對(duì)閥門密封性能的要求，要防止泄漏角度出發(fā)。根據(jù)其泄漏的不同部位和程度，導(dǎo)致閥門的泄漏情況不同，因此，需要提出不同的防漏措施。1閥門密封性原理密封就是防止泄漏，那么閥門密封性原理也是從防止泄漏研究的。造成泄漏的因素主要有兩個(gè)，一個(gè)是影響密封性能的**主要的因素，即密封副之間存在著間隙，另一個(gè)則是密封副的兩側(cè)之間存在著壓差。閥門密封性原理也是從液體的密封性、氣體的密封性、泄漏通道的密封原理和閥門密封副等四個(gè)方面來(lái)分析的。01液體的密封性液體的密封性是通過液體的粘度和表面張力來(lái)進(jìn)行。當(dāng)閥門泄漏的毛細(xì)管充滿氣體的時(shí)候，表面張力可能對(duì)液體進(jìn)行排斥，或者將液體引進(jìn)毛細(xì)管內(nèi)。這樣就形成了相切角。當(dāng)相切角小于90°的時(shí)候，液體就會(huì)被注入毛細(xì)管內(nèi)，這樣就會(huì)發(fā)生泄漏。發(fā)生泄漏的原因在于介質(zhì)的不同性質(zhì)。用不同介質(zhì)做試驗(yàn)，在條件相同的情況下，會(huì)得出不同的結(jié)果?？梢杂盟?，用空氣或用煤油等。而當(dāng)相切角大于90°時(shí)，也會(huì)發(fā)生泄漏。因?yàn)榕c金屬表面上的油脂或蠟質(zhì)薄膜有關(guān)系。一旦這些表面的薄膜被溶解掉，金屬表面的特性就發(fā)生了變化，原來(lái)被排斥的液體，就會(huì)侵濕表面，發(fā)生泄漏。針對(duì)上述情況，根據(jù)泊松公式。</p><div
