進(jìn)口襯膠截止閥工作原理：

襯膠閥門主要是鋼制閥門在閥體內(nèi)部覆有橡膠材料，襯里材料有襯丁基膠、襯天然膠、襯三元乙丙膠、襯氯丁膠、襯丁腈膠、襯F橡膠、襯硅橡膠、硬橡膠、軟橡膠等，襯膠適用介質(zhì)：除強(qiáng)氧hua劑(如硝酸、鉻酸、濃流酸及過氧hua氫等和有機(jī)溶劑)外的氫氰suan、50%F硅酸、鹽酸、30%硫酸、50%氫F酸、85%磷酸、堿、鹽類、鍍金屬溶液、氫氧hua納、氫氧hua鉀、中性鹽水溶液、10%次氯suan鈉、濕lv氣、氨水、大部分醇類、有機(jī)酸及醛類、水泥、石灰漿、植物油、元素氣體、醚類、酮類、酯類、除鹽水、凈hua水等介質(zhì)；

進(jìn)口襯膠截止閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進(jìn)口襯膠截止閥啟閉件是塞形的閥瓣，密封上面呈平面或錐面，閥瓣沿閥座的中心線作直線運(yùn)動；截止閥閥桿開啟或關(guān)閉行程相對較短，并具有非?？煽康那袛鄤幼?，使得它適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用，屬于強(qiáng)制密封式閥門，所以在閥門關(guān)閉時，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。從自密封的閥門出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔，這時在介質(zhì)壓力作用下，關(guān)閥門的力小，而開閥門的力大，閥桿的直徑可以相應(yīng)地減少；同時，在介質(zhì)作用下，這種形式的閥門也較嚴(yán)密。主要分為直通式、直流式和直角式的三種。襯膠截止閥用于控制一般腐蝕性介質(zhì)，閥體內(nèi)腔表面覆有可供選擇的各種橡膠，適用于不同工作溫度和流體管中，具有強(qiáng)度高、耐腐蝕性好的特點(diǎn)。

German Locke's de The opening and closing part of the imported rubber lined stop valve is a plug-in disc, with a flat or conical surface on the sealing surface, and the disc moves in a straight line along the center line of the valve seat. The opening or closing stroke of the stop valve stem is relatively short, and it has a very reliable cut-off action, which makes it suitable for cutting off or regulating as medium and throttling. It is a forced sealing valve, so when the valve is closed, Pressure must be applied to the disc to force the sealing surface against leakage. After the appearance of self sealing valve, the medium flow direction of the stop valve will change from the top of the valve disc to the valve chamber. Under the action of medium pressure, the force to close the valve is small, while the force to open the valve is large, and the diameter of the valve stem can be reduced correspondingly. At the same time, under the action of medium, this type of valve is also more tight. It is mainly divided into straight through type, direct current type and right angle type. Rubber lined globe valve is used to control general corrosive medium. The surface of the inner cavity of the valve body is covered with various kinds of rubber, which is suitable for different working temperatures and fluid pipes. It has the characteristics of high strength and good corrosion resistance.
