Description

Technical Field

[0001] This utility model relates to the technical field of diaphragm valve processing fixtures, specifically to a diaphragm valve crimping fixture. Background Technology

[0002] A diaphragm valve is a shut-off valve that uses a diaphragm as the opening and closing element to close the flow channel, cut off the fluid, and separate the valve body cavity from the valve cover cavity. The diaphragm is usually made of elastic, corrosion-resistant, and non-permeable materials such as rubber and plastic. The valve body is mostly made of plastic, fiberglass, ceramic, or metal lined with rubber. Diaphragm valves have a simple structure, good sealing and corrosion resistance, and low fluid resistance. They are often used for low-pressure, low-temperature, highly corrosive media and media containing suspended substances.

[0003] To ensure sealing, existing diaphragm valves typically place a micro-leakage ring within an annular groove to guarantee a tight seal during subsequent use. However, the current method of placing the micro-leakage ring into the groove without proper fixation can lead to displacement and reduced lifespan or performance over time. Existing methods to address this issue include adhesive bonding, which can weaken over time, causing loosening and displacement. Alternatively, manual bending with clamps can be used, but this is labor-intensive, inefficient, and results in poor crimping quality, further impacting performance. Therefore, a fixture is needed to crimp the micro-leakage ring within the diaphragm valve, ensuring its stable fixation within the annular groove and guaranteeing the valve's lifespan and performance.
