设计规范：

设计制造：ASME B16.34

结构长度：ASME B16.10

连接尺寸：ASME B16.25

压力-温度： ASME B16.34

试验-检验：  API 598

氦质谱检漏：API 602 MSS SP-117

应用：适用于超高温熔盐介质。

设计特点：

1：多层密封设计，确保零泄漏：

第一道密封：波纹管组件密封，采用内藏式设计，免冲刷结构，保证使用寿命。

第二道密封：采用超高温专用低泄露填料（蛭石），完全不受氧化作用影响，更增加了可靠性、安全性以及耐高温性。

2：阀体阀盖螺纹连接+焊接，强度密封双重保证。

3：波纹管选用特材英科镍625

4：中法兰采用凹槽设计，缠绕垫片完全定位，防止垫片挤出损坏。

5：密封面特性：一体式阀座，线密封，整体堆焊硬质合金，

锥形阀座，切除结晶熔盐。

Application: For ultra-high temperature molten salt media.
Design features：
1: Multi-layer seal design to ensure zero leakage:.

First seal: bellows assembly seal with built-in design and flush-free construction that guarantee the service life.

The second seal: the use of ultra-high temperature special low leakage filler (vermiculite), completely unaffected by oxidation.

This increases reliability, safety and high temperature resistance.

2: Threaded connection of the valve body and cover + welding,

double guarantee of strength and sealing.
3: The bellows is made of special material Inconel 625
4: The middle flange is grooved and the winding gasket is fully

positioned to prevent gasket extrusion damage.
5: Sealing surface characteristics: one-piece valve seat, line sealing,

overall overlay carbide. Conical sealing, removal of crystalline molten salt.
