產(chǎn)品咨詢：
氮氣安全閥是一種保護用閥，它的啟閉件受外力作用下處于常閉狀態(tài)，當設備或管道內(nèi)的介質(zhì)壓力增高，超過規(guī)定值時自動開啟，通過向系統(tǒng)外排放介質(zhì)來防止管道或設備內(nèi)介質(zhì)壓力超過額定數(shù)值，從而達到保護設備或系統(tǒng)的目的。
一般安裝在壓力容器、受壓管道及連接管道上。在液壓支架上，氮氣安全閥一般用在立柱千斤頂上，當千斤頂內(nèi)壓力超過整定壓力時，安全閥開啟，釋放壓力，保護千斤頂。
1）此氮氣安全閥與普通的彈簧安全閥最大不同之處，是利用填充氮氣代替?zhèn)鹘y(tǒng)的彈簧作用，可克服彈簧的疲勞、斷裂等缺點，使安全閥的靈敏度、壽命大大提高。
2）此氮氣安全閥在第一代側(cè)面充氣氮氣安全閥的基礎上，經(jīng)過改進設計，采用底部充氣方式，充氣更簡便，充氣口密封更可靠，不易發(fā)生漏氣的問題。
3）在沖擊壓力和運動速度變化下不會發(fā)生擠隙，撕裂，爬行和干磨生熱的現(xiàn)象，密封性能可靠。
? Material: stainless steel
? Nominal Pressure: 30-55mpa
? Nominal Flow: 500-1000l /min
? Interfaces: M42×2, M40×1.5, DN20, DN25, DN12

Product Consultation:
Nitrogen with valve relief valve is a kind of protection, the opening and closing pieces under the action of external force in a normally closed state, when the equipment or piping within the medium pressure increase, more than a specified value automatically when open, through a discharge medium system to prevent the pipeline or equipment within the medium pressure more than the rated value, so as to achieve the purpose of the protection device or system.
Generally installed in the pressure vessel, pressure pipe and connection pipe. On the hydraulic support, nitrogen safety valve is generally used on the vertical jack. When the internal pressure of the jack exceeds the setting pressure, the safety valve is opened to release pressure and protect the jack.
1) the biggest difference between this nitrogen safety valve and ordinary spring safety valve is that the filling nitrogen replaces the traditional spring action, which can overcome the spring fatigue, fracture and other shortcomings, and greatly improve the sensitivity and life of the safety valve.
2) this nitrogen safety valve is based on the first generation side gas-filled nitrogen safety valve. After an improved design, it adopts the bottom gas-filled mode, which makes it easier to inflate, more reliable to seal the gas-filled mouth and less prone to air leakage.
3) under the change of impact pressure and movement speed, there will be no squeezing, tearing, crawling and dry grinding to generate heat, and the sealing performance is reliable.
