一、产品简介   Product Brief
    Y系列不锈钢真空负压力表表广泛应用于石油、化工、化纤、冶金、电站等工业部门对耐蚀、抗振要求较高的工艺流程中测量各种流体介质的压力。

   Y series All stainless steel pressure gauge Widely used in petroleum, chemical industry, chemical fiber, metallurgy, power plants and other industrial sectors

    Y系列不锈钢真空负压力表的整体结构设计合理、工艺精致，具有较高的测量精确度和持久的稳定性，因此不仅可提供出口，尤为国内用户对引进*进技术装备中的同类仪表实现国产化的理想配套产品。
   Y series All stainless steel pressure gauge  The overall structure and reasonable design, fine craft, With high measurement precision and lasting stability, So not only can provide export, Especially the domestic users to the imported instrument of foreign advanced technology and equipment in the To achieve the ideal accessory products localization.

二、结构原理   The structure principle
    Y系列不锈钢真空负压力表由导压系统(包括接头、弹簧、限流螺钉等)、齿轮传动机构、示数装置(指针与度盘)和外壳(包括表壳、表盖、表玻璃等)所组成。外壳为气密型结构，能有效地?；つ诓炕馐芑肪秤跋旌臀刍嗲秩?。对于在外壳内充液(一般为硅油或甘油)的仪表，能够抗工作环境振动较剧烈和减少介质压力的脉动影响。
   Yseries All stainless steel pressure gauge By the pressure guide system (including joints, spring, limiting screws), The gear transmission mechanism, showing the number of devices (pointer and dial) and the housing (including watchcase, table covers, table glass) formed. The shell is hermetically sealed structure, Can effectively protect the internal components from environmental influences and dirty invasion. For in the shell filled with liquid (usually a silicone oil or glycerin) instrument, Resistant to environmental vibration is violent And the influence of pressure pulsation reducing medium.
