[0003] A Chinese patent with announcement number CN219197613U discloses a new type of pressure stabilizing device for a high-pressure pump, which includes a pump body; a connecting component, which is arranged on one side of the pump body, and the connecting component includes a vertical pipe connected to the discharge port of the pump body; and a pressure stabilizing component, which is located on one side of the pump body, including a mounting frame installed on the ground, on which a horizontal pipe connected to the vertical pipe is arranged, and a pressure stabilizing bag connected to the horizontal pipe is vertically arranged on the horizontal pipe.

A first connecting pipe 10 is installed on the side wall of the pressure tank 5, and a steam trap 11 is installed on the first connecting pipe 10. A three-way pipe 12 is installed on the first connecting pipe 10, and the other end of the three-way pipe 12 is connected to a second connecting pipe 13, and a check valve 14 is installed on the second connecting pipe 13. A high-pressure pump 15 is connected to the second connecting pipe 13, and the high-pressure pump 15 is connected to the base 1 through a machine base. A drive motor 16 is installed on the high-pressure pump 15, and the drive motor 16 is connected to the electric control cabinet 3 through a wire. , the high-pressure pump 15 is connected to a third connecting pipe 17, the third connecting pipe 17 is connected to a fourth connecting pipe 18, a water tank 19 is installed on the base 1, the water tank 19 is fixedly connected to the fourth connecting pipe 18, and a gate valve 20 is installed on the fourth connecting pipe 18; when working, the existing pressure stabilizing device cooperates with the high-pressure pump 15 to operate stably through the pressure tank 5. After the pressure tank 5 is used for a long time, the air inside it will be reduced due to leakage and dissolution in water, so it needs to be regularly replenished. Due to the cumbersome operation, the efficiency of replenishing air is low. The high-pressure pump 15 is operated by the driving motor 16 in the high-pressure pump 15. The high-pressure pump 15 guides the water in the water tank 19 from the fourth connecting pipe 18 into the third connecting pipe 17, from the third connecting pipe 17 into the second connecting pipe 13, and then from the second connecting pipe 13 into the tee pipe 12. Most of the water is ejected from the tee pipe 12 at high pressure, and a small part enters the first connecting pipe 10, and enters the pressure tank 5 from the first connecting pipe 10. When the pressurized water enters the pressure tank 5, the air sealed in the tank is compressed. According to Boyle's gas law, the volume of the gas decreases and the pressure increases after being compressed. When the gas pressure in the pressure tank 5 reaches the same as the water pressure, the water stops entering.

[0019] The instantaneous flow rate of the high-pressure pump 15 not only changes with time, but also is discontinuous. When the high-pressure pump 15 is unstable, that is, the water output is discontinuous, the water flow pressure in the three-way pipe 12 decreases. At this time, the gas pressure in the pressure tank 5 is greater than the water pressure. The air volume in the pressure tank 5 expands and squeezes the water in the tank out of the pressure tank 5 to replenish the system. The water is stopped until the air gas pressure and the water pressure are consistent again, thereby achieving a pressure stabilization operation of the high-pressure pump 15.

[0020] During this process, a steam trap 11 is installed on the first connecting pipe 10 between the high-pressure pump 15 and the three-way pipe 12. The steam trap 11 can automatically identify gas and water, thereby achieving the purpose of automatic gas blocking and drainage; at the same time, a check valve 14 is installed on the second connecting pipe 13 between the three-way pipe 12 and the high-pressure pump 15, which prevents water from flowing back into the high-pressure pump 15 during the pressure stabilization process, thereby achieving the stability of the pressure stabilization;

[0021] During the use of the pressure tank 5, the electric contact pressure gauge 6 thereon detects the air pressure inside it all the time and sends the detected information to the electric control cabinet 3. The electric control cabinet 3 receives the signal. When the gas in the pressure tank 5 is consumed too much and the gas pressure in the pressure tank 5 is too low, the electric control cabinet 3 controls the air pump 8 and the solenoid valve 21 to open at the same time. The solenoid valve 21 opens the air duct 9, and the air pump 8 guides the air from the air duct 9 into the pressure tank 5 to realize the opening of the pressure tank 5 and replenish the gas, which is beneficial to improve the gas replenishment efficiency.

[0022] Working principle: the existing pressure stabilizing device operates stably through the pressure tank 5 and the high-pressure pump 15. After the pressure tank 5 is used for a long time, the air inside it will be reduced due to leakage and dissolution in water, so it needs to be replenished regularly. Due to the cumbersome operation, the air replenishment efficiency is low. The driving motor 16 in the high-pressure pump 15 is operated to make the high-pressure pump 15 operate. The high-pressure pump 15 guides the water in the water tank 19 from the fourth connecting pipe 18 into the third connecting pipe 17, and from the third connecting pipe 17 into the second connecting pipe 13, and then from the second connecting pipe 13 into the three-way pipe 12. Most of the water is sprayed out from the three-way pipe 12 at high pressure, and a small part enters the first connecting pipe 10, and then enters the pressure tank 5 from the first connecting pipe 10. When the pressurized water enters the pressure tank 5, the air sealed in the tank is compressed. According to Boyle's gas law, the volume of the gas decreases and the pressure increases after being compressed, until the gas pressure in the pressure tank 5 is reduced. When the pressure of the air and the water are consistent, the water intake is stopped; the instantaneous flow rate of the high-pressure pump 15 not only changes with time, but is also discontinuous. When the high-pressure pump 15 is unstable, that is, the water output is discontinuous, the water flow pressure in the three-way pipe 12 decreases, and the gas pressure in the pressure tank 5 is greater than the water pressure. The air volume in the pressure tank 5 expands to squeeze the water in the tank out of the pressure tank 5 and replenish it into the system until the air gas pressure and the water pressure are consistent again, and the drainage is stopped, thereby achieving the pressure stabilization operation of the high-pressure pump 15; in this process, a drain valve 11 is installed on the first connecting pipe 10 between the high-pressure pump 15 and the three-way pipe 12, and the drain valve 11 can automatically identify air and water, thereby achieving the purpose of automatic air blocking and drainage; at the same time, a check valve 14 is installed on the second connecting pipe 13 between the three-way pipe 12 and the high-pressure pump 15, which prevents water from flowing back into the high-pressure pump 15 during the pressure stabilization process, thereby achieving the stability of the pressure stabilization;

[0023] During the use of the pressure tank 5, the electric contact pressure gauge 6 thereon detects the air pressure inside it all the time and sends the detected information to the electric control cabinet 3. The electric control cabinet 3 receives the signal. When the gas in the pressure tank 5 is consumed too much and the gas pressure in the pressure tank 5 is too low, the electric control cabinet 3 controls the air pump 8 and the solenoid valve 21 to open at the same time. The solenoid valve 21 opens the air duct 9, and the air pump 8 guides the air from the air duct 9 into the pressure tank 5 to realize the opening of the pressure tank 5 and replenish the gas, which is beneficial to improve the gas replenishment efficiency.
