| 摘要 |
The ball trap (2) of the present invention is configured for connection in a pipeline such that the main flow path of the fluid in the pipeline passes through the ball trap (2). The ball trap (2) includes a sieve conduit (20) with a safety-release sieve gate (22). The sieve gate (22) is displaceable between a closed position, in which cleaning balls are trapped in the ball trap (10), and an open position, in which the impedance of the fluid flowing in the pipeline is lowered. The system is configured such that the gate (22) is normally in the closed position and may be displaced to the open position for cleaning purposes or in response to a predetermined pressure differential between the upstream and downstream sides of the sieve conduit (20). |
