進口高壓安全閥德國洛克產(chǎn)品中心

一、進口高壓安全閥技術(shù)參數(shù)：

1、公稱壓力：PN16-PN32Mpa

2、公稱通徑：DN3～DN50

3、適用介質(zhì)：油﹑水﹑氣等多種非腐蝕性或腐蝕性介質(zhì)

4、適用溫度：-20℃～+440℃ -70℃～240℃ ≤540℃ ≤570℃等

5、制造材料：20#﹑1Cr18Ni9Ti﹑304﹑316﹑316L﹑12Cr1Mov等

二、進口高壓安全閥結(jié)構(gòu)優(yōu)點：

1、彈簧微啟式安全閥具有結(jié)構(gòu)簡單、密封性能好、開啟壓力準確、排放能力大、回座壓差小、調(diào)整方便等特點。  

2、噴嘴型閥座：閥座為位伐爾噴嘴型閥座，蒸汽流經(jīng)閥座出口處時達到音速，排放系數(shù)大，閥座密封面堆焊鈷鉻鎢硬質(zhì)合金，耐磨抗沖蝕，壽命長。  

3、熱彈性閥瓣：閥瓣設(shè)計為熱彈性結(jié)構(gòu)，利用其在介質(zhì)壓力下微小的變形，提高密封能力，克服安全閥在介質(zhì)壓力下臨近整定壓力時的前泄現(xiàn)象。閥瓣密封面采用先進的激光淬火技術(shù)，提高了硬度、耐磨性、抗沖抗性。  

4、調(diào)節(jié)螺母：通過調(diào)整調(diào)節(jié)螺母，調(diào)整彈簧壓縮量，使閥門能夠很方便、很迅速地獲得準確的整定壓力。  

5、背壓調(diào)整套：調(diào)整閥瓣背壓的輔助機構(gòu)，通過背壓調(diào)整套調(diào)整，可獲得合適的回座壓差。上調(diào)時，使閥門背壓降低。下調(diào)時，使閥門背壓提高。

三、進口高壓安全閥描述：

德國《DE LOCKE》洛克進口高壓安全閥是一種安全保護用閥，它的啟閉件受外力作用下處于常閉狀態(tài)，當設(shè)備或管道內(nèi)的介質(zhì)壓力升高，超過規(guī)定值時自動開啟，通過向系統(tǒng)外排放介質(zhì)來防止管道或設(shè)備內(nèi)介質(zhì)壓力超過規(guī)定數(shù)值。進口高壓安全閥屬于自動閥類，主要用于鍋爐、壓力容器和管道上，控制壓力不超過規(guī)定值，對人身安全和設(shè)備運行起重要保護作用。

The high pressure safety valve imported from Germany "de Locke" is a kind of valve for safety protection. Its opening and closing parts are normally closed under the action of external force. When the medium pressure in the equipment or pipeline rises and exceeds the specified value, it will automatically open. By discharging medium to the outside of the system, the medium pressure in the pipeline or equipment will be prevented from exceeding the specified value. Imported high-pressure safety valve is an automatic valve, which is mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value and plays an important role in protecting personal safety and equipment operation.
