Description

Technical Field

[0001] The utility model belongs to the technical field of valve detection, in particular to a gas valve body air tightness detection device. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Among them, gas valves are valves used to control gas delivery. After production is completed, they need to be tested for air tightness to ensure the air tightness of the gas valve, ensure the stability of the gas valve when delivering gas, and avoid leakage of the valve body.

[0003] A Chinese patent application (or patent) with the publication number CN221198837U discloses a valve air tightness tester, comprising: a main body with a testing station disposed in the middle; a movable structure that slides transversely in the testing station to clamp the two ends of the valve; an expansion structure with two expansion structures disposed opposite each other, one on the inner wall of one side of the testing station and the other on the movable structure; an air pressure hole disposed on the end face of the expansion structure to inject air into the valve; and an air pressure detector symmetrically disposed in the testing station and mounted on the end face of the expansion structure. This device allows valves of different specifications to be tested without replacing the sealing structure.

[0004] The above-mentioned valve air tightness testing machine is provided with a support block for placing the valve. During testing, the valve is placed on the quarter-circular support block, and then the expansion structures on both sides are close to the support block and penetrate into the valve pipe of the valve. However, because the expansion structure needs to be moved, and there is no limiting structure for the valve on the support block, when the expansion structure contacts the valve on the support block, the valve will be displaced and the docking failure will occur; and, an expansion structure for docking with the valve pipe on the valve is provided thereon, and a moving structure for pushing it to move is also installed on the expansion structure. After testing, the valves are divided into qualified and unqualified products according to their status, and thus manual differentiation and cutting are required. We provide a gas valve body air tightness testing device to solve the above-mentioned problems. Utility Model Content

[0033] The operation process of this embodiment is as follows: the driving roller 201a works, and the conveyor belt 2 is rotated through the conveying cylinder 201b thereon. When the gas valve with qualified air tightness falls on the conveyor belt 2, it can be transported away, while the gas valve with unqualified air tightness falls into the corresponding recovery box 102 for temporary storage.

[0034] Example 2

[0035] See also Figure 4 and Figure 5 On the basis of Example 1, a height adjustment component 3 and a test component 4 are further provided. By utilizing the height adjustment component 3, the height of the test component 4 can be adjusted, thereby achieving the effect of assembling the test component 4 to the valve pipe at the top of the gas valve, thereby achieving the effect of sealing the top valve pipe.

[0041] Specifically, the test component 2 5 includes a stepper motor 501 embedded in the bottom of the slide frame 301, and a pneumatic rod 3 502 is installed on the shaft end of the stepper motor 501. At the same time, a rod sleeve 2 503 is installed on the shaft end of the pneumatic rod 3 502, and an abutment plate 2 503a is installed and welded on the upper side wall of the rod sleeve 2 503. A valve tube 2 503b for cooperating with the valve tube at the lower end of the gas valve is also provided at the center of the upper side wall of the abutment plate 2 503a. At the same time, a material stripping piece 505 is also installed on the outer side of the valve tube 2 503b and the upper end of the rod sleeve 2 503. The valve tube 2 503b is also connected to the air pump 506. The material stripping piece 505 includes a pneumatic rod 4 505a, and a push plate 505b is also installed on the shaft end of the pneumatic rod 4 505a. The center of the upper side wall of the push plate 505b is connected to the abutment ring 505d through a spring 505c.

[0042] Furthermore, pneumatic rods 3 502 are installed at both ends of the left and right ends of the rod sleeve 2 503, wherein the sliding frame 301 connected to the stepping motor 501 is fixedly connected to the mounting groove 101 at the rear part of the upper side wall of the testing platform 1 by bolts, and a mounting seat 504 is also installed at the end of the other pneumatic rod 3 502, and the mounting seat 504 is fixedly connected to the mounting groove 101 at the front part of the upper side wall of the testing platform 1 by bolts, wherein the valve tube 2 503b is arranged in the abutment ring 505d, and the air pump 506 is fixedly connected to the outer wall of the rod sleeve 2 503 through the pump frame 506a.

[0043] The operation process of this embodiment is as follows: when in use, the valve tube on one end of the gas valve is inserted into the valve tube 2 503b, and the valve tube on the other end of the gas valve is set vertically upward. Then, when the valve tube 1 402b is also nested with the valve tube at the upper end of the gas valve, the air pump 506 is started, and the air pump 506 supplies gas to the valve tube 2 503b. This part of the gas is input into the gas valve through the valve tube 2 503b to test the air tightness of the gas valve. After the test is completed, if the air tightness of the gas valve is good, the pneumatic rod 3 503 retracts until the rod sleeve 2 503 is located just above the conveyor belt 2 and stops. After that, the stepping motor 501 works, which drives the pneumatic rod 3 503 to rotate at an angle of 90 degrees to 180 degrees, and then 505d, the gas valve then falls into the corresponding recovery box 102.
