一、进口带指挥器压力调节阀产品概述

进口带指挥器压力调节阀（美国威盾VTON），Device with a command of the pressure regulating valve，也叫氮封装置调节阀，供氮阀，泄氮阀，以阀后压力为动力源，引入阀后压力到指挥器膜片上以控制指挥器阀芯位置，改变流经指挥器阀芯的介质压力和流量，使阀门后端压力保持精确恒定的调节阀。

进口带指挥器压力调节阀压力设定在指挥器上的弹簧上实现，拧紧压缩弹簧阀后压力变大，反之则变小，操作简单因而存在方便、便捷、比一般的直接取压自力式压力调节阀精度要高；一般用于储罐氮封系统；调节和稳定储罐的氮气压力，控制精度极其灵敏，控制精度阀后能达到0.0001MPa （100pa，0.1kp)运行过程中压力可以连续调节,特别适合是控制微压场合的工况。

Device with a command of the pressure regulating valve (VTON), also known as nitrogen sealing device regulating valve, nitrogen supply valve, nitrogen relief valve, uses the pressure behind the valve as the power source, introduces the pressure behind the valve to the diaphragm of the command to control the position of the command valve core, changes the pressure and flow rate of the medium flowing through the command valve core, and maintains a precise and constant pressure at the rear end of the valve.

The pressure setting of the pressure regulating valve with a controller is achieved on the spring on the controller. After tightening the compression spring valve, the pressure increases, and vice versa, it decreases. The operation is simple, making it convenient, convenient, and more accurate than ordinary self operated pressure regulating valves; Generally used for nitrogen sealing systems in storage tanks; Adjust and stabilize the nitrogen pressure of the storage tank, with extremely sensitive control accuracy. After controlling the precision valve, it can reach 0.0001MPa (100pa, 0.1kp). During operation, the pressure can be continuously adjusted, especially suitable for controlling micro pressure situations.

二、进口带指挥器压力调节阀产品特点

（1）无需外加能源，能在无电、无气的场合工作，既方便又节约能源，降低成本。
（2）氮封装置供氮，泄氮压力设定方便，可在连续销售的条件下进行。
（3）压力检测膜片有效面积大，设定弹簧刚度小、动作灵敏、装置工作平衡。
（4）采用无填料设计，阀杆所受磨擦力小、反应迅速、控制精度高。
（5）供氮装置采用指挥器操作，减压比可达100:1，减压效果好、控制精度高。
（6）为确保储罐的安全，需在罐顶设置呼吸阀。
（7）呼吸阀公起安全作用，避免了常规氮封装置中启闭频繁易损坏的缺陷。
