進(jìn)口底閥,(德國OLES奧萊斯閥門)
【進(jìn)口底閥】詳細(xì)說明：
底閥是一種節(jié)約能源的閥,一般安裝在水泵水下吸管的底端.限制水泵管內(nèi)液體返回水源,起著只進(jìn)不出的功能.閥蓋上有很多個(gè)進(jìn)水品和加強(qiáng)筋,起到了不易堵塞,主要應(yīng)用在抽水的管路上.水道和支承的作用.口徑有單瓣,雙瓣,多瓣型.有法蘭連接和螺紋連接該產(chǎn)品重量輕,安裝方便,連接方式有:法蘭式、承插焊接式、螺紋式,產(chǎn)品結(jié)構(gòu)形式有:浮球式,自動(dòng)翻板大流量式,可與各種離心泵,自吸泵,配套使用.該產(chǎn)品結(jié)構(gòu)新穎,密封性能*.能耐酸.耐堿,耐腐蝕.使用時(shí)間長.廣泛應(yīng)用于化工,化纖、氯堿、電力,制藥,農(nóng)藥,染料,冶煉,食品、污水處理,海水養(yǎng)殖,等行業(yè).
Bottom valve is a kind of energy-saving valve, which is usually installed at the bottom of the underwater suction pipe of the pump. Limiting the return of liquid to the water source in the pump pipe, it has the function of only entering and not entering. There are many water intake products and reinforcing bars on the valve cover, which are not easy to block and are mainly used in the pumping pipeline. The water channel and supporting function. The caliber has single, double and multi-lobe type. Flanged connection and threaded connection are light in weight, easy to install, connection modes are flange type, socket welding type, threaded type, product structure forms are: floating ball type, automatic turning plate type, large flow type, can be used with various centrifugal pumps, self-priming pumps, supporting. The product has novel structure, excellent sealing performance, acid resistance, alkali resistance, corrosion resistance. Intermediate length. Widely used in chemical industry, chemical fiber, chlor-alkali, electric power, pharmaceuticals, pesticides, dyes, smelting, food, sewage treatment, mariculture, and other industries.
【進(jìn)口底閥】特點(diǎn)：
1、水上式底閥是替代水下式底閥、安裝于水面以上水平管與進(jìn)水管的90°轉(zhuǎn)彎處，亦可代替彎頭，其密封性能*，達(dá)到滴水不漏，并設(shè)有阻尼裝置，對水錘危害有一定的減緩作用。
2、為了防止介質(zhì)逆流，在設(shè)備、裝置和管道上都應(yīng)安裝止回閥；
3、止回閥一般適用于清凈介質(zhì)，不宜用于含有固體顆粒和粘度較大的介質(zhì)；
4、一般在公稱通經(jīng)50mm的水平管道上都應(yīng)選用立式升降止回閥。
【進(jìn)口底閥】用途：
底閥是一種節(jié)約能源的閥,一般安裝在水泵水下吸管的底端.限制水泵管內(nèi)液體返回水源,起著只進(jìn)不出的功能.閥蓋上有很多個(gè)進(jìn)水品和加強(qiáng)筋,起到了不易堵塞,主要應(yīng)用在抽水的管路上.水道和支承的作用.口徑有單瓣,雙瓣,多瓣型.有法蘭連接和螺紋連接。
結(jié)構(gòu)原理：
底閥由閥估,閥瓣,閥蓋,襯套,密封圈等零件組成,詳見下圖水源的水從閥蓋進(jìn)入閥體.在流體的壓力作用下,閥瓣打開水,當(dāng)示停后出口管內(nèi)的壓力將閥瓣迅速關(guān)閉,液體將不會(huì)倒回水源,起到了即暢通抽水又節(jié)約水能損失的作用。
