沈阳郑高阀门有限公司燃气截止阀RJ41NF

一、燃气截止阀RJ41F RJ41N结构特点

RJ41F型结构特点

1、采用弹性PTEE作为动密封自补偿填料，具有自密封性能。
2、大径密封圈或倒密封结构，使别胞封维护安全可靠。
3、设置阀杆防尘圈，保护阀门内部部件不受外部环境侵蚀。
4、阀体为桶形结构，强度高，外形美观。密封副采用防火结构。
5、非强制动密封结构，启闭扭矩小，手轮操作平稳。
1.Adopt elastic FTEE as dynamical saline

seif-cmpensating filling, which possrss

self-sealing performance.
2. Large diameter seal ring or back seal

structure can ansure the safety and

reliability of dynamical sealing.
3. Equipped with dustproof ring of valve

handle in order to protect the interior

parts of valve from erosion of exterior

arvironmart.
4. The valve body adopts barrel stnrcture

and possesses high intensity and beautiful

appeararue. The sealed auxiliary adopts

the fireproof structure.
5. Non-forcible dynamical sealing stnchue

posers small open and close torque. The

handwheel can be smoothly operated.

RJ41N型结构特点

1、该阀专为石油液化气的管路成装置设计.
2、密封副采用尼龙1010对不锈钢，密封可靠。可靠的上密封装置严密保护填料，绝无外漏。
3、采用防火结构，即使软密封材料烧损，金属密封仍能起到作用。
1.The valve is specially designed for the pipeline

or equipment of petroleum and liquefied gas.
2.The sealed auxiliary adopts nylon 1010 stainless

steel. The sealing is reliable. Reliable upper

sealing equipment can strictly protect the filling

and absolutely avoid the leakage.
3.Adopts the fireproof structure.Even if the soft

sealing material is burned,the metal seal still

takes effect.
