【进口高温止回阀】详细说明:

高温高压止回阀整体采用锻造工艺，是高温、高压管路中防止介质倒流，如火电厂、核电站，石油化工系统的高温、高压管路上。按锻钢高温高压止回阀可按以下三个工艺：

1、螺栓式阀盖，按这种设计形式设计的阀门，其阀体与阀盖用螺栓螺母连接，缠绕式垫片（316夹柔性石墨制造）密封。客户有特殊要求时也可采用金属环连接。

2、焊接式阀盖，按这种设计形式的阀门，其阀体与阀盖用螺纹连接，全焊密封。客户有特殊要求时也可采用全焊透连接。

3、压力自紧式阀盖，按这种设计形式设计的阀门，其阀体与阀盖用螺纹连接，内压自密环密封。

High temperature and high pressure check valves are forged to prevent medium backflow in high temperature and high pressure pipelines, such as thermal power plants, nuclear power plants and high temperature and high pressure pipelines in petrochemical systems. According to forged steel high temperature and high pressure check valve, the following three processes can be adopted:

1. Bolted bonnet. Valves designed according to this design form are connected with the bonnet by bolts and nuts, and sealed by winding gaskets (316 clips of flexible graphite). Metal rings can also be used when customers have special requirements.

2. Welded bonnet. According to this design, the body of the valve is threaded to the bonnet, and the valve is fully welded and sealed. Full penetration can also be used when customers have special requirements.

3. Pressure self-tightening valve cover. The valve designed according to this design form has a threaded connection between the body and the cover, and an internal pressure self-tightening ring is sealed.

【进口高温止回阀】特点：

1.阀门中腔采用压力自紧式密封结构，内腔压力越高密封性能越好。

2.支管两端为对焊连接，适应不同的接管要求。

3.阀门耐压部件选用优质耐热合金钢制造，高温性能好，承受压力高，耐用、安全、可靠。

4.阀瓣、阀座的密封面采用司太立（stellite）钴基硬质合金堆焊而成，耐磨、耐高温，抗擦伤性能好、使用寿命长。

5.阀瓣围绕阀座外的销轴旋转，减少关闭时发生猛烈冲击。

6.内装式的销轴结构，减小外泄漏点，使用更可靠。

【进口高温止回阀】特性：

阀瓣上部和阀盖下部加工有导向套简，阀瓣导向简可在阀盏导向简内自由升降，当介质顺流时，阀瓣靠介质推力开启，当介质停流时，阀瓣靠自垂降落在阀座上，起阻止介质逆流作用
