偏心半球閥的特點 偏心半球閥的特點之一啟閉無磨擦.由于采用偏心結構.閥門在關閉的過程中.球體逐漸靠近閥座,到關閉位置接齄;在開啟時球體離開密封位置即可脫開.開啟扭矩小;第二個特點是密封面可實現自清潔.球體離開閥座時,介質可沖去密封面上的積聚物.對于易結晶介質.球體在關閉過程中可切除介質結晶達到密封的目的.避免了其它閥門無法開關的弊端;第三個特點是密封嚴緊,球體、閥座是雙金屬.采取不同工藝.密封面可組合成防腐、耐磨等各種類型.滿足不同工況的需求,密封是球面線接觸,靠二維偏心實現零泄漏。 |
Biased half ball valve characteristic Biased one of half ball valve characteristics opens shuts, because uses the eccentric structure, the valve in the shuting down process, the spheroid gradually approaches the valve seat, completely contacts to the off-position; When opening the spheroid leaves seals the position the completely to withdraw, opens the torque to be small; The second characteristic is the packing surface may realize from cleanly, when the spheroid leaves the valve seat, the medium may flush away in the packing surface the agglomeration, regarding is easy to Cfystallize the medium, the spheroid may excise the medium crystallization in the closure process to achieve the seal the goal, avoided other valves being unable the switch malpractice;The third character-istic is the seal close, the spheraid, the valve seat are the bimetal, adopts thedifferent craft, the packing surface may the group synthesize the anticarrosion, be wear-resisting and so on each kind of type, satisfies the different operating made the demand, the seal is the spherical surface, depends on two-dimensional biased realizaton zero to divulge. |

工作原理 偏心半球閥由閥桿帶動球體繞旋轉中心A轉動時,球體由B點移動C點,此時相對閥門中心O,從B到C的軌跡為一凸輪狀偏心,向下進入閥座使閥門關閉保持密。該閥由于存上上述凸輪原理.閥門關閉件從開啟到關閉過程中,作用在閥座上的力逐漸增加,即關閉件表面與閥座由脫離至接觸,并逐漸增大密封比壓.直至密封.反之亦然。這就大大改善了以往球閥的密封狀態和密封效果,適合高溫高壓及易結晶磨損嚴重的場合使用。 | Principle of work The biased half ball valve when circles the center of rotation A rotation by the valve lever impetus spheroid, the spheroid by B moves C, this time relative valve center O, from B to the C path is a cam shape bias, enters the valve seat toward un-der to cause the valve closure maintenace seal. This valve because has above cam principle, the valve closure from opens to the closure process in, affects the strength gradually increases on the valve seat, namely the shutting down surface and the valve seat by completely are separated from to the contact, and gradually increases the seal to compare the pressure, until completely seals, vice versa. This greatly im-proved the former bll valve seal condition and the seal effect, suits the high tempera-ture high pressure and is easy to crystallize wears the serious situation use. |
適用場合 我公司半球閥產品按用途分為:通用閥、管線閥、料漿專用閥、燃氣專用閥、石油化工專用閥、煤粉噴吹專用閥六大系列。在石油、化工、冶金、電力、燃氣、排灰、噴煤粉等行業是閘閥、截止閥、Y型閥、球閥的更新換代產品。 | Suitable situation The our company half ball valve product divides into according to the use: the pipeline valve, the material thick liquid special-prupose valve, the fuel gas spe-cial-purpose valve, the petroleum chemical industry special-purpose valve, the pow-dared coal spurt blows the special-purpose valve six big series. In the petroleum, the chemical industry, the metallurgy, the electric power, the fuel gas, the platoon ash,spurt profession and so on powdered coal is the gate valve, the cut-off valve, the Y valve, the ball valve renewal product. |
