進口波紋管減壓閥產(chǎn)品特點-德國洛克

進口波紋管減壓閥安裝說明： 

①為了操作和維護方便，該波紋管減壓閥一般直立安裝在水平管道上，橫向安裝須特別說明。

②安裝時應(yīng)注意使管路中介質(zhì)的流向與波紋管減壓閥體上所示箭頭的方向一致。

③為了防止波紋管減壓閥后壓力超壓，應(yīng)在離閥出口不少于4M處安裝一個安全閥。

進口波紋管減壓閥工作原理：

1,閥前進口介質(zhì)壓力從閥瓣和閥體密封圈開啟間隙進入體腔使介質(zhì)壓力流滿波紋管的組合箱，波紋管和彈簧因受介質(zhì)壓力的擠壓而壓縮，閥瓣隨著閥桿位移，閥瓣產(chǎn)生對閥體密封圈的關(guān)閉，將閥前介質(zhì)截止，不作閥后介質(zhì)壓力的補充。當(dāng)閥后的介質(zhì)壓力降低，波紋管因受調(diào)節(jié)彈簧的徑項力，使波紋管疊紋變形，閥桿將閥瓣頂開。使介質(zhì)通過閥體密封圈補充閥后壓力的降低。

2,本閥是由閥體、閥蓋、閥瓣、閥體密封圈、閥桿、波紋管、調(diào)節(jié)彈簧等零件組成，體腔進口組裝有閥瓣、閥體密封圈和輔彈簧，輔彈簧是保持閥瓣和閥體密封圈自動的密封，出口體腔組裝彈性密封元件（波紋管）即保證閥后介質(zhì)壓力的泄漏和克服壓力不均勻度的補償。螺釘是調(diào)整彈簧負(fù)荷壓力減壓閥工作性能。

進口波紋管減壓閥產(chǎn)品簡介：

進口波紋管減壓閥屬于直接作用式波紋管彈簧減壓閥。主要由波紋管、調(diào)節(jié)彈簧、閥座、閥瓣等零件組成，利用波紋管傳感閥門下游壓力驅(qū)動閥瓣，改變和控制閥門開度實現(xiàn)減壓穩(wěn)壓功能。通過調(diào)節(jié)調(diào)節(jié)螺栓設(shè)定出口壓力。

本產(chǎn)品調(diào)壓、穩(wěn)壓動作靈敏平衡，適用于氣體和液體介質(zhì)的管路使用。

Brief introduction of imported bellows pressure reducing valve:
Imported bellows pressure reducing valve belongs to direct acting bellows spring pressure reducing valve. It is mainly composed of bellows, adjusting spring, valve seat, valve disc and other parts. The bellows is used to sense the downstream pressure of the valve and drive the valve disc to change and control the valve opening to realize the function of pressure reduction and stabilization. Set the outlet pressure by adjusting the adjusting bolt.
This product has sensitive and balanced action of pressure regulation and stabilization, and is suitable for pipeline use of gas and liquid medium.
