Overflow valve for improving overflow capability
The invention discloses an overflow valve for improving the overflow capability. A shell is included and internally provided with a cavity. A water inlet pipe and a water outlet pipe are arranged at the top and the bottom of the shell correspondingly, and the bottom of the water inlet pipe stretches into the cavity. The part, on the side edge of the water inlet pipe, of the top wall of the cavityis fixedly provided with a supporting piece. A lever guide column is hinged to the lower portion of the supporting piece. A seal rubber pad which is in seal fit with the bottom of the water inlet pipeis fixedly arranged at one end of the lever guide column, and the other end is provided with a balance structure body used for forming lever balance with the seal rubber pad and driving the seal rubber pad to upwards reset. In the normal situation, the seal rubber pad seals and closes the water inlet pipe under the action of the balance structure body, and when a drain valve discharges water, outside air cannot enter a water outlet of the drain valve from the water inlet pipe, and the water discharging speed is greatly increased through the siphonic effect; and when the water pressure exertedon the seal rubber pad is higher than the acting force of the balance structure body, the lever guide column drives the seal rubber pad to rotate, the water inlet pipe is opened, the overflow valve achieves the overflow function, and the overflow effect is good.
本发明公开了一种提高溢流能力的溢流阀，包括外壳，外壳的内部开设有空腔，外壳顶部和底部分别设有进水管和出水管，进水管底部伸入空腔内。空腔的顶壁在进水管的侧边固设有支撑件，支撑件的下部铰接有一杠杆导柱。杠杆导柱的一端固设有用于与进水管底部密封配合的密封胶垫，另一端设有用于与密封胶垫形成杠杆平衡并可驱动密封胶垫向上复位的平衡结构体。正常情况下，密封胶垫因平衡结构体的作用而将进水管密封关闭，排水阀在排水时，外界空气无法从进水管进入到排水阀排水口内，虹吸效应使得排水速度大幅提高；当密封胶垫受到的水压压力大于平衡结构体的作用力时，杠杆导柱带动密封胶垫旋转并打开进水管，溢流阀实现溢流功能，溢流效果好。
