丹富斯500X泄壓閥產(chǎn)品概述:
500X泄壓/持壓閥由主閥、導(dǎo)閥、針閥、球閥、微形過濾器和壓力表組成水力控制接管系統(tǒng)。利用水力自動操作,即可以作泄壓閥用又可作持壓閥用。作泄壓閥用時(shí),可維持供水路壓力在設(shè)定的安全值之下;做持壓閥用,可維持主閥上游水壓在設(shè)定值之上,保持主閥上游供水壓力。 丹富斯泄壓/持壓閥,泄壓閥性能,泄壓閥作用
本產(chǎn)品利用水力自動控制,不需要其它裝置和能源,保養(yǎng)簡便,一閥多用。
本產(chǎn)品廣泛應(yīng)用于高層建筑、生活區(qū)等供水管網(wǎng)系統(tǒng)及城市供水工程。
丹富斯泄壓/持壓閥,泄壓閥性能,泄壓閥作用
丹富斯500X泄壓閥工作原理:
1、作泄壓閥:當(dāng)導(dǎo)閥調(diào)整為泄壓狀態(tài)時(shí),水通過針閥、主閥控制室、球閥A、泄壓/持壓導(dǎo)閥、球閥B流向出口,此時(shí)主閥處于開啟狀態(tài)。當(dāng)進(jìn)口壓力超過導(dǎo)閥設(shè)定的安全值時(shí),泄壓導(dǎo)閥會自動開啟,通過球閥C放出部分水,使管路泄壓。當(dāng)壓力恢復(fù)到安全值時(shí),泄壓閥自動關(guān)閉。作泄壓閥時(shí),各球閥常開。
2、作持壓閥:當(dāng)導(dǎo)閥調(diào)整為持壓狀態(tài)時(shí),只要主閥進(jìn)口水壓低于導(dǎo)閥設(shè)定值,導(dǎo)閥即關(guān)閉。主要控制室升壓,主閥關(guān)閉。當(dāng)主閥上游供水壓力超過導(dǎo)閥設(shè)定壓力時(shí),導(dǎo)閥才能打開,控制室的水經(jīng)球閥排至出口,控制室降壓主閥開啟,開始供水,即保持了上游水壓。作持壓閥用時(shí),球閥C常閉或用絲堵?lián)Q下。

Dan fuss, 500 x relief valve products overview:
500 x pressure relief/holding pressure valve consists of the main valve, pilot valve, needle valve, ball valve, micro shape filter and pressure gauge of hydraulic control of system. Use of hydraulic automatic operation, can make the pressure release valve and can be used for holding pressure valve. As a pressure relief valve, it can maintain water supply way pressure under the TVC of set; For holding pressure valve, can maintain the main valve upstream water pressure above the set value, maintain the main valve upstream water supply pressure.
This product use hydraulic automatic control, do not need other devices and energy, maintenance is simple, one valve is multi-purpose.
This product is widely used in high-rise buildings, living quarters and other water supply pipe network system and urban water supply engineering.
Dan fuss, 500 x relief valve working principle:
1, A pressure relief valve: when the pilot valve is adjusted for the pressure state, water through the needle valve, the main valve control room, ball valve, A pressure relief/holding pressure pilot valve, ball valve B of exports, at this time the main valve is fully open. When the inlet pressure exceeds the TVC of pilot valve set, pressure pilot valve will automatically open, channelled through ball valve C section water, make the line pressure. When the pressure recovery to TVC, pressure relief valve automatically shut down. As a pressure relief valve, ball valve normally open.
2, for holding pressure valve: when the pilot valve is adjusted for holding pressure, as long as the main valve import water pressure is lower than the pilot valve set point, pilot valve is closed. The main control room booster, the main valve closed. When the main valve upstream water supply pressure exceeds pilot valve set pressure, pilot valve to open, the control room of water through the ball valve to the export, the control room main reducing valve open, began to water supply, that maintain the upstream water pressure. For holding pressure valve, ball valve normally closed C or substituted a plug.
