[0022] The air tightness test mechanism 11 comprises an air pressure equalizing disc 1101, an equal pressure gas pipeline 1102, a fixed groove disc 1103, an air injection device 1104, a first rubber pad 1105, an air hole 1106, an air cylinder 1107, a pushing fixed ring 1108, an air pressure detection device 1109, a second rubber pad 1110 and a deflation prompt lamp 1111. One side surface of the air pressure equalizing disc 1101 is fixedly connected with the equal pressure gas pipeline 1102. One side surface of the air pressure equalizing disc 1101 is fixedly connected with the fixed groove disc 1103. One side surface of the equal pressure gas pipeline 1102 is fixedly connected with the air injection device 1104. One side surface of the air injection device 1104 is fixedly connected with the first rubber pad 1105. An upper surface of the first rubber pad 1105 is provided with the air hole 1106. One side surface of the fixed groove disc 1103 is fixedly connected with the air cylinder 1107. One side surface of the air cylinder 1107 is fixedly connected with the pushing fixed ring 1108. One side surface of the pushing fixed ring 1108 is fixedly connected with the air pressure detection device 1109. One side surface of the pushing fixed ring 1108 is fixedly connected with the second rubber pad 1110. One side surface of the pushing fixed ring 1108 is fixedly connected with the deflation prompt lamp 1111. Through the setting of the air pressure equalizing disc 1101, the equal pressure gas pipeline 1102, the fixed groove disc 1103, the air injection device 1104, the first rubber pad 1105, the air hole 1106, the air cylinder 1107, the pushing fixed ring 1108, the air pressure detection device 1109, the second rubber pad 1110 and the deflation prompt lamp 1111, when in use, the valve is placed above the first rubber pad 1105, and then the air cylinder 1107 is started. The air cylinder 1107 drives the second rubber pad 1110 to extrude and fix the valve. Since the rubber is arranged to extrude and damage the valve, the air cylinder 1107 and the bidirectional rotary motor 5 are started. The air cylinder 1107 inflates the valve to make the air cylinder 1107 full of high-pressure gas. The air pressure detection device 1109 detects the gas inside in real time. If the valve leaks, the air pressure detection device 1109 sends a signal to make the deflation prompt lamp 1111 light up. The bidirectional rotary motor 5 drives the three groups of detection units to rotate by 180 degrees to completely immerse in the liquid below. If the valve leaks due to not meeting the standards, bubbles will leak out of the liquid surface, reminding the staff to judge the advantages and disadvantages of the product. When the first three groups of valves enter the liquid detection, the staff can install and remove the valves of the other three groups of detection units, thereby saving time resources and improving the overall detection efficiency.In this process, the air pressure in the test mechanism 11 in the plate 1101, equal pressure gas pipeline 1102, fixed groove plate 1103, gas injection device 1104, air hole 1106, push fixed ring 1108 and other components work together, such as gas injection device 1104 through the air hole 1106 to the valve inflation, air pressure plate 1101 and equal pressure gas pipeline 1102 to ensure uniform distribution of air pressure.

[0023] Further, the support foot 1 is arranged at the four corners of the lower surface of the sink 2, and each group is provided with two, and the size of the water inlet 3 is consistent with the size of the water outlet 4. Through the arrangement of the support foot 1, the four corners of the lower surface of the sink 2 are arranged with a group of support feet 1 at equal intervals, and each group has two. Such layout can evenly distribute the weight of the sink 2 on each support point, effectively disperse the pressure borne by the sink 2, reduce the possibility of deformation or damage caused by excessive local stress, thereby enhancing the stability of the sink 2 as a whole, making it more stable and firmly placed on the installation position, and reducing the risk of shaking or dumping during use.

[0024] Further, the inner diameter of the water level increasing ring 8 is consistent with the size of the inner side of the sink 2, and the fixed groove plate 1103 is fixedly connected with the bidirectional rotating motor 5 through the shaft 6. Through the arrangement of the water level increasing ring 8, the height of the water level can be increased in use, so that the valves in the lower three groups of detection units can be covered by the liquid, reducing the detection error caused by different liquid coverage and other factors, and improving the accuracy and reliability of the detection result.

[0025] Further, the equal pressure gas pipeline 1102 is symmetrically provided with six groups with the central axis of the air pressure plate 1101, and the outer side of the fixed groove plate 1103 is symmetrically provided with six groups of groove holes. Through the arrangement of the fixed groove plate 1103, the six groups of groove holes on the outer side of the fixed groove plate 1103 can simultaneously place six valves for detection. In actual engineering construction valve detection work, multiple valves can be detected at a time, which greatly increases the number of detections per unit time, effectively shortens the overall detection time, improves the detection efficiency, and the symmetrical structure of the fixed groove plate 1103 makes the whole air tightness test mechanism 11 run more stably, ensures the smooth detection, improves the service life and detection precision of the equipment.

[0026] Further, the air injection device 1104 is symmetrically arranged in the fixed groove disc 1103 with six groups in the groove hole, and the air cylinder 1107 is symmetrically arranged with one group on the left and right sides of the air injection device 1104. Through the arrangement of the air cylinder 1107, in use, the air cylinder 1107 is symmetrically arranged with one group on the left and right sides of the air injection device 1104, which helps to balance the pressure on the valve during inflation. During air injection, the internal pressure of the valve gradually rises, which may generate outward pressure on the valve. The force generated by the symmetric air cylinders 1107 on both sides can balance each other, prevent the valve from being offset or damaged due to excessive unilateral pressure, and improve the safety and accuracy of detection.

[0027] Further, the push fixed ring 1108 is arranged in a telescopic structure with the first rubber pad 1105 through the air cylinder 1107, and the air hole 1106 and the air pressure detection device 1109 are arranged in a straight line. Through the arrangement of the first rubber pad 1105, the air cylinder 1107 and the push fixed ring 1108, in use, the push fixed ring 1108 is arranged in a telescopic structure with the first rubber pad 1105 through the air cylinder 1107. This design can well fix the valve. When performing air tightness detection, start the air cylinder 1107, and the push fixed ring 1108 will move towards the first rubber pad 1105, so as to tightly clamp the valve between the push fixed ring 1108 and the first rubber pad 1105, and ensure the integrity of the valve.

[0028] Further, the fixed groove disc 1103 is arranged with five groups at equal intervals on the surface of the rotating shaft 6, and the water tank 2 is fixedly connected with the water level increasing ring 8 through the bearing 7. Through the arrangement of the fixed groove disc 1103, in use, the five groups of fixed groove discs 1103 arranged at equal intervals can simultaneously detect multiple valves. In one detection process, more valve samples can be accommodated, so that more valve air tightness detection can be completed in the same time. This design of simultaneous detection of multiple groups can greatly improve the work efficiency and reduce the detection time, so that the entire construction process will not be delayed due to valve detection. The equal interval distribution on the rotating shaft 6 enables the fixed groove disc 1103 to maintain good balance during rotation, ensuring the stability of the detection process and improving the detection accuracy.

[0029] Working principle: the valve air tightness tester for engineering construction, through the valve is placed in the first rubber pad 1105 The top, then start the air cylinder 1107, air cylinder 1107 Drive the second rubber pad 1110 to the valve extrusion, the valve is fixed, due to the setting of the rubber extrusion to the valve damage, then start the air cylinder 1107 With the bidirectional rotating motor 5, the air cylinder 1107 The valve is inflated, the air cylinder 1107 Inside full of high pressure gas, the air pressure detection device 1109 Real-time detection of the gas inside, if the valve leaks, the air pressure detection device 1109 Then send a signal to the deflation prompt light 1111 Turn on, and the bidirectional rotating motor 5 Will drive three groups of detection units to rotate a half circle, so that it is completely immersed in the liquid below, if the valve is not up to standard and lead to leakage, the liquid surface will leak out of the bubble, prompting the staff to judge the pros and cons of the finished product, when the first three groups of valves enter the liquid detection, the staff can install and remove the other three groups of detection units for valve, so as to save time resources, improve the overall detection efficiency.

[0030] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
