進(jìn)口可調(diào)式水用減壓閥(德國OLES奧萊斯閥門)
【進(jìn)口可調(diào)式水用減壓閥】詳細(xì)說明:
水用減壓閥是采用控制閥體內(nèi)的啟閉件的開度來調(diào)節(jié)介質(zhì)的流量,將介質(zhì)的壓力降低。水用減壓閥同時借助閥后壓力的作用調(diào)節(jié)啟閉件的開度,使閥后壓力保持在一定范圍內(nèi),在進(jìn)口壓力不斷變化的情況下,自來水減壓閥保持出口壓力在設(shè)定的范圍內(nèi),保護(hù)其后的生活生產(chǎn)器具。采用了全通道流線型設(shè)計,流本阻力小,流量大。在傳動方式上采用了水力操作,即利用管路中的水壓自動操作主閥盤的下下移動,控制閥門開度,調(diào)節(jié)下游壓力,使下游壓力維持在導(dǎo)閥彈簧設(shè)定的壓力值上。當(dāng)下游壓力超過設(shè)定值時,水用減壓閥將自動關(guān)閉,不管入口壓力怎樣波動,都可輸出穩(wěn)定的出口壓力,不管下游流量怎樣變化,都能維持出口壓力穩(wěn)定在導(dǎo)閥設(shè)定值上。同時通過導(dǎo)閥調(diào)節(jié)的出口壓力,調(diào)節(jié)范圍大,可達(dá)閥前壓力10-80%,且工作平穩(wěn),無水錘沖擊現(xiàn)象。
The water pressure relief valve uses the opening of the opening and closing parts in the control valve body to regulate the flow rate of the medium and reduce the pressure of the medium. At the same time, the opening of the opening and closing parts of the water pressure relief valve is regulated by the function of the back pressure of the valve, so that the back pressure of the valve can be kept within a certain range. In the case of constant changes in the import pressure, the tap water pressure relief valve keeps the outlet pressure within a set range and protects the subsequent life and production equipment. The whole channel streamlined design is adopted, with small flow resistance and large flow rate. Hydraulic operation is adopted in the transmission mode, that is, the water pressure in the pipeline is used to automatically operate the lower movement of the main valve disc, control the opening of the valve and regulate the downstream pressure, so that the downstream pressure is maintained at the pressure value set by the guide valve spring. When the downstream pressure exceeds the set value, the water pressure relief valve will automatically close. No matter how the inlet pressure fluctuates, the stable outlet pressure can be output. No matter how the downstream flow changes, the outlet pressure can be maintained at the set value of the pilot valve. At the same time, the outlet pressure regulated by the guide valve can reach 10-80% of the pre-valve pressure, and work smoothly without water hammer impact.
【進(jìn)口可調(diào)式水用減壓閥】工作原理:
減壓閥的工作原理建立在兩基本點(diǎn)壓力平衡的基礎(chǔ)上:
1.彈簧向下施加的開啟活塞力量。
2.膜片向上的作用的關(guān)閉活塞的力量。
【進(jìn)口可調(diào)式水用減壓閥】特點(diǎn):
水用減壓閥為內(nèi)螺紋連接,由閥體、閥蓋、壓縮彈簧、閥桿及膜片等組成,采用閥后壓力直接傳遞作用于膜片下方并與膜片上方壓力保持*平衡狀態(tài)的結(jié)構(gòu)。水用減壓閥具有動作靈敏、快捷、性能可靠、使用壽命長、形體小巧、易于安裝等特點(diǎn)、使其更加安全可靠。
1.自來水用減壓閥采用直接作用隔膜式結(jié)構(gòu),內(nèi)部結(jié)構(gòu)非常簡單,無卡阻,性能可靠,經(jīng)久耐用。
2、絲扣減壓閥耐臟防水垢,不需過濾器,不需旁通管,配管極其簡單,能節(jié)省大量空間和配管成本。
3、減壓閥出口壓力精密可調(diào)。
4、本減壓閥大水力特性,壓力損失小,流量損失小,閥后壓力0.5-6公斤可調(diào)節(jié),大耐壓16公斤。
5、可滿足多種減壓要求,特別適用于支路減壓閥系統(tǒng)。
安裝調(diào)節(jié):
1.水用減壓閥主閥的*安裝方式是水平臥式安裝,其他安裝方式也可達(dá)到操作功能。減壓閥安裝前要*清除管道內(nèi)的雜物,要注意主閥體外水流標(biāo)標(biāo)箭頭,遵循方向安裝,安裝后應(yīng)確保沒有管路應(yīng)力作用在閥體 及閥內(nèi)部件上。
2.主閥前要安裝一只閘閥和一只過濾器,主閥后也要裝一只閘閥,以便于維修。
3.水用減壓閥導(dǎo)閥與導(dǎo)管控制系統(tǒng)已于出廠前裝配和調(diào)整完畢,如導(dǎo)閥出廠設(shè)定壓力值不適合現(xiàn)場要求,可通過擰緊或放松導(dǎo)閥上端螺釘來調(diào)節(jié),順時針擰動螺釘為增加壓力,逆時針擰動螺釘為減少壓力,調(diào)節(jié)完 后擰緊鎖緊螺母。
4.主閥上的微型過濾器要定期清洗。
5.通水前的須*沖洗管路系統(tǒng)。
6.對重要給水管路應(yīng)安裝旁通閥
