- 按照上一页的相关说明拆卸安全阀总成。
Remove the relief valve assembly as outlined on page
5.
- 从阀体镗孔内拆卸固定器。现在通过手或螺丝刀可以将止回阀模块从阀门上拆卸下来。注：第一和第二止回阀模块的阀座和弹簧是不能互换的。较重的弹簧和较小直径的阀座属于第一止回阀模块。
Remove the retainer from the body bore. The check
valve modules can now be removed from the valve by hand or with a screwdriver.
Note: The seats and springs of the first and second
check modules are not interchangeable. The heavier spring and smaller
diameter seat belong with the first check module.
- 附在阀笼上的止回阀座配置卡口型锁定装置。用一只手握住阀笼，向内推阀座并顺、反时针方向旋转阀笼。阀座，弹簧阀笼，弹簧和阀瓣总成现在已成独立的部件。
The check seats are attached to the cage with
a bayonet type locking arrangement. Holding the cage in one hand, push
the seat inward and rotate counterclockwise against the cage. The seat,
spring cage, spring and disc assembly are now individual components.
- 阀瓣总成现在可能需要清洗和重新装配，或者，根据具体情况，可能需要报废和从维修组件中取出新的进行更换。O形环应该根据需要进行清洗或更换，并且采用美国食品及药物管理局(FDA)认可的硅润滑油涂上薄薄的一层。
The disc assembly may now be cleaned and reassembled
or, depending on its condition, may be discarded and replaced with a
new assembly from the repair kit. O-rings should be cleaned or replaced
as necessary and lightly greased with the FDA approved silicon grease.
For more information refer to repair parts price list PL-RP-BPD.
- 重新组装止回阀模块。止回阀模块安装在阀体内，其阀座面对着阀门进口。在固定器能够重新放置之前，模块必须安全地放置。更换安全阀总成。
注：维修系列009通径DN65 - DN80不需要特殊的工具。
Reassemble the check valve modules. Check modules
are installed in the valve body with the seat facing the valve inlet.
The modules must be securely in place before the retainer can be replaced.
Replace relief valve assembly.
