二、進(jìn)口LNG液化天然氣安全閥產(chǎn)品簡(jiǎn)介：

德國(guó)洛克進(jìn)口低溫LNG液化天然氣安全閥是指用于低溫LNG液化天然氣系統(tǒng)上，啟閉件受外力作用下處于常閉狀態(tài)，當(dāng)?shù)蜏卦O(shè)備或管道內(nèi)的低溫LNG液化天然氣介質(zhì)壓力升高超過規(guī)定值時(shí)，通過向系統(tǒng)外排放LNG液化天然氣來防止低溫管道或設(shè)備內(nèi)介質(zhì)壓力超過規(guī)定數(shù)值的閥門?？刂频蜏?/font>LNG液化天然氣不超過規(guī)定值，對(duì)人身安全和設(shè)備運(yùn)行起重要保護(hù)作用。

The low temperature LNG LNG LNG safety valve imported from Germany is used in the cryogenic LNG LNG system. The opening and closing parts are normally closed under the action of external force. When the medium pressure of low-temperature LNG LNG in low-temperature equipment or pipeline increases more than the specified value, LNG liquefied natural gas is discharged out of the system to prevent the medium pressure in the low-temperature pipeline or equipment from exceeding the specified value Valves. It plays an important role in personal safety and equipment operation to control the low temperature LNG liquefied natural gas not exceeding the specified value.

三、進(jìn)口LNG液化天然氣安全閥結(jié)構(gòu)特點(diǎn)：

1、低溫安全閥經(jīng)過低溫深冷處理，能耐-196℃低溫

2、低溫安全閥閥瓣材料經(jīng)過鍍鉻或氮化處理，提高閥桿表面硬度，提高填料密封的可靠性。

3、低溫安全閥用的墊片具有在常溫下、低溫狀態(tài)及溫度變化下能可靠密封性和復(fù)原性。

4、低溫安全閥采用優(yōu)質(zhì)的德國(guó)洛克彈簧材料，起跳排放精確安全。

5、啟動(dòng)自如、密封可靠、起跳壓力穩(wěn)定等

6、開啟高度≥1/4喉部直徑，排放量大；

7、帶扳手的安全閥，當(dāng)介質(zhì)壓力達(dá)到開啟壓力的75%以上時(shí)，能利用扳手手動(dòng)開啟；

8、有螺紋，法蘭，焊接，多種連接方式，帶焊接管可拆卸安裝維修方便。

1. After cryogenic treatment, the low temperature safety valve can withstand - 196 ℃

2. After chromium plating or nitriding treatment, the surface hardness of valve stem and the reliability of packing seal are improved.

3. The gasket for low temperature safety valve has reliable sealing and recovery under normal temperature, low temperature state and temperature change.

4. The low temperature safety valve is made of high-quality German rock spring material, which is precise and safe for taking off and discharging.

5. It is easy to start, reliable in sealing and stable in take-off pressure

6. When the opening height is more than 1 / 4 of throat diameter, the discharge is large;

7. When the medium pressure reaches 75% of the opening pressure, the safety valve with wrench can be opened manually;

8. There are thread, flange, welding, a variety of connection, with welded pipe can be disassembled, installed and maintained conveniently.
