            The
            The liquid back pressure valve
            Characteristic parameters Material Weight
            The back pressure valve generally have two purposes: 1: 背壓閥用于防止液體在重力作用下自流(或虹吸),這時候一般選用大于液體自身壓力即可,如防止液位為2米藥箱中的液體自流,可選用壓力大于0.02MPa的背壓閥,一般選用0.1MPa即可。 1: back pressure valve is used to prevent the liquid under the action of gravity gravity (or siphon), is generally used when the pressure can be greater than the liquid itself, such as to prevent the liquid level to 2 meters of liquid flowing in the chest, back pressure valve pressure is greater than 0.02MPa, generally used in the 0.1MPa. 2: 背壓閥用于穩定泵的流量,如某些泵的流量隨壓力變化較大,可在泵的出口處設置背壓閥,使泵的輸出流量穩定,這時一般選擇背壓閥的壓力為泵的實際使用壓力或略小于泵的使用壓力。 2: back pressure valve for the stability of the pump flow, such as the flow rate of the pump with the pressure change is bigger, can be set back pressure valve in the pump outlet, the pump output flow rate stability, when the general choice of back pressure valve pressure pump the actual use of the pressure or the use of slightly less than the pump pressure. 出口管道上的單向閥用于防止液體回流,背壓閥用于保持泵出口有一恒定壓力。 Check valve on the outlet pipe to prevent fluid backflow, back pressure valve to maintain a constant pressure pump outlet. Commonly used materials: PVC SUS304 SUS316 PTFE 主要特點: The main features: 1、為背壓閥的兩端管路提供壓力表 1, for the ends of pipe back pressure valve for pressure gauge 2、防止虹吸現象的發生,消除投加點壓力波動所引起的投加量變化 2, to prevent siphon phenomenon, eliminate the dosing point pressure fluctuations caused by the change of dosage 3、和脈動阻尼器配合使用減小水錘對系統的危害 3, and the pulsation damper to reduce the harm of water hammer with the use of the system 4、保護管路、彎頭、接頭,減小壓力波動的沖擊 4, the protection of pipe, elbow, joint, reduce the pressure fluctuations 5、與其他管路元件如脈動阻尼器配合使用才能發揮最大效用 5, and other piping components such as pulsation damper with the use to achieve maximum effectiveness
