丹富斯200X減壓閥是一種利用介質(zhì)自身能量調(diào)節(jié)與控制管路壓力的職能型閥門。    200X減壓閥用于生活給水、消防 給水及其他工業(yè)給水系統(tǒng)，通過調(diào)節(jié)減壓導(dǎo)閥，即可調(diào)節(jié)主閥的出口壓力。出口壓力不因進(jìn)口壓力、進(jìn)口流量的 變化而變化，安全可靠地將出口壓力維持在設(shè)定值上，并可根據(jù)需要調(diào)節(jié)設(shè)定值以達(dá)到減壓目的。該閥減壓精確， 性能穩(wěn)定、安全可靠、安裝方便，使用壽命長(zhǎng)。 　　丹富斯減壓閥、可調(diào)式減壓閥、減壓閥規(guī)格。

Dan fuss, 200 x pressure reducing valve is a kind of USES the energy of medium type and the function of control line pressure valve adjustment. 200 x pressure reducing valve used in the drinking water, fire water, and other industrial water supply system, by adjusting the pressure pilot valve, can adjust the outlet pressure of the main valve. Outlet pressure does not change due to the change of inlet pressure, inlet flow, safe and reliable to keep outlet pressure on the set value, and can according to need to adjust the Settings to achieve the relief. The valve decompression precision, stable performance, safe and reliable, easy installation, long service life.  

丹富斯200X減壓閥結(jié)構(gòu)特點(diǎn)和用途： 　　丹富斯減壓閥、可調(diào)式減壓閥、減壓閥規(guī)格。

            200X減壓閥由主閥、導(dǎo)閥、針閥、球閥、微型過濾器和壓力表組成水力控制接管系統(tǒng)。使用時(shí)，當(dāng)調(diào)定出口壓力后，能自動(dòng)保持穩(wěn)定出口壓力。本產(chǎn)品利用導(dǎo)閥自力控制，不需要其它裝置和能源，保養(yǎng)簡(jiǎn)便，壓力控制準(zhǔn)確度高，受進(jìn)口壓力和流量影響小，減壓穩(wěn)壓可靠。200X減壓閥廣泛用于高層建筑、生活區(qū)等供水管網(wǎng)系統(tǒng)及城市供水工程。 　

Dan fuss, 200 x pressure reducing valve structure features and use: 
 
200 x pressure reducing valve consists of the main valve and pilot valve, needle valve, ball valve, micro filter and pressure gauge of hydraulic control of system. After use, when the setting outlet pressure, stable outlet pressure automatically. This product use pilot valve to control themselves, do not need other devices and energy sources, convenient maintenance, pressure control accuracy is high, affected by the inlet pressure and flow rate is small, reduced pressure regulator is reliable. 200 x pressure reducing valve is widely used in water supply network system of high-rise buildings, residential and urban water supply engineering. 　

丹富斯200X減壓閥工作原理： 　　

        當(dāng)閥門從進(jìn)口端給水時(shí)，水流過針閥進(jìn)入主閥控制室，出口壓力通過導(dǎo)管作用到導(dǎo)閥上。當(dāng)出口壓力高于導(dǎo)閥彈簧設(shè)定值時(shí)，導(dǎo)閥關(guān)閉?？刂剖彝Ｖ古潘?，此時(shí)主閥控制室內(nèi)壓力升高并關(guān)閉主閥，出口壓力不再升高。當(dāng)閥門出口壓力降到導(dǎo)閥彈簧設(shè)定壓力時(shí)，導(dǎo)閥開啟，控制室向下游排水。由于導(dǎo)閥系統(tǒng)排水量大于針閥的進(jìn)水量，主閥控制室壓力下降。進(jìn)口壓力使主閥開啟。在穩(wěn)定狀態(tài)下，控制室進(jìn)水、排水相同，主閥開度不變，出口壓力穩(wěn)定。

Dan fuss, 200 x pressure reducing valve working principle: 
 
When the valve from the inlet water supply, water flows through a needle into the main valve control room, outlet pressure through the catheter to the pilot valve. When the outlet pressure is higher than the pilot valve spring set value, pilot valve to close. Control room to stop drainage, at this time the main valve to control the indoor pressure and close the main valve, outlet pressure is no longer increases. When the valve outlet pressure down to guide valve spring set pressure, the pilot valve open, the control room to the downstream drainage. Because the pilot valve system of displacement is greater than the needle valve into the water, the main valve control room pressure drop. Open the main valve inlet pressure. Under steady state, the control room the same feed water and drainage, the main valve opening is changeless, outlet pressure stability.
