RJ41N-16C、25、 40型液化氣截止閥RJ41N

一、RJ41N-16C、RJ41N-25、RJ41N-40型液化氣截止閥結(jié)構(gòu)以及使用

1、采用彈性PTEE作為動密封自補(bǔ)償填料，具有自密封性能。
2、大徑密封圈或倒密封結(jié)構(gòu)，使別胞封維護(hù)安全可靠。
3、設(shè)置閥桿防塵圈，保護(hù)閥門內(nèi)部部件不受外部環(huán)境侵蝕。
4、閥體為桶形結(jié)構(gòu)，強(qiáng)度高，外形美觀。密封副采用防火結(jié)構(gòu)。
5、非強(qiáng)制動密封結(jié)構(gòu)，啟閉扭矩小，手輪操作平穩(wěn)。
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.

1、該閥專為石油液化氣的管路成裝置設(shè)計(jì).
2、密封副采用尼龍1010對不銹鋼，密封可靠�？煽康纳厦芊庋b置嚴(yán)密保護(hù)填料，絕無外漏。
3、采用防火結(jié)構(gòu)，即使軟密封材料燒損，金屬密封仍能起到作用。
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.
