Specifically, the plug is a circular rubber pad, and the outer diameter of the circular rubber pad is larger than the inner diameter of the pressure water pipe. In order to prevent the circular rubber pad from generating excessive deformation, a reinforcing member is screwed above the circular rubber pad, and the outer contour of the reinforcing member is smaller than the inner diameter of the pressure water pipe. Furthermore, the reinforcing member is a round steel plate, and a nylon plate with a certain thickness can also be adopted.

The fixing part is provided with a supporting rod, and the top and the bottom of the supporting rod are respectively fixed on the sleeve and the pressurized water pipe through connecting pieces.

Specifically, the two support rods are symmetrically arranged; the connecting piece is two semicircular hoops connected by bolts.

The utility model has the advantages of simple structure, low production cost, convenient operation and good water stopping effect, and can be suitable for the conditions of higher water pressure and larger water quantity. The utility model realizes the blocking under pressure by the circular rubber pad which is in interference fit with the inner diameter of the water pipe under pressure, the water stopping effect is far better than the effect of blocking by adopting the air bag, and the device can be repeatedly used, has low use cost and is more economical.
