德國洛克供應(yīng)優(yōu)質(zhì)進(jìn)口雙向壓蝶閥

一、進(jìn)口雙向壓蝶閥產(chǎn)品簡介：

德國《LOCKE》洛克進(jìn)口雙向壓蝶閥(Dual pressure valve)構(gòu)造合理，密封緊密牢靠、流阻小、壓差低、驅(qū)動(dòng)靈敏省力，運(yùn)用壽命倍增。雙公平，即軸向公平，閥軸中心線不在閥板密封面上；徑向公平：閥軸中心線不在閥門通道的中心線上，閥板采用雙平板桁架式多流道構(gòu)造，在流速較高時(shí)，各流道水流可以相互制衡，防止閥板呈現(xiàn)哆嗦景象，確保閥門的穩(wěn)定性。特殊的設(shè)計(jì)，特殊的幾何構(gòu)造，使閥板具有越關(guān)越緊的功用，當(dāng)翻開閥門時(shí)，只需閥軸略微旋轉(zhuǎn)，閥板即全部脫離閥座，增加了摩擦力，使開啟力矩出現(xiàn)最小最佳形態(tài)，密封嚴(yán)實(shí)牢靠，經(jīng)久耐用。

The dual pressure valve imported from Locke, Germany, has reasonable structure, tight and reliable seal, small flow resistance, low pressure difference, sensitive and labor-saving driving, and double service life. Double fairness, i.e. axial fairness, the center line of the valve shaft is not on the sealing surface of the valve plate; radial fairness: the center line of the valve shaft is not on the center line of the valve channel, and the valve plate adopts the double plate truss type multi channel structure. When the flow velocity is high, the flow in each channel can check and balance each other, so as to prevent the valve plate from shivering and ensure the stability of the valve. The special design and special geometry structure make the valve plate have the function of closing and tightening. When the valve is opened, only the valve shaft rotates slightly, and the valve plate is completely separated from the valve seat, increasing the friction force, making the opening torque appear the minimum optimal form, and the sealing is tight and reliable, durable.
