The utility model relates to industrial
automation technical field, proposes a kind of FGH entrance bypass pipeline, including two water pipes of switch valve and being set to its both sides, the both sides of switch valve are inserted with inserting
pipe, and the one end of
water pipe is inserted between inserting
pipe, connecting
assembly is set on the outside wall of inserting
pipe, and
water pipe is fixedly connected between connecting
assembly and switch valve, two sealing components are symmetrically set on the outside wall of inserting pipe, and the outside wall of two sealing components respectively with switch valve and
water pipe between contact, the inside wall of inserting pipe is fixedly installed with
fixed frame, through the sealing component on inserting pipe, the tiny gap between inserting pipe and water pipe and switch valve can be effectively filled, prevent fluid, gas or other medium leakage, ensure the sealing property of
system, while again under the action of
fixed frame and
conical shell, the pressure
shock wave generated by
water hammer can be dispersed, reduce the
impact force of
water flow, reduce the damage of
water hammer to water pipe.
