positioning card 17 is "U"-shaped, and the length of the positioning card 17 is greater than the width of the support frame 20. The above structural design makes the positioning card 17 easy to install, and the overall support of the positioning card 17 and the support frame 20 is stronger.

[0023] The locking bolt 18 is threadedly connected to the hole opened in the side wall of the positioning card 17. The locking bolt 18 is horizontally symmetrically distributed about the center of the water inlet pipe 10. The above structural design enables the locking bolt 18 to easily adjust the horizontal installation position and squeeze the water inlet pipe 10 from both sides to position it.

[0024] A rubber pad is fixedly installed at the end of the locking bolt 18, and the rubber pad at the end of the locking bolt 18 fits tightly against the outer wall of the water inlet pipe 10. The above structural design enables the rubber pad at the end of the locking bolt 18 to contact the outer wall of the water inlet pipe 10 over a large area, and the friction force is sufficient to ensure the squeezing and positioning effect on the water inlet pipe 10.

[0025] The support threaded rod 19 fits tightly against the inner wall of the hole opened at the top of the support frame 20. The side view shape of the support frame 20 is a "J" shape. The support threaded rod 19 is symmetrically installed with locking nuts 21 about the center of the hole opened at the top of the support frame 20. The above design enables the installation height of the support threaded rod 19 to be easily adjusted and stably fixed, and cooperates with the support frame 20 to provide stable support for the water inlet pipe 10.

[0026] Working principle: When installing the device, place the positioning card 17 close to the water inlet pipe 10 from bottom to top. When the water inlet pipe 10 fits against the inner wall of the positioning card 17, the rotationally symmetrically distributed locking bolts 18 squeeze the water inlet pipe 10 to fix it. Then push the support threaded rod 19 to slide vertically along the hole opened on the top of the support frame 20 until the positioning card 17 supports the water inlet pipe 10 to keep it horizontal. The rotationally symmetrically distributed locking nuts 21 squeeze the upper and lower end surfaces of the top of the support frame 20 to fix the positions of the support threaded rod 19 and the positioning card 17, ensuring that the water inlet pipe 10 works stably for a long time.

[0027] When the device is working as a whole, the circulating water of the closed-loop circulation system enters the gas-water separation tank 1 through the water inlet pipe 10 under the action of the pipeline pressure, passes through the gas-water separation filler 7 and the three-phase separator 8, and the gas and water are separated. The water is discharged through the water outlet pipe 2 under the action of the water pump 3, and the gas enters the gas collecting chamber 9. The pressure gauge 11 displays and transmits the pressure data in the gas-water separation tank 1. The micro-negative pressure in the gas-water separation tank 1 is maintained through the existing control system. When the gas collecting chamber 9 is at a positive pressure, the degassing pump 16 is turned on, and the liquid level is sensed and transmitted through the liquid level meter 6. When it is lower than the lower level, the drainage is stopped. When the water level is higher than the high level, stop water intake, stop water discharge when exhausting. When the water level in the gas-water separation tank 1 exceeds the middle level, according to the air pressure range displayed by the pressure gauge 11, stop water intake, then exhaust, and then pump the water to the circulating water pipeline through the water pump 3 installed on the water outlet pipe 2, and then let water in again through the water inlet pipe 10, and repeat this cycle to achieve the purpose of discharging dissolved gas in the system water. According to different closed-loop circulation systems, gas-water separators of different specifications and volumes can be designed. This is the working principle of the automatic exhaust device of the closed-loop circulation system.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
