內(nèi)螺紋與承插焊截止閥的閉合原理是，依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質(zhì)流通。截止閥只許介質(zhì)單向流動(dòng)，安裝時(shí)有 方向性。截止閥的結(jié)構(gòu) 長度大于閘閥，同時(shí)流體阻力大，長期運(yùn)行時(shí)，密封可靠性不強(qiáng)。

The closed principle of the internal screw and socket welding stop valve is to rely on the stem pressure to close the sealing cover of the disc and the sealing cover of the seat to prevent the circulation of the medium. The globe valve only allows the medium to flow in one direction, and the installation has directivity. The globe valve has a structure length greater than gate valve, while fluid resistance is large, and the sealing reliability is not strong in the long run.
