Abstract

压力表稳压缓冲器是缓冲压力表所受脉冲压力， 提高测压精度和寿命的装置。它具有一个缓冲座，该 座一端接入测压系统管路中，另一端连接压力表头， 缓冲座腔体内具有一个起缓冲压力的芯体，通过芯体 与内腔间的空隙来减少系统压力对压力表传感元件 的脉动冲击。

Description

本实用新型属于压力表稳压装置。
公知的压力表直接接受被测压力系统压力，以指示该系统压力，系统压力的脉动使压力表传感元件承受动载荷导致测压精度和使用寿命降低。
本发明的目的是降低传入压力表中的脉动压力冲击幅值，使压力表处于稳定工作状态，读数准确，延长使用寿命。
本实用新型所涉及的压力表稳压缓冲器具有一个缓冲座（1），其一端通过下部连接管与压力系统中管道或液压块连接，缓冲座（1）另一端通过螺丝扣与压力表连接，在缓冲座（1）腔体内设有一个芯体（2），芯体（2）与缓冲座（1）内腔壁具有间隙，在芯体上设有沟槽，可以通过载压流体，压力表连接口紧密压住芯体（2），不使芯体在缓冲座（2）中移动。
本实用新型优点是降低传入压力表中脉动和冲击压力，提高使用寿命，读数准确，结构简单，形成系列产品配以不同规格压力表。
本实用新型零件皆为旋转体，易加工，材质可采用碳钢或铝合金等。
附图说明：本附图为结构示意图，1、缓冲座 2、芯体。
