進(jìn)口鍛鋼法蘭球閥｜進(jìn)口法蘭鍛鋼球閥
德國托普進(jìn)口鍛鋼法蘭球閥產(chǎn)品特點(diǎn)：
1、*的閥座：聚多年球閥制造經(jīng)驗(yàn)而設(shè)計(jì)的閥座，確保閥門密封，磨擦系數(shù)低，操作力矩小、多種閥座材料、適應(yīng)范圍廣。
2、開關(guān)無誤的手柄：采用扁頭閥桿，與手柄的連接不會錯位，從而保證手柄指示的開關(guān)狀態(tài)與閥*辭。
3、鎖緊裝置：為防止閥門開關(guān)誤操作，在閥門全開、全關(guān)位置有鎖定孔，確保閥門處于正確的位置。
4、閥桿防飛結(jié)構(gòu)：閥桿為下裝式，防止受壓飛出，同時可在火災(zāi)后，與閥體形成金屬接觸，確保閥桿密封。
Germany top forged steel flange ball valve product features:
1, advanced valve seat: many years of experience in the manufacture of ball valve seat designed to ensure that the valve seal, friction coefficient is low, operating torque is small, a variety of seat materials, to adapt to a wide range of.
2, the switch is no error of the handle: the use of flat head stem, and the handle will not be connected to the dislocation, so as to ensure that the handle switch state and the valve a speech.
3, locking device: to prevent misuse valve switch, the valve fully open, fully closed position with a lock hole, to ensure that the valve is in the correct position.
4, stem anti fly structure: the stem as download type to prevent pressure flying, while after the fire, the formation of metal in contact with the valve stem seal, ensure.
進(jìn)口鍛鋼法蘭球閥產(chǎn)品概述：
鍛鋼球閥采用中心結(jié)構(gòu)，在關(guān)閉過程中，閥座與球冷酷間的密封比壓能迅速增加，從而確保了密封副的可靠密封。當(dāng)閥門開啟時，閥座與球體能迅速脫離，有效地減小了操作力矩，并使閥座表面與球面之間的控傷可能性降到zui小。
a、(浮動式)采用了彈性加載結(jié)構(gòu)，在正常關(guān)閉情況下確保了球體密封面與閥座密封之間的接觸，在高溫工況下，能有效補(bǔ)償內(nèi)件受熱膨脹，避免因高溫而導(dǎo)致的卡阻，適合于中小口徑高溫使用場合。
b、除金屬硬密封偏心球閥的偏心特點(diǎn)外，其它優(yōu)點(diǎn)在此也具務(wù)，此外，它可雙向使用，且不易在中腔沉積污物，根據(jù)用戶工況條件，也可在中腔設(shè)置排污口。
c、 球體表面采用特殊硬化處理，閥座整體用特種硬質(zhì)材料或局部堆焊硬質(zhì)材料，確保密封副之間的有合適的硬度差。
d、由于球體表面采用特殊的表面硬化處理，閥座采用堆焊硬質(zhì)合金，所以在閥門的啟閉過程中能很好經(jīng)受介質(zhì)沖刷，特別適合于固體顆粒和磨料介質(zhì)。
forged steel ball valve using center structure, in the closing process, the sealing between the valve seat and the ball cold pressure can increase rapidly, so as to ensure reliable sealing sealing. When the valve is opened, the valve seat and the ball can be quickly separated, effectively reducing the operating torque, and to minimize the possibility of damage to the surface between the valve seat and the spherical surface.
A, (floating) using elastic loading structure, under normal circumstances to ensure close the ball and valve seat sealing surface between the sealing contact, in high temperature conditions, can effectively compensate the internal thermal expansion, to avoid jamming caused by high temperature, suitable for small and medium caliber occasions with high temperature.
In addition, the B characteristics of eccentric metal hard seal eccentric ball valve, which also has other advantages. In addition, it can be used in two-way, and not easy in cavity deposition dirt, according to user's working conditions, but also in the cavity to set the sewage outfall.
C, the surface of the ball with special hardening treatment, the valve seat with the use of special hard material or local surfacing hard material, to ensure that the seal between the appropriate hardness difference.
D, due to the surface of the ball using a special surface hardening treatment, the valve seat is welded with hard alloy, so in the process of opening and closing the valve can withstand the media erosion, particularly suitable for solid particles and abrasive media.
