用途 A46F, Ax46F (Y) pilot operated safety valve

先导式安全泄压阀 是一种新颖结构的 安全阀 . 主要用于石油天然气、化工、电力、冶金和城市燃气等领域,是受压设备、容器或管路上的最佳超压保护装置,其主要特点是变弹簧直接作用为导阀间接作用,提高了运行的灵敏度,而且精度高,重套筒活塞式,双重密封阀座结构,动作精度高,重复性好,回座快,不泄漏,能带高背压排放,工作寿命长,工作稳定可靠,它还可在线调校,反复启跳排放后, A46F pilot-operated safety relief valve is a new type of safety valve . It is mainly used in oil and gas, chemical, power, metallurgy and city gas fields. It is the best overpressure protection device for pressure equipment, vessels or pipelines. Its main feature is that the direct action of the spring is changed to the indirect action of the pilot valve, which improves the sensitivity of the operation, and has high accuracy. The heavy-sleeve piston type and double-sealed valve seat structure have high accuracy, good repeatability, fast return, and no leakage. It can discharge with high back pressure, long working life, stable and reliable operation, it can also be adjusted online, after repeated start-up and discharge, It can still return to the seat automatically, close the strict operation and easy to maintain.

结构特性: Structural features of pilot operated safety valve :
1. The soft seal of the valve seat guarantees a good seal before and after the safety valve takes off.
2. Allow the working pressure to approach the setting pressure of the safety valve.
3. A small overpressure can make the main valve of the safety valve reach the fully opened state quickly.
4. The performance and opening height of the safety valve are not affected by back pressure.
5. Adjustable opening and closing pressure difference.
6. The non-flowing structure design of the pilot valve reduces the emission of harmful media and environmental pollution.
7. The setting pressure of the safety valve can be detected online.
一种由主阀和导阀组成的一种新颖结构的安全阀,导阀响应系统介质压力自身动作从而控制主阀的开关动作。 The pilot-operated safety valve is a safety valve of a novel structure composed of a main valve and a pilot valve. The pilot valve acts on its own in response to the pressure of the system medium to control the opening and closing of the main valve.
Pilot operated safety valves are particularly suitable for applications with high back pressure, high flow, high pressure and compact installation locations. Pilot-operated safety valves are mainly used in the fields of petroleum and natural gas, chemical industry, electric power, metallurgy and city gas, etc., and are the best overpressure protection devices on pressure equipment, vessels or pipelines.
先导式安全阀 处于关闭状态时,系统压力通过进口压力管、导阀和气室压力管传到主阀阀瓣顶部的圆顶气室,从而在主阀瓣上产生了一个向下的净作用力,使主阀处于关闭状态。 When the system works normally and the pilot-operated safety valve is closed, the system pressure is transmitted to the dome air chamber on the top of the main valve disc through the inlet pressure pipe, the pilot valve and the air chamber pressure pipe, thereby creating a direction on the main valve disc. Under the net force, the main valve is closed. When the system pressure reaches the set pressure, the pilot valve opens and the shuttle closes the pilot valve intake passage. The pressure in the main valve air chamber is discharged through the pilot valve to relieve the pressure. Because the system pressure is higher than the return pressure, the shuttle closes the intake passage. As a result, the flow of fluid in the pilot valve is blocked. At this time, the pressure of the main valve air chamber drops sharply, the main valve flap is completely opened, and the fluid is released through the main valve to reduce the pressure. When the system pressure drops to a certain value, the spring force of the pilot valve overcomes the force acting on the shuttle by the inlet pressure of the valve, the pilot valve returns to its seat, the ejector pushes the shuttle back, and finally the fluid re-enters the dome gas of the main valve. Chamber, close the main valve.
的主要优点是变弹簧直接作用为导阀间接作用,提高了动作的灵敏度,而且主阀采用套筒活塞式,双重密封阀座结构,动作精度高、重复性好、回座快、不泄漏、能带高背压排放、工作等命长、工作稳定可靠,它还可在线调校,反复启跳排放后,仍然能自动回座,关闭严密,操作维护方便。 The main advantage of the pilot operated safety valve is that the direct action of the spring is changed to the indirect action of the pilot valve, which improves the sensitivity of the action. Moreover, the main valve uses a sleeve piston type and a double-sealed seat structure. , No leakage, high back pressure discharge, long working life, stable and reliable work, it can also be adjusted online, after repeated start-up and discharge, it can still automatically return to the seat, close tightly, convenient operation and maintenance.
