Maximize the stitch length, and turn the handwheel until walking foot 1 reaches its front end position. Now, loosen screw 2 in the center shaft bell crank.

把缝迹调到最大，转动飞轮，在外压脚1前进到最前的位置拧松中轴轮紧固螺丝2。

When opening a diaphragm valve, you will feel resistance for approximately one turn, at which point most or all resistance on the handwheel will disappear.

当开启隔膜阀的时候，在大约一圈中，你会感觉到阻力，到了一圈时，大部分或所有阻力都会消失。

When the handwheel is free from resistance, the valve will provide maximum flow but will not be mistaken for a closed valve because the handwheel will turn freely.

当手轮没有阻力的时候，阀门将提供最大的流量，但因为手轮可以自由旋转，不会被误认为是关闭的阀门。

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。

Stems shall be of dezincification-resistant silicon bronze aSTM B 371 or low-zinc alloy B 99, non-asbestos packing and malleable or ductile iron handwheel .

阀杆材质是符合美国材料试验协会aSTM B371标准抗失锌现象的硅青铜,或B99低锌合金,不含石棉的填料,和可锻或球墨铸铁手轮。

The Stem Extension is made to accept the handwheel from the valve to which it is being attached. Therefore, Extensions are not supplied with a handwheel unless it is special ordered.

阀杆加长部件能够适应所连接的阀门手轮。因此,除非特别指定,否则加长部件不需要配备手轮。

The Extension consists of a length of steel tube with a coupling on the other end to attach to a handwheel or some other type of operating device.

阀杆加长部件由钢管长度和末端连接装置构成,其中一个末端连接阀门,另一端连接手轮或其他类型的操作装置。

The valve is equipped with a hand-wheel. The handwheel does not house a spring and does not wiggle or pivot.

阀门配有手轮。手轮内没有装弹簧，不会扭动或转动。

Due to the design of the valves, all sizes open with a .76 psi differential across the seat, providing the valve is properly installed (handwheel is in the open position), the valve has not been damaged (for instance, the pilot on the disc has not been bent)and no foreign particles from the line have caused the working parts to become inoperative.

根据阀门的设计要求，只要阀门的安装正确无误(手轮位于开启位置)，阀门没有损坏(例如，阀瓣上的活塞没有湾区)，管道中没有外来颗粒导致工作部件无法正常工作，那么，所有公称通径的阀门在开启状态下，流体流经阀座时都会产生0.76psi(表压)的压降。

If the operator mounting holes do not line up with the valve flange holes, the stop screw(s)should be backed off and handwheel turned until holes are aligned.

如果操作装置的安装孔与阀门法兰孔没有对应上,就要把锁定螺栓退回,旋转手轮式的螺栓孔对准为止。

The square operating nut can be substituted for the regular handwheel when an N.R.S. valve is to be installed in an inaccessible location.

如果阀门暗杆安装在难于接近的地方,则四角操作螺母能够替代普通手轮。

"If the valve is in service and the ""full open"" position, the operator handwheel should be turned until indicator pointer is at the open position and operator/bushing assembly slipped onto valve stem and adjustment procedure in paragraph 2a followed."

如果阀门处于部分开启或"完全开启"状态,就要旋转操作装置手轮,直到指示装置的指针指到开启位置为止,并把操作装置;衬套套在阀杆上,然后按照2a段程序进行调节。

Orders or inquiries for Stem Extensions to be attached to a NIBCO Valve must include the dimension from the center line of the valve waterway to the top of the handwheel .

如果要求订购或需要在尼伯科阀门上附加阀杆加长部件,请说明从阀杆水路的管道中心点到手轮顶部的长度。

The upper stem is threaded into the diaphragm retainer nut. When the handwheel is rotated to the closed position the upper stem pushes on the diaphragms, which deflect downward, forcing the lower stem against the valve seat.

上阀杆通过丝口旋在横膈膜止动螺母里。当手轮旋转到关闭位置，上阀杆推动横膈膜，横膈膜下垂，迫使下阀杆接触阀座。

Do not attempt to force beyond stops. Handwheel should turn freely over full range of travel.

手轮停止后,不要再使劲旋转。在整个活动范围内,手轮应该能够旋转自如。

Beneath the handwheel is a hexheaded externally-threaded diaphragm-retaining nut.

手轮下面是一个六角形外螺纹横膈膜止动螺母。

Recommended Opening Procedure: The diaphragm valve handwheel rotates about 1 1 /4 turns from fully open to closed.

推荐的开启程序:从彻底打开到关闭，隔膜阀手轮旋转大约11/4圈。

To prevent possible personal injuries caused by being caught in the machine, keep your fingers, head and clothes away from the handwheel , V belt and the motor while the machine is operation. In addition, place nothing around them.

为了防止被卷入机器的人身事故，缝纫机运转中请不要将手指、头发、衣服靠近皮带轮、V形皮带、马达，也不要把东西放到机器上面。

Operating Principle: The diaphragm valve is a handwheel-operated valve, utilizing a two-piece stem separated by non perforated diaphragms. These diaphragms prevent leakage along the valve stem.

运转原理:膜板阀是一种手轮型阀门，它采用两个由非穿孔横膈膜隔开的阀杆。这些横膈膜防止了沿着阀杆的泄漏。

Operating Principle: The tied-diaphragm valve is a handwheel-operated valve, utilizing a two-piece stem connected through the diaphragms.

运转原理:束缚隔膜阀是采用通过横膈膜连接的两个阀杆的手轮型阀门。

In valves, aluminum is mainly used as an exterior trim component such as a handwheel or identification tag.

在阀门上,铝主要作为外部装饰材料装饰部件,如手轮或铭牌等。

Beneath the handwheel is one set of wrench flats on a nut threaded into the valve body. This is the diaphragm-retaining nut.

在手轮下面，在一个旋进阀体的螺母上面是一套扳手面。这是横膈膜止动螺母。
