微信自动退出是什么回事

微信自动退出，考虑原因一是微信版本过低，与系统不兼容所造成，可以通过更新微信即可解决问题；考虑原因二是手机内存不足，可以通过清理内存即可。

具体操作如下：

情况一：微信版本过低，更新最新版即可。

1、在“微信”下方的菜单栏，点击“我”。

你好,看您对阀门的英文翻译很熟,可以帮我翻译下吗?

size unit下IN NS 应该是美标 英寸，BALL VALVE,CL150,RF,TI ASME B367 GR C2 BODY TI TRIM (PPL) SEATS ，球阀，150磅级，RF法兰，阀体钛材TI ASME B367 GR C2 这个是标准号，阀座TI TRIM (PPL)也是钛材的，(FULL)PORT 全通径，WRENCH CP MSS-SP-72 ASME B16.5，采用手柄操作，手柄的制造、安装遵循MSS-SP-72 ASME B16.5标准，SP-W TVGRAP GASKET 阀体垫片SP-W TVGRAP 这个好像是一种特殊材料编号，需要问工厂核实，GRAP PACKING 石墨填料。REMARK下这些东西应该是一些技术文件代号。
