The flange leakage is different from sand hole single-point leakage, and online leakage stoppage is generally difficult. On one hand, the pipeline flange is complex in shape and structure, and particularly a large flange cannot be simply wound with a leakage blocking belt; on the other hand, the number of leakage points of the pipeline is large, and after the side face of the flange is plugged, each flange fastening bolt becomes a new leakage point. Generally, a clamp is arranged outside a flange, and after the flange is subjected to out-of-plane circular seam twisting, holes are punched in a flange body for glue injection. The flange body structure can be destroyed by the method, and injected water easily enters a system medium to cause medium pollution or blockage of downstream equipment, so that the flange body structure cannot be used in a water system with high cleanliness requirement.
The anti-leakage device for flange as introduced in chinese patent CN201621082299.0 includes a first clamp and a second clamp locked to each other and clamped at the outer side of the flange, each clamp is composed of a semi-circular shell with a semi-circular cross section, wing plates with semi-circular cross sections for covering the pipeline extend from both sides of each semi-circular shell, each semi-circular shell has an inner concave space for placing the flange therein, a combining part extends outwards from the periphery of each inner concave space, the inner surfaces of the combining parts are mutually embedded to lock the two clamps to form a round body with a cavity, and the cavity is further provided with a positioning device for positioning the flange at a proper position of the cavity and injecting a leakage-stopping agent to cover the sealing flange to prevent leakage of the flange. The advantage of this patent lies in that its closure that can be quick is in the outside of flange, and the inside leak-stopping agent that can inject is used for sealing the flange, reaches the effect of prevention flange seepage.
However, when the above technical solutions are implemented, it is found that the above technical solutions have at least the following problems to be improved: when a traditional flange leakage-proof device or a traditional leakage-stopping device is used, the sealing materials cannot be well installed and smeared between the sealing covers and the pipelines of the flange often because accumulated water in the sealing covers overflows.
