德國洛克進口襯膠截止閥廣東地區(qū)暢銷

進口襯膠截止閥結構特點：

1.襯膠截止閥具有結構緊湊、啟閉靈活、耐腐蝕性能強，行程短（一般為公稱通徑1/4）等項優(yōu)點，被廣泛應用在石油、化工等管路系統(tǒng)中做截斷介質用，但需要強調的是氟塑料襯里的截止閥嚴禁用做流量調節(jié)，以免節(jié)流口處產生的高速介質流沖蝕 破壞密封面。

2.閥瓣與閥桿設計為一體結構，用以防止由于管路壓力波動造成內件沖出閥體的可能性，結構緊湊，使用安全。

Working principle of imported rubber lined stop valve:
Rubber lined valves are mainly steel valves. Rubber materials are covered inside the valve body. The lining materials include butyl rubber, natural rubber, EPDM rubber, chloroprene rubber, nitrile rubber, fluororubber, silicone rubber, hard rubber, soft rubber, etc. the suitable media for rubber lining are hydrocyanic acid and 50% fluorocarbon except for strong oxidants (such as nitric acid, chromic acid, concentrated acid, hydrogen peroxide, etc. and organic solvents) Silicic acid, hydrochloric acid, 30% sulfuric acid, 50% hydrofluoric acid, 85% phosphoric acid, alkali, salt, metal plating solution, sodium hydroxide, potassium hydroxide, neutral brine solution, 10% sodium hypochlorite, wet chlorine, ammonia, most alcohols, organic acids and aldehydes, cement, lime slurry, vegetable oil, elemental gas, ethers, ketones, esters, desalted water, purified water, etc;

 

進口襯膠截止閥產品簡介：

德國洛克《DE LOCKE》進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動；截止閥閥桿開啟或關閉行程相對較短，并具有非常可靠的切斷動作，使得它適合作為介質的切斷或調節(jié)及節(jié)流使用，屬于強制密封式閥門，所以在閥門關閉時，必須向閥瓣施加壓力，以強制密封面不泄漏。從自密封的閥門出現后，截止閥的介質流向就改由閥瓣上方進入閥腔，這時在介質壓力作用下，關閥門的力小，而開閥門的力大，閥桿的直徑可以相應地減少；同時，在介質作用下，這種形式的閥門也較嚴密。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，閥體內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，具有強度高、耐腐蝕性好的特點。

Introduction of imported rubber lined globe valve products:
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.
