valve flap meaning in Chinese
阀瓣
Examples
- Once the pressure of the main network returns to normal , the valve flap of drainage outlet closes under pressure , first , second level check valves open , the main network return to supply water to branch pipeline
一旦主管网压力恢复正常，排污口阀瓣受压关闭，一二级止回阀打开，主管路恢复向支管供水。 - When the pressure in the tank is balanced with the atmospheric pressure , the exhalation valve flap of the respiration valve is closely cooperate with the exhalation outlet valve seat , the inhalation valve flap is closely cooperate with the inhalation outlet valve seat
当储罐内压力与大气压力平衡时，呼吸阀呼出阀瓣与呼出口阀座严密配合，吸入阀瓣与吸入口阀座严密配合。 - In order to ensure that each valve flap valve seat surface can reach the appropriate location , in valve design hinge agencies , in order to have enough plug valve kai xuan space , and the valve genuine and comprehensive engagement with the valve seat
为了确保阀瓣每次都能到达阀座面的合适位置，阀瓣设计在铰链机构，以便阀瓣具有足够有旋启空间，并使阀瓣真正的、全面的与阀座接触。 - Municipal drinking water enters from the first level check valve , passes through drainage device , second level check valve , to supply water to the water downstream , part of medium enter the lower cavity of diaphragm of drainage device , to close the valve flap of drainage device
市政饮用水从第一级止回阀进入，经过排污器、二级止回阀，向下游供水，一部分介质由导管进入排污器膜片下腔，使排污器阀瓣关闭。 - When the municipal water supply network stops , the pressure of inlet disappears , first , second level check valves close , at the same time , because the conduit do not supply pressure to the lower cavity of diaphragm of drainage device , the valve flap of the drainage device opens under the force of spring , as well as the pressure between the first , second level check valves , to discharge off the backflow medium between the two check valves , so as to play the role of anti - pollution and isolation , even if the second level check valve occurs leakage , the backflow medium will also be discharged outside , and will not flow into the main network
当市政管网停水，进口压力消失，一、二级止回阀关闭，同时由于导管不再向排污器膜片下腔供给压力，排污器的阀瓣在弹簧力和一、二级止回阀间介质压力作用下而打开，把两止回阀间回流的介质排放掉，这样起到防污隔断作用，即使第二级止回阀出现内漏，回流的介质也会经排污器排到外面，而不会流进主管网。
