Elastomeric seat materials are not suitable for steam service.

弹性阀座材料不适合于蒸气管道中。

The assembly shall also include two resilient seated isolation valves, four top-mounted resilient seated test cocks and an air gap drain fitting.

这种总成应该包括两个弹性阀座隔离阀，四个顶部安装弹性阀座测试旋塞和一个气隙排放接头。

Positive bubble-tight shutoff when equipped with resilient seating

如果配置的是弹性阀座,就能够具备真正的无气泡关闭功能。

The end flaps of the elastomeric seat should be flexed downward toward the valve I.D. as the body halves are being separated.

当阀体分开时，弹性阀体阀座的边缘应该朝向阀门内径弯曲。

Bubble-tight shut-off from resilient (TFE) seats

无气泡关闭功能的弹性材料(聚四氟乙烯)阀座

The resilient seal flexes and energizes, assuming the shape of the seat.

弹性密封弯曲并充满活力，保持了阀座的形状。

The lower stem is encased in a spring which forces the stem away from the seat when the valve is opened.

下阀杆包裹在一个弹簧内部，当阀门开启时，弹簧迫使阀杆离开阀座。

To clean; remove bottom plug, seat spring, strainer and seat disc.

因此要清洗，拆卸底部塞、阀座弹簧、过滤器和阀座阀瓣。

"The resilient wedge design offers bubble-tight seating, but is limited to 160 f water service."

弹性楔板结构具有无气泡阀座密封功能,但是水温最高不能超过71℃。

In order to gain access to the seat and clapper rubber ring, you must compress the spring (#3) that surrounds the clapper shaft (#1).

为了接近阀座和阀瓣橡胶环，必须压缩环绕阀瓣轴（1号）的弹簧（3号）。

Influence of Elastic Modulus toValves Designing Parameters of Hydro-Pneumatic Spring

阀片弹性模量对油气弹簧阀系设计参数的影响

The seat, spring cage, spring and disc assembly are now individual components.

此时，阀座，止回笼，弹簧和阀瓣总成就分解成都里的部件。

The lower stem is physically pulled away from the seat instead of being lifted away by the spring.

下阀杆是被从阀座上物理地推开，而不是被弹簧举起来。

Gate and globe( metal to metal) seats cannot provide bubble tight shut-off. Resilient seated butterfly valves are bubble tight by design.

闸阀和截止阀（属与金属连接）阀座不具备不透气关闭的性能。

To avoid this discharge, install a spring-loaded, rubber seated check valve ahead of the backflow assembly.

为了避免这种排放，要在防回流阀总成前面安装一个弹簧驱动、橡胶阀座的止回阀。

When the handwheel is rotated toward the open position the upper stem is moved away from the diaphragms allowing the spring to push the lower stem away from the seat.

当手轮象开启位置旋转时，上阀杆离开横膈膜，弹簧推动下阀杆离开阀座。

The assembly shall consist of two threaded-in check modules with captured springs and silicone seat discs.

这种总成应该由两个螺纹旋进、配置复位弹簧和硅酮阀座阀瓣的止回阀模块构成。

Resilient inserts are available for globe, piston and swing check discs.

可以为截止阀、活塞或旋启式止回阀阀瓣提供弹性镶嵌物。
