             功能与用途 HA-A1型安全阀在线检测仪是一种适用锅炉压力容器领域中各种弹簧式安全阀、泄压阀开启压力检测的便携式仪器.它能在生产装置不停车状况下测量安全阀的开启压力，而不需提高系统压力. 它可对在线安全阀运行中所出现的问题进行在线应急处理.诸如对开启压力不合格的安全阀进行在线重新整定，对回座后仍有泄漏的安全阀实行有效强制关闭而不改变其整定压力.

     它可对一年以上长周期运行的安全阀进行在线方式的呼吸阀“年检”和整定，以符合国家主管部门对安全阀每年至少一次的法规要求. 当安全阀在常压下进行所谓的“冷态”检测时，它可以解决如下现场实际问题： 大检修开始停车时筛选出不需要检修的 安全阀，尤其是大口径高部位阀，节省费用和工期； 校验台整定后的安全阀经运输、 减压阀安装等环节影响开启压力往往发生变化，对此，投料开车之前进行再整定； 与爆破板串联安全阀的检测； 对焊接阀现场研磨后的整定； 对各种供热、取暖锅炉在开炉前的安全阀定压 技术特点 本仪器的设计广泛吸收了迄今中外同类产品的优点，并结合现场多年的检测经验与用户的各种需求进行了重大改革，

  主要特点如下：

 1. 采用阀瓣微动法判开准则，严格符合国际标准。

 2. 检测是阀瓣不上跳，不扰动生产工况。

 3. 新颖的螺纹式夹头确保安全阀机械支架能稳固牢靠地固定在安全阀上，变径夹盘能够适应多种不同大小阀杆。

 4. 安全可靠的限位机构，限制开启高度，不扰动生产工况。

 5. 回座后有泄漏时可用强关系统将阀瓣强行关闭。高压和超高压安全阀可采用我公司特别设计的轻便液压强关系统,而不影响定压值。

 6. 液压方式的外加力系统，加力平稳，适于较大外加力场合，外加力曲线平缓，稳定。

 7. 高灵敏度的音频监听技术。

 8. 可在线热态、冷态检测安全阀开启压力。

 9. 无螺纹阀杆可采用特殊的联接夹紧系统。

 10. 采用高精密的A/D基准电源模块，保证了测量准确度。

 11. 安装方便，操作简单。

        适用范围 1、 检测过程不接触工作介质，因此，平衡阀理论上讲该仪器的使用与检测安全阀的工作介质种类及介质压、温度无关。 2、 用于各种规格型号、结构尺寸的弹簧式安全阀、泄压阀的检测。 3、 对下列几种情况检测时需慎重处理： 粘稠性较大的介质 含有固体颗粒物夹杂的介质。 深度低温的介质。 注：本仪器不能用于弹簧内装式安全阀，例如液化气漕车安全阀。 技术指标 外加提升力0∽2000kg 力传感器量程截止阀50kg、500kg 开启压力测量误差<3% 可充电锂电池组 连续使用时间4小时 使用环境温度 -10℃~80℃ 使用环境湿度<85%R•H

          Function and purpose HA-A1-type safety valve line detector is a field of boiler and pressure vessel for a variety of spring-loaded safety valve, relief valve opening pressure testing of portable equipment. It can not stop the situation in the production plant measured the opening pressure of safety valve without having to increase the system pressure. It can be on-line safety valve Yunxing issues arising in the online Emergency. Such as the failure of the safety valve opening pressure on-line re-tuning, on the back seat after the valve still leaks forced the implementation of effective closure without changing the tuning pressure. It can run more than one year long period for online safety valve of "annual inspection" and setting, to meet Plug Valvesthe national authorities on the safety valve of the regulations at least once a year. When the safety valve under normal pressure so-called "cold" test, it can solve practical problems on site as follows: Parking overhaul began to filter out when the safety valve does not require maintenance, especially in large caliber high position valve, saving costs and schedule; Check station by setting a safety valve after the delivery, installation and other sectors affected opening pressure is often changed, which, prior to re-feed drive tuning; Safety valve in series with the blasting test plate; On-site welding valve setting after grinding; Various heating, heating boiler safety valve set at the beginning of blast furnace pressure Technical Features The design of this instrument so far Reducing Valveshas drawn on the advantages of similar products abroad, combined with years of field experience and user testing needs major reforms, the main features are as follows: 1. With valve flap to open sub-micro method criteria, in strict conformity with international standards. 2. Detection is not on the disc jump, not disturb the production conditions. 3. Novel threaded chuck to ensure a solid mechanical support can be securely fixed to the valve, the adjustable chuck to adapt to different size stem. 4. Safe and reliable limit institutions to restrict the opening height, the production conditions are not disturbed. 5. Back seat leakage after strong pass system will be used to force the valve flap closure. I can use high-pressure and high pressure relief valve specially designed light company strongly Balance Valvesrelated hydraulic systems, without affecting the set pressure value. 6. Hydraulic power system, plus the way, afterburner stable, suitable for large external forces occasions, plus power curve flat and stable. 7. Highly sensitive audio monitoring technology. 8. Available online hot, cold pressure test valve open. 9. Threaded stem can be used without special connection clamping system. 10. Using high precision A / D reference Safety valves power module, ensure the accuracy of measurement. 11. Installation and easy operation. Scope 1 and the detection process does not touch the working medium, so in theory the use and testing of the equipment safety valve working media types and media pressure, independent of temperature. 2, for a variety of specifications, the structure size of spring-loaded safety valve, pressure relief valve detection. 3, detection of the following typesAPI Cast Steel Valves of situations need careful handling: Relatively high viscous media Mixture of solid particles with the medium. Temperature of medium depth. Note: This device can not be built for the spring-type safety valve, such as liquefied petroleum gas canal car safety valve. Specifications 0 ∽ 2000kg lifting force applied Force sensor range 50kg, 500kg Open the pressure measurement error of <3% Rechargeable lithium batteries 4 hours continuous use Ambient temperature -10 ℃ ~ 80 ℃ Ambient Humidity <85% R • H
