阀座

They are designed to provide a secondary seal in the event the cylinder valve develops leakage through the valve seat.

它们是设计用来在钢瓶阀门通过阀座产生泄漏的情况下提供一个二次密封。

They are designed to provide a secondary seal in the event the cylinder valve develops leakage through the valve seat.

它们是设计用来在钢瓶阀门通过阀座产生泄露的情况下提供一个二次密封。

The seat design shall be removable and not have edges that will induce seal cutting or wear at low flows.

这种阀座结构应该是可拆卸的，并且其边缘不会在低流量下促使密封割伤或磨损。

As shown in Figure 11-25, when the airflow from a time of entry, one-way valve is on the top of the seat, the air can only flow from the throttle port of export 2, throttle valve throttling traffic is limited by the size of the mouth, adjustment screw can be adjusted throttle area.

如图11-25所示，当气流从1口进入时，单向阀被顶在阀座上，空气只能从节流口流向出口2，流量被节流阀节流口的大小所限制，调节螺钉可以调节节流面积。

The shell is made of seamless steel pipe (also can be formed by steel plate roll welding), thermal oil inlet adapter, thermal oil outlet adapter, safety valve base, discharge and etc. are welded on the shell.

壳体是无缝钢管，壳体上焊有热油进、出口接管、安全阀座、压力表座、放泄口等附加零件。

3 Open the regulator and the nozzle ring ring screw fixation screws; 1.3.4 release and remove the valve cover nut; 1.3.5 screw bolts with rings at the stem, from the valve assembly of the upper part of the body perpendicular to bring devices; when the upper part of unit from the valve body will be raised when the stem or any part not allowed to have any sway movements, any shaking could damage to the valve seat.

1.3.3 拆开调节环固定螺丝和喷咀环固定螺丝； 1.3.4 松开并拆下阀盖螺母； 1.3.5 用吊环螺栓拧在阀杆上，从阀体内垂直提起组装的上部装置；当从阀体内将上部装置提出来时，不允许阀杆或任何部件有任何的摇摆动作，任何摇动都可能损坏阀座。

So that the channel immediately exit valve seat to prevent the rapid expansion of body wall and the wall suffered cavitation damage, and for Water in the needle valve, the expansion chamber diameter of 1.5 times the diameter of including pull back the export channel, including length of 8 times the diameter when subjected to cavitation can be avoided.

使紧接阀座出口端的通道急剧扩大可防止阀体壁和管壁遭受气蚀损坏，对用于水厂中的针形阀，其扩大腔室的直径为管径的1.5倍，包括出口退拔在内的通道长度为管径的8倍时，可避免遭受气蚀。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
