進口燃氣安全閥產(chǎn)品簡介-德國洛克

一、進口燃氣安全閥技術(shù)參數(shù)：

1、公稱通徑：DN15-DN400

2、公稱壓力：PN1.0MPa-PN32MPa

3、連接方式：法蘭、焊接、絲扣

4、閥體材料：碳鋼、不銹鋼、黃銅

5、閥    芯：不銹鋼、黃銅

6、適用介質(zhì)：天然氣、液化石油氣等。

7、適用溫度：≤180℃

二、進口燃氣安全閥結(jié)構(gòu)特點：

1、全啟式結(jié)構(gòu)，排量大

2、全封閉結(jié)構(gòu)，有效防止介質(zhì)外漏

3、平面結(jié)構(gòu)的閥瓣和閥座易于維修和重新加工

4、整定壓力偏差小，可達±3%

5、選用優(yōu)質(zhì)的彈簧鋼，保證彈簧的壽命和穩(wěn)定性

6、四氟軟密封結(jié)構(gòu)，密封可靠耐用

三、進口燃氣安全閥描述：

德國《DE LOCKE》洛克進口燃氣安全閥（Steam Safty Valve），也稱燃氣泄壓閥，它是指用在燃氣系統(tǒng)管道中，當燃氣系統(tǒng)壓力超過規(guī)定值時，閥門打開，將燃氣系統(tǒng)中的一部分蒸汽出，使燃氣系統(tǒng)壓力不超過允許值，從而保證燃氣系統(tǒng)不因壓力過高而發(fā)生事故的安全裝置。進口安全閥燃氣管道一般用封閉帶扳手全啟式安全閥，安全閥有彈簧式和桿式兩大類。另外還有沖量式安全閥、先導式安全閥、安全切換閥、安全解壓閥、靜重式安全閥等。彈簧式安全閥主要依靠彈簧的作用力而工作，彈簧式安全閥中又有封閉和不封閉的，一般易燃、易爆或有毒的介質(zhì)應(yīng)選用封閉式，蒸汽或惰性氣體等可以選用不封閉式，在彈簧式安全閥中還有帶扳手和不帶扳手的。扳手的作用主要是檢查閥瓣的靈活程度，有時也可以用作手動緊急泄壓用。

Description of imported gas safety valve:
German "de lock" imported gas safety valve Valve), also known as gas pressure relief valve, refers to the safety device used in the gas system pipeline. When the gas system pressure exceeds the specified value, the valve will open, and part of the steam in the gas system will be discharged, so that the gas system pressure does not exceed the allowable value, so as to ensure that the gas system will not have accidents due to high pressure. Imported safety valve gas pipeline is generally closed with wrench full open safety valve, safety valve has spring type and rod type two categories. In addition, there are impulse type safety valve, pilot type safety valve, safety switching valve, safety decompression valve, static weight type safety valve, etc. Spring type safety valve mainly depends on the force of spring, and there are closed and unclosed in spring type safety valve. Generally, flammable, explosive or toxic medium should be closed, steam or inert gas can be unclosed, and there are wrench and no wrench in spring type safety valve. The wrench is mainly used to check the flexibility of the valve disc, sometimes it can also be used for manual emergency relief.
