Background
The vacuum flushing device is used as an important component of sponge urban facilities. The occurrence of the device enables the water pool to be desilted without inputting manpower, eliminates potential safety hazards, realizes frequent and automatic operation, avoids solidification and hardening of sediments, and ensures the effective volume of the water pool. The time consumption is short, the energy consumption is low, the external influence is small, no operation equipment exists in the pool, and the maintenance is avoided for the whole life. However, all of this is based on creating a relatively vacuum environment in the water reservoir. The vacuum valve is used as a core component for exchanging water storage chamber and external air, and the reliability of the vacuum valve will affect the flushing effect of the whole system.
The vacuum valve mainly comprises a valve body, an air bag and a cover plate, and is shown in figure 1. In the water storage chamber, in order to maintain the vacuum degree in the water storage state, the air bag in the vacuum valve is filled with high-pressure gas to expand the air bag to fill the gap between the air bag and the valve body, so that the inside of the water storage chamber is separated from the external space. With the operation of the vacuum pump, water is continuously sucked into the water storage chamber. However, in the actual use process, the leakage problem occurs occasionally due to installation reasons, so that the energy consumption of the vacuum pump is increased frequently, the vacuum degree is not up to the standard seriously, and the water storage chamber cannot meet the requirement of the water storage height during design, thereby affecting the flushing effect.
At present, the vacuum valve is mostly fixed on a concrete foundation by adopting expansion bolts, and as shown in figure 2, an electric hammer is required to drill holes in the actual field installation process. This operation is not only liable to interfere with the reinforcing bars in the concrete structure but also difficult to avoid the occurrence of fine cracks in the surface foundation. Meanwhile, in order to ensure air tightness, glue is required to be used for sealing the joint surface, secondary pouring is carried out after the pouring glue is solidified, the installation process is complicated, the requirement on the construction precision of installation personnel is high, and the installation time is long.
