Shanghai Songjiang Shock Absorber Group Nantong Co., Ltd. will introduce to you: Why does the leakage occur when the rubber soft joint is connected with the clamping butterfly valve? Information, Songjiang Group provides customers with high-quality products, and for customers to analyze various problems related to rubber soft joints, to help customers find the reasons for the first time, and solve permanent problems.

First of all, let's look at a customer example. The following group of photos were feedback from a forging equipment manufacturer. On April 27, 2018, the customer purchased a batch of oil-resistant rubber soft joint products. Medium: hydraulic oil, pressure: less than 16 kg. During the use process after installation, there appeared the situation of rubber soft joint seal surface rupture, as follows:

As shown in the figure above, according to the analysis made by the technical engineer of our factory, the main reason is that the rubber soft joint is directly connected with the clamp-type soft sealing butterfly valve, the sealing surface of the clamp-type soft sealing butterfly valve is too small, and the rubber soft joint sealing surface is not matched with the sealing surface of the clamp-type soft sealing butterfly valve. The following is a set of photos provided by the technical department of our factory, you can compare them closely. Cover gap.
