進口彈簧式安全閥德國洛克物美價廉值得信賴

一、進口彈簧式安全閥技術(shù)參數(shù)：

1、連接方式有:法蘭連接、焊接連接、絲扣、螺紋

2、閥門工作壓力從0.1MPA-64MPA、

3、閥門口徑：DN2~DN600。

4、閥門工作溫度為-20度至500度。

5、材質(zhì)有:鑄鋼、不銹鋼、鉻鉬鋼、鉻鉬釩鋼、雙相不銹鋼、黃銅等

二、進口彈簧式安全閥分類：

結(jié)構(gòu)形式：垂錘式、杠桿式、彈簧式和先導(dǎo)式(脈沖式)；閥體構(gòu)造：封閉式和不封閉式兩種。封閉式安全閥即排除的介質(zhì)不外泄，全部沿著出口排泄到指定地點，一般用在有毒和腐蝕性介質(zhì)中。對于空氣和蒸汽用安全閥，多采用不封閉式安全閥。對于安全閥產(chǎn)品的選用，應(yīng)按實際密封壓力來確定。對于彈簧式安全閥，在一種公稱壓力(PN)范圍內(nèi)，具有幾種工作壓力級的彈簧。

三、進口彈簧式安全閥描述：

德國《DE LOCKE》洛克進口彈簧式安全閥指依靠彈簧的彈性壓力而將閥的瓣膜或柱塞等密封件閉鎖，一旦當(dāng)壓力容器的壓力異常后產(chǎn)生的高壓將克服安全閥的彈簧壓力，所以閉鎖裝置被頂開，形成了一個泄壓通道，將高壓泄放掉。根據(jù)閥瓣開啟高度不同又分為全起式和微起式兩種。全起式泄放量大，回彈力好，適用于液體和氣體介質(zhì)，微起式只宜用于液體介質(zhì)。

The spring type safety valve imported from Germany "de Locke" means that the valve or plunger and other seals of the valve are locked by the elastic pressure of the spring. Once the pressure of the pressure vessel is abnormal, the high pressure generated will overcome the spring pressure of the safety valve, so the locking device is pushed open to form a pressure relief channel to release the high pressure. According to the disc opening height, it can be divided into full lift and micro lift. The full lift type has large discharge capacity and good resilience, and is suitable for liquid and gas medium, while the micro lift type is only suitable for liquid medium.
