The connecting sleeve 51, the steel ball 52, the valve core 53, the elastic component 54 and the clamping component 55 constitute a quick connector 5. When the pressure gauge 6 is removed, the elastic component 54 slides upward to the groove to block the steel ball 52 from sliding out. When the quick connector 61 of the pressure gauge 6 is inserted into the connecting sleeve 51, the quick connector 61 pushes the elastic component 54 downward, and the steel ball 52 is inserted into the card groove 611 to form a card connection structure, and the quick connector 61 and the elastic component 54 form a sealing structure to prevent liquid or gas from flowing to the outside from between the quick connector 61 and the elastic component 54. The pressing component 55 presses the steel ball 52 into the card groove 611, so that the quick connector 61 and the quick connector 5 are firmly connected together. The two gauge connectors 2 are connected to the low pressure gauge and the high pressure gauge through the quick connector 5.

[0021] An implementation of the elastic component 54: the elastic component 54 includes an inner spring 541 and an inner sleeve 542, the inner sleeve 542 is slidably connected to the valve core 53, the two ends of the inner spring 541 are respectively connected to the gauge connector 2 and the inner sleeve 542, and a first sealing ring 543 is provided between the inner sleeve 542 and the quick connector 61. When the pressure gauge 6 is removed, the inner spring 541 drives the inner sleeve 542 to move upward to the groove to block the steel ball 52. When the quick connector 61 of the pressure gauge 6 is inserted into the quick connector 5, the quick connector 61 pushes the inner sleeve 542 downward, and a sealing structure is formed between the two through the first sealing ring 543, and the steel ball 52 is inserted into the slot 611 of the quick connector 61 to form a clamping structure between the two.

[0022] As another embodiment of the present utility model: a connecting ring 612 is provided at the lower end of the quick connector 61, and the connecting ring 612 extends into the inner sleeve 542. A first sealing ring 543 is provided between the connecting ring 612 and the inner sleeve 542. After the steel ball 52 is inserted into the slot 611 of the quick connector 61, the inner spring 541 drives the inner sleeve 542 to move upward, so that the inner sleeve 542 abuts against the bottom of the connecting ring 612, thereby further improving the sealing performance between the quick connector 61 and the inner sleeve 542.

[0023] An implementation of the clamping assembly 55: The clamping assembly 55 includes an outer spring 551 and an outer sleeve 552. The outer side of the connecting sleeve 51 is provided with a first protrusion 511, the inner side of the outer sleeve 552 is provided with a second protrusion 5521, and the outer spring 551 is arranged between the first protrusion 511 and the second protrusion 5521. When the outer spring 551 drives the outer sleeve 552 to move upward, the outer sleeve 552 applies pressure to the steel ball 52. Secondly, the outer sleeve 552 also blocks the steel ball 52 so that it cannot come out of the groove.

[0024] Specifically, a pressing section 5522 is provided at the upper end of the outer sleeve 552. The pressing section 5522 is provided with an inclined surface, and pressure is applied to the steel ball 52 through the inclined surface. A blocking surface is provided at the upper end of the inclined surface, and the blocking surface is used to prevent the steel ball 52 from coming out of the groove.

[0025] As another embodiment of the utility model: two second sealing rings 544 are arranged between the valve core 53 and the inner sleeve 542, and the water hole 531 on the valve core 53 is arranged between the two second sealing rings 544. When the pressure gauge 6 is removed, the water hole 531 is located between the two second sealing rings 544, and the pressure gauge 6 is disconnected from the double gauge valve body 1. When the pressure gauge 6 is installed, the inner sleeve 542 is pressed downward by the quick connector 61, and the two second sealing rings 544 are located below the water hole 531, and the pressure gauge 6 is connected to the double gauge valve body 1.

[0026] Specifically, the connecting sleeve 51 is threadedly connected to the convex ring 532 of the meter connector 2 .

[0027] As another embodiment of the present invention: a boss 21 is provided at the lower end of the valve core 53 , and the boss 21 abuts against the meter connector 2 to form a sealing structure. A convex ring 532 is provided between the boss 21 and the connecting sleeve 51 .

[0028] Specifically, the valve core 53 extends downward from the boss 21 into the liquid outlet channel 22 of the meter connector 2 .

[0029] In the present invention, the outer sleeve 552 is slid downward to release the restriction on the steel ball 52, and the steel ball 52 releases the restriction on the card slot 611, and then the quick connector 61 is removed from the quick connector 5. At this time, the inner sleeve 542 moves upward to the groove position under the action of the inner spring 541 to block the steel ball 52, so as to prevent the outer sleeve 552 from pressing the steel ball 52 out of the groove when the outer sleeve 552 is loosened. The new pressure gauge 6 is inserted into the connecting sleeve 51 through the quick connector 61, and the inner sleeve 542 is pushed downward, and the steel ball 52 enters the card slot 611 of the quick connector 61. The pressing section 5522 of the outer sleeve 552 presses the steel ball 52 into the card slot 611 of the quick connector 61, ensuring that the quick connector 61 is firmly connected to the quick connector 5, thereby realizing the rapid replacement of the pressure gauge 6. In this process, the inner spring 541 drives the inner sleeve 542 to press against the connecting ring 612, and then cooperates with the first sealing ring 543 to form a sealing structure. The utility model installs a connecting device at the connection between the double-gauge valve body 1 and the pressure gauge 6, so that the pressure gauge 6 and the double-gauge valve body 1 can be quickly connected and removed. When the pressure gauge 6 is damaged, a new pressure gauge 6 can be replaced at any time, and the entire gauge valve group can be used immediately. In this way, the gauge valve group can be repeatedly used, which is beneficial to reducing maintenance costs.
