進(jìn)口德標(biāo)止回閥,(德國OLES閥門品牌)
【進(jìn)口德標(biāo)止回閥】詳細(xì)說明：
止回閥是指依靠介質(zhì)本身流動(dòng)而自動(dòng)開、閉閥瓣，用來防止介質(zhì)倒流的閥門，又稱逆止閥、單向閥、逆流閥和背壓閥。止回閥屬于一種自動(dòng)閥門，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動(dòng)電動(dòng)機(jī)反轉(zhuǎn)，以及容器介質(zhì)的泄放。止回閥還可用于給其中的壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)提供補(bǔ)給的管路上。止回閥主要可分為旋啟式止回閥（依重心旋轉(zhuǎn)）與升降式止回閥（沿軸線移動(dòng)）。
止回閥這種類型的閥門的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止反方向流動(dòng)。通常這種閥門是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開；流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。
可廣泛用于自來水、污水、建筑、石油、化工、食品、醫(yī)藥、輕紡、電力、船舶、冶金、能源系統(tǒng)等體管線上。
Check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent medium backflow, also known as check valve, one-way valve, counterflow valve and back pressure valve. Check valve is an automatic valve. Its main function is to prevent medium backflow, reverse pump and drive motor, and release of container medium. Check valves can also be used in pipelines to supply auxiliary systems where pressure may rise above system pressure. Check valves can be divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
Check valves of this type are designed to allow media to flow in only one direction and prevent reverse flow. Usually, the valve operates automatically, and the disc opens under the action of a fluid pressure flowing in one direction. When the fluid flows in the opposite direction, the disc acts on the seat by the fluid pressure and the self-coincidence disc of the disc, thus cutting off the flow.
It can be widely used in water, sewage, construction, petroleum, chemical industry, food, medicine, textile, power, ship, metallurgy, energy system and other body pipelines.
