Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel valve cores, and in particular to a stainless steel valve core airtightness testing device. Background Technology

[0002] The valve core is a valve component that enables the valve body to perform basic functions such as directional control, pressure control, or flow control by moving. The most important aspect of the valve core is ensuring its sealing effect when it is closed. Therefore, the sealing performance of the valve core needs to be tested before it leaves the factory. As a result, a stainless steel valve core airtightness testing device has emerged.

[0003] For example, in a prior art represented by application number CN202321477303.3, the main structure includes a housing and a clamping assembly. The clamping assembly is located inside the housing and includes a fixed platform, an electric lifting sleeve, a connecting plate, a first pressure block, and a threaded rod. This stainless steel valve core airtightness testing device, by incorporating the clamping assembly, allows for adjustment of the testing device according to different valve core models during use. This enables the testing device to perform sealing effect tests on different valve core models based on usage requirements. When fixing the valve core, the electric lifting sleeve is activated to push the connecting plate downwards to a suitable position. Then, the threaded rod is rotated, and the threaded rod is movably connected to the first pressure block, pushing the second pressure block to move. Simultaneously, the second pressure block is slidably limited within a groove by a slider, causing the first and second pressure blocks to adhere to both sides of the upper surface of the valve core, thereby fixing the valve core.

[0004] During use, it was found that the existing stainless steel valve core airtightness testing device is inconvenient to quickly connect and install the air inlet pipe and exhaust pipe, requiring manual installation, which leads to a waste of time. Therefore, there is an urgent need for a stainless steel valve core airtightness testing device. Utility Model Content
