An air intake and exhaust device for a water supply steady flow tank

Abstract

The invention discloses a novel air inlet and exhaust device of a water supply flow-stabilizing tank. The novel air inlet and exhaust device comprises a base, wherein support rods fixedly connected with the base are symmetrically arranged on the upper side of the base, a first rotation groove and a second rotation groove are arranged in each support rod, a first rotation shaft rotatably connectedwith the first rotation groove is inserted in the first rotation groove, a second rotation shaft rotatably connected with the second rotation groove is inserted in the second rotation groove, the first rotation shaft is positioned below the second rotation shaft, and a first rotation plate is arranged on the first rotation shaft. The novel air inlet and exhaust device of the water supply flow-stabilizing tank has the advantages that through the combined action of air pressure in a tank body and the external atmospheric pressure, when air pressure in the tank body is relatively high, a connecting rope pulls a pressure block, then air can be exhausted from an air outlet pipe, meanwhile, the exhausted air passes through a drying device, thus moisture can be eliminated, therefore, the use safety of the device is improved, when air pressure in the tank body is relatively low, under the effect of the external atmospheric pressure, the air inlet pipe is opened, air enters the tank, and the air pressure in the tank is regulated.

Description

technical field [0001] The invention relates to the technical field of secondary water supply equipment, in particular to an air intake and exhaust device of a water supply steady flow tank. Background technique [0002] The steady flow tank is also called a negative pressure tank, which contains a negative pressure eliminator, etc. It is mainly used in the current high-rise water supply equipment. It is an indispensable part of the non-negative pressure water supply equipment. The system sets a constant pressure value. If the pipe network When the pressure is higher than the set pressure value, the pressure transmitter will feed back the pipe network pressure to the frequency conversion control cabinet, and the tap water can directly reach the user pipe network through the direct supply pipeline to supply water to the user. When the pressure of the municipal pipe network changes or the water consumption of the user pipe network changes so that the pipe pressure is lower tha...

Problems solved by technology

However, the traditional inlet and exhaust device of the water supply stabilizing tank directly discharges the gas in the water into the atmosphere around the inlet and exhaust device, which has a negative impact on the surrounding environment of the water supply stabilizing tank, especially when the pressure inside the tank is high or When the intake and exhaust device is faulty, the water-containing gas will be ejected far away, and if there is electrical equipment nearby, it may have disastrous consequences
