The present invention relates to a new sealing method for valves, which uses an inner-hollow elastic material as the valve sealing element, and generally uses rubber material. The inner part of the sealing element is hollow, the inner part is filled with flowable substances, and a pressure relief device is added, which is placed between the valve plate and the sealing surface of the valve body. When the valve is in the open and conductive state, the sealing element is in the pressure relief state, and the sealing element is in the pressure relief state. There is no contact or light contact with the sealing surface of the valve plate. When the valve needs to be closed, the valve plate moves until the closing position is reached. The pressure reducing device pressurizes the flowable material in the sealing part, expands the sealing part, and fills the gap between the sealing surface of the valve plate and the sealing surface of the valve body to achieve the sealing purpose. When it is necessary to open the lead-in valve, the pressure-reducing device first decompresses the flowable material in the seal, shrinks the seal, and releases the seal, then the valve plate moves to the lead-in position of the valve. The advantage of this sealing method is that the valve operates with small resistance, not easy to wear, good sealing effect and long service life.

一种阀门密封方法
:本专利技术涉及一种阀门密封方法,用于阀门的密封,目的是解决闸阀、蝶阀、球阀等依靠摩擦力密封的阀门存在的操作阻力大、密封效果不理想、使用寿命较短等问题。
技术介绍
:阀门是工业生产中和日常生活中不可或缺的物品,作用很大,闸阀、蝶阀、球阀应用最为广泛。这类阀门水流阻力小,能耗小,所以应用广泛,但这类阀门的密封依靠阀门的阀板密封面与阀体密封面或密封面上附着的柔性密封件之间的摩擦力来密封,操作阻力较大,而且密封效果不太理想,磨损比较快,导致使用寿命较短。虽经改进,前述问题也未彻底解决。
技术实现思路
:为了克服目前阀门密封方法存在的不足,本专利技术提供一种新的阀门密封方法,该方法能够很好地解决目前阀门密封方法存在的问题。本专利技术解决其技术问题所采用的技术方案是:采用一种内空式弹性材料作为阀门密封件,一般采用橡胶材料,这种密封件内部是中空的,内部充填可流动物质,外连加减压装置,阀门密封件置于阀板与阀体的密封面之间,通过加减压装置对密封件内可流动物质的加压和减压使密封件膨胀和收缩,达到密封和解密封的目的。当阀门处于开启、导通状态时,密封件处在泄压状态,其与阀 ...
