Novel surge tank

The utility model discloses a novel pressure stabilizing tank which comprises a supporting base, a supporting plate is fixedly connected to the side face of the supporting base, a rubber spring is fixedly installed at the top of the supporting plate, the pressure stabilizing tank is fixedly installed at the top of the supporting base, and the bottom of the pressure stabilizing tank is fixedly connected with the top of the rubber spring. And a hard rubber ring is movably clamped in the pressure stabilizing tank. The diaphragm is arranged on the hard rubber ring, so that the position of the diaphragm can be adjusted, and the pressure stabilizing range of the pressure stabilizing tank can be adjusted according to requirements; through cooperation of a first spring, a first movable rod and a first rubber sealing block, the device can prevent gas from flowing out of a pressurizing head due to overlarge water side pressure of a diaphragm in the using process, so that the stability of the device is ensured; and thro
